300-Minute Prepaid Card (1 year)
This SIM-card contains 300 minutes of ISU to PSTN airtime, and is valid for 12-months from the date of activation. This voucher cannot be extended and minutes do not roll over. A SIM card with this option can be reloaded if the account is reset (you lose any unused minutes). The SIM-card can be converted to other prepaid plans at no additional cost. All unused minutes will be lost after expiration or upon conversion to the other account type.
