Hi,
I sometimes have to switch my sim card to another network because I can't get phone reception in one of my properties using Plusnet, so I use a PAYG SIM.
I recently got an iphone XS and I've had no network since I swapped it back.
I saw another post on here with a similar problem and tried the solution suggested there but the setting mentioned don't seem to exist. Removing the SIM and reinserting it and restarting the phone don't seem to work.
I'm at a loss.
