Sony xperia M problem

[Paul20141]

I am uisng Sony Xperia M single Sim for last 3 month.  Even though i receives  signal from Vodafone, my Xperia M goes to unreachable. No one will be alble to call me /Sent SMS and even I can't make outgoing calls. 

Once the Phone rebooted issues gets solved and again repeats the next day.

Every time some one says I was unreachable from yesterday evening.

How to rectify the issue, is it related to any hardware issue.

Please suggest

Thanks

Paul

You could check your SIM in another device,see if it works.

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

You can also try with another or new SIM card in your phone. 

If you experience the same behavior with another SIM, I would suggest that you try to boot your phone into safe mode to see if the problem may be related to any 3rd party app that you have installed in your phone:
