Explained Answers to Frequently Asked Questions (EAs-FAQs)
Do You Have Any More Questions?
Please read questions bellow and if you can not find your answer, please send us your question/s, we will answer you as soon as possible.
Q1. What is Dual Global Mobile SIM all about?
A1. The Dual Global Mobile SIM is a World Free Roaming GSM SIM with a + 44 UK & +1 US Tel numbers in the SIM to place and receive calls in 220+ countries and free incoming calls in 120+ countries worldwide.
Q2. What do you mean by Free Roaming?
A2. It means you are not charged any connection fee for using the Dual Global Mobile for calling & receiving calls, sending and receiving sms, browsing, etc. outside the domiciled country of the network provider which may be your country of origin when you travel abroad with their SIM and/or Network. When you are not charged any connection fee or no money deposit/bond required for using your local SIM and/or Network overseas outside the domiciled country of the network provider, but you are only billed or pay the required affordable outgoing rates, it is ‘Free Roaming’
The Dual Global Mobile SIM has Free Roaming feature. This is in contrast with your local GSM Network providers when you use their local SIM and/or Network to travel abroad for business, conference, vacation, pleasure,, etc. you are charged a high connection fee (which in most cases is added to the per minute billing) and by the time this sums up itself per minute, you will be paying very high calling rate and with such high connection fee, they cannot offer you (their customer or subscriber) free incoming calls in many countries when you use their SIM/Network outside the domiciled network country.
With such mobile global telephony billing system when traveling overseas, you are in for a huge telephone bills to be deducted from your credit card, bill or bank account. And this charge may be separate from other pre-travel obligation charge/s some network providers would want you to deposit money as bond before your phone may be programmed for roaming overseas!
So many international travelers do not use their local SIM effectively when they travel abroad with it due to high charges for calling and/or receiving calls and sms services. If you cannot use your local SIM abroad effectively due to the above stated reasons and other reasons such as no coverage in a particular country, poor connection and interruption during calls and/or receiving, then you need to get a Dual Global Mobile SIM for any of your trips abroad! The Dual Global Mobile SIM has a zero or free roaming charges!
You can imagine you are been charged a roaming fee [in other words a connection fee] in addition to high rates for calling and/or receiving calls when traveling abroad. This is the reason a lot of travelers using local SIMs to roam overseas may be able to see incoming calls, but afraid to pick up the call because it would cost them much. This is not applicable to the Dual Global Mobile SIM. You are not charged any roaming fee and you have free incoming call in 120+ countries worldwide. So, if your loved ones, friends and business associates call you, you are free to answer the call and you could talk with them straight away without the fear of high charges! You are not afraid to pick up the calls instead of using an online call (which you would still pay) or getting a local SIM in that country (which you would still pay for it and may not stay to use it because you are not a resident in that country) just to place and receive call for the few days or short period you will stay there. This does not make any business sense. And you do not need to buy local SIM cards in any country you travel to, just to stay in contact with your loved ones, friends or business associates, which would cost you much and again, does not make business sense.
What you need is the Dual Global Mobile SIM – ONE SIM for the whole world! From the airport upon landing, you have access and network with the Dual Global Mobile SIM to receive call at no cost and place calls at a very low rate.
If you still want to have a local number of the country you wish to travel to, it is possible with the Dual Global Mobile SIM. Apart from the +44 UK & +1 US numbers that come with the SIM, you can subscribed for a local DID (Direct Inward Dialing) Tel number in that country through the Dual Global Mobile platform and you use with your SIM! Again, ONE SIM for the whole world. Currently, we have DID Tel numbers available from 60+ countries and in 4000+ cities worldwide. We are constantly adding more DID Tel numbers from other countries. You can get more information on renting a local telephone number (DID) in the country you travel to or planning to travel to in our website by clicking on “Products” link on the homepage and then navigate to ‘DualDID’.

#- Caller must call you on your UK +44 number in order to receive a free incoming call when in the US and also in other countries where there is free incoming calls.
* Free incoming call countries are subject to change without notice on our website. However, more free incoming call countries are constantly added to the list!
*Free incoming calls may not be available in all periods of the day and week – peak, offpeak or super offpeak.
** In some countries, you would have to select a particular network to roam on in order to have free incoming call.
Q4. Once I received the SIM, what do I do?
