Yes, the TSA absolutely allows cell phones in 2026, and they are considered a high-value necessity for modern air travel. You can carry your phone in your pocket, handbag, or carry-on luggage. During the high-fidelity security screening process, if you do not have TSA PreCheck, you are typically required to remove your phone from your pocket and place it in a bin or directly on the conveyor belt to pass through the X-ray machine. However, at many high-value airports equipped with the latest "High-Fidelity" CT scanners, you may be allowed to keep your phone inside your bag. It is a high-fidelity requirement that your phone be fully charged; security officers may occasionally ask you to power the device on to prove it is a functional electronic and not a high-value security threat. For 2026 travelers, your phone also serves as your high-fidelity digital ID and boarding pass, making it the most important high-value tool in your travel arsenal from the moment you enter the terminal.
