Yes. The W300 boosts Band 1 (2100 MHz), which EE uses for both 3G calls and data. All EE phones support Band 1. To confirm, dial \*3001#12345#\* on iPhone → Serving Cell Info → check Freq Band Indicator, or use LTE Discovery on Android. ### Does the W300 improve 3G data speed? Yes. The W300 amplifies 3G UMTS signals on Band 1 (2100 MHz), which can improve data speeds from 1–5 Mbps (no signal) to 10–30 Mbps (good signal), depending on your nearest mast's capacity and backhaul. ### Will it work with O2 or Vodafone? No. The W300 is a Band 1 (2100 MHz) booster optimised for all UK networks. O2 and Vodafone primarily use Band 8 (900 MHz) for calls and Band 20 (800 MHz) for 3G. For O2/Vodafone, choose the Boost4U C250 (Band 20 3G) or G250 (Band 8 calls). ### What size property does the W300 cover? Up to 300 m², which is typically a 3–5 bedroom house, a small office, a shop or a pub. Actual coverage depends on outdoor signal strength, building materials and antenna placement. For properties over 300 m², consider the C500 (500 m²) or C1000 (1000 m²). ### Is the W300 legal in the UK? Yes. The W300 is Ofcom licence-exempt with UKCA/CE certification. It operates within Ofcom's power limits and includes automatic gain control (AGC) to prevent interference to the mobile network. Legal for home and business use without a licence. ### How much does the W300 cost? £183.82 GBP including the booster, outdoor antenna, indoor antenna, 10 m cable, UK power adapter, mounting brackets and user manual. Free UK shipping. Optional upgrades: 20 m cable, high-gain antenna, surge protector. ### What if there is no signal outside my house? The W300 can only amplify existing signal — it cannot create signal from nothing. You need at least 1–2 bars of outdoor EE Band 1 signal. If you have 0 bars everywhere outside, contact EE to report a coverage issue — no consumer booster can help in that situation. ### How many phones can use the W300 at once? Up to 30 simultaneous users. This is sufficient for most households and small businesses. The booster amplifies the signal for all devices in range, not a fixed number — all 25 can be on calls or data simultaneously. ### What is the return policy? The W300 comes with a 365-day money-back guarantee. If you are not satisfied for any reason within 365 days of purchase, return the unit for a full refund (minus shipping costs). This is the longest return policy in the UK signal booster market. ### How long does delivery take? Standard UK delivery is 10–15 business days with free shipping. Express delivery may be available at checkout for an additional fee. The W300 is shipped from the UK warehouse. ## Related Blog Articles - [Best Mobile Signal Booster for all networks UK 2025 — Comparison & Reviews](https://www.ukmobilebooster.com/en-gb/blogs/news/w300-best-mobile-signal-booster-for-all-networks-uk-2025-complete-comparison-reviews) - [Boost4U W300 Review UK — 3G Call Booster Tested](https://www.ukmobilebooster.com/en-gb/blogs/news/boost4u-w300-review-uk-3g-call-booster-tested-for-21-days) - [How to Boost 3G Signal at Home — 300m² Complete Guide](https://www.ukmobilebooster.com/en-gb/blogs/news/how-to-boost-3g-signal-at-home-300-m-complete-guide-uk) - [Band 1 2100MHz Signal Booster for all networks BT ASDA UK — Full Guide](https://www.ukmobilebooster.com/en-gb/blogs/news/w300-band-1-2100-mhz-signal-booster-for-all-networks-bt-asda-uk-complete-technical-guide) Tags: Mobile Signal Booster for all networks 300m² UK buy EE mobile signal booster UK, best 3G signal booster for home 2025, 3G booster price UK, W300 mobile signal booster buy, all networks 3G signal booster deal, cheap 3G signal booster 300m2, EE mobile repeater for sale UK, Band 1 2100MHz booster purchase, 3G signal booster free shipping UK, Boost4U W300 discount, EE calls and 3G booster UK, mobile signal booster for all networks under £200 how to boost 3G signal at home, why is 3G signal so bad in my house, EE Band 1 2100MHz explained, does 3G signal booster work, how to improve 3G signal indoors, EE no signal in house solution, best way to boost EE mobile signal, 3G 3G dual band booster guide, mobile signal booster for all networks how it works, 3G signal booster installation guide, Ofcom legal EE booster UK, EE WiFi calling vs signal booster W300 vs C250 signal booster, EE booster vs Vodafone booster UK, best 3G signal booster vs O2, Band 1 vs Band 20 booster UK, W300 vs weBoost EE, 3G signal booster vs femtocell, Boost4U W300 vs C200, mobile signal booster EE vs Three, 300m2 EE booster comparison, 3G booster vs WiFi calling, W300 review vs alternatives, best mobile signal booster for all networks UK 2025 W300 3G signal booster, universal 3G booster UK, Band 1 2100MHz booster, all networks 3G repeater, 300m2 mobile booster, Boost4U W300, EE O2 Vodafone Three booster ## Details - **Price:** 183.82 GBP - 303.82 GBP - **Vendor:** UKMobileBooster.com - **Type:** United Kingdom - **Tags:** application 3G Data, coverage up to 300 sq metres, frequency 2100MHz, gb 1p, gb asda, gb bt, gb ee, gb freedom pop, gb gb, gb giffgaff, gb id, gb lebara, gb lycamobile, gb o2, gb orange, gb plusnet, gb sky, gb smarty, gb t-mobile, gb talkmobile, gb talktalk, gb tesco, gb The People's Operator, gb three, gb virgin, gb vodafone, has_stock_countdown, provider 1p mobile, provider Asda, provider BT, provider EE, provider Freedom Pop, provider giffgaff, provider iD Mobile, provider Lebara, provider Lycamobile, provider O2, provider Orange, provider Plusnet, provider Sky Mobile, provider Smarty Mobile, provider T-Mobile, provider Talk Mobile, provider TalkTalk, provider Tesco, provider The People's Operator, provider Three, provider Virgin, provider Vodafone, sale ## Variants | Variant | Price | Available | |---------|-------|-----------| | No / No / No | 183.82 GBP | In stock | | No / No / Yes | 203.82 GBP | In stock | | No / Yes / No | 233.82 GBP | In stock | | No / Yes / Yes | 253.82 GBP | In stock | | 20 M / No / No | 203.82 GBP | In stock | | 20 M / No / Yes | 223.82 GBP | In stock | | 20 M / Yes / No | 253.82 GBP | In stock | | 20 M / Yes / Yes | 273.82 GBP | In stock | | 30 M / No / No | 213.82 GBP | In stock | | 30 M / No / Yes | 233.82 GBP | In stock | | 30 M / Yes / No | 263.82 GBP | In stock | | 30 M / Yes / Yes | 283.82 GBP | In stock | | 40 M / No / No | 223.82 GBP | In stock | | 40 M / No / Yes | 243.82 GBP | In stock | | 40 M / Yes / No | 273.82 GBP | In stock | | 40 M / Yes / Yes | 293.82 GBP | In stock | | 50 M / No / No | 233.82 GBP | In stock | | 50 M / No / Yes | 253.82 GBP | In stock | | 50 M / Yes / No | 283.82 GBP | In stock | | 50 M / Yes / Yes | 303.82 GBP | In stock | ## Images - A mobile signal booster kit including various components such as an amplifying module, external antenna, cables, and installation accessories.
