Yes — that is exactly what it is built for. If your EE phone drops calls or shows one bar on country lanes, A-roads or rural motorways, the CVD picks up the weak Band 3 (1800 MHz) outdoor signal with the roof antenna, amplifies it by up to 62 dB, and broadcasts it inside the cabin at a level your phone can hold. Most rural EE van drivers see calls go from dropping every few minutes to holding steady for the whole journey. It only needs 1–2 bars outside to work.

Just voice calls and SMS. The CVD is a 2G Band 3 (1800 MHz) voice booster — it improves call clarity and text message delivery only. It does not improve 4G LTE mobile data in your car. If you need in-car internet or 4G data, use a mobile Wi-Fi hotspot device or a separate 4G router with an external antenna. Do not buy this unit expecting faster streaming or Google Maps data — that is not what it does.

No. The CVD is Band 3 (1800 MHz), which is EE's 2G voice band. O2 and Vodafone use Band 8 (900 MHz) and Band 20 (800 MHz) for their voice and 4G services. If you are an O2 or Vodafone customer with dropped calls in your vehicle, you need the Boost4U CVG (Band 8 900 MHz voice booster) or CVC (Band 20 800 MHz 4G data booster) instead. Three is unsupported too — Three has no 2G network in the UK.

No. The magnetic antenna needs a ferrous metal (steel / iron) surface. A glass panoramic roof, aluminium body panel, carbon-fibre roof or fibreglass motorhome roof will not attract the magnet. On glass or non-metal roofs, you can place the magnetic antenna on the steel bonnet / boot lid instead, or use an adhesive pad mount. Position it as high and central as possible for the clearest signal to the nearest EE mast.

No — that is the whole point of the magnetic design. The antenna sits on top of the roof with a rubber magnetic base, and the 3 m coax cable runs down through the door rubber weather seal, which is designed to close around wires without damage. Installation takes 15–30 minutes with no tools, no drill and no bodywork modifications. Use the included cable ties to keep the lead tidy along the door frame.

They are completely different vehicle products. The CVD is Band 3 (1800 MHz) and boosts EE / BT / ASDA / Sky / Tesco 2G voice calls and SMS only — it is for people whose EE calls drop. The CVC is Band 20 (800 MHz) and boosts O2 / Vodafone / Three 4G LTE data — it is for people who need faster mobile internet in their van or caravan. Both cost £139.99, but they boost different networks and different services. Pick CVD if your problem is EE calls dropping; pick CVC if your problem is slow 4G data on another network.

Yes. All of these carriers run on EE's network, so they use the same Band 3 (1800 MHz) 2G voice signal. The CVD boosts the physical radio signal, not any specific SIM contract — so BT Mobile, ASDA Mobile, Sky Mobile, Tesco Mobile, TalkTalk, TalkMobile, T-Mobile and The People's Operator customers all get the same call-quality improvement. Just plug in your existing SIM and drive.

If you leave the booster plugged in and switched on while the engine is off for days, it will slowly drain the vehicle battery (~5 W draw). We recommend switching the unit off at the adapter when you park for more than a few hours, especially on cold winter nights when battery capacity is already lower. For daily commuting where the engine runs most of the time, this is not an issue — the car alternator keeps the battery topped up.

You need at least 1–2 bars of visible EE Band 3 signal at the point where the roof antenna sits. The booster amplifies that weak donor signal to a full-strength signal inside the cabin. If your phone shows zero bars and runs emergency-only outside, no Ofcom-legal booster in this price range can create signal from nothing. Before ordering, stand on your roof position outdoors and check your EE phone signal strength in field mode.

Yes — as long as your motorhome or caravan has a metal roof (for the magnetic antenna) and a 5V / 12V power socket. The CVD runs off the motorhome's 12V leisure battery or USB port while you are on site, and improves EE calls and SMS for everyone inside. Remember it is voice + SMS only — it will not improve your motorhome's 4G data or Wi-Fi. For touring caravans, mount the antenna on the car roof while towing, then move it to the caravan metal body on pitch.
