If you’re struggling with dropped calls, slow mobile Internet, or “No Service” on your Three Ireland phone — we understand your pain. Despite Three’s claim of 99% 4G population coverage, real-world signal remains weak in rural areas, stone-built homes, basements, and modern offices across Dublin, Cork, Galway, and especially in counties like Donegal and Kerry.
What’s the solution? A CE-certified Three signal booster designed specifically for Three’s 4G and 5G frequencies in Ireland. At MyAmplifiers, we’ve been helping thousands of Irish customers since 2001 — and our Nikrans boosters are engineered to work flawlessly with Three’s network.

Did you find what you were looking for?
If not, please describe the issues encountered while searching for a booster model or choose from the variants below.

Three Ireland carries over 68% of all mobile data traffic in the country — more than Vodafone, Eir, and Tesco Mobile combined. Yet, high demand doesn’t always mean a strong signal where you are. Here’s why:
Did you know? In late 2024, Three shut down its 3G network, and the freed-up frequency bands were reallocated to 4G and 5G services. As a result, strong and reliable 4G/5G coverage has become essential for uninterrupted connectivity.
Not all signal boosters work with Three. To amplify your signal reliably, your device must cover active Three bands:
| Technology | Frequencies Used by Three Ireland |
|---|---|
| 4G/LTE | 700 MHz, 800 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2600 MHz |
| 5G NR | 700 MHz , 1800 MHz, 2100 MHz, 3500 MHz |
Many inexpensive signal boosters sold online only support a limited range of frequency bands. While they may provide basic 4G coverage in some areas, they often don’t support the critical frequencies used by the Three Ireland network, particularly those used for providing connectivity in rural areas and for 5G networks in cities.
Before purchasing from MyAmplifiers, we’ll help you check that the booster fully supports the active LTE and 5G NR bands of the Three network listed above. All solutions distributed by MyAmplifiers are pre-tested for Three Ireland and support every frequency listed above. They’re also CE and RoHS certified.
We tailor solutions based on where you need coverage and what type of signal requires improvement — voice calls, 4G, or 5G:
This type of solution does wonders to stone cottages in Kerry, farmhouses in Westmeath, or suburban homes with poor indoor reception. Our boosters capture weak outdoor signals and rebroadcast strong 4G/5G indoors. A solution like this is best for families, remote workers, and smart home users. The model in this category that’s worth your attention is the Nikrans NS-600-Smart.
Amplifiers for offices and small businesses provide coverage in multiple office rooms and can support more than 50+ simultaneous users, which is ideal for video calls, cloud applications, and POS systems. The Nikrans NS-2000-Smart+5G is a popular option that you can try.
Vehicle boosters are compact systems with magnetic mount antennas. They provide high-quality communication and a stable 4G/5G signal on rural roads and coastal routes.
Since they work while you’re moving, they’re ideal for delivery drivers, tradespeople, and sailors. We recommend the Nikrans NS-GD-Drive model for cars and the Nikrans NS-GSM+4G-PRO-Boat model for boats.

Still unsure? Describe your location and what type of signal you’d love to refine, and we’ll recommend the perfect model.
Yes — but only if it supports Three's frequency range. All boosters distributed by MyAmplifiers are compatible with this provider.
Absolutely. Every Nikrans booster we supply has CE and RoHS certifications and fully complies with Irish and European standards.
Most of our models are multi-operator — they'll boost Three, Vodafone, Eir, and Tesco Mobile simultaneously. Check product specs for details.
Yes — if poor signal is the bottleneck. A booster turns "1 bar of 4G" into "full bars", often doubling or tripling download speeds for streaming, WFH, and smart devices.
A signal booster can't create a signal — it only amplifies an existing outdoor signal. If you have zero bars even outside, it won't work. But if you see 1–2 bars near a window or outdoors, our models will significantly improve Three's 4G/5G coverage indoors.
