All GSMA-related statuses at a glance

In a wholesale lookup report, each IMEI returns one of a handful of statuses. The first column is the label you will see; the second column is what it actually means; the third column is what to do as a wholesale buyer.

Does Clean mean the phone is safe to buy?

It is the minimum baseline, not full proof. Clean only refers to the GSMA blacklist. A Clean phone can still be carrier-locked, iCloud-locked, MDM-enrolled, or under a financing balance. Always run the next-step checks before paying.

Can a blacklisted phone be cleared?

Sometimes, if the original report was filed in error and the original reporter cooperates. Insurance-paid blacklists are usually permanent because the insurer effectively owns the device. Unauthorised IMEI removal via reflashing is illegal in most jurisdictions and is the standard marker of grey-market refurb fraud.

Is GSMA status the same as iCloud Activation Lock?

No. GSMA blacklist and Apple iCloud Activation Lock are separate systems. A phone can be Clean on GSMA but still locked to a previous Apple ID. Always run an Apple GSX or paid iCloud-lock check on iPhones alongside the GSMA blacklist check.
