I can send text messages, but my 2FA ones aren't being received on my phone.

 

I've tried the following:

  • Turning WiFi calling on and off.
  • Toggling airplane mode.
  • Restarting my handset.
  • Getting the codes resent.
  • Checking the SMSC details (all correct).
  • Cleaning my SIM card.

None of that worked.

 

After several minutes, the codes came through in a batch of 10 (!) - however the latest codes still haven't come through.

 

Any other suggestions?

If the guide here doesn't help Guide: Text Message Tips (not sent or received) 

Contact O2 Guide: How to find help & contact O2
