Method, device and terminal for acquiring SIM card data

The present invention relates to the field of communications, and in particular, to a method, device, and terminal for acquiring SIM (Subscriber Identity Module) card data. Background technique

After entering the 3G era, mobile operators face long-term coexistence of multiple networks such as 2G and 3G and subsequent LTE (Long Term Evolution). Many mobile operators have adopted multi-network collaboration as an operational target and optimization strategy. "Do not change cards, do not change numbers, do not need to register" three non-principles and custom multi-mode terminals for business promotion and multi-network operations.

Multimode terminals can be divided into multi-card and single-card. Multi-card multi-mode terminals use multiple SIM cards, each card corresponding to a separate communication system, which can reside in different communication systems. Single-card multi-mode uses a SIM card to reside and complete the corresponding communication functions according to certain terminal policies, network policies or business policies.

With a SIM card, multimode terminals can reside in different network modes, that is, single-card multi-mode multi-standby terminals. It not only avoids the burden of the single card user to purchase the card, but also reduces the overall power consumption of the multimode terminal.
