Modules can’t read sims. Can’t find latest firmware on website

First of all, ask your operator to confirm whether your sim card supports gsm service. In addition, check whether your mobile phone can recognize these sim cards. I will look for the new firmware and send you a private message later

You’ve got the latest version, M26FAR03A06

Hello Vincent. I have confirmed with manufacturer that it supports the SIM operator.

They told me to write these codes

It worked for my friend but not for me

AT+QSIMDET=0,0,0;&W

AT+QSIMVOL=2&W

any suggestions on this matter?

Hi ineedsupport
Are you trying to turn off sim detection? Still want to enable sim card detection, refer to the AT manual:
