No Signal? No Problem: Why Satellite Phones Are Booming in 2025

In June 2025, T-Mobile began a nationwide beta of its “T-Satellite” service built on SpaceX Starlink technology, with a July 2025 rollout and plans to include it at no extra cost on high‑end plans and about $10/month for others. On June 19, 2025, Vodafone Idea and AST SpaceMobile announced a partnership to deliver 4G/5G access from space in India using AST’s BlueWalker 3 satellites to reach remote areas. The FCC Space Bureau accepted Globalstar’s petition in early June 2025 to launch a second‑generation LEO constellation called “C‑3” for direct‑to‑device services, with Apple owning about 20% of Globalstar and a 50‑satellite

Beyond Cell Coverage: The Ultimate 2025 Guide to Satellite Texting Services

In late 2022, Apple launched Emergency SOS via satellite on the iPhone 14 series, enabling two-way emergency texting via Globalstar satellites. As of iOS 17 and later, iPhone 14/15 users in supported regions can share their location and send basic non-emergency texts via satellite, with two years of free service after activation before a paid plan. Garmin’s inReach Mini 2 provides global two-way texting via the Iridium network, with plans from about $15/month to $65/month and devices typically priced around $350–$450. ZOLEO uses the Iridium network for global messaging, costs about $200 for the device, offers plans from roughly $20

Satellite Technologies FAQ

Sputnik 1, launched by the Soviet Union on October 4, 1957, was the first artificial satellite. Explorer 1 became the United States’ first satellite in 1958. As of 2025, there are roughly 11,000+ active satellites orbiting Earth, with tens of thousands of pieces of inactive satellites and debris. Geostationary satellites orbit about 35,786 km (22,236 miles) above the equator and stay fixed over one ground spot. Most satellites use solar panels with large arrays and rechargeable batteries to power their instruments and systems, including during eclipses. The first known accidental collision of two satellites occurred in 2009. Starlink is SpaceX’s

Where Satellite Phones Are Illegal?

Where Satellite Phones Are Illegal?

Bangladesh bans satellite phone use; possession can lead to arrest and imprisonment. North Korea prohibits all unauthorized communication devices, foreigners must surrender phones and privacy is not guaranteed, with detention possible. India restricts satellite phones to government‑approved Inmarsat devices, requiring a license (No Objection Certificate) from the Department of Telecommunications before bringing one in. China maintains a de facto ban on private sat phones, requiring registration for limited state use and has deployed jammers in some areas to block unapproved devices. Chad bans satellite phones under any circumstances, with Thuraya explicitly outlawed and Iridium sometimes tolerated. Myanmar (Burma) effectively bans