A4. You cut if off from the SIM card, insert into any unlocked GSM Phone and it will register in our database and you will see receive an SMS telling you your UK number. Also it might show you Profiles (Automatic, USA, Global & Prime). It will be helpful you follow the instructions in the User Guide to guide you properly on how to use your Dual Global Mobile SIM. For the US number, you would need to dial *160# from the phone the SIM is inserted to receive your US number.
Q5. Why do you say “No Network Problem”?
A5. Because the SIM roams on any of the existing GSM networks in the country you are in. For instance, if you switch on your phone with the SIM inserted, after booting the SIM will automatically pick up a network signal of any of the GSM networks available with the very strongest signal in that state/city/town/area in that country. As you move, the SIM automatically detects and selects network with the strongest signal in that area and automatically switches to that network and vice versa without any noticeable effect on the call quality, neither any call (outgoing or incoming) disruption or it will remain on the network it initial picked up if it is very strong after the booting of the phone with the Dual Global Mobile SIM inserted!
For instance, if you are in an area with a very strong GSM network “A” and as you move or travel to another city or area where the GSM “A” network signal is weak or not even available or no coverage in that area, the Dual Global Mobile SIM automatically switches to any available strong or average GSM networks signals say, “B”, “C”, “D”, or “E” networks, depending on the number of GSM companies’ networks operational in that country.
Sometimes, if there are few GSM networks in a particular area , you may just need to manually select in your phone and roam on any of the few GSM networks in that area. You can also decide to manually select a network and saved your roaming on that network. Your Dual Global Mobile SIM never lacks network. It is only and only when ALL THE GSM networks operational in that country are switched off that the Dual Global Mobile SIM may not be able to pick a network signal to roam on. But such switching off of ALL the GSM networks in a country is very rare. Even though this occurs, then your Dual Global Mobile SIM is readily much available for use when you travel abroad unlike would be those shot down local GSM networks in that country which may become redundant!
Q6. Why this SIM is called Global?
A6. Because it is specifically designed for global use in 220+ countries with zero roaming charges and free incoming calls in 120+ countries unlike local SIMs that are designed mostly for affordable local use but very expensive global use, high roaming charges and limited global coverage when traveling abroad.
Q7. Does it cost me much to use it in my country like using a local SIM to call and receive calls?
A7. The Dual Global Mobile SIM is specifically designed for the frequent, periodic and occasional international traveler. The purpose is to cut down roaming charges and reduce high costs for calling and receiving calls when traveling abroad from one country to another for business, conferences, vacations and visit, etc. You would save good money for using the Dual Global Mobile SIM when roaming the world if you do or intend to place and receive calls frequently, periodically or even occasionally instead of using a local SIM to roam with limited coverage, high calling rates and no free incoming calls in most countries. It could save you between US$2400 and US$5800 and you would have wide global coverage and call clarity for using the Dual Global Mobile SIM to roam overseas than using your Local SIM to travel overseas within a period of 6-12 months in a year. By all standards, the Dual Global Mobile is a good reason why you need it when traveling overseas! Why we do not compete with local network SIMs in placing and receiving calls locally or when placing calls overseas while stationary in your country of residence, the Dual Global Mobile SIM calling rates may be cheaper when calling some local destination numbers and also when calling some countries overseas from your country of residence. You may need to look up our call rates online using the ‘Rates Calculator’ and compare with your local network call rates locally and when calling some countries overseas.
Q8. How about outgoing caller ID?
A8. Normally, the Dual Global Mobile SIM has +44 UK & +1 US numbers, which means two telephone numbers – one a UK telephone number and the other a US telephone number. You can program your outgoing Call ID to either be the + 44 UK complete number or the +1 US complete number. What would show on the phone screen of the party you are calling would be either of the number you program to be your outgoing Call ID no matter the country you are in anywhere in the world! Also, if you subscribe to any of or many or all of the DualDID telephone numbers, you can as well program your Dual Global Mobile Call ID to be any of the DualDID telephone number in that country you have subscribed. However, you would need to use the DualPBX feature in your smartphone with to achieve this. You can also receive calls placed to your DualDID telephone number no matter the country you are in anywhere in the world.
Q9. Am I charged a monthly or yearly fee or any access charge fee for using the Dual Global Mobile SIM?
