Airplane mode is activated on your phone without your knowledge.
The phone's SIM card is damaged, so your phone cannot detect it.

Ways to Fix Android Samsung SIM Card Error
1. Remove and Clean the SIM card before Reinserting
During phone usage, the situation where Android, Samsung does not recognize the SIM card may arise from incorrectly inserting the SIM card. To fix this, carefully check by removing and reinserting the SIM card, ensuring it's placed correctly.
Also, check the SIM card tray for any dirt or damage. If there's excessive dirt, clean the SIM tray to ensure proper connection.
2. Move to an Area with Network Signal from Your Network Provider
Sometimes, being in areas with weak or no signal, such as elevators, basements, or remote areas, results in no signal, which is entirely normal. To address this issue, simply move to a spacious area with a signal from your network provider, and you'll get signal immediately.
3. Check if Your Phone is in Airplane Mode
Sometimes, you might unintentionally enable airplane mode without noticing. When your phone is in airplane mode, it defaults to having no signal. To turn off airplane mode, swipe down the screen from the top and tap once on the airplane icon; if the icon turns off, you have signal.
