If you got your phone from a carrier i.e. with a contract it is most likely locked to that carrier.
SIM lock means that you can only use SIM cards from the carrier you are locked to. If you SIM unlock your phone you will be able to use sim cards from other carriers or pay as you go plans without receiving the invalid sim message.
CID Lock means that your phones software is locked to your carrier. This means that you can only flash updates from that carrier. No custom flashing, no cross carrier flashing. Before you flash anything from this forum you will most likely need to be CID unlocked. Read the stickies to find out how to do this. Make sure you follow all the steps. The process works.
If you have not personally CID unlocked your device you must assume you ARE CID LOCKED. Even if someone before you unlocked your device it will not hurt to do it again. If you have any problems flashing your device this is the first question back that you will get when you ask for help.
god dammit. there is a wiki and nooooooo one reads it.

Great advice and gently put....!
Asking questions is ok but do your research 1st! 90% of what you need to know has already been discussed, so the answers are here. If you don't find an answer, by all means ask...it is a forum.

thanks for your help Zzan now i have understood the CID unlocking stuff
Cell Unlocker says they have the unlock code for the Vivid with a 100% guarantee and they say it's permanent. Is this the same unlock code that we need?

That's likely a SIM unlock code, which will allow the phone to work with a carrier other than the one that sold it. There's also a bootloader unlock code that we're supposed to be able to get direct from HTC at htcdev.com that will allow us to flash custom software to the phone, but right now nobody seems to have succeeded in getting that.
As bjg222 said. That is sim unlock to use it on another GSM carrier.

You may be right. I will send them an E-Mail and ask them.

Yes it is a sim card unlock, finally got an answer from my E-Mail

Yeah, most reports so far say that the AT&T version gives an error when going through the process on htcdev.com. (Haven't tried it personally, my phone won't be here till tomorrow)

I did go through the HTCDev.com site and followed the directions to submit for a Bootloader Unlock Code. It does error out say CID Not Allowed. This doesnt surprise me give the phone launched on Sunday.
I'm actually looking for a SIM unlock so I can use the Raider with a non Bell SIM. Tried Cellunlocker.net and despite the site saying they have it (and paying for it) I was emailed a couple of days later with a refund saying they don't have it yet.
Anyone know of a site that has the unlock code?
Hey:
Trying to help a friend unlock the bootlaoder on his S5 g900a. Was reading a how-to thread on this site, but now, can't find it. I want everyone to understand something...this is an S5 g900a, meaning; sold by AT&T. This particular model is a different animal than other S5's. AT&T 'locked" (or had Samsung) the bootloader. You CANNOT root this phone!!! and, so far, cannot unlock the factory 'locked" bootloader. So, need to unlock this phones bootloader using D/l software and instructions. His phone is running Mm 6.0.1 w/ 8Gb SD card. Someone here know what I'm discussing and could help?
THANX:
RICK
There are multiple threads that answer this...the Bootloader can not be unlocked at this time.

