Yes — that is exactly what it is built for. Unlike voice-only call boosters, the D500 boosts Band 3 (1800 MHz), which EE uses for both 2G voice calls and 4G LTE data. The same weak outdoor signal that causes dropped calls also throttles your 4G; the 75 dB gain improves both at once, across 500 m², so calls stop cutting out and browsing, video and card-machine data get faster on every floor.

Yes. Virgin Mobile switched its UK service to EE's infrastructure from 2024, so Virgin SIMs now ride the same Band 3 (1800 MHz) voice and 4G frequencies as EE. The D500 amplifies that radio wave directly — just pop your existing Virgin SIM in your phone as normal. No new EE contract is required. BT Mobile, ASDA Mobile and legacy Orange / T-Mobile SIMs work the same way because they all use EE's network.

The D500 is the flagship D-series model. It covers 500 m² versus the D300's 300 m², delivers 75 dB gain versus 72 dB, has a better ≤3 dB noise figure versus ≤3.5 dB, a higher ≤27 dBm output versus ≤20 dBm, a 10 dBi Yagi outdoor antenna versus 9 dBi, and an 8 dBi panel directional indoor antenna versus the D300's 6 dBi. It also supports up to 50 users versus 30 and ships with 10 m outdoor plus 5 m indoor coax. If you have a 4–5 bedroom house, large apartment or small office, the D500 is the better fit; for a smaller 3–4 bedroom home, the D300 at its lower price point is adequate.

An 8 dBi panel directional antenna focuses the boosted signal harder in one direction — at your living room, home office or shop floor — rather than wasting signal in all directions. For a 500 m² space with a defined main use area, the higher-gain panel delivers a stronger, more concentrated signal where you actually need it, across more rooms. If your use area is spread evenly in all directions from a central point, a lower-gain omni might suit you better (that is the D250 approach).

Your 4G data will improve, but your 2G voice calls will not be boosted. The D500 amplifies Band 3 (1800 MHz), which Three uses for 4G LTE but not for 2G GSM voice (Three relies on 3G/4G calling and VoLTE). So Three, iD, SMARTY, Plusnet and Freedom Pop customers get faster 4G data, but do not get a traditional 2G voice-call boost. If voice reliability is your main problem and you are on Three, check whether VoLTE / Wi-Fi Calling is already enabled on your phone.

Yes. The D500 amplifies an existing weak donor signal — it cannot create signal from nothing. Before buying, check EE signal on your phone outside, near where the Yagi will sit on the roof or chimney. If you have at least 1–2 bars of Band 3 signal outdoors, the booster can push a full-strength signal inside across 500 m². If you show zero bars and emergency-only outside, no Ofcom-legal booster at this price will help.

If the panel indoor antenna leaks the boosted signal straight back into the outdoor Yagi, the amplifier feeds itself a loop and goes into self-oscillation — that causes noise, crackle and dropped calls, and can disrupt the mast. Keeping the two antennas at least 10 m apart vertically (e.g. Yagi on the chimney roof, panel antenna on the ground floor or first floor) breaks that loop. The 10 m outdoor coax, 5 m indoor coax and AGC are designed around this separation rule.

Yes. The D500 supports additional indoor panel antennas, each covering roughly 100–150 m². You would fit a splitter at the booster unit and run extra coax to each panel antenna on a wall or ceiling. Each extra antenna and the splitter are sold separately. This is a good route if your home starts at 500 m² but has a garage annex, a home office outbuilding, a converted barn or a second floor that needs its own focused signal.

The D500 is rated for up to 50 simultaneous users — phones, tablets, card machines and booking devices all connecting at once on voice calls or 4G data. In practice, a small office of 15–30 staff will never approach the limit, which is the point: the flagship 75 dB gain, ≤27 dBm output and 10 dBi Yagi are engineered so the unit does not saturate when many devices are active. For a 50-person office, expect stable calls and data for every device; beyond that, plan a second unit.

You are covered by a 365-day money-back guarantee, plus lifetime UK technical support. If the D500 does not improve your EE calls or 4G after a proper install (correct Yagi aim, 1–2 bars outdoors, ≥10 m antenna separation), contact support and you can return it by mail for a free return and refund. Free UK delivery takes 10–15 working days after 1–2 days order handling, so order early if you have an urgent deadline.
