2. Check Your Signal Bars

No signal means no calls. Even if it shows some bars, the connection might still be unstable.

1. Look at the top of your screen to see your signal bars.
2. If you have no signal or a weak one, move to another spot — near a window or outside.
3. If available, turn on Wi-Fi Calling in Settings > Connections > Wi-Fi Calling.

3. Make Sure Airplane Mode Is Off

Airplane Mode blocks all calls. It’s easy to turn on by mistake.

1. Swipe down from the top of your screen to open Quick Settings.
2. If Airplane Mode is turned on (the airplane icon is lit), tap it to turn it off.
3. Wait a few seconds for your phone to reconnect to the network.

4. Reinsert the SIM Card

A loose SIM card might stop your phone from connecting to your mobile network.

1. Power off your phone.
2. Use a SIM ejector tool (or a small paperclip) to remove the SIM tray.
3. Take out the SIM card, gently wipe it with a clean cloth, and place it back.
4. Reinsert the tray and turn the phone back on.

5. Check for Blocked Numbers and Call Settings

Sometimes calls fail because the number is blocked or special settings are active.

1. Open the Phone app.
2. Tap the three dots at the top right > Settings.
3. Tap Block numbers and make sure the contact isn’t blocked.
4. Tap Supplementary services or Call settings, and disable anything like Call Barring or Call Forwarding.

6. Turn Off Do Not Disturb

If you’re not getting calls, this mode could be stopping them.

2. If it’s on, switch it Off.

2. If an update is available, install it and restart your phone.

If the problem is with your mobile network settings, a reset can fix it — and don’t worry, this won’t delete your photos or apps.

2. Tap Reset mobile network settings.
3. Confirm, and then restart your phone.
4. Your phone will reconnect to the mobile network with default settings.

9. Try Your SIM in Another Phone

This helps you figure out whether the issue is with your phone or your SIM card.

1. Power off your Galaxy A16 and another phone.
2. Put your SIM into the other phone and turn it on.
3. Try making or receiving a call.
4. If it works on the other phone, the issue is with your A16 — not the SIM.

10. Contact Your Carrier

If you’ve tried everything and calls still don’t work, your account may have a billing or service issue.

1. Use another phone to call your service provider.
2. Ask if there are outages, restrictions, or unpaid balances affecting your line.
3. Ask for a new SIM card if yours seems faulty.

Getting your Galaxy A16 working again might be as easy as restarting it or turning off Airplane Mode. If none of the basics work, resetting mobile network settings or calling your carrier is your best bet.
