Most mobile hotspots or WiFi repeaters such as Comcast's Xfinity require that you run a browser and provide your account info and after authentication they pass you on to the Internet. This technique is called "Captive Portal."

You "may" be able to connect to your cellphone if it provides a WiFi gateway... I have not tried this.
But, in general, the ESP8266 connects to an Access Point via a stored WiFi SSID and Password.

There has been several discussions of this concern in the forum previously...
