Security Precautions to Take While Traveling

/in /by

When we think about digital and device security, we mostly think about the fixed locations where people spend most of their time—home, school, and work. But what about when you’re traveling? Some security concerns remain the same when you’re on the road, but new ones crop up.

We’ll assume that you already keep your devices up to date, use FileVault on Macs, have at least a six-digit iOS passcode, have strong password habits, and use multi-factor authentication wherever possible. Other options are more specific to travel.

As with our more general article about increasing security last month, we’ve divided our list of suggestions into two parts: things that everyone should do and measures that only people who worry about being specifically targeted should employ.

Sensible Travel Security Precautions for Everyone

These suggestions are appropriate for everyone who travels, and they’re aimed primarily at avoiding relatively common problems: loss, theft, data loss, and generalized snooping:

  • Focus on physical security: As a tourist, you may be targeted by thieves, so it’s important to keep your iPhone in a secure pocket whenever you’re not using it. Carry an iPad or laptop in a bag that can’t be snatched, or leave them locked or at least concealed in your hotel room.
  • Enable Find My for all your devices: You should have already done this, but if not, enable Find My to improve your chances of finding a device you lose or accidentally leave behind. It might help if the device is stolen, but local police cooperation for recovering stolen items can vary widely. Don’t attempt to recover a stolen device yourself.
  • Put AirTags in your luggage and laptop bags: AirTags can help you track down lost luggage—you can now share their locations with airlines—and prevent you from accidentally leaving bags behind. An AirTag may also help with locating a stolen item, but always work with local law enforcement.
  • Enable biometric authentication and Stolen Device Protection: Using Face ID or Touch ID wherever possible and having Stolen Device Protection enabled on your iPhone in Settings > Face/Touch ID & Passcode is even more important when traveling.
  • Use a VPN or iCloud Private Relay: Because you may be using Wi-Fi networks whose security you know nothing about, it’s best to use a VPN like Mullvad VPN, NordVPN, or ProtonVPN to encrypt all your traffic. At a minimum, use iCloud Private Relay, which requires an iCloud+ subscription and won’t encrypt traffic from most non-Apple apps.
  • Use iCloud Photos or another backup option: To ensure you don’t lose precious vacation photos, use iCloud Photos so all your photos are uploaded to the cloud whenever you have access. This will almost certainly require an iCloud+ subscription for sufficient storage space. If Wi-Fi and cellular are too slow or unavailable, consider an external SSD to which you can manually export photos and videos for backup. To speed up the process, you could create a shortcut that automatically copies all photos taken that day.
  • Use iCloud Backup: It’s best to use iCloud Backup to back up your entire iPhone every night. That way, if your iPhone is lost or destroyed, you may be able to buy a replacement and restore from backup in relatively little time. You will probably need an iCloud+ subscription to have enough backup space.
  • Practice dealing with a lost or stolen device: If the worst happens and you lose one of your devices while traveling, you need to know what to do. Immediately go to Find My on another device or iCloud.com and mark the device as lost. If there’s a chance of getting it back, stop there. However, if you believe the device was stolen, your data is at risk, and tracking it is no longer useful, use Erase This Device in Find My to wipe it. Activation Lock will remain enabled to prevent anyone from reusing the device.

Increasing Travel Security for People Who May Be Targeted

Not all travel is fondue and gamelans. If you’re a journalist, activist, government employee, or corporate executive with access to sensitive data, you could be a target while traveling. This is particularly true if you are headed to countries like China, Russia, or others with authoritarian governments and powerful intelligence agencies. Along with the suggestions above, we recommend:

  • Be aware of local laws and government practices: It’s important to read up on regional laws regarding data access and potential government capabilities at your destination. Knowing what to expect can help you reduce your risks and take appropriate precautions.
  • Use caution with cellular access: Even if your carrier allows roaming, consider using a dedicated eSIM for international travel, separate from your personal one. That way, you can use local cellular networks without revealing your home number. Be aware that your traffic may be monitored.
  • Enable Lockdown Mode: If you’re concerned about your iPhone or iPad being targeted by local law enforcement or government intelligence agencies, turn on Lockdown Mode in Settings > Privacy & Security > Lockdown Mode. To increase security, it blocks most attachment types in Messages, complex Web technologies, incoming FaceTime calls from unknown callers, non-secure Wi-Fi network connections, and incoming invitations to Apple services. Plus, it excludes location information from shared photos, requires approval to connect accessories, and more.
  • Reduce and protect your use of cloud services: While using a VPN is essential, you should still avoid using cloud services much if government entities might have access to stored files. If you need to upload files, encrypt them first using the free and open-source Cryptomator.
  • Know how to disable Face ID and Touch ID: If you find yourself in a situation where you believe you may be compelled to unlock your iPhone or iPad with your face or fingerprint, press and hold the side or top button and either volume button to display the power off slider. This temporarily disables biometric authentication, requiring your passcode for the next unlock.
  • Use dedicated travel devices and accounts: If you’re traveling to a potentially hostile part of the world, we strongly recommend carrying only devices—preferably iPhones or iPads, which are more secure than Macs—configured to contain none of your personal data or regular accounts. Keep them with you at all times, assume they could be confiscated, and be aware you might be compelled to share passcodes or other account information. Create a separate Apple Account for such devices.

