The goal back then was to free a SIM card from an always-plugged-in old phone, so that it could make and receive calls through Asterisk and forward SMS through Telegram and similar tools. A few years later, I saw a seller clearing out first-generation DJI Enhanced Transmission modules on Pinduoduo, so I bought one for a little over 30 RMB. Its USB ID shows up as <code>2ca3:4006 DJI Technology Co., Ltd. Baiwang</code>, but based on online information and its AT command responses, it is essentially an EG25/EC25-class Qualcomm-based modem. The catch is that it cannot be flashed with standard Quectel firmware.</p>
