Samsung Phone All incoming calls coming as Private caller or unknow caller O2

We had a chat at o2 store with o2 staff and they confirmed that it is network issue which should resolve within 5 working days

After 7 working days, We called again on 17th October 2023 and We were informed that this issue will take another 10 working days.

Please do not buy another phone just try to use same sim card into any other phone you will have the same results. We received customer having same issue and unfortunately its the The o2 who needs to fix it. You dont need to buy another phone this will not resolve the issue.

1. Open the “Settings” app on your Samsung phone. You can usually find it in your app drawer or by swiping down from the top of the screen and tapping the gear-shaped icon in the top-right corner.
2. Scroll down and select “General management” or “System.”
3. Scroll further and tap on “Reset.”
4. Now, tap on “Reset network settings.”
5. You might be prompted to enter your device’s unlock method, such as a PIN, pattern, or password.
6. After entering the unlock method, you should see a warning that resetting network settings will remove all network-related configurations. Confirm that you want to proceed.
7. Your phone will reset the network settings. This might take a moment, and your device will reboot when it’s done.

Once your Samsung phone has restarted, you’ll need to reconfigure your network settings, such as Wi-Fi networks and mobile data settings. You can do this by going to the respective sections in the “Settings” app:

• For Wi-Fi: Go to “Settings” > “Connections” > “Wi-Fi” and select your Wi-Fi network. Enter the password if required.
• For Mobile Data: Go to “Settings” > “Connections” > “Mobile networks” and configure your mobile data settings.
• For Bluetooth: Go to “Settings” > “Connections” > “Bluetooth” and pair your device with other Bluetooth devices if needed.

By following these steps, you can reset the network settings on your Samsung phone and resolve network-related issues or start fresh with your network configurations.
