Is 3 throttling vpn connection?

[Ferry]

With work VPN off I get 340 MBps and with VPN on I get 5.8 Mbps. This is not usable for work. Can someone please check and confirm the throttling policy? Starting to happen this week

Every time you use a VPN you get a speed drop this is not unusual. See if you can change what server the VPN connects to and try a few different ones to see which is fastest.

Three have a system called trafficsence which will only affect your speeds if your data use is considered excessive. I can’t remember the figure but the bar is set very high. I use a lot of data (probably in excess of 100gb each month) and I’ve never knowingly been affected. To the best of my knowledge,Three don’t routinely throttle connections.

Actually I managed to workaround this by switching from UDP to TCP for VPN so 
VPN off: 440 Mbps
VPN with UDP: 7.6 Mbps
VPN with TCP:45 Mbps

Not great but at least this is usable for work. And this is just zoom calls and not large data use

Whatever works is good. 👏
