One of the worst networks in the market right now. I've been with them for over 4 years. The network used to be good. But for the past 2 months it has been the worst it's ever been. Today was my breaking point - I am now so fed up of this network and of their customer service. Trying to get my sim issue resolved was one of the hardest things ever for no reason. They made me continuously repeat the troubleshooting steps - again and again and again. The process they incorporate as a business is appalling. The support I get from them is appalling. Their network is appalling. I can't even get 4G in my own home. By far the worst experience I've ever had with Tesco Mobile. It's a shame to see that they have fallen off this badly - what once use to be a really good network has now become one of the worst in the UK. They are taking my money every month and I'm not getting anything of value from it. I would DEFINITELY NOT recommend this network.
