Phone unlock won't work

I followed this guide to unlock the phone

1. You need to launch the Service Mode on your phone; in order to do that tap "*#0011#" in the dialer of your handset. 2. The Service Mode will be displayed; now you need to tap on "menu" (left soft key) and from the dropdown menu select "back". 3. Press the Menu button once more and this time select "Key input". 4.. Tap on the pop-up box that will be displayed; then enter "1" and tap on "ok". 5. You now need to go back to the Service Mode menu; for that tap on "menu" and select "back". 6. From the Service Mode menu, this time select "[1] UMTS".

At stage 6.... there is no menu that says UMTS

It just simply takes me back to the original menu with stuff like "GSM900: Limited" etc

It takes me back to the very first menu after I dialled "*#0011#"

So.... what do I do...??

The reason I'm trying to unlock the phone is that it said, "Network not registered".... It won't let me connect to an EE network at all... so I thought maybe the solution is to unlock the phone.

Thanks
