Description

technical field [0001] The invention relates to a communication device, in particular to a communication device with a short message service controller capable of controlling additional short message service. Background technique [0002] In today's information life, it has become a common phenomenon that people use mobile phones to communicate. No matter when and where, users can contact each other by calling, sending text messages, sending letters, etc. to maintain mutual feelings or exchange relationships. message. Early mobile phones only supported a single mode. This mode can only use a single subscriber identification card, also known as a SIM card (Subscriber Identity Module). Therefore, one mobile phone only corresponds to one door number. When a user wants to use two or more numbers, he must purchase two mobile phones or more than two mobile phones to meet the requirements for using the numbers. [0003] However, with the development of the market, many telecommun...

Problems solved by technology

[0003] However, with the development of the market, many telecommunications service providers have been established one after another, and many users also have more than two phone numbers, so they need to communicate with more than two mobile phones. However, users carry two mobile phones with them. It is very inconvenient to have two or more mobile phones and cause troubles for users in use, and increase the burden of users' capital expenditures
