Nokia Codes for the Classic Business Series (6xxx Series) remote unlock codes:
Below you will find the Nokia Classic Business Series (6xxx Series) mobile phones for which unlox.co.uk can currently provide an unlocking service using remote Nokia unlock codes.
Most mobile phones have a 'Network Restriction' which prevents the use of any alternative network Sim card. You will normally see the message "SIM Card Not Accepted", "Enter restriction code" or "Sim Card Rejected". In order to enable the use of an alternative network Sim card, the network restriction has to be removed. This can be achieved with 'Unlocking Codes' which is the safest, quickest and least expensive method available!
