Using AT&T with the Nexus S GT-i9020T?
Has anyone successfully done this?
I bought this model of the Nexus S recently, and have been really enthusiastic about the build quality of the device. However, actually setting up phone service has presented a few challenges.
I have found nothing but conflicting information about this all over the internet. The official Nexus S manual spec sheet seems to imply that the phone can play either the tri-band or the quad-band game. Some folks report that the phone will work with AT&T but will only allow you to use EDGE and not 3G service. There are websites which say that the phone can be unlocked, however, many posters here on the xda-developers forum say that the phone is always unlocked anyway.
I bought both a T-mobile simcard and an AT&T simcard. The T-mobile one works just great. After inserting the AT&T card, the phone sees the local AT&T cell tower, but when trying to connect, it says "Your sim card does not allow a connection on this network."
I took the phone into an AT&T store this afternoon and the customer service rep replaced my sim card - but the phone acted just the same. He told me that the phone was probably carrier locked - and that I could look for a shop to help me unlock it.
So what can be done? Will T-mobile give me an unlock code? Do I need to buy an unlocking code from some vendor on the internet? I am familiar enough with Linux to edit files on the phone using a hex editor if there's a way to unlock it that way (I read about this method in a conversation on xda-developers.com pertaining to the Galaxy S I9000).
Not sure about unlocking, but I do know the 9020t will only do voice and Edge on At&t.

Hardware is not capable of ATT 3G but all nexus devices should already be sim unlocked. Idk why you're experiencing that issue.
I really doubt the att Rep has any knowledge on the tmo nexus s, but I'm really suspecting att's similar card as the culprit, despite the fact that u replaced it.
Sorry I couldn't be of much help.

So... An update on the progress of my quest:
I called T-mobile today (on the phone: "611") where a customer service person tried and failed to authorize the unlock code. She then gave me a service number at Samsung to call: (888) 987 4357. Samsung took the information from me about the cell's phone number and the carrier... and after a bit, bounced me back, saying that I needed to call T-mobile again to see whether I could get them to issue the 8 digit "network control code" which can be derived from the IMEI number.
This time, the T-mobile rep said that she would submit a formal request for me that might take between two days and two weeks to process. She warned me that because I had not had the T-mobile account for 60 days there might be a problem with the approval - but that they might be able to do it, if I offered proof of purchase for the phone (proving that I paid full price for it). She took my email address, my landline number and some other bits of information from me, and promised I'd hear back in a few days.
For those who are interested in all the gory details... here's an update on the hoops I've been trying to jump through:

Hello,
I'm looking to buy an Android phone off of someone in my local area and need some questions answered before I go any further. I don't know what phone I want yet, but I'm just worried as to if the phone is going to be stolen or not. Because I don't want it to be registered stolen and locked from the carrier few days later or something. Is there anyway I can prevent this from happening? I called Wind Mobile (That's what I'm planning to get either the phone fully unlocked or at least locked to Wind Mobile) and asked if they can see if the phone is stolen using the IMEI number, and they told me no. Which is odd because I did some research and some suggest to call the original carrier with the IMEI number to see if it's registered stolen. But since that's out of the picture. Is there any other way I can see if the phone is stolen? I'm thinking ask for a receipt of purchase of some kind, but do receipts show the serial number or something to show that it is that specific phone that was bought? Some people are also saying they have Unbranded phones which I know means that it is straight from a manufacturer to the public. So does that mean it is unlocked to all carriers? Is there still an original carrier? And can it still be registered as stolen to the company and remotely locked? I know even unlocked phones can still be registered stolen to the original carrier it was once locked to, but don't know about unbranded since there was no carrier in the beginning. (To my knowledge) Thanks for the help. Sorry for the long post, just need these questions off my back.
A proof if purchase would probably work, and also look at when the device was registered to make sure the receipt isn't forged

Hi,
In November 2010, I purchased a Samsung Omnia 7 from Computer Exchange (where they sell 2nd hand tech equipment) for the early adopter price (£425). It was locked to the "3" network but i eventually found a seller on ebay selling unlock codes from a user named nckzone and the unlock code worked nicely. However, on saturday I found that I was unable to make calls. I gave my carrier T-mobile a call from a seperate number and they told me that the phone has been blacklisted or in otherwords, it got reported as lost/stolen...
I was advised to ask the seller of the unlock code about the issue however he isnt responding.
I was wondering how to go about this situation...this phone cost me some serious cash and im not even due to get a new phone yet. What should I do?
I'm thinking about reporting this problem to the police since I have all my documents and proof but I hear its possible to change the IMEI number. Im really bugged at the moment.

