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
Matrix / element
To expand with my personal experience, I self host a synapse server partly for the reason that i want my children (aged 8-14 now) to have a communication platform they can access to get ahold of me with out requireing a sim card. I do not federate, and i do not allow account sign ups. That keeps a pretty isolated instance while still allowing everyone on that homeserver to be able to talk to each other.
I help them get Element setup on each device. I dont think this is overly complicated, but i am sure i am a horrible judge of complexity… They have to enter the url of the server, then their password, then they need to scan a qr code/verify from an existing device. Or, they need to enter a second passcode to verify their identity. I help them keep those secrets in bitwarden, so imo, that complexity is an opportunity to explain some opsec and encryption!
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.
My friends and I all use Simplex and have been very happy. There’s an annoying feature where messages in group chats are sometimes delivered out of order, but it’s easy enough to live with.
“I remember my uncle, he used to force us to use some janky app to talk to him because he was afraid of the big corporations spying on him”
Except they literally do. It’s even acknowledged in the mainstream media.

What’s frightening is that people more or less agree with this, but they have apathy to the point of making up excuses for it. Humanity is remarkably adaptable, and if they can adapt to supporting slavery or genocide, they will and they still do. Never mind things that are less terrible.
