I can’t send text messages within a current thread anymore from my iPad. I could a month ago. Now they show up green and won’t send.
How do I send text messages with my iPad and have them show up in blue?

You must verify that Text Message Forwarding is explicitly enabled for your iPad on your iPhone.
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

As the iPhone acts as a relay for your iPad to send/receive SMS messages, it follows that while “travelling” outside the area for which your iPhone has an active cellular contract and coverage, the iPhone must be able to “roam” to other cellular networks.
