Even though there is an option on the web page to upgrade this phone, evidently you cannot. I purchased this phone as an upgrade. When I received the phone, I also received a new phone number and bill on my AT&T account. When we asked AT&T about this, we were told that we would have to speak to the seller. When we spoke to A-1, who sold this phone on Amazon, we were told that they were unable to do upgrades. They did go through the trouble of checking the website, and to their amazement, they were able to access the upgrade options as well. Even after this, they refused to treat my purchase as an upgrade so that I could keep my old phone number, or cancel the new phone number. We spent two hours working on this situation. Over and over we were told that our only options were to keep the phone and the extra phone line that came with it or send the phone back. We couldn't justify an extra phone line that we would not use, so now, the phone is back at A-1. My Amazon days are over. Why advertise, and allow somone to order something, in this case an upgrade, that they will not receive? Good-bye Amazon...
