Under Finnish law, a tie-in sale is defined as selling the equipment for a discounted price contingent on the consumer also acquiring a new service contract from the seller. Under the terms of a provisional exception, valid from 2006 until 2009, tie-in sales were permitted with 3G handsets, and 3G equipment which is purchased under such tie-in sales may be SIM-locked. The SIM lock must be removed free of charge at the conclusion of the tie-in contract, within a maximum duration of 2 years.

In the paper, the author stated that the average unlocking fee charged by Portuguese carriers is 90-100 euros.

Some companies also offer unlocking services that require sending the handset's IMEI number. Other companies sell unlocking hardware, including devices which fit between the SIM card and the phone to spoof the original network identifier during registration and devices to read and edit the handset's firmware. The pricing for unlocking a device will vary depending on the network it is locked to and the handset model itself, as each unlock code is unique to each individual handset.
