From your cellphone can you dial 7 digits for a local number? I can dial 7 digits, 10, digits, 1+10 digits or +1 and 10 digits. If I'm out of my local area and the area has 7 digit dialing if I dial 7 digits I'll get someone in my local area code and not in the area that I am visiting! (if I'm on T-Mobile.) If I'm using another company's network I have to dial 10 digits.
