👋 Hello everyone

👋 Hello everyone! I need help with a Samsung Galaxy A42 5G. 📱 The SIM detects the network, but cannot make or receive calls. Callers hear that the number is switched off. Credit balance and phone number are also not displayed. I changed the CSC using Global Unlocker, but unfortunately, it didn't solve the problem. Does anyone know the possible cause or have a solution? Thanks in advance! 🙏
