I can help you swap out the phones on your account.
Please reach out to me via private message. Click on my name ComcastJaredB and from the profile page click on the blue ‘send a message’ button. In your private reply please include the following information so that I may authenticate and access the account;
First and last name, mobile number, complete service address, and the last 4 digits of the pay method on file. Also, if you could please include the IMEI, device type, color and memory size of the phone you'd like to swap that would be greatly appreciated.
