Why does it take so long to receive a text message?

When the network signal is not very good;

There are too many users sending short messages in the same time period, and the gateway is busy, resulting in tunnel congestion;

Caused by the interconnection of different networks;

This phenomenon can also occur when the mobile phone receives a weak signal.

However, if you and your friends use the same network in the same place, others receive it normally, and yours is not normal, then it doesn't matter if you try to change your card and mobile phone to see if you receive SMS normally. If the mobile phone problem is ruled out, everything else is a network problem. You can call the operator to reflect the specific situation.

It is normal to have this kind of problem occasionally, but it is not normal to have it frequently.
