Why venues choose phone tours
Visitors just call a number and start listening.
A no app audio guide removes the install step that can stop visitors before they ever hear the first stop. Instead of asking people to search an app store, create an account, or borrow hardware, you give them a number to call.

What it is
A call-to-listen tour for museums, attractions, and destinations.
A phone audio guide is a call-to-listen tour. Visitors dial a number you publish on signs, maps, tickets, or a QR code, then hear guide content for each stop. Phone tours need no app and no install, which makes them a simpler alternative to an audio guide app or a rented headset. For the broader category, read what an audio guide is.

How it works
Put the guide number wherever visitors need the story.
VoxiGuide structures the call flow around your stops, route, exhibits, or languages, then visitors call from their own phones when they are ready to listen.
Visitors call
They call from their own phone, choose the stop or route, and start listening.
Audio plays
A short sponsor message may play first, followed by your guide content.
They keep exploring
Visitors move through the venue and call again at the next stop or chapter.
Phone audio guide vs tour guide app
Remove the download step from the visitor journey.
A phone guide is not trying to win attention in an app store. It gives visitors a direct, familiar way to access the tour from the phone in their hand.
