Can I cancel or remove Mobile Fax?

If you do not want to use Mobile Fax, you can remove the tile from your Home screen in the Personalize Tiles list.

Mobile Fax is a permanent feature of the HP Smart app, similar to printing photos or scanning. It is automatically included in newer versions of the app.

HP does not require payment or a subscription to use the Mobile Fax service during the free trial period. 30 days before the end of the free trial period, HP offers paid service plan options. You can opt out at that time, or cancel an existing subscription at any time.

What are the Mobile Fax system requirements?

The following requirements must be met before you can use Mobile Fax.

Android and iOS

  • HP Smart app version 7.0 or later

  • Android 6.0 or later or Apple iOS 11 or later

Windows 10

  • HP Smart app version 11.0 or later

Why should I send a fax instead of an email?

Faxing can be more secure than email.

A fax is encrypted, and the files you send are only visible to you and the recipient. It is a safe way to send personal data such as medical history or sensitive information such as legal contracts.

How do I know if my fax was received?

After you send a fax, a Fax Delivered or Delivery Failed message displays in the HP Smart app.

Previous faxes are listed in Fax History as delivered or failed . Find Fax History in the More menu in Mobile Fax. If a fax does not display under Sent, check the Draft list.

Sent items in the Fax History list

How do I cancel a fax?

You can only cancel a fax before it has been delivered. When a fax is canceled during a transmission, the recipient might still receive part or all of the fax.

How do I find or save my fax history?

Retrieve prior faxes from the fax history window.

  1. Click the Mobile Fax tile, click the More icon , and then click Fax History.

    Opening Fax History in the HP Smart app
  2. Click any fax to view the details of that fax.

  3. Click Export Fax Log to save a fax to your mobile device, computer, or cloud account.
