12. 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.
13. 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.

14. How To Use Questions
    • How do I make a call within the country I am currently located?

      You should make any call the same way as if you were making an international call.

      For example, you are in France and need to call Paris:
      You should dial 00331XXXXXXXX. Please note that you should not dial 01 for Paris, but rather just 1 after country code 33, because Paris' code is 1.

      Dialing 0 in front of 1 is required when making a regular long distance call within France to Paris. However, when making an international call or OneSimCard call, 0 is omitted.

      For example, if you are located in Italy and need to call Rome:
      You should dial 003906XXXXXXXX, as Rome's code is 06.

15. Troubleshooting Questions
    • I have an iPhone and am receiving charges for SMS sent to a UK mobile number 447786205094. Why?

      This is a known issue with Apple's Facetime and iMessage applications on Apple iPhone  devices. We recommend disabling Facetime and iMessage so it will not be able to automatically send SMS to this 447786205094 number. Any SMS sent to this number automatically by your phone can not be refunded by OneSimCard. Additional questions regarding iPhone applications and how they communicate should be directed to Apple Support.
      You can learn more on the Apple Support web site:

16. Troubleshooting Questions
    • I can't send SMS from my iPhone

      There is a known bug with iPhone phone book. If you are trying to text to a contact that is entered in the phone book, and the contact is not entered in proper international number format, the SMS will not go through even if you just enter the number in the SMS menu directly and properly. 
      Please edit the record in the phone book to be +CountryCode_Number. It needs to have the + character in front, which is an equivalent of 00.

      You will also need to delete all recent attempts to send SMS to this number from the Messaging menu. It should be no conversation or attempts to send SMS left in the phone to this number.


      We understand that this is very frustrating, but do not know why Apple will not fix it. This problem affects only Apple phones.

      Example: for US Number 1-617-600-8250 you should have entered in the address book: +16176008250
      Delete existing text conversation after fixing the phone book record. 
      You can always test your SMS by sending SMS to OneSimCard Support number +16176008250 from your OneSimCard phone. This will create an automated ticket in the system and you will know if the message was delivered or not. You will be charged regular SMS rate for this message.

19. 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.

20. OneSim VoIP
    • When making an outgoing call how do I select which way the call should go: through regular roaming or through OneSim VoIP?

      To make an outgoing call using OneSim VoIP, you need to be registered on a Wi-Fi network and have the OneSim VoIP app running on your phone. You should make the call using the OneSim VoIP app dial pad. To make a call the regular roaming way, you should make a call from your regular phone dial pad.
