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

[Sriracha92]

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 do the following,

1 - reset network/general settings

2 - turn on/off in aeroplane mode

3 - manually select EE network

4 - factory reset 

5 - clear SIM cache

6 - try different SIM slot

7 - replace SIM

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? My phone was working fairly well prior to this on 02.

Hi, maybe you need to replace the physical sim with an esim.

[Sriracha92]

I've also tried esim. Kinda confused why this would be the case

[Blessed4life]

Just an option, you didn't say you tried, the only other option would be to book it in to Samsung to have a look, you never know they might implement a software update to fix the issue, it's worth a try.

[Sriracha92]

I meant I'm confused why it wouldn't work from O2 to EE BTW not your suggestion lol. Yeah, I might go to Samsung to see if they can fix maybe

[Blessed4life]

🤣 A misunderstanding on my part.
I think Samsung would be the best option considering all the things you've already tried.

You have poor connection anywhere you go with EE sim or just at home 

[Sriracha92]

The connection is poor elsewhere too. It doesn't work at all at home, but can work slowly in other locations. But the same SIM works perfectly at home in a MIFI router

Does EE have generally good connection in your area? Also, contract or pay as go? 

[Sriracha92]

Yeah EE has very good connection in my area, working for friends, neighbours etc for years. And it's contract
