@mckinley@twtxt.net Yes, I’m still with jmp.chat, and still very happy with them overall. Their beta period ended and their pricing increased a bit, so that’s worth a bit of consideration. I also managed to get one of their eSIMs. I’m slightly less happy with that aspect of their service, though they seem to be actively working on improving it and I knew in advance this was an early beta kind of thing and likely to have issues.

The only unreliability with calls that I’ve noticed was traceable to the unreliability of my own internet connection. I’ve confused incoming calls by simultaneously making and taking calls from the computer and the phone, but I think it’s understandable that problems might arise and that’s not a real use case for me. Once or twice I did not receive a text transcription of a voice mail, but the support is usually quick to address things like that.

I host my own XMPP server and have for a good decade now, and that’s what I use with jmp.chat. I can’t speak to the quality of their hosting options.

Group texting works fine for me if one of the other parties initiates the group text. I haven’t tried to initiate my own group text in well over a year; last time I did, it didn’t work. That may or may not be a problem for you, and it may or may not have been fixed by now. Worth investigating more if it’s important. I should also say I’ve only ever used group texts with 3 participants, and can’t speak to what happens if there are more nor whether there are upper limits.

Group texts don’t use MUC. Rather, they use a special syntax in the JID, something like “+1XXX,+1YYY,…,+1ZZZ@cheogram.com”, where the + and , are required, the XXX, YYY, through ZZZ are the phone numbers (no dashes or other special chars just digits), and the @cheogram.com at the end is required.

I recommend the cheogram app if you’re on android. It has a lot of nice features on top of the Conversations base. I use gajim on my (linux) computer and it works well with jmp.chat.

I’m happy to answer other questions if you have them!

@abucci@anthony.buc.ci Are there any (relatively easy (not having to implement it yourself)) alternatives to jmp.chat?

If there aren’t, could you please mention other alternative that there are? (even if you have to do some manual setup with some providers)
(I guess this would be a possible oportunity to start a company that
offered jmp.chat’s functionality for other countries, (I guess having
different companies that are managed by different people for the service
of different countries (the same as jmp.chat more or less), would
encourgeage competition, but not sure))

Asking because I live in a different country, so even if I did register
to jmp.chat, the system would probably not let me send messages and or
calls to it, as it’d be a crazy expensive call or message, right?
And even if I could, calling that number would be expensive for family
and/or friends, and/or other people.

Though, being fair with myself, I think they wanted to expand to more regions, but I guess that if I tried to setup a company to offer something like jmp.chat, I’d have to track my users, (at least know their identificative documents), as that’s written into law here in the EU.

@abucci@anthony.buc.ci Thanks.
