I switched from Vodafone and had a strong 4 bars.
Now I have switched to idmobile and seriously regret it. Websites online all said excellent signal when I put in my postcode, I guess I have been lied to.
1 bar with -114 dBm. It isn’t my phone as my partner has the same strength on Three.
Why is it so poor?
In Settings (Android) for SIM card status it says ‘Mobile network state - Disconnected’. What gives?
