I got the 'STRING: NOT FOUND' error on method one, so I moved to ADB Guide method and successfully unlocked it.

If you unlock the phone, it will still work with the original SIM card.
One possible reason that the other T-Mobile SIM didn't work is that it might not have been a newer 4G-capable SIM card, or the contacts became dirty ( they can easily be cleaned with a pencil eraser).

Did you try inserting "a SIM card not attached to your current provider (e.g if you have T-mob use an ATT SIM CARD) and turn on your phone?" (credit sanfranx415 post) edit: maybe try a different gsm carrier in the same country you reside.
From what I have read and understand different versions of busybox will work or are compatible for different things (maybe somebody will tell me if that is not accurate).
Here is a video that might help.
Good luck!

Try contacting t mobile and tell them your going overseas for a few months and want to take your phone with you and is there a way to unlock it so it can be used in another country.

When you insert the sim card and power up the phone, as you unlock it it should give you a network lock screen that only lets you use the phone after inputting the unlock code.

No the phone is unrooted and running isc 4.0.3 but the question is how to enter the unlock code without the phone asking

How many different carrier sims have you tried? Some carriers use the same carrier code and as such there sim will not prompt you for the code. Like in the UK giffgaff and tesco mobile run on the o2 network. And as such do not require the sim unlock to run on an o2 locked phone. Try as many as you can find from different carriers. And if that fails, and it still doesn't give you the prompt, you can s-off the device, and then follow the sim unlock guide by viper (I believe) and do it for free

[Q] Sim unlock - network unlock

Hi All,
Is the network unlock by flashing modem (http://forum.xda-developers.com/showthread.php?t=2022296) same as sim unlock?
If not how one can unlock the phone having root and bootloader unlocked but not calling my carrier and asking for the code (I've still wait another 4 months to get code from them)? The phone is locked to French SFR.
At the time I've had Neus One, if my memory serves me right, at the time of rooting the phone it was sim unlocked as well.
Thanks in advance for any advise.
p.s. should this thread be placed in different sub-forum, please move it. Thanks.

There are 2 types of unlock:
1) Network unlock = Will allowed your phone the usage of other carriers services, then your own SFR (can use other networks sim cards)
2) Bootloader unlock = Will enable your phone of installing custom or other carriers ROM's
You can root your phone without any type of unlock = Root will enable your phone to install the recovery apps..& others apps (not ROM's)

How can I do network unlock without calling carrier (SFR) and without paying for the code? Can it be done via flashing modem or any other trick?
So far I'm on the binaries provided by SFR, original ICS and then upgraded through OTA to JB.
Thanks.

Where?

Accordingly to the Forum Rules I can't advertise any product or services. Google on line & there are plenty unlock services.

Which version of the phone do you have? The Verizon branded versions **are** SIM unlocked, though they don't work on ATT/TMobile in the US. Furthermore, they don't work with a foreign SIM in the US.
However, if you take the phone abroad and pop a foreign SIM in it, it will work. How do I know this? I'm sitting in Australia on Optus/Australia as we speak...
So, if you have the VZW version, no code is needed.

The law in France changed a few month ago, you just need to wait 3 month and sfr must give you the unlock code. Not 6 month anymore.

[Q] Sony Xperia U network unlock

It's probably a n00b question so apologies in advance, but if I root / bootloader unlock and Cyanogenmod flash an Android phone that's locked to a certain network, will that network lock be removed along with the official default Android ROM? Or is the lock at something like a BIOS level (or whatever the smartphone equivalent of a BIOS is)?
I bought a pre-unlocked Xperia U about a year ago that I've been using on Vodafone and had to return it under warranty (got stuck in a boot loop despite the fact that it's totally unmodified, not even rooted, honest!) and the replacement they sent back is locked to Virgin Mobile. They're telling me that the phone I sent them was originally sold to Virgin in France and locked to Virgin before I bought it, and that they've therefore fulfilled their responsibility. So I'm just wondering now about unlocking, and I've always been curious anyway about how / if bootloader unlocking, custom ROMs etc are related to network unlocking.
Thanks in advance for any help you can provide with this!

well u can unlock it.. by getting the code from sony..
It will also unlock the ph..'s Sim lock..
Or ask the sony officialy for this.. they'll provide u every info required.
But unlocking the bl will do the job for you to be sim free
But do double check this from google too.
Also before unlocking pls make a backup as it will wipe everything from the device.
Just unlock and don't flash any custom kernels.If you want to then do it carefully pls with a backup and a copy of flashable stock rom.
Flash custom roms based on stock kernels
Hope this will answer the query..

Thanks for your reply! I spoke to Sony and they just told me to contact the network (which have done and they're wanting to charge me a fee to provide the unlock code). So to clarify, if I root the phone and unlock the bootloader, the network SIM lock will also be removed?

Not by rooting but also i guess not even by unlocking bl..
how much are they charging exactly..
i'll try to find the link for this
Also check this that how many times is the code applied for unlocking..it should not be 0
use this *#*#7378243#*#* in dialer
then service info sim lock

When I dial that number, the number just disappears. What is it for? They want £15.32 for the code. Should I just pay them and forget about trying to remove the lock?

Sorry the code is this
*#*#7378423#*#*
check the sim lock counters should be zero in all..
if zero then once u can try googling the code for unlocking if they work then it's great.
if not then it would be better to pay them for this as its a bit risky..
and are u using virgin's network??
As it's cheaper what they areaskingfor i guess.
