Hi I'm from Mexico and I have a factory unlocked Inspire 4G which I use in my country and works perfectly fine. I will be going to the states for a couple of months so my plan is to get a prepaid sim card to be able to use my phone... I really really want a "voice,text,web" unlimited plan, so my biggest concerns are: 1 which carrier is the best to get my unlimited plan? 2 will I be able to use the data from that plan (I've seen others posts and apparently ATT gophone doesn't let you use data whit this kind of smartphone?) 3 I've been searching and found that t-mobile has monthly 4G plans I'm willing to get the $70 monthly 4G plan as long as I know for sure I will be getting 4G speeds and not simply 2G 4 if I get the monthly 4G will I be ableto use my phone as a WiFi hot spot? I'm determined to be able to use my phone while I'm in the states or should I just buy a prepaid phone (which I really want to avoid) So please any advice will be really appreciated Thanks in advance for taking the time!
