We had an old device that worked for 3G
We had an old device that worked for 3G and 4G but it stopped completely, and it was awful trying to work with almost no signal. On a good day we might get 1 or 2 bars in one tiny spot in the office. While we were looking for options we came across Signal Hero. They had a solution that supports multiple networks and some 5G signals, so we decided to give it a try. The whole process with Signal Hero was smooth. They guided me through everything, checked our signal properly, and even made a custom installation plan for our place. I was a bit concerned about compliance, but they provided the relevant documentation and we were comfortable proceeding. We ordered the all networks 4 band kit. Now the office has a solid 4 to 5 bars throughout most areas. It is brilliant. Very happy with both the service and the product.

I’d been struggling with phone calls…
I’d been struggling with phone calls for about six months. No idea what changed, but the signal at my place suddenly went from “not great” to absolutely terrible. After a bit of Googling I ended up on the Signal Hero website. The team asked me to check my outdoor signal and see which mast I was picking up from. What really surprised me is I’d never had 5G here before, but once the booster was switched on I started getting 5G straight away. Honestly felt like magic, I didn’t even realise these boosters were a thing. We’ve just finished the installation in our caravan as well. Inside we used to have 1 bar, maybe 2 if I stood in the right corner. Now it’s solid. Many thanks to the team, genuinely recommended!

I was really struggling to get any…
I was really struggling to get any signal in the basement service from all mobile providers here is just rubbish. At first, the booster kit didn’t seem to fix it, so I got in touch with the Signal Hero support team. They checked everything and found out my phone was picking up a specific 5G signal that worked great outdoors but not with the booster. It actually worked fine on other phones! They swapped my unit for a different one, and now I’ve got full bars everywhere. Big thanks to David and Diana for the professional and friendly help.

Highly recommended
I bought a mobile booster from Signal Hero for my garden office. It was good value and most importantly, it was easy to install and works well. Both before and after I placed the order, I received outstanding technical help from their signal expert George, in particular with advice on signal strength and best placement for the external aerial. I now have 4 bar mobile stength in my office and highly recommend Signal Hero. I would certainly use them again.

Bought this booster for my bunglow
Bought this booster for my bunglow and I've got to say it's doung a cracking job. Used to barely scape 1 bar in the living room, now I'm sitting on 4 solid bars, quite the difference! Massive thanks to George for walking me through all the tests, helping me pinpoint the perfect spot for the outside aerial and even coming up with a way to run the cables without any drilling. Top bloke, much appreciated!

brought the car booster for our company
brought the car booster for our company vans. Wasn't sure at first, but after a few weeks on the road, we're impressed. Drivers can stay in touch reliably now, no more dropped comms. Might kit out the fleet soon.

Mobile signal boosters work in offices by capturing the available outdoor mobile signal through an external aerial, amplifying it with the booster unit, and redistributing the improved signal throughout the office via an indoor antenna.
This helps provide stronger and more reliable mobile coverage for calls, texts, and mobile data, particularly in areas where signal is weakened by thick walls, building materials, distance from the mobile mast, or other obstructions.
Installing our mobile signal boosters is a quick and straightforward process. For standard kits, most customers do not need professional help — in fact, 98% of our customers install the boosters themselves.
Our systems are designed to be plug-and-play. Installation mainly involves connecting the components with the supplied cables and mounting the outdoor and indoor antennas in the correct positions.
We provide clear installation guides, step-by-step videos, and technical after-sales support through our contact channels to help you with setup and optimisation.
If you purchase a customised solution or a system with multiple antennas, additional cables, splitters, or more complex coverage requirements, professional installation can also be arranged through our installation partners in Ireland upon request.
We offer a 2-year warranty on every product, including accessories, with the option to extend your warranty to 3 years for additional peace of mind.
Our technical support team is available 24/7 to assist with any questions about your purchase, installation, or setup.
If you would prefer professional installation, our trusted installation partners in Ireland can also assist with installing and configuring your mobile signal booster upon request.
Certain boosters can cover areas of up to 1,000 m². For larger properties or more complex coverage requirements, we offer customised solutions tailored to your building and signal conditions.
Our team can provide online consultation, system planning, and installation layouts to help ensure the right setup for your property.
For more information or to discuss your requirements, contact us by phone or email and our technical team will be happy to assist.
We offer a wide range of mobile signal boosters, with our more powerful models particularly well suited to offices and commercial spaces with multiple simultaneous users.
For larger offices or locations where several mobile frequency bands need to be supported, we recommend considering our tri-band and five-band solutions.
If you’re unsure which model is right for your office, contact our Customer Care team through the Contact Us section. We’ll be happy to recommend the most suitable solution based on your building size, mobile networks, and coverage requirements.
