After starting ipfs daemon with pubsub enabeld on mobile with 4G network, we can’t connect to other node which is under Wifi network, and can’t find the file with the HASH got from the computer.

1. Is there any special configuration needed with 4G network?
2. Does it support 4G network? If not, Any plan to enhance this?

This is probably because your node on the WiFi network is behind a NAT. Go-ipfs will _try_ to break through the NAT but this isn’t always possible (although we’re getting better at this). If you want to try fixing this situation manually, you’ll have to forward port 4001 from your router to your IPFS node.
