My phone has randomly started to say no service whenever I’m out of the house, and at home it says iD WiFi Call but with no signal bars. I have tried turning it on and off and removing the SIM card and putting it back in. I have the latest iPhone software update and no carrier update is available on settings. All my bills are paid and up to date.

Please could you try manually selecting the network by doing the below:
iPhone: Go to Settings -> Mobile Data -> Network Selection. Toggle "Automatic" to off and select "iD" from the list that comes up.
Let us know how you get on with this?
