Hi graham. While viewing the contact, press Menu then choose Edit from the options. You should see a 'x' or "-" on the right side of the phone number. Tap on it to delete the phone number. Tap on Save when done.
No answer. Have a additional question regarding deleting a second telephone number. Problem, when I touch # it automatically calls someone else. I don't know when texting what # the msg is being sent to. How do I find out on msg sent. Please help. Thx
