Receiving SMS / OTP hours later
For a couple of days, 3 lines of my Starhub phone numbers all having network issues (location S288416)
Signal weak, random drop, switching from LTE to H+, and worst case receive SMS / OTP late, in hours.
This only started recently, we had perfect experience with Starhub mobile network before.
This is NOT my devices issue, because my 3 lines of Starhub numbers are experiencing such issues and they are difference devices (Google Pixel and iPhone 12 and iPhone 8).
Reboot device does not help.
picture attached shows one OTP supposed to expired at 10:39PM but only delivered to me near 12AM.
In the meanwhile my phone shows signal weakly connected all the time!
