If you have any overdue bills or have existing contracts with your current mobile service provider, the current mobile service provider will reject your port request which is made by the new mobile service provider. In such a case, you will not get a refund of the administrative porting fees. Kindly ensure that you do not have any bills overdue or contracts still in place with the new mobile service provider (on contracts, cross refer to Item 24 below).
For prepaid users, you need to know that all existing credit will expire upon successful porting and not be carried to the new mobile service provider. Therefore, you are encouraged to plan accordingly.
