检查sim卡网络服务是否可用 [英] Check if a sim card Network service is available or not

问题描述

我正在开发一个根据SIM卡状态更改按钮的应用程序

Hi I am developing an application that changes a button according to the SIM STATE

我为无SIM卡使用1，为SIM卡就绪使用5

I am using 1 for NO SIM and 5 for SIM READY

例如，在极少数情况下，我不提供服务，如果SIM卡是国际卡，则在其他地方无法使用.这种情况的SIM状态是什么.

In few case I have no service for example, if the SIM card is an international card , It doesn't work in other places. What is the SIM State for this type of condition.

请提出如何检查是否有SIM卡但没有服务的信息.谢谢！

Please suggest how to check when there is a SIM card but no service. Thanks!
