Why You Should Enable Wi-Fi Calling On Your Phone?WiFi Calling On This Phone

Apart from the reasons listed previously in this article. There are many other reasons that will convince you of using iPhone Wi-Fi calling.

  1. If you are an avid traveler who loves to explore the world, you must enable this awesome feature on your phone. This will let you place and receive calls over WiFi from your phone number. The roaming charges will not be applied if you are using this feature. Your carrier will only charge you international calling rates. By the way, there are other free apps like Facetime, Skype, Whatsapp, Google Hangout that you can use free of charge. But these apps only work if the other party you are trying to communicate uses the same apps.
  2. There are many people who love to live in a remote location near to nature where there are no carrier towers to provide telecom services. I know many people in the US who follow nomad lifestyle and use Wi-Fi call over there carrier in order to maintain communication with the outside world.
  3. Areas with no consistent mobile network, meaning sometimes you get the network sometimes not or there will be disturbance or cut-outs during the calls. I know this makes any caller very irritated.
  4. The other thing is your iPhone will consume more battery power when continuously trying to connect to a carrier network in an area with a fluctuating signal. The best thing to do in this situation is to turn off the carrier network and start using Wi-Fi calling on iPhone or other supported devices.
  5. In case there is an emergency and you want to call 911, what’s the better option than placing a Wi-Fi call.
  6. Wi-Fi hotspots are increasing every year as compared to mobile towers. Implementing hotspots are way cheaper than adding mobile towers to the areas. I have a strong feeling that mobile companies in the future will use Wi-Fi calling instead of regular analog transmission.

How Wi-Fi Calling Works & Other Important Details

When you place a call using your iPhone Wi-Fi calling also called VoWiFi (Vice Over Wi-Fi). The call packets get routed to your registered carrier using Unlicensed Mobile Access (UMA) technology.

There is a device located at the mobile network tower called GAN Controller (GANC) which receives the Wi-Fi call packets from the internet and transmit it through the phone network as if the call is placed using the regular network and not Wi-Fi.

How much does Wi-Fi calling cost?

You will not be charged extra while using VoWiFi (WiFi Calling) feature. The carrier will deduct the minutes or the balance used by the consumer from its system.

If you are calling locally, local rates will apply. International call rates will apply if you are placing the call internationally. Roaming will be always free of charge.

However, you can use apps like Whatsapp that support VOIP tech for calling and texting purpose without having to spend a dime. One of the advantages of using Wi-Fi calling is that the receiver will see your phone number on their screen.

Is VoWiFi supported by every Carrier?

The answer is NO! Wi-Fi Calling is not supported by each and every mobile carrier out there in the market.

To use iPhone Wi-Fi Calling you should be registered on a supported carrier. Moreover, Wi-Fi calling is not available to every country on this earth. You can find out the supported carrier and countries using this link.

These are the major carriers which support this feature:

  • Sprint: You can use Sprint Device support to get more information about your device and WiFi Calling.

You might need to “Update Emergency Address”. This address is used by emergency response service like 911 to track your details with the help of your carrier in case you need help.

Notice the screenshot above, there is an option “Add Wi-Fi Calling For Other Devices”. If toggled On, this will allow you to use WiFi Calling with other Apple devices.

Your iCloud account acts as a medium between your iPhone & other devices. So to use this option you must have an iCloud account that I am sure every iPhone user has.

On Other Apple Devices:

The other devices that you want to add to your WiFi Calling devices list should have the latest version of the iOS software.

Adding other devices in the calling list helps when you do not have your iPhone near you.

  1. I will assume that you already turned on “Wi-Fi Calling” and “Add Wi-Fi Calling For Other Devices” using the steps mentioned previously.
  2. On your other Apple devices, log into iCloud and FaceTime with the same Apple ID and password that you use on your iPhone device. This is important, failing to do so will not add other devices to the Allow Devices list.
  3. Next step is to enable Wi-Fi Calling:
    • On your iPad or iPod touch, go to Settings > FaceTime > Calls from iPhone and tap Upgrade to Wi-Fi Calling.
    • On your Mac, open FaceTime and choose FaceTime > Preferences > Settings and select Calls From iPhone > Upgrade to Wi-Fi Calling.
    • Please note that Wi-Fi Calling isn’t available on Mac Pro (Mid 2012).
  4. You will need to verify your other devices using the 6 digit code that you will get on each device after you follow the above steps. Just enter the 6 digit code on your iPhone when prompted and tap “Allow“.

Apple Watch does not need to be enabled for Wi-Fi calling. When the Wi-Fi calling is enabled on other devices and you get the call on your iPhone, your Apple Watch will ring and you can attend or make calls from it.

Let’s see what to do if WiFi Calling is not available on your iPhone or other devices.
