How many IoT devices exist in the world in 2026?
Short answer
By 2026 there are approximately 20-22 billion active IoT connections worldwide, per Ericsson Mobility Report and IoT Analytics estimates. Around 4.5 billion are cellular (SIM/eSIM); the rest are non-cellular LPWA, Wi-Fi, and Bluetooth. The projection for 2030 sits at 30-40 billion.
By connectivity type
Short-range (Wi-Fi, BLE) still leads in unit count: home and wearables. Cellular IoT grew from 2 billion in 2020 to ~4.5 billion in 2026, driven by NB-IoT and LTE-M. LoRaWAN and Sigfox combined are around 500 million.
By region and sector
China has the largest absolute volume (metering, surveillance). Europe leads in industrial density (4.0) and connected vehicles (eCall). Spain ranks in the top five EU countries for NB-IoT adoption per operator reports.
What it means for your project
There is scale: components, operators, and platforms have mature offerings. But also heterogeneity: there is no 'one IoT solution' — design for your specific case.

Frequently asked questions
Are these numbers reliable?+
They are estimates — nobody has a precise global census. Ericsson, IoT Analytics, GSMA, and Berg Insight provide comparable ranges and are used as industry reference.
Which sector grows fastest?+
Connected automotive (eCall, telematics), smart metering, and logistics. In all three, cellular SIM is the dominant connectivity.
How many new cellular IoT SIMs activate per year?+
In 2026, around 500-700 million new cellular IoT connections yearly. Over 70% are NB-IoT or LTE-M.
