Changing carrier and phone not working with new SIM - AT&T Samsung Galaxy S II SGH-I777

I have been using ATT service on this i777, now going to China and will be using their carrier for a long time. I learnt I have to go to either China Mobile or China Unicom if I'm to stick with this device. However both carrier's SIMs resulted in "SIM card not provisioned" notice and it's not working.
I am wondering if calling ATT helps, or I need a SIM unlock code, or I have to install a custom ROM to somehow bypass the SIM check? Or even more? I love this phone so I don't want to buy a new one here in China.
Any help is greatly appreciated!!

Your phone needs to be sim unlocked. If it is not unlocked already, then by far the easiest route is to call AT&T to get the unlock code.

oh I'm sorry, I think I already unlocked it (spent a few bucks and got the code on a website)
I put in China Mobile's SIM and entered the code in the prompt box. Do I still need an unlock code from ATT ?

Thanks for the reply. I replied you above but didn't quote.

If the phone is already sim unlocked, then you don't need to unlock it again.
I've never gone through the unlock process, or traveled over seas, so I'm not the best person to answer your questions. I think "not provisioned' indicates that the sim is not activated, or that the phone is not set up for the network, or something like that. You may need to input the correct apn for the network. Maybe you could go to the carrier's store and find someone who could help you?
Maybe someone with experience will jump in and help.

[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....

[Q] unlockable from network?

Hi all
I am thinking of getting rid of my Galaxy SIi to get one of these. One of the ones I have seen to buy is locked to T mobile so I was wondering if it is possible to unlock these phones as I am on vodagone. If so is it a fairly easy procedure?
Thanks
Impossible at the moment. XPS is a mighty fine device so try swapping w/ some1 or something similar
Impossible? I'm chatting with my phone operator (Telenor) about operatorunlock-code. And as far as I know, the operator-code will make the phone accessible for other operators.
But the issue I got right now is there is no place to enter this long operator-code
I mean: impossible to unlock by yourself if operator doesn't allow unlocking or bills it insanely, and you don't have the money/don't want to pay such amount.

Put in a different operator's sim card and restart the phone.
It'll automatically ask you for the code

Got prompted to enter an Unlock code.

My problem is that when I use a SIM from another carrier and boot my phone up, I do NOT get this: “SIM network unlock PIN” message. My phone only says "SIM card is locked" and want me to type in PIN.

Seems your SIM card is locked. I remember old phones gave you an option to add a pin code onto the sim card itself. There was a warning that if you forget it you're screwed. Try getting a new SIM from the carrier

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.

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.

Global GSM not working

Hey i came to hong kong for a business trip and tried a local GSM sim but i get this sim is not supported error. DOes anyone know how to fix this.
I tried same thing sim on another phone it works. So not sure what the issue is ? did i need to get an unlock code from verizon before i left ?
If you can get access to a computer for awhile go through Adams unlock process in the original android dev forum and you'll be carrier unlocked, not sure what Verizon would give you for a code cant hurt to call and ask, but keep in mind unlocking it is something that can be done by you from here

You sure it wasn't a "Non-Verizon SIM" on going notification? I've read of people using all sorts of different carrier SIMs and they all had at least voice/sms service if they had a signal. The phone is already SIM unlocked, so VZW couldnt give you much.
Sent from my Galaxy Note II
The non-Verizon SIM notification doesn't actually do anything. You should be able to get voice just by putting the SIM in. To set up data, you'll need to be rooted and add the APN manually.

You can't make it "SIM-free", it's gonna need a SIM if you want to use the device on a mobile network.
Unlocking allows using the device on other networks with other SIMs, it does not allow a device to work on a network without a SIM.

I think You didn`t understand me. I don`t want to use phone without SIM. I just want to unlock phone from one mobal carrier, so I could use another.
We say in Serbia that the phone is SIM free if it is not locked on a network. Specifically in my case, this phone is locked for MTS mobile, but I want to use VIP mobile.
I tried SGS2 sim unlock by Chainfire and did not work.

Unlock methods vary from one device to another, it can even be different on the same device with a different firmware build number/android version.
If it were me, I would just do a Google search for:
"How to SIM unlock (your model number)"
You might have to use your stock firmware build number to get more specific information. If that doesn't find anything, there probably isn't a known unlock method for your device, if there were, someone would have posted it somewhere. Other than that, you can try asking your mobile carrier to provide you with the unlock information/service.
