Just to clear this up. If reported to Orange as lost/stolen the blacklisting is immediate, within 10 mins, for both the SIM & handset.
The blacklist data is shared with all UK networks...but this can take 3 months to be picked up.
The network that applied the blacklisting is the only one that can remove it.
But any network can blacklist a UK phone, no matter where it came from. As long as the IMEI is shown as being used with the account holders SIM it can be blocked if reported as lost/stolen. It cannot be blocked for non payment of a contract, if it's not the original handset or direct replacement. Or, if it does not show as being used with the account holders SIM.
Getting back to the thread.... The phone is working with an Orange SIM, so it is not blacklisted & won't be in the future as enough time has passed for the owner to report it.

if not press the green tab to tell me to f**Koff
