Activate modem/router without app

I'm moving to a new apartment and I need to activate the modem/router I received from Xfinity in order to connect to the internet. Is there a way to do this without using the app? I have a very old phone and it's not capable of even downloading the app. It's frustrating that there isn't any sort of alternative means of activation provided. Thank you for your help!

Connect it to the coax line / outlet and power it up. Let it fully sync up with the system. Check that the front or the top panel indicator light(s) is / are steadily lit. Then call 1-855-652-3446. That is their self-install device activation line. Have the RF / CM / HFC MAC address and the serial number of it handy when you call.
