I understand there are two ways to unlock your HTC aria.
One is to buy the unlock codes on some website.
The second, free way is to call AT&T after three months and they will unlock it for free.
However, I have called AT&T twice and they don't have the unlock code available even after giving them my IMEI number. I'm puzzled by this. Is anyone else having the same problem? They said the computer or database don't have the Aria unlock code in the system. What's going on here?
Big brother just tricked you. They are tracking you now. Throw the phone away. Use cash only. Don't use your real name.

AT&T doesn't have to give you the unlock code for the Aria until the exclusivity for that device has expired. Your only choice for now is to unlock it using a third party website.
Get the unlock code through a website like the most of us did, its just $15 or $20 bucks and they send you an email with the code almost instantly..

be sure to search ebay first. i found an unlock code for my backflip for only 2 dollars, the same for a few other phones I've had!
!
You know...I'd be interested to find out how these unlock codes are generated...seems like people are robbing people of their money when they are selling these things...it probably isn't the easiest thing in the world to figure the algorithm out (if that's how they do it) but i can only imagine that once you do figure it out, it's a short process thereafter to generate unlock codes for people based on whatever information they need...

there is software that does this. unfortunately i think they require a USB Dongle to run the s/w and it is expensive.... until the Russians crack it anyway. LOL
anyone suggest a reliable unlocking site?? there are so many scams out there taking money and not producing a usable code.
Most of the unlock website I found are reliable as far as give me money back when they can't get it. ATT and quite a few inexpensive website can't unlock my Aria. Some on top of refund, give me free unlock code for future. I end up found someone said "doing it manually". Took him 3 day and $25 later, he gave me the code.

rooting just gives you the "ultimate-true-genuine" etc rights to modify the phone the way you want it
to unlock the phone it's a different story. You will only need to unlock it if you're traveling outside the US
Or to switch to T-mobile.

Last sentence not quite correct; a clarification. You don't need to unlock if you travel outside the US. The Aria works just fine in other countries; you will incur additional costs as a result because you are roaming on foreign networks but AT&T has plans you can buy ahead of time and terminate when you get back home. Now the clarification part: if you do have an unlocked phone you can use a SIM card from other providers in other countries (which you will have to purchase or borrow from someone that lives there). Unlocking simply allows you to use another SIM cards, fore example, like Tmobile (a GSM network) in the US. If you don't unlock, your are limited to AT&T SIM cards. Unlocking is really not necessary unless you want to run on different networks in the US and outside the US.
Don't worry i will help you...You can get the Unlock code better from Online site,Basically network provider ask you to wait to get the code from them,they will give the code,it's available in Data base,So if you need Code immediately means you can get the unlock code from here www.Superunlockcodes.com and get the free unlocking instructions from here Mobileunlockguide.com and unlock it step by step.

I travel quite a lot through Europe and since AT&T's roaming charges are quite high, I had to unlock my Aria so that I can use local GSM carriers over there. I used www.cellunlocker.net last year. Their "regular" service for $4.99 was not able to produce the code for my Aria and they gave me a refund. I then purchased their "advanced" service for $19.99 and had the unlock code in 3 hours.
One more note about the benefit of unlocking: Once your phone is unlocked, it stays unlocked. So you need to purchase and use the unlock code only once.

Hey Guys,
I live in Ontario, Canada and ended up buying an AT&T Atrix 4G online that was supposed to be unlocked however is not...(I'm with Rogers)
I know the typical unlock method buy purchasing an unlock code from some sites or a local cell phone unlock shop, however I have been hearing about how one can call the service provider and given the right reasons - receive an unlock code from them.
My problem is if I were to try this out, would I call my service provider? Rogers
OR
Would I call the original manufacturer of this phone? AT&T
I do understand that part of the process of getting the unlock code involves the IMEI # of the phone.
Thanks,
If it's an AT&T phone, they will have unlock codes. Worst that can happen is they say no. If they do, pay to get the codes from one of the reputable sites.
mobileincanada is a pretty good site, you might find something cheaper. who knows. sucks that you were lied to overall.
I need to try and find a number I can call from Canada which will allow me to talk to someone from AT&T who realizes my situation...I can't seem to get through.
What sites do you use to sim unlock HTC Amaze?
I checked a couple and found out they scams - they only take money and do not send out unlock codes. It would be great if those who unlocked would mention sites they used and the unlock cost so that the rest of us could find the best unlock price and would not get into scam unlock sites
just call tmobile, takes 24 for them to email u the code.

