配置注意事项:
若使用 GSM 调制解调器(比如:TC35,MC45,MD720-3)的拨号连接方式(CSD 程序:电路交换数据服务)建立数据连接,那么安装在 GSM 调制解调器内的 SIM 卡需要启用网络运营商提供的CSD 数据服务。.
SIM 卡被启用后,它可以拨号连接到其他的GSM 设备,连接到固定网络中其他的模拟或数字ISDN 调制解调器。
对于只能启用语音服务的SIM 卡,就像普通手机的SIM 卡一样,不能被用于数据通信。
当GSM 调制解调器通过GPRS (数据包-面向数据的服务)建立数据连接,如 MD720-3, MD740-1,那么SIM 卡必须启用 GPRS 数据服务。推荐为 GPRS 服务保留固定的数据流量(如 30MB)。
如果没有使用数据连接,仅发送SMS 文本消息,那么它和数据服务的启用是无关。
所有的 SIM 卡能够自动启用发送 SMS 文本消息功能。
注意:
要使用SIM卡的调制解调器通过TS适配器和远程服务建立远程连接,SIM必须满足上述属性。
如果使用笔记本通过GSM移动电话访问 TS 适配器,那么 "CSD 数据服务" 也必须启用. 这意味着如果"CSD 数据服务" 启动, 那么使用GSM技术的计算机就可以利用远程服务访问使用模拟/ISDN/GSM技术的系统。
而且服务供应商会提供额外的号码(GSM 数据号) 为每种特殊的服务, 像CSD的数据交换服务。
在这种情况下需要向服务供应商咨询。

Configuration Notes:
If data connections are set up by the GSM modem (for example, TC35, MC45, MD720-3) via dial-up connections (CSD procedure, circuit-switch data service), then the SIM card implemented in the GSM modem must be enabled for CSD data service by the network provider.
After the SIM card has been enabled, it is possible to set up dial-up connections to other GSM devices and to analog or ISDN modems in the landline network.
SIM cards in which only the voice service is enabled by the provider, just as in a normal mobile phone card, cannot be used for data communication.
If data connections are set up by the GSM modem (for example, MD720-3, MD740-1) via GPRS (package-oriented data service), then the SIM card used must be enabled for the GPRS data service. Reserving a fixed data volume for the GPRS service (for example, 30MB) is recommended.
If no data connections are used, but only the card for sending SMS text messages, then enabling for data services is irrelevant.
All SIM cards issued by the network providers are automatically enabled for sending SMS text messages.
Note:
The SIM card used in a modem over which a teleconnection is to be set up with TS Adapter and teleservice must also fulfill the above-mentioned properties.
If you access a TS Adapter from a laptop with a mobile phone via GSM, then the "CSD data service" must also be enabled. This means that if the "CSD data service" is enabled, then you can access a system with analog/ISDN/GSM technology with teleservice from your computer with GSM technology.
There are providers who assign an additional number (GSM data number) for each additional service, like CSD data service.
Please sort this out with your provider as the case may be.
