3g Vodafone network is driving my crazy, it is very slow and unreliable at peak times so I am thinking of switching to 4g phone on EE.

Can anybody comment on their 4g experience on any network in London, and possibly EE's 3g as well? How often does your phone stay on 4g, is it faster and more reliable than 3g when it comes to internet connection?

40mb up & down in Kingston & similar throughout central London from my experience on EE

Thanks, that's useful.
