Most hotels have safes so that travelers can store important belongings while the room is being cleaned or they’re out on the town. Before you go out, place your passport, house keys, excess cash, and expensive jewelry in the safe and lock it. If you are pickpocketed, you’ll only lose some of your money and belongings. Always leave some extra cash in your hotel safe. In the event that you are pickpocketed, you’ll still be able to get a ride and feed yourself before you can rectify the situation. Keep your phone in an interior pocket that isn’t easily accessible to pickpockets. Try your best to avoid pulling it out frequently, especially when you’re focused on finding directions. If you do have to take your phone out, hold it firmly with both hands and don’t stare at it for more than 5-10 seconds at a time.  When you take your phone out to take photos, always put it back in your pocket when you’re done. Turn down offers from strangers to take your photo with your phone. Print the maps that you need at the hotel to avoid needing to use your phone to figure out where you are. Even if you don’t want to use it, it’s still a good idea to keep your phone on you. You never know when you’re going to need to make an emergency call. If you wear jewelry, tuck your necklaces into your shirt so that they can’t be ripped off of your neck. Don’t bring your watch with you if it’s worth more than a few dollars. Avoid bringing jewelry with a lot of gemstones on them, regardless of whether they’re real or not.  Unless they’re incredibly loose, your rings are probably fine. They’re pretty hard to lift without you noticing. Be wary of wearing rings with gemstones in them, though. If you’re wearing a lot of jewels, pickpockets are more likely to assume that you’re carrying a lot of cash. If you can, don’t bring any jewelry on your trip. Unless you’re going out to a fancy dinner or show, there’s no need to bring it along.
