So when you first found out about this problem, call 10086 first to see if it indicates that there is no phone bill. Another more common is the SIM card problem, there are many kinds of this problem, sometimes there is a problem with the sim, he will prompt "SIM card not detected".

Sometimes it doesn't prompt you, you just can't dial **, and often you can't dial 10086. At this point, you can remove the SIM card and reinstall it. Sometimes the problem is solved.

But sometimes if it doesn't work to reinstall the SIM card, maybe your SIM card is broken. You can go to the business hall and get a new SIM card.

The last case is that your phone's hardware is faulty, and it is best to find a professional repair point for repair.

Summary. What happens when a credit card expires and the card fails to be replaced There are 3 main reasons for this: 1The credit card is not activated.

If the credit card is not activated within the validity period, it does not meet the bank's conditions for renewing the card, and the bank will not replace the cardholder with a new card. At this time, the cardholder needs to apply for a new credit card and wait for the new card to be activated before it can be used normally. 2.Credit card overdue.

When the overdue is serious, the credit card will be frozen or blocked, and the credit card is overdue, why does the bank give you a new card? Credit cards in this state are also not eligible for a new card. Generally, credit cards that are overdue for more than 3 months, the amount of arrears is relatively large, and the probability of being blocked and frozen is relatively large, so it is best to be overdue.
