Mobile & IoT, delivered as one portfolio.
Dollu's mobility portfolio brings our carrier relationships to bear on the mobile side of the network: multi-IMSI SIMs and eSIM profiles that roam onto 600+ networks, a connectivity-management platform for fleets of devices, and wholesale roaming and signalling services for operators and MVNOs.
For enterprises deploying trackers, meters, payment terminals, vehicles or industrial sensors, we deliver a single SIM SKU, a single portal and predictable global pricing. For operators, we deliver roaming steering, testing, clearing and SS7/Diameter signalling with security built in.
