My FaceTime only works on wifi. Why is that?

Hi Kissa24,

For help with using FaceTime over cellular data, check that your current carrier supports the feature with the help of the website here: Wireless carrier support and features for iPhone

If your carrier is listed and supports the feature, start with the steps below found in the article here: If you can't make or receive a FaceTime call on your iPhone or iPad - Apple Support

"Update your FaceTime settings after you set up a new device

If you experience issues with receiving a FaceTime call after set up, update your device with 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 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 FaceTime. Turn FaceTime off and then back on.
4. Tap the phone number that you want to use with FaceTime."

If the issue continues, follow the remaining steps in the article. Reach out to Apple Support directly if you need further assistance.
