Hi, I have recently ported from M1 to Starhub and facing the same issue too. Contacted customer services twice and no solution provided yet. May i know what is the solution for this as i am not able to do online banking at all.
Facetime and iMessage was automatically switched to my alternate number when i ported over. So need to make sure that these are linked back to the ported number or removed. That was how i got the OTP to work for me again, hope this helps.
