Barcelona is not a dangerous city. But there are pickpockets. For this reason, here are some safety tips to make your life in Barcelona easier:

• If you are a victim of a crime, ask for help from a police officer or call 112, the number that works for emergency services; includes ambulances and fire brigades. It's free, works 24 hours a day, 7 days a week, and you can even call from a cell phone even if you don't have coverage from your provider (through another company). Operators can help you in 50 languages. There is also "my 112", a very useful and free mobile application that you can download; if you access the service, your phone will use geolocation to identify where you are.
• Be aware of your belongings when using public transportation, especially with your mobile and money.
• In crowded places, fasten your bag or camera to the front of your body instead of your back. Use a secure locking system such as a zipper or padlock, and always make sure it is securely fastened.
• On the beach, if you are alone and want to go to the water, it is better to leave your valuables at home.
• Avoid showing money or your mobile phone in public places. Don't carry large amounts of money. In bars or restaurants, ask for prices first and avoid surprises when paying.
• You may come across people who try to distract you with various excuses; saying you have stains on your clothes, selling roses, asking for help with a map ... Do your best to avoid them, as they could be pickpockets.
