Mobile networks in the United States
Good to know in the United States
- Networks
Three big networks
AT&T, T-Mobile and Verizon run the national networks, and towns and cities are well covered.
- Outdoors
National parks
The National Park Service warns that cell service varies from park to park, can be patchy inside a single park, and can drop even where a carrier's map shows coverage. Some visitor centers offer free Wi-Fi, a good place to download maps before you head in.
- Alerts
Emergency alerts
Phones on US networks can receive Wireless Emergency Alerts from authorities in the area you're in. They're free, need no sign-up, and arrive with a distinctive sound, as Ready.gov explains.
- Emergencies911Police, fire or ambulance
Call, don't text: texting 911 only works in some areas, and Iowa's 911 guide notes that a phone in roaming status, as one on a travel eSIM often is, gets a bounce-back message instead.
