Currently looking at:

• jmp.chat with the Cheogram app - at $3 a month for each number, it’s a little pricey.
• VoIP.ms with either the linphone app or one of the other FOSS apps in their softphones list - $0.85 a month but calls and messages are a la carte, which is not my favorite but it’s less expensive.

I know a lot of people like using MySudo or Grandstream, but I’d like to keep it FOSS and not reliant on google play services if possible. Battery considerations are also a plus.

So what are you using and would you recommend it?
