Wi-Fi calling vs. VoLTE – which one is better?

With advocates for both VoLTE and Wi-Fi calling, how do you decide the better option to use? It is an important choice you will make regarding your preferred communication method.

VoLTE and Wi-Fi calling are the major wireless standards that handle data and voice packets, and they are quite popular because of the innovation possibilities and efficiency they represent.

VoLTE is the better method because it helps in data transfer and voice calls on a cellular network, while Wi-Fi calls operate in the same way but only over a Wi-Fi network. Before deciding on which method to use, you will need to ask yourself some important questions, such as the location you frequently use when making calls and your signal strength. 

Why should you select VoLTE over Wi-Fi calling?

The aim of VoLTE is versatility in all locations, as it aims to provide opportunities to make voice calls over a 4G LTE network, rather than over a 3G or 2G connection.

VoLTE Pros

Offers superior quality of voice and video calls

Voice calls on VoLTE networks are very good compared to earlier networks because the connection captures sound faster and uses more frequencies, creating HD results. It eliminates background noises as well, so there is no worry when taking calls even in loud places.

Its support for video calls is strong as well, thanks to its use of the HD video codec H.264, allowing network operators to apply video services to their networks without requiring the reliance on apps like Skype.

Improvement in connectivity

Its connections are twice as fast and the coverage range is greater compared to 3G and 2G networks. This is because it is highly dependent on existing networks, making it easier to upgrade to it compared to VoWiFi.

Multitasking

Since VoLTE allows you to use mobile and data networks, you can perform multiple tasks like taking phone calls and using your phone apps simultaneously without compromising the quality of both connections.

VoLTE Cons

Unavailable on all smartphones

VoLTE is a 4G LTE technology, so older phones do not have it in their network setup. However, this is not a major issue, as newer phones support its deployment.

Why choose VoWiFi over VoLTE?

There are certain locations where Wi-Fi calling works better, making it a better alternative to relying on cell towers and network carriers.

Pros of Wi-Fi calling

Convenience and simplicity

With Wi-Fi calls, you do not need to worry about not having a cellular signal. The only component you require is the latest Wi-Fi calling software, making it very easy to send media, texts, and calls when the Wi-Fi indicator is on.

This makes it a good alternative if you operate in an indoor location with poor cellular reception without forcing you to upgrade your smartphone or install new equipment.

Clear calls

Since Wi-Fi calls do not rely on mobile signals, the call quality sounds good – even though it may not be in HD quality. If you operate a business, this makes it more efficient for your communication.

More cost-efficiency

The use of VoWiFi saves you money because it allows you to call for free – even when talking to people overseas.

Cons of Wi-Fi calling

Inadequate strength of the signal

Sometimes you may experience issues with Wi-Fi calls in specific places like crowded venues since shared bandwidth results in degradation of the connection quality.

Some devices do not support it

Similar to VoLTE, not all devices will support Wi-Fi calls – unless they are smartphones or tablets.

Data fees sometimes apply

If the Wi-Fi signal is weak, the device will default to a cellular connection and increase the fees you will need to pay to access the same service.

Differences between VoLTE and VoWiFi

Conclusion

Many benefits that apply when using both VoLTE and VoWiFi, though we find that VoLTE is more versatile with the results it achieves in both data and voice transfer due to its reliance on cellular networks. Wi-Fi calling on the other hand, will work better if you do not want to rely on cellular networks and have strong and reliable Wi-Fi available to you at all times.

FAQs

1. Do VoLTE calls drain a phone battery faster?

No. On the contrary, it saves battery life because your phone does not need to switch between 3G and 4G networks when you make calls.

1. Can I use Wi-Fi calling while traveling?

Yes, and it is very convenient in this case.
