Freedome working over wifi, but not 3G
I recently installed Freedome on an iphone 4 on ios 7.1.2 and have been using it over wifi connections with no problems. However, once I'm away from a wifi connection and on 3G, the connection drops. I've reinstalled the app, reset the network connection on the phone, turned airplane mode on/off, switched VPN to manual (needed to connect to wifi to download the new profile) and despite trying each of these the 3G data transfer is dead whether VPN is manual (off/on) or automatic. The only way to get the phone to download data over 3G is to remove the Freedome app entirely and restart the phone.
I was wondering if it's possible to get some help with this - I couldn't immediately see a simialar query from searches, they seemed to be more 3G working but wifi not working, and I have the opposite problem. I had similar problems (3G trying but failing to download data) when using Onavo extend in the past - no idea if that's relevant!
Thanks in advance for any advice/help.
