I believe most models (US) shipped with NFC, but most carriers (in the US at least) disabled it.

I believe T-Mobile was the only US carrier not to disable NFC. Although it should be enabled AFAIK with ICS updates for other carriers if the hardware is present.

Ok wait wait, let me clarify.
i9100 = NO
i9100P = YES (it's an i9100 exactly, but with NFC. ROMs for i9100 will work, but need to be modified to show NFC settings, otherwise no NFC options will show)
i9100G = NO, it's completely different from the i9100 hardware (TI-OMAP instead of Exynos). ROMs from i9100/P don't work.
T989 (T-Mobile GS2) = YES, but it's completely different from the i9100 hardware (Snapdragon S3 instead of Exynos). ROMs from i9100/P don't work.
i777 (AT&T GS2) = YES* , stock ROMs disable it. ROMs from i9100 work because they're the same phone (it's really an i9100P because it has NFC) but you need to modify button layout or the buttons won't work in the ROM.
D710 (Sprint GS2) = NO

thank u guys, i'll buy european i9100...

afaik, european S II GT-I9100P comes with NFC ... so if you want a european NFC version, you could try to find a GT-I9100P (e.g orange in France and TIM in Italy ).
...not sure which roms will work ....perhaps the same as on the GT-I9100T ...

Hmm, I think there is a nfc version for Europe -> the P version AND an Australian version with nfc- > the T version.... :what:
And Btw. AFAIK they changed the naming of the i9100G to i9100 in April/mai... Because nobody wanted a I9100G.... What a mess!

Which is messed up because it's a totally different phone and technically misleading...

So my question to you is if stock roms disable NFC on the i777 then why did my box say that it is NFC equipped and I was able to use it stock?

On my Australian T model it is not supported(doesnt work) but my P model is and (i9100)my standard one has no nfc

ICS upgrade might have re added it. Google "AT&T Galaxy S 2 NFC disabled".

my sgh-i777 has no indication of NFC on the box and was unusable stock. It does say "Near Field Communication" on the battery but I was only allowed to read some tags with a custom rom a while back. I'm on AOKP now and haven't tried anything with NFC as I gave up on it a while ago.
Is NFC fully functional on your i777?

The i777 is really an i9100P (European I9100 with NFC). So yes it should fully work on a ROM that supports it.

so thats mean can;t work for my gt1900..oppzzz

My sgh-i777 obviously came with it but turned off from carrier att. But I've been using nfc since gingerbread a dev entropy got it working back on 2.3.4 release from att. However the problem we do have is the lack of secure element which is why we can't use Google wallet for instance. Theirs been alot of debate over the secure element factor but besides that its fully functional.

There's no debate; it needs to be there or Wallet won't work. End of discussion. Any other NFC stuff should work.

Great info.
My brother just got the Nexus 7 and I was able to Beam a site I was browsing on chrome to him (I'm running AOKP btw). So it does work
But he tried to beam me a picture and it said the other device doesn't support receiving large files via beam ?
So now I know that my nfc works, what cool things can I do?

Pretty much anything else that newer NFC phones can do, except Google Wallet because that requires a separate chip called a Secure Element. NFC itself is a very slow, weak protocol. You can beam text easily, which is probably what happens when you beam something like a URL. But beaming a picture would take a looooot of time and power. So I think what happens is the NFC chip initiates a Wifi-Direct (Wifi-to-Wifi) or Bluetooth transfer.
Try buying Samsung Tectiles and using the app to trigger actions with NFC.

Is this phone an SGS II?

I just got this phone 2 days ago, it's t-mo branded, says Samsung galaxy S II Android 4g when it boots. Yet looking at some of the pics in this thread, my phone doesn't look like the ones depicted.
How do I tell which phone I have exactly?
Thanks.

This forum is for the international version which is different from the carrier versions, you can check in settings>about phone and it should tell you your exact model number, you can then google it to get more info about your specific device
Like the original Galaxy S, there's over 9000 different variations based on each carrier. This is the forum for the international S2

Well, instead of asking strangers, since it's a T-Mobile phone you could have gone here:
http://galaxy-s.t-mobile.com/samsun...zygt*VAygtzlw*VyBpAgf+mA55Byf*VyBpAgf+mA55Byf
Or, you could have put "Galaxy S II" in the nifty "find your device" box in the upper right hand corner of the forum. You'd have found this:

Thank you all. I'm not new around here, but again thank you for the information.

