I have been trying to use my phone for almost a week to call my work. Every time I dial the number it says that call can not be completed. The phone does work with other numbers. However this is a working number. When I use my mom cell I can make the call. This is very frustrating because this is a working number. I have tried it a different times through the day and am still getting no where. I really like my phone but not sure what to do if I cant call a number that should be working.
