Description

Technical Field

[0001] The invention relates to the technical field of wireless data networks or service support terminals, and in particular to an intelligent card selection method for multi-SIM card equipment. Background Art

[0002] At present, the number of SIM cards in existing wireless terminal devices is limited, and the number of SIM cards is mostly 1 to 2, and it is impossible to support the insertion and use of more than 2 SIM cards. In addition, there are four types of SIM cards in China, namely China Mobile, China Unicom, China Telecom, and China Broadcasting Corporation. The traditional SIM card switching operation requires customers to select by themselves, and at most only two SIM cards can be selected at a time. After the selection, only the selected SIM card can be used for subsequent services. If other SIM cards are used, it is necessary to frequently remove and insert the card for card replacement.

[0003] In addition, customers cannot judge whether the currently selected SIM card can obtain the best service in the current environment. For example, the customer selects a China Unicom card, but the China Unicom network cannot meet the customer's service needs in the current environment. On the contrary, the service of the China Mobile card is sufficient. In this scenario, the traditional way of selecting a SIM card can no longer meet customer needs. Summary of the invention
