You could always read a book like we used to before 3G came along

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.

Currently using:
Pixel 7a (O2 & Lyca), One Plus 6 (Sfr), iPhone 12 Pro Max (Vodafone)

I have upgraded my 3G SIM to 4G SIM. Put it on new 4G Phone, Power-off old 3G phone, and then Power-on 4G Phone. But it says no service. Network search says "SIM not authorised".

I have tried 3G Phone, powered-on again, then it still works. I do not think SIM swap have not done yet. It has been 4days since I ordered new 4G tariff.

Have you gone through the sim swap process or have you just put the 4G sim into the new phone expecting it to work? http://swapmysim.o2.co.uk/

I DO NOT WORK FOR O2
