If I were travelling to Costa Rica, I would leave my phone at home along with most other valuables. US Government has posted this warning. "Thieves often work in small groups. The most prevalent scam involves the surreptitious puncturing of tires of rental cars, often near restaurants, tourist attractions, airports, or close to the car rental agencies themselves. When the travelers pull over, "good Samaritans" quickly appear to help change the tire - and just as quickly remove valuables from the car, sometimes brandishing weapons. Drivers with flat tires are advised to drive, if at all possible, to the nearest service station or other public area and change the tire themselves, watching valuables at all times. Another common scam involves one person dropping change in a crowded area, such as on a bus. When the victim tries to assist, a wallet or other item is taken."
