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

hello;
insert at&t sim card, dial *#*#7378423#*#* after this there will be several options shown, choose "service info" and then "sim lock" , there will be listed 5 things , first one is "network" , if you wanna know if your phone is at&t locked, there should be 'x' between [ ], like this [x] network and the number, maybe 5,4 or three, this last number shows the attempts left for network unlock; if there is no x between [] this means that your phone is unlocked for all carrier ; if there is x between [] and last number id not 0, you can unlock it! just search by google ,there are several websites which offer unlock codes for amount of money, you only provide imei code , and they generate code" to see imei , dial *#06#;

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?
Sent from my SAMSUNG-SGH-I337 using xda premium
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.
Hello,
I have just acquired a new (never used) T-Mobile Revvlry Plus XT1965-T, and it seems to be network locked. (Note: I was able to get an OEM unlock code from Motorola, haven't tried it yet, but right now I am only asking about the network lock issue.)
My goal is to install LineageOS 18.1, and use this phone with other mobile service providers in Canada.
I want to understand how to deal with the network lock, and get past it -- I have some questions...
1. If I simply follow the official instructions for installing LineageOS, will this result in a network unlocked phone?
2. If just installing LineageOS won't remove the network lock, why is that? How is the network lock implemented on this phone?
3. Is there any way to clear the network lock, without going through T-Mobile?
4. If I must go through T-Mobile and use their unlock app, I assume that I had better do this before I do anything else, and once the phone is network unlocked using T-Mobile's app, then the phone will remain network unlocked after installing LineageOS, is this correct?
5. I get the impression that there are actually two different phones with the same model number XT1965-T, being the T-Mobile version and the Motorola version, is that right? What are the main differences?
Any other comments, insights, or links are also appreciated. Please keep in mind that while I am highly technical, I am not an expert on Android or smartphones.
Thanks.

1. No, network lock is related to the carrier. If it's a TMO Revvlry+/Revvlry Plus, then it's locked to T-Mobile. This means it can't be used with another carrier essentially. Network lock again just means if a TMO sim is installed (and it's locked to TMO) it will work. If another carrier sim is installed and it's network locked, the sim won't function.
2. If the phone came from TMO, they would lock it to their system.
3. Removing the network lock allows other carriers to be used. There are pay to use services that will network unlock the device within 24 hours. Manual methods exist, but will require more in-depth knowledge. Otherwise, TMO is the one to network unlock it but could take 30 days and may require service with them.
4. Once unlocked it should remain unlocked, regardless of stock or custom ROM.
5. The TMO Revvlry+ (Revvlry Plus) and Moto G7 Plus are the same devices hardware wise. The main difference is the boot animation and logo branding. The Moto G7 Plus is also carrier unlocked.
How did you determine the phone is network locked?
Is the phone tied to a network carrier already?

Thanks for your reply, here is some background...
I bought several of these phones on eBay, they were advertised as network unlocked Moto G7 Plus phones, but the seller instead shipped me network locked T-Mobile Revvly+ phones.
My first step was to test a SIM chip from a local mobile provider, and the phones show a message saying they are SIM locked.
The phones are clearly new and unused. The seller claims they are open-box returns.
I called T-Mobile, and T-Mobile says these phones are registered to active accounts, and they can only be unlocked if the account holder requests it. T-Mobile reps also say they are unable to identify the account holder, and offer no solution. The phones are not blacklisted or reported stolen. If I had to guess: most likely, the phones were purchased, activated, and returned to the store, but the T-Mobile account registration was not cleared in their database.
It seems that these phones use an unlock app, rather than an unlock code, and from what I've read, it may not be possible for any third-party unlocking service to unlock these particular phones.
Getting back to my questions in my original post:
- How is the network lock implemented on this phone? (I mean this question from a technical perspective)
- Is there any way to clear the network lock, without going through T-Mobile?
The network lock must be a setting somewhere in the firmware... I've heard people talk about flashing the baseband, but not being a phone expert, I don't know much about that, or if it might apply here...
So again, I am asking: is there some way to network unlock these phones, and make them usable with another service provider? Can I somehow just reflash whatever area in the phone holds the network lock setting with stock code that doesn't have the network lock setting enabled?
Thanks.

If they are registered and active, they may have to wait out the time period from T-Mobile to be Network SIM unlocked, depending on when they were originally purchased by the original owner.
If they were returned to the store, how did the eBay seller obtain them?

If an unlock app is needed, this may be built into the phones firmware that only T-Mobile can use. It may still require a code to be passed to the unlock app.

It's implemented by T-Mobile. T-Mobile is going to be your best shot. You may have to make multiple calls to get through to someone where you can explain the situation and see if they will network unlock the phone.

Baseband typically indicates the frequencies the phone can use to communicate with different networks. If you take a nandroid of the phone, you can always try to flash a new baseband and test. If it doesn't work, restore back.

You can try to flash the T-Mobile Revvlry+ into a Moto G7 Plus: https://forum.xda-developers.com/t/revvlry-to-moto-g7-plus-conversion-guide.4136355/ That would get rid of the T-Mobile software. It's not clear if that would remove the network SIM lock, but if you take a nandroid backup, you can always revert back.
EDIT: I was doing some additional research, and flashing the modems/baseband or converting the TMO Revvlry+ to Moto G7 Plus won't affect the network SIM lock. The app is in the TMO software and you'll have to use that app with the code either TMO provides or an unlock service gives to network SIM unlock the device.
EDIT2: After booting into the phone, do you have the options in the following settings: SIM unlock phone. This link is only for info and reference: use any network provider’s SIM card in T-Mobile REVVLRY+
Hi, thank you again for your reply.

As mentioned, the phones are clearly brand new and never used.
I would also like to know how the seller obtained them, unfortunately the seller is non-cooperative.
T-Mobile is also curious about how the seller obtained them.

I may try this again, but I have already spent hours talking to T-Mobile Technical Support with no progress made.

I am still not clear as to why the phones can not be unlocked by replacing certain firmware/software. The lock is a setting somewhere on the phone, why can this setting not just be manually changed/cleared?

When I go to the menu: "Settings > Network & Internet > Mobile network", all further options are grayed out.

Any further suggestions/advice much appreciated, I would really like to be able to make use of these phones.

The app is provided via TMobile. This is not provided via software/firmware except by TMO.
Your best bet at this point is to try a pay to unlock service that will provide instructions on unlocking the SIM, if TMO is unwilling to do it.
(Modems change the baseband used by different providers so changing/updating it via firmware isn't going to unlock the SIM/Network. If you get the SIM/Network unlocked and THEN have an issue with a network carrier, flashing the correct modem for that provider would allow the SIM/Network to communicate.)

Do have service with TMO? If not, you might try getting a SIM/Network card from them and inserting it to see if the in-phone options appear so you can unlock it. You might also try escalating the issue with TMO if you are only getting to first line technical support personnel.
The phone is obviously locked to TMO as it's a TMO phone. It's different than the Moto G7 Plus which is already unlocked for all carriers. If you can't get the phone Network/SIM unlocked, maybe return it to the eBay seller and look for the Moto G7 Plus which will give you less headaches.
