Samsung Galaxy S4 Unlock

Hi,
I have a Samsung Galaxy S4 Att with Android 5.0.1. I requested unlock code from att and the code they gave me is not working.
Can some one help me with unlocking the device.
Thanks,
Sravan.
I haven't seen anything about unlocking an S4 running 5.0.1, but you can flash the phone back to nb1 base and unlock it. Then when you flash back to 5.0.1 the unlock should stick. See this thread on unlocking, for instance. See this or this for flashing back to 5.0.1.
Disclaimer: I do not own an S4 so can not test this.
You may be able to find more information in the forum here if you search.
First of all I can't believe AT&T actually gave you an unlock code that's amazing the best bet to sim unlock your phone is to downgrade your modem then use region lock away then upgrade your modem again then boomshockalocka you will have a sim unlocked device

Does anybody know how to unlock Samsung Galaxy S4 uk model ?

I'm new to this website
A little searching will do you. We have an entire thread on unlocking these phones in the general forum. However, if your S4 is a black edition (I9506) or value edition S4 (I9515) you'll have to pay for an unlock code. This is because unlocking requires installing the correct modem, and those devices never had the correct modem available for them.
