Hi @-Илюха-, sorry to hear about this.

I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.

I would recommend that you try with a different SIM card in the device. That way we can see if your SIM card is defect or if the unexpected behaviour is related to the SIM card reader in the device. You can order a new SIM card if you contact your operator.

Let me know how it goes!
