Potential Current Option: Surecall2Go 3.0
The SureCall TriFlex2Go booster came in three carrier specific versions - with a model specific to Verizon, AT&T, and T-Mobile.
All three boosters support the widely used 800Mhz and 1900Mz 2G/3G bands, but each only supports the LTE bands of the specific carrier it was sold for.
The AT&T version supports LTE Band 17, the Verizon version supports LTE Band 13, and the T-Mobile version supports LTE Band 4.
We tested two of the TriFlex2Go boosters (the AT&T and Verizon versions) in 2014 (provided courtesy of Powerful Signal), and they performed well - but given the carrier specific limitations, higher cost (original list price was $600!), and how physically bulky these units are - we couldn't find any reason to recommend this product line over other better options.

SureCall TriFlex2Go Ratings
Unlike more recent 5-band boosters, the TriFlex2Go came in versions specific to each carrier - limiting flexibility. It was more expensive, and performed worse than alternatives from other booster manufacturers.
