Hi SasaGma,
We see you're having an issue with Messages. To clarify, is it saying the recipients phone number isn't registered or yours? If you're using an iPad and you're trying to send a message to someone who doesn't have an iPhone, you'll need to use text message forwarding from an iPhone to do so. Learn more here: How to forward SMS/MMS text messages from your iPhone to your iPad, iPod touch or Mac
We hope this helps.
Take care.