Evening John:
Not meaning to contradict or argue, but could you explain how/why E-Bay sells that particular model (g900a--AT&T) 'unlocked"...which couldn't be accomplished without unlocking the bootloader?
Rick
It's probably SIM unlocked meaning you can use on any carrier that uses a SIM card. Trust me the bootloader is locked tighter than fort Knox. There are some working on trying to unlock it though.
Note: This Thread is @svetius Approved!
NOTE: Thread locked and link removed until OP returns
SamPWND Bootloader Unlock Service
It is now possible to unlock the bootloader of USA/CAN Samsung S21 Models!
Note2: This is an informational thread that links to a paid service. Paid service is not a service provided by XDA.
The service described in this thread is simply to provide a remote service that will unlock the bootloader on USA Samsung devices released from the S10 and newer devices. This includes S10, N10, S20, N20, S21, Flip/Fold models, Tab S7 etc. devices which typically will have the letter U, U1, W or in some carrier specific cases might have a different letter, for example, N976V is Verizon N10! 5G model which is also unlockable. This service is not for Exynos variants or China/HK variants that are already unlockable by default.
Due to the nature of this service, there is no exploit that exists. It is also device specific so it is impossible to release any sort of exploit or method that would work on every device due to it being device specific. I will explain more of the process below but please understand that individual files are needed for me to purchase to unlock your devices and of course that is why this service is not able to be provided for free. You all know from my past experiences and posts that if I could provide a free method I would have already done so.
Spoiler: Process
1. First you should be sure to read the FAQ's and all other information on the website and in this thread etc. then be 100% sure that unlocking is what you want to do. Read the notes/disclaimers, refund policy, etc. etc.
2. If you decide unlocking through this service is what you want to do, proceed to the website REMOVED and in the menu go to the "Purchase" tab.
3. Be sure to read each step clearly and enter in accurate information. Form is designed to help walk you though getting your OneUI version, bootloader version, the correct DID etc. etc. It also includes a brief description of the refund policy as well as a signature box to sign just iindicating that you have read everything and agree. This is also done so that if you are on a device or a specific update/bootloader version that cannot be unlocked then it will tell you so and will not allow you to make a payment or will show 0$. If you can unlock your device, it will show you the price and allow you to make a payment once you have completed the form.
4. It will take 1-2 business days (not counting weekends, holidays, as well as life events such as if I get sick or life happens or my source is not available at the time etc.) to have the payment hit my bank account at which time I will send to my source to obtain your unlock "token."
5. Once token is received, I will proceed to message you on Telegram or Discord (whichever you prefer, you have the option to leave your username for both when filling out the form) and will send Instrucitons in a txt file along with modded ODIN (in case you don't already have it) as well as your unlock token so that you can unlock your device at your earliest convenience!
Spoiler: Notes
I wanted to try and keep the XDA threads short and clean so any notes or FAQ's you have questions for I suggest you view the website including the FAQ's first as well as the support group on TG is a good place to talk to others who have already unlocked or planning to unlock using this service as well as you can ask in this thread as usual.
The "Purchase Form" on the website when filled out correctly based on your device will tell you if your device is unlockable or not so fill that out first and if unlockable it will tell you the price at the end of which you can either pay or not depending on what you decide!
Spoiler: Disclaimers
-IMPORTANT - Do NOT blindly update if you are unlocked already or if you plan to unlock your bootloader via this service. Sammy has incremented the bootloader and updated some devices to OneUI 3.1 which breaks the BL unlock. Devices still on the same rev (i.e. S20 at time of this writing) then you can just flash back an older OneUI firmware and device will be unlocked again. If you update to OneUI 3.1 on new bootloader version then you likely will lost the unlock and can't downgrade (i.e. S20FE on rev2/3, N20 and S21 Models on rev2). That said, there are some devs posting some "safe" update files to allow you to update to latest firmware without losing your unlock so before taking any updates always check in the support group first. You have been warned!
- This method will unlock the bootloader allowing you to use custom firmware, custom kernels and everything else that is allowed with an unlocked bootloader including Magisk root.
- Please read the policies on the website including refund policy. Proceeding with the unlock service assumes you have read everything including the policies and decided to continue with the service.
- This DOES NOT unlock your SIM or carrier/network. it is NOT a SIM unlock.
- This process modifies the steady partition. Therefore if you end up messing with this partition or get another remote service such as combo flash or sim unlock service etc. that messes with the steady partition then you might overwrite the unlock and essentially relock the bootloader. Chances are if you have no idea what a steady partition is then I would not worry about it at all.
- Knox will be tripped. This means apps that rely on Knox flag not being tripped will no longer work i.e. Secure Folder, Samsung Pay etc.
- Once the device is unlocked, if for whatever reason it is locked again then it cannot be unlocked anymore. So make sure that once you unlock the bootloader that this is the choice you want to make and you want it unlocked.
- This service is strictly to unlock the bootloader. It is not a root thread, ROM service etc. What you choose to do with your device after being unlocked is your choice. Once device is unlocked, this thread/service will have served it's purpose. Links to other threads sources will likely be provided in another post just so users who are unlocking will have an easy reference and to keep this thread clean.
Spoiler: Feedback/Complaints
If you have any complaints about the service or want to provide feedback then please do so via PM and/or the contact page on the website or via TG/Discord if we have already spoke there etc. Do not bother the forum moderators with complaints regarding the service itself because they are not affiliated with the service and I simply got permission to post about and talk about the service. I assume this isn't something usually granted but I'd like to believe due to me being a long time member, contributor, developer and moderator that an exception was made. Keep in mind, if this somehow get's out of hand or goes south I am sure I will end up having to delete this thread. Let's not let it get to that point!
Spoiler: Purpose
- This is not a get rich quick scheme or something to make money. Trust me, I wouldn't even bother with this if my purpose was to make money because it is not very lucrative to say the least. There is cost involved with purchasing the actual unlock, site costs, payment gateway fees to be able to accept payments, time and effort to process the unlocks etc. so take all of that into consideration when weighing the cost.
- It has been years since USA models had a device that could be unlocked. I have spent countless weeks researching security since the S8. I released root methods for S8 devices as well as the S9/N9 devices at a later time which took a long time to figure out and that was just a basic root method. I was skeptical at first about this unlock process but trusted my sources and when I first unlocked my device I did various testing and concluded it is legit! At this time no one else knew about it, couldn't talk about it, etc. By word of mouth (until now), many devs/users have unlocked their device using this service. TWRP threads have popped up, some custom ROM threads have started popping up etc. The hope of going public is we get a lot more users purchasing and unlocking their devices (when it otherwise is not possible) and drives the development for USA devices.
XDA is the ONLY place I have published this post and would like to keep it that way. You are NOT allowed to create your own posts in regards to this service and if I see any other posts around this service I will ask to have it removed. You can however link to this XDA post if anyone has questions as to how your device was unlocked.
Spoiler: Website
Note: If you frequented the website before, I have removed the "forum" function from the website since we can discuss everything here on XDA in this thread so there is no need for a forum to be attached to my website any longer. Registration on the website is not required for anything. You can view the shop and purchase the service or view the ROM's section to see some of my SamPWND ROM's and download them etc. if you like all without registering or anything.

