Sending text messages (SMS) via 12VoIP

You may use special characters; however the use of special characters '(characters like ç, @, €, etc.) may result in longer messages. To check how many messages would be needed to send your message, please use the SMS function in your myaccount, your desktop client or MobileVOIP client.


Using the 12VoIP client:

Select the SMS-tab in the application:

Your user name is already filled out in the Caller ID field. You can opt to show your mobile phone number as well. Just make sure your mobile number is entered in your personal profile and verified (to counter misuse of the SMS).

You can enter multiple recipients. Simply select them from your phone book or enter them directly in the text field (comma separated, use the full international number)

Use the "later" option to send your messages at a pre determined time.
