The carrier will also have the physical check IMEI number to know if the device is locked, unlocked or in contract.

Carrier lock merely limits the phone to certain mobile networks, whereas iCloud (Apple) or Google FRP lock is aimed at restricting the user's access to the phone itself. Phones carrying a "clean" IMEI don't always mean they're unlocked; the carrier restrictions may still apply, even when they haven't been blacklisted.

Wrong IMEI number

Slow or outdated data

Occasionally, carrier databases will not get updated immediately, which in turn may result in outdated or delayed information. Recent events, such as unlocking or carrier switching, will most likely not be reflected instantly in the report.

Unknown results

Sometimes the result of a check might be "unknown" or partially filled. This case is often observed when dealing with brand-new gadgets or carriers that are not completely supported by all IMEI tools, and it does not necessarily mean that there is a problem with the phone.

Different results in different regions
