SOLUTION

Restart OnCell

The OnCell does not support the SIM card switch over by eject SIM card out. The SIM card will perform the “switch over” check before the cellular connection is established. Once connection is established the same SIM card is always used.

The only way is to restart OnCell to switch to SIM2.
