Very, for text. Paste a message, a menu, an address: a 4B multilingual model renders major languages in a second or two, no SIM card or wifi required. Download the model at home; abroad it costs nothing and works in the metro, the mountains, the plane.
Know the limits: photo-based translation needs a separate OCR step, voice needs a transcription app first, and low-resource languages get rough. For the big tourist and business languages, on-device quality is honestly sufficient.
