Is there a charge for OA mobile version access?

Don't choose free, because free is not safe. Mobile OA system is a new generation of collaborative office products based on meeting users' mobile office needs and eliminating geographical and spatial restrictions. It can enable enterprises to enjoy the convenience brought by information system while their business is developing rapidly, and can well adapt to the actual situation of rapid changes in enterprises, limited information funds and lack of professional information talents, and provide better, more convenient and more efficient management tools. At present, several powerful OA manufacturers have mobile phone OA products, but I still think Zhiyuan OA has good performance by comprehensive comparison. Zhiyuan mobile phone OA system is a set of mobile information system based on portable terminals such as notebooks and mobile phones. The system organically combines smart phone, wireless network and OA system to develop a mobile office system, which realizes seamless access to any office place and office hours and improves office efficiency.
