When it comes to staying connected while travelling, airports often provide a range of options for phone service. While airport Wi-Fi is typically available, it may not always be reliable for making calls, especially over VoIP services. However, travellers can usually rely on mobile phone networks, ensuring their roaming option is active. Payphones are also available at most airports, although they may be inconvenient and expensive to use. In case of emergencies, airport information desks may allow travellers to use their phones.

What You'll Learn

Phone searches by TSA and CBP
While the Transportation Security Administration (TSA) does not conduct phone searches, the U.S. Customs and Border Protection (CBP) has the authority to inspect electronic devices, including phones, when entering the country. These searches are conducted at ports of entry, and CBP officers can search a traveller's phone, computer, or other electronic devices during the inspection process. It is important to note that these searches are relatively rare, with less than 0.01% of arriving international travellers encountering them in Fiscal Year 2024.
CBP can search electronic devices without a warrant, and this includes accessing texts, photos, browsing history, social media, and financial information. While U.S. citizens cannot be denied entry for refusing to unlock their devices, their devices may be confiscated. For green card holders, device confiscation and potential immigration consequences may occur, while visa holders may face visa revocation and denial of entry.
To minimise the risk of sensitive information being accessed, travellers are advised to be mindful of their social media activity and consider deleting posts or messages that could be misinterpreted or seen as critical of the U.S. administration. Additionally, travellers can store their information on the cloud instead of their physical devices, ensuring that no data is stored locally that they would not be comfortable showing to a government official.
If travellers believe their rights have been violated during the screening process, they can file a complaint with the TSA. It is important for travellers to know their rights regarding phone and electronic device searches, as legal requirements and regulations can change.

Phone confiscation
While the Transportation Security Administration (TSA) does not conduct phone searches, the U.S. Customs and Border Protection (CBP) has the authority to inspect electronic devices, but only when travellers are entering the country, not departing. CBP can search electronic devices without a warrant, including texts, photos, browsing history, social media, and financial information. However, they cannot deny entry to US citizens who refuse to unlock their devices, but they may confiscate the devices temporarily.
For non-US citizens, the consequences of refusing to unlock electronic devices for inspection by CBP vary based on immigration status. Green card holders may face device confiscation and potential immigration consequences, while visa holders may be denied entry and have their visas revoked. Only US citizens have the right to legal representation at border inspections.
TSA agents primarily focus on physical threats to ensure nothing dangerous gets on a plane, so they usually have no need to inspect phones. However, if there is a reason to suspect that a device could be potentially dangerous, they may ask travellers to power on the device and open some apps to demonstrate that it is fully operational and untampered with.
To prevent potential issues and delays, travellers can take precautions such as leaving electronic information off their devices and using cloud storage to access it after their trip. Additionally, travellers should be aware of other items that may be confiscated by airport security, such as portable chargers, cell phone batteries, laptop batteries, external batteries, and power banks that are packed in checked luggage. These items are classified as "carry-on only" due to strict safety requirements.

Phone charging
While it is possible to charge your phone at the airport, it's important to be aware of the potential risks involved. Public USB charging stations, which are commonly found in airports, have been flagged by the FBI as a potential vector for "juice jacking". This is when cybercriminals use modified USB sockets to install malware and monitoring software onto your device. In other words, charging your phone at the airport could potentially lead to the theft of your personal and private information.
However, there are ways to keep your data secure while charging your phone at the airport. Firstly, carry your own charger and USB cord, and use a power outlet instead of a USB charging station. If you must use a USB charging station, consider purchasing a portable charger or power bank, and always use a USB data blocker or a power-only USB cable to prevent data transfer between your device and the charging station. Additionally, locking your phone will shut off data transfer over the USB port, making attacks impossible. Keeping your device and its apps up to date can also provide further protection.
It's also important to be cautious when using airport Wi-Fi, as public Wi-Fi networks can also be used to conduct data theft. Consider purchasing a VPN (virtual private network) to protect your data when using public Wi-Fi. Finally, always keep an eye on your devices in crowded places like airports to prevent physical theft, which can also lead to significant data breaches.

Phone safety threats
While the Transportation Security Administration (TSA) does not conduct searches of electronic devices, they may request that you turn on your device to prove that it is a working device and that its batteries are not hidden explosives. This is a response to an al-Qaida bomb threat. If the internals of your device look suspicious when it goes through the baggage scanner, TSA agents may inspect it to ensure that it is untampered with. They may ask you to power on your device and open a few apps to show that it is fully operational. However, they would need a warrant to do so.
When travelling internationally, the U.S. Customs and Border Protection (CBP) has broader authority and can search the contents of your phone without a warrant, regardless of your citizenship status. They can confiscate your device, download data from it, and save it to their databases. However, they cannot deny you entry into the country if you are a U.S. citizen, but they can do so if you are a visa holder.
To ensure safety, it is recommended that you keep your electronic devices charged when passing through airport security. You may also be required to undergo a pat-down procedure to determine whether prohibited items or other threats are concealed on your person. These procedures are conducted by an officer of the same sex, who will explain the process to you.

Privacy rights
U.S. Customs and Border Protection (CBP) officers have the authority to search electronic devices, including phones, laptops, and other devices, when entering the country. This power is not limited to airports but extends to any border crossing. CBP officers can request that travellers hand over their devices for inspection, and while travellers have the right to refuse, doing so may escalate the situation and result in the confiscation of their devices.
It is important to note that the Transportation Security Administration (TSA) does not have the authority to inspect electronic devices and should not request access to them during security checks. However, TSA officers can search your bags and conduct further searches if necessary. They may also ask you to power on your electronic devices and open certain apps to demonstrate that they are fully operational, but they should not be accessing your personal information or content.
To protect your privacy, travellers can take steps such as encrypting their data before travelling, using strong passwords, and conducting a personal risk assessment to determine the sensitivity of the data on their devices. Additionally, if you believe your rights have been violated, you can file a complaint through the CBP's website or seek information from organisations like the Electronic Frontier Foundation and the American Civil Liberties Union.
Travellers should also be aware that their rights and the potential ramifications of non-compliance may depend on their immigration status and travel history. Constitutional protections are generally weaker at U.S. borders, and CBP officers have broad authority to search electronic devices without a warrant. As legal requirements and regulations can change, it is essential to stay updated on your rights regarding electronic device searches when travelling.
