[Q] Xperia TL LT30at with at&t bad IMEI unlocking - Sony Xperia T, TL, TX, V

Hello,
This is my first XDA forum post. And I am sorry for it to be about a trouble question.
I've recently bought a Xperia TL Lt30at that is AT&T from ebay.
Anyway, I am planning on using it in Mexico from time to time, since I live near the border, so I bought another carrier's SIM (Telcel) and was to unlock the phone.
But now that I called AT&T to get the Unlock pin number (for free) they told me the phone's imei was blacklisted.
Questions:
Can I still unlock it to use in Mexico with Tecel carrier even if the IMEI is blacklisted on AT&T?
and, Why after inserting Telcel SIM into the phone the SIM NETWORK UNLOCK PIN screen does not show? Do you know why this is not showing?
Could it be that the blacklisted IMEI is not allowing the Unlock pin screen to show after inserting another SIM?
Many thanks in advance

Thanks for the info. I've already done that and I checked the IMEI number, that is how after calling at&t to unlock my phone they notified me that the IMEI was blacklisted.
The phone has 10 unlock tryouts left.
Do you know if this is causing the phone not to show the SIM NEWTWORK UNLOCK PIN screen after inserting an invalid carrier SIM? Because I can reproduce this from any video I have seen.

no , blacklisted imei is not the reason ; when you insert invalid sim, what is happening? does your phone detect sim and is there any signal?

That is the thing also. I had a regular size SIM card from another carrier, I cut it using a template to fit the Xperia TL that uses MicroSIM (I tested that it still works on phones that use the regular size) and when I place it inside the TL it does not recognize the SIM like it is not there.
Could it be that I need to get a real MicroSIM from another carrier to display the SIM UNLOCK NETWORK PIN screen?

yes of course, you need good micro sim card, phone does not detect sim card because it is not well cut; if the phone works perfectly with other sim it means that there is no damage to sim slot; i also have got xperia lt30at; I cut micro sim using template and it worked fine; when there is no sim card detected, the SIM UNLOCK NETWORK PIN screen will never appear

Thanks for your help, I have gotten a new microSIM from my carrier and it works. Seems the other one was very old and not even cutting it would have worked.
Now it does display the SIM UNLOCK NETWORK PIN screen after inserting it.

Yo don't know if you unlocked it yet but I just unlocked one for sell n it can't be blacklisted cause all the networks have the imei number n it won't allow the phone to work?

Imagio sim card master confusion....

I called VZW and got my unlock code, and I have unlocked it so that I can use another Sims, but while the other Sims is on the phone, or even without a Sims card I can still make phone calls. This is a problem as I unlocked the phone so that I could use Sims on India, where I'm traveling in 2 days...tips?
A call to VZW clarified my questions. While on CDMA inside USA the phone does not use the SIM card, with a T-Mobile Sims card on the phone, I switch to GSM and the phone inmedially registered the T-Mobile card and new number. If I happend to be abroad, and I have my Verizon/Vodaphone Sims inside, the CDMA network will then use the Sim to register on the network.
Learning learning...
Unlock?
So how does Verizon give out this unlock code? I have an Imagio but I whodinied it and have it on metroPCS. I would like to unlock the phone to use AT&T or T-Mobile.
Call global support and tell them you will be going overseas. They give you the 8 digit unlock code, you enter it. Poof. I can use my neighboor's AT&T SIM and be her .
You do not need the SIM in the US to make calls on Verizon.

Even if I don't have the Imagio activated with Verizon? Is the password different for each phone? How do you enter this password? You dial it in?

Yes they are all different, they generate the code from your IMEI ( kind of like a cars VIN number ). *#06# will give you the IMEI.
Just tell them you are going abroad and not using Vodafone and that's it. 800-711-8300 Option 2.
IMEI is under Start/Settings/System/Device Information/ Version Tab
You enter the 8 digit code under
Start/Settings/Personal/Security
Good Luck!
They denied it, they said I needed to have the $29.99 plan plus the $39.99 unlimited data plan. WTH???
Any other alternative?

*#06# didn't do anything, even tried the "TALK" afterwards, nothing, nada.
Any other trick in getting the IMEI?
Who did you buy it from, who is your carrier? You probably should call your carrier if Verizon won't help you.

I figured it out, had to switch to GSM mode before dialing the *#06#
Im boricua also, and have the Imagio on metroPCS, trying to get GSM working when I go to PR I can call out with same phone.
You *DO* have to have a qualifying Verizon account. I asked and the minimum account you need is the $29.99 and you also need the $39.99 unlimited data plan addon. Too much IMHO. If you have the Imagio on another network (like I do) then here is a service which is in our pocket's reach...I submitted my IMEI and will post results as soon as I get my unlock code.

Hey would you please help me whodini my hTC Imagio to cricket as well?
PLEASE
LOL! Whodini is a metroPCS flashing tool, not sure if Cricket uses the same software. Try calling Cricket to see if they will add the MEID of the phone to their network or if you actually have to take it in to one of their stores to have it done. I can guide you how to provision it once the MEID is on their netowrk...
I am looking for the data settings for T-mobile. Can anyone help?
While I was abroad in India, I used my company's T-Mobile Sims card, from which I send SMS and also used voice but no internet as I had my data OFF, what I did not know was that they still charged my Verizon account 16 bucks of data fees. Apparently since the phone is global it still was recognized on the India network as it was trying to connect to their network, in other words, just the fact that the phone was trying to connect to their antennas counted as data transfer!!! I rather pay for unlimited international data plan next time I'm abroad and it would have being the same amount of money...sucky

is there a way to unlock tmobile xperia z?

I have an xperia z c6606 by tmobile. Im trying to get it unlocked so my gf can use it from at&t or another gsm carrier. Is there a way for me to do this?
Ps: i tried putting the att sim card in, but then it asks for a sim pin which was never set up to begin with. So i guess it locks the sim because the phone is locked?

Request the service provider for the unlock key if you have completed the contract obligations
With T-Mo they should do a sim unlock after 45 days of service with them.

Help N-920C Region lock or Network lock

N-920C Region lock asks for Sim network pin.
I purchased Note 5 model N-920C from Saudi Arabia but when I came back to India with an Indian simcard it asks for Network Sim Pin and if I discard it says invalid sim card or network locked sim card inserted.
Can anyone please help..
Thanks in advance
i have the same prob... anyone pls help
Saudi phones are region locked to prevent theft and black market sales. In order to unlock it you should insert a Saudi SIM like zain, stc or mobily and place a 5 minute call (whilst in saudi).

I bought my phone too in Saudi online but my sim works from my country in Philippines.. I did some tweaks on my phone but when I flashed a stock rom, it now asks for a network pin unlock ?. Help! (I don't know how to start a thread ?)
You have basically 3 options here to get rid of the region lock.
1. get a SIM from the country the phone originates from. Make a 5/6 min call to a mobile number. That should remove the region locking after this you should be able to use any SIM you like.
(note) You must call a mobile number from the phone and NOT a landline. And secondly if You do this procedure from outside the home country of the phone that call will be considered to be a roaming call and will cost more than a regular call.
This procedure is intended to be done to activate a phone with a local SIM while STILL in the country of origin and may NOT work if the phone was NOT activated with the original SIM of that country. It may be possible to still make this work by performing a factory reset and using the correct countries SIM card and performing the above procedure.
2. Look for one of the many phone unlocking web sites that offer a regional unlocking code and buy that code. (Note) the region unlocking code and the network unlocking codes are NOT the same thing so even after you have gotten rid of the region lock you may still have to get a network unlocking code if the original network operator has locked the phone to their network.
The code you need is the RGCK unlocking code. You maybe able to also get this code from the Samsung agent for the region the phones is from.
3. Speak to Samsung for the region that the phone was sold and intended to be used in. You maybe able to also get the RGCK unlocking code from the Samsung agent for the region the phones is from.
(note) this option will may require that you return the phone to Samsung for that region and they can remove the lock. This is likely the most costly option.
I hope that this info is of use to you guys.

Pixel 5 sim lock or mobile connection not working?

Have an used Pixel 5 here which was labeled as sim locked (carrier unknown ). I'm not sure if it really has sim lock or if the mobile connection is defective. When I insert my SIM it asks for the PIN and then the correct carrier is shown under network settings - there is no signal however.
How can I make sure it has sim lock and it's not a HW defect?
If it's locked - is there a way to find out the carrier which it is locked by?
More general - how is a sim lock indicated to the user when inserting a sim from another provider?
I've sent the phone to google for repair (Connectivity problem). They stated that no defect was found which would support the sim lock theory. Is there a way to know for sure?
If Google Repair team says there are no defects (assuming the team that handled it were competent), then it most likely is a carrier locked phone. I've never used a locked phone before so I'm not sure what to look for but if you can find out which carrier it's locked to, you could try inserting that carrier's sim card?
If you get a signal, then swap out the sim card to a different carrier and if it doesn't work, then it's definitely locked.
I don't know which carrier it could be looked to and how to find that out. When I enter the IMEI at the start of the repair process in the google store the device is identified as "Pixel 5 (128 GB, Just Black, without SIM-Lock)".
