TV
Yes, you can change language settings on most Freeview TVs and boxes, although not the language that programmes are broadcast in.
How to do this will depend on your device. For the most up-to-date information, we recommend you check your user manual (if you can't find it you may be able to find it on the manufacturer's website) or get in touch with the manufacturer directly.
APP
At the moment there are no plans to provide the Freeview mobile app in other languages. We'll let you know if this changes, though.
