HOW TO CHECK CARRIER AGGREGATION SUPPORT ON YOUR S9/S9+

From dialer dial : *#0011# OR *#2263#

you will enter the service mode

You will be able to see STACK 1 , 2 and for few users 3.

Open the stack 1 / 2 and check under CA , if its NONE then aggregation is not yet supported in your area.

This happens automatically and is carrier driven .
