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?
