If a power shutoff leaves your phone without service, conserve its charge, follow official local instructions, and switch to a communication plan that does not depend on a working network. A charged phone cannot connect when the cellular network is unavailable, and a working home router cannot help if its internet connection or power fails. Prepare contacts, meeting plans, and backup charging before an outage begins.
What a power shutoff can—and cannot—tell you about connectivity
A public safety power shutoff (PSPS) is an intentional electricity shutoff used to reduce wildfire risk. Other outages may be unplanned, but both can disrupt communications. The U.S. Environmental Protection Agency’s PSPS Standard Operating Procedure Template, updated May 28, 2026, addresses planning, notification, loss of power, extended outages, and restoration; the agency notes that much of the guidance applies to outages generally.

Electricity, broadband, landline voice, and cellular service are separate systems. A household outage does not prove that mobile service has failed, and a powered phone does not prove that a network is available. Depending on the incident, provider backup power, network equipment, or physical infrastructure may be affected. Conditions differ by location and provider, so do not treat any device or service as a guaranteed connection.

Before the shutoff: prepare a plan that works offline
Check official notices and directions
Follow notices from your electric utility and local emergency management agency. Confirm the expected shutoff time and duration if provided, and note any evacuation directions, assistance locations, and official alert channels. Conditions can change; check for updates while service is still available. The EPA template treats communication and coordination as part of PSPS planning and recovery.

Save essential information where you can reach it without internet
- Write down key phone numbers, addresses, household meeting points, and relevant instructions, or save them on your device for offline access.
- Agree on a check-in plan and an out-of-area or nearby contact if useful. Set a meeting place that does not rely on an app or live location sharing.
- Know where to go for local updates or assistance if electronic channels stop working; use the locations and directions named by local authorities.
Charge devices and identify compatible backup power
Charge phones, tablets, and backup batteries before the shutoff. Decide which device is most important for calls and messages, and reduce nonessential use if service becomes unreliable. FEMA’s 2017 Power Outage Incident Annex identifies vehicle batteries, solar chargers, and hand-crank devices as possible ways to recharge or provide power. Check that any charger is compatible with your device and that you can use it safely; sunlight, vehicle access, and equipment availability are not assured.
CDC preparedness guidance also recommends identifying backup power for personal devices and medical equipment. Arrange a separate plan for essential medical devices with your care team, equipment provider, and local emergency resources; do not assume a phone power bank can operate medical equipment.

During the outage: use power carefully and avoid relying on one channel
Preserve phone charge
Lower screen brightness, limit background activity, and avoid nonessential use. Keep the phone available for important calls and messages. These are practical conservation steps, not a tested runtime guarantee: battery life varies by device, age, signal conditions, and use.
FEMA’s 2017 annex gives a general estimate of five to eight hours for a typical smart-device battery charge. That dated estimate is not a forecast for a modern phone or for your device. FEMA also describes a scenario without significant infrastructure damage in which Emergency Alert System and IPAWS dissemination is most effective in the initial four-to-eight-hour window after power loss, with communication potentially degrading later as device batteries run down. Those figures describe the annex’s scenario, not a universal service window or guarantee of alerts.

If calls do not connect
You can try a text message when a voice call does not complete, but texts are not guaranteed: congestion or complete network loss can prevent both. Do not spend critical battery or delay taking necessary emergency action by repeatedly retrying a failed connection. Follow official directions and use your offline plan or locally available assistance.
Internet-based calling, including interconnected VoIP, depends on an operating internet connection and the power needed by customer equipment. The FCC’s 2026 order excerpt describes those conditions and notes that physical infrastructure can also be damaged. If the connection or required powered equipment fails, internet-based calling may stop.

FCC Order FCC 15-98 (2015) concerns access to 911 through a defined category of facilities-based fixed residential voice service that is not line-powered. It describes provider offers of at least eight hours of standby backup and, within three years, an option for at least 24 hours. This is a service-specific rule, not a guarantee that household internet, cellular service, every home phone, or 911 access will work during an outage. Check with your provider about the service and equipment at your address.

Follow safety instructions
Use utility and local-government safety directions. Do not approach downed power lines or damaged utility equipment; report hazards through the official channels available to you. If authorities direct an evacuation, follow that direction rather than waiting for internet or cellular service to return.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.After household power returns
Keep checking utility and local authority notices. Restored electricity at home does not establish that cellular or broadband service has recovered. Confirm that essential communications and medical equipment are operating before relying on them, and follow provider or equipment-maker guidance if backup devices need attention.
