Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

Have you tried to restart the phone? Or remove/insert the SIM-card to see if this can help? Otherwise, I suggest that you try another SIM-card to see if same behaviour appear.

yes I tried it , insert another SIM card and tried all the sim card in other phones, everything worked, I dropped the phone a few times, the SIM card phone recognizes , but the red cross indicating that no network

Are you using a MICRO SIM card or did you trimmed a regular SIM card? 

The best thing to do is to contact your local Xperia Care as this could be hardware related, since you dropped it

Hi andru_bara,

I can only suggest that you contact Sony Mobile Customer Care, as the device may require servicing. Please use the link below.
