I'm really not sure this is the correct place to put this question (Mods, please move it if needed) .... as it sort of needs to be where both the UK SG-SIII users as well as T-Mobile SG-SIII users will both see it.
I contacted T-Mobile C'S and got them to email me an Unlock Code so that I could use my phone while in UK visiting my Mum for 2weeks, but when the email came the very first part of the instructions says "you must perform this unlock function with a NON T-Mobile SIM card installed"
Hmmm well since I am still in Florida, I can't do anything ahead of time but I wanted to try and research / find out what my options were when I get over there (flying into Manchester) ahead of time so that I know what I am going to do when I land.
Anyone out there with experience at international travel, multiple SIMs, pay-as-you-go plans etc?
Any help would be much appreciated. Thanks
It's easy to get it unlocked ... just use one of your friends ATT sim cards from their iPhone because s3 requires micro sim. Pop it in turn it on, it will ask for the code, put it in and your good to go. Then just put your sim card back in and your phone is unlocked for any gsm. When you get over seas find a service that has sim cards pop the sim in and your ready to go.

My Desire came from vodafone on contract, it was officially branded. It didn't come with vodafone software or anything but did originally need a gold card to root it.
I have rooted, installed custom recovery and ROM, gone S-OFF.
Is my phone sim locked to vodafone? I have put an old T-Mobile sim card in and it booted, no errors, in status it does show the phone number associated with the T-Mobile sim and am showing signal. If I try to make a call I get 'mobile network not available'. I'm sure there is no credit left on that sim, so that might explain that.
Anyway to know for sure, I am going to be in the states for almost two months and want to take it with me and get a payg sim card there.
Thanks!
Vodafone don't tend to SIM lock their phones anymore, try another SIM that you know is working (but if you have no credit you should still be able to receive calls)
Im pretty sure vodaphone network locks their devices, in order to unlock your device and be able to put other network sim cards in the phone and be able to use them you have to request a sim-unlock code from vodaphone or buy one online. Im currently in a similar position where I actually have a code but cant use it, most probable because I have a custom rom installed. When you enter your non-vodaphone sim does it not ask for a sim-unlock code?
Edit: I guess im wrong about vodaphone's policy then! Ignore all of the above!

Thanks,
Well, was not able to receive calls but then again that sim card has not been used in 2-3 years so it is possibly not 'network aware' anymore. I'll see if I can pick up a current sim card somewhere to test.
Either way I guess worst case scenario is paying to get it unlocked in the States, so no big deal.
Thanks for the help guys.
Do we have way to unlock the sim cards in our WinPhos yet? I've looked around quite a bit but all I'm finding is dev unlocks which I already have. I'm really trying to avoid calling my carrier for a subsidy code or trusting some website to provide it. Any help would be GREATLY appreciated!
Dial ##782# to Sim Unlock your Phone
Interesting. I am looking for a way to sim unlock my hd7. I didn't know about this code I typed it in and got a message saying it is already unlocked I am running deepshining V3. I tried it on my girlfriends stock hd7 mango and got the same message. I hope it is this simple. I will try a non o2 sim and see what happens. Cheers for the tip

Same here, said I'm already unlocked. I need to find a T-Mobile sim to give this a shot...I too hope it's really as simple as this...
This did not unlock my sim card slot btw. Put a t-mobile sim in my phone and it rejected it while asking for the subsidy code.
Any other ideas from the crowd?
Call your provider and tell them you are going to be traveling to Europe for the holidays and you want to get a local sim card while you are there. They will send you an unlock code for free. Easy enough.
Hello I have My usa Cell phone and it is rooted And I Put My Uk carrier sim card in and it keeps asking for a unlock code anyway around this?
you need the unlock code. you have 2 options
1. buy the code from online there is bunch of sites that offer them please be carfull research before you buy .
2. contact tmobile they will give you the code free if you were a customer for more than 2 month i think "recommended"
Good Luck
can you please report back what radio you're using in the UK and what your download speeds are. Do you also get HSPA+?
Unlocking sim card For UK On Usa Phone
Unlocking your phone is just the reversal of the process of locking. It all concerns with a code, which is put into the phone through certain software. In the same way, software is needed to reverse the logic. This process is available for almost every type of mobile phones today. You have several options for unlocking a phone but the best and simplest way is to use such a service provider expertise, which can do the job for you. If you want best international sim card, I'm recommending you to use holidayphone prepaid sim cards. Because it is very cheap and best in all aspect of services.

