How to Protect Your Data When Traveling With a Phone

Update and back up your phone before traveling, enable its lost-device tools, and take care with public Wi-Fi and USB charging connections.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Before you travel, update your phone, back up important data, set a strong screen lock, and turn on its locate, remote-lock, and erase tools. On the trip, keep the phone with you, verify public Wi-Fi details, and avoid connecting it to shared USB ports or computers you do not control. Extra precautions matter for sensitive work and higher-risk destinations.

Prepare your phone before departure

  1. Install updates. Update the phone’s operating system and apps before leaving. The U.S. Department of State recommends updating devices before travel in its Communicating While Abroad guidance, last updated May 8, 2026.
  2. Back up important information. Save contacts, photos, and other important data to a trusted cloud account or a computer you control. A backup helps you recover information; it does not prevent someone who has the phone from accessing it.
  3. Set a strong screen lock. Use a passcode that is difficult to guess. The Federal Trade Commission recommends at least six digits in its phone security guidance. Avoid using an easily guessed sequence or personal date.
  4. Enable lost-device controls. Turn on the phone maker’s locate, remote-lock, and erase features before the trip. Check that you know how to access the account or service needed to use them if the phone is missing.
  5. Plan connectivity and emergency access. Check whether your plan works at the destination and what roaming will cost. A local SIM or international eSIM may be an alternative; check destination-specific rules. Save emergency contacts in the phone and somewhere you can reach them without it.
  6. Set work-device rules in advance. If the phone contains sensitive work information, ask your employer what data may travel and which device controls are required.

Keep the phone physically secure

Keep the phone with you and avoid leaving it unattended in public places. The State Department advises travelers to protect devices from theft and enable tracking in its communication guidance. A screen lock and tracking feature help limit exposure or locate a missing device, but neither prevents the phone from being stolen.

Use public Wi-Fi with care, not panic

Public Wi-Fi is not automatically an open window into your data. The FTC’s February 2023 consumer guidance says public Wi-Fi is usually safe today because encryption is widespread on websites. Check for HTTPS (often shown with a lock icon) when using a website: it encrypts the connection between your phone and that site. It does not make a fraudulent site legitimate or protect a compromised phone.

CISA’s Cybersecurity While Traveling tip card takes a cautious approach: confirm the hotspot name and login process with venue staff, avoid sensitive activity such as banking on unfamiliar public networks where possible, and prefer mobile data or a personal hotspot when available. These recommendations are compatible: HTTPS reduces the risk of data interception on a network, while verifying the hotspot helps you avoid fake networks and login pages. For sensitive work, follow employer rules even if a site uses HTTPS.

A VPN is not established as necessary for every traveler. The State Department advises using trusted VPN or VoIP apps abroad in its Communicating While Abroad guidance. If you use one, choose a service you trust and check local rules and your employer’s requirements.

Avoid uncontrolled USB charging connections

Do not connect your phone to a public USB charging station or an unfamiliar computer. CISA warns that a USB connection may allow the connected device to interact with your phone in unexpected ways. Prefer your own wall charger and cable plugged into a standard outlet. If you must use a shared USB port, a charge-only USB adapter—sometimes called a USB data blocker—can prevent a data connection through that port; it is an optional precaution, not a complete security measure.

Respond quickly if the phone is lost or stolen

  1. Use the manufacturer’s locate service from another device to check its location, if available.
  2. Remote-lock the phone. If you believe it cannot be recovered or its data may be exposed, use the remote-erase option.
  3. Contact your mobile carrier to suspend the line or SIM and ask about replacement service.
  4. Change passwords for important accounts if you think someone could access them, and review account activity where available.
  5. Use the emergency contacts and alternate communication method you prepared before departure to reach people who need to know.

Take additional precautions for work or higher-risk travel

For business travel, discuss device and data safeguards with your employer before departure. The State Department’s Business Travel and Work Abroad guidance, last updated August 11, 2025, warns: “Don’t expect privacy on Wi-Fi provided by hotels, airplanes, internet cafes, or public spaces.” Follow workplace policy on what information to carry and which networks or apps to use. For higher-risk destinations, check current destination guidance and local restrictions; SIM rules, network conditions, and phone settings vary by country and platform.
