Digging this one up from the archives...

Still have an old integrated Startac, and don't want to pay for an upgrade? I just wrote up the following - got mine activated and working again in my 2000 W210, didn't cost a thing. Works as good as the day it was delivered.

If you've a dual mode Startac that is CDMA (originally provisioned on Verizon), the process should work. TDMA - sorry, you still need the expensive upgrade.
