      I have moved in to a brand new build flat. I am with Tesco. The external mobile phone signal is fine. To receive or make calls from inside my flat I have to hold my phone out of the window. The house builders say that the reason why I can’t get a signal inside my flat is because it is so well soundproofed, fireproofed and insulated that a signal is prevented from getting through. Will your Pro Mobile Booster enable me to receive and make calls anywhere in my flat? Malcolm Day.

      • Dear Malcolm, Thank you very much for your question. Yes, it indeed can, but we need to check a few more things before guaranteeing it, so, please, check your inbox for a further discussion. Regards, Hellen Dupont Sales Specialist

          Hi, Thinking of buying your 4GLTD – 300 sqm unit for my holiday caravan. I have 60GB limited data on my Galaxy A21s phone.. Would this amount of data be enough to watch Netflix / I player on tv say 4/6 hours / month.

          • Dear Mr. Herbert, Thank youm I can see you have already ordered your best mobile booster. If you ever have any questions, feel free to refer to us anytime. Regards, Hellen Dupont Sales Specialist

            Mark Verified Customer2021/06/05

            Will this work in conjunction with a sim router to enable streaming on a smart tv

            • Dear Mark, Thank you very much for your question. The booster works by catching the signal from the cell tower using the given frequencies, and it can only improve the signal for all the devices which work with a sim card and accordingly works on the same frequencies. So, if the router has a sim with the general providers, then yes, the booster will work for it. Regards, Hellen Dupont Sales Specialist

                I live in an old farmhouse with very thick walls (2-3 ft). Would this work for me as only O2 can be reached outside and then only 2 bars maximum

                  David Ratcliffe Verified Customer2021/05/23

                  We have a static caravan in Llanbedrog on the Llyn Peninsular LL53 7NN, where the signal on our Giff Gaff phones is very unreliable, between 0 and 3 bars. Sometimes 3g and sometimes 4g. The site is hilly and has many trees and I don’t know in which idirection the O2 Transmitter mast is. We would like to run 2 Apple mobile phones, 2 i-pads, a wireless printer and TV. Please advise the best package to achieve this. Kind regards David Ratcliffe

                  • Thank you for the question and your interest We do have products for caravans as well and we have products with multi directional antennas which doe snot need to be pointed out to a certain direction Regards, Customer support team

                    David S Verified Customer2021/05/05

                    What are the power requirements for this booster? I’m looking to install one in a van using a 12v DC supply and a converter rather than the mains power supply that is included with the booster.

                    • Dear David, Thank you very much for your question. We can ship you an adaptor for 12v. I will email you to discuss it further. Regards, Hellen Dupont Sales Specialist

                      Nathaniel lewis Verified Customer2021/03/10

                      how much is it to HIRE AN EXPERT off this site to install my signal booster ?

                      • Dear Mr. Lewis, Thank you very much for your question. The installation price depends on the size of the building you will cover, the type of the booster you choose and your location. Please, check your inbox for further communication. Regards, Hellen Dupont Sales Specialist
