Roaming

[Lium]

Hello, 

this is for iPhone XR, my allowance is set from zero to £10, roaming switched in and according to bt mobile guide 

If you have an iPhone 4S or newer, or are using iOS 8 and beyond, you can check the settings yourself.

1. Go to Settings
2. Select General
3. Select About

The "Carrier" should show as BT with the current version greater or equal to 18.1

If the Carrier is not showing "BT 18.1":

1. Go to Settings
2. Select General
3. Select Reset
4. Select Reset Network Settings

the problem is XR the carrier is not even on displayed - I have looked around if it hidden and it is not.
