which telco and plan have most value for $ prepaid sim card for 2 weeks usage?
wow..so meaning using Iphone 5 or other older phone will not be able to use the data service??
Please remember - if you are using LTE band (AKA iphone 5 or newer devices), US LTE frequencies are different. In this case fallback will be on 3G.
But you'll be lucky to get 3G data on prepaid card. Last May Tmobile's prepaid data sims were limited to EDGE coverage in Bay Area.
How do u get hold of the T Mobile Prepaid cards? Do u buy online or buy from airport?
just walk in any AT&T store and buy, its 60USD for 30 days i think. went last aug.
for the sim card, i didnt check if theres nano sim, but there is micro sim, i brought 2 phones there that time.
can I confirm that there's no GSM in States? I have an older phone that only have GSM..so it will not work in States?
I think this is fixed now: the problem is that T-Mo's 3G network wasn't compatible with the iPhone. They've rolled out their LTE network now, which is iPhone compatible, so you should be fine (though if you find this isn't the case, let us know).
