I cannot send text (SMS) messages
* Please note, this section is designed to give you basic product troubleshooting information, also refer to your user manual for more information.
There are two scenarios for this issue:
■ Unable to send text messages to a specific contact, but can send messages to other contacts
If there is only one contact to whom you're unable to send any text messages, the problem very likely lies with the network and not with your device. Please contact your network operator to see if they know of a solution. If possible, it is also worth asking your contact to ask his or her network operator about the problem, too.
■ Unable to send text messages to any of the contacts
If you're unable to send any SMS (text) messages to any contacts, but your phone is perfectly functional, try checking your network operator's message centre number stored in your device's settings. It is either missing or incorrect. Follow the steps below to check.
Note: Steps shown below are based on Android version 4.2.2 (Android Jellybean software)
Check the Message Centre number:
Step 1: From the Home screen, tap Messaging.
Step 2: Tap the Menu key. Then, tap Settings.
Step 3: Locate Message centre. Directly beneath it should be the message centre phone number of your network operator. (Check your network operator's website for their message centre number to compare). If the number on your phone is different, or missing, touch Message centre, enter your network operator's message centre number and then touch OK. Then try sending a text message.
If the text message still won't send, or if your phone already had the correct message centre number stored, please proceed to the next steps to clear the data in the Messaging app.
Note: For Marshmallow OS devices, follow these steps: Open Messages App > MORE > Settings > More Settings > Text messages > Message Centre > Set message center and tap SET
Clear the Messaging app's data:
Step 1: From the Home screen, tap Apps.
Step 2: Tap Settings (you may need to swipe left or right to locate it first).
Step 3: Tap Application Manager (you may need to tap the More tab first).
Step 4: Swipe left several times to see the All list of apps. Scroll down to locate Messaging and tap it.
Step 5: Tap Clear Data. Then, tap OK on prompt.
Step 6: Restart your device.
Step 7: Try sending a text message. If it doesn't work, perform a factory reset on your device. Follow the steps below.
Perform a factory reset
Step 1: Back up all the media, text messages, etc. that you wish to save. This can be done through Kies on your PC. A factory reset will wipe your phone clean, restoring the software to how it was when the device left the factory.
Step 2: From the Home screen, tap Settings.
Step 3: Go to Accounts tab. Tap Back up and reset.
Step 4: Tap Factory data reset.
Step 5: Tap Reset device.
If you're still unable to send any text messages after setting up your device again we recommend arranging for a Samsung engineer/technician to inspect your device.
