I totally agree with your comment about apps unusable with poor connections. I've been away camping for a few days, the campsite was in a forest with a weak 2G connection; web pages would load slowly, so the link did work, but most apps gave up and timed out instead of using the connection. A chat app like Google Hangouts should be able to send and receive tiny text messages just fine over 2G, but apparently app developers put in too short timeouts.

Yep. Apps like Hotels.com app and BA apps time out while the sites work fine on 2G. App devs think everyone has big data pipes; I almost never do. At which point Wechat is great.
