After updating to OneUI 7.0 I started getting issues with my JIO Sim.
Sometimes it goes to Emergency calls only in a good ntw area. And once I turn on and off Airplane mode the SIM gets unregistered from the device and the notification bar show only my Airtel SIM.
The only solution is to reboot the device.
Also the wifi calling on JIO sim gets turned off automatically in minutes after me turning it On.
Happens everyday.
Sometimes on wifi calling I get no ntw registered error.
2. Galaxy device wi-fi issue: The Wi-Fi Calling feature may not be available depending on the country and carrier. Please check if the Wi-Fi is turned on and the SIM card inserted that supports the feature from the network provider.
● Follow the below steps to turn on Wi-Fi Calling:
● Turn on Wi-Fi Calling: 1. Go to Settings. Tap Connections, then tap Wi-Fi Calling.
2. Tap the switch to turn the feature on. If you see a popup asking for your emergency contact information, please enter it and tap Save. You need to be connected to Wi-Fi and have active service via a SIM or eSIM to enable Wi-Fi Calling.
3. Wi-Fi calling is now enabled. To turn it off, tap the switch again.
4. On some phones, you can also enable Wi-Fi Calling from the Quick settings panel. Swipe down from the top of the screen with two fingers, and tap the Wi-Fi Calling icon.
5. To update your emergency information later, go to Wi-Fi Calling and tap Emergency Address.
● Wi-Fi Calling settings: 1. You can set preferences for calls when your cellular network or Wi-Fi is unavailable.
2. Go to Settings, then tap Connections, then tap Wi-Fi Calling. On some carriers, you might need to tap Roaming network preference or When Roaming.
3. These settings are only available when Wi-Fi Calling is on: Calling Preference: Choose Wi-Fi calling or your cellular network. If your preferred network isn't available, the other will be used automatically. Emergency address: Update the address your carrier has on file for emergency services.
● Trouble with Wi-Fi Calling? ● If Wi-Fi calling isn't working, check these things:
● Wi-Fi Connection: Make sure you're connected to a strong Wi-Fi network. Check the Wi-Fi icon in the Quick settings panel (swipe down from the top of the screen with two fingers).
● SIM Card: Ensure your SIM card is inserted or your eSIM is active. Your address should be updated in case of emergencies. You can also check if your phone’s operating system supports the feature.
● If these steps don't help, contact your carrier. Note: Wi-Fi Calling may not be available on all carriers or devices.
