21. How To Use Questions
    • How do I make a call using OneSimCard global cell phone service?

      To make a call:
      • Dial 00-CountryCode-AreaCode-Number and press the TALK/SEND button.
        Example: To call OneSimCard Support in the USA you would dial 00 1 617 3138888 and press TALK/SEND.
      With Europe & More SIM that does not use the callback to make a call, you will just get connected.

      With OneSimCard Plus SIM or Expedition (formerly Data & Roam) SIM:

      After pressing the TALK/SEND button you will see a variable message on the screen (for example 'Wait for call') which you can ignore and your phone will ring back in a few seconds. Answer this ring as you normally would answer any incoming call. Your call will then be connected.

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

      We allow moving balances from one SIM card to another in the following cases:
      • Corporate Accounts - anytime.
      • Individual Accounts - only when a SIM card is lost or stolen. The remaining balance from your lost or stolen SIM card can be transferred to another SIM card on your account or you can order a new SIM card if you would like to keep your original European number from the lost SIM.

      Yes. All unlocked iPhones' Hotspot feature works with OneSimCard SIM.

       
      There are a few settings to make sure for this to function properly on your iPhone:
      1. Settings - Cellular - Cellular Data - ON
      2. Settings - Cellular - Data Roaming - ON
      3. Settings - Cellular - Cellular Data Network - Cellular Data - APN = APN will be set automatically

      After turning the Hotspot on, you should stay on the Personal Hotspot screen of your iPhone for SSID of your phone to show up on other Wi-Fi devices, so you can get connected. After you connected to the Hotspot, you can leave the screen. Alternatively, you can always use Bluetooth or USB connection to provide the internet access from your OneSimCard iPhone Hotspot to your other devices.
