I want to return the modem so that I don't get charged for the monthly modem fee. Does the account holder have to come in person? Can any of the family members return it?

Got it, thank you all.

I do not have the necessary information. Call customer service.

No. I've returned someone else's equipment with no problems

I returned modems for family members

WHAT DIFFERENCE IT MAKES AS LONG AS THEY GET BACK THEIR MODEM?

Doesn't matter who returns it, they scan the serial number on it.