hey... you're like... 4 months late
I've had my S3 about 5 months, I bought it retail from ebay from a seller that didn't unlock it, it is still tied to AT&T. I use Straight Talk as my service as at&t or T-moblie will work with out unlocking them. I want to unlock my phone now and have a question.
Beings that the micro sim in my phone is straight talk and is working, how do I unlock my phone? from what I've read about unlocking, you need to have a NON-WORKING sim to be able to unlock it. Or is there a way to unlock it with out a sim in it?
thanks for your time.
You actually need a Sim that is not att, to unlock. You will need the unlock code from att or you can buy them on the internet. I was able to get my unlock code for my S2 from att. You have to have the phone on their service for at least 6 months, you call them say you are going out of the county for a few weeks, and bam!, they give you the unlock code.
Once you have the code, you need to put in an activated sim from another provider other than att, when you turn the phone on you'll be asked to enter unlock code. Enter the code, hit enter, bam unlocked.
This won't work with a sim that is not active.
So if you have a straight talk sim in, and have for six months, and its working, and its a i747, then I think you have a unlocked phone.

just to clarify, you do NOT have to have AT&T for any given amount of time before you receive an unlock code.
i was an AT&T customer for all of 10 days and got my unlock code for my Galaxy S3. it is VERY dependent on the agent you speak to for asking for an unlock code.
anyways, since you are using Straight Talk, you should have an unlocked phone. best way to test is try to put a different SIM card in it and see what happens.
I was told my device was "ineligible" to be unlocked. AT&T sucks.
If you don't want to waste time talking to a rep that may or may not help you, use this method, it's easy and free: http://forum.xda-developers.com/showthread.php?t=2014982 (it's for the Note II but it works on the AT&T S3). You don't need a non-working sim for this method to work, but you won't know if it worked until you put in a non-working sim.
Also, you'll likely only get Edge network on T-Mobile unless you happen to be one of the lucky few in an areas where you can get 3G or H+.
But as posted in other threads, if you're going to call AT&T, call their International Support line: 1-800-335-4685 (found here: http://forum.xda-developers.com/showthread.php?t=1962453&page=16 )

Thanks for all the great info, I'll give these a try.
so, i recently bought this phone new in box. opened the box, inserted my sim and it does not recognize it. now i should mention that i use walmart family mobile as my carrier. could that be my problem? i'm told that t-mobile phones work since there a branch of t-mobile but so far no luck. im going from a captivate to this phone, so the sim was bigger. i used the template deal and cut it down to the micro sim size which i thought could be my problem but the sim happily works in the captivate. any help with this would be greatly appreciated. i will answer all questions to my greatest abilities and i apologize in advance if im the 18th person to ask this today like other questions

You can not swap SIM cards from one provider to another unless your phone is unlocked..
You need to purchase a T-Mobile SIM card kit...

but this works with other t-mobile phones and i know this because i have done it without an unlock, but those were older older phones like the s1 and s2. does the t999l specifically pick a fight? maybe a quirk of 4.1.2?

I believe in order for this to work on this device, you would need to unlock it..
I'm no expert, but this is my personal experience..
In order for me to test this, I would have to have both devices and YOUR sim card..

well a man can hope right? and from my extensive research i have found that because of the fancy L the only way to unlock this is via a dude on ebay, or a code directly from t-mobile. i doubt t-mobile would do this for a non-contract phone though. it certainly does suck to suck.
Esn?

"Doesn't recognize it" please explain what exactly what is happening. If it is still asking for a SIM to be inserted, you will need a new SIM, but if it is asking for a Unlock PIN Code or similar, then you will need to unlock the phone to use with a non-TMo provider. Personally, I think that since you cut the SIM and it is not lining up. You should get a new (factory made, not cut) Micro-SIM. Also, I believe that it should work with Simple, Straight Talk and Walmart Family on any TMo phone.
