。MIDP 提供了基于Java 的接口、体系结构和库，用于电话的高级编程。它没有说明底层系统的物理功能。从技术上讲，您正在编程的设备甚至不能保证是电话 - 任何设备都可以决定实现 MIDP，只要它具有任何类型的双向、无线、可能间歇性的网络连接。
如果需要，您可以在此处查看规范的完整详细信息：

建议的设备硬件要求位于第 7-8 页。请注意“应该”一词的使用 - 设备实际上可能不具有所有甚至任何这些属性。
No.
MIDP gives a Java based interface, architecture, and library, for high level programming of the phone. It does not say anything about the physical capabilities of the underlying system. Technically, the device you're programming against is not even guaranteed to be a phone - any device could decide to implement the MIDP, as long as it has any kind of two-way, wireless, possibly intermittent, network connection.

The suggested hardware requirements for devices are on pages 7-8. Note the use of the word "SHOULD" - devices might not actually have all or even any of these properties.
GPRS基于各种服务提供商，例如airtel、vodafone。
The GPRS is based on various service provider such as airtel,vodafone.
