Hi Folks
I've purchased a new modem here in Australia due to the 2G network being shutdown. I had been using $15 specials that were used with Arduinos however they were 2G only. I've looked around for a 4G modem and they seem to be a little expensive hence I've purchased a 3G modem instead and have had considerable success with it.
From Aliexpress:
Factory SIMCOM WCDMA 3g SIM5216E modem Gsm USB RS232 Modem Wavecom GSM GPRS Modem By Antecheng
This unit has both a serial and USB port. When using via USB it loads in 3 drivers ie: NMEA, AT and diagnostic. It creates 3 serial ports and of course you connect to the "AT" serial port. Default speed is 9600baud.
Only initial issue I had was that it wasnt logging onto the cellular network due to poor signal strength, the plugin restarted itself when I tried to send out a message. After a little debugging ie: using AT command set I found it wasnt registered so moving the antenna, the red light on the modem began to blink...
I've had it running for 24 hours via USB and its fine. A week of testing will confirm that its all good....
Good luck to the adventurous !!
