[Q] Which Note II to buy

Initially I thought there were two variants of Samsung Galaxy Note 2, N7100 and N7105(LTE) but it looks like there are more.
I checked the NOTE 2 at my local T-Mobile store and it was SGH-T889.
I am planning to buy a (no contract/unlocked) Note 2 with LTE support. I can buy the unlocked N7105 online but it costs $825.
I was thinking of buying the retail t-mobile SGH-T889 for $650 plus taxes but I am concerned:
1) T-mobile support told me that I will not be able to use any other SIM.
2) Even if I get it unlocked from (cellunlocker.net), will I get any carrier LTE coverage ?
I frequently travel (international) so would like to have a Note 2 which supports LTE for multiple carriers ?
As per this Anandtech, T-mobile note 2 was unlocked and it picked up ATT LTE.
Phandroid also confirmed that t-mobile supports LTE.
I had a chat with Negrielectronics support and they informed that n7105 does not support ATT LTE.
Experts, please suggest/confirm if the t-mobile note 2 will support LTE overall ?
Thanks
LTE are carrier specific in the US. US Lte are incompatible with international Lte. That's why there are different models gsm of iPhone 5.
Buy the Lte model for the place where you spend your most time.

Please what do you think? Please... N7100 versus T889(Note 2 T-Mobile)

Hi, maybe i'm planning to get Note2 T-Mobile. Please what do you think? Because my story is before my phone was Galaxy S2 T-Mobile using Straight Talk T-Mobile SIM card honestly got down speed in my area Philadelphia 11.5 Mbps:victoryi swear to God). Now because i was getting excited with Note 2, so i bought Note 2 N7100 international. Now I'm using Straight Talk AT&T micro SIM card is very-very sucks, down speed only 2-4Mbps!! Should i stick/keep my Note 2 N7100 international or sell it and get Note 2 T-Mobile (T889)???? But also i love:victory: development forum international device is always more thread than compare US device forum. If you were me , what you gonna do? Because all i know T-Mobile is getting LTE in 2013. Thank you very much. Appreciate.

if u looking for speed...you have to go with att or tmobile branded note 2. No international since us carriers got their own respective frequencies.

Debrand or Convert T-Mobile Note II to AT&T Note II

ok my question is this,
I am trading up an old iPhone 4s for a T-Mobile Galaxy Note II, is it possable to debrand or install AT&T rom on this phone to make it an AT&T phone?
or any kind of work around to get it running on AT&T LTE network
let me know
Thanks
P.S. i do not have the phone in hand yet so i am asking if it is worth the trade

I know the tmobile note 2 is capable of lte but.it's not enabled in the default firmware, and I'm not sure if the frequencies will be the same as tmo hasn't even started rolling out their lte. My guess is it's the same hardware, but I would do as much searching as possible before doing the trade. If it's possible, I'm sure someone here at xda will get it working if it's possible, but it hasn't been out long enough for any definitive info. (At least nothing I've seen)

It should run on the AT&T HSPA+ (3.5G) network with no problems (as long as it's carrier/SIM unlocked) as the phone should have the 850/1900 GSM bands that AT&T uses. I'm not sure about LTE...but I don't think it will work.

[Q] Confused about Verizon Galaxy Note 2 as a World Phone

Hello Friends,
I keep hearing that the Verizon Galaxy Note 2 is a world phone. Yet many people tell me that if I buy a Verizon Galaxy Note 2 then I can't unlock it and use it with ATT or straight talk with their SIM. I guess by calling it a world phone what I think it meant is that I can use it on GSM as well as CDMA networks? I am currently in the middle of a contract with Verizon, so if I buy a Verizon Galaxy Note 2 on EBay can I use it for the rest of the contract and then at the end of the contract unlock it and move to a prepaid provider like Straight Talk?

Not going to happen, my friend. One) AT&T Note 5 has a locked bootloader which won't allow software to be loaded that isn't signed by AT&T. If you somehow get the software to load, it will not boot. Two) The CDMA network hardware for Sprint is not present in the AT&T Note 5 which uses GSM network.
