I cannot send text (SMS) messages

Last Update date : 2017.11.10



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 you're unable to send any text messages to, the problem very likely your

network provider and not your device. Please contact your network operator for service status updates.



Unable to send text messages to any of the contacts


If you're unable to send any SMS (text) messages to any contacts, try checking your network operator's

message centre number stored in your device's settings. It is either missing or incorrect.



Check the Message Centre number:


Step 1: From the Home screen, tap Messaging.



Step 2: Tap the Galaxy Menu Key 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, tap 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.
