How to Use WiFi to Make Calls With AT&T Phones

By Heather Harris

VoIP, or Voice over Internet Protocol is the technology that makes it possible to talk live via the Internet. Many cellular phones are wireless-Internet enabled. The Skype application provides a simple, user-friendly way to access VoIP to make user-to-user calls without using their AT&T airtime minutes. With a few easy steps and the right equipment, you can join the ranks of those who use Skype to make free calls over WiFi, or wireless fidelity Internet.

Things You'll Need

  • WiFi-enabled cellular phone
  • Wireless Internet access

Using Skype to Make VoIP Calls

Step 1

Use your WiFi-enabled phone to connect to a wireless Internet connection. If the connection is secure, you may be prompted to enter a password to be allowed to connect.

Step 2

Use your phone's browser to access Skype.com and follow the prompts to download and install the free Skype application. If you are using an Apple iPhone, open the App Store from the iPhone's main menu, press the "search" button, and enter "Skype" in the search field. Once you have located the Skype app page, press "install," and enter your Apple I.D. if prompted.

Step 3

Locate and open the Skype app on your phone. Follow the prompts to create an account. You will be required to accept terms of service before you can proceed. Be prepared to enter your full name, create a username and password and provide a valid e-mail address.

Step 4

Follow the prompts to place a test call. You will be asked to speak a message, which will be played back to you. If you can hear your message, your phone is configured correctly to use VoIP. If you cannot hear your message, you will be prompted to troubleshoot your phone's audio recording settings.

Step 5

Locate the contacts menu within the Skype app. Use this menu to search your phone's directory, the Skype directory or manually add a phone number.

Step 6

Select the contact you want to call and follow the prompts to make the call. Depending on the other person's settings, you may first be prompted to submit a request for permission to contact them via Skype.
