Does anyone know where the NFC is located on the Verizon version of the G2? I was looking at some magnetic mounts but realized it could potentially disrupt NFC. Thanks in advanced.

Hello all, i have a Vibrant. but unfortunately in my area at&t only operates their 3g on the 850band, which the vibrant doesn't support. so ive been stuck on Edge for months now, and getting sick of it.
I was wondering if the internal cellular antenna could be swapped with lets say a samsung captivate. so that it could operate on my local 3g band? (without any horrible software issues).
thanks for replies.
I don't know if this is actually possible, but I wish it was. That way, I would my antenna with the one in the Galaxy S 4G. I guess you'd have to find someone with that type of experience.
As of now im guessing it isn't, been searching everywhere on the net and i dont think its even been attempted on any android phones, I have learned that the cellular antenna housing is in the hump on the bottom of the phone. may disassemble it and take a look.
EDIT::: this is completely possible, however, i cannot find a supplier or place to buy a compatible chip that works on all bands....
ANYONE lemme know where i can. please and thankyou
I am from India and the version of Galaxy S2 that was released here doesn't have NFC. So I was wondering if anybody tried using the battery from the AT&T version of Galaxy S2?
I saw in reviews that the battery in the AT&T version of S2 contains NFC. If that can be used in the International version of S2, then it would be great. As with ICS if we have NFC, then we can use the beam'ing feature
It does not work on the international version there is a review in this forum that confirms the battery alone will cause NFC to work.
>>> Your answer is absolutely antithetic! <<<
Probable answer is :
"Old" GS2 seems to miss the PN65 or PN55 chip
Plus, the NFC battery requires 4 pins to operate.
As I am one of the lucky few to have a NFC-enabled Galaxy S2, I can't tell, on the contrary, how much battery pins do "regular" GS2 have. If there are only 3 installed, chances are that the chip itself isn't installed, and that adding a NFC battery with a NFC "ANTENNA" (>> no chip in the battery!<<) will just...make your GSM reception worse? lol (doesn't know)
Your best bet is on SIM-CARD-BASED-NFC, but this will have to be with your MO
hey did anyone followup on this...?? if a nfc enabled battery like the one in a ATT i777 would work in a i9100...??? as mentioned above that you need 4 pins... the i9100 does have 4 pins already so... dont think thats a issue... more this chip you speak of... how can one find out if their phone has that or not...???
also i dont think the nfc sd cards have really become readily available yet...
I have T-Mobile and I want to buy the International Samsung Galaxy S II. I understand that the International version does not support T-Mobile's 3g frequency band, and I would be limited to 2g speeds. However, I was wondering if it would be possible to buy an external antenna to be able to use 3g speeds. Or even better, is it possible to replace the internal antenna?
No and No.
DO NOT DO THIS UNLESS YOU WANT TO KILL YOUR GS2.
Sorry for the bold, but despite there being no rhyme or reason for it, I came across a thread which illustrated this fact from multiple people who tried external antennas, and here's what happened. The antenna worked, they thought all was good, then they disconnected the antenna, no signal. EVER again. I guess what happens is when you plug in an external antenna it pushes some contacts apart which breaks contact with the internal antenna permanently (supposedly a few that were very handy with a VERY tiny needle were able to fix it). Don't ask me why Samsung would design it this way while leaving the plugs exposed but that's what I read. Just wanted to make sure you didn't find out the hard way
In other words, the jack is there, and you can find adapters for those jack(s), but you really don't want to, unless you want to ONLY use external antennas for the rest of time (not most people).
EDIT: Whoops, forgot to add the most important part. Antenna has NOTHING to do with the fact that the radio doesn't support t-mo's frequencies. It's like having an antenna designed for HDTVs, and hoping to get hdtv on your standard def tv. Antennas don't "translate", they're all just fancy coathangers.

"antenna has nothing to do with GSM OR CDMA bands." its the radio chip that does the work.

Understood, thanks for your help guys. Is there a way to mark this as [Solved] or something?

Yes. Edit your first post to an eye-popping "SOLVED"
Hey,
I have an S4 but I activated it with my Note 2's SIM. I've heard that the S4 uses an NFC-SIM, does that mean without a new SIM i can't use NFC? Or are the NFC capabilities built into the phone itself?
Thanks guys!
I don't think it's a nfc sim. The s3 and s4 both have their nfc in the batteries. That why you'll see replacement batteries with and w/out nfc. I do know the nfc tagging is a different version with the s3 and s4. None of my nfc tags from my s3 work with my s4.
I think the NFC SIM is just an extra layer of security for their ISIS mobile payment app. I don't think it's required to just have NFC capabilities.

The NFC SIM is only needed for Isis.
The Broadcom NFC module is soldered to the phone's mainboard. The antenna is integrated into the battery.

Yeah, Mifare Classic tags are probably what you had and worked with the S3 (and many other phones) but don't work with the Broadcom NFC hardware on the S4. Stick to NTAG203 Tags, Topaz 512 Tags, or any tags that adhere to NFC Type 1 or Type 2 protocols and you'll be fine.
Like others said, the hardware is in the phone and antenna on the battery so you'll be fine!
One of a pair of LG V10 between myself and wife is having boot-loop issue, and to avoid further disasters, I bought a pair of G5 F700L as interim solution couple days back. Never-the-less, the NFC on F700L doesn't seems to work. anything I could do to confirm my hardware is supporting NFC, and/or respective NFC chip is assembled onto our F700L
Based on OS, NFC function has turned on [Icon on menu bar] but it can't read/write any NFC tag. Please share with me if you have any hints
