Check how many devices are in an area over a time period. You can filter by roaming status and device type.
Specify a circular area and time period to get a response with the number of devices in the area.
Count only roaming devices to estimate the number of foreign visitors.
Count only IoT devices, such as sensors and shared bikes.
FilterFilter by roaming status and device type, separately or together.
Privacy thresholdIf there are too few people, no count is returned to protect individual privacy.
Region Device Count: How it works
- Set areaThe service provider sends a circular or polygon area and the start and end times.
- Set filtersYou can count only roaming devices or devices of a specific type.
- Count responseThe operator responds with the device count and area support status.

Region Device Count: GSMA use cases
QoD for PoS transactions at events
Problem to solvePoint-of-sale transactions at events need stable, fast connections.
Region Device Count's roleTracks crowds in each area to focus network improvements where needed.
