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?

Hello,
Some days ago my phone just disconnected from carrier network and now I don't have signal at all. I tried some ftf but with the same results.
The SIM card reader it's ok because I can read my SIM information with the app SIM Info and with the app Network Signal Info I noticed I receive my carrier signal but it shows NETWORK BLOCKED.
I don't know how, but it seems that my phone get locked. This is what I see in SIM Lock:
[] Network 0
[] Network subnet 0
[] Service Provider 0
[] Corporate 0
[] SIM 0
Is my phone locked? How can I unlock it???
Thank you for your help!!

Hi,
Yes, I tried other SIMs in my phone and they don't work. Also, I tried my SIM in another phone and works like a charm.
Thanks!

Hmm...
Well sim lock is possible if developer screws ROM but that's not something that usually happens...
You used AOSP ROM maybe or something suspicious?
Really odd....
And yeah...you had sim locked (branded device) or sim unlocked device?

I haven't use any ROM, just the original FTFs...I haven´t unlock my boot-loader yet.
I have a "unlocked" phone, and it was working fine until some days ago, during a call my phone lost signal.
Is possible to unlocked my phone again?
Thanks!
If SIM info looks like this:
[] Network 0
[] Network subnet 0
[] Service Provider 0
[] Corporate 0
[] SIM 0
My phone should not be locked, right?
Opened a brand new Sony phone, put in Sim Card. After opening Android logo, an MTS logo with blue font and white background pops up. Then it simply states "SIM service provider unlock PIN.
I called MTS in Canada, they have no record of the IMEI number. I called Sony, they told me to **** off 'cus I'm out of warranty. All I want to know is who my bloody provider is, so I can get this thing unlocked. I called T-mobile UK, Verizon, T-mobile US, numerous others and they told me they cannot explicitly state if the phone was ever used with their service.
I am extremely confused, I wanted to use an unlocking site, but alas. I entered *#*#7378423#*#*, went to Service info and then Sim lock. It was as follows:
[] Network 0
[] Network subset 0
[x] Service Provider 5
[] Corporate 0
[] Sim 0
I am wondering if anyone can give me any idea what is going on? My IMEI # has no problems, it is: 35518806-270203-4.
I am not sure how to proceed and get this working. I entered a T-mobile US sim card. Please Help.
#help status of My Sony z3 + Au japan smrartphone signal have not service, what should I do?
IMSI simcard:
[] network 0
[x] network subset 5
[] service provider 0
[] corporate 0
[] sim 0
Is my sim locked?
how to handle it?
Same problem:
My xperia z3+ is losing signal randomly,
it doesnt even show 0 signal bar,
it show blank signal.
No root,
stock rom updated from official xperia tool
(not a rom problem for sure).
Phone opened and signal cable duck taped so it won't move (i thought it was moving).
Signal just drop randomly.
Outdoors or inside some building, it doesn't matter.
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)".
