G2X Unlocked(SIM) on AT&T 4G

I know that I am not the only one looking at this phone as a way to get a great Dual Core, 4G, vanilla Android phone (unmolested by AT&T) but able to be used on the AT&T network. I have had great luck and a lot of fun with the AT&T Nexus One and I think this phone will be just a successful with the help of XDA DEV's
I wanted to start a thread here in the G2X section for people to share with other users how to's and what works with regards to using this phone on the AT&T network.
It may be to soon to get all the answers, but maybe someone is working the same answers.
Questions:
How easy will it be to obtain the SIM Unlock code from T-Mobile or LG?
I am going to buy the phone at retail, just may have to use T-Mobile for 60-90 days to get the Unlock code.
Will AT&T allow us to upgrade to 4G data plan without buying their 4G phone?
I know from researching the Atrix 4G that the AT&T data plan needed to be upgraded to a 4G plan but you could keep unlimited data.

If I remember Tmobile's unlock policy correctly you wont have to wait. You can request the unlock code right away if you pay full retail price. Unless that's changed recently of course but I dont think it has. Good luck with it.

Kind of a repeat of what is in this thread started by me (which you tried to hijack)

Re-posting what I have found here:
I just got off of the phone with t-mobile customer care (1-877-453-1304). I called them because I wanted clarification on this before I purchased 2 full retail price phones.
The program is called the "Sim Subsidy Unlock Program." It is for anyone that purchases a phone for the full retail price from a corporate store or an authorized retailer and pays all of the price upfront.
You need to call customer care, explain that you purchased a phone for full price and request a "remedy request form number." They will then open this request and you then have 7 days to fax the following to the Sim Unlock Team at 1-813-353-6557 :

It takes 24 to 72 hours to process and they will email you instructions to unlock your phone.

As for at&t's 4g, there currently using hspa+ also, so if it supports their 3g, you'll have at&t "4g" as well

Sorry, I don't know why they did not move that thread over to this forum. It was clearly labeled as a g2x thread.
That is great info from T-Mobile about the "Sim Subsidy Unlock Program."

Just expect to have below 3G upload speeds with AT&T.
Edit: nevermind... software vs hardware limitations. Nonetheless, screw AT&T

That is this NORMAL procedure ...unless the phone is "exclusive" to T-Mobile. In such a case they will NOT unlock it even if you paid full retail price. This is what happened to me with their dell streak 7, I had to return it as they would not unlock it no matter what and I paid full retail for it so please triple check before you buy as I think the the G2X is exclusive to T-Mobile in the US.

why does it work on at&t bands.... ANY PHONE and i repeat ANY phone can be unlocked.... the phone is made for two networkds (im guessing because of the possible merger) so no its not stuck to just tmobile... now i understand your stating that tmobile might not give the codes because it is an "exclusive tmobile phone" however!!!!! give this forum a few weeks and you will have it unlocked!
im sure there is away just like any other phone! (if im wrong and this is the only phone in the world that cant be unlocked you can kick me in the ****)

It's not even officially out yet. Of course you cannot find unlock codes for it.

I'm sure it CAN be unlocked if you can get the unlock code. If the device is exclusive to T-Mobile, they wont give the unlock codes out so u are left only with back door options like T-Mobile employees .

It officially has been on sale since the 15th, so yes, it is out yet. Also, I have seen unlock codes for phones that are about to be released. Especially if there is a European counterpart.
P.S. I'm getting especially sick of these carriers with phones being locked to carriers, locked down, locked/encrypted bootloaders. SMH.

not to pick a fight but NO its not officially out yet... it went on pre-order the 15th... that is not an official release if its just on pre-order
call customer service they will tell you the same
now as the same methods that worked with the O2x may not work with the G2x...

SIM unlock codes are provided by the phone manufacturer. When you make a request for an unlock code, the wireless company forwards the request to the manufacturer. The manufacturer e-mail's you the unlock code. If you're using an unlock service off the web they're doing the same thing. Devs have nothing to do with unlocking a SIM.

