Software Issue For Samsung Galaxy A40s

[nitni]

Hello,

I have 2 Phones, they both are Samsung Galaxy A40 model.

Since a week ago, I've been experiencing this weird issue in both phones (Galaxy A40), whenever I send a SMS it says Error "Couldn't send message".

This has never happened before, its not the Network because I checked, it is a recent software issue and it has happened.

-Since a week ago

-To both Phones that happen to be the same Model.

So, the Error is that SMS messages says "Couldn't send message" and it's been happening to both phones, same model Samsung Galaxy A40.

Its not the Network

Its not the Contact because I have been tried to send SMS to diff contacts

Its not balance because I have enough

Its not network

Both Phones Samsung Galaxy A40 give me the Error "Couldnt send message"

Please help

Hi @nitni  Welcome to the Samsung Community

Firstly check that Mobile Data is enabled. check that your preferred sim is assigned to Messages, Settings-Connections-Sim card Manager. check that Text is set as Default if that is preferred option, Settings - Chat Settings -Select Default Messaging Type, and set this to 'Text or Multimedia Messages'. If you go to Messages- Menu(3 dots)-Settings-More Settings-Text Messages check that a number is poulated in the Message Centre Section. If not you would need to contact your Network.

otherwise restart phone and check for any updates. you may need to clear the Messages cache,Settings-Apps-Messages-Storage-clear cache. If no solution try resetting the Network connections,Settings-General Management-Reset-Reset Network Settings. you may need to reinsert sim to see if that makes a difference ot try in another phone if possible.  You would still need to contact provider if troubleshooting fails.
