             Tele2 AB : Tele2 first in Europe with voice over 4G

Stockholm - Tele2 AB (Tele2), (NASDAQ OMX Stockholm Exchange: TEL2 A and TEL2
B) today announced that Tele2 is the first operator in Europe to have tested
voice over LTE (VoLTE) in the live Swedish Tele2 LTE network. The tests proved
much better voice experience in the IP based LTE network compared to 2G and 3G

The tests have been conducted in a fully end-to-end standards compliant manner
using technology from Mavenir Systems and Nokia Siemens Networks implemented
in the live LTE network in Sweden.

VoLTE technology improves voice quality significantly and enables much faster
call setup times.

Joachim Horn, CTIO Tele2 AB, commented: "We have consciously built in support
for VoLTE in the 4G network, covering almost the entire population of Sweden.
The tests we have conducted have shown tremendous results in a multi-vendor
environment. From a technical standpoint we could be ready to launch
commercially within a year."

VoLTE is the next generation technology for transporting voice traffic as an
IP data stream in LTE. Today the LTE networks are solely used for data traffic
whilst voice traffic is still handled in the 2G and 3G networks. By moving and
converting the voice traffic to LTE data, the opportunities for a superior and
seamless user experience of voice integrated in new LTE services and
applications are increasing.

Joachim Horn continued: "Not only does VoLTE enable superior voice and data
experience simultaneously for our customers, but the technology is also more
cost efficient".
