This rotary phone is a vintage item produced in the 1980s in Hungary. We have saved and upcycled some of these phones for you. Rotario works with all mobile phones that has Bluetooth® onboard. Rotario has the original rotary dial, ringtone and dial tone. You just have to pair your mobile with Rotario and use it as any other external handsfree device. Manage all your calls just like in the old days and adjust the ringer volume with the integrated knob. Your phone will arrive of course fully assembled and tested...and there is even a battery inside so you can use it wireless if you need to go.
