> It’s impossible for a 3rd party smartwatch to send text messages From Apple's docs: https://support.apple.com/en-us/102842 https://support.apple.com/en-us/102842 "Message Access Profile (MAP 1.4) This profile is compatible with iPhone 5s and later. Message Access Profile allows devices to exchange messages. It's used to receive incoming message notifications on connected vehicles. iOS and iPadOS support these MAP functions on connected vehicles: - Receive incoming message notifications - Reply to incoming messages - Compose new messages - Browse message inbox - Mark messages as read" The documentation talks about "connected vehicles", but can totally be implemented by any Bluetooth accessory.

  It's been a little while since I've worked in the space, but it's worth checking a newer revision as this wording may no longer be present https://developer.apple.com/accessories/Accessory-Design-Guidelines.pdf https://developer.apple.com/accessories/Accessory-Design-Gui... From a technical standpoint, there is no limitation for an accessory to implement the profile.

    Yeah, the profile supports it, but Apple doesn’t support all the implementations as outlined in the profile. I’ve been barking up this tree for nearly a decade.

        If you can produce a working proof of concept for sending sms or iMessages from a third party Bluetooth device with MAP on current iOS, I’ll follow you anywhere captain.
