Q2687 sim not allowed for this module


#1

I’ve just received a Q2687 module from Amazon, and with any operator SIM I tried I always get the “SIM NOT ALLOWED FOR THIS MODULE” error.
Any AT command that interact with the SIM, like ATD, respond with error.
I also tried to update the boot loader and the firmware to the latest one, but I get the same error.

any help is welcome

Hi,

This means the unit is locked to China and Chinese SIM’s only, there is no way to change this.
