Some of the newest features for the iPhone and the Google Pixel 9 could be lifesavers in the wake of a natural disaster

The Apple iPhone 14, 15, and 16 (when updated to iOS 18) and all models of the Google Pixel 9 have SOS features that let users contact emergency services even when Wi-Fi and cell service are unavailable. Additionally, those iPhone models have a Messaging Via Satellite feature that enables texting without Wi-Fi or cell service.

For these services to work, you need to be outside with a clear view of the sky and horizon. This won't work if you're in the thick of a storm, as these features are intended for when the sky has cleared but cellular service and Wi-Fi are down.

These services are pre-installed on a Google Pixel 9, but if you're using an iPhone 14, 15, or 16, you'll need to make sure your phone is running iOS 18 to access them. It is also a good idea to fill out your Medical ID and emergency contacts on your iPhone and your emergency contacts on your Pixel. Once you're done with all that, here's how to start sending messages via satellite.

Emergency SOS

For Apple's Emergency SOS Via Satellite, call 911. If it doesn't connect, you should see "Emergency Text via Satellite" on your screen. Tap that, then tap Report Emergency and answer the onscreen instructions. You will then be connected to a text conversation with emergency responders.

For Google's Satellite SOS on the Pixel 9, dial 911. If it does not connect, you'll see Satellite SOS onscreen. Tap Satellite SOS >  Use Satellite SOS > Start. Answer the onscreen questions and prompts, and if everything works as intended, you'll be connected to a text conversation with emergency responders.

iPhone Messaging Via Satellite

Messaging Via Satellite is available for the iPhone 14, 15, and 16 with iOS 18. This allows you to send texts to friends and family when Wi-Fi and cellular services are not available.

In order for you to receive a satellite message from someone (without having initiated contact), that person needs to either be in your emergency contacts or added as a member of your Family Sharing Group. To make sure that your friends and family can message you when you’re without service, add your most important contacts to your Family Sharing Group. To do this, go to Settings > [Your Name] > Family (or Family Sharing) > Set Up Your Family and follow the onscreen instructions. If you already have Family Sharing set up and want to add new people, go to Settings > Family > Add Member.

Encourage your contacts to update their phones, too. For them to receive your iMessages via satellite, they have to have iOS 18 or later, and for them to reply to SMS messages that you send via satellite, they need to have iOS 17.6 or later—or a non-Apple device.

To send an iMessage via satellite, open Messages. If you're without service, you should get a message about satellite service. Tap Use Messages via Satellite and follow the onscreen instructions. When you are prompted, enter your message and hit Send.

To send an SMS, go to Settings > Apps > Messages and turn on Send as Text Message. Then go to Messages; if you're without service, you should get a message about satellite service. Tap Use Messages via Satellite and follow the onscreen instructions. When you are prompted, enter your message and hit Send.

My Experience

My title is Senior Features Writer, which is a license to write about absolutely anything if I can connect it to technology (I can). I’ve been at PCMag since 2011 and have covered the surveillance state, vaccination cards, ghost guns, voting, ISIS, art, fashion, film, design, gender bias, and more. You might have seen me on TV talking about these topics or heard me on your commute home on the radio or a podcast. Or maybe you’ve just seen my Bernie meme

I strive to explain topics that you might come across in the news but not fully understand, such as NFTs and meme stocks. I’ve had the pleasure of talking tech with Jeff Goldblum, Ang Lee, and other celebrities who have brought a different perspective to it. I put great care into writing gift guides and am always touched by the notes I get from people who’ve used them to choose presents that have been well-received. Though I love that I get to write about the tech industry every day, it’s touched by gender, racial, and socioeconomic inequality and I try to bring these topics to light. 

Outside of PCMag, I write fiction, poetry, humor, and essays on culture.

My Areas of Expertise

  • Making incomprehensible tech news easy to understand
  • Expanding the boundaries of topics covered in the industry
  • Figuring out tips and tricks in apps and on devices and letting you know about them
  • Putting together gift guides for everyone in your life 

The Technology I Use

All that gadgets is gold for me: my iPhone 11 Pro, my fifth-generation iPad that I use only for streaming videos and music, my iPad mini 4 that I like to take with me whenever I carry a bag that can fit it, and my MacBook Pro. Why are they all different shades of gold, though? What’s going on, Apple? 

None of them quite live up to my two past loves: my LG Lotus LX600 phone and my Sony Walkman NW-E005 MP3 player. 

I've never given up wired earbuds so I was ahead of all those trend pieces. I use a Mangotek Lightning-to-3.5mm headphone jack adapter to connect them to my phone. 

I have had so many ebook readers, but I prefer paper to them all. Still, my Kindle Paperwhite is perfect for traveling or when I’m too impatient to wait for a book to be released in paperback.
