A Purchased SIM comes with a lifetime of 12 months. A Euro 25.00 call minutes top up will extend the lifetime of the SIM for another 6 months. Accordingly a Euro 50.00 call minutes top up will extend the lifetime of the SIM for another 12 months, and Euro 100.00 will extend the lifetime of the SIM for another 24 months. Regardless of usage the SIM will stay alive until the lifetime ends. If the lifetime ended the SIM can be reactivated within a period of 180 days and any unused credit from your previous top-up will be carried forward. The reactivation charge is Euro 9.95
