The line of Cel-Fi "Smart Signal Boosters" from Cell-Fi by Nextivity are unique designs that work in a fundamentally different fashion than most other cellular boosters on the market.
They are digital boosters, not analog like most others on the market, which allows them to have a higher gain while mobile. The booster is controlled by a mobile app, and can only boost one carrier network at a time.
Cel-Fi has been a major player in the residential and in-building booster market for years, and in 2017 introduced its first booster designed for mobile use - the Cel-Fi GO.
Product Variations
The mobile line-up of the Cel-Fi GO/GO+ comes in three different kits. The amplifier remains the same for each kit, with the included antennas and mounting hardware making each kit unique.

News, Videos, & Status
We began communication with Nextivity about the development of this product starting in the summer of 2016 and received a pre-production unit for evaluation in May 2017. We have included this unit in multiple rounds of testing.
In November 2019, we completed our initial and extensive rounds of testing of the updated GO, and our results are summarized in the member area below.
We may revisit this booster again in the future should there be substantial firmware updates that can further improve performance and usability.
Members can also follow our testing activity in our forum, where we'll post updates and our latest insights and information.
Members can also dive deeper and access our raw and ongoing results as we conduct our testing in our Testing Lab:
- Cellular Booster Intensive – weBoost Drive Reach, SolidRF RV Pro, Cel-Fi Go-M (Summer/Fall 2019)
- Booster Bonanza – weBoost Drive Reach, SolidRF RV Pro, Cel-Fi Go-M, Poynting 402 vs 4G-X (Summer 2019)

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).
