It seems that right after you get a new cell phone, a
newer one with improved features comes out. Standard mobile
service contracts allow you to upgrade after two years.
Several major carriers are offering a new type of contract
that allows you to upgrade sooner.
While standard phone contracts require you to pay only a portion of the phone’s full cost (up to $250), these new plans may require to pay the full cost of the phone ($600 or more). Before you sign up for these early upgrade plans, do your homework.
Some question to ask include:
Keep in mind that if you have an early upgrade plan and pay the entire phone’s price, you may still be required to return the phone to your provider on your next upgrade. Also, if you owe money on the phone, you may not be able to switch carriers until the balance is paid.
