Have a sprint phone which you done have what to do with because you done want to start a new contract?
Check out this web site i found (actualy the only service i found that uses sprint phones)
its called Ting.com
its very interesting the way it works and it has many benefits
the way it works is you pay for what you use
they have like 5 or six plans for each talk, text, and internet and you pick whichever you want
now if you use less they bump you down to the lower package and if you use more they bump you up, NO EXTRA FEES
its pritty cool, actualy when i spke to them they sayd to just put everything to the lowest package and they will bump be up to what i use,
now you pay per line, you can have as manylines as you want and the minutes are pooled
(so for example if you have a family member coming in for a monthmjust add a phone for $6 and at the end of the month cancel for free and it uses the minutes in your account)
some of the benefits are
no contract
great customer service
use your sprint phone
great deals
free picture mail
etc
check it out yourself on their web site!
USE THIS LINK FOR $25 CREDIT! (thats practicaly a free month)
