Why does Apple's mobile phone secondary card still take traffic when it turns off traffic?

by Poster Mar 6, 2025 22
Apple 15 pro, main card telecom, secondary card mobile 9 yuan number guarantee package, if traffic is used 2 yuan/day/G. For the telecom selection of cellular data, "Allow to switch cellular data" is turned off, and the traffic is still used occasionally for a month. Basically, there are few months to pay 9 yuan. Is it Apple's problem or the operator's problem?

    My giffgaff card is placed in an old iPhone that is not in use. In order to prevent traffic loss, I directly turned off the cellular data completely. As a result, every month, the bill sent to my email will have a little traffic. I don't know whether this amount of traffic can meet the needs of guaranteeing the number. To be on the safe side, I'd better send a separate text message to guarantee the number.

    @ Anonymous7255 @ Anonymous8388 @ Anonymous457 @ Anonymous5473 Thanks for the pointers. I'll verify it in the past two days! The number must be guaranteed this month, and the call can be transferred to another data card.
