How to open wifi by texting? It seems that there is only WLAN.

Wifi does not need to be turned on because it is a wireless connection. As long as you have a free wlan or a wlan with a password you know, you can turn on wifi to log in to wlan. Unlike the wlan just mentioned, the mobile wlan is a large-scale Wlan made by a mobile company and needs to be opened for a fee.

I think your so-called wifi means you want to surf the Internet directly through your mobile phone card. You can call 10086 for consultation. (2G data service or wlan service can be opened. )
