Developer Converted doesn't prompt for Sim Unlock code?? - AT&T HTC One (M8)

I got the AT&T M8 and I've been Developer Edition converted for a long time now. So the other day I requested the unlock code for my M8 from AT&T and they emailed it to me but when I power off the phone put in Tmobile Sim and turn back on it never prompts for the Carrier unlock code. It boots up and it prompts the menu up for me to select what carrier I want.
So did the Developer conversion some how unlocked my M8??
Or do I just need to RUU back to stock and apply the unlock code??
Thanks

Hmm, interesting. If the T-Mob SIM works for voice/data service, than it would appear that the conversion did in fact unlock the SIM.
Just hold onto the code, just in case.

[Q] Is it possible to remove network lock without an unlock code?

I have reviewed similar threads for a few days but have not found any answers. The simple question I have is in the title:
Can you unlock the ATT Atrix without an unlock code.
However the situation is a bit more complicated and ill explain.
I have been traveling the past few months and was in Costa Rica for a month. I decided to purchase a local SIM so I could use my phone without paying ridiculous ATT roaming charges. I inserted the SIM and it was locked, unaware of the network lock I inserted my personal code thinking that may be it. No luck and returned to my old ATT SIM. At this point it still worked but a few days passed and I tried again, still no avail so I contacted ATT. It just so happened the 6 month mark was coming up from the original purchase date of my phone so they would provide the unlock code in 4 days time. I waited and finally received, after inserting the code it did not work and I contacted ATT back to assure they provided the proper code as they had to send me a replacement phone a few months prior due to my original Atrix crapping out. They checked it out and determined it was correct but it never worked. I finally inserted my original ATT SIM back into the phone and it also requested network unlock code. Now I am back in the states and even with the original ATT SIM it still requests for the network unlock code. I tried unlocking and flashing with CM7 beta and STILL requests unlock code. So basically the phone is useless for network data but will work fine as a mini tablet i suppose connected to WIFI.
So with that explanation does anyone have any idea on bypassing this or removing this entirely, not even to use overseas but just on the ATT network!
Additionally
ATT provided me with another Atrix to alleviate my troubles so im not entirely phoneless. However I would like to sell one of these and possibly purchase the GS2 0_o
I have contacted 3 cell phone unlocking sites explaining the situation and only one has responded but not with any answers.
HELP!
if you got a new phone, is it still asking for a network unlock code?
No. Its working fine, but I still have this perfectly good working phone I would rather use and sell the brand new one. Unless I cant get rid of this unlock problem I suppose Ill sell it as is. Any takers?
Hi, I talk to att once when i want to unlock my atrix and they told me if the phone is more than six months old the give you the unlock code for free.
so for the atrix if that is your phone you can ask att for your code since august 21.
just call att customer support.
hope this help.
try a diff sim card with data plan and see if it still asks for code
or try flashing a custom rom
I suppose I was not clear in the OP. ATT DID provide this code for me. I did flash a custom rom already.
As far as using a different SIM card I tried to use a second SIM that ATT provided and still nothing.
I am assuming this is a very unique situation and probably wont find any answers unless someone has successfully unlocked the phone by flashing some special ROM.
Flashing a ROM of any kind will never sim-unlock your phone.... ever. period.
The only way to resolve this is through AT&T. The only way to sim-unlock is with the code it requests.... must have proper code. That is the only way. So, I would talk to AT&T about it, in person, at a local store.
I unlocked the inspire 4G simple by rooting and flashing a custom rom didnt ask for network password after that it worked on tmobile
With edge service no. 3g or 4g different bands between tmobile and att

Just the info I was looking for. Basically the phone is boned in that case. Spent a good with with ATT advanced tech support and motorola to no avail.
What I do want to know is WHERE this information is stored out of curiosity. It seems the modding community would have tinkered with some hacks to remove the sim lock at some point.

Tried to screen shot it but it wont allow in the screen. The request comes as soon as I turn the phone on. If I dismiss it I can use the phone I just wont have cellular access.
Ok so I am reposting and not editing as I feel this deserves a bump.
I got my new Atrix unlock code from ATT today and tried it on the new Atrix I received and that one ALSO will not unlock.
Is there ANY ATT Atrix sim unlocked and if so how did you go about doing it? I have only found one thread and no response via PM.
How to SIM unlock Atrix!
I have read both your post and I believe you used a ATT sim card that was not in use or a GO phone Sim card. Am I correct so far? To sim unlock you have to insert a non ATT sim card!! No go phone sim card or a non active att sim!
Call one of your friends and borrow a Verizon sim or Tmobile sim. You only have 5 tries to do this. So as for your first Atrix I believe it is already locked permanently to ATT. Dont ruin your second Atrix.

Well I found that if you push #073887* in the dialer it will actually prompt you for the unlock code. I tried this with NO sim in at first and that is when it said it was unsuccessful. However late last night I inserted my ATT SIM back in and tried again just for ****s. Entered in #073887* and typed the unlock code and viola, it worked. Interesting information for anyone who wants to unlock there Atrix WITHOUT another carriers SIM!
But back to my original issue. I wouldn't mind if the original atrix was locked to ATT, at least I would still be able to use it. The problem is that it wont work with ANY SIM. My thoughts is that it is a glitch and locked the phone to... nothing?
To make matters worse I emailed cellunlocker.net explained the issue and they said they thought if they requested a carrier unlock code it would work. Paid the 20 and 10 minutes later they sent me the same unlock code ATT had provided. Now the hassle of obtaining a refund.
are you selling the phone?

Yea. Both.
you have to use a *different* sim card than your regular carrier uses (ex - I'm on AT&T, so i used a Boost Mobile Sim to unlock my Atrix) You cannot use YOUR sim to sim-unlock.

