says no service -SOS only. Help pls? My Palm Treo 650 is originally a Cingular phone that I bought a couple years ago. I decided to switch to T-Mobile yesterday since I hadn't had real phone service for awhile(been using prepaid/go phone) Well the sim card I had in my go phone from a couple years ago works still perfectly with my Palm Treo. But, when the salesman at T-Mobile tried to put in a T-Mobile sim card we kept getting the message "no service-SOS only" He had already lied about my old sim card no longer working and that I need to buy a new phone from T-Mobile when my old sim card did work so I'm wondering what else he's lying about. Is there anyway to fix this?
