a)访问SIM卡形态1：SIM卡放置蓝牙盒子内，App通过蓝牙连接蓝牙盒子，实现App对SIM卡的控制和数据交互。
b)访问SIM卡形态2：SIM卡上贴装贴膜SIM卡(不带蓝牙模块)，贴膜SIM卡可以对SIM卡进行控制和数据交互；App对贴膜SIM卡进行写电话本、写短信等操作，贴膜SIM卡接收约定的指令，对SIM卡进行操作；通过该方式，App实现了对SIM卡的控制和数据交互。
c)访问SIM卡形态3：SIM卡上贴装薄膜SIM卡(带蓝牙模块)，贴膜SIM卡可以对SIM卡进行控制和数据交互，App通过蓝牙方式访问贴膜SIM卡，贴膜SIM卡接收约定的指令，对SIM卡进行操作；通过该方式，App实现了对SIM卡的控制和数据交互。
d)访问SIM卡形态4：SIM卡放置在USB等接口的读卡器内，读卡器插入安装有IM(及时通讯软件)的电脑上，这样，IM通过USB读卡器，实现对SIM卡的控制和数据交互。
e)访问SIM卡形态5：SIM卡放置在带接入IP网络模块(无线wifi模块或者标准网络接口)的simpool内，simpool能对SIM卡进行访问和控制，NRS服务器直接访问simpool，获取鉴权数据，无需App或IM进行传递，鉴权过程由NRS和simpool通信完成，手机端不再需要蓝牙盒子等周边产品。
接入NRS服务器的应用终端也存在多种形态,具体如下：
a)应用终端形态1：可以是App方式，在智能手机，pad上，安装专门的App软件，通过App接入NRS。
b)应用终端形态2：也可以是IM方式，在pc电脑上，安装专门的IM软件，通过IM接入NRS。
需要说明的是，本发明所述的方案有以下前提条件：
1、用户手机，安装专门的App应用软件
1.1、App能与SIM卡取得通信(通过蓝牙盒子等)。
1.2、App能通过3G/LTE/WiFi等方式，接入IP通信网。
1.3、App连接NRS服务器，通过OTT方式，接入国内蜂窝移动网络。
或者
2、NR方案功能植入手机系统
2.1、手机能通过3G/LTE/WiFi等方式，接入IP通信网。
2.2、手机直接访问待托管的SIM卡
2.3、手机连接NRS服务器，通过OTT方式，接入国内蜂窝移动网络。
虽然已经详细说明了本发明及其优点，但是应当理解在不超出由所附的权利要求所限定的本发明的精神和范围的情况下可以进行各种改变、替代和变换。而且，本申请的范围不仅限于说明书所描述的过程、设备、手段、方法和步骤的具体实施例。本领域内的普通技术人员从本发明的公开内容将容易理解，根据本发明可以使用执行与在此所述的相应实施例基本相同的功能或者获得与其基本相同的结果的、现有和将来要被开发的过程、设备、手段、方法或者步骤。因此，所附的权利要求旨在在它们的范围内包括这样的过程、设备、手段、方法或者步骤。
