all worked well before port over to vivifi, im from starhub. and guess what. i have also port over my wife number (same from starhub) to vivifi. and she has no problem at all! and now i updated my profile sms contact in order to get the otp sms.Yes, you are right.
My initial thinking was that that they could be settings that you might have missed hence my previous comments, but it seems your insurer does not provide that.
At this point, you can only depend on email then. Probably you want to give feedback to them?
As not to derail this topic away from Vivifi, did the SMS OTP worked before you came over to VIVIFI? If so, maybe can talk to VIVIFI as well. Doesn't hurt to ask about this issue since it really affects your overall experience
yes. have emailed to both parties. and status is still pending.
