Fold 4, no signal

[Beershark]

Hi all,

Have had a Fold 4 on EE for around 18m, always been a decent signal.

A month or so ago, the signal weakened... I took a domestic flight and when I landed, flight mode off .... no signal in a known good area.  Tried restarting etc., no good.  Wi-fi was fine for calls etc.

Tried searching for network manually, only one network Three came up occasionally then nothing.  Tried restarting with and without sim, reset, clear cache.... nothing worked.  Sim is fine, worked in another phone and other sim in, no good.

So, I reset it once again, left it plugged in charging (it had maybe 40% charge) and switched off  for a few hours and it worked on restart.

Been fine until today, randomly on a drive, at my destination it had stopped.

Before I reset / return if required, any other ideas maybe?

Thanks

EDIT:-

Tried clearing cache
Tried switching to flight mode on / off several times
Tried resetting all connection settings
Soft reset
Starting in "safe mode" I still have no signal.  Not on EE, and no other networks found.
Full reset done, still the same so sending back to Sammy.

Exactly same issue

It turns out that unbeknown to me, EE had mistakenly BLOCKED my IMEI number.  They should have blocked a different phone on my account.

Turns out, I usually use the phone at home and was working fine on Wi-Fi calling at home, airport etc.

Did anyone find a fix for this I have the same issue?

Does yours work with wi-fi calling?

[Lordamercy]

Yes mine works well with WiFi. But it's definitely not blocked as it intermittently will get signal and also I've checked the imei online and it's not blocked or blacklisted. But it sounds like the exact issue you experienced so I'm really confused now.

Have you tried both sim slots?

Or another sim in your phone?

[Lordamercy]

Yeah it only has one sim slot and esim and tried the sim in other phones and its fine. And also other phones on the same network. It must be an antenna issue of some sort..
