In the past, many people relied on tools like Skype for virtual communication. But, with the omnipresence of Wi-Fi hotspots, it’s become easier than ever before to move ahead with Wi-Fi calling. Moreover, many telecom providers in India have included Wi-Fi calling under their services. But, do you know exactly what Wi-Fi calling is? Well, scroll through this article to know more about how Wi-Fi calling works.
Wi-Fi calling is nothing but a feature that enables you to make and receive phone calls. This means that you enjoy Wi-Fi and phone calls. This is especially useful in regions which experience weak cellular signals within the building. Such type of calling also is helpful when Wi-Fi is available but the coverage is poor. You can also expect better call quality and reliability when the mobile network service is limited. Moreover, you can use this feature when the Wi-Fi connection is available but the coverage is poor.
A process is usually followed when someone is connecting with an individual through the Wi-Fi connection.
>> Whenever you enjoy Wi-Fi and phone calls, the data packets will move across the internet through the network. In that case, the network is nothing but the Wi-Fi network to which the device is connected.
>> Afterwards, the carrier’s network infrastructure plays a role. These comprise special servers which are capable of handling VoIP traffic.
>> A bit later, the data packets are converted into audio and sent to the recipient’s end. This helps in listening to your voice just as if it was on a usual call.
>> In some cases, if you are not within the Wi-Fi range, then the mobile phone will switch back to the cellular network. At those instances, the call will not get dropped off. However, this can vary depending on the mobile device and the carrier.
We hope by now that you have understood how Wi-Fi calling works. Beyond this, It’s pretty easy to make Wi-Fi calls. But, the steps may vary depending on the carrier and the device. Let’s check out how you can proceed with Wi-Fi calling.
1. Ensure Compatibility
First and foremost, you need to check whether the mobile phone has the Wi-Fi calling feature. While the most popular smartphones offer this feature, it’s always a good idea to confirm.
2. Enable the feature
Now, you have to unlock the mobile phone and go to the ‘Settings’ menu. Under this section, you have to check for the ‘Wi-Fi Calling’ feature. If this option is not present under the section, then check for ‘Voice over Wi-Fi’’ option. Later ,you have to proceed by following certain instructions that appear on the touchscreen.
3. Establish the connection
Soon after following the instructions, you have to confirm whether the device is connected to a secure W-Fi network. This can either be within your residence or workplace. Besides, the connection may also be established with a Wi-Fi hotspot in the vicinity.
Eventually, with the Wi-Fi enabled on the device, you can either converse with someone or receive voice calls. This is quite similar to dialing a number and connecting with someone. But, for a seamless connection, you will observe that the device will switch between the networks as and when it’s required.
There are many benefits of Wi-Fi calling. It is helpful when the cellular signal is unreliable. So, let’s check the pros ahead.
Now, let’s check how Wi-Fi calling differs from Cellular Calling.
| Feature | Wi-Fi Calling | Cellular Calling |
| Network Used | Uses Wi-Fi networks to route calls |
Uses cellular networks like 3G, 4G or 5G for calls.
|
| Coverage |
Works well in areas that have Wi-Fi but poor cellular signal .
|
Coverage depends on the range of the cellular network and signal strength.
|
| Call Quality | Can offer better call quality provided that the area has a strong Wi-Fi connection. |
Call quality can vary depending on cellular signal strength. Network congestion can also affect call quality.
|
| Cost | Costs can be low, especially for international calls. |
Standard charges apply, but they can be more for roaming or international calls
|
| Call Roaming | May work internationally over Wi-Fi, often with lower rates |
Roaming charges are applicable especially for international calls
|
| Battery Usage | Generally uses less battery when connected to Wi-Fi |
May use more battery power in areas with weak cellular signal because the device may find it tough to maintain the connection.
|
| Device Compatibility | Requires devices that support Wi-Fi calling. |
Supported by almost all mobile phones.
|
| Internet Dependency | Needs an active and strong Wi-Fi connection. |
The connection relies on the cellular tower only.
|
Wi-Fi calling can be a suitable option only when the cellular coverage is below your expectations. You can connect with ease when Wi-Fi is present in remote locations or basements. But, if you are trying to connect with someone from a cafe or a hotel, then Wi-Fi calling can be unreliable. This is because many individuals at the public space are sharing the connection’s bandwidth. On the other hand, Wi-Fi calling may not be ideal when the mobile device doesn’t support Wi-Fi calling. Hence, before you think about calling through Wi-Fi, check for device compatibility.
Finally, after understanding how Wi-Fi calling works, you must have realized its usefulness. You can also rely on such a type of calling without any extensive setup. In case you’re in deep trouble during an emergency, then Wi-Fi calling can help to stay connected. While you’re on a tour, you can also consider calling through Wi-Fi by avoiding the roaming charges.
