IMHO.Has anyone experienced delays receiving SMS? I had to re-authenticate a bunch of apps, and the OTP SMS for all were delayed well past expiry. And when they did arrive it was all at once for multiple apps/attempts. I even switched phones to exclude phone issue. I live in top-floor HDB, surely location's not an issue?
If you mobile don't have speed issue, then it is unlikely because of your location.
AFAIK, usually living on the upper floors of super tall HDB will have issues because the base station coverage is usually on the ground.
P.S. I have TPG but don't use it for OTP.
