Hi there. I have an ATT iPad 2 although currently have no data plan. I am traveling to England (Lake District) and Scotland this summer. I have three questions: 1) Can I purchase a pay as you go plan and micro sim when I get there with only my hotel address as a local address? 2) Which provider has the best coverage, especially in Scotland? 3) Is it necessary to activate my ATT data plan here in the US before I leave? Thanks so much for your help!
