Q2687 sim not allowed for this module

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.

Regards

Matt

Bad news … but Thank you.
