Activating Xinfity Internet Through the App
I am a new customer and I am trying to set up my internet at a new apartment. When I get to the part where I need to activate my modem on the app, I run into issues. I sign into the app and get a screen that says “sorry that didn’t go as planned.” I have tried signing out and back in and reinstalling the app, but it still doesn’t work.

Try calling 1-855-652-3446. That is their self-install device activation line.
If that doesn't work for you, you can call 1-800-comcast and tell a rep that you would like to have a new modem provisioned for service. Have the RF / CM / HFC MAC address and the serial number of it handy when you call.

Hey there, user_z63d8p! Thank you so much for taking the time to reach out to us here on the Xfinity Forums. I am sorry to hear about the troubles with activating your modem. Did you get everything resolved and the modem fully activated? Are you still needing assistance with further activating the account?
