We make the best effort to verify the MAC ID is purged from that Provider’s database as a part of the refurbish process, BUT on occasion they aren’t. If you get one that can NOT be activated as a result of the MAC ID, then please email Arris/Motorola and they’re going to promptly exchange your modem.
This Certified Refurbished product is manufacturer refurbished, shows limited or no wear, and includes all original accessories plus a 90-day warranty. IMPORTANT NOTEL: A couple of units might show the brand as Motorola (and not Arris) as Arris had acquired Motorola for 2 years; hence it’ll be the same product and the same model
