To send and receive faxes, SMS (text message) and text-to-voice messages, you must purchase prepaid messaging credit. 

It is important to check your credit balance regularly. It is your responsibility to top-up your credit when it’s getting low. If you run out, faxes, SMS and text-to-voice messages will no longer be sent from your account.

Note: You can enable auto top-up.
​  

To purchase, go to the Messaging Settings page and select Purchase Credit (as shown below). 

 Alternatively, navigate to your Subscription page and click on Purchase Credit under the Messaging Credit section.
​  

In the pop-up window, enter the amount of credit you wish to purchase and press Purchase.

Note: the payment may take 48 hours to be processed.

We will send a tax invoice to your email address. You can retain this email for taxation purposes. If you would like a PDF copy of the receipt, click on the link in the email.

If you would like Kalix to automatically top-up your messaging credit after the balance reaches a certain amount, please follow the steps below:

1) Under the Messaging Credit section of Messaging Settings page or your Subscription page, select Manage. 

2) On the pop-up window select the Automatically Top-up Low Balance.

2) In the Trigger Amount field, enter the credit balance amount that will trigger automatic credit top-up.
​
3) Input the credit amount you would like to be automatically added in the Top-up Amount field. 

4) Click Save.
​

Note: if setting up messaging credit for the first time, please purchase credit first before setting up auto-top up. Auto top-up will only occur after the first credit purchase.
