Why can't I see it by texting?

The reasons are: poor signal, system problems, being intercepted.

1, signal difference at wrong position

In tunnels, tunnels, deep mountains or sparsely populated places, the signal is generally poor, and mobile phones can't receive short messages. Or other places, but the instrument with signal shielding shields the cell phone signal, so it is temporarily unable to receive information. Just change your location and go to a place with a good signal, and you will naturally receive the information you didn't receive.

2. Mobile phone hardware/system problems

I don't think anyone wants to brush up unless they have to, but it's very simple and can be done in a few minutes. To put it bluntly, brushing the mobile phone is to reinstall the system for the mobile phone, mainly for smart phones. If the above methods do not solve the problem, you can go to the mobile phone maintenance department for repair or replacement.

3. Set blacklist and information interception.

Nowadays, smart phones are more convenient, but some spam messages often harass users, so users have to set up blacklists, but sometimes they don't pay attention. Some settings in the setting options have not been completely changed according to your own wishes, resulting in information being intercepted. You need to remove the blacklist to intercept viewing.

There are two kinds of short messages:

1.SMS: Text or digital information directly sent or received by users through mobile phones or other telecommunication terminals. The number of characters that users can receive and send short messages at a time is 160 English or numeric characters or 70 Chinese characters.

2.MMS: Its biggest feature is that it supports multimedia functions, and it can deliver comprehensive content and information, including text, images, sounds, data and other multimedia formats.