Yes you can, by the method I explained in my previous post. It works!
There may be some confusion. The one im referring to (the original ATRIX) will not unlock with an ATT sim, a TMOB sim, a verizon SIM, or even a Costa Rican SIM. NO matter WHAT the SIM is in the "original" phone it always prompts me for a SIM unlock password. Like I said I believe it to be a glitch, intending to lock it to the ATT SIM but in reality it locked it to NO SIM.
So to restate.
YES you can unlock an ATT Atrix with only an ATT SIM in the phone using the method I explained. ( I did it with the phone in my hand right now)
and
NO my original Atrix will not unlock regardless of SIM installed or method.
i will send you a p.m with my offer
Just out of curiousity did you ever set up the sim card lock feature in the location and security settings. It will ask you for the unlock code every time you turn your phone on...shot in the dark here....

Where to get free unlock codes or to go bring it into a location to get unlocked

Does anyone know where I can get free unlock codes for my AT&T Jetstream tablet?
Does anyone know of a location to bring my AT&T Jetstream tablet into in the NYC & NNJ areato get it unlocked. Please help.
what do you want to unlock? SIM, bootloader, ???
If you plan to travel and need to change the SIM, call AT&T customer service they will give you the SIM unlock code.
If you want to unlock the bootloader and change the Kernel and/or ROM go to htcdev.com and unlock.
I did it in eBay for $3 (SIM-unlock)

I need to borrow a Sim card from someone so I can unlock the Sim. I was told that will prompt me to enter a code to unlock it. Will ANY Sim work? Even if it is a Nextel Sim card?

Any sim will work-inserting it will prompt you for a code. But to get the code, you need to get the unlock code from either AT&T or use online sim unlock sites.
Regarding the borrow part, you can just use your regular mobile's sim to unlock it. However I think there was a thread that had something about some changes with the data and stuff with AT&T happening on removing the sim. Read it up and make sure to get AT&T's help once you change your sim back to their's after whatever use you intend to do.

What do you mean aboutbchanges with the data? If I will be using another carrier then what do I care about AT& T's data changes?

I thought you might be going back to AT&T. Hence. Any case if you plan on shifting permanently, just go ahead.

What I would be hoping for now that I have gotten my HTC Jetstream Tablet SIM Unlocked, is that CLEAR comes out with SIM Cards. CLEAR has Modems, Hotspots, and USB Hotspots. They should come out with SIM Cards now since there are a LOT more devices that can use them for just the reason of why people get the Mobile Hotspots.

AT&T One was sim unlocked, but it's relocked itself?

I got an HTC One from AT&T back in June and immediately unlocked it. It worked fine with T-Mobile prepaid for a month, but the coverage sucked. I went back to AT&T prepaid.
I got a new Nexus 5 and am selling the One.
When the guy came to buy it, he popped in his T-Mobile SIM and the phone asked for a PIN on boot. What gives? Did the phone re-lock itself? AT&T customer service seemed pretty clueless on this...

It appears that his T-Mobile SIM card has the pin lock enabled, has nothing to do with your phone. It requires the SIM pin code to be enabled any time it's inserted into a phone.
Once your phone is carrier unlocked it will never re-lock itself.

I don't think that's true. I had a SGS2 i777 (AT&T) that I got AT&T to give me the unlock code. My son was using it on T-Mo prepaid. Once he put the sim in an old phone and try to set a passwd, but ended up locking the sim card. Put the sim back in the SGS2 and had the same problem. Called T-Mobile to get the PUC code. Typed the PUC code in, and the SGS2 gave a message about sim locked. Called AT&T again, and had to get the sim unlock code again.
My wife's iphone 4 had been unlocked previously, and a few month later had to call at&t again to unlock it. Don't know what caused the re-lock (she never used non-AT&T sim after the 1st unlock), but it can happen.

I'm confused...

So, I have an AT&T M8 that I unlocked the bootloader, and S-Off using sunshine, and SuperCID. I wanted to convert to a Google Play Edition, which I did successfully. I then wanted to SIM unlock my phone. So I bought an unlock code which I have in my possession.
I decided I wanted Sense back, so I reversed as much as I could, and flashed the ViperOne ROM. I did not have an alternate SIM card (T-Mobile) until today. I put it in, and boom, I'm on the network? No unlock code request or anything... I tried putting my CID back to the AT&T one but it still works just fine with the T-Mobile SIM...
I may end up selling this phone at some point, but want to be absolutely sure it is permanently SIM unlocked...To my knowledge, I haven't done anything to the phone that would indicate this... How can I be sure?
I may be wrong but I believe that achieving s-off will sim unlock your phone.

At least in the case of Sunshine, it does not SIM unlock. I checked with jcase in their IRC support channel...
AFAIK, S-off methods do not intentionally SIM unlock. Its always been a separate process. For instance, for firewater, s-off was also a separate process: http://forum.xda-developers.com/showthread.php?t=2708572
If OP wants to be "sure" its SIM unlocked, you can try the process above. Although, I don't know of a way to confirm, other than inserting another carrier's SIM (which you have already done).
The GPE edition is SIM unlocked. Is it possible that something in the conversion also unlocks the SIM?

Unlocked SM-N900P, SIM Unlock each restart

Sprint internationally unlocked my phone for my move to Germany. I signed up with T-mobile (Germany) and the phone works flawlessly as it pertains to voice and data. The only issue is that every time I restart the phone, or in the event the battery dies, I have to manually enter the Sim Unlock code each time, prior to using the phone. The 2 x Iphones my other family members use, have an option which saves the sim unlock code and thus, there is no requirement for them to manually input the SIm code each time their phones restart.
Is there a way to do this with the SM-N900P?
