Asking for a simple way to bypass time bassed free wifi (android). I'm on a travel trip

0/ I'm looking for a way to bypass or reset my time allowance on a WiFi network.
I'm Not looking to DL/stream any large files.

Just to extend my email and chat.

Android, not rooted. I guess it's a MAC log.

On a train if that helps. I only have 45 min a left.
