Returned from France to UK yesterday ( this may or may not be relevant). Roaming had been left switched on and worked, but I did not send or receive any texts or calls, just wifi and Whatsapp. Tried online banking today which required a code text to be received. Nothing. Tried another bank, same problem. Tried to log on to My O2, need to re register, we will send a txt code to your phone. Nothing. Submit a query on O2 network checker ( this may also not be relevant) But within 5 minutes all the texts from today and a voicemail from yesterday (2 hours after I arrived in UK, so not a local problem) suddenly appeared. Whats going on?
