Just another old wives’ tale.
There was a time when a residential cell booster actually posed a real threat to cell towers. When cell boosters first came on the market, they actually had the ability to set up a feedback loop that could overload a nearby cell tower. However, those days have passed.
All the cell boosters sold by Solid Signal, including our Surecall and SmoothTalker, have feedback prevention electronics. These circuits will be required by law in the next generation of cell boosters but all the major manufacturers already use them.
The simple fact is, a cell booster is a harmless way for you to get better cell signal indoors and poses no more threat to the cell towers than your phone does.
