Three network coverage is total crap and I am not even sorry for these harsh words. I was stupid enough to sing up for a 24 month contract because I just moved to the UK and did not research mobile operators well enough. I also have 2 SIM cards with Three, which doubles the trouble.
Network coverage is close to non existing. When outdoors in the very center of London it kinda works, but going just a bit on the outskirts, such as Hamstead, Shepherd's Bush, Richmond or wherever I barely get 1 or 2 bars. Trying to plan a route on google maps while being on the street? Make sure you take a few steps in the direction where you have just enough internet to serve your needs. Trying to use internet indoors is out of question. Wanna go to the restaurant? Make sure you google for images of the dishes before you enter, because no internet will be served for you inside! 5G coverage across London? I barely get 4G anywhere I go!
Trying to resolve issues the nice way also did not help. On top of technical problems, the customer service ignorance is astonishing. I actually have a quote ref (*******) which is a disgrace. This is not the first time I complained, but the first one which triggered me. I called them to say I want to leave Three because of the network coverage. I got a bunch of non-sense suggestions, such as reset your network settings, close all apps, restart phone, etc. We are living in the 21st century and are still struggling to provide normal service without telling customer to switch on/off? Then Three asked me which postcode I am in. Stop. Really? What is this question about? It has nothing to do with the quality of service. Anyways, I was at Shepherd's Bush, so I told them the post code. You will not believe it, but then Three told me that there is some maintenance work happening at this postcode and I need to wait for a month until it gets resolved and they advised me to use WiFi in the meantime. I replied that this is nonsense. Then Three got disconnected and I received an SMS saying that my complain was resolved. NO. That is total crap, my case is NOT resolved. I have used many other providers in different EU countries, nothing comes close to this crap. If I complain about the network coverage in general why even bother asking me for the specific postcode? Do you see me living my whole life within one block? Am I not allowed to leave my postcode area? Why did I even get a SIM if all I do is sit at home? Guess what, I am constantly traveling around UK & EU and I need internet everywhere I go. I know they have been instructed to talk down customers so they cannot leave Thee, but they brought it to a whole new level.
