REGISTERING MY SIM ON A NEW PHONE

[REDROCK]

I have swapped the SIM from old phone (A Samsung Galaxy S24+) which has a broken display to a temporary Samsung S24. All the apps and data have come across Ok on the Wi-Fi however I cannot connect to the O2 network. The message is " Not Registered on Network". I have the username & password to log into MyO2 correctly but a confirmation text to my mobile is required to manage my SIM on my new phone. Because the network connection has failed I am unable to receive a text or make calls on my new phone. Is there another  way of confirming my log on to MyO2?

Unless the sim is damaged it should work, assuming the phone is in working order?

Have you inserted the sim correctly?

The easiest way to sort this and check things all in one place, is to go in store with photo ID and they will check sim and phone for you.

The phone is working perfectly on WiFi and I have reinserted the SIM a few times so it could be a faulty SIM. It was still working in the screen damaged old phone on bluetooth. Thanks for the reply.
