Wow, just found this out by scanning the net, but if you've got the Treo 700w, you can call Verizon and ask them to add the PDA SMS 2000 Allowance (code #70246 if they can't find it). This will give you up to 2000 SMS messages from Wireless Sync without cutting into your regular TXT message allowances!

Hope this helps someone like it helps me
From what I was told, you still have to have a TXT messaging plan if you want to use regular text messaging....can anyone confirm or deny this?
