Mobile-friendly XMPP Gateway to any SIP Provider — JMP Blog
(blog.jmp.chat)
Switched to their data-only sim with their gateway. Ported my number in and I'm super happy with the results.
Since this community was partially inaccessible due to a long standing bug in Lemmy, we moved to a new XMPP community here instead: !xmpp@slrpnk.net
XMPP/Jabber is the community-owned standard for real-time federated messaging.
