PHP send at command, PHPAT instruction

Need: Send text message to user input phone, request can customize information content

Problem: No telecom cat, no custom SMS content with free API interface

Solution: Through the 4G network card, connected to the server, through the AT command to operate the network card, send SMS

Lookup found that the at quality send requires multiple encoding of the information, and the send timed out, but the actual delivery is successful, the problem is not fully resolved

The code is as follows:
