This thread points out something that many don't seem to understand.
When you are buying a service, any type service, and you ask that the
service be changed, that's a change in the contract. In many cases,
besides cell phone service, & in all cases when it's cell phone
service, you need to read the papers you are signing for the changes
and know everything you have signed. If doing the change on line, your
best bet is to record the conversation & ask specificately if it
changes your contract dates.

I have a cell phone contract that was signed for 1 year. That was 7
years ago. When I view my account on line, it says my contract
expiration date is Janurary 14, 2002. I haven't change anything &
will not, because I can't get the same rates on current plans from
anyone.
