How to send special characters via GSM modem using the built-in HTTP server
On this page you can find a demonstration on
how to send special characters with GSM modems using the built-in HTTP server
of Ozeki NG SMS Gateway. Please follow the screen shots and video tutorial
below to learn the sending process.
System architecture
On Figure 1 you can see the process of sending SMS message
containing a special character. Ozeki NG SMS Gateway processes the HTTP request
that contains
special characters. Finally it will send the SMS message containing the special
character to the mobile phone of the recipient.
Figure 1 - System architecture
To demonstrate how to send special characters with GSM modem
using the built-in HTTP server I send a test message containing the character
Ä. These are the steps of the process.
Log into Ozeki NG SMS Gateway with your username and password. Go to GSM
modem connection and click on "Charsets" tab. Set the
"Charset set selection policy" to Enforce (Figure 2).

Now open HTTP Example page on www.ozekisms.com:
HTTP SMS API - sendmessage method. On this
page an example URL request can be found. Copy this example URL request and
paste it into the URL field of the browser (Figure 3).
Figure 3 - Paste the example URL request into the browser
Specify the phone number of the recipient mobile device
(e.g. your mobile phone numer) and
set the "Message type" to SMS:TEXT:FORMATTED in the URL (Figure 4).

Go to UTF8 URL Encode page on www.ozekisms.com:
UTF8 URL Encode. Enter the character to be
encoded and click on "Encode"
(Figure 5).
Figure 5 - Encode the character
The URL encoded version of the character will be returned.
It needs to be selected and copied (Figure 6).

Paste the URL encoded version of the character to the "Message
data" field in the URL request (Figure 7).
Figure 7 - Provide the URL encoded version as the message data in the URL
Ozeki NG SMS Gateway will returns an XML form about accepting
and forwarding the message (Figure 8).
Figure 8 - Ozeki NG SMS Gateway accepts and forwards the message
In the "Outbox" folder of the admin user in Ozeki NG SMS
Gateway you can see that the message containing the special character has been
sent (Figure 9).
