Use ADT system with no monitoring company?

[Tony Sivori <TonySivori@xxxxxxxxx>]

I'm buying a house that has an ADT system installed. Pretty basic system,
just the front, back, and basement door, plus one motion detector.

The house is a repo, so I won't be getting any codes from the previous
owner.

I've Googled, and seen that an ADT system can often be reused with another
monitoring company. Presumably one with better service and perhaps even
better price.

But I'd like to go an even cheaper route, and have the alarm call my cell
phone. Is this possible, and if so how much might an alarm company charge
to set up the system to call my own cell phone?
