When you want to connect your IT system to the mobile network you have three basic options: IP SMS connection; GSM modem connectivity and Android SMPP connection. If you have a relatively small SMS traffic (less than 1000 SMS a day), you should choose the latter. This article describes through the example of a specific product that what you need and what you should do if you want to send SMS with an Android-based SMPP SMS Gateway application.
For SMS messaging using any kind of SMS software you need to install and configure one or more Service Provider connections. For this purpose the Short Message Peer to Peer protocol (SMPP) connection is a possible method. The SMPP protocol can be used to connect your computer directly to the SMS Center of the Service Provider (SMSC). By this way you can send and receive SMS messages over the Internet or over a private IP network.
In order to send SMS messages from your corporate system by using SMPP connection you need some kind of SMS gateway software (for example Ozeki NG SMS Gateway). Obviously, you need a PC (this software requires Windows operation system) on which you can install this SMS software then compose and send messages. In case of Android SMPP connection there is need for an Android smartphone (Samsung, HTC, LC, Sony Ericsson, etc.) and an Android SMPP SMS Gateway (such as Ozeki Android SMPP SMS Gateway) installed on your phone, as well.
First of all, make sure that your mobile phone is connected to the Internet, because you need to download the application from Google Play. You can use WI-FI or your Mobile Internet. After you have installed it, you need to launch it.
In the next step is to connect your SMPP SMS Gateway to the computer. How does this happen when using Ozeki Android SMPP SMS Gateway? After launching the application you will see some important information in the top left corner of the screen: Host name, Port number, Username, Password. You need to type these parameters in the management console of your SMS Gateway software (like Ozeki NG SMS Gateway). After you logging into your SMS software, add a new service provider connection by clicking on the appropriate menu item. Select the SMPP Connection then click on the install button. The Configuration panel of the SMPP Connection will appear. On the SMPP server settings tab you need to specify the followings: Host name, Port number, Username, Password. Use the parameters that can be found in your Android SMPP SMS Gateway application. In addition, you have to assign a telephone number and a specific service provider name to this connection.
After the basic settings, check the status of the connection by clicking on the logging panel. If you see that SMPP connection has been installed successfully, you are ready to compose and send a message.
Click on Compose a message button then fill in the form appropriately (select the type of your message, enter the telephone number of the recipient, compose your message, etc.) then click on Send/Ok. Thats it! If you use Ozeki Android SMPP SMS Gateway, you will get a delivery report about successfully sent messages, so you can make sure that the recipient has gotten your message.
