I dropped my simple little Samsung 225 cell phone in water, and
since then several functions are not working well. (For instance, if I
turn the phone off, the only way I can turn it back on is to take the
battery off and then reinsert the battery.) However, the phone is
still serviceable, but T-Mobile wants to charge me and arm and a leg
(About $200) for this $25 phone. Therefore, I am wondering whether I
can buy the phone on the market, and then insert my old sim into the
new phone. In such a case will the new phone still connect with
T-Mobile's service. Or, is there possibly another work-around where I
can get a completely working new phone and avoid being overcharged by
T-Mobile.

Thanks for any help,

JD
