Review: Smoothtalker (Mobile Cellular Booster)

The Mobile RV X6 Pro is Smoothtalker's new flagship mobile cellular booster.

Smoothtalker has been around forever making cellular boosters (they claim to have released the first digital cellular booster in North America in 2001) - but they've been slow to transition to LTE and multi-band support.

With only 2G/3G support and no LTE-friendly options, Smoothtalker had managed to fall completely off our radar.

But in early 2017 Smoothtalker at last launched a full lineup of completely new "6 Band" LTE boosters - ranging from cradle boosters to RV / large vehicle boosters, to full-home residential and even large commercial systems.

Particularly interesting to RVers is Smoothtalker's new Mobile RV X6 model, which we have been testing since the beginning of January.


  • Gain: 50dB
  • # of Devices Boosted: Many
  • LTE Bands Supported: 12 (17), 13, 5, 4, 2, 25
  • Exterior Antenna:  Magnetic mount with integrated cable, other antenna options available. FME end.
  • Internal Antenna: Patch antenna with integrated cable, FME end.
  • Range of Interior Coverage: Depends on external signal.
  • In Motion Usage: Yes
  • Power Supply: 12v (Optional 120V supply available)
  • Retail Price: $499

Alternative Versions

Smoothtalker has a range of models available. Here is Smoothtalker's new lineup of mobile-suitable boosters:

  • 15dB Inline Direct Connect Booster - $299.99 - This seems comparable to the weBoost Signal 4G, and can directly wire inline between a cellular router or modem with an antenna port, boosting the signal from an external antenna. In our experience, this style of booster is only interesting in a very limited range of use cases.
  • 23dB Cradle Booster - $329.99 - This seems comparable to the weBoost Drive 4G-S cradle booster, though Smoothtalker claims that their booster has a lot more output power to enable better upload and fringe area performance. It does however cost substantially more. Cradle boosters can be great if you only need to get a single device online with a boosted signal.
  • 50dB Mobile RV X6 - $499 - This seems to be on paper comparable to the weBoost Drive 4G-X, our current top pick cellular booster. This is the Smoothtalker booster with the most potential for RVers, and the one we have received for testing.

Smoothtalker has four antenna options, and apparently will support both magnetic and thru-hole mounting.

All the Smoothtalker boosters support a full 1W radiated output power, which they claim is more powerful than most competitive boosters - and should thus be most comparable to the weBoost Drive 4G-X as opposed to the weaker weBoost Drive 4G-M.

Smoothtalker also tells us that their boosters are "more sensitive to weak signals" and that they waited so long to come to market because they "didn't want to launch with something that they were not 100% confident in".

The flagship and most appropriate for RVers is the Mobile RV X6, and that is what we've focused on here.

Review & Testing Status

Smoothtalker sent us an evaluation unit of the Mobile RV X6 kit, which we have tested head-to-head in two field testing rounds.
