F.A.Q.

Does Bimba work in X?
Places, networks, operators supported by Bimba are listed on wiki and those supported via Transitous are listed on their website
What is advanced configuration? What is server and token?
Bimba is not a walled garden, you can use other server if you don’t want to use the default. No servers in the wild are known, but you can host your own instance of szczanieckiej.
Tokens are given only to a small group of personally known people. They allow circumventing rate-limiting. In your own server, they may be used in whatever way you see fitting.
There are plans to replace advanced configuration—including tokens—with better UX, which will still retain current freedom.
