Suddenly SIM stop working

[hifumi]

So today suddenly my sim card stopped working. My phone isn't on aeroplane mode or anything like that. It has been 14 days since I bought this device also. I have tried rebooting the phone as well has factory reset, but nothing is helping. Does someone had/have a similar problem pls share me a fix to this issuse.

You need to carry just the invoice received from Flipkart. Ensure that your phone serial number or IMEI number is mentioned there. Other than this the phone and the sim card which you have been using in it.
Wish you all the best for the process ahead.

Hi hifumi,
As per what Reaperzwolf shared those details are enough. Have you tried changing or swapping different SIM?
Run SMMI test to check for possible hardware issue:
How to Enter SMMI_TEST (test hardware)
Go to Calculator=>type " .12345+= "
you will be entered to SMMI_TEST
Do also have a check if your phone's software is updated.
