Currently no, if you have been in good standing with TMOUS they will issue the unlock most of the time.

Unlocked
Try to call them and see if they can provide you with Unlock code.
I called T-mobile on 2nd day after i got my Sensation to request unlock code. they open a case and gave me a case #, very next day after i called i received email from T-Mobile with code and instructions for unlocking. I pop my friends ATT sim and enter the code. now i have Sim Unlocked Sensation.
Rep @ TMO told me that they need to contact HTC and once HTC will give them a code they will email it to me. but they provide me the code in about 24 Hrs. that is super fast . Thank you TMO
By the way i am with TMO form last 4 yrs, so they gave me a code to unlocked the Sensation. oh I also got sensation for free for renewing the contract. thanks TMO

So you signed a new contract to get the phone and then immediately broke it and switched to at&t, with edge internet? That would be really nice of T mobile if they really did that but I don't imagine them giving the code, if there is one, that easily.especially being that most people who have the sensation just signed a two year contract.

Who said he switched to AT&t? He probably just wanted an unlocked Sensation

NO man, I just RENEW my Contract for 2 more year, that's how i was able to get Phone for free. I really wanted Unlocked phone (for travelling to my home country), so I requested UNLOCK code
Email i got form TMO. Also check out the PIC I took
T-Mobile Sim Unlock Request
Sim Unlock Reference: 4XXXXXX
IMEI: 3550XXXXXXXXXXX
Unlock Code: 051XXXXX
Thank you for taking the time to contact T-Mobile. Below you will see the Instructions for unlocking your HTC device.
1. Insert the foreign SIM card
2. Power on the device and the display should read "Please input unlock code"
3. Enter the unlock code and the device should display "Phone is unlocked."
4. Allow the phone to scan the network (or manually click on the antenna icon to do this)
It is very important that the instructions and SIM unlock code are entered correctly as listed. If you receive an error message while performing the instructions do not make any further attempts to unlock the handset. Please be aware that if an excessive amount of incorrect attempts are made, the phone will be permanently locked. You will need to verify the IMEI by pressing *#06# and contact Customer Care for support.
Thank You,
Sim Unlock Department
T-Mobile USA, Inc.

I'm thinking about picking up a Sensation 4G too - but I will be traveling to Europe frequently. I will have it unlocked and will use EU SIM cards. Now the question is, does the 4G support EU 3G bands?
When you pop in an AT&T SIM card - can you get 3G on the AT&T network? Or just EDGE?
Thanks!

1. Yes, the Sensation supports UMTS 2100, which is used in most countries for 3G. You won't be able to get 3G in countries that use 850, but there are only a few of those. You can check specific countries here:
http://www.gsmarena.com/network-bands.php3?sCountry=GERMANY
or here:
http://www.worldtimezone.com/gsm.html
2. As mentioned above unlocking a US Sensation 4G does not enable 850 3G, which is required for full coverage on ATT's network. So, you can only get EDGE. Pretty sure the European and Canadian versions of the Sensation do support 850 3G.

can this phone be unlocked?

Im thinking of buying an at&t version of this phone to use with rogers here in canada and i wanted to know whether it can be unlocked to be used with any gsm carrier?

yes you can but from what I hear, you cannot use the unlock tool from the market so you'll have to get the unlock code from AT&T or online after a small fee.

hmmm why?
from what i have been reading the Rogers one (which is the SGS2 LTE) is the international version and probably get the ICS upgrade before the AT&T Skyrocket.
Skyrocket is something AT&T made.
Also Carrier IQ is installed in the AT&T ones out of the box...
i could be all wrong since i am new to the android scene, but this is what i gathered from reading around..
The Rogers one is nice IMHO

The reason i was asking was because i found some at&t versions on ebay which were selling for less than the rogers version on craigslist.

ahhhh makes sense ; >

When I called AT&T the told me they can't give me the unlock code for my Skyrocket "you will have to pay a third party" (sic) !!!
I would love to get some feedback if you are able to get the unlock code from AT&T

I have the Rogers Galaxy S2 LTE and purchased an unlock code from cellularunlock for 9 dollars and it worked perfectly. Also rooted my phone with the Super One Click app. Worked like a charm. Zeide

I have AT&T in the US and I called them to unlock the Skyrocket. At first the lady said it wasn't possible. Then I explained that I travel overseas frequently and there are some countries that don't have any AT&T signal or service. She said OK and then did some more digging: you have to have purchased the phone at full price, not be an abuser of data roaming, and submit the original receipt. Once they send you this form to fill out it takes a few days to receive the code. I avoided all that mumbo jumbo by complaining and finally the lady said she would send my case to the "technicians". Three days later I got an email with the unlock code and instructions. It depends on who you get on the phone. Don't give up. Or just pay the $20-$30 for the unlock code online.
Sent from my Galaxy Nexus using XDA App

I unlocked mine using cellunlocker.net It was $28 and they sent me the unlock code in a few hours.
I unlocked it using my wife's T mobile SIM. After unlocking, it took several minutes for the T Mobile network to come on but it works fine. I made several calls with my wife's SIM in my phone. It does get EDGE data speeds which you would expect.

[Q] Anybody have luck with sim unlock on AT&T?

I tried to get my SGS II Skyrocket from AT&T unlocked for use with local sim cards when I travel internationally later this month. But AT&T reps say they could not find an unlock code for it! Tried with Samsung too... but they want me to call AT&T
Did anybody have any luck getting the phone unlocked from AT&T?

I was told the phone was exclusive to at&t so they would not provide an unlock code. Keep calling back.

Please show me a link.

I called and asked for my unlock code. A nice rep took a while to find the info to tell me. He said with less than one year left on my contract, I could get an unlock code. I have more than a year left. Also I have heard they are legaly required to give you an unlock code when your contract does expire.

