No service in the house

[Rmcd74]

I came home from holiday 17/7 and trying to use the iphone 14 pro max to make calls,it doesnt connect to make outbound calls or receive calls as it goes between 3g,no bars or an E where the 5g should be

i was able to use the mobile before holiday without any issues and now its become an issue,,if i go outside the house it can be 100 yards before a signal appears so is it something to do with the mast as ive already been told that the service in my area is fine

Give this a try:

Settings > Mobile Service > SIM Applications > Make sure this is set to Home.

If you have the Sky Menu app then you can use this instead.

I go to the menu 

i click roaming and its set to >home

is this correct
