What is the Default SIM Card in Android Phones?
When you insert the 2 SIMs in both the slots, by default the SIM 1 will be used to make calls, send messages and utilize mobile data. So the default is SIM 1 unless you change the settings and specify the particular SIM for wireless operations.
For using the mobile data, you can only use 1 SIM at a time and you have to specify the SIM slot for the mobile data. You can also specify a different SIM card for sending messages and a different card for making calls.
All the three settings are totally different from each other and you can use individual SIM for particular work. Some of the Android phones have the facility to take permission to select the SIM slot from the user before placing a call.

We already know that you have to manually select the SIM slot for making calls, sending messages and using mobile data. Many of the users select a different SIM for placing calls and using mobile data according to their carrier services.
To set up the default SIM card for calls and messages, read the detailed steps below:
- Go to the Settings menu.

- In the SIM management, you will find the two categories:
SIM Management & Preferred SIM for mobile data, calls and messages.

In the SIM card management you have the following options to change settings:
- Enable or disable the SIM card.
