Editing SIM lock (section)

=== Portugal ===
A 2006 study sponsored by the [[Portugal]] regulator, [[Autoridade Nacional de Comunicações|ANACOM]], on handset subsidies and SIM locking concluded that there are no special regulatory concerns on offering subsidized SIM-locked equipment in exchange for signing a contract tying a customer to a particular  network.  Network providers are allowed to apply SIM locks as they see fit, and they may voluntarily remove them if they choose to do so.  In the paper, the author stated that the average unlocking fee charged by Portuguese carriers is 90-100 euros.<ref>{{cite web|url=http://www.anacom.pt/streaming/est22112006.pdf?categoryId=218502&contentId=424227&field=ATTACHED_FILE|title=Handset Subsidies – an Empirical Investigation|website=anacom.pt|access-date=22 March 2018}}</ref>
A recently approved law<ref>{{cite web|url=http://www.anacom.pt/render.jsp?categoryId=337488 |title=ANACOM - Desbloqueamento de telemóveis - novas regras |publisher=Anacom.pt |date=2010-07-13 |access-date=2013-06-21}}</ref> requires network operators to unlock a device free of charge if the respective contract has already expired (But they refuse to do so charging at least 10 euros). It also establishes limits to the fees that operators may charge to unlock a device while it is still under contract.
