BlackBerryModem on CDMA Networks
I googled the Net and found the necessary information for Bell Mobility and Sprint users. This is an extrapolation (prediction) of what is necessary to make the 7250 work as a modem. No guarantees. Replace 8005551212 with the 10-digit phone number of your BlackBerry.

Also, there is an alternate phone number "#19788" if you are unable to dial using #777.
