How often do I need to recharge my OneSimCard account?
For Universal E, Expedition E, eSIM World E, eSIM Asiania, Plus, Europe & More, & Standard SIM Cards, the international SIM card phone number and account will expire if no outgoing usage is made for 12 months. The outgoing usage could be any of the following: Call made from the phone, SMS sent from the phone or any Data Usage.
Personal Extra Numbers will stay active as long as they have been funded properly.
The SIM card balance is valid for 10 months. The balance will continuously roll over to the next 10 month period provided that at least $25 is added within 10 months after the last recharge.
If the balance expires, the service can still be used after a new recharge of the SIM card.
For DataMax Plastic & DataMax eSIM SIM Cards, the SIM card and account will expire if no outgoing usage is made for 12 months. The outgoing usage could be any of the following: Call made from the OneSIM VoIP App, SMS sent from the OneSim VoIP app or any Data Usage.
Personal Extra Numbers will stay active as long as they have been funded properly and the SIM hasn’t expired. If the SIM card expires, but then is restored ($10 Restoration Fee applies), the PEN will be re-attached to the SIM card, as long as the PEN hasn’t expired based on the time period for which the PEN was purchased.
The SIM card balance is valid for 10 months. The balance will continuously roll over to the next 10-month period provided that at least $25 is added within 10 months after the last recharge.
If the SIM card balance expires, 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. So, to keep the SIM active you need to either keep a balance on the SIM or an active data package.
An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.

If your phone or SIM card is lost or stolen and automatic recharge is on, this could be a serious problem.
To prevent this, log in to your account and activate the option to block your service immediately after you notice your phone or SIM card is missing. You can find this option in the My SIM Cards menu. Your OneSimCard service for this SIM card number will be instantly blocked. The remaining balance on your lost SIM can be transferred to another SIM card on your account or you can order a replacement SIM card if you would like to keep your phone numbers from the lost SIM. However, the existing data package can’t be transferred to the new SIM card.
Alternatively, you can contact customer service online or call 001-617-313-8888 for assistance.
