I am looking for a T-Mobile pay-as-you-go micro sim card. I want to use their $3/day unlimited text/talk plan on my next trip to the US (Vegas), rather than paying my Canadian provider $50-$100 for 5 days of international talk/text/data. Of course, I have an unlocked iPhone 4S. However, the only T-mobile pay-as-you-go micro sim cards I can find on eBay are being sold from the UK. When I tried to buy one from the US T-Mobile website, it wanted me to sign up for a contact. Anyone had success buying one on eBay that worked? Did yours come from one of these many UK sellers? Or did anyone find a decent deal from another US provider, and pick up a pay-as-you go micro sim online?
