I called customer service. They confirmed that the internet is free for one year even on a month to month basis. The modem rental is free providing you pay for 10 dollar shipping. There was no dry loop fee in my invoice. I was only charged 11.30 for shipping. Let's see if this is too good to be true in the coming months.
The modem they are renting out is Smart RG SR516AC modem (AC1200)
