The nine day countdown to register your pre-paid sim card has arrived.
The six month time line where you could register your sim cards ends at the end of this month. You still can get it done at any 7/11 Convenience store, Big C, Tesco or Bank Center apart from your phone store of course.
Your current registration status can be checked by dialing *151#
If you are not registered by the end of this month your sim card will be terminated automatically.
