Check Network Coverage

4. Go to Settings > Connections > Mobile networks and ensure “Network mode” is set to “5G/4G/3G/2G (auto connect)”.

Ensure Call Forwarding is Disabled

Call forwarding might be redirecting your calls elsewhere. To check and disable it:

3. If it’s highlighted, tap it to turn off Do Not Disturb mode.
4. Alternatively, go to Settings > Notifications > Do not disturb to adjust settings.

Ensure Call Blocking is Not Enabled

Accidentally blocking contacts can prevent their calls from coming through. Here’s how to check:

1. Open your Phone app.
2. Tap the three-dot menu and select “Settings”.

2. Tap “Reset settings” to confirm.
3. Enter your PIN or password if prompted.
4. Restart your phone after the reset is complete.

Try a Different SIM Card

Using a different SIM card can help determine if the issue is with your current SIM or the phone itself. Follow these steps:

1. Power off your phone and remove your current SIM card.
2. Insert a different SIM card (ensure it’s compatible with your carrier).
3. Power on your phone and wait for it to connect to the network.
4. Try making and receiving calls with the new SIM.

Contact Your Carrier for Assistance

If none of the above solutions work, your carrier’s support team can provide further assistance. Here’s what to do:
