syncing

If you have an iPhone - and both iPad and iPhone are signed-in to iCloud with the same AppleID - to send SMS/MMS messages (green bubbles) from your iPad you must explicitly enable Text Message Forwarding for your iPad on your iPhone. Verify these settings:

On your iPhone:

Settings > Messages > Text Message Forwarding - set to ON - and explicitly enable your iPad from the list of devices.

Also ensure that Messages in iCloud is enabled on both your iPhone and iPad:

Settings > [Your Name / AppleID] > Messages - set to ON

Troubleshooting iMessage Inaccessibility:

If you are changing you Apple ID every-so-frequently, then disable iMessages, and then re-enable it. Do so in the settings on an iOS device. If this has to do with messages from your carrier, then contact your Carrier, as they are the one who provide you with the service of Messaging.
