1. How To Use Questions
    • What Is the Difference Between "Direct Dial" and "Callback Dial" calling?

      Direct Dial calling allows the caller to enter the international  call prefix, country calling code and telephone number and then be directly connected to the person they are calling. This is how you dial when using your regular mobile service. Direct Dial Calling is standard on the OneSimCard Europe & More, OneSimCard Universal and eSIM.

      Callback calling also allows the caller to enter the international  call prefix, country calling code and telephone number. After the called number is entered, the user immediately receives an incoming call connecting the user to person called. Callback is very simple to use and allows for low cost calling on the OneSimCard Plus and OneSimCard Expedition (formerly Data & Roam). Callback does not increase the connection time. It is the same as with Direct Dial.

2. 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.
          d when used with a OneSimCard.

      3. 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,
                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* 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.

               

               

          4. How To Use Questions
            • Is there any way to remove the callback ring after I dial a number?

              The newly offered eSIM, OneSimCard Europe & More and Universal SIM cards do not use the callback to make an outgoing call in over 70 countries.

              Currently, the mobile application to remove the callback on other SIM cards is not available.

          5. How To Use Questions
            • How can I dial '+' on my phone when making call?

              Note: You can always dial 00 instead of + when making outgoing calls. For example, to reach OneSimCard customer service in the USA you can just dial 001 617 3138888.

              You should consult the phone manual for this info. Different manufacturers have specific ways to access the '+' key, so make sure you know yours.

              Here are few known ways:
              • BlackBerry?ģ 6210: Press Alt (bottom, far left on keyboard) and the letter "I".
              • Bosch: Press and hold the star (*) key until the "+" sign appears.
              • Motorola: Press and hold the zero key until the "+" sign appears.
              • Nokia: Press the star (*) key twice in rapid succession.
              • Pocket PC: Pull up the keyboard, hit the <123> button in the top left corner, and select "+" from the resulting screen.
              • Samsung: Press and hold the zero key until the "+" sign appears.
              • Sony Ericsson: Press and hold the zero key until the "+" sign appears.
              • Treo 270: Press the blue button and then the "G" key.
          6. Troubleshooting Questions
            • I have an Apple iPhone. When I dial following your instructions it does not work. What's wrong?

              This reply does not apply to OneSimCard Europe & More SIM or newer SIM cards purchased after January 2017.
              Older SIM cards might require entering the compatibility code on your  iPhone.

              How to activate compatibility mode:

               1. Locate OneSimCard Menu.

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

              1. Open "OneSimCard" menu ( SIM Applications)
              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.


              We strongly recommend you to watch very short video tutorials for iPhone that will help you to understand how to make calls, SMS and data on your OneSimCard iPhone.
              If your phone is not Jail-Broken, you still can use OneSimCard Assist app available from iTunes. This app will help you to dial numbers properly by correcting mis-dialed numbers and will allow easy access to OneSimCard functions like checking balance, recharging your SIM, activating discounts and others.

              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 is for older SIM Cards. Newer SIM cards do not require entering any codes in iPhone or other types of phones.
          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 th *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. Rates and Cost Questions
            • Is there a 911 emergency number in Europe that can be used with OneSimCard service?

              Yes, in Europe the emergency number is 112. You can use 112 in Europe to report real emergencies to local authorities in the country of stay. The 3 digit number should be dialed directly without any additional digits in front of the number.
          9. 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:

          10. 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.
