So, I have an Xperia Z3, D6616, stock, locked bootloader still, and I'm considering sim unlocking the device for use on AT&T. Bought it on craigslist. It's currently locked to T-Mobile. Most unlock websites say not to purchase the unlock code for the device if it is locked to T-Mobile due to an unlocking app that T-Mobile installs on handsets that prevents third party unlocking. See attached pictures. I'm an AT&T customer, so this is a bit of a pain for me.
Called T-Mobile, they will not unlock the device as it does not meet the requirements. I'm not a T-Mobile customer either, so there is no account history associated with this IMEI. I have a feeling that someone bought this device at a subsidized price, sold it new in box, and pocketed the cash. Now I have a fancy T-Mobile MP3 player and digital camera that won't play nice with my AT&T sim....
Has anyone successfully unlocked this device for use on another GSM carrier while originally being locked to T-Mobile without going through the carrier's unlocking process? If so, what website/service did you use? I'm considering selling this thing as it's a bit useless on my network thus far, being locked to another carrier and all.
Thanks in advance.
is this me being a bit daft, but could you not simply put an unbranded firmware on the device via ftf and simply unlock the device via a website?

I'm not sure if that's a possibility. There is no root for this device without unlocking the bootloader, which wipes the TA partition and causes you to lose the DRM keys and cripples camera functionality. I'm trying to avoid unlocking the bootloader for as long as possible, but if unlocking, rooting, and installing a custom ROM will assist in sim unlocking, it may be in my best interest to do so.
I'm trying to do a network unlock with a code and keeping the phone stock if at all possible, at least until a root method without unlocking the bootloader is found, if it ever is... I just need a way to get a code for unlocking WITHOUT going through T-Mobile.
you don't need root to flash an unbranded ftf., once done then simply use a website and buy the unlock code, with the tmobile firmware out of the way there shouldn't be any interference in terms of network unlock.
what i am saying is:
1: flash global unbranded firmware via flashtools with ftf
2: buy your network unlock code
3: enter code as no t-mobile firmware is available on the device anymore to interfere
i am not saying this is possible as i do not have a t-mobile - us device to test, but my vodafone branded z3 has had an unbranded firmware flashed by myself with no root.
i hope this helps clear up any confusion.

I may try this tonight.
If I flash another firmware with flashtool, can I return to stock after unlocking without root access?
Rooting and/or unlocking the bootloader or flashing a custom rom or a different firmware has absolutely nothing to do with SIM lock.
If you try and sim unlock by doing any of that you are wasting your time.
Best bet is to go to your carrier and ask them to sim unlock it

Yeah, that has been my experiences in the past. The carrier always did it for me. But T-Mobile will not unlock this device as it does not meet eligibility requirements, and the unlock websites say not to buy a code for a T-Mobile US locked Z3. I need it unlocked for use on AT&T. I remember unlocking HTC devices with SuperCID and unlocking Samsung devices with dialer codes. Anything like that for the Sony side of the house? this will be my first Sony phone.

Not that I know of. In the UK you can get any phone sim unlocked on any market stall in a few minutes for a fiver. Its not really to do with the phone but the carrier and the laws you have over the pond.
Simply try a websites unlock, I do not believe T-Mobile can block carrier unlocks. Who has told you otherwise?
See the attachments in the OP. The unlocking websites are saying not to purchase the codes if you have a T-Mobile US locked Z3. I don't want to waste $40, especially when there are no refunds, and want to know if anyone has successfully unlocked with a website and NOT the carrier.
D6616 has an NOT unlockable bootloader, so that method is a no-go.
If it was on EIP and they sold it, the phone may be blacklisted by T-Mobile already
I don't believe you can flash a different version firmware, for multiple reasons, one of which is because it's a D6616 and not a D6603
The T-Mobile SIM unlock tool does work if all conditions are met.
Good luck OP, I think you might have a difficult time with this one

Again, the bootloader status has nothing to do with SIM lock.
Flashing another firmware will also not effect sim lock.
I'm seriously considering selling this device and going for another bootloader unlockable handset due to this unlock headache. T-Mobile is no help for unlocking this IMEI.

