No roaming data on my iPhone 11, iOS 16

Welcome Quentindvl,

Thanks for posting in Apple Support Communities. We understand that you do not have the Data Roaming option in the Settings app. To clarify, did this option appear before? Also, do you and your girlfriend have the same carrier? We ask because your iPhone settings could vary when you're using another carrier.

However, this option should be available on your device. We'd like to provide you with a few steps that may help resolve the issue:

• Restart your iPhone:

1. Press and hold either volume button and the side button until the power-off slider appears.

2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.

3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo.

• Manually update your carrier settings on your iPhone

1. Make sure that your device is connected to Wi-Fi or a cellular network.

2. Tap Settings > General > About.

3. Follow the onscreen instructions to install your carrier update.

If you insert a new SIM card into your iPhone or iPad, you need to download the carrier settings for your new carrier.

To see the version of carrier settings on your device, tap Settings > General > About and look next to Carrier. To see additional carrier information, tap the version number. To verify that you have the latest carrier settings installed, contact your carrier.

Let us know if this helps.

Take care.
