What it does
Test calls check whether they reach real smartphones and whether Caller ID displays correctly.
Why it matters
The checks show call-delivery and routing issues across carriers, networks and locations.
Requirements
The task needs an eligible smartphone with an active SIM that can receive calls. Wi-Fi alone is not enough.
- Opt in
- Report the exact Caller ID within the reporting window
- You do not need to answer the call
- No minimum attestation
What affects incentives
Availability depends on location, carrier and demand. Eligibility is subject to current requirements and validation. Incentives vary and are not guaranteed.
Participation requires an eligible device, license, available task, and verified activity. Task availability, eligibility, requirements, validation, timing, and rewards vary and are not guaranteed.
Rules
Report what is displayed; do not guess or alter it.
