Description

Technical field

[0001] The invention belongs to the field of communication technology, and in particular relates to a method, a device and a communication terminal for clearing contact information. Background technique

[0002] At present, when calling a contact stored in the SIM card or communication terminal, if the contact changes the phone number, the communication terminal will prompt the user "The number you dialed has expired" and "The number you dialed is empty" and many more. When the call ends, the information of the called contact including the phone number is still stored in the SIM card / or communication terminal.

[0003] However, an ordinary SIM card can only store about 250 contact information, and the communication terminal can generally only store 1000 or more contact information. Regarding the storage method of the SIM card, the capacity of the SIM card is very likely to be full; In addition, some phone numbers that are not frequently contacted may be shut down ...
