Cellular boosters can be quite useful for boosting the signal to a smartphone to get a more solid phone call. But when it comes to enhancing cellular data performance, things get more complicated.
Because of a technology called MIMO (multiple in multiple out) that is essential to LTE and 5G data, often times the internal antennas on a smartphone or hotspot don't benefit from an amplified signal. Boosters also only cover a handful of the frequency bands the carries use for data.
But a booster can play a role in a mobile internet arsenal - as they excel during times when you are really far from a tower, or where upload speeds are important (such as video broadcasting).
