Does anyone know why the authentication number comes too late when I get SMS certification?

I get SMS certification, but sometimes the certification number comes too late.

The phone works well, but sometimes I get text messages late...

Does anyone know the reason?

If you are in an area where cell phone transmission is not good, the carrier stores the sms and sends it when communication is possible.
There is a possibility that it is in an area where the radio waves are not easily reached.
Each carrier has different reception, so check with another person using the same carrier.

If you are sure that you receive a text message with sms authentication as a tip, it will come quickly if you are calling.
