Sony Xperia T Sim Unlock

Dear,
I will become owner of Sony Xperia T but from another operator who I using now. So my question is, does anybody know how to make Sim Unlock without rooting and flashing it?

2015- Still no engineering for Bootloader Unlocking?

I own the Xperia SP since 2013. I recently got a Galaxy S6. The issue with the Xperia SP I had was like many others, even after Carrier Unlock, the bootloader unlocked allowed remained No. Hence I was very limited to the ROMs I can use. We don't even have Lollipop stable enough for daily use. UBL right now has Marshmallow and also Cyanogenmod Nightlies which I would like to try out on my Xperia before I root my Galaxy S6.
So do we have any updates for SP users to be able to unlocked the bootloader? I mean neither Sony nor carriers support the device anymore, they should allow us to play with it now, no?
Please post any updates here

i agree they should tell us how to unlock it as no -one supports it anymore

I read somewhere (i realy dont recall where) that sending your phone to sony so they can unlock the device for you. is possible.....

Any news ?

Greetings friend,
I've personally emailed Sony asking for official way to unlock bootloader of my LT29i.
Unfortunately the reply was unfavourable , this means we'll have to unlock bootloader using unofficial method.

Hi buddy, I've verified that by selecting Xperia T in the Sony Official Unlock Bootloader link is working on Xperia TX as well as long as the IMEI you provide matches your device (selecting Xperia V may also works). Now my bootloader is unlocked. :fingers-crossed:

They are the same phone, actually

I take it there isn't a fix for this presently? with a OS downgrade or otherwise? the Z4 can go down to Android 5.0 with official firmware.

Unlocked my SOV31 (au Xperia Z4) with the qUnlockTool (s1 network unlock tool) and this changed my "bootloader unlock allowed: no" to yes. I got the software and login credentials from a UK eBay vendor. If anyone runs into this information I hope it helps, took me forever to dig through threads on XDA/Reddit/GSM-Forum.

I need answers.
