most of them are sim only and sooo sooo soo cheap. My phone plan is on the expensive side, and i could change it if i want but it suits me. i'm paying 27$ for $850 worth of calls, unlimited text and 3 gigs. I never even come close. I could swap down to $600 worth of calls, unlimited text and 1.5 gig for 18$ but i don't think thats enough data for me. Compare that with what i was paying for AT&T back in NYC of over 90$ for 700 minutes, 1500 texts and unlimited data. SO happy.
