iPhone Camera’s Built-In Translations
If you won’t have service where you are going, it is best to have Google Translate already downloaded with your native language and target language. Make sure you download both of them before you are out of service!!
However, if you will have service at your destination, you don’t have to open a translation app to figure out what that sign means. Click the quick-open camera button on your iPhone (default on new phones is the bottom right side button). Then follow the directions below!
