Anyone experiencing a no signal/service with a 🚫 sign after doing a security update?
Phone was working perfectly. Did a security update anx all of a sudden i have no access to any mobile signal. I've tried every possible solution including a hard reset.

Have you tried going into settings, general management,  reset,  reset network connection @Rūmøur 

Also as a process of elimination can you try your sim card in another phone and then see what happens which can help to rule out network issues and or sim card issues.

When you say you've tried a " hard reset " do you mean a factory reset  ?

Oher options to try if you haven't already are....

A Samsung Experience Store  / Samsung Service Centre can take a look at your phone.

I wish you all the best with this situation.
