Yes, the most important party which people should be contacting after changing mobile providers is their BANKS.
They'll make the necessary change for the gateway to send your security TACS/OTP out
glad it work for u..
unfortunately for me though, it doesnt.. the banks and services feedback to me that there's no way they can change the gateway for individual phone number
and its been 2 months since i ported into Tunetalk, the TAC/OTP issue still persist regardless of which parties (TT, banks, services, etc) were trying to assist me
as i couldnt stand it anymore, i ported out..
guess what, all the needed TAC/OTP were received accordingly on the very first day i successfully ported into the other telco.. without needing the 3-7 days of 'cooling period'.. without the need to inform anyone as well
therefore, i noticed that the big 3 telcos (or 4) are quite consistent in successfully delivering TAC/OTP (regardless of prepaid or postpaid) when compare with MVNOs
i came across from other threads regarding certain portion of users facing TAC/OTP issue and most of them are on MVNOs
