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

6. Troubleshooting Questions
    • I am traveling in Saudi Arabia and can receive calls, but I can't make an outgoing call. What should I do?

      Local carriers in Saudi Arabia sometimes block standard OneSimCard outgoing calls. If this happens you need to either (a) enter a compatibility code into the settings of your phone or (b) initiate your call by sending an SMS message from the regular SMS menu (not the OneSimCard menu) of your phone.

      How To Activate Compatibility Mode:

      1. Open "OneSimCard" menu
      2. Select "Settings"
      3. Agree with message by pressing "Yes"
      4. Dial digits "802" and select "OK" (screen will show message "output channel is SMS")

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

      How To Deactivate Compatibility Mode:

      1. Open "OneSimCard" menu
      2. Select "Settings"
      3. Agree with message by pressing "Yes"
      4. Dial digits "801" and select "OK" (screen will show message "output channel is USSD")

      How To Dial Without Activating Compatibility Mode:

      Initiate your call by sending an SMS message from the regular SMS menu (not the OneSimCard menu) of your phone.

      To: 9146
      Message: 00 + Country Code + Number + 
      * is a star character located on the keypad

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

      To: 9146
      Message: 0018574440686
      After your SMS is sent wait 3-10 seconds. You will get a callback as usual and your call will be connected to the destination number.

      Note 1: You can't send this SMS from the SMS OneSimCard menu of the phone.

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

       

      There are no special instructions to receive calls in these countries.

7. Troubleshooting Questions
    • When I try to make a call, I get a message 'Call is modified and cannot be made'. What does that mean?

      Some phone models do not allow direct dialing with older OneSimCard SIMs sold before January 1, 2017.

      To get around this problem, you should try either of these methods:

      • Locate the OneSimCard menu on your phone. (Some phones have it in Applications.)
        Make a call using menu 'Call'.
      • You can also make a call by dialing directly *146*00 Country Code Number#
        For example, to make a call to the USA, you would dial *146*0018574440686# (do not forget to hit pound at the end of the number)

      * is a star character located on the keypad

      Other examples of how to use the *146* dialing prefix if necessary:

      • 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 (it is¬†a¬†star¬†character located on the keypad)
      • 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 prefix *146* and # at the end can be used from any phone. However, newer OneSimCard SIM do not require it and you should be able to dial codes directly, 091, 094, 095, 099 or 098XXXX*XX Talk.

      If you have an older SIM and the dialing does not work without entering *146*, please follow these simple instructions to remove the need to dial *146*:

      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.

      When dialed directly, some Nokia and other phones can display message: "Call is not allowed" or "Call is barred". Just ignore this message and wait for the ring-back for 10 seconds or so.


8. 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
      • 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 OneSimCard menu or *146* by following these simple programming instructions below.

      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
        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.

      9. Troubleshooting Questions
        • When I dial following your instructions it does not work. What's wrong?

          This answer applies to SIM cards purchased before January 1, 2017.

          Some phones, such as Samsung, some Motorola, Android and Apple iPhones, require special dialing instructions or simple OneSimCard settings menu changes in order to make calls.

          It is possible to make almost any phone entirely compatible, so you can call directly without using the OneSimCard menu or *146* by following these 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 or OneSimCard 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 Service Code option and follow instructions below:
            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.

              If for any reason after entering compatibility code, you still do not get a ringback or you get the ringback the first time you make a call, but second time it would not work, please enter code 802 into the Service Code window instead of 1101 as provided above.

               

              iPhone users can download OneSimCard Assist App from iTunes that will takes care of the iphones compatibility issues, except for removing the ringback.


              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,

              • To listen to voice mail *146*095# and press the TALK (or SEND) button

              The sequence *146* and # at the end can be used from any phone. However, most phones do not require it.

              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.
              Again, this troubleshooting advice might be needed only for older SIM cards.
