Dunno, really think that it should be the carrier who rent out these boosters, even free of charge to retain/attract more customers, if customers complain lack of signal in their covered zone.
They already lost me and some of my friends/family members just because we did not have usable signal at home.

This is what carriers have done in many other countries.
Customer complain lack of signal at home, they visit, they confirm it should be covered, and they put a booster for free of charge.
