Kalix offers you the ability to purchase your own unique phone numbers to send and receive faxes, SMS (text messages), and/or text-to-voice messages (computer-generated voice messages). You can also port an existing number (continental United States only) over to Kalix. By using a dedicated number, you will be able to receive faxes and SMS messages from anyone.

There is an ongoing subscription for maintaining a dedicated number. It is added to your monthly or annual subscription as an ongoing payment. Costs for American, Australian, and Canadian numbers are listed below. We support other countries, please contact us for details.

On purchase, you will be charged the pro-rata amount for the rest of the current billing period. 

  For example: You are on a monthly Kalix subscription. The cost of your dedicated number is $3 a month. There are 15 days until your next subscription payment. You will be immediately charged $1.50c and a $3 extra ongoing charge will be added to your monthly subscription payment. 

You are also responsible for paying the costs associated with the sending and receiving of fax, SMS (text) and/or text-to-voice messages via the purchase of messaging credit. Messaging credit must be purchased before use. For pricing click here. 

Note: you are not required to purchase a dedicated number in order to use Kalix's faxing functionality. Kalix also offers you the ability to send fax, SMS and text-to-voice messages for the message cost only. Your ability to receive faxes and SMS is limited, however, to clients who have already received a fax from you.

After the porting is complete, all faxes and/or text messages sent to your number/s will go directly into your Kalix account. You can also cancel your current carrier.

The process typically takes 2-4 weeks, and we will provide updates via email.

There is no additional cost to port a fax or phone number, however, charges will be added to your monthly or annual subscription as an ongoing payment (the same cost as purchasing a dedicated number) as a management fee. See the Cost section above for details). For the first payment, you will be charged the pro-rata amount for the rest of the current billing period (as per purchasing a dedicated number). 

There is required paperwork to be completed before we can start the porting process. This includes the completion of an Authorization Form and the provision of your latest monthly bill for the number to be ported. 

Please email [email protected] to start the porting process, we will send you the paperwork to complete securely online. 

If you unsubscribe from Kalix, your dedicated or ported numbers are canceled on the final day of the subscription period.

You are able to port your number/s away from Kalix if the porting request is submitted before the end of your subscription period. To do this you will need to submit a request with the carrier to which you are porting your numbers to. 

Most carriers require you to fill out a Letter of Authorization (LOA), on which you may need to provide the Account SID and the service address. Please contact [email protected] to request these details. 

You can also cancel or delete dedicated numbers at any time. Navigate to your Messaging Settings. Scroll to the bottom of the page, where the Dedicated Numbers section is located. Click on the trash can associated with the number you are deleting.
