Why is there no SMS notification?

I don't know what your SMS notification means. This may be due to the following reasons:

1

When you received the text message, it didn't pop up on your mobile phone in time to inform you. This is because you turned off the SMS notification function. You can set this SMS notification function to on in the settings.

2

You can't receive the check code. This may be because you set the anti-harassment SMS function on your mobile phone. You can cancel this function in Settings or Phone Manager.

three

Your cell phone signal is not good or you owe money. Just try to change places or pay the phone bill.
