a house alarm is a closed loop system, no external communication till you hook up a service, if they've never had a cel service, that box in their closet has no outside cell connection.

now it may have something for a land line like a dialer, but again her cell can't communicate to it.

Why yes, yes she did.

sounding more like kate, huh? see how well that worked out.

maybe she's somehow programmed it to call her cell phone when they change the code... if it can call a monitoring company it can call a cell phone...

take her phone away. done deal.

she should have bitch slapped him more often then he would have been scared to leave.

our cell phone co, came out and installed a cel device. alarm boxes don't come w/ them.

no, but even a normal landline system can call whatever number the service company programs into it. if she figured out how to program her cell number as that number then maybe she gets messages when the codes are changed.

That usually requires the system to be activated with the alarm company to send out those messages.