You can say you're not a T-mobile customer but would like to use their T-mobile phone. Most reps don't really care much, they might try to sell you a contract or whatever, but in the end, they'll just give in and give you the code. Well that's how it was about a year ago. idk if it changed now.
Oh and from what I remembered it is actually much easier to get the code when you're not a customer, because if you were, they'll be asking you why do you want it unlocked and stuff (are you changing carriers) etc etc.
yeah call tmo, I was in mexico unlocking phones, just ask for the IEMI number, and within 2/3 days you get an email with the code, no charge...
This is the first GSM phone I have had and would like to know the benefits to unlocking the SIM card. What can I do with an unlocked SIM? I know if it's unlocked I could use any GSM carrier but what else if any thing?

It only lets you use it with other GSM carriers/providers. That's all. Nothing else.
I called T-Mobile twice and they basically said that since I do not have an account with T-Mobile they can't give me an unlock code. They said I need to call HTC directly. When I called HTC they said that I need to call T-Mobile to get the unlock code.
That's why I would like some reports on what online unlocking services anyone used to unlock the Amaze so that people like me wouldn't get scammed by some website that only take the money and do not provide an unlock code. Also the unlock price would give an idea of what site is the cheapest of the reliable ones.

Usually the prices in Canada are higher than in the states buying a phone off craigslist. I bought it in Seattle for $380. Also I'm not on Telus in Canada and Telus is a CDMA provider. If they offer GSM service it would be the same as of AT&T band. I'm on Wind which operates on the same band as T-Mobile so to make sure my phone works on my carrier I bought a phone from T-Mobile.
I started this thread just to find out what online unlocking sevices are reliable and cost less so that I and other people who buy phones off eBay or craigslist could find an easy way to unlock their phones.
Try http://www.cellunlocker.net/
you can also use:
http://www.htcimeiunlock.com/htc-imei-unlock.php
I've used it to get an unlock code for an Inspire (which I used on the Roger's network) only took 5 min's to receive the code. I'm currently waiting on a response regarding a Telus Amaze unlock code, guess it's no so fast on release day.

I found user reviews where they paid to cellunlocker.net and never got a code nor money back.
I'm going to try http://www.htcimeiunlock.com/htc-imei-unlock.php It costs $25
EDIT: I got the phone unlocked. It took only 5 minutes and $25 to get the code
So, I have some relatives who lives in the US who can buy me a cyan 920 in December which is unavailable outside the US. The US pricing is also impressive since the no-contract version costs just $449 unlike the actual version that will come here (Indonesia) at about $649 and by about January or something. I also found this website which can unlock the 920 for $49.99. Should I take the plunge?
http://www.cellunlock.net/Unlock_AT_T_Nokia_Lumia_920_p/unlockattn920.htm
I would do more research on the internet to see if the website is actually legit. The places I get my unlock codes are from eBay from Top Sellers.
For the AT&T Lumia 900, they have unlock codes on eBay, but you have to complete the two year contract.
There might be a way to unlock the phone.
If your relatives can call AT&T confirming you can get the phone unlocked if they buy it outright (full retail price)
I think you should be able to get it unlocked if you pay full price.
Also I found this site who afirm they will unlock it too.
http://www.gsmunlockusa.com/u-s-a-at-t-nokia-lumia-610-710-800-820-900-920(1-3-days)-p-908.html
Hope someone can try and confirm if this one is a trusted site.
Unfortunately, AT&T is not being very helpful regarding unlocking the 920. Even when paid full-price. I don't intend on actually buying the phone with contract, but I just want to know if you guys have similar success/fail stories since this will be the first time for me to unlock phones. (also the reliability of the websites would be awesome)
PS. I also wonder where these websites get the unlock codes from, and what would happen if those codes would not work.
when the first generation of Windows Phones arrives, i bought a Samsung Focus V1.3 (which is my actual phone) and i get the unlock code from FastGSM. I ask them for the unlock code for Lumia 920 and i get this response:
Hello,
sorry but the unlocking service is not available yet for this phone model.
Kind regards,