A9. No! You are not charged a monthly or yearly fee for the SIM neither for the UK number nor are the US number and you not charged any access fee for using the Dual Global Mobile SIM. We have abolished all those monthly or yearly fee for using the Dual Global Mobile. No annual SIM renewal fee for the SIM and we have abolished the 60-day rule with the use of the US number of the SIM.
Other Global SIMs will charge you a monthly or yearly fee and the 60-day rule applies to the US number of their SIMs. The 60-day rule requires
you should be physically present (or you gave someone) your SIM to use when the person travels to the United States or Canada every 60 days and the SIM registers on a USA soil network or on a Canada soil network. If you are residing in the USA and your SIM registers at least once in every 59 days period in a year, you are not subject to this 60-day rule. If you cannot keep to this rule, you will use your US number of the SIM [though you can still get a new one] or you can opt for a monthly fee from $4 to $20 in order to keep your same US number. But must you continue to change your US number every 60 day period if you do not travel to the US every 60 day? The answer is No! You can as well do not bother for this 60-day rule or the monthly fee for keeping the USA number and it would be recycled on the very 60th day of the SIM out of US or Canada soil.
Dual Global Mobile has abolished all this rule and you can just have your first time activated UK and US telephone numbers as permanent numbers without losing any of the numbers including the US number and without us charging you a fee for the US number either any monthly or yearly.
Q10. Can I decide on a particular state and city telephone code for the US number to be assigned to my Dual Global Mobile SIM? For instance, I want a US telephone number to be Washington, DC that is with city/area code (202) or to be state of New York in Long Island (516)?
A10. For the original IMSI +44 & +1 US Numbers of the Dual Global Mobile, you do not have a choice on the particular state and/or city telephone code. It is automatically assigned to the SIM. The US number of the Dual Global Mobile SIM is provided based on availability from few states across USA hence it is automatically assigned to your SIM to enable us exhaust quotas given to us for a particular state at a particular period. However, if you want a specific choice or preference of the US number tied to a state/city and code, then you would have to subscribe for a DualDID Local Telephone Numbers that has wide availability across the 50 states in the US with preferences in city/area telephone codes. The DualDID Local Telephone Numbers are also available from more than 50 countries worldwide with preferences with city/area telephone codes in more than 4000 cities worldwide as well. To see more info on the DualDID, click here. The good news is that you can subscribe and map any of the DualDID local telephone numbers to any of the following phones:
* Dual Global Mobile SIM
* Your country local Regular phone
* Google Talk
However, we cannot guarantee fully that you can successfully receive calls place to your subscribed DualDID telephone number on your Local Regular country phone or VOIP or the Google Talk. But we do guarantee fully for the Dual Global Mobile SIM.

Q12. What is Web Initiated Call?
A12. Web Initiated Call means using your Dual Global Mobile account online logged in from any electronic device with internet connection to initiate a call using any phone number, not necessary the Dual Global Mobile SIM number but any valid phone number could be used to initiate a web initiated call including the Dual Global Mobile SIM number. Web Initiated Call simply means initiating calls from your Dual Global Mobile account online while the SIM Initiated Call means initiating Call directly from your Dual Global Mobile SIM inserted in an unlocked phone.

With this, they would feel more comfortable to call your Dual Global Mobile and/or DualDID local telephone number in their country as they may not need to pay a long distance fee for calling your local number if they are on a monthly plan with their telephone network provider as with most businesses in the United States. With the Dual Global Mobile SIM and/or the DualDID local telephone number subscription, you could have virtual and even physical offices in more than 20 countries worldwide and have local telephone numbers subscribed in those countries and you could either integrate and map all these numbers with your Dual Global Mobile SIM or any regular phone number (if your local provider have such features for your phone plan) so you can answer and place calls from and to your business partners from one location anywhere you are in the world. Your office/s moves with you especially with your Dual Global Mobile SIM, and this is absolutely possible with the Dual Global Mobile.

A17. Absolutely Yes!

A19. Yes! The Dual Global Mobile SIM has data (internet) access in most countries where we have coverage.

Q25. Why should I subscribe, order and use the Dual Global Mobile SIM whereas I can subscribe, order and use a SIM provided by my local network in my country?
