[Q] How come my O2x is unlocked? - LG Optimus 2x

Okay, so I'm pretty sure when I bought this phone with contract it was network restricted.. I changed my carrier yesterday to t-mobile, so I bought a sim unlock on the net. I received the SIM unlock code, I couldn't get to the input field though (I'm on CM10), but then I was playing with settings and I could successfully connect to T-Mobile, however the signal is weaker than it was before and it has disconnected twice, but still.. so I don't need the unlock code no more am I right? It was cheap so it doesn't matter, I just don't understand how can this phone can be unlocked.

Just curious, what was your original provider? I don't know specifically about T-Mobile, but some carriers allow other SIMs to be used, because they are sharing networks. For example, if you have a locked Rogers phone in Canada, you can use it with a SpeakOut SIM, because SO is riding on Rogers network. Could it be a similar situation for you?
But it's strange that you don't see a prompt for a network lock code when you insert a non-original SIM... I also had to unlock my phone by code, and I got the prompt right after putting in a different SIM. Could it be because you are on CM ROM? A general recommendation is to always unlock you phone from a stock ROM, before flashing a custom one. I am not sure about this, but just thinking out loud...

I was on Telenor Hungary, now it's T-Mobile, they are whole different providers, no relations at all. Well yeah, I've thought about that stock ROM thing too, but I still don't think it would connect to a different carrier because of the custom ROM. But it works strangely though, couldn't set up mobile net yet, and when I was on the T-Mobile hotline, it disconnected and the phone said the SIM might be corrupted.

So I tested, I can make phone calls, but everytime I reboot the phone I have to connect to the network manually from settings.. So I'm gonna try with stock ROM, and use the sim unlock code. Can I also use stock-based ROMs? Thanks.

Is the phone sim unlocked? I don't know how it works with Sprint but that would be the case with GSM providers
If it's Sprint, it's CDMA.AT&T and T-Mobile are the only GSM providers in the US. However, it should work there if you get the SIM unlocked. The SIM unlock code is formulated based on the IMEI, so there are three ways to get it:
From Sprint. Probably the simplest, but tricky if you're not the phone's original owner.
Pay a site or unlocking service with the algorithm that decodes it from the IMEI. Usually runs around $10-$20.
Try the steps in this thread:

You can also try this app, but it only works on rooted phones running the original ROM:

Good luck.
How do i go about unlocking the Sim? I cant get the unlock box where I put in the code to come up!

Bro, A CDMA PHONE CANNOT BE UNLOCKED. IT WON'T EVEN WORK ON ANOTHER CDMA CARRIER LIKE VERIZON. ONLY SPRINT SIMs WILL WORK.
Make sure u buy a GSM phone if u plan 2 use it on another carrier.
But the phone uses GSM! It picks up the network here but I just cant get the unlock box

Then it simply isn't a Sprint handset. CDMA phones can only work on that particular network. The phone is custom-made just for that network

AT&T unlocked 2014 x not working on tmobile

I have an unlocked AT&T xt1097 but it won't register my T-Mobile Sim card. It registered for about 3 minutes, got a welcome to T-Mobile text and that was that. My phone number shows up in settings, but it shows I have zero service. I've reset, and rebooted several times to no avail. My sim works in a nexus 6 so it's not the sim. Imei os clean. Does anyone have any ideas what it could be or how I could get it to work with my T-Mobile sim?
When you say unlocked, unlocked Sim or unlocked boot loader?
sim unlock. As far as I know there's no boot loader unlock.
Could it be that the imei isn't in T-Mobile's data base since it's an at&t moto x?
Edit: went and put the imei in to tmobiles imei checker and it couldn't figure out what device it was and if it was okay to use on their network. Now I just need to verify with T-Mobile and see if they can register the imei.

did you ever get it to work? i am experiencing the same issue. it connects to my friends AT&T network fine but with t-mobile it just says "cant register" etc,etc.
Change the APN settings
I have had a problem like this with my unlocked phone and AT&T, but when they set it up in the AT&T store they fiddled with the APN settings. I had to do the same to get my wife's unlocked Lumia 635 to work on the T-Mobile network. Try the values used in the link attached and see if it works.

I was able to connect to tmobile network some times, able to make calls. No data connection at all. I played with APN settings and everything else. any help..?
I have an unlocked ATT x1097 and it works just fine with tmobile.
You just have to MAKE A NEW APN SETTING.
When you put a tmobile sim in it, it will automatically create a couple of T-MOBILE apn settings. Just leave that as is and create a NEW APN SETTING with same info you can find from Google. Select that as your data apn. And reboot the device for the best result. It should fixed the problem.
For those of you whose sim does not register into tmobile network; i think it could be one of the following reasons:
1. Original ATT modem does not work well with tmobile frequency in your area
2. The device is locked (stolen, non-payment, etc)
3. The device is broken
4. Your SIM card is damaged
As long as you are at the home screen with tmobile sim, your phone is GSM UNLOCKED, and it iwill never lock again.

