Pros And Cons Of Wifi Calling

Wifi calling is a nice thing when you want to make calls in places where you would otherwise have no reception. Wifi calling can also save a lot of money abroad. We show you the pros and cons of wifi calling and show you how you can make calls over WiFi.

What Is Wifi Calling?

With Wifi-Calling, you no longer make calls via the cell phone network, but via the data connection of a WLAN network. So you no longer need GSM, UMTS or LTE to be able to make calls using your cell phone or smartphone, just a data connection from the WLAN router. In contrast to VoIP services and messengers, with WiFi calling everything goes as usual with your own telephone number and the same functions, no third-party apps or user accounts are required.

Here are number of Pros And Cons Of Wifi Calling.

Advantages Of Wifi Calling

Telephoning via WLAN has a number of advantages, and these do not only affect the network.

  • Better reception: Cellular reception in closed rooms is often difficult. With wifi calling you can be reached in places where this is not usually the case.
  • Fast connection establishment: With Wifi-Calling, the telephone connection is significantly faster than with normal calls via the cell phone network.
  • Voice quality: The voice quality is not always the same with wifi calling, but on average it is better than via mobile radio.
  • No roaming charges: Anyone who calls via wifi calling is in the home country for the provider, so there are no roaming charges. This is less important in Europe, but it is in other regions of the world.​​

Disadvantages Of Wifi Calling

The main disadvantage of wifi calling is the dropouts that occur when you move during the call. This can have two causes:

  • Switching from one hotspot to the next: In large WiFi networks, wifi calling comes in difficulties when you move from one hotspot to the next. The conversation often breaks off, sometimes there is only a brief deterioration in quality.
  • Switching from WLAN to cell phone: A handover from a call via wifi calling to one in the cell phone network is only possible if it is an LTE network. Everything below always results in a termination, so you have to call again or have someone call you.​​
