Choose the features you need
Translation apps can help read signs, menus and messages or support a short conversation. Papago is a translation app from Naver, a Korean search and online-services company. Google Translate, Apple Translate and supported Samsung Galaxy translation features offer other options.
There is no single app that is best for every sentence, device and situation. Check the supported languages and features on the current app or manufacturer's page, then try the tasks you expect to use.
Take a clear photograph for camera translation
Photograph the text straight on with good light and the whole sentence in view. Avoid glare, blur and cropping off the end of a line. A saved image can be easier to inspect than a moving camera view.
Check prices, dates, quantities and negative words carefully. A missed “not” or a misread digit can reverse the meaning. If the result is confusing, retake the photograph or ask someone to read the original.
Handwriting, calligraphy and stylised signs can be difficult. An app may produce a fluent-looking answer even when it has read the text incorrectly, so fluency is not proof of accuracy.
Test offline use before travelling
Download the required language packs where the app supports them. Then turn off Wi-Fi and mobile data and test text, camera and conversation modes separately. A working offline text feature does not establish that every other feature also works offline.
Google's camera-translation guide explains downloading languages for supported offline camera use. Apple's Translate settings guide explains downloaded languages and on-device settings. Availability depends on the device, software and language combination.
Keep important addresses and phrases saved in a form you can open without a connection.
Check phone-call and messaging features separately
A feature that translates spoken calls is different from one that translates written messages. Samsung's Live Translate guidance explains supported calling features and apps; check your exact phone and software.
KakaoTalk is a messaging app used widely in Korea. Do not assume that support for calls in a messaging app also means every written message will translate automatically.
Tell the other person if you are relying on translation and confirm important details in writing. For a conversation in person, speak in short sentences and allow time for each translation.
Get human help when an error would matter
For allergies, medication instructions, consent forms, payments or legal matters, do not rely only on an automatic translation. Ask the relevant professional to confirm understanding or arrange suitable interpretation.
1330 can help with tourism-related communication, while BBB Korea offers volunteer telephone interpretation. These services have their own limits; professional documents or specialist decisions may need a qualified interpreter or translator.
