71. eSIM

    • Can I use Facetime, WhatsApp, Telegram, Discord, iMessage, and other messaging Apps with eSIM?

      Yes, you can use your messaging apps with eSIM World, which now offers a mobile number ID. 

      For DataMax eSIM, you can use these Apps as you already do. Please ensure your messaging account is already setup with your primary carrier’s phone number because you cannot sign up for these services with the DataMax eSIM number.

      Additionally, the eSIM data service can be used for the actual data part of your communications. So, when you are installing eSIM on phone, you can select the Primary service for Facetime and iMessage and then if your selected eSIM to be your primary data service, the communications will go over eSIM mobile data.

75. 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.

77. 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.
78. How To Use Questions

    • Can I check my Voice Mail from a phone other than my OneSimCard phone?

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.
