This Product Discontinued or Obsolete
While current owners of this device or plan may continue to find performance to be adequate for the foreseeable tech-future, we do not recommend upgrading to or purchasing it.
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.

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).
