Unreadable text messages

It is recommended to change to a SIM card that can receive long text messages. If it still cannot be received, there is nothing you can do. Go to the Samsung repair center

The normal word count of mobile phone short messages follows the following format:

Short message length:

The length of ordinary short messages is: 160 characters for English messages and 70 Chinese characters for Chinese messages;

Supports concatenating short messages (multiple ordinary short messages form one long and short message) message), can support the concatenation of N (depending on different mobile phones, for example 5) ordinary short messages. In each split short message, 6 bytes of overhead are used as headers for concatenation of short messages. Therefore, each message can only have (140-6) bytes as the actual content of the message. Therefore, each line can support (140-6)*8/7=153 pure English characters, (140-6)/2=67 mixed Chinese and English or pure Chinese characters. Therefore, a long text message can support up to 153*5=765 pure English characters and 67*5=335 mixed Chinese and English or pure Chinese characters.

Generally, short message capacity is not allowed to be modified. Your friend sends you a multi-page text message. The text message is first saved in the operator's short message center (smsc). If smsc determines that your phone is on, it will be sent. Here you go. Each page has a serial number, indicating the serial number of this short message. When the short messages arrive on your phone, your Samsung phone starts to form a long text message and reminds you that a new text message has arrived.

According to your statement, if you cannot receive it, it cannot be a problem with SMSC, or it cannot be that your mobile phone did not receive the short message sent by SMSC. I guess this phone does not support the function of concatenating short messages (that is, combining multiple short messages into one long short message), so when a new short message comes, your phone will not really notify you.
