SimCard

[user_1029202_6]

My S21 5g cant communicate with sim card. One physical card and two esims, soft and hard resets, and a factory reset to boot and I am still not getting anything. Anybody got any good tips or advice? Thank you

If your Samsung Galaxy S21 5G cannot detect any SIM cards or eSIMs after a factory reset, the issue is likely a hardware failure—such as a damaged SIM reader, a loose internal flex cable, or a dead baseband/motherboard chip
