Starlink Mobile launches in Japan
Starlink Mobile went live for SoftBank customers in Japan, offering voice and video calls plus texting via satellite without extra fees and extending direct‑to‑cell satellite connectivity in a major market. The launch represents another step toward carrier partnerships that let satellite services plug into standard mobile experiences. (x.com)
SoftBank began offering “SoftBank Starlink Direct” in Japan on April 10, letting compatible phones connect straight to SpaceX satellites when ground coverage drops out. (softbank.jp) The service launched on SoftBank, Y!mobile and LINEMO, with no application required at launch for SoftBank smartphone plans and Y!mobile’s Simple, Simple 2 and Simple 3 plans. SoftBank said other Y!mobile plans and LINEMO customers can use it without extra charge through the end of June 2026, with a 1,650 yen monthly option planned from July 2026. (softbank.jp) SoftBank said the link works only in Japan, outdoors, when a user cannot receive SoftBank 5G, 4G Long-Term Evolution, or 4G service and has a clear view of the sky. The company said the service supports text messages, some emergency alerts and limited data on selected apps, but not ordinary voice calls or emergency calling. (softbank.jp) Satellite-to-phone service is built for the gaps between cell towers: mountains, remote islands, offshore waters and disaster zones where ground equipment is damaged. SoftBank said those are the places it is targeting first with the Starlink link. (softbank.jp) Japan’s carriers have been racing to add that backup layer. NTT Docomo said on April 2 that it will start its own “docomo Starlink Direct” service on April 27, after KDDI had already moved earlier into satellite messaging. (docomo.ne.jp) (jakotaindex.com) SoftBank’s version starts with messaging and app data rather than turning a satellite link into a normal mobile line. The company said LINE text chats and location sharing would work, but LINE stickers, images, video, voice calls and video calls would not. (softbank.jp) SoftBank also said PayPay, Yahoo! JAPAN and other group apps are scheduled to roll out on the service starting April 13. The company warned speeds can be slower than terrestrial mobile networks and connections can pause when a phone switches between satellites. (softbank.jp) The rollout follows SoftBank’s April 2 announcement that it would provide direct satellite-to-smartphone service using Starlink, with launch timing to be announced later. Eight days later, the service went live.
