UCaaS Mobility’s Best-Kept Secret is in the SIM
Most UCaaS mobile apps are good enough for a home office or hotel room. They are not good enough for employees who spend their days in the field — and most of those employees know it, which is why they bypass the app entirely and use their personal phone. The enterprise loses call logging, compliance visibility, AI context, and corporate caller identity on every one of those calls. SIM-based UCaaS mobility solves this by moving enterprise phone numbers directly onto the device’s native SIM, eliminating app friction without sacrificing platform control. In this independent analysis from Light Reading, industry analyst Dave Michels of TalkingPointz examines real-world deployments across Microsoft, Cisco, and Crexendo — including how one NetSapiens partner reversed a multi-year decline in UCaaS adoption by extending SIM-based calling to every field technician they serve.
