Nick Baker (UK, Leeds)
I am really happy that I decided to order a booster on UKMobileBooster.com. Due to the pandemic of coronavirus, we have taken a decision to stay at home. But of course, in our case self-isolation could have presupposed full isolation from the whole world as the quality of our mobile signal at home used to leave much to desire.
In home O2 signal booster is a perfect solution for small cottages.
Mark Smith (UK, Wigston)
I would recommend this booster to anyone, because it’s a really good option for small cottages, the price is very adequate, and the whole system itself is safe and compact. It doesn’t waste a lot of energy while it’s working, and turns off automatically when not used, and I noticed that it actually saves the battery of my phone.

How I managed to solve my Vodafone mobile phone signal problems
Peter Barrett (UK, Somerset)
If you are fed up with mobile signal issues, try to use GBC100. We like it! I would definitely recommend this device (or other products of this seller) to anyone facing the same EE 4G signal problems in the UK. The device is really worth the price!