Sorry for the first line, didn't mean to get that wrong. Definitely agree that bootloader unlock and SIM unlock have nothing to do with each other.
Called T-Mobile again, tried to unlock. No account number to tie unlock request to since I use At&t as a carrier. They recommend I call Sony directly and ask for an unlock. I did, Sony told me to contact the carrier again. I do, and have the T-Mobile rep call Sony guys on a three way call. I explain that I purchased the device on craigslist, not a T-Mobile account holder, I'm an active duty military member, phone was several hundred dollars, I didn't know... boohoo, I'm dumb, I should have purchased from Sony, No moneys to get a new phone since this was so expensive, etc. Sad poor me story, you know.
Sat on hold for a bit, but Sony caved and said they would attempt a remote unlock via code, but it would be between 1-3 days and the reply will be via email. Time will tell, now. Just waiting to see what happens. I hope it works. I had to have the situation escalated to the third level of supervisors to get this far...
sounds like good news, if that fails, you could ask someone you no on T-MOBILE or a family member to give them a ring and pretend its there phone, should also do the trick
That's a good idea!! Thanks for that. I'll find someone at work who has T-Mobile and go that route if I need to.
any updates.. i badly need my T mobile Xperia Z3 to be get it unlocked...
Sadly, there is no update. T-Mobile will not unlock the device unless I use it on their network for 45 days, ahve an account in good standing, etc. This isn't going to happen, as I am an AT&T subscriber. I have the Z3 listed for sale on craigslist. Awaiting a sale or trade. If anyone wants to swap phones for a still in the box T-Mobile Z3, let me know. Looking for an S5, G3, or Nexus 6. Gsm variants only. Too bad, cause I really like the Z3. I would keep it if I could sim unlock.
Is the unlocking app based off the Sim card? Cause I bought my tmo Z3 3 days ago. Used my Sim from my moto x. After I got everything set up I tried the permanent unlock which was successful.
Hello everyone,
This is me posting for the first time here.
I've found a really cheap Pixel 3, but it is carrier locked to a Japanese carrier called Softbank. Is it possible to remove the carrier lock by rooting the phone? If not, what are the other options should I pursue to buy it?
With many regards,
Emir.

If it's carrier locked it's more than likely bootloader locked. If so, you can't root the phone and most likely can't do anything about the carrier lock. You could call the carrier and ask them if they'd unlock it or, That's about your only option I'd guess. Unless you can get in touch with the carrier and get them to unlock it, I'd stay away. Cheap or not, it's not worth a dime if you can't use it after you get it. Just my 2 cents worth.
Hi everyone,
I recently just get my new google pixel 3a from amazon,
but it seems like they send me the Verizon version of it.
The version of the phone is android 10 and I am trying to unlocked OEM under developer options in order to root my device,
but it's likely seems like there is no way that I can unlock the OEM...?
So I was wondering if anyone know the way of unlocking it or maybe there is a way that I can root without Unlocking the OEM.
Thank you!!

Verizon is notorious for locking down their equipment!!! I would recommend seeing if you can return it and get the unlocked variant!

Just a heads up if anyone happens to find this after grabbing the $200 3a from Verizon: they claim they will unlock your phone after 60 days, something on their site I confirmed with a rep. I'll update January 24 if it does or doesn't happen as I plan to root then (for me, a $200 discount was worth a two month delay).

Just so you are aware, the rep is talking about the SIM card lock. This is different than the bootloader unlock which is required to root your phone.
A SIM card unlock allows you to use the phone with other service providers. Most providers will lock the phone as long as you owe money on the phone. If you bought it outright or have paid the phone off, then the provider will generally SIM unlock the phone. Verizon won't even SIM card unlock the phone until it has been active for 60 days. They say this is to prevent pre-sale theft of their phones, but the policy is certainly more strict than any other provider. However do not misinterpret this to mean that Verizon will SIM unlock all phones after 60 days. If you owe money on the phone, they are not obligated to SIM card unlock it. It is possible sometimes to get the provider to SIM unlock the phone while you still owe money on the phone, but that can be hit and miss.
A bootloader unlock is needed to root the phone. Verizon is the one USA service provider that locks the bootloader of all their devices by policy. Even if a Verizon phone is SIM card unlocked, there is no guarantee that you will be able to bootloader unlock the phone or root it. Generally speaking, you should consider every Verizon phone to be bootloader locked and considering it "winning the lottery" if you are actually able to bootloader unlock it. There are times when Verizon messes up the IMEI numbers and allow phones to be unlocked, but that this just luck if it happens.
I've owned Verizon phones before that were bootloader locked and I will never buy another one. But that is my personal preference. If you have no interest in rooting your phone, then the bootloader isn't that important of an issue. But if you do want to root the phone (and it sound like you do), I would recommend that you see about returning the phone during the return period and purchasing the "Unlocked" version (the "NON-Verizon version).
Sic is correct. Verizon will only SIM unlock the phones. That was the main reason I left them back when I had to use rumrunner on my M7. Once it died and I had to get another phone, I left Verizon and never looked back. When they asked why I was leaving, I told them I might return if they ever let us unlock our bootloaders. The employee knew there was no saving me at that point.
If you want to have an unlocked bootloader, the best bet would be to have a non-carrier branded phone.
Does anyone know an unofficial way to unlock this? Otherwise it's going back.
Thanks

