4G calls, also known as VoLTE (Voice over LTE), uses the 4G (LTE) network instead of 2G or 3G network for transmitting voice calls by transforming voice to data. If the 4G signal is not strong enough or if you are outside the 4G coverage, the call will be transferred to 2G or 3G network without any delay.
Faster call connection and better voice quality
If you use a VoLTE-capable phone that does not have VoLTE service activated, your phone will use 3G or 2G network and call initiation will take 5-7 seconds. With VoLTE, your phone will be able to connect almost immediately, thereby saving phone's battery and your time. VoLTE also enables much better voice quality.
Additionally, you will be able to use 4G internet during the call - for example, set up a mobile Wi-Fi hotspot and share your phone's data connection. The new technology also enables various future services, like call recording, intelligent caller ID, status, instant messaging, etc.
VoLTE calls cost as much as regular calls. Thus, there will be no additional charges for using the VoLTE service.
To use VoLTE, you will need a telephone that supports 4G calls or VoLTE supported telephone, which has the latest manufacturer’s software. The service will be activated automatically, you will also receive an SMS notification about the activation of the service. There is no need for a separate app to use the service.

The following roaming and some other services are affected by 4G/VoLTE calls:
Samsung Galaxy S7 / S7 EDGE and Microsoft Lumia 950 and 950XL: once you have activated VoLTE, call forwarding will be conducted both in your home network and in the case of roaming. If you have activated the VoLTE service, but are using a phone that does not support this service, you need to call the following number to activate direct call forwarding: 6119925 (Estonian menu) or 6119926 (Russian menu). Forwarding will not be possible on a phone that does not support 4G calls.
With VoLTE you will always hear knocking when you receive another call during an active call. However, with VoLTE the caller will not receive a notification that you're busy with another call.
VoLTE service uses a new voicemail service with a new voicemail greeting. Your old voicemail messages will be archived and can be accessed by calling 5096006. To call voicemail from abroad, dial 5096005.
Hallo internet calls do not work over VoLTE. If you are an active internet calls user, we recommend not activating the VoLTE service.
Service restrictions can be set by your carrier or yourself. Restrictions set by the carrier apply both in your home network and in roaming. With VoLTE service, restrictions set by you do not apply in roaming.

If you use TwinSIM together with VoLTE and outgoing calls are restricted for the main number (e.g. with the Balance Limit service), make sure your calls are forwarded to the main number in order to receive calls.
If VoLTE and TwinNumber are used together, TwinNumber's fax and data call services do not work.

Microsoft Lumia phones: Go to the phone's menu and check Settings > Regular and radio network > Mobile service and SIM-card > SIM-card settings > Advanced 4G LTE services – IMS registration.
