Poor services will be a good remark --- Uniconnect has really got very bad network and customer services in London. There is no way that they are cheap and affordable as what they claim to be. The only good thing about them is that it’s a pre paid card, something that you can easily get rid of if it doesn’t work well. I had a frustrating time using a uniconnect sim in London so much so that I stopped using it completely. They were not only draining the money out of my account, but were really expensive. It made absolutely no sense to use their services at all.
