Q: How do I access X4 secure calling?

A: Use an internet browser application on a computer, mobile phone, or tablet to access our service z.x4.com. You can invite one or more people to join you for either an audio or video call. Depending on your device, chat and/or screen sharing capabilities may also be provided. You may make free calls that last up to 5 minutes. Subscriptions for unlimited use are $15 monthly, paid in advance.

Q: May I cancel my subscription if I’m not satisfied?

A: Yes. Once $15 monthly payment has been made it is non-refundable. You may cancel any time and we will discontinue monthly billing

Q: I don’t use video. Isn’t this overkill for me?

A: Definitely not. If you prefer using X4 to make voice calls without video, or to chat via text, the service will still keep you safe from eavesdroppers. The First Amendment does not allow governments via their intelligence agencies to routinely listen and collect information on U.S. citizens. X4 will protect you and whomever you call from any and all such invasions of your privacy.

Q: How do I make a call?

A: Using the browser on your phone, tablet, laptop, or desktop, enter z.x4.com. When the calling screen loads, either login or click the free call option. If you choose a free call, follow the sequence of steps below.

Q: What are vanity URLs?

A vanity URL is a temporary link you can create instead of using system-generated links to control who can join your call. For example, if you choose movingMountain as your vanity URL, the invitee types in z.x4.com/movingMountain to join your call. People DO NOT have to be subscribers to join, but they must have a join code, either Vanity or system-generated.

The vanity option is provided to make it easier to connect. Vanity codes must be 8 characters and are case sensitive. Vanity URLs expire as soon as the call completes, just as with system-generated join codes.

Vanity URLs are more secure when they are longer, more random, and the more capital letters you include. System-generated codes follow these criteria.

When the control screen appears, click on the INVITE button located in the bottom right corner of the screen. Next, copy the unique link provided, called a join code, and send it via text or email to one or more persons you want on the call.

When someone joins your call, the user counter located on the top left increases, and a new window opens showing the display name they have chosen for themselves. People DO NOT have to be subscribers for you to call them. Each join code is valid for one call only.
