Prepaid Samsung Galaxy S II coming soon to Net10
7

So, let's say that you are looking for a decent mid-range Android smartphone, but you also want it to be from a prepaid carrier. Net10 might have something just for you in the near future. We are talking about the Samsung Galaxy S II, which the MVNO will start offering soon for a price of $399. Sure, it seems a bit pricey, but that's because there is no carrier subsidy associated with the smartphone's purchase. On the bright side of things, Net10's unlimited plan costs $45 per month when purchased online, which doesn't sound like a bad deal.
