47. 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, Univesal and eSIM World that do not use the callback to make a call, you will just get connected.
       
      With OneSimCard Plus SIM or Expedition (formerly Data & Roam) SIMs:

      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.

      If you are unsure about how to properly dial an international number, follow this link for detailed country by country dialing instructions.

      For Physical 3-in-1 DataMax, and DataMax eSIM cards, you can place calls using our low cost OneSIM VoIP service. OneSim VoIP costs much less than traditional voice roaming.

48. How To Use Questions
    • How do I prevent the service from expiring?

      The OneSimCard phone number has no expiration, provided you made at least 1 call or sent an SMS once every 12 months.

      However, the funds on the SIM expire 10 months after your last recharge. The minimum recharge amount is $25. You can keep the balance from expiring by simply recharging at least once every 10 months. If you let your balance expire, then all you need to do to get the service up and running again is to log in and add funds to your SIM card. Automatic recharge will be canceled if you let your funds expire.

      NOTE: For Physical 3-in-1 DataMax & DataMax eSIM SIM cards, if the SIM card has no balance, the SIM will expire and be removed from the account after 7 days, unless there is a data package currently active on the SIM (not a future activation). If there is no balance on the SIM and the active data package expires, the SIM will expire 7 days following the expiration of the active data package.

       

      An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.

       

49. How To Use Questions
    • Do I need to change any settings on my phone when going abroad?
