A few words of caution when buying/selling digital terminals:
First, the serial number must be removed from one account before it can be added to another. As such, if you are the seller make sure you call Rogers or go to a store to have the serial number removed from the account BEFORE you give it to the buyer. This is a very common problem, when someone wants to activate their terminal but the CSR is unable to do it because it's bound to another account, and of course the CSR can't remove it from the account without the permission of the seller (account holder to the account the serial number is bound to).
Also, if you plan to cancel your whole account, and sell the purchased terminal to another customer, make sure you either do this AFTER the account is completely disconnected or have the serial number removed from the account before you give Rogers your 30-days notice. During the 30-days when your account is pending disconnection, the serial number will be locked to the old account, and transfer of ownership will not be possible.
When buying a terminal it's always a good idea to call Rogers with the serial number before the purchase to make sure it's free for use, and to make sure it's not a rental terminal. For security reasons a CSR will be unable to tell you what person is using the box if it's in use, but they will be able to tell you one way or the other if the serial number is currently bound to another account, and if it's owned by Rogers as a rental or not. This is extremely important because there have been people in the past selling rental terminals to other customers, either out of ignorance or stupidity (they wouldn't make any money since they'd just be charged for not returning the equipment to Rogers anyway). Either way, double-checking with Rogers before buying the box is a great idea, and always encouraged.
Finally, while it's true that there is no activation or deactivation fee for the digital terminal, the regular digital services fee still applies.
The CSR recommended the seller advise Rogers of who is buying the box (along with the serial number of the box being sold) in order to eliminate any problems for the buyer when activating the used terminal
I'm not sure what the CSR's rationale was for this suggestion. As long as the serial number is off the seller's account, and the buyer can read the serial number when they call in to have it activated, there should be no problems for the buyer. Even if the seller informs Rogers of who the buyer is, Rogers won't activate the terminal on the buyers account, or even associate the serial number with the account, without the buyers consent.
