[Q] Note 2 - 5 Models already !!

So Galaxy Note 2 has now got 5 models to be released shortly, here is the breakdown
International : GT-N7100
Verizon : SCH-I605
TMob : SGH-T889
Sprint : SPH-L900
AT&T : SGH-I317
Thanks to Evan
AT&T : 850 cellular/1900 PCS GSM/UMTS & 700MHz (Band class 17) LTE
Verizon : 850 cellular/1900 PCS CDMA/EVDO & 700MHz (Band class 13) LTE
Sprint : 800 SMR/1900 PCS CDMA/EVDO & 1900MHz LTE
T-Mob : 1900 PCS GSM/UMTS & 1700/2100 (AWS) UMTS
Seems like they will all have Quad Core Exynos with a seperate LTE chip
My question is does that mean we will be having five different model forums, or is it possible to have only the current one for all the models, since they are pretty much the same Exynos + LTE.

I hope not......i hope they each have their own

Interesting question.. I think that as far as you dont flash a different radio(assuming that the main difference its the band) you would be good to go.. an example of this happens on the Gtab 7+ variants.. mine its 6800n(different band for south america) and i can flash any rom from the other variants 6800/6800h no problem.. just keep my radio..

There is two international versions:
N7100: 3G only
N7105: LTE
And yes they will most likely get the same forum with seperate development sub-forums.

One thing I wonder about, here in Sweden the LTE frequencies is 800/900/2600 MHz.
It means that when we get LTE it will be different from the international version and developer support will be non-existent or can we flash international roms if the only difference is LTE frequencies?

I still can´t understand the fact, taht every provider in the US needs its own model...whats the thing about it? Everywhere in the world = same model over hundreds of provider...

Each carrier wants to have complete control on what is in the phone and what they want to cripple. I'm heavily considering the International version this time but will wait for all the details to come first.

Hm,...sorry for noobing, but: My international S3 is a quadband model and works in the US as well...which frequencies do you refer to?

My question is will be have different development for
N7100-64GB and 32GB and 16GB....... Will they have different forums or same

Also, UK has just released LTE on 1800mhz band, any idea if Note 2 will support it?
(it would be really really stupid from Samsung, if they didnt, but it's still a possibility)

carriers use different frequencies and network technologies (CDMA or GSM)

I hope they do have a separate one, as they did with the Galaxy S3...it was really confusing at times.

Soooo, its (worldwide) just Verizon & Sprint (or let´s say it´s JUST sprint) that causes this fragmentation?

i have never bought an international version either but if it comes out sooner i will since i would like to travel a lot...
will the international version for any reason not be as good as the eventual verizon version for me in regards to anything....4g speed, roming, etc...
thx!

No need for me.to get the international versions anymore I guess,since the processors are the same.

No, there is also fragmentation between AT&T and T-mobile versions. They use different frequencies for 3G (HSPA+) so an AT&T phone will not work on T-mobile and vice versa. You'd need a pentaband phone (e.g. Galaxy Nexus) to cover AT&T, T-mobile, and international gsm networks.

[Q] Will the I9305 work on Tmobile's LTE network?

I have done an extensive search both on Google and XDA Developers, and could not find an answer to my question.
I know that Samsung has released an LTE compatible version of the S3, the I9305 (LTE 800 / 1800 / 2600). So my question is, when the LTE network becomes available and more prevalent for T-mobile, will I be able to get LTE speeds with an unlocked I9305 S3? Thanks.

As I recall, T-Mobile doesn't offer LTE. Or maybe they have started recently and I just haven't realized it. But nonetheless, you can use the i9305, on T-Mobile seeing as it is an unlocked gsm phone. So it'll go as fast as T-Mobile will let it.
EDIT: Just kidding, T-Mobile DOES have 4G LTE, supposedly the fastest out there too.

That's not all there is to it... They launched LTE-Advanced right off the bat. It is highly optimized over LTE revision 0.
OP, you would not even get HSPA+ on that phone if there isn't support for the 1700 band but you definitely will not get LTE based on the bands you posted.

Thanks for all the responses, this is good to know. I was always leery about unlocked phones claiming to be LTE compatible... this is why I would prefer buying a t-mobile specific LTE phone so I am 100% certain I will get LTE speeds.

T-Mobile is unique because they use the AWS 1700 band for LTE and 3G/HSPA. Verizon and at&t use 700MHz for their LTE which is the problem. We should start seeing a bunch of phones launch with AWS LTE this year. I would just wait and see what comes down the pipeline.

[Q] Cel-Fi Signal Booster + Verizon S4 + TMobile Sim Card = HELP

Hey Guys,
Not sure where to ask at this point, but I know that there is a Verizon forum for the S4, but this is more T-Mobile inclined question.
My mom was given an S4 at her job from Verizon but I convinced her to give it to me since I wanted it and I gave her my Tmobile Note 2.
I put my sim card into the Verizon S4 and configured the APN setting so now im getting faster data speeds with the Verizon S4 than I was with my Tmobile Note 2. So everything works but the phone is in Global mode, which I dont really care at this point.
My question is though, how can I get the Verizon S4 to connect to the Tmobile signal cel-fi booster that I have. I have no service at my job so therefore I obtained one of the boosters offered by Tmobile, works great with my Note 2, but the S4 does not recognize the cel-fi booster.
Please advise...

