Failed to register the card.

1. Check whether the SIM card account is in arrears. If yes, top up the account.
2. Check whether the network quality is poor. If yes, use a SIM card of another carrier with good signal quality.
3. Check whether the SIM card has been bound to another device. If yes, unbind the SIM card from the device or replace the SIM card.
