where can you get cheap phones for t-mobile without a plan

get a prepaid.
thats the only option.

T mobile has the best prepaid plans. I gave mine to my daughter but used to get 1000 minutes for 100 bux and for every 100 bux you got 250 bonus minutes...1250 minutes for 100 bux. Last for 12 months and as long as you buy more before the 12 months the unused minutes rollover. I wish ATT had a plan like that. The downside is you will have little or no service if you are not in a city or close to a major interstate highway. I lost service 3 miles from most interstates unless I was at a very high altitude or in a city. Not a small city..a real city.

Ebay, or i'll sell you one.
