iPhone 14 pro signal poor

[Jonah1983]

Just transferred across from ee to sky. Phone number has ported over ok, but, I don't receive text messages from anyone now (iMessage works fine) and my data signal is dreadful, I've spent the last 2 days on 3G at best, the dreaded "E" has been seen a lot and even zero data signal numerous times. Sky customer support have basically just gone through a lot of "turn it off and on again" fixes with me, does anyone have anything else that may be more helpful?!? Thanks in advance!

You could try this, not sure if it will help:

Go to Settings > Mobile Data > Mobile Data Options > Voice & Data select 3G, wait one minute then change it back to 4G.
