What You Need to Know About Satellite Connectivity in Phones

As carriers begin to unveil their own satellite plans, here’s everything you need to know whether your phone supports satellite connectivity or is “satellite optimized.”

When you hear the words “satellite phone,” your mind probably conjures up an image of a clunky mobile monstrosity straight out of a spy thriller. Usually rather bulky and utilitarian, traditional satellite phones are typically required in remote locations where cellular networks are unavailable. Nowadays, however, satellite connectivity can be found in regular smartphones too, thanks to new hardware innovations and unique partnerships with satellite network providers.

They can’t fully replace traditional satellite phones, but in an emergency situation, this feature can be a real lifesaver. This kind of connectivity has already proven useful in rescuing people from Hurricanes Milton and Helene, the recent wildfires in Los Angeles and the deadly fires in Maui. There are also several reported cases of the Emergency SOS texting feature rescuing lost hikers. While satellite connectivity isn’t in every phone right now, it’s clear that there’s a real need for it, and don’t be surprised to see even more of this feature in years to come.

What is satellite connectivity in phones?

If a phone has satellite connectivity, it can connect to a satellite when you don’t have a cellular signal. This feature debuted in Apple’s iPhone 14 in 2022 and has since been incorporated in subsequent iPhones as well as certain Android phones like Google’s Pixel 9 and Samsung’s Galaxy S25. Some phones have satellite connectivity regardless of carrier for a period of time (like recent iPhones and the Pixel 9), while others require a specific carrier due to partnerships and hardware compatibility (like Galaxy S25 phones on Verizon).

Apple provides satellite connectivity in partnership with Globalstar, its affiliates and third-party network providers. However, Apple doesn’t provide satellite connectivity in models purchased in Armenia, Belarus, China, Hong Kong, Macao, Kazakhstan or Russia. Google partnered with Skylo for its satellite service, which currently works only in the continental US and on Pixel 9 devices.

Several US carriers have also recently started to provide satellite connectivity. Verizon, for example, has partnered with Skylo to provide its satellite messaging service to specific satellite-enabled phones like the Galaxy S25 and the Pixel 9 series. T-Mobile, on the other hand, has partnered with SpaceX’s Starlink, which uses a “direct-to-cell” technology that doesn’t require the phone to have a specialized satellite modem.

Regardless of the kind of satellite connectivity your phone has, it still needs one important thing to work properly: connection with a satellite. Not only are these satellites hundreds of miles away in space, but they also orbit the Earth at a quick pace. You definitely need to be outside for the best satellite connection possible. You also want a direct view of the sky and to be away from tall trees or heavy foliage. Even then, a message might take 30 seconds or more to send depending on the rest of your surroundings, the length of the message and the status of the satellite network.

How can I use satellite connectivity?

The most obvious benefit of satellite connectivity in phones is SOS messaging. Apple calls its service Emergency SOS, while Google calls its service Satellite SOS. Like the names suggest, these services let you contact an emergency dispatcher when you have no phone signal. Apple also added other related satellite connectivity features to its iPhones, such as Roadside Assistance via satellite and Send Location via satellite (via the Find My feature).

In 2024, Apple added a Messages via satellite feature to iOS 18 that allows iMessages or SMS messages to be sent and received by satellite to anyone, not just emergency services. It supports emoji, tapbacks, and iMessage bubbles and screen effects, but you can’t send or receive photos or videos, and it doesn’t support group chats. The recipient must also have iOS 18 or newer to receive iMessages (replying to an SMS message via satellite requires iOS 17.6 or later or a non-Apple phone). This works no matter which carrier you use for your phone.

Verizon customers who have either a Galaxy S25 or a Pixel 9 handset can send and receive text messages via satellite to any device, along with SOS emergency services. Those who use T-Mobile’s Starlink service, called T-Satellite, can send and receive messages to anyone as well. Right now, picture messaging, voice calls and data aren’t supported, but T-Mobile plans to add them soon.

One especially interesting aspect of T-Satellite, is that it’s open not just to T-Mobile customers but those from other carriers as well. The service is free for now during its beta trial period, but once the full service launches in July, and will remain free for T-Mobile customers on Go5G Next or Experience More plans. Otherwise, T-Satellite is $10 a month for T-Mobile customers on other plans, as well as for Verizon and AT&T customers.

As of this writing, Verizon is offering its satellite messaging service for free. Apple and Google have both said they’ll provide their respective satellite services for free for the first two years. It’s unclear what happens after that, but Apple has previously extended satellite service for iPhone 14 owners.

How do I know if my phone has satellite connectivity?

