So I've been trying to change my phone number basically all day today. However, when I go to the self serve and follow the instructions it directs me to a page that says "Sorry, your session has expired. Please return to the main page and login again. Thank you". When I click on another city I am shown phone number options, but for some reason my city just shows me the error. Does anyone know how I can fix this?
Also, I've found that a few cities around me have the same area code I currently have, and wish to keep. If I were to just choose a different city and then select one of those phone numbers would that alter anything on my plan?
