Apple 1 1pro dual card secondary card traffic can turn off the main card?

Apple 1 1pro dual-card secondary card can't be used after the main card is turned off. Because when the secondary card is closed or turned off, the traffic in the card will also stop. Therefore, even if your primary card has residual traffic, the secondary card cannot use the traffic.

If you need to continue to use the traffic on the secondary card, it is recommended that you turn on the "dual card traffic * * *" function. When this function is turned on, you can share the traffic in the primary card with the secondary card. Even if the main card is turned off or there is no signal, the secondary card can continue to use the traffic in the main card.

To turn on the "Dual Card Traffic * * *" function, you can follow the following steps:

1. Open the phone settings and enter the "Cellular Mobile Network" option.

2. Select "Traffic Master Card" and turn on the "Traffic * * * Enjoy" option.

3. In the "Traffic * * * Enjoy" option, select "Dual Card * * * Enjoy".

4. After "Dual Card Sharing" is turned on, you can choose to share the traffic in the main card with the secondary card, or let the secondary card use a separate traffic package.

It should be noted that turning on the "dual card * * *" function may increase the traffic consumption in the main card. Therefore, when using this function, it is recommended that you plan the traffic usage reasonably to avoid generating additional traffic charges.
