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

      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!

        That gets really complicated with room keys and stuff though. So it’s not particularly user friendly.

    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”

    You can use a voip/sms service to register with the traditional messaging apps: signal, telegram, etc

    I.e. google voice, or https://kycnot.me/search?q=sms&type=

    Though I think :

    Matrix, simplex, and briar are good options that don’t need sms at all

    FYI, last week someone saw that Signal merged in code for username (no phone number) support. So it might not be long until you see a beta release which allows you to sign up without a phone number.

    Threema.

    It costs $5 dollars, so you’re less likely to be the product. Highly private. Includes some open source code. Audited. Android and iOS. Doesn’t require phone number.

    Here are the settings I recommend during first setup: Tap next instead of making a Threema Safe password Tap next instead of entering your phone number Turn off “Sync contacts”

    Signal v7 with username IDs is right around the corner. I’d suggest you wait a few weeks if you can.

    With Signal you only need a SIM card to register the account via the Signal app on the phone. You can receive the SMS for registering on another phone. After registering you can simply use Signal over WiFi. If this is too difficult, XMPP with a good OMEMO client for E2EE is an option. Easiest to install and start with is perhaps DeltaChat, E2EE chat via email : https://delta.chat/en/ You only need to learn what to do if the E2EE is not working right away. They have a FAQ and hints in the app.

      if you use textfree, you can probably register on signal with a fake-as-fuck phone number. but i think textfree requires a valid phone number for that.
      very sucky to have to do all that.

    I’ve used a self hosted Nextcloud for that. It’s not great but it worked well enough that I didn’t bother looking for better alternatives. I’m sure there are more options out there.

      Hmmmm… I already have a nextcloud instance running… This is probably the most frictionless option for me…

      I’ll look into NC talk on iphone for her. Thanks!
