Hi guys, I will spend almost a month in the US and have an unlocked iphone 4. So I need a prepaid plan with lots of data available - 100-200 MB is not an option. Here are the options that I found on the internet: 1) Simple Mobile - $50 - unlimited nationwide talk, text and 2G web Well, yes, they also offer speeds up to 4G for $60, but their support told me, that they don't support iphone 4, so i will be able to use only 2G. http://www.mysimplemobile.com/Simple-Mobile-Plan.aspx 2) AT&T GoPhone - $50 + $25 - unlimited nationwide talk and text for $50/30 days, or $2/day; 500MB for $25. I'm not sure if 500MB is enough for me though .... I definitely prefer "unlimited" data plan. http://www.wireless.att.com/cell-ph...ans/pyg-cell-phone-plans.jsp?_requestid=64530 3) T-Mobile Monthly4G - $70 - unlimited nationwide talk, text and 5GB high speed data, then 2G speed. For $50 you get 100MB high speed data, then 2G speed. The big question here is - can I use the 4G network with my german unlocked iphone 4? And here is my rating: Option 2) is not suitable for me, because I need a lot of data! Even if the 500MB were enough for me, the plan costs $75/month, maybe $100/month for 1GB. Option 3) is obviously better than option 1) - the same price, but at least the first 100MB are 4G. And if I want to - I can spend $20 more to have whole 5GB 4G traffic. So, I tend to the $70 prepaid plan from t-mobile. Could anyone tell me for sure, that they have 4G support for iPhones, especially iPhone-4? And, of course, are there any other options for prepaid plans? Thanks for any help!
