So I have a really random issue which is seemingly related to the Vodafone network...

I recently bought an Orvibo Allone IR remote which can be operated over 3G. It works fine on 2-degrees but I just get timeouts on the Vodafone (3G) network.

I've tried two 2-degrees SIMs and the "cloud" connection over 3G works fine.

Tried the same thing on two different Vodafone SIMs and and the "cloud" connection over 3G doesn't work.

Now I believe the app does a HTTP handshake and then sends some UDP.

Are there any firewalls/restrictions on the Vodafone network that would cause this kind of issue?

PS I dont have this kind of issue with my WeMo, Ergo or Limitless kit.
