Why does my Huawei mobile phone become a short message on the Internet, and the time is so long?

Please check whether the cell phone/tablet signal is good. Poor signal, network congestion or shielding equipment around may affect the normal reception of short messages.

I suggest you move to a place with a good signal and try again. At the same time, shut down security protection applications and applications with high data traffic consumption to keep the system running smoothly.
