Global cellular smartwatch shipment growth accelerated to +15% YoY in the first quarter of 2023, despite a total smartwatch market decline, as cellular penetration rose due to the Apple Watch Ultra and Google Pixel Watch. Albeit from a low base, cellular smartwatches are outperforming the overall smartwatch market as cellular penetration among smartwatches continues rising slowly but steadily. Apple and Samsung are leading the way across developed markets and Apple's addition of the Ultra (their first smartwatch coming standard with LTE - no Wi-Fi only variant) has driven up cellular penetration in recent quarters. Major carriers, like Vodafone and Verizon, are starting to push hard on this segment. Our report tracks global cellular smartwatch shipments and marketshare by leading hardware vendors by quarter.
