How to put two cards after the US version of Samsung changed its dual card?

If your Samsung mobile phone already supports dual-card function, you can insert two SIM cards according to the following steps:

1. Turn off the phone and take out the SIM card holder on the side of the phone.

2. Gently open the SIM card tray with your nails or something thin and hard.

3. Put the first SIM card into the SIM 1 slot of the tray, taking care not to damage the metal contacts.

4. Put the second SIM card into the SIM2 slot of the tray, taking care not to damage the metal contacts.

5. Carefully insert the SIM card holder back into the phone, and make sure that it is inserted and the card slot is locked.

After the insertion is completed, turn on the phone and set it. Please note that different Samsung mobile phone models in the United States may have slightly different card insertion methods. Please read the instructions carefully or consult the official customer service.
