[Q] Any good place to sell my GS2 i777? - AT&T Samsung Galaxy S II SGH-I777

I have one I do not use due to it being GSM and want to get rid of to buy a one I can actually use[Galaxy nexus CDMA].
I put the listing on Ebay[expired],Craigslist and Swappa. I would try the XDA forum as ive been told but there I cannot post there due to the new restrictions. Can you help out XDA?

yes sorry WCDMA , and they only give me 137.80 for it :/ not enough for a used galaxy.

I'm confused what the GSM galaxy nexus will offer over the GS II. Don't they both use the same HSPA+ / WCDMA frequencies, if you get the GSM version?
Regardless I think you will be extremely lucky if you can find a way to swap a Galaxy S II for a Galaxy Nexus. If you ever do find a way that by some miracle gets you a GSM Galaxy Nexus for a i777 straight over, do let us know.
XDA does have a marketplace forum for buying, selling, and trading.

I don't have a CDMA network to use the phone right now its just sitting there. I have verizon thus my need for a GSM phone. I know it does but with the new restrictions I cannot post or even look at the forum :/

I think your confused. You cant use any GSM phone on Verizon. Unless maybe its unlocked? Verizon is CDMA. Along with Sprint. GSM can be used with ATT and T Mobile. i777 is for ATT. Unless you have the International version i9100. Then you should be able to put a T Mobile sim in it.

Wait a second, so your saying I CAN use my i777 on verizon?its the AT&T model. I was told by AT&T that i cannot use this phone on verizon.
Edit: Nvm. So I need to purchase a verizon nexus. Ok. well I guess I still need to sale this phone.

Yes, you need a CDMA/LTE Galaxy Nexus for Verizon. The i777 will not work on Verizon.
None of AT&T's LTE phones will work on Verizon, even if unlocked. What AT&T calls 4G that isn't LTE, their HSPA+, is also referred to as WCDMA, plus their 3G is called WCDMA, but its not CDMA like Verizon or Sprint. If that wasn't confusing enough both AT&T and Verizon use 700 MHz LTE, but they are not using the same section of the 700 range so they are not interoperable. Unlike EDGE (2G) that is interopeable on AT&T vs T-Mobile. And some regions of AT&T and T-Mobile use the same 3G frequencies, so some 3G phones have limited functionality on both GSM networks.
Basic rule of thumb, for best results get a phone specifically made for your carrier.

Yeah it was a gift so i didnt really have a say in it. but thanks for the info none the less

I just brought the price down to 300 on swappa incase anyone is interested.

These phones aren't going to sell for nearly what they could a few months ago sadly. U can grab one for almost nothing nowadays by signing up for new contract. I got mine for a hundred. But u see them for as low as 25 bucks.

galaxy s II works on tmobile 4g network usa??

I am really itching to get this phone, as my contract is going to be done within weeks. I know that the EU version wont support tmobile 4g. How about the Canadian version??? the bell/ virgin galaxy s II 4g. Would this version work tmo usa??
Check the bands. Google it. If they're the same then it will work. AT&T's 4G network will work with European and Canada's will also I believe.

that's the problem, I am new to this stuff and willing to learn. Let's start with what BAND is, and how do I check that BAND.
I am not 100% sure. But I believe that it well not work on T-Mobile USA 4G network. It uses different frequencies. If the SGS II ever comes out on Rogers then it will work on T-Mobile USA.

You are right. And once the merger goes through the T-Mobile 3 and 4g phones wont work on 3 or 4g. This was already stated by att and tmobile

By that time the Galaxy S III will come out lol. But I will definitely love the HSPA+ speeds on my SGS II.
If you really want it either:
1) Switch to AT&T, you will get 4G speeds
2) Wait for the Samsung Hercules to come out on T-Mobile (Should be this or next month)
In the end, all people who buy T-Mobile phones now will eventually suffer later on. ;D

Dude,
It works very well! I have the AT&T Note... I unlocked it ($25 on ebay, I prefer this method as the seller has a reputation to protect). I then had it rooted, then flashed over to T-Mobile (http://rootgalaxynote.com/).
I did a test on the $30 - 1,500 minute plan (only 30 megs of data) to see how it works. I did this before flashing the modem and the 2G/Edge doesn't work well at all for the Note. However, after flashing the modem, it screams on TMO's 4G.
Good luck to you, but flash it and don't look back!

But just as a heads up, the exynos chip in the international version is not LTE equipped. So, if you get the international model it won't work on Tmobile's 4g bands even if you flash/hack/pray to the cell gods or anything else to your phone.

I'm not totally sure but, I believe if you get the international it will work on tmobile's hspa+. You shouldn't have to get the AT&T version if you just want to use the phone on tmobile and, are ok without LTE. Hspa+ is still very fast.

T-Mobile doesn't even have LTE so it doesn't make a difference.
The AT&T Note is the only one that works with T-Mobile 4G which again, is not LTE.
Also, no the international version does NOT get T-Mobile hspa +.
The international version ONLY gets EDGE on T-Mobile.

Both white and black are the same, yes you will get 3G and 4G coverage on at&t since 4G is hspa and at&t supports hspa.
No this phone doesn't have lte and just a heads up, though you will get 4G, it might not be as fast t-mobile from what I've heard, their HSPA isn't that fast but still pretty decent.
I appreciate that.

