Can you make phone calls on 4G LTE?

When 4G calling has been enabled on a smartphone, phone calls can be carried over 4G which means you don’t drop down to 3G or 2G when you make a call. You don’t have to do anything special to use 4G calling, just make a phone call and it will do its magic.

First, toggle on and off the Airplane mode. On most Android phones, you can toggle on/off the airplane mode from the Quick Settings panel. If not, you may go to Settings → Mobile Networks → Airplane mode. Turn on Airplane mode for about 30 seconds or more. Turn it off again to reconnect your network.

Does 4G affect voice calls?

4G (LTE) doesn’t support voice calls in the simplest implementation, it is only a data transfer system; your phone has to swap to a 2G or 3G cell to make a voice call using a technical process called “Circuit Switched Fallback’” (or CSFB).

Why can’t I make calls on 4G?

If your carrier does not support VoLTE, and your device is only allowed to access LTE, you can’t make calls. Change to ‘LTE/WCDMA (Auto)’ (4G/3G) or ‘LTE/WCDMA/GSM (Auto)’ (4G/3G/2G) mode so the phone can automatically change to a network that supports voice codecs.

Why do my phone calls take so long to reach 4G?

At times, after voice calls are completed over a 3G network, the devices fail to register to a 4g network using the handoff mechanism which is to be invoked when a voice call is terminated. This results in the handset relying on low-speed 3g networks for longer duration than expected.

Do I need a 3G or 2G network to make calls?

This means that – if you have a 4G handset, you will still need to use a 3G or 2G network to make a voice call. How does this happen? If you are within a 4G circle, all your data transactions will happen over the 4G network and will use the EPC framework and infrastructure.

What happens when a voice call goes to 3G?

When a voice call comes in while doing a data transaction, as described in all sections above, the network falls back into 3G and the data transfer happens over a 3G PS network. The capacity of a 3G network is almost 1/25 of a IP packet switch network.

Can voice be carried by packets in 4G?

In 4G, voice can be carried by packets if the technology used is VoLTE (Voice over LTE), even in this case the charging system counts the duration of the call not the transmitted kilobytes.
