Internet residencial

I am a fulltime traveler and purchased the home internet at my primary residence and specifically asked the attendent at the store if I was able to use the home internet with me since my home is in an RV fulltime for my sabbatical. He said yes. 

I learned that the carrier is changing this availability and raising rates over 300% starting May 8. If so, I will return the device and will shop for a new cellular carrier, as well. There are far more competitive options nowadays. Besides, the home internet is very poor reception most times. I never complained about it, but to charge more for the same crap is simply not worth it. It was mostly throwing money away as a backup.
