Why 911 can’t always find you when you call from a cell phone
Uber can find your front door, but for years, 23 million 911 calls annually went to the wrong dispatch center. A federal fix just kicked in, but it still has holes. Here are the phone settings that close them.
⚡ TL;DR
- For decades, 911 routed your cell call by the nearest tower, sending an estimated 23 million calls a year to the wrong dispatch center.
- A federal fix finished rolling out in May, but calls still fall back to a tower guessing when your phone can’t get a fast location fix.
- Three minutes of settings changes on iPhone, Samsung or Pixel make sure 911 sees your real location.

Uber finds your driveway. DoorDash finds your porch light. Dial 911, and the dispatcher might see nothing but a guess from the nearest cell tower.
📞 Why 911 is stuck in the landline era
The 911 network was built for landlines, back when your phone number was your address. Not anymore. Almost every 911 call now comes from a cell phone. And for decades, wireless calls got routed by the tower they pinged, not by you. That tower can sit in the next county. So can the dispatcher who picks up.
How bad was the problem? Before regulators stepped in, the National Emergency Number Association estimated 23 million wireless 911 calls a year landed at the wrong dispatch center. The FCC figured better location could save 10,000 lives a year. Ten thousand.
In 2015, Shanell Anderson’s SUV slid into a Georgia pond. She stayed calm and told 911 her cross streets six times. But her call hit a tower in the next county, and that dispatcher’s map didn’t show her streets. Rescuers took 20 minutes. She didn’t survive.
✅ The good news and the catch
The FCC now requires carriers to route your 911 call by your phone’s actual location, not whatever tower it hit. Big carriers switched over in late 2024. Smaller ones came online this past May.
The catch? When your phone can’t grab a fast fix (basements, concrete high-rises, rural valleys with no bars), your call still falls back to the old tower method. Millions a year still will. Your settings decide whether 911 sees you or a guess two towns over.
🚑 Lock it down
I tested these myself, but phone makers love moving things around, so your taps may look a little different. Poke around. The setting’s in there.
- iPhone: Settings > Privacy & Security > Location Services > System Services, turn on Emergency Calls & SOS. Then in Health, tap your photo > Medical ID and turn on Share During Emergency Call.
- Android: Settings > Safety & emergency > Emergency Location Service.
Use Wi-Fi calling? Your carrier keeps an emergency address on file. Moved since? 911 could get your OLD address.
- iPhone: Settings > Cellular > Wi-Fi Calling > Update Emergency Address.
- Samsung: Settings > Connections > Wi-Fi Calling > menu > Emergency address.
- Pixel: Settings > Network & internet > SIMs > your carrier > Wi-Fi calling > Emergency address.
- On any other Android or if you can’t find the setting: Open your carrier’s app (Verizon, T-Mobile, AT&T, etc.), search “Wi-Fi calling emergency address” and update it there. Same fix, different door.
📩 Send this to anyone who only carries a cell phone. It’s their lifeline to 911.
