iMessage issue

A couple of things you can try.

• Sign out of iMessage and sign back in.
• Put your phone in airplane mode, wait a minute then turn airplane mode off.
• Reset your network settings. Settings>General>Reset>Reset Network Settings. You'll lose saved WiFi passwords but that's all
• Delete a conversation with someone who you used to be able to iMessage and start a new one.

My iMessage does not appear to be working. Since last night my bubbles are green to other iPhone users. I did the update, and made sure iMessage was on in settings.

Do you have an active data connection (either WiFi or cellular)? Do the people you're sending messages to have an active data connection?

Please see the pic below. Do you see the message?

Glad it helped!
