Firmware EC25-ECRequest for Latest EC25-EC Firmware – SMS Not Working on LG U+ (Korea)

Hello,

I’m currently working on a project using the Quectel EC25-EC module.
The firmware version on my device is:

EC25ECGAR66A02M1G

I am testing in South Korea using the LG U+ network, but SMS sending is not working.
I’m not sure if this is related to IMS registration or a firmware issue.

I’ve read that updating to the latest firmware may resolve this problem.
Could you please provide the latest firmware version for EC25-EC, along with any necessary tools or instructions for the update?

Thank you for your support!

Best regards,
Jin Kim
