But your question was what the 4G speed is. All these high ones are via FTTx routers and WiFi, which is nothing to do with your question.

I see others have responded. I don't tend to do speed tests on mobile because so much depends on where you are - I'm sure if I was in London it would be amazing but in my little City things are probably different - especially since we don't have the same density of coverage.

However, just done a check on speedtest.net and got 33.41Mbps don and 15.96Mbps up. That's on a Google Nexus 5 with Lollipop.

General performance though is so much better than on my old so called 3G with O2.
