frequently asked questions


What is Wi-Fi calling?

Wi-Fi Calling allows customers to make and receive calls and texts (SMS & MMS) over a Wi-Fi (wireless internet) connection. Using Wi-Fi Calling is easy – customers won’t even know they’re making a
Wi-Fi call. Can any phone use Wi-Fi Calling? Any Apple iPhone 5C or newer is capable of using C Spire’s Wi-Fi calling.

What are the unique benefits of Wi-Fi calling?
  • Uses your existing phone number – no additional logins necessary
  • Extends coverage in areas where no cellular network reaches
  • Available at no additional charge
Does Wi-Fi calling go against a customer's included minutes if they don't have an unlimited calling plan?

No. These minutes are on the house. Talk all you want and never worry about using the voice minutes that are included in your plan.

How do I set up Wi-Fi calling?

It's simple. First connect to a Wi-Fi network. Go into settings. Go into Phone. Tap on Wi-Fi Calls. Slide the bar to allow Wi-Fi calls. Accept the terms and conditions. Make sure you've verified a valid 911 address for your physical address (a PO Box is not a valid 911 address). You are good to go.

Do I have to log int a Wi-Fi network to connect?

Yes, you must connect to a Wi-Fi network before your phone will automatically connect to that same network when in range. Once you’ve connected, you’ll be automatically connected when Wi-Fi is turned on. We recommend you have Wi-Fi connected at all times.

How do I log in to a Wi-Fi network on my device?

Go to Settings and select Wi-Fi. A list of available Wi-Fi networks will appear. Select a trusted network and enter a password to connect. After the first connection, the phone will automatically connect to that same network automatically when in range.

Once I activate Wi-Fi calling, will my phone always use Wi-Fi for voice calls if I'm on a Wi-Fi network?

No. Not all Wi-Fi networks are created equal. Some may be substandard and provide a very poor quality experience. Therefore, your C Spire phone will automatically prefer the cellular network. However, if it determines that the Wi-Fi network you are on would provide a better calling experience than the available cellular network, it will use the Wi-Fi network. Remember, the network indicator in the upper left corner of your phone will display C Spire Wi-Fi when using Wi-Fi Calling or will continue to show C Spire for cellular calls.

Are Wi-Fi calls comparable in quality to regular cellular calls?

Yes, when the device is in range of a reliable Wi-Fi network, Wi-Fi calls and cellular calls are similar in quality.

Are there any technical requirements for Wi-Fi calling?

For Wi-Fi calling to work, a customer must meet the following technical requirements:

  • Access to a Wi-Fi router with a high-speed internet connection
  • An Apple iPhone 5C or newer with a Carrier version of at least 10.27.1 or higher
  • A valid 911 address on file
Will it work in Airplane Mode?

Yes. As long as you are connected to Wi-Fi.

Can I receive picture and video messages as well as text?

Yes. SMS and MMS are both supported.

What happens if I'm on a Wi-Fi call but go out of range of the Wi-Fi signal?

If you get too far out of range of the Wi-Fi signal you will lose connection and your call will drop.

What happens if I am traveling internationally and need to call 911?

If you are traveling internationally and have an emergency, turn off Wi-Fi calling and use the mobile network. Calling 911 over Wi-Fi while travelling internationally won’t work.
