The cost of a bad buy
Trade-in margin dies in predictable ways:
- Function fails you didn’t catch — dead mic, cracked rear camera that still “looks fine,” flaky sensors
- Locks and accounts — iCloud/FMiP/MDM and similar signals when available at intake
- Blacklist / carrier-lock risk — paying out before you know the device’s status
- Inconsistent grading — Grade B on Monday isn’t Grade B on Saturday if every tech grades from memory
Larger buyback platforms exist for high-volume programs. Many shops need something simpler: fast, consistent diagnostics, clear reports, and a price that makes sense before the next payout window.
Workflow: station → grade → document → optional secured data erasure
-
Agent / station — Bring the device to the Check Up agent/station workflow
-
Instant Diagnostics — Internal + interactive diagnostics for iOS and Android
-
Mobile App Diagnostics — Display, cameras, audio, sensors, controls, connectivity
-
Device info / locks when available — Specs, SIM, battery, lock-related status (iCloud/FMiP/MDM and similar); service history available so you know what’s been replaced (iOS)
-
IMEI blacklist & carrier lock (Premium) — 55 blacklist/mo; carrier lock check included to sample (add-on packs if you need more)
-
Grade — Apply grading profiles so payout language stays consistent
-
PDF reports & labels — Hand the next person a record, not a verbal “looked OK”
-
Optional secured data erasure — for a clean handoff when the device leaves the bench
Device history stays in your workspace (1 month Free · 6 months Premium).
Blacklist & carrier lock on Premium
A carrier (or network/SIM) lock check shows whether a device is locked to a carrier or unlocked. If it’s locked, shops need to know which carrier, whether that carrier fits the buyer (you don’t want to be stuck with a phone locked to a carrier that doesn’t matter to the customer), how lock status changes device pricing, and whether there are financial obligations on the device — separate from IMEI blacklist status.
Free is for proving diagnostics.
Premium adds:
- 55 IMEI blacklist checks per month
- Carrier lock check included to sample (add-on packs if you need more)
Use Free while you validate Instant Diagnostics and Mobile App Diagnostics on trade-in intake. Upgrade when buying devices is part of the job and you need risk checks before cash out.
Start Free for diagnostics — upgrade when you’re buying.
Deep dive: IMEI blacklist check for business · Carrier lock vs blacklist
Built for trade-in & buyback desks
Check Up is for:
- Trade-in / buyback shops that need functional testing before payout
- Shops that buy used phones and want grading + PDF documentation
- Repair shops that also run a trade-in counter and need one diagnostics station
Check Up is diagnostics-first — not a full buyback POS or inventory commerce suite. If you need station diagnostics, grading, reports, and clear Free → Premium pricing, you’re in the right place.
Pricing — Free vs Premium
Free — $0 / €0 / £0
- 5 device checks / mo · Multiple stations (workspace-wide limits) · 1 month history
Premium — US $25 / EU €21.90 / UK £19.90
- 250 device checks / mo
- 55 IMEI blacklist · Carrier lock check included to sample (add-on packs if you need more)
- Multiple stations (workspace-wide limits) · 6 months history · users & roles
Upgrade when: you’re out of checks, trade-in volume needs blacklist/locks, you need separate logins/permissions (users & roles), or longer history.
Grading + reports that survive a dispute
Payout arguments often start with “you said it was fine.” Trade-in desks that export PDF reports and labels and apply grading profiles have a record: what failed on Mobile App Diagnostics, what device info showed, what grade was assigned, and — on Premium — whether blacklist or carrier lock was checked within plan limits.
Build the habit:
- Same Instant Diagnostics path every unit
- Same Mobile App categories every unit
- Grade from a written profile, not from shift mood
- Label the bag/bin so the next person doesn’t re-guess
For the full grading framework, see How to grade a used phone for trade-in. For station cabling and flow, see USB agent diagnostics station setup.
Free → Premium for buy desks
Start Free when you need to prove diagnostics this week without a purchase order. Upgrade to Premium when:
- You’re buying enough phones that 5 checks/mo isn’t enough
- You need IMEI blacklist (55) or a carrier lock sample before payout
- You need separate logins and permissions → Premium users & roles (Free already supports multiple stations; limits are workspace-wide)
- You want 6 months history

Questions, answered
Frequently asked questions
How does Check Up reduce trade-in payout risk?
By running Instant Diagnostics and Mobile App Diagnostics before you pay out, documenting grades with PDF reports/labels, and — on Premium — running IMEI blacklist and carrier-lock checks within plan limits.
What’s included on Free for trade-in desks?
Free includes 5 device checks/mo, multiple stations (workspace-wide limits), and 1 month history for diagnostics, grading, and reports. Blacklist (55/mo) and a carrier lock sample are on Premium (add-on packs if you need more).
What kind of wipe does Check Up support?
Secured data erasure for a clean handoff — when the device leaves the bench and your process requires a clean handoff.
How does Check Up compare to larger buyback platforms?
Larger suites often bundle commerce, inventory, and enterprise workflows. Check Up leads on diagnostics-first freemium clarity and published Premium pricing for repair & trade-in shops. See also Check Up vs NSYS.
Can I grade trade-in phones consistently?
Yes — use grading profiles so each grade means the same thing across shifts, then export PDF reports and labels, device history reports.
Is Check Up a full buyback POS?
No. Diagnostics-first — not a full POS.
