Limitations

There is always room for improvement, and the same goes when talking about wifi and VoIP calling services. Here are a few challenges faced by wifi calling services.

Data consumption

If you are not in a wifi zone or if you are not using the wifi that is installed at your home, school or whichever place you may be in, wifi calling services can make use of your data plan that you may have recharged for your phone. It is believed that about 1mb of data can be used if you make a voice call for 1 minute and about 8mb of data can be used if you opt for making a video call. So data consumption may increase if you do not make use of wifi facility available in your area.

Wifi connection is a must

It is vital to have a proper internet connection for making a wifi call. And, also it is necessary that both the parties make use of LTE voice coverage so that the call is established between the two parties.

Signal strength may vary at times

There are chances that there may be variations in the signal strength, thus it may affect the bandwidth that is required for making a call. In such case the call quality may get hampered, restricting a high-quality voice call. Also, when more people try to connect their phones using the same wifi network, the chances are that the signal strength may go weak due to multiple users making use of the network at the same time. This may further weaken the quality of the wifi call in such a case. This usually happens when you are using the wifi network at public places such as railway stations, airports, etc.

Data transfer delay

Many times, we may also face a delay in the transfer of data while making use of wifi calling services. Sometimes what a person says from one end is received by the user at the other end after a short interval. Thus a delay occurs during transmission of calls causing inconvenience.

Not supported worldwide

You may not expect this wifi calling facility to be in widespread usage all over the world. A few countries are still to adopt this technology.

The Bottom Line

It can help you connect to people from any part of the world at lower prices, at the cost of the data plan or wifi network that you use.
