The SB918 Road-Tripper Car Signal Booster is a powerful and adaptable mobile signal solution designed to deliver reliable 2G voice calls and fast LTE 4G/5G data while you’re on the move. Built for drivers who demand consistent connectivity, this car signal booster addresses one of the most common frustrations of modern travel: weak or unreliable mobile signal in vehicles.
Whether you’re commuting daily, travelling long distances, exploring off-road routes, or managing a fleet of vehicles, the SB918 Road-Tripper ensures your communication stays clear, stable, and dependable.
Adaptable Signal Boosting for Vehicles & Fixed Applications
One of the standout advantages of the SB918 Road-Tripper Car Signal Booster is its adaptable design. While optimised for mobile vehicle use, the system can be easily converted for fixed or semi-fixed installations, depending on your needs. This flexibility allows it to be used across a wide range of environments without sacrificing performance.

Boosts More Than Just Mobile Phones
The SB918 Road-Tripper goes far beyond improving mobile phone reception. It is designed to boost signal for any SIM-enabled device operating on supported frequencies. This makes it a valuable connectivity tool for both personal and professional use.
Supported SIM-based devices include:
-
Credit card machines and POS terminals

Wi-Fi dongles and SIM-enabled routers
-
Tablets, iPads, and laptops
-
CCTV systems and SIM-operated cameras

IoT devices, Raspberry Pi units, and industrial controllers
By strengthening signal for multiple devices simultaneously, this car signal booster supports productivity, security, and communication wherever your journey takes you.
Solving the Problem of Weak Vehicle Signal
Unreliable 2G voice calls, SMS delivery issues, and slow LTE 4G / 5G data are common challenges inside vehicles. These problems are often caused by natural signal loss, long distances from base stations, terrain variations, buildings, vegetation, and shadow effects that interfere with wireless communication.
The SB918 Road-Tripper Car Signal Booster is engineered to overcome these challenges by capturing weak outdoor signals, amplifying them, and redistributing them inside the vehicle. The result is clearer calls, fewer dropped connections, faster data speeds, and a smoother mobile experience, even in difficult signal conditions.
Dual Band Technology for Broad Network Support
Powered by dual-band GSM/DCS and LTE 900/1800 MHz technology, the SB918 Road-Tripper is capable of boosting 2G voice calls, LTE 4G & 5G data across multiple networks. It supports major South African operators including Vodacom, MTN, Telkom, Cell C, and Rain, as well as many mobile networks across Africa.
In certain regions, LTE 4G performance on the Telkom network may vary depending on whether local towers transmit on the 1800 MHz band. For best results, we recommend confirming your local frequency allocation with your network provider.
Simple Installation & Easy Operation
Installing the SB918 Road-Tripper Car Signal Booster is straightforward and user-friendly. The system is designed for quick installation with minimal technical knowledge, following a few clear steps outlined in the setup guide. ICASA approved.
Once installed, you’ll immediately notice improved call quality and more stable data performance. No more repeating yourself on calls or struggling with slow internet while travelling — the SB918 Road-Tripper delivers consistent connectivity you can rely on.

I’m a mobile doc operating in Limpopo. I needed something reliable for remote clinics. This booster hasn’t failed me yet. Solid piece of kit.
Tinashe Mutale – Lusaka, Zambia –
I’m in logistics in Lusaka—5 of our trucks now have SmartBoosters. Drivers say comms are sharp now even in dodgy zones. We just placed an order for 7 more.”
Josh Mohapi – Maseru, Lesotho –
You haven’t lived until you’ve driven the Lesotho highlands in winter. No signal, no help… until I bought this booster. Now, my wife can track my every move. Bit too well, maybe.
pieter.dewet – Bothaville, Free State –
On the farm here near Bothaville, I thought signal boosters were a gimmick. Then I saw my neighbour’s setup. Got one the same week. Now I can even do Zoom meetings from the bakkie.”
Denise Vermaak – Western Cape –
My bestie from Mossel Bay told me, ‘Girl, just buy it—you’ll see!’ So I did. Honestly? I’m chuffed. I even got signal halfway between George and Oudtshoorn. This thing is next level. Pricey, yes, but not moer of a gamble with that 30-day guarantee.
Sibusiso Mkhari – Thohoyandou, Limpopo –
Bought this thing for my work trips to Venda. Usually, the signal just vanishes, hey. Now it’s rock solid. Spoke to a real gent on WhatsApp—he sorted me out properly. Aweh.
Ghanzi, Botswana –
Look, I don’t usually spend this kind of money unless I’m sure. But I’m glad I trusted my mate in Gaborone. This booster survived our desert trip to Ghanzi—worked like a bomb.”
Port St. Johns, Eastern Cape –
So we drove from Jozi down to Port St. Johns—no signal dropout, not even past Bizana. This thing just works. Pricey, sure, but eish, now I can’t drive without it.”
Aslam khan – Durban, KZN –
My cousin said ‘boet, this thing gives you signal in places Eskom can’t even reach!’ He wasn’t lying. I cruise all over KZN and I’m always online now. Lekker product, excellent service.
Oma Steyn – Upington, Northern Cape –
My vrou and I do long drives from Upington to Kakamas. She wanted signal to call the kleinkinders. Now she’s happy—no more signal complaints. Worth every cent.