Best of luck in your travels! With just a little preparation, you can reduce the chances that something bad will happen during a vacation. If you’re traveling on business to somewhere more concerning, putting in additional effort could prevent truly problematic things from happening.

Social Media: Security at home is one thing, but what about when you’re on the road? Many of the same precautions apply, but depending on your level of concern and where you’re going, additional techniques can help keep you and your data safe.

Apple Is Driving the iPhone to eSIM: Here’s What You Need to Know

/in /by

Perhaps the most surprising change in the iPhone 14 line, at least in the United States, was the shift from using removable SIM cards to eSIM.

SIM cards—SIM stands for Subscriber Identity Module—have been a fixture in the mobile phone world for many years because they provide the unique identification necessary to connect a subscriber and a plan with a phone. Because SIM cards are removable, you can use them to transfer an existing plan to a new phone, switch carriers, or enable temporary service while traveling—all by inserting the appropriate SIM card.

But SIM cards are small, fussy, and require physical interaction, so the industry came up with eSIM, or embedded SIM, where a programmable SIM is integrated into the circuitry of the phone. With eSIM, you can also activate a plan, transfer a plan to a new phone, or change carriers, typically without interacting with customer service. You also don’t have to acquire a physical SIM, figure out how to open your phone’s SIM tray, or insert the tiny SIM card in the correct orientation without dropping or damaging it. Plus, without a SIM slot and tray, iPhones have one less spot where water could get in and one less moving part that could break, and Apple doesn’t have to provide a SIM tool that you’ll likely lose (and replace with a paperclip).

Apple’s eSIM Transition

eSIM support is widespread among US carriers but less so internationally, which is why models of the iPhone 14 sold outside the US retain the SIM tray. The main place where lack of eSIM support is likely to be an issue—at least for the near future—is international travel. Historically, it was easy to purchase a pre-paid SIM card for a local carrier in the airport upon arriving, but that will no longer work for a US iPhone 14. The iPhone is sufficiently popular that international carriers are adding eSIM support, but it’s still possible to travel to a country where you can’t get local service with an iPhone 14 due to the lack of a SIM tray. Apple maintains a list of international carriers that support eSIM in various ways, including with pre-paid plans for travelers, and offers advice on how to use eSIM when traveling. (eSIM isn’t available at all in mainland China, but Apple’s list includes worldwide service providers that sell pre-paid data plans you can use when traveling in China and other countries without eSIM support.)

Apple has been moving toward eSIM for several years, starting with the iPhone XS, iPhone XS Max, and iPhone XR in 2018. Those iPhones—and every model up to the iPhone 14—had both a SIM tray and eSIM, which enabled the use of two separate cellular plans, each with its own phone number. With the iPhone 13, Apple enabled Dual SIM support with eSIM alone, and some carriers started giving customers the option to activate their primary service with eSIM, leaving the SIM tray or the second eSIM available for a second plan. Apple says you can store and switch among up to eight or more eSIMs, two of which can be active at any time, but it’s unclear how that works—an update to iOS might be necessary.

Cellular-capable iPads have had eSIM support since the seventh-generation iPad, fifth-generation iPad mini, third-generation iPad Air, first-generation 11-inch iPad Pro, and third-generation 12.9-inch iPad Pro.

How to Activate an eSIM

Precisely how you activate an account with eSIM varies by carrier and your situation, but Apple describes three basic options:

  • eSIM Carrier Activation: Some carriers can assign a new eSIM to your iPhone, making it easy to switch to a new iPhone or enable an eSIM-based plan after setup. eSIM Carrier Activation involves following a few simple onscreen instructions where you basically acknowledge that activation is happening. Make sure you can place a phone call afterward, and if you’re switching from a SIM card, remove it and restart your iPhone.
  • eSIM Quick Transfer: If you’re transferring a SIM or eSIM from an old iPhone to a new one and you have both at hand, you may be able to use eSIM Quick Transfer. It will provide instructions during setup, or you can initiate it after setup with Settings > Cellular > Add Cellular Plan and either selecting a plan from a list or tapping Transfer From Another Device. You can also convert a physical SIM to an eSIM on the same phone if your carrier supports eSIM Quick Transfer; check to see if Settings > Cellular has a Convert to eSIM option. If so, tap it and follow the instructions.
  • Scan a QR code or use a carrier app: Carriers that don’t support eSIM Carrier Activation or eSIM Quick Transfer initiate setup by providing either a QR code you can scan—during setup or afterward—or a custom app. Either way, follow the iPhone’s instructions to complete the setup.

Although we’ve become accustomed to swapping SIM cards in and out of our iPhones such that eSIM feels new and confusing, it should be a better overall solution that’s easier to set up, less error-prone, and more secure. There may be some short-term annoyance for US iPhone 14 owners who travel internationally, but we anticipate that will dissipate over time as international carriers start supporting eSIM.
