The 2G and 4G booster is ideally what you need to enhance your internet coverage. It is designed both for voice and data networks and operates within 800, 900, and 1800 MHz network frequencies. It has coverage of up to 1-2 rooms and should, therefore, suffice for small apartments and offices. If well maintained and run correctly, it can serve you for ages. All you have to do is stick with the procedures provided in the manual. Moreover, it can be used for all the major UK mobile operators like O2, EE, Three, Vodafone, Orange, T-Mobile, BT, GiffGaff, TalkTalk, Tesco Mobile, and Virgin. With the standard model, your devices will ooze up to 5 bars of signal, in case the original signal outside is 4-5 bars.