Just wanted to say thank you. My T-Mobile SIM wouldn't connect and I even went to the T-Mobile SIM store to get a new SIM Card but it didn't help. As you stated, adding a new APN setting was the only thing that worked.
For those of you who want to unlock your Moto X, I purchased a code on eBay for about $8 and received it within 6 hours. I would post the link but I'm afraid it might be considered spam.
What type of data signal are you getting? LTE?

Nice. Where did you get your unlock code?
I don't know about OP but I have always used swiftunlocks and have had great luck. Got my N6 from ATT unlocked through them without issues as well.
http://www.swiftunlocks.com/unlock/motorola-at-t-tmobile-worldwide
I noticed that sometimes phone picks up apn without issues and sometimes you have to restart so I just restart every time I make a change to be on the safe side.
Just in case anyone else has the same issue as OP, you should use the
Code:
epc.tmobile.com
APN, NOT the
Code:
fast.tmobile.com
one.
The fast.tmobile.com one would not let me register on the network. epc one did immediately.

Hey, I know this post is kind of old but I am currently having the same problem with my moto X 2014 going from At&t to T-Mobile, were you able to get it fixed and if you did, what did you do?
Any luck? I've just come accross the same issue. Got phone unlocked, and bought a new sim and activated. I'll get like 3-4 minutes of service randomly here and there, but about 99% of the time no service. Tried multiple variations of APN settings that I've found online. No luck
Fixed all my seriously annoying connection problems by flashing the 4.4.4 modem.

Neither one works for data... Just got it unlocked from swiftlocks and I can get voice, but no data :crying:
Someone help!! ...plz
Anyone ?? T-Mobile reps are mostly useless, and keep telling me that my device may have been ' re-locked ' to AT&T after a hard reset !! I know that's not the case because I've thrown in a Vodafone sim and it recognized it ! The sim unlock was purchased from SwiftUnlocks and the phone took it in one try w/o any issues!
Now, I can't even get voice to work... All I see is ' No Service ' and when manually trying to register with T-Mobile, it says ' unable to connect to the T-Mobile network. Please try later '
Someone please help out!!

[Q] Unlocked Moto X on Telus/Koodo Issues

Hi I bought an unlocked, Verizon branded Moto X Developer Edition which I intended to use on Koodo in Canada, which runs on the Telus network. When I put my sim card in it has trouble connecting to the network. It connects for a couple of minutes, and then loses the signal for a couple minutes, then picks it up again and so on. It's like it is connecting to cell towers other than Koodo/Telus and cant use them.
I have tested the sim card in another phone and it is fine. I have spent a significant amount of time with Koodo customer support and it has become obvious the problem is with the phone. It doesn't matter if I have it set to global or LTE/GSM and connect to Koodo that way, both have the same result.
Has anybody run into a similar problem? I absolutely love the phone and would hate to find out that I can't use it. I live in London, Ontario and shouldn't have any issues with coverage.
Thanks
I have The exact same problem with a moto X from ATT trying it on Koodo. Maybe flashing the Telus rom or dev rom on it could work. Mine is in 4.4.4 with ATT so I can't unlock the boot loader to do that but maybe you can...

Have you tried manually entering the APN settings?
The Verizon XT1060 (Dev Edition, or non-Dev Edition) is SIM unlocked out of the box. So forcing to GSM mode should work, as long as the APN settings are right.
As a side note, to use a T-Mobile USA Sim, I've had to manually enter the APN settings on my Dev Ed VZW X.

U.S. Galaxy Note 4 on Wind Mobile in Canada: Can't Connect to Network

1) My friend (U.S.) gave me (Canada) a T-Mobile Galaxy Note 4. I am trying to use it with Wind Mobile.
2) He claims that T-Mobile performed a carrier unlock, which seems to be confirmed because putting a foreign SIM card in does not ask for an unlock code.
3) My Wind Mobile SIM can't register on network. I tried a Rogers SIM as well and a different Wind Mobile SIM and they didn't work either.
4) The Wind Access Point Names have been entered, but manually selecting the network does not work either. It just says "Unable to connect, try later".
Am I missing something here? Is there another type of lock I need T-Mobile to remove? Do I need to flash the ROM? Thanks in advance.
If same sim cards work in other phones i would think that phone is blacklisted. On the other hand nowadays tmobile can issue temporary unlock codes for international travel. I dont know if Canada is considered international or not. Tmobile will permanently fully unlock device when paid off.

T-Mobile Revvlry Plus XT1965-T: About Network Unlocking (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+

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.

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.)

When I go to the menu: "Settings > Network & Internet > Mobile network", all further options are grayed out.
As such, I am not able to reach the option: "Settings > Network & Internet > Mobile network > Advanced > Network Unlock > Permanent Unlock" as shown at the link you provided.

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.
