Want to use your Android phone without a carrier? It is possible. Here's how to make and receive calls using Cheogram, JMP, and XMPP.

All of that is pretty much useless if you dont have access to a wifi.

i do almost exactly this not to replace my carrier, but for the sake of being able to call and text my homeland from abroad. jmp.chat is a great service for what it is.

well well well, us registered company? or where can i see a details or at least a details about this soprani.ca company?, us registered domain, under cloudflare, not really free speech, what else is runnimg under the cloudflare? the application? quite useless with net connection and you anyway heavy rely on 3rd party, buy api for sms or jabber … that also really free speech and totally out of your control. and the page looks like shit, at least try to sell it. the isp product is so heavily rooted in our society that we need to give a different approach, like our grand parents got, find a time for a people you love and see then face to face.

Its all open source, you can self-host it. But I agree, it is more useful for US or Canada based users given the limited selection of country codes.

Its all open source, you can self-host it.

I know that there are components required to provide this service that are open source and/or self-hostable (eg - XMPP server and XMPP client). However, in the (very) little digging I’ve done, I don’t see how you could self-host the ability to receive a phone number (and to a lesser extent, call/text using that phone number).

Are you able to self-host the components necessary to obtain and use a phone number? If so, is the cost (omitting any hardware acquisition or hardware operations cost) any different than paying for this service or are there any other non-hardware based limitations (eg - can only activate a certain quantity of phone numbers, can only place a certain number of calls, etc.)?

Yes it uses Astericks internally an you can hook that up to any voip service or even your own land-line or GSM modem. But to be honest the setup is quite involved and only for advanced sysadmins.
