Hi all. So I'm heading to London in a few weeks and was wondering if anyone had recommendations in which payg SIM I should get for my iPad Mini. I already have Orange for my AT&T iPhone 4S but wanted LTE service for my iPadM. (I guess I should ask if the Verizon iPadM can even get UK LTE? I know it's unlocked.) Does Orange have good LTE/HSPA+ service or should I look into 3? I'm there for 10 days and will not likely bring my Air. We may also head to Edinburgh for a couple of days so something that works up there would be great as well. Secondary question: the SIM i have w/ Orange is a few years old and I've kept it active and still works but I've not been to London for a while. Do I need to exchange the SIM to get HSPA+ on the 4S? Thanks!!
