I activated a prepaid SIM on international version Samsung Galaxy Note 9 (SM-N960F/DS), and while I can access LTE networks, it doesn't seem to use carrier aggregation. The device can connect to all the bands it supports (2,4,12), but not at the same time? When I activated this device on other country (South Korea) I could use LTE-A with no problem, despite the device being bought in Thailand. Is there any way to fix this?
