Hello Quectel Support Team,
I am currently working with the Quectel EC25-E module, and I am experiencing a network registration issue in South Korea (LG U+ network).
Here are the details of my device:
• Module: EC25-E
• Firmware Version: EC25EFAR06A21M4G
• Issue: LTE network registration fails — CEREG: 0,2, CGATT: 0
• Signal is strong: LTE Band 5 confirmed
I suspect this issue may be related to IMS/network configuration or an outdated firmware that does not support Korea carrier profiles.
Could you please provide:
- The latest firmware package applicable for EC25-E in Korea
Thank you for your kind support.
I look forward to your guidance.
Best regards,
Junghoon Kim
