To add to this... I ditched my modem rental years ago and bought my own modem for $58. Be prepared to give them the MAC Address for this modem that you buy. The MAC Address is how they identify this modem to being licensed for use with your account. Once they add this MAC address to their system, you will need to turn the modem on in which you may need to loginto it to configure it. For myself I didnt require any configuration as for once my motorola was connected to the ISP when booting they had me on the phone and they had access to flashing it. The modem then did a reset and when it came back up it was ready to go. Hope this info helps. The MAC address is usually on a sticker on the modem. And something like 01:e4:fe:98:4a:c0 or 01e4fe984ac0 in which your 12 hex digit mac address will be different than this mac address example, but should be on it for easy identification, although usually in very small print. *Additionally to get my modem set up I had to talk to 3 people, 2 of them said it wasnt an option and that i had to continue top pay on the rental modem. The 3rd person I chatted with processed my request and I just had to return the rented modem to my ISP. My ISP is Comcast and not AT&T. They could play stubborn, but hopefully your able to find someone that allows it.
