SIM Card LifeCycle
  • Your top up validity is based on the amount of your last top up. However, if your previous top up validity is longer than that of your last top up, it will follow the longer one. 
  • To check the status and validity of your top up, dial *1201# or go into the SmartNas app.
  • Smart reserves the right to withdraw the phone number and SIM card and to close the account of any subscriber who fails to top up their number within 90 consecutive days of the expiry of their top up validity. After the top up validity expires:

    • The phone number’s outgoing services will be blocked for 60 days.
    • If there is no top up within the 60 days, the phone number’s incoming and outgoing services will be blocked for 30 days, and any remaining main balance will be cleared. 
    • If there is no top up within the 30 days (a total of 90 days have passed since the expiry of the top up validity), the phone number will be recycled and made available to other subscribers.
