When I originally signed up with Frontier about five or so years back, using your own modem was an option (actually in their promotional material) and I just assumed that was still going to be the case.
So did you use your own modem at that time? I signed up seven years ago and was given a free modem (without the fee).
To get the fee removed, I think you have to be an older customer who was issued a free modem way back when they weren't charging a rental fee to begin with.
Also, it doesn't hurt if a Customer Service rep makes unauthorized changes to your account without your permission resulting in being charged the fee, which -- in my case, I had never paid in seven years as a customer.
However, if you left Frontier after those five years and came back, you will have to pay the fee no matter what -- even if you buy the same modem yourself.
