i'd say go with straightalk and if you want to see the screen do NOT get an iPhone as they have some of the smallest screens out there. If you want a bigger screen then get either the S3/S4/Note 2/Note 3. I am currently using straight talk with the ATT LTE sim and an ATT variant S4 and cannot be any happier. phone does pretty much everything i want/need it to do. Just stay away from anything Sprint related as their coverage sucks with anything outside of city limits.
