How are SMS messages handled?

The message content is limited to 160 characters for a “standard” SMS.

The list of accepted characters is as follows:

A B C D E F G H I J K L M
N O P Q R S T U V W X Y Z
a b c d e f g h i j k l m
n o p q r s t u v w x y z
0 1 2 3 4 5 6 7 8 9 SP LF CR
ESC ' ? ( ) [ ] < > . + - =
, ; : " ! ¡ % ¿ @ £ $ / *
¥ # ¤ & Ä Å Æ Ç É Ö Ñ Ü ß
à ä å æ é è ì ò ö ñ ù ü  

You can send a “long” message of up to 5 SMS of 153 characters. Message concatenation uses 7 characters per concatenated message.

Each time an SMS payment order (successful or failed) debits your SMS balance with:
  • One unit for a “standard” SMS of 160 characters,
  • Between 2 and 5 units for “long” messages.

When the balance is below the alert threshold specified during your registration, an alert is sent by e-mail.

If the balance is depleted, an error message will appear:
  • On the screen when creating a payment order via the Back Office,
  • In the response when creating a payment order via Web Services,
  • In the transaction details in case of an IPN.
