I know it's not the right group but Alarm pepole are resorcefull. and I a member of the group so I thought Id ask.
I used to have two numbers to the two different cell companies.
It goes to the local cell tower and gives you a dial tone then you dial the cell number, of the long distance cell phone without long distance charges.
My daughters phone is from a Mayer land account.
If I dial 579-7626 and then 240-575-0060 it rings
Any clue as to the numbers
