I heard about jmp.chat recently, and I decided to give it a go. It’s a cellular provider that sends all communication over wifi, and it’s freedom software! You can pay jmp for this service, or you could install your own jmp server and run it yourself!
So why use JMP? Do you want to support freedom software? Do you like the idea of sending and receiving communication via freedom software? If you do then give it a try. You’ll learn about XMPP, which is a federated instant messaging protocol. You’ll also save a lot on your phone bill, because JMP only costs $3 a month!
