Certain special characters (e.g. in the Greek language but also certain symbols) will require your SMS to be sent in Unicode text encoding.
This will limit your character count per SMS (part) and can thereby increase your cost. We offer a Transcoding function, that will automatically transform certain Unicode characters to GSM characters to prevent a higher character count & cost. To enable transcoding do the follow steps.
1. Navigate to Settings
2. Enable the transcoding switch
3. Click button Save
