The Motorola C139 is one of those phones you would give as a gift to someone you really don't like and wish to torture for the life of the contract. The menus structure is very confusing which is unlike most other Motorola phones on the market today.
The size of the phone and keypad lends itself to be used by only children or adults with really small fingers. If you do not want to be annoyed every time you make a phone call do not purchase the Motorola C139.
