How it works
A booster receives a usable mobile signal outside, strengthens it, and rebroadcasts it inside. We show what is in each kit, where it belongs, and what it cannot fix.

Start with the problem
Good advice starts with three details.
Square metres, the network you use, and whether you can find usable signal outdoors. That is usually enough to narrow the field.
- Measure the space: Match indoor coverage to your actual floor area, not a hopeful guess.
- Check your bands: A booster only helps when it supports the bands your network uses.
- Look outside: The system needs an outdoor signal to bring indoors.

Frequently asked questions
Will a booster work if I only have 1 bar?
A booster needs some usable signal outside, usually at least one steady bar where the outdoor antenna goes. It amplifies existing signal and cannot create signal where there is none. Test outside or on the roof first.
Does it work with all networks?
Our multi-band kits cover the main frequencies used by EE, O2, Vodafone, Three, so they can usually boost them at the same time. Check the bands listed on each product.
Should I choose 4G or 5G?
Most kits boost 2G, 3G and 4G voice and data. Most 5G phones use 4G for calls, which can be boosted; 5G support is listed only when the product data says so.
How large an area can it cover?
Coverage depends on the kit and the strength of the outdoor signal. Check each product’s stated coverage; weaker outdoor signal usually means less indoor coverage.
How difficult is installation?
Many installations take about one or two hours: place the outdoor antenna where signal is best, run the cable inside, fit the indoor antenna and power up. Keep the antennas apart; our live chat can help.
Is it legal to use?
We can sell it, but getting permission to use it is your responsibility, so check with your mobile network or national regulator before installing.
What about returns and warranty?
Returns are available within 30 days. A 1-year manufacturing warranty is included.
