Ways of connecting to Xbox Live!

Hey there Gazza. First off, HUGE congrats on moving in with your SO. Best move of my life, and I wish you all the best. As for your connection, that is a sadder story. For now there is no supported method of connecting a dongle for networking purposes. If you are using a phone as your 4G device it SHOULD be possible to create a wifi hotspot and then connect your console to that wirelessly. It is not going to be an amazing connection (more than likely will see lag issues in game causes by the instability of the connection type), but might be enough to stay connected depending on the quality of your 4G connection. 2 Mb internet connections are high enough to support an Xbox Live connection so you might actually be fine with your internet service provider, but if not it sounds like you could have a hotspot alternative. Best of luck.

I use a 4G hotspot and it does work, however, you will have a Strict NAT which can make it hard to connect to chats reliably and you will see some lag.  At this time it seems that using an iPhone (wi-fi or via USB) to connect isn't possible so you would have to use a hotspot accessory in that case.
