SMS is the abbreviation of those words. How to send SMS?

SMS(Short Messaging Service) is the earliest short message service, and it is also the most popular short message service at present. At present, the length of this short message is limited to 14 bytes, which can be text. SMS is welcomed by the public because of its simple and convenient use function, but it is always the first generation wireless data service, and there are technical standards restrictions in content and application.

what is SMS?

the short message server enables mobile phones (including Pocket PC Phone) to send short messages using GSM network, which has many interesting functions:

an SMS message can contain up to 16 characters (even binary).

SMS is a store and forward service. In other words, short messages are not sent directly from the sender to the receiver, but are always forwarded through the SMS center. If the recipient is disconnected (the phone may be turned off), the message will be sent when the recipient connects again.

SMS has the function of sending confirmation messages. This means that SMS is different from paging, users do not simply send short messages and then believe that the messages have been sent successfully; Instead, the short message sender can receive a return message to inform them whether the short message has been sent successfully.

SMS messages can be sent and received synchronously with GSM voice.

SMS messages are charged by message, so they are much more expensive (per byte) than data sent through IP-based networks (for example, using GPRS [General Packet Radio Service]).

to use SMS, a user needs to subscribe to a mobile network that supports SMS, and the user must be enabled to use SMS. Users need to have a destination to send or receive short messages. This destination is usually another mobile phone, but it can also be a server. Finally, users also need to have a mobile phone that supports SMS, and they need to know how to send or read short messages with their specific mobile phones.

why use SMS?

for application developers, the immediate solution to connect Pocket PC Phone to the server may be through an IP-based network, such as the Internet. The advantages of this approach include: common standard protocols already exist, and communication tools are ready-made.

however, in some cases, IP-based network is not the most effective transmission mode. Active or even automatic connection takes up valuable time, and it is impossible to connect during a call. If there was a way to connect to the server instantly even when talking, what would it be? Since Pocket PC Phone can send SMS messages, it may be a way to realize it.

Instant connection is usually very useful when mobile workers need to notify important events to business process applications. It may be a salesman who informs the server that there is a new order, or a truck driver who has just delivered the goods.

on the server side, there are many solutions to receive SMS messages and forward them to other systems. Examples are products of MobileSys, Inc and Smartserv Online, Inc In this article, we will further discuss the SMS performance of Pocket PC Phone.
