Why can't I receive my card number information?

Samsung mobile phone has this problem, so it is generally recommended to follow the following steps for troubleshooting and handling:

1. Check whether you can make a phone call, and rule out whether the phone bill is insufficient or the network signal is unstable.

2. If the call is normal, please check whether the SMS blacklist function is set.

3. Check whether the information center number is entered correctly (hint: the telecom card has no information center number setting).

4. Try to replace another SIM card.

5. If it is invalid, please back up the information (contacts, pictures, etc.). ) and restore the phone to the factory settings.

If the problem still exists, I suggest you take the purchase invoice and replacement card and send your mobile phone to the nearest service center for testing.

The address information/customer service telephone number of Samsung Service Center can be inquired in the following ways: Please log in to Samsung official website-click on the after-sales service in the upper right corner-click on the search Samsung Service Center-select the product you want to inquire and the province and city where you are located to search.

Tip: If there is no service center in your city, please contact the after-sales service centers in neighboring cities first and ask if you can check and repair by mail or express delivery.