As of this writing, only certain phones come with built-in satellite connectivity. In the US this includes the iPhone 14 and newer, the Pixel 9 series as well as the Galaxy S25. The recent iPhones and the Pixel 9 series can connect to satellites when you lose your connection to a cellular network, while the Galaxy S25 requires a carrier like Verizon. The Pixel 9 can also use Verizon’s satellite service. These phones come with specialized hardware and satellite modems that enable satellite connectivity right off the bat.

Thanks to T-Mobile’s partnership with Starlink, however, more phones could have satellite connectivity even on existing hardware. T-Mobile’s Starlink satellite service (also known as T-Satellite) is currently compatible with “satellite optimized” phones such as the iPhone 14 and newer, the Pixel 9 series, the Motorola Razr Plus 2024, the Galaxy S24 and newer, the Galaxy A36 series, the Galaxy Z Flip 6 and the Galaxy Z Fold 6. In this instance, “satellite optimization” simply means being able to seamlessly connect with a satellite in the absence of a cellular network.

You’ll know your phone has satellite connectivity if you can find the “Satellite” option in Settings or Control Center, usually when you’re out of Wi-Fi or cellular network coverage. There’ll often be a satellite icon or “SAT” symbol where the cellular symbol would be.

Can I use satellite connectivity while having a cellular signal?

No, you generally can’t have satellite and cellular connectivity at the same time. Satellite connectivity is designed to be used as a fallback when Wi-Fi or cellular networks are not available.

What are the limitations of satellite connectivity?

At the moment, satellite connectivity is limited to text messaging, with no support for multimedia, voice calls or data. As mentioned earlier, there are also potential physical restrictions to contend with. If you’re indoors or under heavy foliage or you don’t have a clear line of sight of the sky, satellite connectivity could be an issue. There is also a lack of coverage in the water off the coasts.

Update, May 7: T-Satellite is free for T-Mobile customers on Go5G Next or Experience More plans and is $10 per month for other users on other T-Mobile plans and for Verizon and AT&T subscribers.

Trump Maintains US‑Iran Negotiations Continue Amid Tehran’s Denials of Duplicity

President Trump insists that US‑Iran talks are ongoing despite Tehran’s denial of any negotiation plans, while warning that only a deal or total surrender will allow passage through the Strait of Hormuz. Conflicting statements from both sides have heightened uncertainty as the conflict enters its sixth month.

On Monday, President Donald Trump asserted that negotiations between the United States and Iran are still taking place, even after Tehran stated it has no intention of engaging in direct talks with Washington.

In a fiery Truth Social post, Trump labeled Iran’s leaders “unbelievably duplicitous,” claiming they are lying about ongoing peace talks “whether Iran wants to admit it or not.” He repeated his assertion that the United States completely controls the Strait of Hormuz, despite maritime traffic through the crucial route lingering at only a small fraction of pre‑conflict levels.

He wrote, “Nothing reaches Iran unless we allow it, and nothing will pass unless a deal—or total surrender—is achieved.”

Earlier that day, Iranian Foreign Ministry spokesperson Esmail Baghaei told reporters there is no imminent plan for U.S.–Iran negotiations, contradicting Trump’s earlier comment that talks would resume Monday afternoon. Baghaei added that Iran’s only current discussions are with Oman concerning the Strait of Hormuz.

The conflicting statements have heightened uncertainty over the peace‑talk process and the broader conflict, now in its sixth month.

Trump’s assertion about new negotiations came a day after he said on Truth Social that he had agreed to cancel a massive strike against Iran “subject to being able to rapidly make a DEAL.” He said in the same post that Iran and other Middle Eastern countries had asked him to hold off on that attack because “the perimeters of a deal has been agreed to.”

Trump has claimed dozens of times throughout the more‑than‑five‑month‑long war that a deal is at hand. No permanent deal has been signed, and a temporary ceasefire reached in June has fallen apart.

Trump has also repeatedly threatened to launch devastating strikes against Iran before backing off. After the latest example, oil prices on Monday fell and stocks surged.

BMI, a research unit of Fitch Solutions, said in a note Monday that a broader diplomatic understanding on reopening the Strait of Hormuz is still achievable this quarter, while raising the probability of its escalation scenario to 35% from 25%, citing mounting military, diplomatic and economic signs of rising U.S.-Iran tensions.

“Diplomatic progress is likely to be punctuated by periodic military flare-ups, while miscalculation by either side could trigger a renewed escalation,” BMI analysts wrote in a note. The firm said the key issue to watch is the future governance of the strait, as the Iran-Oman talks — potentially backed by Gulf states, China and the U.S. — point to efforts to build a post-conflict shipping framework.

