From reading this board, it appears to be a common theme - but my 4G is now massively slower with the new sim card that was sent to me last week than it was with the old one.
Nothing has changed other than the sim card, same device, same settings etc.
However, my average speed has dropped from between 12 and 15Mbps, to between 0.1 and 3Mbps.
The coverage checker on the virgin site suggests I should have good indoor speeds in my area, and within the house - we do have people on Vodafone, O2 and EE - which are all getting much higher speeds. So I don't believe it is a coverage issue.
Is the new network intentionally slower, or are there new APN settings or similar that I should be using does anybody know?
