Obviously a lot of people are having problems with Three at the moment, especially with the Xbox, but just to give a bit of balance, Three and their unlimited SIMs have worked really well for me. Just tested my speed at 19:20 on a Saturday evening in the midst of a UK semi lock down and I'm still getting over 30Mbps down and a bit more than that up. And that's costing me less than £18/month. I know that's no help to those who are suffering poor connectivity, but to anyone who thinks Three is complete crap - they aren't!
