The Huawei E173 is a classic USB modem from the early 2010s, supporting 3G (UMTS) and 2G (GSM/GPRS/EDGE) networks. Like most modems from that era, it was often sold "branded" or "locked" to a specific mobile network operator (e.g., Megafon in Russia, Celcom in Malaysia). This meant you could only use a SIM card from that specific carrier. Do not unplug the modem or shut down

This firmware revision seems to optimize the power management better than the earlier B416 or B418 builds. In a 3-hour continuous usage test, the connection remained stable without the modem getting excessively hot.

This build native-enables the data/voice multiplexing required for voice-calling over 3G networks. This makes it a crucial upgrade for deployment in Asterisk telephony systems utilizing modules like chan_dongle .
