I knew of this constraint too, so I tested both sim cards on the tray 1 which accepts LTE, tray 2 can't. Both I also shutdown the phone, insert sim card then boot up again to test...
The tests, I make sure tray 2 is empty also. So basically both sim cards are tested on same fairness.
Quite sian actually... Maybe I monitor see how for a month of two bah. If speed is bad, then just port to other telco. It's fine since sim only right.
Just for my curiosity though. What is an average download speed (not highest or lowest) I should be expecting on Starhub sim only plan ???