A25. Good question! The Dual Global Mobile Roaming SIM is not a local SIM provided by a local network. The Dual Global Mobile Roaming SIM is a Global Free Roaming SIM for global use when you travel abroad from one country to another or to multiple countries for business, conferences, vacations or pleasures. The issue here is beyond just having a SIM to travel abroad but the cost in roaming, cost in calling, cost in receiving calls, voice clarity, easy access to manage SIM account, call forwarding, reading of voicemails, etc. If you are a traveler whether frequent periodic or occasional, you would know the importance of a personal mobile phone when you arrive at the airport to call someone to pick you at the airport, to place a call to your intended host, to place a call to your loved ones and family members, friends and business associates all at affordable outgoing calls, free incoming calls so you do not need to sms the person that you would call back due to high cost of receiving calls on your local network phone abroad, voice clarity and very wide coverage and without high phone bills; by all standards the Dual Global Mobile SIM is all what you need! You will be in constant touch with your loved ones, friends and business associates anywhere you are in the world with the Dual Global Mobile SIM.
When discussing low cost of use and worldwide coverage with the use of Dual Global Mobile SIM; let’s assume you have your Dual Global Mobile SIM and your friend has a local network phone and both of you are traveling to the United Kingdom and to the United States and to Canada and to Australia and to Hong Kong and back to your country for a period of just 30 days, you will be surprised that your friend with the local network would be billed sometimes high charges for receiving calls when both of you arrive in the UK while with the Dual Global Mobile, you will receive free incoming calls; and then to the United States, you will still be receiving free incoming calls while your friend would not, he/she would be billed by his local network provider for receiving calls; and then to Canada, the story continues from Canada to Australia to Hong Kong and back to your country of origin. You will enjoy free incoming calls with the Dual Global Mobile SIM while your friend will not!
This has not even considered the cost of outgoing calls both of you will place with the different networks. You will have low outgoing calls than that of your friend with the local network. Assuming if when you get to Hong Kong and you decided to visit more one or two countries, you will be surprised that your friend may not be able to receive and/or place calls in those additional one or two countries because his local network providers does not have coverage in those countries but with the Dual Global Mobile, you can be assured of receiving calls and placing calls because the Dual Global Mobile coverage is virtually worldwide. In terms of savings in dollars, you will save up to $1500 with the Dual Global Mobile SIM while your friend may accumulate a telephone bill more than $2500 when both of your return to your country back from your overseas trip. Now, just in 30 days globe-trotting, see the cost savings and cost accumulation; consider a 180 days globe-trotting? Every person no matter his or her financial situation, wealthy, rich, average, poor would want to save the next one (1) dollar instead of just wasting it. And we are sure you would like to do the same!
Q26. What happens if I misplace or lost my Dual Global Mobile SIM? Can I re-order for a replacement SIM with the exact UK number for the previous SIM to be integrated with the new SIM?
A26. Yes! If you lost or misplace your SIM, you can order for a replacement SIM (free of charge) but shipping and handling cost would be paid by you. And we could port your old Dual Global Mobile SIM UK number to your new SIM as well as your airtime credit balance, call transactions of your old SIM into your new SIM account. However, please note that the process of porting your old number to the new SIM may take a little time as we have to put a formal request and wait for approval, etc. and then begin the porting and integration process. The other option if you do not have the patience is to order a new SIM with a new UK number instead of the old. This does not take time apart from the time in waiting for the shipment containing the SIM to arrive at your destination. The activation process takes 3-5 minutes for your SIM to be up and running.
Q27. How long does my purchased and unused airtime credit expires?
A27. Generally speaking your airtime credit purchased and loaded does not expire as long as your SIM is valid.
Q28. Does Dual Global Mobile SIM incorporates SMS and MMS features and do such work well?
A28. Presently, the Dual Global Mobile SIM has an SMS feature where you can send and receive an SMS anywhere you are in the world. However, note that SMS transmission between a GSM network and a CDMA network may sometimes become unsuccessful. This is not a Dual Global Mobile problem but a general GSM and CDMA networks’ problems. But for SMS between any or multiple GSM networks goes well. For the MMS feature, we are looking at incorporating this feature into the SIM soon and once incorporated, this feature will automatically be integrated and popped up in your Dual Global Mobile SIM.
Q29. Can I use the Dual Global Mobile SIM in my iPad, iPhone and other tablets?
