You'll need to post a bit more information than that if you want assistance from the Community Forum.
When were you last able to successfully send texts?
What happens when you try to send one?
Any error messages?
Do texts sent to all numbers fail or just some?
Can you receive texts?
Can you make/receive calls and use mobile data?
Is your SMSC number configured correctly?
If you need to contact 48 support about this then see the links in my signature below.
