I believe my husband is hiding a secret phone which he is using to cheat on me. I am 4months pregnant and would just like to knw for sure. He tends to be very violent when questioned but I found a tmobile card with the actuall sim card removed. I have the actual sim card number and would like to know if I would be able to get the phone number for it
More about :back phone number number listed sim card
if the sim card is not registered, you register it yourself and then you will be able to find out what numbers have been called and when, by contacting t mobile customer service.
I hope you're just being paranoid though and he is not cheating. good luck
