It's not. My goal is to make VoIP calls, share my location with friends (some of whom don't use wechat), and just browse web pages. All of which is difficult to do when the data connection keeps dropping.

I actually did have problems with wechat location sharing when a friend tried to share his location with me. I had set VPN.ac, which I was using that day, to allow wechat to bypass the VPN, figuring that since it is a Chinese app, it shouldn't need to use the VPN. But it was trying to pull data from Google Maps, so it didn't show anything except two dots on a blank background (until I switched the VPN on for wechat too).
