Method and system for automatically switching subscriber mode through identifying IMSI

摘要

A method for automatically switching subscriber mode through identifying IMSI includes, when a cell phone is turned on, determining if a first IMSI is consistent with a pre-stored second IMSI. If the first IMSI is determined to be consistent with the second IMSI, the cell phone enters a subscriber mode corresponding to the second IMSI. If the first IMSI is determined to not be consistent with the second IMSI, the first IMSI is matched with a third IMSI of an IMSI list pre-stored in the cell phone; when the first IMSI is determined to be consistent with the third IMSI, the cell phone enters a subscriber mode corresponding to the third IMSI. Thereby, the cell phone quickly and efficiently completes identifying an IMSI and automatically switches subscriber mode.

主权项

1. A method for automatically switching a subscriber mode through identifying an IMSI, the method comprising:
when a cell phone is turned on, reading a first IMSI of a first SIM card currently inserted into the cell phone; determining if the first IMSI is consistent with a second IMSI pre-stored in a memory of the cell phone, wherein the memory of the cell phone is separate from the first SIM card, and wherein the second IMSI was pre-stored in response to a shut down of the cell phone; if the first IMSI is determined to be consistent with the second IMSI, the cell phone enters a subscriber mode corresponding to the second IMSI; if the first IMSI is determined to not be consistent with the second IMSI, the first IMSI is compared with a third IMSI in an IMSI list pre-stored in the cell phone; and when the first IMSI is determined to be consistent with the third IMSI, the cell phone enters a subscriber mode corresponding to the third IMSI.
