hello i bought my z3 with ee . now want to unlock it to use different network but when i typed unlock code says unsuccesfull also had mail from ee which says

If the code is not accepted, on the call screen type in *#*#7378423#*#*

This should bring up a menu.

Tap on service info
Tap on SIM lock

If the number next to “Network” is zero, you would need to visit sony. but i couldn't find any answer. hoper someone knows how deal with it thank you.

How many times did you enter the incorrect code?
If more than 5 it is most likely hard locked to ee and would need some serious work to unlock it.
What does it say in the SIM lock menu?
Post a screenshot if you can

Hi @bullet1917, welcome to the forum!

As @Viridis wrote if you could provide us with information regarding how many attempts you have left it would be really helpful.

Start the phone without a SIM-card and open up the phone application, type in *#*#7378423#*#* > tap service info > tap SIM lock. Which number is displayed next to "Network"?

If it says 0 here I'm afraid you have used up all your attempts to unlock the SIM network and the phone has to be sent in to a authorized service centre. I will not be able to assist you with getting the phone sent in but your Local support can assist you with this!

Let me know if anything is unclear!

I'm sorry I forgot to mention what @Viridis is asking.

Is there an "X" in the checkbox next to "Network" in the service menu? Below you will find a screenshot of this menu.

If there is an "X" in this checkbox and you see "0" after "Network" the phone is locked to a specific operator and you have no attempts left to unlock it.

To get new attempts the phone will have to be sent to a authorized service centre. Your Local support can assist you with getting the device sent in.

Let me know if there is anything else I can assist you with.

Hi, what if my phone shows network subset unlimited? Will I be able to unlock it?
And also the problem is the part where you're suppose to enter the unlock code, it doesn't show up. Where do I put the code? I tried inserting the new sim but when I restart the phone nothing happens it just goes right to the launcher and shows PERSO LOCKED.

Btw, my phone is Sony Xperia Z3 401SO from Softbank

Please reply. Thanks!
