4G & 4.5G
LTE technology (Long Term Evolution), launched in December 2015 by Telenor Bulgaria (and now operated by CETIN), represents the fourth generation of mobile networks (4G) and provides customers with a unique experience in using the services which demand high speeds of data transfer, as well as faster access to applications, such as streaming of high-definition video content (Youtube, streaming, mobile TV, etc.) music streaming, uploading and downloading files, photos and other content.
LTE-Advanced supporting network is a combination of various network features and functionalities, which enable enhanced user experience. The 4.5G Network offers increased data transfer speeds through aggregation of multiple LTE carriers allowing customers with applicable handsets to benefit from increased utilization of available network resources.
VoLTE is voice call technology that was launched on the 4G/LTE network in 2018 by Telenor Bulgaria. With VoLTE you can speak through 4G, while continuing to browse on the 4G network and at the same time benefit from improved HD quality of the voice call, quicker connectivity and a longer battery life.
Introduced in 2019 by Telenor Bulgaria, ViLTE is an extension of VoLTE technology that enables video calling over a 4G network on supported devices. It allows high quality video calls, provides full security of SIM based authentication but does not require additional registration or special application.
CETIN Bulgaria is actively preparing for the introduction of 5G to Bulgaria, and while there is no concrete date yet set, it is confident that it will manage the roll-out of 5G effectively and efficiently.
