Inmarsat prepaid airtime vouchers will recharge or activate your IsatPhone SIM-card from SATTRANS.
Please make sure that you place your order for a new voucher at least three (3) business days before your account expiration date. We can't guarantee a timely recharge for vouchers ordered less than three business days before the expiration date.
All unused minutes on your existing Inmarsat IsatPhone prepaid account will be rolled over ONLY if the new voucher is applied to your account BEFORE the account expiration date.
Purchase a prepaid voucher here only if you have an Inmarsat IsatPhone prepaid SIM-card from Sattrans, as we cannot administer other providers' SIM-cards. If you don't have a SIM with Sattrans, you can purchase a new IsatPhone prepaid plan.
