The PRP v1.1 Retro Rotary Mobile Phone. Insert SIM card, pop it in your pocket (!) and bingo, you’ve got the coolest, most awesome mobile phone on the planet. Sit at a table in your local cafe and be the envy of your fellow diners – if they believe you. Even when it rings with an incoming call. Still, what a gas. Tri-band, 4/5 days standby per charge, custom built with 2 weeks delivery. The only slight problem is…ahem…$499.00.
All you have to do is open the phone, insert your SIM card, and turn the unit on! The unit will utilize your phone number and account minutes. Phone dials out like normal through the rotary. Incoming calls ring the original, loud, gong style metal bells. Please note: As with all cellular phones, there is no dial tone. While we thoroughly enjoying taking the Port-O-Rotary out on the town, please realize the sound quality will not be as good as your pocket phone. This phone is for entertainment purposes only!
Or you can go here, and learn how to build one yourself. I am currently converting an old wall mount rotary into a center console mount car phone for my s-10 blazer.
