iPhone FaceTime and messages

Hi Youngmessi10,

Welcome to Apple Support Communities. Since your messages appear in green, iMessage and FaceTime may be disabled or temporarily unavailable. We'd recommend starting with the guidance in If you can't send or receive messages on your iPhone or iPad. Below are a couple sections which might be particularly helpful.

"If you have issues with Messages after you set up a new device

If you experience issues like conversations in Messages showing up as separate threads or sent messages appearing as green message bubbles instead of blue message bubbles when you set up a new device, update your settings using the following steps:

1. Update your device to the latest version of iOS or iPadOS if needed.
2. In the Settings app, tap Cellular. Make sure that your phone line is turned on. If you use multiple SIMs, make sure that the phone number you want to use is selected and turned on.
3. In the Settings app, tap Messages. Turn iMessage off and then back on.
4. Tap Send & Receive.
5. Tap the phone number that you want to use with Messages.

If you have issues when you try to receive a FaceTime call after you set up a new device, you can also update your FaceTime settings."

"If you see a green message bubble

If you see a green message bubble instead of a blue one, then that message was sent using MMS/SMS instead of iMessage. There are several reasons for this:

• The person that you sent the message to doesn't have an Apple device.
• iMessage is turned off on your device or on your recipient’s device. To check if iMessage is turned on for your device, go to Settings > Messages > iMessage.
• iMessage is temporarily unavailable on your device or on your recipient’s device.
• You might need to update your settings for Messages after you set up a new device."

If any error messages appear during those steps, what do they say?

All the best.
