Sprint Mobile was renowned as one of the leading telephony providers in the United States. The company has since merged with T-Mobile in 2020 to become one of the most extensive cellular networks, with over 50 million subscribers in the country.
Sprint Wi-Fi calling is one of the most attractive offerings that has made the merged company more popular in the telco industry. This feature has been around for a while, but many customers are yet to make the most of it.
So, in this post, we will explain what Sprint Wi-Fi calling is all about and everything you need to know to make the most of this feature.
What is Sprint Wi-Fi Calling?
Sprint Wi-Fi calling is a voice service by Sprint/T-Mobile that allows customers to place and receive calls over a Wi-Fi connection rather than a cellular network. You can also send and receive text or multimedia messages and place video calls over your wireless network.
The service is available on selected Android and iOS devices and does not require a separate application or login credentials. It is also important to note that Sprint Wi-Fi calling is available at no additional cost for calls made within the U.S. (including Puerto Rico and Virgin Islands). International rates apply to calls made outside the specified territories.
Wi-Fi Calling Explained
How Does Sprint Wi-Fi Calling Work?
Sprint Wi-Fi Calling works like any other Voice over IP application (e.g. WhatsApp or Skype). The feature allows you to make and receive calls over your Wi-Fi connection rather than your cellular network.
When enabled, Wi-Fi calling switches your phone to use your Wi-Fi network to place and receive calls in areas with weak or no cellular connection. It transmits cellular data packets through a Wi-Fi connection across the internet to the receiving device and vice versa.
Interestingly, all voice calls and text messages will appear ordinary, and the recipient won’t realize you are using the Wi-Fi calling feature. However, a Wi-Fi icon may appear on some phones and tablets.
To ensure you stay connected, your phone will also switch to your cellular LTE network automatically if you move outside your Wi-Fi coverage. However, the VoLTE toggle must be active for in-call handover to work.
Here are the steps to activate VoLTE on your phone:
- Go to Settings.
- Tap Connections or Network & Internet.
- Tap Voice Networks or Mobile Networks.
- Toggle VoLTE to enable in-call handover.
Since Sprint Wi-Fi calling is only available on selected devices, your smartphone must support this feature for it to work. Some carriers require your phone to have HD voice settings enabled, but this is not the case with Sprint/T-Mobile.
How to Activate Sprint Wi-Fi Calling?
If your phone or tablet supports Wi-Fi calling, activating the feature should not be an issue. You only need to find the Wi-Fi calling option on your device and tap it to activate it.
Here are the steps:
- Tap the gear icon to go to Settings.
- Tap Connections or Network & Internet.
- Tap Voice or Mobile Networks.
