Confirming free mobile line eligibility after 120-day port-out

Hello,

I'm porting my Xfinity Mobile number out temporarily and plan to port back after the 120-day waiting period to be eligible for mobile promotions attached to high speed internet. Before I do, I want to confirm in writing:

• After 120 days from port-out, am I eligible to port a number back to Xfinity Mobile as a free mobile line attached to the high speed Xfinity Internet plan I purchased this month?
• If yes, what would my total monthly cost be for one line after porting back? Would I incur any one time or monthly fees?

Please answer each question specifically. I'd like this documented on my account.

Thanks,
Jay
