I am moving to Taiwan next month and I wanted to unlock my phone to be able to use SIM cards from their carriers there. I am planning to call Sprint to have them do it for me OTA but I just wanted to check on a couple things first.
1. If I decide to install a custom ROM after Sprint does the SIM unlock, will it "break" the unlock? I'm not exactly clear on what controls the locking of the SIM card so I just want make sure I know what to avoid doing to my phone in order to keep the phone unlocked for international use.
2. If I cancel my Sprint service and only use the phone on an international carrier will the SIM unlock stick? I'm assuming it would but I just want to make sure because of my ignorance of how this whole SIM unlocking thing works.
Thanks in advance, any insight about this topic would be greatly appreciated!
The ssu app will work if your on KK.
Once it's unlock it stays unlocked.

Thanks for the link! I think I'll try going the free route first and have Sprint unlock it for me. If I end up running into any problems in the future with flashing ROMs, it's good to know that there's an app I can buy to keep it unlocked.

I successfully rooted my Atrix but since my volume up button does not work I cannot unlock it. Is there another way to unlock this phone without paying for unlock codes? I have read where at&t will give out the codes for free. Will that affect my account with them? Sorry if these questions are common knowledge but I am a newbie at this and anxious to check out some other roms.

I think you are confusing unlocking the boot loader (to install other ROMS) with unlocking so you can use other carriers besides ATT. You can buy unlock codes on ebay for 99 cents. This will enable you to use any carriers SIM card. That is where I purchased mine.

Yes, you are absolutely correct. I am confusing the two. What need and want to do is to unlock the phone so that I can unlock the bootloader and experiment with various roms. Thanks for clearing that up for me.

ok thanks,i will give thanks all for reply my question.
The phone comes with the sim unlocked. You can use it with another carrier's sim card without any extra steps. (You may need to verify compatility of the radios/frequencies).
There is a second lock on the phone - the bootloader. You will see many threads regarding unlocking the bootloader, as well as "rooting" - getting superuser access. Unlocking the bootloader has nothing to do with the sim. Unlocking/locking the bootloader will not affect the sim card lock (or lack thereof).
It is, and always will be(unless Verizon tries to update it and lock it down), sim unlocked. So you can use any sim in it.
But it is not boot loader unlocked stock. You have to do that yourself.

thanks my fri.
I recently switched from AT&T to T-mobile. The phone however will not allow me to use t-mobile's sim card. The sim unlock code that ATT provided me does not work. I've called ATT and they can't figure it out.
Could the failure to unlock the sim have anything to do with these facts?
At one point I rooted the phone, but then an OTA update broke root
The Flixster app won't play anything because it sees an su binary which still exists but can't be used
Is there some sort of hack I can apply to SIM unlock my phone?
I've heard of considerable number of cases where the unlock code doesn't work because the phone was rooted, so that might very well be it.
I don't know what do you mean by "it broke root" because it seems at least some parts of are still present. If you have the "su" binary in the right directory and it has the right permissions, you can just install Superuser or SuperSU or any other superuser app from the market and you have a working root again. In which case you could also try unrooting (some SU apps support that) and try the unlock code again.

Thanks. Root checker says my phone is not rooted. Another checker app says everything is locked up, but the su binary does happen to still be around.
You are missing the point. Of course any tool out there will say it is not rooted. That is irrelevant.
I already suggested a course of action, you can either try it or not...

