With a pay as you go phone, you just purchase the phone at a department store. When you need minutes, you purchase a prepaid card; you scratch off the back to get an authorization number which you enter into your phone and the minutes will added for you. Some companies, such as Boost, TMobile, Net10, and Metro PCS offer monthly unlimited plans for a set monthly fee. Metro PCS phones are usually more expensive than others.
There are a number of pay-as-you-go cell phone plans that will work in this instance. Virgin Mobile is a great solution for low cost plans that do not involve contracts.
Other cell phone companies include Verizon, Sprint, T-Mobile, and metroPCS. My personal favorite is Virgin Mobile, their prepaid plans are pretty reasonable and the phones that they work on aren't too shabby.
Only if the T-Mobile phone is unlocked. If the T-Mobile phone is still locked, only T-Mobile SIMs will work.

No. Sprint uses CDMA and PCS technology, while T-Mobile uses GSM, so the Sprint phone would be incompatible with the T-Mobile network. Plus, Sprint phones are generally locked to Sprint anyway, so you couldn't use it even if T-Mobile offered CDMA.
