1. OneSimCard General Service 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

2. OneSimCard General Service Questions
    • Will my CDMA cell phone from Verizon or Sprint work overseas with OneSimCard?

      No, unless you have a "World Phone" from Verizon or Sprint that is dual-mode CDMA/GSM. Most current smart phones including iPhones 4S, 5 and 6 offered by Verizon, Sprint, N-Telos and other CDMA carriers have GSM radio and will work when traveling abroad.

      CDMA-only phones will not work with OneSimCard service. OneSimCard service requires an unlocked GSM capable phone (for example, all AT&T or T-Mobile phones are GSM). Some domestic carriers such as Verizon and Sprint use CDMA technology, while most of the rest of the world uses GSM. Check with your wireless provider or phone manual if you are not sure if your phone is CDMA or GSM.

      Verizon and Sprint now offer iPhone 4S, 5 and 6, as well as some models of Samsung Galaxy 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 most probably they will do this for you. Once they unlock the phone you can use OneSimCard SIM when traveling abroad. 
3. OneSimCard General Service 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.

4. OneSimCard General Service Questions
    • Which phones are compatible with OneSimCard service?

      Any unlocked GSM phone is compatible with OneSimCard Europe & More SIM that does not require any special dialing instructions.
      For Plus and Data & Roam SIM cards, most GSM unlocked Tri-band or Quad-Band phones are compatible with OneSimCard service.

      Older Verizon & Sprint dual-mode CDMA/GSM "World Phones" such as BlackBerry (Bold, Curve, Tour, Pearl, Storm, 8830); LG (Fathom); HTC (Touch, Ozone, Imagio); Samsung (Saga, Intrepid, Renown), are compatible with OneSimCard, however require special dialing instructions shown here.

       

      All iPhone modes and Androids GSM Phones are compatible with OneSimCard.

      Some phones will allow calling only from OneSimCard menu. Some phones will allow calling directly, but with the use of prefix *146* as described in the user guide.

      Some phones such as Samsung and some other brands require dialing a specific prefix *146* in front of the dialed string when used with a OneSimCard.

      For example, calling to USA: Dial *146*0016175551212# and press the TALK (or SEND) button
      * is a star character located on the keypad
      • To check your balance dial *146*099 and press the TALK (or SEND) button
      • To add funds dial *146*098XXXX*ZZ and press the TALK (or SEND) button,
        where XXXX - 4 last digit of your credit card on file, ZZ - Recharge amount
      • You need to press * on your phone in the above dialing sequences
      • Activation of voice mail *146*091 and press the TALK (or SEND) button
      • Deactivation of voice mail *146*090 and press the TALK (or SEND) button
      • Check number of messages in Voice Mail *146*094 and press the TALK (or SEND) button
      • To listen to voice mail *146*095 and press the TALK (or SEND) button

      The sequence *146* can be used from any phone. However, most phones do not require it.

      It is possible to make almost any phone entirely compatible so you can call directly without using the OneSimCard menu or *146* by following the simple programming instructions below.

      How to activate compatibility mode:

       

      1. Locate OneSimCard Menu.

       On iPhones it is called SIM Applications menu and is located under Settings- Phone menu

               On Androids it is called SIM Toolkit app and it looks like one of the apps

      1. Open "OneSimCard" menu ( SIM Applications, SIM Toolkit, STK)
      2. Select "Settings
      Newer SIM Cards: Select Compatibility option and make sure "On" is selected
      Older SIM Cards: After selecting Settings:
      1. Agree with message by pressing "Yes"
      2. Dial digits "1101" and select "OK" (Screen will show "CC OptionX: ON" message)

      Bear in mind that if you have powered your telephone down, and have removed and reinstalled the battery, you will need to follow the programming steps outlined above, again.


      Here is an incomplete list of compatible mobile phones with notes about specific OneSimCard compatibility. We are constantly working on updating this list. Please share with us your experience about your specific wireless phone model and we will share this information with others.
5. OneSimCard General Service Questions
    • Can I keep receiving calls made to my regular cell phone or landline numbers while traveling abroad?

      Yes, you can easily forward calls from your regular cell phone number, home phone, office, etc. to your OneSimCard phone while you're abroad!

      Your OneSimCard international SIM card comes with both a European and U.S. number. To forward your regular U.S. numbers to the SIM, just set them to forward to the U.S. number that's included with your SIM card.

