Your post was blank @carlocaroline so the precise nature of your problem isn't clear.
If you want assistance from the Community Forum then you need to explain your issue clearly and in detail.
Are calls and texts working ok for you?
When was mobile data working ok for you last?
Are your APN settings (still?) configured correctly?
Any other relevant information that might help others to understand your issue better?
