Ukraine's largest mobile operator Kyivstar has successfully conducted the first field test of Elon Musk's Starlink direct-to-cell satellite technology in Eastern Europe, the company said on Tuesday, Reuters reports.

The pilot test took place in the Zhytomyr region using Starlink's direct-to-cell technology, Kyivstar said, with its CEO Oleksandr Komarov and Ukraine's digital transformation minister Mykhailo Fedorov exchanging messages via regular smartphones.

Direct-to-cell satellite technology aims to provide reliable connectivity when terrestrial networks are unavailable, a critical asset for war-torn Ukraine where Russian attacks on infrastructure regularly disrupt communications.

Satellites used for this service are equipped with advanced cellular modems that function like cell towers in space, beaming signals directly to smartphones on the ground.

Space X-owned Starlink has signed deals with telcos in 10 countries for a direct-to-cell service, with Kyivstar set to become the first operator in Europe to roll it out.

Kyivstar and Starlink plan to commercially launch direct-to-cell connectivity in the fourth quarter of 2025, starting with messaging services.

Mobile satellite broadband data is planned to be made available to a wider audience at the beginning of 2026, Komarov told Reuters in July.

VEON, which owns Kyivstar, is also in talks with other providers, including Amazon's Project Kuiper, to expand its satellite services for mobile devices beyond Ukraine.
