To set up the default SIM card for calls and messages, read the detailed steps below:

  • Go to the Settings menu.
  • In the settings menu, you have to tap on the SIM management.
  • In the SIM management, you will find the two categories:
    SIM Management & Preferred SIM for mobile data, calls and messages.
  • These settings are available in all the dual SIM android phones. There may be different settings for different Android vendors but more or less the steps are the same.

In the SIM card management you have the following options to change settings:

  • Enable or disable the SIM card.
  • You can enter the SIM card number for your reference only.
