Mobile banking consists of mobile phone, GSM short message center and banking system. During the operation of mobile banking, after the user sends an instruction to the bank through the menu on the SIM card, the SIM card generates a short message with a specified format according to the user's instruction and encrypts it, and then instructs the mobile phone to send a short message to the GSM network. After receiving the short message, the GSM short message system sends it to the corresponding banking system according to the corresponding application or address. The bank preprocesses the short message and then converts the instruction into the host system format. The bank host processes the user's request and returns the result to the bank interface system, which converts the processed result into short message format.

Mobile banking is not telephone banking. Telephone banking is ICBC's voice-based mobile banking service, which is based on SMS. All the business conducted by telephone banking can be realized through mobile banking, and mobile banking can also complete the second transaction that telephone banking can't realize. For example, banks can pay telephone, water, electricity and other fees on behalf of users, but generally they can only transfer money after the user confirms it. Because mobile banking uses SMS, users can receive the information sent by the bank at any time when they turn on their mobile phones, so they can confirm the transfer anytime and anywhere.
