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.
