Can I use a Sim card in a non GSM phone?
Unfortunately no, but you can buy an unlocked world band - GSM phone in the "Phones" section of our site.
How do I know if my phone is unlocked?
You should assume that your cell phone is not unlocked unless you specifically purchased an unlocked phone. An unlocked will accept a Sim card from any carrier and find the network if it has the necessary GSM bands. A locked phone products an error message such as "Sim Registration Failed" or "Invalid Sim".
How can I unlock my phone?
Most cellular carriers including T-Mobile and Cingular Wireless will unlock your phone for you if you have been a customer of theirs for at least 3 months. If your provider will not unlock your phone, there are services on eBay that will do it for you. We will unlock most AT&T phones for a $15 fee including AT&T Blackberries.
Can I use my credit card to refill my Sim card?
The answer is yes. You can refill you Sim card at thousands of locations in the USA, and most all of them will take a credit card. On-line or phone refills may be accepted. Check with the carrier. The best way to refill is online here at mrsimcard.com. Just click the red TOPUP link at the top of each page. If many cases we can send the refill credit direct to your telephone. Please include the mobile number the topup is going to.
Does my Sim card ever expire?
Yes, your account can expire, so you must use your Sim card once every 2 to 3 months to keep it active depending on which cellular provider you chose to go with. Please check the ordering page for your Sim card to get the exact time period. One way to keep your Sim card active is to simply place a call or send a text message using your Sim card once every 30 days. In the case of Caribbean sims, you can keep it alive by sending a tiny topup to the line once every 30 days. The credit stays on the line til next time you go to the Caribbean.
How will I know how to use the services on my Sim card such as voicemail?
When you receive the Sim card, you will also receive detailed directions in English for all the functions and services that the Sim card account offers including voicemail, how to recharge your Sim card, how to check your credit, and more.
How do I set my phone up to use data services?
When you receive your Sim, you can contact your carrier’s customer support line for assistance. Most of the time, they will be able to send the data settings directly to your phone so you do not have to input anything yourself. If the sim is for use on the iPhone, then please refer to the iphone settings page for the APN settings necessary for your iPhone, or call +1-703-953-2272.
Will my Blackberry work with my Sim card?
With most prepaid Sim cards your Blackberry will only work for phone calls and SMS messages. The Blackberry email service will only work if the carrier offers a specific prepaid blackberry service. We offer prepaid blackberry service in the USA on T-Mobile, in the Caribbean on LIME, and Digicel, in Europe on Orange, and Call in Europe for the UK, France, and Germany. In using prepaid blackberry service, you do need to use an unlocked blackberry device. Additionally, if you are using the same device you use on your home blackberry service, you will need to release the "blackberry pin" from your home service to activate the prepaid service. You can re-attach the pin when you return home.
What is a Sim card (Sim chip)?
The SIM (Subscriber Identity Module) card, about the size of a postage stamp, has a small chip in it that contains all your account information for the cell phone company.
What is a Prepaid Sim card?
A prepaid Sim card is a Sim card with a "pay as you go account". There are no contracts or monthly minimum usage. Just add credits to your account, and credits are deducted as you use your phone.

What is the deal with Global Roaming Sim Cards?
We now have on offer the top global roaming sims available for sale. The "Tourist Mobile" German sim comes with a (+49) German number and is remarkable in its efficiency and stability. The "Worldsim" comes with a (+44) UK number and features 55 countries with free incoming calls and is very popular with business users. The "Global Travelsim" comes with a (+372) Estonian number and offers 60 countries with free incoming calls. This sim is the most pervasive product we offer.
Ok you ask, "Why do you offer four Global Travel Sims?"
The answer is personal preference and free incoming countries offered. If you had to pick one that covers the most area and with the least amount of fuss, then the "Travelsim" or the "Worldsim" are the easy choice. If your travels take you to Germany and eastern Europe, then the "Tourist Mobile" sim is the one for you. If you are looking for a product that just works and works well with a low average call cost, "Tourist Mobile" Travel sim is the one. It has few free incoming countries, but is dual featured in that it works with "Callback" and "Direct Dial".
Callback versus Direct Dial. What is the diff?
Direct Dial is what you do now. You dial a number with the international dialing code ..ie +1-703-953-2272, wait for the call to complete and talk to your party.
Callback is the way you save a bundle on roaming costs. When you dial your call, the telephone triggers the network switch which does two things. It calls you back and then it dials your number. This little twist is called "Callback". The low cost global roamers all feature "Callback".