the word "yet" makes me think that unlock codes arent far away.
Cellunlock,net is reputable website - I have gotten unlock codes for many a phone through them. Only once, they were not able to get an unlock code for me, but they refunded my money promptly.
For the AT&T 920, they do claim a turnaround time of 5-10 days. I'm not sure why it is so long, but do you want to wait that long to find out?
BTW, if you do decide to go with Cellunlock.net, use the code "CRACKB50" for 50% off on the unlock price.
Hope some AT&T Lumia owner try to unlock it. If they unlock it, i can buy my own lumia and use it in my country with no risk. BTW, using the voucher code from rajeshr the unlock code cost 19.99.
Edit: I found other service for unlock rogers devices
http://unlock.canadagsm.ca/nokia/Nokia-Lumia-920-LTE-network-unlock/
don't know if canadagsm is a trusted site, but again, some one can try it.

Reputable site, but they don't have any unlock codes as yet. I got an email from them this morning stating that and asking me to wait for another 2-3 days. I guess we'll wait and see.

ive had two lumia 920's and ATT actually sent me the unlock code for the first one! However, I think the CSR made a mistake when submitting my request, because when I received the unlock code it says its for a Lumia 900.
Did it work? I'm not sure because I have already exchanged the phone for another color!
I submitted another request for the second phone, but promptly received a notice saying they wont unlock because of the exclusivity period.
@rohitgarewal: How did you ask for the unlock code and for what reasons?
@BigwaveMx: Were you able to use tethering with other carriers after the unlock?
Thanks, btw for the replies!
i haven't (yet) a lumia 920. Still waitting to buy the unlock code for use it in my country. However, I read in some places that there is a problem with tethering in AT&T and Rogers devices. For me, is not a big deal have tethering. I bealive the international version works fine.

Got 20 digit code from ATT
I called and requested an unlock code to use the phone while traveling abroad (Bought the phone at full price). I did get an 20 digit unlock code but it didn't work. Called them back and they said they will send a new request. I'll let you know how it goes.

I don't think the developer unlock is the same as network unlock. From what I read on that link, developer unlock allows you to sideload (using an Android term; i.e. not from the market) apps for development and testing. It does not say anything about unlocking the phone for other carriers.

Any news about the unlocking for AT&T devices? Still looking for a cheap unlocked Lumia but can't find anything cheapper than $777 US
Expansys USA is apparently selling the AT&T branded 920 unlocked for $620. Can't post links yet, not enough posts. It is recently went from "We have no confirmed lead time for this item" to "Stock Usually Ships In 10 Days." This looks like a very attractive choice, if you don't mind the att logo I'm considering buying one of these.
Ok, i will check it. Thanks for the heads!
I found a new service to unlock AT&T lock. Sadly I haven't any IMEI code to test. Maybe someone can try it. Btw, I doesn't know if is a trusted site.
http://www.unlockitnow.com/Nokia/Lumia_920_unlock_code.php
I've been emailing every site I find that says they can unlock the phones..
So far they have all replied negatively.
I just emailed your site and I'm waiting on a reply now.
I also called AT&T and gave them a sad story.. hoping that they would sympathize with me and give me the code.
That didn't work either
After I get a response from these guys.. I'll post up a list of all the sites I've tried.
Been following this story for a while about how it seems like no online unlock service has been able to unlock the att lumia 920. I have also seen that multiple people it seems were given codes from at&t that would not work. Well last week I submitted an unlock request for my lumia 920 through at&t over the phone and today I received an email that had the 20 digit code. So I put an old T-Mobile sim in the phone, turned it on, entered the code, and it said pin accepted! This confirms that at&t is at least able to issue correct unlock codes but it doesn't explain why some work and some don't. (As far as I can find I'm the first one to actually get a working code)
For everyone who is still waiting for an unlock it is worth a shot to give them a call. If they say they won't unlock it due to the exclusivity deal, ask for a supervisor who can put the unlock request through.

