as ASC functions. Here is an example of each of the two functions:? ASCW ("short ")30701? Chrw (26482)Bytes
We can see that these two functions can convert Chinese and Unicode codes, which is very convenient for encoding and decoding. After we get the Chinese Unicode code, we can compile the PDU string.
Let's take a look at the composition of the PDU string. We can see this PDU string (used when I debug the program): quit. We break it down:

The user did not write the local number into the SIM card.
Once you write your local phone number into your SIM card, you can use at + cnum to find the number of your mobile phone number.
Action command returns the msisdns related to the subscriber (this information can be stored in the sim or in
Me). If subscriber has different msisdn for different services, each msisdn is returned in a separate line.

, a maximum of 70 characters can be sent, whether in English or Chinese.For example, we want to send the following message to my mobile phone 13715342642. "Hello, Hello! ". Before sending the email, you must be clear that the SMS center number in the SIM card's location is not the SMS center number in your current location. For example, if I am in Shenzhen, the SMS center number in Shenzhen is 8613800755000, even if I am outside China, the SMS center number is still in Shenzhen. We get the follo
