Apple iPhone 5 review - Pocket-lint
Looks like the new iphone requires a new smaller sim card...At a glance the SIM card slot looks the same as well, but it isn't. It's actually smaller and that's because the phone now features the smaller format nano SIM, rather than a micro SIM. Yep you'll have to order a new SIM for your iPhone 5 and, as the name suggests, it's tiny.
