Question about Samsung Galaxy Note8 EU

I have Salt and Telekom in parallel in mine. The first 5 telecom cards always broke down, after a complaint I received a "special" telecom card ... since then both have been running.

The smartphone must be used with a European SIM card for at least 5 minutes of calls to permanently deactivate the region lock. After that, the smartphone can be used with SIM cards worldwide.
