Phone suddenly not having signal

I have my phone for 5 months. Never have i encountered this problem, probably few times but a little restarting fixes it. I'm not having signal at all.. It would say "No service" when you swipe down and check the status. The status symbol is a right triangle only without any bars.Im using the same sim card for 3 years. I tried inserting my sim card on different phone and it works on that other phone(nokia asha 210). Im not able to make/receive calls or text and get mobile data, not even our local emergeny number. When trying to make an outgoing call, it says "mobile network not available". Tried every possible setting changes on Settings>Mobile Networks. Chose different APN and network type. Deleted APN and recreating manually. Went to safe mode and ultra stamina mode, just to see if an app is doing this still no. Finally i master resetted the phone. Still not working.


Just to confirm if its really the phone, i inserted my friend's sim card on mine. The same problem.


My best guess is that its a hardware problem or i should try buying a new sim card.

Repair the phone with Sony PC Companion and see if you encounter the same problem.
