Simpel calling card validity time is 6 + 1 months
Your Simpel mobile number remains active for 6 months after the last recharge of €3. If you do not recharge your Simpel card with at least €3 (at one time) during 6 months (180 days), voice and other paid services will be temporarily restricted.
During the following month (30 days), you can only receive calls and messages. If you do not recharge Simpel with at least €3 during this time, the card will be closed permanently, and the number and unused calling time is lost. If you want to use Simpel again, you must purchase a new Simpel starter kit with a new phone number.