      You can also order unlimited Personal Extra Numbers (PEN) - Local or Toll Free - in many different countries, including USA, Canada, UK, France, Italy and Spain. For example, if you work or live in the UK and want to keep receiving calls made to your regular UK numbers, just add a UK PEN to your SIM card and set up call forwarding to that new number.

      Calls received through a PEN will be charged an additional 20c/min to the incoming rate of the country you are in. The exception is calls received through a UK-Mobile PEN which is only charged an additional 25c per call.

      Please Note: Your subscription to a Personal Extra Number starts the moment your order is shipped. If you do not need your PEN to be active right away, you can always wait and order a PEN later at any time by logging in to your account.

      Different carriers use different ways of programming call forwarding. Below are instructions to setup call forwarding with various US wireless carriers. We urge you to test the call forwarding a few days prior to your trip, and to call your US wireless carrier for assistance if needed.

      Alltel, Sprint PCS, Verizon Wireless, Nextel, Cricket Wireless

      To activate Call Forwarding:

      1. Press *72 on your cellular phone.
      2. Enter your ten-digit Second Personal OneSimCard phone number (area code + telephone number).
      3. Press OK/Send (a tone will confirm that Call Forwarding is active).
      * is a star character located on the keypad

      To deactivate Call Forwarding:

      1. Enter *720 on your cellular phone.
      2. Press OK/Send (a tone will confirm the deactivation).

      T-Mobile and AT&T Wireless GSM phones

      To activate Call Forwarding:

      1. Press *21* on your cellular phone.
      2. Enter your ten-digit Second Personal OneSimCard phone number (area code + telephone number) followed by the # key.

      To deactivate Call Forwarding:

      1. Enter #21# on your cellular phone.
      2. Press OK/Send.

      Please note that Sprint and Nextel may charge an extra 20c/min on forwarded calls.

6. OneSimCard General Service Questions
    • Can I forward calls from my OneSimCard phone to another number?

      Yes. Your OneSimCard mobile number can be forwarded to almost any other number around the world! 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. There are a few exceptions where calls can not be forwarded to certain numbers.

      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.

      To enable/disable call forwarding from your phone:

      Dial *146*081*XXXXXXXXXXXXX# and press Send/Talk (where XXXXXXXXXXXXX is the forward-to number in international format: 00+countrycode+number)

      Newer SIM cards use *81* instead of *081*

      Example: to forward to U.S. number 1-617-555-1212, dial *146*081*0016175551212# and press Send/Talk.

      If you get an "Unknown Format?" message, dial *146*81*0016175551212#

      To disable call forwarding, dial *146*080# and press Send/Talk. If you get an "Unknown Format?" message dial *146*80# and press Send/Talk.

7. OneSimCard General Service Questions
    • What phone numbers are included on the global SIM card?

      Starting April 19th, 2016, our OneSimCard international SIM card comes with two phone numbers: European (Estonia) and U.S. numbers. For Canada Customers it is European and Canadian numbers. For Australian customers it is European and Australia numbers and for UK customers it is Estonia and UK Mobile numbers.

      The primary European number is based in Estonia (country code +372). Estonia is a member of the European Union and one of the most high-tech and entrepreneurial societies in the world, especially when it comes to telecommunications.

      You can choose your area code for the free 30 day U.S. and Canada PENs. Australia and UK numbers are randomly assigned. You can choose to activate your free PENs when you activate your SIM card or at a later date. Once your free PEN has been activated, it will be active for 30 days unless renewed monthly or yearly for a small cost. If you would like to choose your own U.S. or Canada, Australia or UK area code or a Toll Free number, you can also order those numbers separately.

10. Troubleshooting Questions
    • I have a Samsung phone. When I dial following your instructions it does not work. What's wrong?

      Some phones such as Samsung and some other brands require dialing a specific prefix 146 in front of the dialed string when used with a OneSimCard.

      For example, calling to USA: Dial *146*0016175551212# and press the TALK (or SEND) button
      * is a star character located on the keypad 
      • To check your balance dial¬† *146*099 and press the TALK (or SEND) button

      How to activate compatibility mode:

        1. Locate and Open "OneSimCard" Menu. ( It could  be displayed as STK Menu)

              2. Select "Settings"

        Newer SIM Cards: Select "Compatibility" and make sure "On" is selected
