Just before entering the Monadhliath in 2010, I sought refuge in a phone box. Hmmmm, there were fake posies and it was now used as a regional library and bulletin board but I was still able to make a phone call to Challenge Control with my credit card so all was good. In years since, I now buy a pay-as-you-go phone when I enter the UK for £10 or so (unbelievable good value!) for my 4 Challenge Control calls & occasional calls from Husband.

As for UK coins, they are much too heavy to be carrying 'cross Scotland. Generous tips (?!) are left in my wake. Ha.

Thank you everyone, just remains to ask whether anyone knows how O2 stands up in the Highlands? It would save having to buy a SIM card etc etc...
Cheers

I'm Tesco Mobile, which is O2, I live in the Highlands aswell as being a Challenger, and I've always had a signal when I've wanted/needed one. Except in Culbin Forest...
