Normal reasons for the downtime of the main card and the secondary cardIn modern life, mobile phones have become an indispensable part of us. However, sometimes we may encounter a situation where the primary card is working normally, but the secondary card suddenly stops. What's going on here?This topic describes the possible causes of normal secondary card shutdown and provides solutions.
First of all, we need to understand that when the mobile phone is in arrears or overdue payment, the mobile operator will stop the supplementary card first. This is to prevent customers from getting an SMS reminder and getting a new card without paying the fee. Therefore, if this happens to your mobile phone, it is recommended that you pay the fee as soon as possible so as not to affect the normal use of the supplementary card.
Secondly, there may be a problem with the card slot where the secondary card is located. Sometimes, due to prolonged use or improper operation, the card slot may malfunction. In this case, you can try to troubleshoot by inserting the secondary card into another card slot. If the supplementary card still does not work properly after replacing the card slot, we recommend that you contact the carrier's customer service for assistance.
In addition, the supplementary card may need to be activated or adjusted to the network settings. If you've just purchased a new supplementary card, or have changed to a new phone, the additional card may need to be activated. At the same time, you will also need to adjust the network settings of the supplementary card to ensure that it can be used properly. In this case, it is recommended that you contact your carrier's customer service for assistance.
Finally, the supplementary card may not support the network standard currently in use. The network standard supported by different mobile phones and supplementary SIM cards may be different. If your phone uses a specific network standard and the supplementary SIM does not support this standard, the additional SIM card will not work properly. In this case, you need to replace the additional card that supports the corresponding network standard.
In short, there are many reasons for the normal downtime of the primary card, which may be caused by arrears of the mobile phone, faulty card slots, activation or network setting problems, and unsupported network standards. In this case, it is recommended that you first check whether your phone is in arrears or overdue payments, and then try to change the card slot or contact your carrier's customer service for help. At the same time, you need to make sure that the supplementary card supports the network standard you are currently using. Hopefully, this article can help you solve the problem of normal secondary card shutdown of the primary card, so that your mobile phone can be used more smoothly.
