You mean that other connected apps work ok on carrier data while in the UK but not Google Maps?
That sounds very strange.
What happens when you try to use Google Maps?
Any error messages?
Anything useful here?
If you need to contact 48 support about this then see the link in my signature below or email them at support@48months.zendesk.com
But it sounds more like a phone/app issue than a 48 issue to be honest.
