Fix Galaxy S25 can’t make outgoing calls

If your Galaxy S25 has signal but still can’t place outbound calls, the problem is usually tied to network registration, call settings, SIM provisioning, or a phone app glitch. Work through the fixes below in order and test a call after each method.

Method 1: Check signal, Airplane mode, and account status

1. Open Settings > Connections and make sure Airplane mode is off.
2. Look at signal bars and move to an area with stronger coverage if needed.
3. Confirm your line is active and not suspended by your carrier.
4. Restart your Galaxy S25, then place a test call.

Method 2: Verify call settings that can block outgoing calls

1. Open the Phone app, tap the three-dot menu, then open Settings.
2. Check Supplementary services (if available) and ensure outgoing call barring is disabled.
3. Review Block numbers and remove any accidentally blocked contacts.
4. If you use dual SIM/eSIM, confirm the correct line is selected as the default for calls in Settings > Connections > SIM manager.

Method 3: Reset mobile network registration

1. Go to Settings > Connections > Mobile networks.
2. Set Network operators to Select automatically.
3. Check Network mode and use your carrier-recommended mode (typically 5G/LTE/3G auto).
4. Turn Airplane mode on for 10 seconds, turn it off, and test outgoing calls again.

Method 4: Reseat or replace the SIM

1. Power off the phone and remove the SIM tray.
2. Inspect the SIM for scratches or visible damage, then reseat it firmly.
3. Power on and wait for network registration.
4. If available, test another known-good SIM or ask your carrier for a replacement SIM/eSIM reprovision.

Method 5: Clear the Phone app cache

1. Go to Settings > Apps > Phone > Storage.
2. Tap Clear cache (avoid Clear data unless instructed by support).
3. Restart the phone and try placing a call.

Method 6: Reset mobile network settings

1. Open Settings > General management > Reset.
2. Tap Reset mobile network settings (or Reset Wi-Fi and Bluetooth settings on some builds).
3. Confirm reset, reconnect as needed, then test calls.

Method 7: Test in Safe mode for third-party app conflicts

1. Press and hold the Power key, then touch and hold Power off until Safe mode appears.
2. Tap Safe mode and place a test call.
3. If calls work in Safe mode, uninstall recently added dialer, call recorder, VPN, or security apps.

When to contact your carrier or Samsung

If your Galaxy S25 still can’t make outgoing calls after all steps, contact your carrier first and ask them to:

• confirm voice service provisioning and IMS/VoLTE status,
• check for account or tower-side restrictions, and
• refresh your line registration.

If carrier checks pass, book Samsung diagnostics to rule out baseband, antenna, or SIM reader hardware issues.