SIM Unlock Code
If you had the phone for over 6 months, you can request for the SIM unlock code. The reps will tell you they don't have the code, and give you the run around that it's not available. Not true. Ask to speak to a supervisor, and ask him/her to put in a case (ticket number) to request for a SIM Unlock code based on your IMEI number. Once they do that, you'll have to wait about 4 days for the code to arrive. I got mine on June 27, 4 days after I requested it. I had my phone since Oct/Nov 2011. Good luck!

I had no issues changing my unlock code with http://www.unlockclient.com/. I'm now able to use a t-mobile and O2 sim with out issue.

unlock I727
you can get an unlock code or unlock it via cable via SRS software.
We have been doing this since 2006.
link is: http://www.unlocksamsungonline.com/unlocksamsung/I727
Note that if you have flashed custom roms this might cause problems for unlocking so first unlock then flash a custom rom. If you want to unlock after flashing a custom rom, flash back to original first!
Providers are often behind with their databases with unlock codes and also they are never able to provide unfreeze codes as they simply do not have them.

AT&T Skyrocket SIM Unlock
I filed a complaint with the Better Business Bureau and the Federal Communications Commission. I also e-mailed the president of AT&T. Today is the third day after the BBB complaint. Someone from the office of the president called me today in regards to my BBB complaint. She gave me the SIM unlock code for my Skyrocket. The presidents e-mail addresses are [email protected] and [email protected]. Good Luck!

Check this out bro. Works and I tested it. It works

I don't know if you use custom ROMs or not but you need custom recovery.

unlock for t-mobile?

is it possible to get the at&t mini and unlock it for t-mobile? wasn't sure if it takes awhile for the mini to be unlockable and are the carriers compatible with one another? from what I understand both work off of gsm but will I have issues with t-mobiles 4g/etc...

I just got my at&t one mini unlocked today and can receive/send voice and text without issue using a T-Mobile USA sim card. However, I don't yet have any data connection. I was told it could take up to 24 hours so I'll report back tomorrow.

Hooray for me! Just called T-Mobile tech support and they walked me through manually configuring the APN and now I've got voice, text, and freakin' LTE! I was told this phone wouldn't work with our LTE, but it looks like they were WRONG! HTC One mini on T-Mobile USA FTW!

I can get edge, umts, hspa+, and LTE! But I'm also in Kansas City where we have a refarmed network. #winning

I tried to, but AT&T couldn't get it to unlock the first time, so they had to open a case file and some tech guy called me back the next day and got it done. Took all of 30 seconds.

yes

My apologies if this question is foolish, but AT&T says they can't unlock my htc one mini for me, even though I paid for it in full, says there is no unlock code for it. Talk to tech support and everything, and they still deny there is a code available.
So I try ebay and other pay for code websites; probably like 8 of them can't find an unlock code. They have even searched the 'not found' databases.
Is it possible to have a phone that is 'unlockable?" or one that has no code for it? Are there any alternative methods to unlock the sim to use on other networks? I've never had such a hard time finding an unlock code for a cell phone.
Thanks in advance for any help you guys can provide!

As mentioned earlier, this same thing happened to me. The customer service reps don't know why, but their computers tell them they don't have an unlock code. They have to open a "case" for you and some technical guru will call you back with the unlock code.
Keep in mind (I found this out the hard way), unless you root the phone, you won't be able to use the WiFi hotspot feature on T-mobile.

Well...I've done this, opened a case number, and the response was I was not eligable. Said I have to have active service for 6 months before I can have an unlock code. I manage to buy this outright on a gophone account.
Is it possible to software unlock via cable or some alternate method? It doesn't look like AT&T is willing to help me out. I'm not looking to use on T-mobile, I want to use this out of country.

i bought a code for $25 from cellunlocker.net, turn around was 2 days but it worked fine...

Well I finally managed get an unlock code through AT&T.
Spent and hour last week with tech support, and then a supervisor had to then request the unlock code specially on my behalf to another person higher up. Got a case number and 1 week later this morning got the code. It was a painful process, totally not worth the time. Better to pay for the code.
I had tried cellunlocker.net 2 weeks ago, but I guess the code wasn't available then but is now.
Note to self; don't buy a phone when its totally brand new to unlock, wait a few weeks or months.

Awesome! I am going to try the same!

[Q] Need a quick answer please regarding T-Mob service.

Can someone please tell me if it is possible to use a prepaid Sim with a TMob Edge? If so would it have to be a Tmob brand Sim card? If this is not possible stock would it be possible through root access and possibly a rom change? I'd ultimately like to be able to use an AT&T prepaid sim. Thank you in advance for any info. I'm in a time crunch for this info so i really appreciate it.
P.S.- is this phone carrier unlocked out of the box?

The phone is not carrier unlocked out of the box. You will have to sim unlock through T-Mobile or another source if T-Mobile will not unlock it for you. It should work with an AT&T prepaid sim after you sim unlock.

Tmo will unlock it only if there is no balance on your phone. They will ask you why you want to unlock then give you the pin to unlock.

Do i need t mobile to unlock it even if it is rooted, what If i were to just flash say a stock at&t rom to the phone, could i then use am att prepay sim?
Thanks for the answrs!

Yes you need T-Mobile to unlock it. If not it doesnt matter if you have it rooted or not. You wont be able to use other sim cards or carrier's if you dont have it unlocked by T-Mobile.

So i just called and requested an international and carrier unlock. I was told that there was two ways to unlock it, first way being just a carrier unlock and second way being both international and carrier unlock which is what i requested. Then they asked for my imei and my email address and said that i would recieve the code and instructions via email within 24 hours. Is this the same process that you went through bryanthomas007? After completing this process is it possible to use a prepaid service?
