Replacement: None. We have unfortunately retired this product but you can always read about how we built it! This page is for reference only.

The infamous Portable Rotary Phone is an original rotary phone that has been modified to be a cellular phone. The Port-O-Rotary has a functional rotary dial, rings the original, loud metallic bells when a call is received, and even has a dial tone.

Phone comes fully assembled and tested. 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. The internal cellular module works within any country that has one of the 900MHz, 1800MHz, or 1900MHz cellular bands (90% of the world). The Port-O-Rotary is truly international with up to 15-digit dialing, auto-frequency selection, '+' characters, and PIN # entry for pre-paid cards.

Each Port-O-Rotary is an original rotary phone that has been specially modified. There may be small scratches and scraps on the exterior, also known as 'character'. The battery can run the phone for 4-5 days (yes days) and is charged by an external jack on the rear of the phone (charger included).
