11. Troubleshooting Questions
    • Will¬†a OneSimCard international SIM card work with my mobile phone?

      OneSimCard will work with almost any unlocked GSM tri-band or quad-band cell phone. A partial list of compatible cell phones that we have tested can be viewed here.

      If you need to unlock the phone, we suggest contacting your carrier or phone manufacturer for unlocking information or services.

      If your phone is not a quad-band phone, please make sure that the bands of your phone are those required in the country of your travel. You can look it up here.

      If you are still unsure whether your cell phone is compatible, contact support or purchase an international cell phone and SIM card bundle from us, which all come preloaded with our international SIM card, $10 balance  and OneSimCard Apps Installed.

12. Troubleshooting Questions
    • I have an Verizon or Sprint Smart Phone ( iPhone, Samsung Galaxy, HTC, etc). Will OneSimCard work with my phone?

      Verizon and Sprint now offer dual mode - CDMA and GSM phones, which are capable of working on GSM networks. You can request Verizon and Sprint to unlock the GSM portion of the phone for international travel and they will most likely do this for you. However, Verizon and Sprint usually does not unlock phones 100% - they do this partially, so you are not able to use the phone while in USA.

      In such Verizon and Sprint phones you can get invalid message when inserting OneSimCard SIM or your phone does not find US networks. Verizon and Sprint unlock their phones in such a way that you can't use it in USA, but once you are out of the country the SIM will be accepted. Unfortunately, there is no way to tell the difference with this kind of unlocking if the phone is not unlocked or partially unlocked to work only outside of USA. In our experience, once this kind of phone leaves USA, it starts working.

13. Troubleshooting Questions
    • Can I move balances from one SIM card to another?

      We allow moving balances from one SIM card to another in the following cases:
      • Corporate Accounts - anytime.
      • Individual Accounts - only when a SIM card is lost or stolen. The remaining balance from your lost or stolen SIM card can be transferred to another SIM card on your account or you can order a new SIM card if you would like to keep your original European number from the lost SIM.
14. Troubleshooting Questions
    • What should I do if my OneSimCard phone or SIM card is lost or stolen?

      If your phone or SIM card is lost or stolen and automatic recharge is on, this could be a serious problem.

      To prevent this, log in to your account and activate the option to block your service immediately after you notice your phone or SIM card is missing. You can find this option in the My SIM Cards menu. Your OneSimCard service for this SIM card number will be instantly blocked. The remaining balance on your lost SIM can be transferred to another SIM card on your account or you can order a replacement SIM card if you would like to keep your phone numbers from the lost SIM.

      Alternatively, you can contact customer service online or call 001-617-313-8888 for assistance.

15. Troubleshooting Questions
    • I just activated my SIM card and can't make a successful test call. What's wrong?

      If you just activated your SIM card and can not make a test call by following the instructions in the user manual, you will likely just need to power off the phone and power it back on again. The phone should automatically re-register with one of our partner networks. Remember, if you answer the test call when it rings you will be charged for the call.
      We strongly recommend you to watch very short video tutorials that will help you to understand how to make calls, SMS and data on your OneSimCard Phone.

      These videos are available in the Help Menu of your OneSimCard Portal. You need to log in to your OneSimCard account first and then proceed to the Help Menu to be able to access these videos.

16. How To Use Questions
    • There is no OneSimCard Menu (SIM Toolkit) in my Android phone. How can I fix this?

      Some recent Android upgrades to versions 4.2.1 and 4.2.2 have a bug causing the OneSimCard Menu, labeled as SIM Toolkit, to be disabled.

      If you do not see the SIM Toolkit app in your Android phone, please try doing the following:

      Go to Settings>Security>Setup SIM Card Lock>Lock SIM Card. It will ask for the default SIM PIN. Enter 0000. Power off the phone and turn it back on. The SIM Toolkit app will then become available, though it might take 1-2 minutes for the phone to display it.

      On Android version 5.1 go to Settings > SIM Cards > SIM Toolkit

      Once you have access to the SIM Toolkit, select it, scroll down to Settings, enter 1101 and press confirm. Your phone will now be able to dial normally.

17. How To Use Questions
    • I have a Verizon or Sprint "World Phone"¬†from BlackBerry, Samsung, LG KP series, etc., can I use it with OneSimCard?

      Yes, if you have a World Phone from Verizon or Sprint such as the BlackBerry (Bold, Curve, Tour, Pearl, Storm, 8830); LG (Fathom); LG KP Series, HTC (Touch, Ozone, Imagio); Samsung (Saga, Intrepid, Renown) you can use it with OneSimCard service. It may only require the special dialing instructions below to make outgoing calls (there is no additional charge). Receiving calls is the same as with any other phone.

      To make an outgoing call you may need to do the following:

      Initiate your call by sending a free SMS message from the regular SMS menu (not the OneSimCard Menu) of a OneSimCard enabled phone:

      To: 9146
      Message: 00 + Country Code + Number

      For example, to call to Boston USA you should go to the SMS menu of the phone and send a message:

      To: 9146
      Message: 0015844440686
      After your SMS is sent wait approximately 3-10 seconds. You will get a callback as usual and your call will be connected to the destination number.

       

      Please Note:

      1. You can not send this SMS from the SMS OneSimCard Menu of the phone, it must be sent using your phone's standard SMS function. You will not be charged for sending this SMS to 9146.

      2. If you see on the screen that the message has not been sent, make sure that the SMS settings of your phone are correct and that the SMS Center number is set to: +3725099000

18. Rates and Cost Questions
    • How much does it cost someone in the US or Canada to call to my OneSimCard cell phone?

      Many U.S. and Canadian carriers can charge more than $3/minute to connect to an Estonian mobile number, the primary mobile number for a OneSimCard global SIM card. Your SIM card includes a U.S. number which will be much less expensive for people to call.

      Callers can also use one of the Common Access Numbers (CAN) that we provide to you free of charge in more than 10 countries. Your OneSimCard account will simply be charged an additional 20c/min to the incoming rate in the country you are in to receive those calls. There is also the option of ordering a dedicated Personal Extra Number (PEN) in Canada and many other countries that will forward all calls directly to your OneSimCard cell phone. You can see the list of countries where PENs are available here:

      You can order a Personal Extra Number when placing your order or later at any time by logging in to your account. Visit our Rates & Coverage page and choose any country to view all rates.

      If you would prefer for the caller to pay for calls made, we recommend they buy Speaklonger. Using this service would guarantee a connection to your OneSimCard mobile phone from the U.S and Canada for 20c/min and it is very easy to use without switching your LD carrier.

        or
      2. Set up auto-recharge in Recharge Settings Menu

20. How To Use Questions
    • Can I forward calls from my OneSimCard phone to another number?

      Yes. Your OneSimCard mobile number can currently be forwarded to EU, Canada, USA, Russia, Ukraine and Belarus numbers. It's 100% free to forward your OneSimCard phone number to many countries including to U.S. or Canadian numbers. Forwarding to some countries, as well as to satellite phones, will carry a forwarding charge as listed in the Rates & Coverage page on OneSimCard.com.

      To enable/disable call forwarding from your online account:

      Log in at OneSimCard.com and go to the My SIM Cards menu. Select your SIM card number and enable/disable Call Forwarding on this screen.
