After looking around their website I found the info on SMS. I do like that it has a minimum pay of $5, both VoIP.ms and JMP require $15 to start. Although, I saw for SMS KeepCalling directs you to their app on the play store. I wonder if it is possible to use their SMS service with a third party app? I would like to avoid using apps from the Play Store if I can help it. Otherwise, it might be a viable option to try out with such a low barrier to entry. I’m still leaning JMP since it seems like the easiest to setup and use between mobile and desktop (MX Linux in my case, using the Gajim app).

Ah, that’s a clever way to circumvent minutes. Signal can only call other Signal users, right? So, if I wanted to call my mom, for instance, she’d need to get Signal? It’s been a sec since I used it.

Does KeepCalling have SMS included?

JMP did look like it was much more straightforward to setup than VoIP.ms. The configuration of VoIP.ms looked pretty bewildering from reading the wiki. My only concern with JMP was the minutes. From what I read it said it was unlimited text but only 120 min/month. Is that accurate?
