iPhone 18 Duo Availability and Price in Kenya

The Apple iPhone 18 Duo was announced at Apple’s September 2026 event alongside the iPhone 18 Pro and iPhone 18 Pro Max — introducing the “Duo” naming to replace the “Plus” line with a new dual-identity: a larger 6.9-inch display in a slim, ultra-light design powered by the A19 chip with the full Apple Intelligence feature set. The iPhone 18 Duo price in Kenya is available at Simu Store Kenya, where it can be ordered in Sky Blue, Starlight, Midnight, Pink, and Turquoise colour options in 128GB, 256GB, and 512GB configurations.
