Xperia L  Mobile data  Stops working after a  day.   Recent Update done was  15.3.A.0.26.

I have done a factory reset.   Downloaded the Internet setting.  

The mobile data works only after restarting the phone.  and Works for 5-10 hours.    Then stops working.

Reenabling the mobile data after this does not work.

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

I suggest that you try using another SIM card and check if you still experience these drops.

If yes, I suggest that you try to reinstall the phone software using Update Service..

Before reinstalling your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?

Before doing the upgrade i was using the same phone and same connections. No changes.

Also i have tried the update service  using PC Companion.
