I just bought Samsung I8552 to set up the SIM card manager. Why doesn't card 1 display the mobile phone number and card 2 displays the mobile phone number?

According to your description, I suggest you try the following methods:

1. Enter Contacts-Menu (touch the left touch button)-Display options-Click all contacts. Go back to the contact to see if the contact is displayed.

2. Insert the mobile phone card into other mobile phones to see if there are any stored contacts.

3. If you can check the contacts in the mobile phone card normally by plugging in other mobile phones, it is recommended that you back up your mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-reset-restore factory settings).

If the problem is still unresolved after returning to the factory, it is recommended that you send your mobile phone to the nearest Samsung service center for testing and further processing.

It is recommended that you apply for "booking to the store" in Samsung official website and enjoy priority maintenance service:/pre-order.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center you reserved on time.
