To ensure you don't lose your phone on a rollercoaster, the "gold standard" is to use zippered or button-down pockets. Standard open pockets are notorious for letting phones "slide out" during inversions or high-G maneuvers, where the phone's weight can overcome the friction of the fabric. If your clothing doesn't have secure pockets, a "Fanny Pack" or a "Running Belt" (like a FlipBelt) is the most effective and park-approved way to keep your device snug against your body. For "high-thrill" rides like VelociCoaster or Iron Gwazi, park regulations often mandate that all loose items—including phones—must be placed in the complimentary lockers at the attraction's entrance; trying to sneak a phone on board can lead to you being removed from the park. If you absolutely must have your phone for a "POV" video (on rides where it is legally permitted), use a heavy-duty wrist lanyard or a dedicated "action camera" mount. However, in 2026, most major theme parks have a "Zero Tolerance" policy for handheld phones on rides, so the best way to not "lose" your phone is to follow the rules and keep it securely locked away while you enjoy the thrill.
