T-Mobile
T-Mobile offers numerous pre-paid plans including monthly, daily and pay-as-you-go options. You can also purchase smartphones directly from T-Mobile even if you just want a pay-as-you-go option.
AT&T GoPhone
Pickings are slimmer at AT&T, which offers prepaid under the brand name of GoPhone. Plan options are not bad, however, and include monthly, daily and pay-by-the-minute options.
Unfortunately, there are not any affordable smartphone options sold for pre-paid users. You’ll want to look at another carrier if you want a solid but inexpensive pre-paid smartphone.
Verizon
You’ll only find monthly and daily pre-paid plans at Verzion, and if you go for the monthly unlimited or daily plan, your phone selection is reduced to “basic phones” – either flip-phones or feature phones. This is obviously not going to be acceptable to many geeks.
However, you’ll be paying for a monthly minute allowance regardless of how often you use them. If you want to go pre-paid because you don’t use many minutes or much mobile data, these plans aren’t going to save you any money.
Boost Mobile
Created specifically as a low-cost, no-contract carrier, Boost Mobile offers a number of plans with monthly, daily and pay-as-you-go options. However, the pay-as-your-go and standard monthly options lock you into basic and feature phones. You need to go for a daily or Android/BlackBerry monthly plan to obtain a smartphone.
Unfortunately the phone options aren’t going to blow you away. There’s only a few smartphones to choose from regardless of plan.
Virgin Mobile
This low-cost carrier only offers no-contract monthly plans. Virgin Mobile’s PayLo plan is the least expensive, offering 1,500 minutes for $30/month, but the phone choices are terrible.
If you go with a regular plan, however, you can buy some of the best value-oriented Android phones on the market.
