One of the troublesome issue faced by prepaid user is the deactivation of account due to inactivity of reloading prepaid credits. However, TuneTalk now allows user to extend their mobile number validity for one year at RM10.
If you are looking for extending your prepaid number validity, simply send “EXT” to 2222 and you are done! However, your account balance must equal or exceed RM33 before requesting extension of validity.
