How to SIM Unlock? - One (M7) Q&A, Help & Troubleshooting

Hey guys,
I have an AT&T M7 that is off contract and obtained an unlock code directly from AT&T.
Now, how do I go and SIM unlock my device?
Any help/suggestion is much appreciated.
Thanks

If you already have your unlock code thats a good thing. Now to use it, you must shut your phone down, insert a foreign sim card (from a different carrier than AT&T, borrow a friend's sim card if necessary), boot it up and you should get prompted to enter the sim unlock code. Once done your phone is sim-unlocked and will accept any carrier sim card. Your phone must be running the stock rom btw (or a stock-ish rom, will not work on Cyanogenmod for example but should work on ARHD).

You would need a foreign sim card (non Tmobile sim card) to unlock it.

Am I dumb? Re: Unlocking

Hi. The day I got the HTC One (from Bell) I went through the "unlock bootloader" and rooting process. Everything went fine and I've been using various ROMs and Kernels.
My question is: Is my phone "unlocked" as in able to be used with other carriers? I thought that's what unlocking the bootloader is.
I'm asking this because I got a SIM card for cheap roaming in the US, which I tried to test yesterday. When I booted the phone after putting in the Roam sim card, it prompted me to enter an 8 digit access (or pin) code. I had no idea what that was. And when I called support they said I would get that prompt if my phone wasn't unlocked.
So... is unlocking bootloader the same as unlocking from a specific carrier?
Yes, you can use all carrer if your phone isn't SIMLocked by the carrier.
So, seems that your sim is blocked, 8 digit for pin is the puk for unlock your sim.
How can I know 100% if my phone is unlocked? (other than inserting a SIM from another carriers). Is there something in settings that indicates unlocked?

I'm not sure what you mean. The phone was originally branded with Bell Canada. Then I unlocked the bootloader and rooted.

Unlocking the bootloader has nothing to do with unlocking the phone to use on other carriers. Your device is still SIM locked If you want to be able to use your phone with another carrier's SIM card, you will have to find a website that provides such service, like cellunlocker.netcellunlocker.net

AT&T HTC One on Vodaphone in NZ

I'm from the US and am in New Zealand for a month. I own an HTC One which I purchased from AT&T and have been using on their network in the States. I've unlocked the phone, and also have S-Off. I've purchased a prepaid SIM card from Vodaphone in New Zealand. When I insert the SIM card, the phone asks me for the 8 digit SIM unlock code, so I entered the 8 digit PUK code provided by Vodaphone with the SIM. The phone tells me this code is invalid. I'm not quite sure why this isn't working - is it possible I need to load a different firmware to use the phone in New Zealand?
Kernel is 3.4.10-g31f7883
Firmware looks like 3.62.401.1
I'm currently using ViperOne ROM.
Certainly appreciate any input on this issue.
Thanks,
Josh
Well, I did not realize that bootloader unlock and SIM unlock are two different things. That's a bit confusing. Wish I had figured that out prior to flying here.

If I remember correctly (this is all from memory), for the unlock code to work, you need
1) correct (original) CID and MID
2) stock ROM (some were able to do it on custom ROMs, but not sure if all work or only certain ones)
3) stock firmware for above ROM
4) stock recovery
5) LOCKED or RELOCKED bootloader
6) S-Off won't matter, and that will be your ticket to unlock again
you can search the forum here for SIM UNLOCK, there are quite a few similar cases, which got solved by a combination of points 1 through 5.
If anyone stumbles onto this thread in the future...
Turns out I needed a code from AT&T, as I needed to carrier unlock the phone before being able to use the Vodaphone SIM. I tried contacting AT&T to get the code, but they won't give it to you unless you are out of contract.
I was able to get an unlock code using option 5 in this thread:
http://forum.xda-developers.com/showthread.php?t=2242473
I loaded a stock ROM, but left the bootloader and my custom recovery on there, and the unlock code worked just fine.

help! my M8 didn't ask me about the unlock code

I try to unlock my Sprint M8,I tried T-mobile and AT&T sim card.
But my phone didn't likes youtube video, My phone didn't ask me about the unlock code. It just simply tell me the sim card is Invalid.
I have tried to use the unlock helper to unlock it, but it just unlock the internation lock.
I still want to unlock the domestic carrier lock.
Is it the ROM problem?
My phone use the Android 4.4.3,and it is S-OFF.
Please help me!
If you're trying to unlock your phone to use it on another domestic carrier, you're not going to be able to do that. SIM unlocking will work for international use.

Carrier Unlock without alternate SIM?

So I've gotten the unlock code from AT&T but the instructions tell me to insert a SIM card from another carrier in order to get the prompt to enter it. I don't have any other SIM cards at the moment to do this. Is there another way to get the prompt?
Thanks!
I'm also going to give Swappa a try for the first time for this sale rather than eBay. Figured people would be more hip to a carrier unlocked, s-off, GPE custom rom M7 there!
No

just go to another carrier and ask them you wanna test if your phone can connect to their network because you are considering switching to their network. They will try with one of their sim card, enter the code and voila.
