xFi unlimited data and money
I was told that if I sign up for xFi it will cost me $15 a month and give me unlimited data.
When I called Comcast the customer service lady tells me I need to spend $15 for modem. $10 for phone line. $10 for unlimited data.
So instead of $15 I will have to spend $35.
Is it true that to get unlimited data I need to spend $35 ?
