I am looking for a reliable and preferably privacy oriented alternative to Skype credit - a service that allows me to call landlines and mobile phones via an app or website. I’ve heard of Yadaphone and Yolla, but I don’t know much about them. Do you guys have any experience with these? Do you have other recommendations?
Jmp.chat is very cool. It is a $5 month subscription and gives you a US or Canadian phone number for texting and calling. The app it works best with, Cheogram, is also FOSS. I think it works with all XMPP/Jabber clients though. They will also host an Snikket instance for you with your subscription if you request it.
