Network Issues

One of the primary reasons for text message failures is network-related problems. It could be due to weak or no network coverage in your current location. Try changing your network mode from 5G/4G to 4G/3G and relocating to a different area. By doing so, you can check if your signal strength improves and potentially resolves the problem.

1. Head into your Settings > Connections.

2. Select Mobile networks > Network mode.

3. Then downgrade your network mode.

Incorrect Message Centre Number

Each mobile operator has a unique message centre number that handles the routing of text messages. If this number is not correctly set up on your phone, it can cause issues sending and receiving messages. Verify the correct message centre number with your mobile provider and update it within your phone settings.

Please Note: You will need to reach out to your network provider to obtain the correct Message Centre number.

1. Launch the Phone Message app.

2. Tap on menu > Settings.

3. Select More Settings > Text Messages.

4. Then tap on Message Centre and enter the correct Message Centre number.

SIM Card Issues

A faulty or improperly inserted SIM card can also lead to text message failures. Make sure your SIM card is properly placed within the SIM tray and that it is not damaged. Try removing the SIM card, cleaning it, and reinserting the SIM back into your Galaxy device.

Please Note: You will need to reach out to your network provider if the SIM card is damaged or faulty.

Outdated Software