MANY of my phones have been unlocked by the help of people finding a way!
thanks for your input but my vibrant was unlocked without dealing with tmobile/manufacturers

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.

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] HTC Titan and Samsung Focus S

I have done that MS Smoked challenge. Do i have to activate the phone then unlock to use on Tmobile? Or can i just unlock and start using?

inteller said:
unlock codes (at least for the Titan) are not available from ATT. But I dont think you'll get anything other than Edge on that with T-Mo. If you are out of contract I'd suggest porting your number to Straight Talk and get an ATT compatible SIM.

I do not plan on using it with AT&T. I plan to use it with Tmobile. and thanks for letting me know about the unlock code. Do third party sites have the codes?

You got 2 phones?
Nice phones btw..
Too bad with tmobile you'll only get 2g. I have a titan and i love it on ATT.
Which phone did you lose the challenge with btw?

yeah i did one and my friend did one i traded in an BB8900 and BB8300

How do I unlock?

I'm switching carriers. My ATT contract is done and I want to move to T-Mobile. I want to keep this phone so how do I unlock it for T-Mobile without paying unlock genie or any other sites that offer unlock codes.
I manage to to unlock my older devices like HTC Vivid, Inspire 4G and even the Galaxy S2 SGH-1777 for free,but can't seem to find any information about the skyrocket mostly all are not free.

You can't

ATT would not give me the sim codes,because they wanted me to stay with them,but I need a cheaper plan and ATT would not work with me so T-Mobile has given me the best deal yet. I added this to those many posts to see if anyone would know right away if there's a free way of doing it,but I guess not.

I had mines unlock for $9.99

I had contacted AT&T 3 times about unlocking my phone and they could not find the unlock code. There database showed it did not exist. I tried a unlock company for 20 bucks and they could not unlock it either. I was refunded. Something makes me think some of these phone are only for one carrier? Because the first time I contacted AT&T about my wife's s2 to unlock, I got the code.

At&t moving to TMobile

Good afternoon all. I am thinking of switching my phone from AT&T over to TMobile. When I do this, will I then be able to install custom roms on the phone? Thanks in advance for your help.

If it is the AT&T model, then no. Only the carrier will change but the bootloader will still be locked and be unable to be unlocked at the present time. Sorry!

Thanks so much for answering this. I was about to switch over. Now I know it wouldn't do me any good.

Only good that would come of it is Tmo would pay your AT&T phone off and you can get a tmo v10 and unlock it. Tmo has binge on for youtube I use a lot . But if traveling AT&T has far superior coverage period .

I think I'll hold off on switching for awhile. I ended up getting the Note 7 on Tmo for business, so I'll definitely take advantage of Binge On. Thanks for the info.

I actually switched from ATT to T-Mobile last year. My best friend is a VP at T-Mobile. I have to say the phone was bootloader un-locked 10 minutes after leaving the store. Literally just a debug option. I live in North Texas, and where T-Mobile works they can't be beat. I was getting crazy speeds, 50+mbps. But there were lots of spots where it did not work. To the point I couldn't place or receive a call. Places that ATT and Verizon work. I also told them at the time of switching to them I needed two Cell Spots. I knew their service would not work at my home or at our lake home. They agreed, and for the next 5-6 months I played this game where they would only allow one to be activated at a time. So after about six months of it I bought out my contracts and came back to ATT. Yes I have a T-Mobile V10 unlocked, rooted, custom rom working on ATT. I get decent speeds but not what I get on the ATT Variant of the phone. I wish t-mobile was more complete on their coverage, while they may have coverage in more cities I don't think it's as complete coverage as ATT or Verizon. I also did not find that their plan was all that much cheaper than the ATT plan. Sorry for the long rant, just my two cents.

Is it possible to flash H960 international version .kdz file on H900 at&t version? If anyone does it, what are the issues caused? I was planning to do the same but I am new to LG.
Let me know if its possible and what are it's implications.
