The mobile phone keeps prompting that the SIM card information is full!

1. The SMS set by the mobile phone is stored in the SIM card, which causes the SIM card to be full.

Solution: Find the function of deleting short messages and delete all short messages at once.

2. The phone is set to use the SIM card as the phone book, and it is full (about 200 names+phone numbers).

Solution: Find the function of backing up or copying the phone book, back up or copy the name and phone number stored on the SIM card to the memory of the mobile phone at one time, and then delete the phone book stored on the SIM card at one time.

3. If the SIM card chip fails, and the memory is still full after handling according to the above situation, the SIM card chip fails, resulting in the inability to obtain the memory space correctly.

Solution: In this case, you can go to the operator to apply for a new SIM card.

It should be noted that the storage space of SIM card is not the memory of mobile phone body, nor the memory of mobile phone SD card. Generally, there will be a capacity sign on the SIM card.
