Coming back into the UK after a holiday

[SoniaSh_2112854]

We are coming back to the UK after a holiday, we changed our phones so they would work abroad. 
Do we need to do anything to change them back so they work as they did before the hols? I can’t find anything in FAQs 😬😬

No, leave the APN as it is, your phones will still work here
