Very poor signal/mobile data when switching from O2 to EE

[Phil-g92]

I have a Samsung Galaxy S22 Ultra that I bought with O2 and have recently switched to EE. I have had next to no signal/mobile data since switching.

I have been in touch with tech support and they have had me turn on/off in aeroplane mode, reset the network settings, manually select EE network, factory reset etc. And nothing has worked.

I know for sure it is an issue with the phone itself as the sim works fine in a 4G MIFI router and a friend's EE phone also works. Does anyone have any idea on how to fix this before I cancel my EE contract?

Good morning @Phil-g92, thanks for reaching out to us via this!

This definitely sounds like an odd one if your EE SIM is working fine in other devices. 

Have you had a chance to test any other SIMs, from both EE or other networks, in your phone since noticing these issues?

No I don't have any to try at the moment. Must be an issue with the phone but I have no clue how to fix.

Cheers @Phil-g92, if you've already done a full reset on the phone then this would usually rule it out being a software issue. 

Did our team make sure that you had all the correct EE internet settings (APNs)?

Sometimes if you switch from another network, their details can still be stored in the phone and prevent you from being able to use mobile data.

Try a 2way SIM-swap.

Put your SIM in a known-working phone - what result?