I'd assume you won't have much luck if you aren't a current att customer. The supervisor who put in the unlock request told me that they can submit an unlock request for any phone except the iPhone which has to be out of contract to be unlocked. My lumia is under contract but I've also been with att for at least 7 years.
1 hour of battling. 1 agent escalated to sup, no result. Another agent and another escalation, no results for me.

Same fore me - no real battling though and "only" 30 mins on the phone for nothing. Agent also spoke with supervisor. June was what they told me (so much for "it's the same for all Lumia 920s, not just your device..."). And, of course, they even don't have the codes yet.
Idk why they won't budge for you guys, the only thing I can say is keep trying until you get an agent who will submit the unlock request for it.

Will do. I tried to gently push him to still submit a request, even though it fails, so that I had something in return (if it is just the negative reply from the unlock team) to follow up with. However, he would not submit the request because it would be the same result as he is telling me - no code available for my IMEI yet.
I'm currently very busy at work so I can't spend 30-60mins each day chatting with AT&T. Will try in a week or two.
BTW, I guess you being a long-time AT&T customer could have also been influential. I am a 2-day customer because I cancelled service again due to bad voice quality at my work location. However, paying the ETF, I fulfilled my contractual obligations so I'm only asking AT&T to fulfill theirs (3.1 of the Wireless Customer Agreement)...

Yeah my lumia is under contract but yes I have also been a customer for at least 7 years. The problem is there is no standardization with these unlock requests so it seems like it's just the luck of the draw of who you talk to... I'd be really surprised if you got a denial email, it seems like the difficult part is just getting the agent to submit the unlock request...

It's the standard exclusive device wait for 6 months after release rule on AT&T for contract phones. Dunno about other carriers.
So whenever you bought it, plus 6 months, you can sim unlock it.

Apparently there is no way at all to unlock currently except thru ATT. I guess that is harder than I expected b/c it seems no one in this thread has been able to get an unlock code. It just depends on the CSR you get on the phone, I got them to unlock it on my first call to them so I guess I just got very lucky.
guys, I'm from Ukraine
please tell me. Can I write to at & t email?
What information do I need to write that would have been any result ..?
and in advance sorry for my spelling mistakes))
I called them back in Dec 2012 and got the unlock code from at&t; however the code only 11 digit and will not work.
Does anyone know or could confirm how digit the code should be?
Also, does it have to be a T-Mobile chip or any GSM chip will work?

Unfortunately, there seem to be very few people who managed to get an unlock code from AT&T, and most of them were long-term AT&T customers. If you are not a customer, neither phone nor e-mail support is likely to get you anything meaningful. We'll just have to wait and hope that codes will leak out to 3rd parties earlier than next May.

for those who tried the 20 digit code for the lumia 920. try this. i had that problem with my lumia 900 from at&t i got the code and entered it and it would not accept the code. i had to use all ten tries and then it asked me to enter MY PUK code. i then entered the exact same unlock code as the PUK code and it unlocked the nokia lumia 900. my theory was that i never activated the phone with an at&t sim card i just bough it and popped in my foreign sim. i tried it with multiple unactivated nokia lumia 900s from at&t and it work. so if you bought a lumia 920 but didn't activate it with an at&t sim card this may be the reason the unlock code didn't work, you can either activate the phone with an at&t sim or try this process that i've used.
