Question: iPhone
Hi my name is Nataly I've been having issues with my messages there going in green when everything on my settings is good and when someone with a iPhone texted me it turns blue again.
Hello and welcome to Apple Support Communities, nataly4747!
I understand you're seeing messages send with the green bubble but notice that when someone using an iPhone messages you, the bubbles are blue. I'd be happy to explain what is happening.
If you're messaging people using a device that is not an Apple device, the message bubbles will appear green. Otherwise, the bubbles are blue: About iMessage and SMS/MMS
I hope this clears things up.
Have a great day!
