M6 pro MR6550 5g not working in South Korea
Hello, everyone
I recently bought an unlocked MR6550 from Amazon.
When I connected to the mobile Internet with a SIM, only 4G is connected, and 5G is not connected.
I am currently using the MR6550 in South Korea. The carrier is SK Telecom.
Could you please let me know how i can solve this issue.
The SKU and firmware of the MR6550 are as follows.
SKU: MR6550-100PAS
Firmware: NTGX65_12.01.20.00
When i tried to update firmware, it's already the latest version, so the update dosen't proceed anymore.
How can i download the latest version of firmware? and can i install the firmware manually?
Thanks

JKYooDid you solve the problem?
To enable 5G connectivity, SKTelecom requires device registration. (5G-OMD)
All three cellular carriers use N78 for their 5G services.
SKTelecom
LTE: B1, B3, B5, B7
5G: N78
Korea Telecom
LTE: B1, B3, B8
5G: N78
LG U+
LTE: B1, B5, B7
5G: N78
I want to use MR6550 in Korea, but I want to be sure 5G can be enabled before buy it.
