Comparison basis: Public information and prior research as of April 23, 2026 JST. Final decisions should still be made against a live trial, certificate samples, and your actual throughput pattern.
| Axis | MASAMUNE fit | When Phonecheck-style selection may fit better |
|---|---|---|
| Primary workflow | Domestic resale, red-ROM avoidance, and proof output in one operator path | You want inspection-first workflows with less emphasis on traceable evidence |
| IMEI handling | Placed inside the same path as erase and decision-making | IMEI is handled elsewhere or is not part of the critical path |
| Evidence | PDF certificate, QR, and cloud log explanation stay connected | Inspection details matter more than evidence continuity |
| Pricing entry | Zero upfront cost and easy PoC entry | You are already aligned to a different contract structure |
When MASAMUNE fits best
Teams that want IMEI handling, activation-lock checks, and certificate flow in one operational route.
What to align before comparing
Monthly volume, inspection scope, certificate expectations, and whether domestic IMEI handling is in scope.
Where the real advantage appears
The difference often shows up in reduced handoff mistakes between IMEI judgment and evidence generation.
We can compare under matched assumptions.
Tell us your monthly volume, IMEI need, and evidence requirement, and we will frame the comparison correctly.
