I need a new modem can I pick up my new one and then return the old one the next day?or send it

Should be able to that. Because I picked up new and returned old one later.

Yes, I did it. Call to verify.

Call them, its theres isn't it.

Call Xfinity for their procedure. But I have seen folks bring in their old modem and be given their new one on the spot.

No. In order to get a new one you'll have to turn in the old one

Take it in

I need to pick up my new modom
