If I was you, I would not get this phone. I looked into getting it a few years ago, the phone is that old. I did not get it because I read that the phone likes to crash alot and loses info. Also it is a pda phone which means that you have to pay an extra $30 a month for internet and it does not matter if you want it or not, if you do not pay for it, you cant text or anything on it. Look into the new matrix, propel, slate or my personal phone I have now, the quickfire. They all are "dumbphones" unlike your treo which is a smart phone. They all have keyboards and some have touch screen! Those phones do not require an internet package and yes, you're texting package will work on all those phones. If I was you, do not get the Treo. I hope I helped.