Yes, I am planning on trying it. I just haven't had time yet. I still wonder if there is a way to carrier-unlock the phone via hacking. I just don't know enough about it to even know what to google for. I will spend some more time searching the internet etc. I know rooting gives access to all files on the phone. I know rooting is different than bootloader unlocking, which allows you to put custom ROMs on. What I don't know, is if the carrier lock is something that is unlocked via bootloader unlock, or if it's something entirely different. Is carrier lock something that is actually outside the phone? Ie no matter how much phone hacking you do, you can't carrier unlock because the carrier lock is something that is actually on the network? Just trying to understand.
I see This a lot. It sounds like a crazy idea because we know entering in the wrong sim unlock code will lock up the phone. Recently I was unlocking a Nokia 920. Paid for the unlock got the code back tried entering it. Said it was wrong. Called blowfish unlocks(the company I use regularly) they told me to keep putting it in until it was supposed to lock up the phone. Believe me I didn't just jump up and do it. But in the end I said screw it. And kept entering it. In the end it unlocked. I'm not saying this is the case with your phone. Just that I've seen it happen.

eddified, I had the same issue as you when I bought my Atrix off of eBay.
Took a while, but one option was flashing the Bell Canada radio and then unlocking. That worked. None of the ATT radios worked, but Bell did. This is the bell radio:

If the unlock works, you can flash back to the ATT radio. You can find different versions all over these forums, but the bell one is a huge PITA to find, so enjoy the link and good luck!

Thanks. Quick question, do I need to unlock the bootloader to flash a radio? I'm thinking no, but not sure.

I honestly cannot recall. I want to say that I never did a thing to the phone until I had it unlocked, but I'm not sure. Best I can say is try it and you'll find out one way or another.
ah.. it's coming back to me now. I think I put a different radio on the phone awhile back. That's probably what's causing the unlock to not work.
hey tonglebeak, are you saying even though my phone is intended for the US, and the radio is for Bell Canada, I can use it to unlock even while in the US?

Yes. I won't recommend staying on that radio, but that is what I had to do to get my ATT unlock code to work.
Bell Radio didn't work. Tried all kinds of radios. Nothing works.
I just got a new Tmobile LG V20 H918TN and haven't unlocked the sim yet.
Can I proceed with unlocking the bootloader and rooting the phone before unlocking the sim or does that need to be done first?
SIM unlock has nothing to do with bootloader unlock or root. You can do that without SIM unlocking.

Thanks so much for getting back to me so quickly. I figured that was the case, but better to be safe than sorry. In the past, when I rooted my phones, they were always old enough that the sim was already unlocked. This phone is so new that I can't unlock the sim without paying for it. I only need to wait about a month to be able to do that, but I wanted to unlock the bootloader and root my phone right away. I appreciate all the effort and work that this website provides. Cheers!
I've been trying to go through this forum to see if you have already answered this question but could not find any reference to it.
I received a Verizon Samsung Galaxy Tab S6 as a gift and even though it is supposedly unlocked I have difficulty using my local sims in it. For starters every time I insert a non Verizon sim I get a notification reminding me that it isn't a Verizon sim that I cannot dismiss. Also, I would like to remove and not disable the preloaded apps that came with the device and completely remove/change the Verizon startup logo. I has some prior experience with rooting older android phones (up to Android 6) but am a little worried about making any modifications to this tablet. I know there are step by step instructions on installing TWRP on the SM-T860 and T865 but can anyone be so kind as to walk me through just rooting my SM-T867V and removing the bloatware/boot logo and fixing the non Verizon sim thing so that my device can use the LTE capabilities?
VZW is known for locking the bootloaders of their devices so in short no TWRP or root. As for removing some of the bloat it can be done through ADB commands without root.
Thanks.
Thanks for the reply. Any links to the guide regarding the adb removal? And if I were to get the bootloader unlocked, what would be my next steps?
Here's a tutorial.
https://www.xda-developers.com/uninstall-carrier-oem-bloatware-without-root-access/
As for the bootloader I meant locked as in cannot be unlocked. No TWRP, No Root, No Custom Binaries Period. The only models of the Tab S6 that allow bootloader unlocks to my knowledge are the T860 or T865
Thanks again
I guess I have to annoy Verizon and have them unlock the bootloader. I really want to get rid off the branding and the non verizon sim message.

They definitely won't be unlocking the bootloader. However the SIM lock should be handled if the prerequisites are met.
