My niece has an old iphone with no SIM/phone number. Only wifi internet access.
Looking for an app for both of us to be able to chat
She cant chat with me over signal because no phonee number. She chats with the rest of the family over imessage, but i have an android phone
Is there an app available for both android and iphone to let me chat with her?
Thanks
Edit: willing to self-host for extra privacy. My nieces and nephews are all young children so i definitely want to encourage/educate them to get off corporate controlled communications channels
Jabber (XMPP) or Matrix/Element.
Https://snikket.org will get you started with XMPP easily.
Conversations on Android and Siskin on iOS.
One non-techie parent has Siskin running on their iPhone and it hasn’t skipped a beat in years of messaging using omemo-encrypted XMPP. For servers, they’re on tigase.im and I’m on conversations.im.
Here’s a guide on optimum siskin settings; I don’t know if defaults are better now or not.
Conversations.im is free on fdroid but it’s well worth paying something to the developer directly.
