I'm traveling from the US. I will be carrying my phone with me. I want to use it in the UK to make calls and use a data plan. How do I go about it? Do I change my sim card to get a local # or do I contact my carrier (AT&T) to get a travel plan?
Last year, when I went to Ireland, I had an international plan with AT&T. However, their coverage was absolutely pathetic. I had a lot of problems with directions as the data was very sketchy. I then changed to Vodafone. As soon as I did that, boom! Full coverage. Will I face the same issue in the UK too? I will be driving around in Lake District, so, using Google Maps a lot. Hence, coverage is very important to me.
