[Q] AT&T Captivate for use in EUROPE?

Hi folks
I´m new in android and want to ask if it´s possible to use a AT&T Captivate in Europe (e.g. Germany) after unlock with e.g. vodafone?
Read some threads with rooting and flash I9000 ROMs but not shure if there is way to use this phone in our local (german) network with non att sim card without any problems
Is there a CAPTIVATE ROM available with correct settings to use OUTSIDE the US?
Sorry for my noobness....

As of right now AT&T will not hand out unlock codes to sim-unlock the handset, so you'd be unable to use it with a non-AT&T sim.

sure? saw some offered on ebay UNLOCKED so i guess there is a way outside att...
@all: any proved links to unlook or user that have experience with it?

There is a thread in captivate general about sim unlocking. The ebay sellers were not able to unlock the phones and only a few lucky ones have been able to get unlock codes out of at&t by complaining. There is some sort of turbo sim device a couple of them are using though.

Could you give me more details about that "turbo sim device" theme?

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,

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.

AT&T version carrier sim unlock?

Anyone try a carrier sim unlock on the ATT One XL? I ordered from Amazon, so I don't have mine yet. With bootloader unlock restriction, I'm worried about carrier unlock. I was hoping to use the phone on my trip to New Zealand next month.
Any ideas if there will be an issue with services like cellunlocker, etc?
Thanks!

enter in your IMEI in their site and find out

I'm wondering the same thing. Someone posted in another thread that cellunlocker's codes on his AT&T One X didn't work and he wound up having to get a refund. Is this something that will be solved in a matter of time? Or is there a chance that the AT&T One X will never be carrier unlocked?

I'm getting at&t hox aswell...
i will be getting at&t hox and i have to unlock it to work on Orange here...is that possible ?
these "code" site, are they guaranteed ?

That was me. I have had one unlock fail and get a refund.
I have two more unlocks pending (at the same time). I will update everyone as soon as I get this baby unlocked with success.

Cheapest place to unlock HTC One X (Rogers)

I tried searching for reputable sites to do this but cannot find any. Should any eBay listing do? ($2-3).
Is there a way to unlock and check if the phone is unlocked without having another SIM? I want to do this for proactive purposes before my trip and do not have access to another carrier's microSIM.

You need another carrier's sim unfortunately. At least that's what others have said.
Sent from my HTC One XL

I guess I will have to take my chances with the unlock code and keep it in hand until I get another SIM card, was thinking it was as simple as unlocking a BlackBerry.

Network unlocking

My Sprint variant arrives tomorrow and I'll need to network unlock it to use with my carrier (wanted the unlocked bootloader).
Am I going to have to go on say eBay and do the IMEI method or will the first sim inserted feature work?
If the IMEI way, are there 3rd parties currently that support the S7?
note: I don't know how generating the code works so I don't know if it's model dependent when generating it.
EDIT: Can confirm first sim inserted does not work. Prompted with "Invalid SIM card" with an AT&T sim in Sprint variant.

I can tell you, as far as I know no one has tried the 1st Sim inserted locks to that network theory...I hope you give it a shot, as it could confirm or deny this theory.
Sprint has unlocked bootloaders?
Good questions btw, I'd like answers to these questions as well

I was surprised too. I asked a rep before purchasing and they said they did; as well as a couple others stating it. But rather that's true or not, I'll find out soon enough

I can confirm that the AT&T s7 was sim unlocked. Bought outright at Bestbuy and picked up tonight, I put my cricket sim in and it worked perfectly. I can not verify if it is locked to cricket or not since I don't have another carrier sim to try. I received no notifications that I had a cricket sim or anything it just worked.

Cricket works on all? AT&T phones because Cricket uses the AT&T network. I have an AT&T S5 using cricket with no changes needed but APN settings. I'll confirm tomorrow, unless someone else does before hand, if the first sim feature works with a Sprint variant.

Unless I'm mistaken even on AT&T phones you still had to unlock then to us a cricket Sim

I didn't with my S5, unless something changed.

The OEM unlock option is in the developer options of the att s7. I only have an att sim though, so i can't test it. I didn't buy mine outright.

Same for T-Mobile. There is also a "Device Unlock" app in the T-Mobile folder/

I will try a different sim today...
My phone arrives later this week - no next day shipping for me I guess I will try my Vodafone SIM first when it arrives and see what happens.
Will post the results if no one beats me to it.

FYI... The OEM unlock option in developer options has absolutely nothing to do with Sim unlock.

it begins the process of allowing you to unlock your bootloader, if your bootloader is unlockable.

Ah ha

The reason its because of this phonearena dot com/news/Certain-versions-of-the-Galaxy-S7Galaxy-S7-edge-lock-to-the-carrier-of-the-first-SIM-inserted_id78809

Since you bought the phone outright, can you still get on the GearVR promotion bandwagon?
I am on the ATT Prepaid (GoPhone) plan and don't want to change over to post-paid. But I was told I can't actually pre-order and still retain my plans with GoPhone.

Hey TehPirate_,
Unfortunately the Sprint S7 and S7 edge can't be unlocked by code
you can however contact sprint to request the to unlock it
The other GSM networks can all be unlocked by code such as AT&T, MetroPCS, T-Mobile(by Unlock app confirmed unlocked today Rogers, Fido, Telus, Bell, Vodafone, etc

Took me half a day of phone calls and emails but managed to get sprint to unlock it for me.
