Text messages

Hello

A green text bubble usually means it is sent from sms (said above), and the receiver of the text is on a non-Apple phone. If this is happening to all of your texts (even to Apple users), look in the messages part of settings, and see if it is correctly set up (as also said above). If that doesn’t work, just try and restarting your phone…or if it doesn’t work, contact Apple at this link: Contact - Official Apple Support

Hope this helps.

Take a look at Settings>messages to see if iMessage is correctly set up and turned on

If this is the case, restart your phone to see if the problem persists
