Is there any difference between the main SIM card and the secondary SIM card in the POCO X7 Pro?
The POCO X7 Pro doesn’t distinguish the main SIM card and the secondary SIM card.
For your reference, here is more information about the main and secondary SIM cards distinction:
1. The main and secondary SIM cards in dual SIM smartphones refer to two different mobile network connections in the same phone. These SIM cards can be used for voice calls, text messages, and mobile data;
2. Main SIM is the default card for calls, messages, and mobile data unless you change it. Secondary SIM provides flexibility and can be used for additional calls, text messages, or data functions. You can switch as needed;
3. If the phone does not support the main and secondary SIM card distinction, it means the phone cannot automatically or easily assign certain default functions (like mobile data, voice calls, or SMS) to a specific SIM card. In such cases, both SIM cards are treated equally without a clear distinction of a "primary" and "secondary" card.
