Nokia 3110c shows phone restricted undo - Nokia 3110 Cellular Phone

SOURCE: RESTRICTION CODES

Special Code/Service Provider Lock Code:
This code is required to allow a phone locked to a particular network's SIM cards to be used with a SIM card from another network. Orange and T-mobile lock handsets in this way, though O2 and Vodafone are beginning to lock PAYG and WAP handsets. The unlock code varies from individual handset to handset.
Blacklisting:
This is not a security code, but it works like one! To help combat mobile phone thefts, the networks share a database of the IMEI (International Mobile Equipment Identity) of mobile phones that have been reported stolen. Once a phone is on this list, it will not be allowed to use any of the networks.
This can be a risk if you buy a second-hand phone, because if it has been stolen, or if an unscrupulous seller makes an insurance claim after selling, the phone you bought in good faith may be permanently disabled.
Be very careful to check the source of a second-hand phone!