I wasn't sure where to ask this question, if I need to go somewhere else, please let me know. I am considering getting my ATT Bootloader unlocked - but I have a question - once the bootloader is unlocked, what happens when therre are new firmwear releases? Are we able to update when new Firmware is released? Or will that return the locked bootloader? Just want to be sure I understand potential issues I might have...
Thanks

It all really depends. Nothing is forever. Only way a update will break things is if samsung updates their security but doesnt usually happen often.
Thaat said, theres ways to update safely so I wouldnt just blind flash updates until its confirmed one way or the other. Usually its important if they increment the BL because then u cant flash older firmwsre.
Welp, I have the desire to get this done sometime soon. I just keep having busy weekends! But I wasn't aware that I'd be able to flash BL update packages so long as they don't relock the BL. Any idea on where I could find out if the next software update contains a BL file that'd relock me? If so, then I'd be doing this ASAP lol.

Thanks for your repsponse to my previous question - Of course, there is no way to know if and when Samsung will update/increment the bootloader, but if I am not mistaken, it doesn't happen very often. That being said, it sounds like as long as I am careful about updating - waiting to make sure the Bootloader hasn't been updated that way which prevents going backward - I most likely won't lose "the unlocked" when I update new firmware.
One last question (probably a dumb one) so if everything checks out with the Bootloader when new firmware is released, I assume that we can just use Odin to flash the updated firmware - is that correct?
- By the way, thanks for your help with this.

Yeah, but each software update has a bootloader update included, hence why I was asking where I could find out whether or not flashing that file via Odin would end up relocking the bootloader... I suppose we'll have to just check around here on the XDA forums to find out whether or not the updates would be flashable whilst having your BL unlocked... =(... So we may have to wait a few months until we start seeing posts discussing exactly that...that is, of course, unless Samsung publicly announces whether or not the BL update will have security changes... But being that I haven't had a Samsung phone for the last decade, I'm not really sure if they'd ever announce that information... But hey, that's the one question that's holding most people back from getting a bootloader unlock ¯\_(ツ)_/¯

@elliwigy Food for thought: Add on service: TWRP Install?
I would feel a lot better about $150.00 if I at least got a free TWRP install. I mean I bought a $60.00 screen protector and got it installed for free. Unlock phone and get free TWRP install. Advertise it as a limited time deal.
Either way I think it would be a great add-on service even if a small fee applied.
How long does it usually take to get a response back? I got the first email like 4 days ago, this is normal?
Like I'm waiting for the unlock code or whatever it is I use to unlock the bootloader, it's been 5 days now?

To you and others who fill out the form:
If you fill it out and it doesnt give you the option to pay or says 0$ then that means your device is not currently unlockable. Hence why you woukdnt get any response from me since I respond to those that are unlockable and have submitted payment.
I dod add yesterday if you are not unlockable itll give you a message saying you cannot unlock at this time to further clarify it.
I will update OP tonight as much has changed since first launching/posting SamPWND services.

According to OnePlus I was supposed to get an email with this code when my phone was sim unlocked. They claim they have no idea what I'm talking about and they would never help somebody void their warranty and are forbidden to do so. How the hell do you get this code when they don't even know what it is? I can't get my unlock token without it and they've already tried blaming OnePlus which is not who is responsible for this code. I can't even find someone who knows what unlocking a bootloader means and they keep mixing it up with sim unlock and keep accusing me of trying to switch to another network despite me being with them for 11 years
let us know if you or anykne founded
Try saying root unlock instead. Btw you should be able to do this process online automatically. I could be wrong, but that's how it's always been done with every other device with tokens.

When I go to OnePlus's unlock page it asks for the serial, the IMEI, and the 64 digit code emailed to you by T-Mobile. I have found a possible solution with adb but I don't know if it still works, something like "adb get_oem_unlock_code" or fastboot but I don't have the exact command on me at the moment. They have their own process worked out with T-Mobile but nobody at T-Mobile was taught anything about this