A29. Absolutely Yes! As long as the device has a SIM compartment whether for a standard (mini), micro or nano GSM SIM. The Dual Global Mobile SIM Card is a TriplePunch SIM Card, meaning the SIM can automatically fit into a mini, micro or nano SIM compartment of a phone or tablet. There is a clear but faint line marked to differentiate a nano SIM size from the micro SIM size and from the micro SIM size from the mini (regular) SIM size in the SIM Card. You can see these lines clearly when you look at it from the back of the SIM, though you can see it as well at the front of the SIM. Depending on your phone or tablet SIM compartment type, carefully punch out the SIM from the faint line surrounding the golden chip area on the card to get the nano SIM size to be inserted into a nano SIM phone or tablet or carefully punch out the line sounding the micro SIM to produce the micro SIM and insert into your phone or tablet.
Q30. What about those of us who are seamen, sailors, yachtsmen and women and offshore platform workers, can we use the Dual Global Mobile SIM to receive and place calls to our loved ones, business associates and friends from our base or from the sea?
A30. Yes! The Dual Global Mobile SIM is a Mobile Seal SIM (Sea, Air and Land) Mobility SIM, which means it works when on the sea, in the air and on land and it works in those offshore platforms and regions according to the country/region it is situated. You will also receive free incoming calls when in any of those offshore platforms as long as the country/region has free incoming calls. This is also applicable to our low outgoing call rates when in those offshore platforms in accordance with the country/region.

Q33. I do business international and have business partners, customers and contacts in various continents worldwide such as the USA, UK, France, Germany, Netherlands, China, India, South Africa, Taiwan, etc., what use and advantage would the Dual Global Mobile be over my local mobile network provided by my local telecom company?
A33. If you have or do business across the globe, then the Dual Global Mobile and its DualDID (Local Telephone Numbers) & Dual800 (Toll Free Numbers) would be best for your businesses. Let’s say you have a business presence directly or indirectly in the US, UK, Germany, Netherlands, China, you can provide your Dual Global Mobile USA or UK number and/or DualDID local Telephone numbers for each country to your business partners depending on the country to call you. They calling you on the provided local number you subscribed for their city/state/region in their country, they may not be charged if they have an unlimited monthly plan with their local network provider or even though they may be charged for calling your SIM or DID number, it will be local rates. And if you are unable to answer the calls, they could drop a voice mails for you to retrieve and listen and then call them later. They are not calling long distance calls when calling you and if they are charged by their local network provider without a plan, it is a local call rate and of course this gives them more confident and trust to do business with you. Telecommunications is so vital in any distance or even close business contacts or business relationships that without it [that is, absence of you communicating with your business partners and they communicating with you via the phone] there may exit a tense form of distrust or lack of confidence in doing business with the other.
Q34. That reminds me! Can I port my local mobile telephone number to the Dual Global Mobile network or port my Dual Global Mobile number to my local mobile telephone network in my country?
A34. You may be able to port other UK Telephone Numbers to Dual Global Mobile platform. If this happens, please note that we may not be able to offer you Free Incoming Call for that UK Telephone Number. We could only offer Free Incoming Call to our own Dual Global Mobile allocated UK Telephone Numbers. However, you may not be able to port your Dual Global Mobile UK Telephone Number to other UK Telecoms Network providers.
Q35. Last question; any legal implication for buying the SIM and using in my country?
A35. No! There are no legal implications for buying and using the Dual Global Mobile SIM in your country. It is just as buying a cell or mobile phone handset and/or its accessories in any country you travel to as long as the handset is suitable for your use and you could use the handset in any country you travel abroad to! The answers provided for question #33 above could also clarify question #35. In further clarifications, the Dual Global Mobile is a Mobile Virtual Mobile Network Operator (MVNO) with its regulatory rules somehow different from that of MNOs. Most of your popular local GSM networks in your country are Mobile Network Operators (MNOs) with regulations by their various Telecoms Regulatory Agencies.

8b.Q2. While we do in the past have dedicated live telephone lines on 24/7 basis for our global customers – from all parts of the world that do call for sales and technical questions and we pay sums of money to these outsourced Live Telephone Answering Global Services ; this drained a huge sum of our gross profits. After some years of offering such services, we decided to stop it and started attending to all our new and current customers globally in providing 24/7 Online Support for both Sales and Technical Questions and Queries and thus eliminated whatever temptation of passing the cost of such live telephone answering services to be borne by our customers and still maintain the affordability and competition of all our telecoms global free roaming products and services in the market place.