Shipping risks persist even as diplomacy appears to be advancing. The United Kingdom Maritime Trade Operations Centre said it received a report of an incident 20 nautical miles (23 miles) northeast of Khasab, Oman — at the mouth of the strait — with a tanker’s master reporting an explosion in close proximity to the vessel at about 20:37 UTC Sunday (4:37 pm ET). The vessel and crew were safe and authorities are investigating, UKMTO said, advising ships to transit with caution.

The proposal Trump announced over the weekend calls for the U.S. and Iran to return to negotiations and continue ironing out some of the thorny issues that had derailed diplomatic efforts, according to The Associated Press, citing a regional official involved in the mediation efforts.

The official said the proposal also includes a reopening of the Hormuz Strait and halting attacks across the region, including by Iranian-backed militias in Iraq on the Arab Gulf countries and Jordan.

The U.S., for its part, will end its naval blockade on Iran and allow Tehran to export its oil, the official said, adding that no deal has been reached, although the mediation efforts remained underway.

Trump’s weekend reversal has lowered the temperature after days of escalating attacks across the Gulf. Kuwait said Saturday that Iranian forces launched a wave of drones within its airspace, with its military destroying multiple aircraft after Iran targeted critical infrastructure in the country’s north.

A parallel track with Muscat is also advancing. Iranian diplomats said Tehran was close to reaching a new arrangement with Oman to manage shipping through the Strait of Hormuz, a deal critical to preventing the war from escalating further, according to the Financial Times.

Iranian officials said negotiations over future management of the Hormuz Strait with Oman, which sits on the opposite shore of the waterway, are in their final stages. The agreed shipping route would be different from those used before, according to Iran’s Foreign Ministry spokesperson, Baghaei, adding that the new route was separate from the issue of the strait’s reopening or continued closure.

Oil Prices Slide as Trump Halts Planned Iran Strike

Oil prices dropped after Trump cancelled a planned strike on Iran, with WTI down about 5% and Brent near 5% lower. He said the move followed requests from Tehran and regional allies for a pause while a deal shaping the Strait of Hormuz and Iran’s nuclear program is negotiated.

Oil prices fell on Monday after President Donald Trump announced he had cancelled a planned strike on Iran. WTI futures dropped roughly 5% to $80.34 a barrel, while Brent slipped about 4.7% to $83.77 a barrel.

Trump said early Sunday he called off the strike after Iran and several Middle Eastern nations asked him to hold off, noting that the outlines of a deal had been agreed upon. He added that the prospective accord would entail the immediate, full opening of the Strait of Hormuz and an end to Iran’s nuclear ambitions, according to his Truth Social post.

The president had been considering another round of strikes as diplomatic hopes waned since the conflict began on February 28. He said the U.S. and Iran would meet for talks on Monday, but Iran denied any scheduled negotiations with Washington, citing PressTV. Iran’s foreign‑ministry spokesperson Esmaeil Baghaei clarified that Tehran was only discussing shipping routes through the Strait of Hormuz with Oman. In a follow‑up Truth Social message, Trump insisted that, regardless of Iran’s acknowledgment, the United States is indeed discussing a solution to a long‑standing problem created by Iran.

Oil Prices Drop as Trump Cancels Planned Attack on Iran

Oil prices fell sharply after President Trump announced the cancellation of a planned strike on Iran, citing a new deal that would open the Hormuz Strait and end Iran’s nuclear threat.

Oil prices fell sharply on Monday after President Donald Trump announced that he had called off a planned strike on Iran.

West Texas Intermediate futures, the U.S. benchmark, slipped roughly 5% to close at $80.34 per barrel, while Brent crude, the international benchmark, declined 4.7% to settle at $83.77 a barrel.

Trump made the announcement early Sunday, saying he had canceled the strike following requests from Tehran and other Middle Eastern countries.

In a Truth Social post, he wrote: “We have just been asked by Iran, and other Middle Eastern Countries, to hold off any attack in that the perimeters of a deal has been agreed to.”

The president indicated that the proposed agreement would include the immediate, complete, and total opening of the Hormuz Strait, as well as an end to Iran’s nuclear threat.

Trump had been weighing additional strikes amid diminishing prospects for a diplomatic resolution to the conflict that began on Feb. 28. He stated that the U.S. and Iran would hold negotiations on Monday.

Tehran denied that talks were planned with Washington, according to state news outlet PressTV.

Iran’s Foreign Ministry spokesman Esmaeil Baghaei said Tehran was only holding talks with Oman regarding the routes ships can use through the Strait of Hormuz.

In a subsequent Truth Social post, Trump added that whether “Iran wants to admit it or not, we are, in fact, talking of a solution to a problem that they have caused for decades.”