The only thing you can do is go to the police..
check your phone's IMEI against what is written on the sticker / your box (to check IMEI type *#06#)
If it is different 100% that the 'unlocker' is at fault and he f-ed up your phone.
Otherwise somebody has created a false report with the police in which case the problem can be solved by going to the police and they can look up who filed the report and have it all undone (of course bring the box + purchase proof with you).
Also another good tip for many many people looking for (free) unlock codes. Don't post your IMEI everywhere!!!! Doing that will result in this exact situation and if you did this, all this is 100% your own fault.
take care
Hey everyone, I have seen someone Samsung Galaxy S3's on craigslist for like $300 and their IMEI is blocked. Meaning either stolen, blocked, or the owner didn't pay a bill.
I honestly can care less, I just want to know if T-Mobile blocks an IMEI if I can still use Simple Mobile on it, or I will have to unlock it to use a AT&T or other GSM carrier. My main concern is for Simple Mobile though since it is my current network.
Also, I have heard of changing the IMEI, can anyone provide information about that?
Thanks.

I would get the ESN and call to see if they would activate it. That's what we used to do when I sold cell phone years ago.
The imei is the gsm equivalent of esn. Anyway, call them before you buy, and simple mobile is a T-Mobile subsidiary so if it's blacklisted on tmo it won't work on simple because the towers refuse to work with you. I say just call tmo and they might help you, but don't tell them you want to use it on simple because they might not.

No, it won't work on Simple Mobile, because Simple Mobile runs on T-Mobile. You're not allowed to discuss buying phones not owned by the seller. You don't own the phone if you pay the $200 to buy it and then stop paying the bills.
I have purchased CDMA phones on Craigslist for years now. I bought one phone with a bad ESN and learned the most important lesson with regards to buying a cell phone second hand...activate the phone before handing over any cash. If that means taking it to one of these places or meeting the seller at a place that unlocks phones (unless you have a laptop and the means to unlock it yourself prior to purchasing). Also even with the phone not activate it should still call customer service. Verify that the IMEI is good. If a seller acts shady when you tell them you are going to do this...save your gas.
how??

You can block an IMEI like you can block an ESN now if the phone is lost, stolen, or has an unpaid balance.

I had a Galaxy S 3 stolen yesterday. There is no way for me to get it back, I can get over that. What I can't get over is someone having my 3 month old phone and being able to use it with no problems.
I contacted T Mobile on 3 separate occasions to see if they could block the IMEI number because I have the original packaging. I was told from 3 different account specialists that T Mobile CANNOT block the IMEI. Whoever stole my phone just has to pop in a new sim card and the stolen phone will work just fine, and there is nothing I can do about it.
If anyone knows how I can get my stolen phone blocked, I'd love to hear how.

Escalate it and tell them you need that phone marked lost or stolen. They do it for non-payment, they can do it for lost or stolen phones.

Thanks so much for the reply. On all three occasions I escalated the matter as high as I could. Have you had an IMEI blocked personally by calling T Mobile?

I'm on Straight Talk AT&T. I've never had experience doing that, but I know it's possible because people have been scammed and end up with lost/stolen/non-payment T-Mobile phones that won't register onto the network.
well..

Sorry your phone was stolen but doing that is not going to stop anything. If it was password protected then they won't has access to it.
until they bring it to someone like myself who can wipe it and reuse it. Its a GSM so all i have to do is wipe it n pop a new sim in it and wola.
That's just how it is

Yes I've read many stories about people buying a used phone from a person and the imei being blocked. I am just confirming/questioning that this isn't possible (whether it's a recent thing or ever) with T Mobile.
This seems like a good way for stolen phones to be blocked, but what about customers that report their phones stolen to t-mobile and then sell it on craigslist (I know a few people that do this)..the poor sucker that bought the phone will have it activated and by the time T-mobile blacklists the number they are left with a worthless phone.

People just neeed to do their research and take precautions. If you don't put in the extra time to figure out how to buy a used phone safely, you're going to be taking a chance - and you get what you get.

Blacklisted
I work for a cell phone buy-back firm. Every since November of last year we have been running into blacklisted imeis. We've got phones coming back because the person who sold us the phone quit paying on a subsidized phone. Considering our agents call people all over the country attempting to buy their used or inactive phones, most people see us as way out. This hasn't been an issue with cdma phones because we can check esn. Two days ago checkesnfree.com added imei blacklisted. But what I don't understand is our audit department can put a live sim card in a blacklisted phone and make a successful test call. But when a customer tries to put it on an account, it can't be done. Can someone explain to me why this is. I understand the calls and text are using a different section of the tower than the data network uses. But any more than that I'm at a loss. Thanks
IMEI blocking is only inner company at the moment. If att black lists an imei it will not work on any carrier that piggy backs att towers. Soon it will become cross company and global.
