Cell Signal Booster

My sensors (two Modulair-PMs) are currently located in an area with weak cell coverage. I am considering purchasing a cell signal booster that would amplify the signal from the nearest AT&T tower to increase the cellular strength and connectivity of the sensors. Has anyone tried this before? Does this seem like it will work as a solution to the cell connectivity problem, or should I anticipate issues with connecting the sensors to a boosted signal?

Hi @oliviawuttke - what are the serial numbers?
