UDH
For sending ringtones and logos,etc, you have to include the User Data Header (UDH). We provide pre-defined message types
that allow you to send binary SMS data such as ringtones and logos to Nokia phones. However if you have an application
that creates the UDH and DATA fields automatically you can set these parameters directly through the Clickatell API.
Concat
According to GSM standards, SMS messages may only be 160 characters in length. You can, however, split a longer message across
multiple SMS messages. SMS concatenation is also used when sending logos and ringtones, meaning that your logo may
cost more than one message credit to send to a recipient, depending on the length of the binary SMS that is created for the
delivery of the message.
Unicode
In order to send foreign or non-standard characters such as Chinese, Arabic SMS etc, you need to send
the message in Unicode. If you have an application that already sends Unicode (UCS_16), you can simply
send the message through Clickatell's SMS Gateway with one of our API's. Sending SMS
using Unicode has certain constraints, such as the message length that is shorter than with 7-bit (160 text) or
8-bit (binary, EMS, Logos etc). The character limitation for a Unicode message is 69. For more info on
unicode, see www.unicode.org.
Binary
We provide pre-defined message types that allow you to send binary SMS data such as ringtones
and logos to Nokia phones. However if you have an application that creates the
UDH and DATA fields automatically you can set these parameters directly through the Clickatell API.
Alpha
The ability to set an alpha source address when submitting a message. Some destinations
offer the ability to set a customised source address on an SMS message. If "alpha" is indicated
then we have the ability to set a custom alpha source address for your message. Please note
that this is operator dependent and is not a guaranteed feature.
Numeric
The ability to set a numeric source address when submitting a message. Some destinations
offer the ability to set a customised source address on an SMS message. If "numeric" is
indicated then we have the ability to set a custom numeric source address for your
message. Please note that this is operator dependent and is not a guaranteed feature. |
