Phase119 · Used Smartphone Purchase Flow Integration
One used-smartphone purchase journey from exact model to final safety result
Model compatibility alone is not enough, and neither is cosmetic condition. This flow connects SolQvia’s existing checks in the order: model → lifecycle → repair → individual device → final result.
How the used-smartphone purchase flow works
A used phone should not be judged by price or product popularity alone. SolQvia separates the decision into exact-model and network fit, OS/security lifecycle, repair and battery-service routes, and the condition of the actual device being purchased. The final purchase-safety diagnosis comes only after those layers are checked.
The early steps describe model-level conditions; the later step describes the individual unit. A compatible model can still be a poor purchase if ownership protection remains active, network restriction fails, critical hardware is defective or serious liquid damage is present. Missing evidence is kept as a verification requirement rather than automatically being labeled safe or unsafe.
Purpose of this page
This is a navigation layer that keeps the checks in a consistent order. SolQvia does not store IMEI or other device identifiers; where a carrier lookup is required, the official carrier tool is used and only the result is carried into the decision.
How to use this flow
- Choose the exact model/variant and original carrier where possible.
- Use Phase116 for SIM/eSIM, FeliCa and network-fit gaps.
- Use Phase117 for OS/security lifecycle and Phase118 for repair/battery-service routing.
- Once you have an actual listing/device, use Phase115 for network restriction, ownership lock, battery, warranty and the final result.
Do not enter IMEI, EID, ICCID, phone numbers or account data. Check network restriction on the carrier’s official site and enter only the result in Phase115.
Comparison comes after the final diagnosis
Phase119 does not link directly to seller/price comparison. Luqevora comparison is shown only after Phase115 returns candidate or conditional.
