What to do if a smartphone was stolen without a SIM card?

Question

Mobile devices

Question: is it possible to find it if the imei code of the phone is known, provided that the thieves themselves will not insert the SIM card ??? I would like to assess the chances of finding it.

Answer 1

Go to the police and write a statement about the theft.
Take documents with you to your phone with its IMEI number.
With the same documents, write a statement to all 4 operators (BEELINE, MTS, MEGAFON, TELE2), attaching a certificate of initiation of a criminal case.
If he appears on the network, then an opera comes to the unlucky buyer, takes the phone and returns it to you.

Answer 2

The previous answer is certainly interesting, but is the game worth the candle?)
