I recently signed up for unlimited data package so that I can video stream for work. I'm shocked to see that I am not even getting 4g in Leyton, just H+! The download speed in just over 2mbps and the upload speed is much worse. Is this a wide ranging issue in Leyton or just the street I am on? Is there a solution provided by Virgin for this?
If you've just signed up to Virgin Mobile you will probably be using Vodafone.
It's hard to say without a more precise location but in general Leyton looks well served by 4G, there are a lot of masts in the area and most of them transmit on multiple bands too, so coverage should be good (even indoors).
I can see on the Vodafone checker that there is a problem with a mast at E10 5BY which is perhaps affecting your service if that is close to you.