Is it financed, or did you buy it outright? Mine is financed, but I assumed (like an idiot, after all this is at&t) that I would be able to unlock it after paying it off. Please don't tell me I'm stuck.
Mine is financed, but I have 14 days to return it. I thought it was a deal at $450, but if I can't root it, I'll have to get an unlocked one.
I'm not from the US but I think people on the OP7Pro would call up and saying there are going on a business trip abroad so could they please have the device unlocked.
It was a bit of a lottery if they got someone chill who would do it. The other option is to pay it off.
That might have been another US network though.

This was the locked t-mo model, and that's how I got mine unlocked. I don't work at at&t anymore but when I did there would be no way to unlock it without it being paid off. However I was contracted to work with at&t and not directly employed by them, maybe someone would have permission to do so I'm just doubtful.

Carrier locked is not the same as bootloader locked. As long as you can toggle the unlock bootloader setting in the developer options menu, you can root. You just can't insert the SIM of another carrier until your device is paid off.
You cannot toggle the OEM unlocking switch on carrier locked devices

It's amazing the number of people who still don't know that carrier incentivized devices are locked and the exploit ship has long ago sailed away into the sunset.

Apologies, no condescension intended. It looks like you've been rooting devices all the way back to the HTC M8. That may well have been one of the last devices that could be bootloader unlocked via exploit. I find it hard to believe that you have been active on XDA all this time and never read any posts regarding bootloader unlocking of Verizon branded/locked devices. The answer regarding bootloader unlock and root has been the same for many years now. Thus my statement that I'm amazed people are still not aware of this.
I didn't know that either. Guess all the phones I've purchased have been unlock devices.. My last phone was a samsung note 10 whick couldn't be unlocked.
if pixel 5 is anything like pixel 4 then the oem bootloader unlock option is tied to the sim lock status. for example my p4 was carrier lock to EE but i paid it off right away so i can sim unlock. becuz i read that once sim unlocked, the oem unlock toggle ungreys itself. this is exactly what happened and i was then able to unlock bootloader.
i read posts about at&t models when early researching the p4 and the way i remember it being explained was it is like apple unlocking system. the serial gets whitelisted for unlocking on google servers which then sim unlocks phone. but this also controls the oem unlock toggle! so basically sim lock status = oem unlock toggle ability status. but again this was for p4.
if youre willing to pay it off early you should be able to unlock. im debating going to p5 because of batteyr life on p4. otherwise love the phone. choices choices! anyway hope this info helps mate, good luck

Thanks for that. Unfortunately if you pay it off early, you have to pay full price (which is somehow more than buying it straight from google). The discounted price only applies if you submit to the 30 month lock in. I returned the phone. Guess I'm sticking with the trusty 2xl for a little longer.
The carrier unlock and SIM unlock are tied together for T-Mobile and AT&T, only Verizon has the "OEM unlock" permanently stuck to OFF and they will not unlock it. I think they need to be pressured but it will take work. They have no excuse.
But AT&T and T-Mobile will unlock the OEM toggle when they SIM unlock, it was confirmed with Pixel 4 when they started selling those carrier-locked. Just usually have to pay off unless you can convince them early.
FYI....T-Mobile only sells the 4a 5G, not the 5. Could change as 5 stock comes back. Short supply right now.
i have no OEM unlock on my A53U T-Mobile Variant, i have tried the date trick, the factory reset trick and still not working.
Any ideas?
You probabaly have US devices and this is why u cant unlock
I don't know enough here but my last Samsung is unlocked US device and it has custom roms available for it without needing anything.
The carrier Samsung devices can have a missing oem unlock that supposedly will show up under the correct situation.
So I'd expect that it can be unlocked. But, I don't buy carrier versions so don't know if its correct that you cannot or not. I just feels incorrect to think that you can't at all and it feels more like its not understood how to get it unlocked.
But, if you can't, you can't. At least it has more updates than Samsung has ever had so far. So you should be happy anyway about that more so than other brands.
