Dual-SIM Problem

    ekongd , Feb 26, 2020 :
    I have a new One Plus 7T phone.
    In SIM1: Visible
    In SIM2: Red Pocket (AT&T).
    Voice, SMS, and data are all set to SIM1 (Visible).

    This is my problem:

    When I startup/restart my phone, the Red Pocket (in SIM2) is the first SIM that is up and running, the phone automatically sets the data to SIM2.

    By the time the Visible (in SIM1) is ready, only voice and SMS are assigned to SIM1 (Visible). I always have to reassign data to Visible (SIM1).

    I did not have this problem with a Pixel 3a (Visible-SIM1, and AT&T prepaid eSIM).
