Using more than 90 days Guide
Your prepaid SIM card will only last for 90 days upon receiving it and must be recharged monthly to continue service. After 90 days with no recharging, your SIM card will just be able to receive calls and texts for an additional ten-day grace period. After 90 days of no recharging, your prepaid phone number will be lost. Purchased credits are only valid for 30 days, and users must recharge their credits monthly to maintain service.
