SIM Card Check: Contact the SIM card provider to verify the status of the SIM card, ruling out abnormalities such as overdue fees or lack of data usage.
SIM Card Reinsertion: After powering off, reinsert the SIM card and reconnect the device to check if the device is offline due to poor contact or incorrect insertion of the SIM card.
