Nope, you don't have to pay for a certificate at one of the traditional CAs, you can use Let's Encrypt to have free but fully valid certificates for your server.
See https://letsencrypt.org/ for more information. I can recommend https://github.com/xenolf/lego for use on your server, but there are many different LE clients out there.
If your phone does not already trust Let's Encrypt's CAs, you should be able to install their certificates to get it working. I suggest you start by getting a cert onto your server and take it from there though.
