We are here to help you get answers to your questions about OneSimCard phones and services.
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-1Â 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.
