短信群发系统，在一些业务范围广泛的公司中，当公司有了新的通知要告诉在外地的员工，通常使用拨打电话的方式，这样虽然能把事情说清楚，但是当在外的员工比较多时，工作量很大，为了解决这个问题，可以开发一个企业短信群发管理系统。企业短信群发管理系统主要利用硬件短信猫发送短信，并且可以查看SIM卡中收到的短信。(Mass messaging system, in a number of business a wide range of companies, when the company has a new notification to tell the staff in the field, normally used by calling the way, so although things can make it clear, but when the staff out for a long time compared , the heavy workload, in order to resolve this problem, can develop an enterprise management system for mass text messaging. Short Message management system for enterprises mainly use the hardware to send SMS text messages a cat and can view the SIM card text messages received.)
