In many situations faced regularly by off-road enthusiasts around the world, a cellular phone or smartphone may be your only source of contact to the outside world. Cellular coverage is generally good from coast to coast — but if you’re traveling off the beaten path or visiting a largely uninhabited location, you may not be able to obtain a signal on certain, or any, cellular networks.

Further, in certain types of off-roading, you’re more likely to be faced with a loss of cellular signal. Rock crawling, for instance, often involves travel to remote locations and tackling the sort of rocky, treacherous terrain that seems to do a better job of sucking up cellular signals, rather than allowing them to pass through. Sand dunes can have a similar effect, and especially in a low-lying area where you’re surrounded by signal-blocking landscape on all sides.

In the case of an emergency, malfunction or another setback in an isolated location, your handset is likely your only gateway to the outside world, which makes it important to take steps in ensuring you’ll have a strong and consistent signal at all times.

Below, we’ll look at various cellular signal booster options that are designed to do just that.

Just a note before we proceed: given the numerous factors that affect cellular connectivity, be sure to take owner reviews of any product you’re considering with a grain of salt. A cellular signal booster is not a replacement for proper emergency preparedness and safety. You’ll also want to ensure the signal booster you’re considering is compatible with the cellular network your device is using. Contact your service provider for more details.

Finally, we found a lot of very low-priced cellular signal boosters that typically amount to a peel-and-stick foil sticker you attach to your handset. We doubt the effectiveness of cell phone signal boosters like these, and the owner reviews for the cheapest boosters we could find were disappointing at best, so you won’t find those below.

surecall n-range vehicle cell phone signal booster

If you’re after a cell phone signal booster that’s designed for a tidy and discreet install, look no further than the SureCall N-Range Vehicle Cell Phone Signal Booster Kit. Unlike numerous options on our list, this product features a modern-looking, low-profile external antenna that’s small and thin and difficult to spot. This antenna connects to a central module that’s powered by your vehicle’s 12-volt power outlet, and the incoming signal is analyzed, amplified, and transmitted via a secondary antenna to your handset.

The SureCall N-Range Vehicle Cell Phone Signal Booster Kit is backed by solid owner reviews — with most reporting positive if not miraculous results. A hands-free cradle is included to keep your handset easily within reach. This unit requires running some additional wiring, though it can be moved with relative ease between vehicles.

WeBoost Drive Sleek Signal Booster

Whether as a gift to give that off-road enthusiast some additional peace of mind, or as some added confidence that can be easily moved between your Jeep, truck, boat, ATV or Kayak, the WeBoost Drive Sleek Signal Booster looks to be a solid buy. Included are a Smartphone cradle that clips to a climate control vent, as well as the signal booster module itself. Using an exterior-mounted antenna, the WeBoost Drive Sleek Signal Booster makes a connection with the nearest cell tower, and amplifies that signal up to 32 times.

The amplified signal is then transmitted to the user’s phone through a second antenna that’s embedded within the cradle. The WeBoost Drive Sleek Signal Booster is compatible with voice and text messages, and can be used on all major North American cellular networks.

Just do your homework, first: owner reviews are mixed, and the externally mounted antenna will need to be moved between vehicles to stay with the user. The device also needs to be powered. A 2-year warranty and 30-day money-back guarantee add the confidence you may need to try this one out.

Proutone Cell Phone Signal Booster

We like the looks of this cell phone signal booster because of its fantastic owner reviews, reasonable price-point, and the fact that it’s designed specifically for use in a vehicle. With support for numerous cellular networks and the ability to boost both voice and data signals, the Proutone Cell Phone Signal Booster can help make connections in tricky locations, and help ensure you receive that important incoming call, no matter where you are.

Cellet New Car Cell Phone Signal Strength Booster

cellet cell phone signal booster

The owner reviews are OK at best and we’re not sure of the science behind the Cellet New Car Cell Phone Signal Strength Booster, but given its low asking price and handful of positive owner reviews, we’ve added it to our list.

This non-powered and totally passive antenna installs in seconds—you just fix it to your vehicle’s rear window and fix the inner antenna to the other side, on the inside of the glass. That’s all there is to it. The antenna picks up some of your phone’s signal and ‘retransmits the energy with a bigger antenna’ as stated in the Q&A section.

The Cellet New Car Cell Phone Signal Strength Booster is cheap enough that some buyers may be tempted to give it a shot—and a few of the owner reviews do look a little promising. Still, given the wide number of factors affecting cellular signal coverage, we’re not sure how easy it would be to trace any signal improvement specifically to this device.

In any case, the Cellet New Car Cell Phone Signal Strength Booster means you no harm, and might help you pick up a signal in a low-reception area—so if you’re a skeptic not willing to drop $150 or more on a quality powered cell signal booster, it may be worth a shot.
