Just moved to o2 and have noticed that Internet based calls (voice and video) are pretty much unusable, been running tests and it seems the upload speed struggles to even get above 2Mbps.
Coming from EE, where I would get 30-60Mbps upload, on 4G, this seems very poor and is in fact the slowest upload I've seen on any major network.
It isn't just isolated to the area I live either, the same speeds are seen within the City.
Is this a national thing with the upload or is it isolated to this county? Are there plans to improve this? I don't mean improve by waiting for the 5G rollout either, this should be improved on the 4G network to compete with others.
