Check Up pairs station diagnostics with Premium IMEI blacklist (55/mo) and a carrier lock sample so shops can try the check on real buys — so buyback and repair shops can control payout risk inside the same workflow. Carrier lock lookups are expensive; volume beyond the sample is available as an add-on when you need more.

Why consumer IMEI sites fail shops
A random “check this IMEI” page might answer one question once. Shops need more:
- A workflow — connect the device, run diagnostics, then risk-check before cash out
- A device record — PDF reports, labels, and history your team can reopen
- Team logins — Premium users & roles when you need separate logins and permissions (Free already supports multiple stations; limits are workspace-wide)
- Plan clarity — known monthly limits, not surprise per-lookup fees buried in fine print
Check Up is built for repair shops and trade-in / buyback shops: diagnostics-first, with blacklist and carrier-lock on Premium within published plan limits.
Check Up flow: diagnostics + blacklist on Premium

Carrier lock vs blacklist
Blacklist and carrier/SIM lock are different risks. Blacklist often maps to blocked / stolen-device databases. 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. For a shop-friendly explanation, see our guide: Carrier lock vs blacklist. Premium includes blacklist plus a carrier lock sample (add-ons for more carrier lock volume).

Pairing blacklist with diagnostics (why shops upgrade)
An IMEI hit alone doesn’t tell you if the mic works. A clean blacklist result doesn’t tell you if the rear camera focuses. Trade-in / buyback shops that protect payout margin run both: functional diagnostics first (or in the same station visit), then blacklist and carrier lock on Premium before cash leaves the till.
Typical upgrade path:
-
Week 1 — Start Free, run Instant Diagnostics + Mobile App Diagnostics on five real buys or intakes
-
When Free’s five checks aren’t enough — or when you’re about to pay out on a high-value unit — move to Premium for 250 checks, 55 blacklist, and a carrier lock sample (add-ons for more volume)
-
Add users & roles when you need separate logins and permissions for buyers/QC (Free already supports multiple stations; limits are workspace-wide)
-
Keep 6 months of device history reports so disputes aren’t “he said / she said”
Regional Premium pricing stays published: US $25 · EU €21.90 · UK £19.90 — plan the month’s blacklist budget against the 55-check cap rather than guessing per-lookup fees.

Frequently asked questions
Where is IMEI blacklist available?
On Premium — 55 IMEI blacklist/mo, plus a carrier lock sample (add-on packs if you need more), plus 250 device checks. Free includes Instant Diagnostics, Mobile App Diagnostics, grading, PDF reports/labels, and device history reports (5 checks/mo · Multiple stations (workspace-wide limits) · 1 month history).
What is a carrier lock check?
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. Premium includes a carrier lock check so you can try it on real devices. Need higher volume? Add-on packs are available — these checks are costly, so we don't bury unlimited lookups in the base plan.
How much is Premium for business IMEI checks?
Premium is US $25, EU €21.90, or UK £19.90 per month, including 55 IMEI blacklist checks and a carrier lock sample, plus 250 device checks, roles, and 6 months history.
Who is this for?
Repair shops and trade-in / buyback shops that need business-ready IMEI blacklist checking paired with functional diagnostics — not a consumer one-off lookup.
Can I start Free and add blacklist later?
Yes. Start Free for diagnostics; upgrade to Premium when buying devices requires blacklist and carrier-lock risk control.
Is Check Up a full buyback POS?
No. It is diagnostics-first, not a full POS.
