My iPad texts are not synching with my phone!

Have you set up Continuity to receive the texts on both devices? Or, have you set up using iCloud messages? Use Continuity to connect your Mac, iPhone, iPad, and Apple Watch - Apple Support That is two different things. Also, if using iCloud messages, the messages will arrive on both devices, and if you delete a message on one device, it will delete them on all devices. Set up iCloud for Messages on all your devices - Apple Support
