I think the lt30a is the AT&T phone. You may be able to get an unlock code from them. I had no problem getting an unlock code from AT&T when I sold my S3 to buy this phone.
EDIT: I read this wrong. the AT&T version is lt30at. Sorry.

yes.
from what i undestand it was bought in uk.

some people are confusing the 2 unlock types
Just in case, the sim unlock process is a simple one, just insert another sim from the other provider and enter the code provided.
Unlocking the bootloader is not possible with some versions including the lt30a - at least a method does not yet exist - unless you are working with the models that have unlocking enabled. Check other posts which cover this topic extensively.

yes i know it asks for the SIM network unlock PIN, i do not have one.
and also i know that the bootloader isn't unlockable, i've checked in service info. i don't need unlocked bootloader for now as i have rooted the latest stock 4.1.2, only problem i have it with the sim lock..

got the sim network unlock pin from network operator, thread can be closed

Or put [solved] in the title
Sent from my LT30p, 4.1.2 stock, DooMKernel v7,root access, unlocked bootloader.

Unbranded from 3 network (bootloader unlock allowed no)

Your phone is locked to a carrier. To use it on another carrier you have to get an unlock code.

[Q] Unlocked xperia Z1 network locked because of flashing Branded Firmware

i have a Sony Xperia Z1. the model number is C6906. i bought it directly from Sony and its Unlocked . it was working on every sim card. But i flashed the C6906 firmware of the other branded network provider. now it's network locked with that network provider. it only works with the sim card of that network. when i put any other sim card, the dialog box appears and it tells to insert network unlock code. when i contact that network, they told me to get their sim card and use it for 90 days. then they will provide me the unlock code. why should i have to use their sim card for 90 days to get the unlock code, because my phone is already factory unlocked from sony. i went to 3rd party websites which provide network unlock codes. but they didn't find the unlock code for my phone, because that phone is not present in the database of that network provider. that means i can only get the unlock code from that network code by using their sim card for 90 days. but that network is not working in my area. please suggest how can i make it unlock again as it was before ? i will be very thankful

flashing FTF files will not affect the SIM lock status of a phone.
It will neither lock an unlocked one nor will it unlock a locked one.

i flashed the firmware of Rogers for my unlocked xperia z1 C6906, which was Branded Firmware. my phone was working fine with all sim cards. but few days ago i put the sim card of rogers, the phone automatically restart and also install some rogers network apps in phone menu. after that when i put other sim card, the network unlock code dialogue box appears. it means that phone got locked with rogers now. the rogers technicians said me if you flashed rogers branded firmware, then if you ever put rogers sim card in it, then device will locked to rogers even if its unlocked from sony.

well, not sure how that works as its the first time I ever heard that happening. Not that I don't trust operators but I often find they do not know what they are talking about when it comes to the kind of things we do here at XDA
But, if what you say is true, flashing another FTF will NOT help.

can xda developers develop any software for that ? so that the network unlock code dialog box disappear and phone reset with original factory unlock setting

that is not really what we do here. there are loads of websites for that, and rogers say they will give you an unlock code in 90 days anyway.

[Q] [Help] Sony Xperia V SIM Unlock

Hello ! Been browsing xda for few years and found a lot of good info here , keep up the nice work. But now i got some issue and i cant find anything to solve it , maybe some of you could help me.
My problem is that i recently bought a Xperia V, was bought i think from JAPAN , on the top writes on it NTT DOCOMO - has a locked SIM card.
What i tried -
-unlocking bootloader with official sony guide , but if i type *#*#service#*#* says to ROOTING STATUS - BOOTLOADER UNLOCK ALLOW - no, anyway to the SIM LOCK - [x] Network - Unlimited , this means i got unlimited tries to the code it locks it ? still didnt found a way to unlock bootloader
-rooted phone, installed custom recovery
But still havent manager to get rid of that simlock , everytime my phone boots up asks a NETWORK SIM UNLOCK PIN.
Status
Model LT25i, Android Ver. 4.3, Build No. 9.2.A.2.5 ( ask for more info if needed )
I can downgrade to any version using flashtools.
Anyone can guide me if is there anything i can do ?

network locked

Hi, i changed my c6903 from 5.1 to 4.4.4 and than needed to change it again to 5.1. I don't remember but one of those roms was German.
Problem was that at some point my device was giving me some notifications under lock screen that it might be network locked ro something.
I don't have sim tray because i was using it like tablet.
Is it possible that it could get locked just by puting German rom and if there is a way to check this and to fix this????
Service told me it would cost me 40€ to unlock it if it's locked.