Your Tapatalk says you have the T-Mobile T989, which is a Galaxy S2 in name only. (It's a Samsung, it has a sAMOLED+ screen, but nothing else in that phone has anything in common with any other S2.)
There's a T989-specific forum if you go to the main XDA forum page and search the page for T989.
I got my phone through T-Mobile. Came via UPS.

T989 is T-Mobile version of the Gs2 family. your screen should be 4.5' instead of 4.3' and more rounded shape

And the T989 is the one variant I know of that doesn't have an Exynos - it has a Snapdragon CPU instead.

[TMOUS] Since S3 has wifi calling - can it be ripped and put into Galaxy Nexus?

Hi all,
Since the Galaxy S3 has now been released on TMOUS, can the setup/framework/etc be ported onto the GSM Galaxy Nexus?
Is that a reasonable expectation?
There is a lot of FUD going around about how the wifi calling is device-specific and cannot be ported to any device.
I can understand that to a certain extent but the S3 and Galaxy Nexus have a lot of similar innards from what I understand so I wanted to revisit the situation.
Short answer: no because of the ril.

Don't see it happening. The SGSIII and GNex actually don't have a lot in common in terms of insides.

This actually isn't relevant anymore. Since T-Mobile switched to IMS it no longer requires custom IRL/Kernel to authenticate over GAN.
IMS has already been open sourced: see imsdroid or andoird-ims
This should/could be supported in any current version of Android if someone took the time to figure this out and hand the know-how to do so.
Unfortunately, I am not that person, but I think this could be realized considering the information available.
I have confirmed with T-Mobile that this requires an IMS SIM card, which they have just shipped to me for free (Arrives Friday). Other than that, it should be handled at the application level.
This may be of some use to someone:

Hows Dev support for the s3?

I'll probably end up upgrading around December but, I've been curious as to what the current state of dev support is for the s3.
I've heard there are a number of problems with getting the NFC to work and I was wondering if this is local to the S3 or if it applied to all phones with NFC.
It doesn't apply to the galaxy nexus.

Can't speak for anyone else, but NFC works fine here (running CM10). Maybe it's another model of S3 that's having issues?

I'm not entirely sure which is actually why I felt the need to ask.
The S3 is a pretty nice piece of kit that I may pick up in Decemberish.. but, I'd like to make sure it can mirror my captivates longevity in terms of dev support.
Its a flagship Samsung phone. Of course there will be prolonged dev support.

Because the Galaxy SII has enabled the nfc in other countries, like here in Brazil? Its enable?

You could try to find a NFC-enabled battery for your S2 and / or ask in the S2 forums.

The battery adds the nfc-antenna. Not the nfc-chip. GS2 with nfc chip in 6 countries, as far as I know. Not in Brasil.
At www.nfc-phones.org more info.
What's the model # of your sgs2? For instance I have NFC and the i-9100p does as well. There are some other variants of the i-9100 that are basically p versions. Do you have any RFID or NFC passport etc. That you could try and use it to read some info off it. Obviously it won't give you vital info off a credit card w/NFC or what not but you will pick up some information. And yes you need the NFC battery, first place you should look is on the battery it will say NFC towards the top.

NFC not working on device?

Guys do u have any idea why nfc not working in this device...
Z- Device Test says device have NFC .. but not working with any ROM...

From what I've read, not all S2 have NFC built in them...
"Samsung's Galaxy S II Android 2.3 smartphone was launched at MWC 2011. The Galaxy S II is available in both NFC and non-NFC versions, and most are the non-NFC version."

If you are using the factory battery you should be fine.
I believe the NFC antenna is part of the battery, I have three batteries and two nfc works and with one it does not. So I am pretty sure that is correct, but if you have a factory battery that should not be your problem.
I have used CM 10.0 and I am currently on SlimBean nfc worked on both for me.