I used to work for Business End User Care for AT&T. As of the time I left (november), if you placed your sim in a smartphone and used it for about a day the system would add the lowest data plan and send you a text message indicating it had been added to your account. Even if you were using someone's phone while your "feature phone" wad being replaced, it was required. I've had to read that section of the TOS to many, many angry people. I would call and confirm just to be safe.

DO NOT CALL to ask..... as they won't know the answer, and might put a note on your account to force a data plan(well, you could call and ask on someone else's phone without giving your account number)
the primary way (so far that I've seen) that AT&T detects your smartphone is via IMEI. Secondary might be you using >100GB/month, connecting to their 4G APN settings, going to a store for help and letting the customer rep see that you have a smartphone
does AT&T have your IMEI? probably not.... AT&T has IMEI of all of their smartphones, so you can't use an AT&T smartphone. You can try using an (unlocked) t-mobile phone, but might not support the right 3G/4G bands that AT&T use. You can try international phones, canda phones(from Bell, Telus...). WARNING>>>. AT&T might have your IMEI because the manufacture gave them the IMEI(See Google Nexus phones), inference from branded phones that they carry(eg Phone is sold/branded by AT&T and t-mobile... AT&T gets a list of their phone IMEIs that might include t-mobile's IMEIs), screwups(Samsung Note overseas was misentered as a tablet on AT&T's network, white i9100 Galaxy SII is misentered as a Blackberry on AT&T's network)
The link at the end of this post gives a guide to what phones are 100% compatible(3G/4G on 850/1900) on AT&T's network.
According to this, the T-Mobile Amaze 4G is compatible with AT&T 3G/4G, but I have some confusion on the 850/1900 mhz band for the 3G/4G data, trying to sort it out(last few posts on that thread)
Guide to what phones are 100% compatible with AT&T's network
anyways, quick update
got a T-mobile Amaze 4G to play with
(with unlocked bootloader, S-Off, Super CID and SIM unlock, all available on this forum), works on AT&T 4G (HSDPA)
speeds right now ~ 1000 kbits/s up/down, hard to test because my location is spotty

Sprint Galaxy S 3 (USA) vs international galaxy s 3 question

Here is my issue. I am currently in the US. I might teach ESL overseas in Korea in January. I am not sure which phone to get. Will the USA one work over in Korea? Will thew international one work in the US?
It could work but Sprint has the radios locked.
Would developers be able to get them unlocked?

Just a side note, HSPA+ is not 4G. It's still 3G. LTE/WiMax is 4G.
so which companies will it work with 4g/lte? Will it not work with Sprint? Anyone know any deals for the international version?
Sprint (and Verizon) is on an old CDMA network while the majority of the world is on GSM, you know, operating with a SIM card. If you're set on travelling, it's better to get any of the GSM-variant, that way, you can just pop in any sim card from any major carriers all over the world.
I currently have a photon which has a sim card slot in it. So the Galaxy s international wont work on Sprint? Damn I want to keep my SERO plan lol. So where can I get an international verison from? Also would I have to pay full price for it?
Does the photon has an active sim card in it? I'm assuming no. I've never used a dual-mode phone before (nor am I familiar with how they operate on different networks), so I dont know the ins-and-outs on how to get it activate for a GSM carrier.
Damn, now i have a headache just trying to figure out how it works to have an intl GSM phone on a network that is predominantly CDMA whom happens to offer a dual-mode phone on their network

The SIM in the Photon is just for roaming. Sprint does not use SIM cards - even their LTE phones have them embedded rather than user-accessible.
As the Sprint Galaxy S III is not a 'global' phone - i.e. does not have both GSM/UMTS and CDMA radios - do not purchase it if you have any intention of using it outside the US. CDMA is no longer a global technology.
Confuses me a little that people spend so much on devices without checking what networks they support. Ho-hum.

Works exactly the same for me using an AT&T SIM in the T-Mobile HTC one. The other way around, I get less HSPA+ service using an AT&T SIM in a T-Mobile HTC One.

No. The AT&T one doesn't fully support T-Mobile while the T-Mobile one fully supports BOTH T-Mobile and AT&T.
For people who don't want CDMA-based service, the T-Mobile version is the best one to buy for compatibility.

Are you sure about that, Maybe the AT&T version needs to be unlocked for it to work on T-Mobile's HSPA+ Network. I hope like hell it does because I would like to have the 64gb version working on my Network of choice, T-Mobile of course.

This has been discussed to death on the boards.
All the phones have the same internal radio hardware but what's been flashed to each device is different.
i got a att version unlock, big mistake for tmobile. i flashed tmobile rom and radio. alot of places in new york i get 2G which it was constant 4G with my note 2. Place where i get 4G i only get 7mbps. while with my note 2 i was able to get up to 18mbps. Order the tmobile version will return this one. The only reason i bought this is because they had it locally in ATT store while tmobile htc one is on backorder and not avail in any store.
Unfortunately Samsung doesn't just make the same model for both I would imagine it would save them money also but att phones work slow on T-Mobile but other way around your golden
