If there is a problem with unlocking, you need to:

If Samsung Galaxy S4 has a blockade for a subnetwork like Tesco or Virgin you need to use a SPCK (service provider) code.
It means that the Samsung Galaxy S4 can only receive signal from one network. If you insert a simcard from a different network, the device will ask for an unlock code, or will show the message that this simcard doesn't work.
Networks that can be unlocked include: AT&T USA, Orange, EE and many more.
