So I have perused threads about unlocking phones and getting SIM cards on arrival to wherever you are as well as a few other options for keeping connected when out of your normal service area. They all involve multiple steps that I just don't want to have to deal with if possible. So here's the lowdown. Czech Rep, Germany and Switzerland (possibly Austria) over two weeks. I really want just data to be able to email when not able to find wifi. I won't be making phone calls and only occasionally texting. I am okay paying as I go for talk and text as it will truly be only as needed. I have a an iphone 4s and my service is with AT&T. My question is has anyone ever just added data temporarily for international with AT&T and how was it? It doesn't look much more expensive than me having to change SIM cards for each place I am going (unless I am looking at this all wrong, which has been known to happen) Thanks in advance for any input!
