EC-25-J Band41 Disable

IoT Modules LTE Standard Module
1

Hello,

I am using an EC25-J module with a KDDI SIM, and I need to disable Band 41.

I have attempted to disable it using AT commands, but I have not been able to achieve this.

According to various forums, it may be necessary to update the firmware of the EC25-J to upport this functionality.

My current firmware version is:

EC25JFAR06A06M4G

Could you please provide a firmware version that allows Band 41 to be disabled?

Best regards,

hi there,
Have you try to lock the band using the command AT+QCFG=“band” ?

Thank you for the information. I have tried the AT commands provided; however, it seems that the firmware enforces a lock, preventing me from disabling BAND41. I would appreciate any suggestions or possible workarounds.