I guessing the cell fi thing is for tmobile phone only. I'm sure tmobile don't want just anyone to use their products.
It's probably a firmware deal and not the SIM that recognized the cell fi.
☞ Sent from here☜???

Yes, I definitely understand that, but I am using a TMobile sim card, logged into Tmobile towers, using Tmobile 4G LTE network, but the hardware/firmware is Verizon, so that is why I am asking if it is doable to get this working? Perhaps if flashing a rom or something?

Your best bet is to call T Mobile tech support and ask them. You've got a really obsscure question that probably has to deal with the frequencies the 2 devices communicate on that no one here has probably ever dealt with. T Mobile is going to be the quickest way to get this answer.

The T-Mobile cel-fi operates at the 1700MHz aws frequencies. According to this thread they are not enabled by default on the Verizon galaxy s4. So that's why it's not picking up the signal from the cel-fi.

Guys,
I work for Cel-Fi - it looks like you are correct.
The RS2 Cel-Fi (the latest one) will boost 2 bands: 1.9GHz (aka PCS, Band 2) + AWS
BUT the older RS1 (we dont sell it anymore) will only boost AWS and not Band 2...
Check here for details on the Bands 2 and 4, and here for definitions of the bands...
It looks like the S4 gets 1900 band 2 (specs S4 for T-Mobile UMTS: Band I (2100);UMTS/HSPA+: AWS Band IV / 2100 / 1900 / 850;Band II (1900);Quad Band GSM;LTE)
Let us know which Cel-Fi you have...
Regards,
Laurent

I have the RS1 (older one) got it for 90 bucks on ebay
Works great!
And since you work for Cel-Fi, does the RS2 model boost the LTE signal for T-Mobile or not? From what i am reading, it does not.

Sorry for my ignorance but how is the Verizon Galaxy S4 able to connect to T Mobile let alone LTE? Is Verizon S4 a pentaband phone? I think my knowledge is outdated but I was under the impression that Verizon uses CDMA

They do, it switches to global mode (GSM) when you insert a non-verizon sim.. Most CDMA smartphones have this capability nowadays, which they did not before.. Verizon is the only carrier I know that does not lock the gsm radio on their phones, I think Sprint's phones are sim locked

[Q] ZE551ML at&t APN settings

I am not getting 4G LTE. It is staying on H (hspa). I have the one plus one and get LTE.
The info online says this phone should have all of the bands required.
Any ideas.
Thank you

Check Settings - Mobile Network settings - Preferred Network Type and set it to LTE if you have this option and is not already set.
But I doubt that this is your problem. You bought the Taiwanese phone, didn't you? While OnePlus supports all ATT LTE bands (17, 4, 2), the Taiwanese Zenfone 2 doesn't support band 17 (nor ww model), which is otherwise typical for less inhabited aeries in the USA, but it seems that is widely used by ATT. Try the phone in the downtown or another city and you'll probably catch the LTE on other frequencies.

Yes I purchased it from Taiwan but all of the sites show so many bands for this phone. Asus does a terrible job with their model numbers. There are so many different versions with the same model number. There is a 4 g setting not lte and that is selected. I did pick up 4g while driving through part of the city.
Is there going to be a US model?
Thank you

Yes. There is a US model and its supposed to be released in the next month or so. The link below, click on specs, shows the LTE bands for each region. Clearly shows the Taiwanese model not having the 17 band.

That stinks. I took that page as it will work in all of these markets. Oh well

Where in US are you?

There are some areas in the US that are only on LTE band 17. I suspect that's OP's issue.

I looked at it and TW, WW and US all have 1700 bands if that's what you are referring to. If not can you shed some light?

The topic is about bands not frequencies. There is nothing such as 1700 LTE band. Actually both USA and TW phones work on approximate LTE 700 MHz but bands are different because uplink and downlink are different. So TW model works on band 28 and US one on 17.

I see now. Tnx for the quick response. Hopefully I'm not outta luck when the phone arrives tomorrow from TW. Do you think that flashing later on a radio or baseband will solve this issue?

It's not that simple. Luckily Intel chip supports all LTE bands. But they must be activated in kernel too. Maybe someone will find the method to activate the missed ones. Otherwise you are not so bad. With TW phone you are short of only one LTE band of four major in the USA, Europeans missed 2 of 3.

Frequency wise is matches everything AT&T needs, i just picked up my 4g/64gb TW model, i'll be playing with apn's to see if i can get lte to pop. Only getting H+ so far.
Correction, shipped with WW firmware, no 700mhz for us.

More - As posted above, this Taiwanese version is missing the LTE band 17. And there are some areas that this may be the only band available, so you will not have LTE in those situations.

Thanks so much.... I was having a heck of time here with my Zenfone 2 in Tucson AZ on T-mobile.... I was stuck on 2G... but updating the APN to fast.t-mobile.com and 2 reboots seems to have done the trick. So glad I don't have to EBAY this! THANKS AGAIN.... Loving this thing so far!

Well ****! This is where I am stuck win H+ on ATT.
No way around this huh unless someone does a new rom? Or is it hardwired?

how to use note 4 sprint on LTE bands 3 and 7 ??

Hello!
I have an unlocked*sprint*note 4 which I use outside the USA as a GSM phone with a sim card.*
So far so good.*
The problem is that this phone being produced forsprint*does not connect on 4G.
I have been reading about the possibility to change the NV values to be able to add LTE bands to the phone and I was able to change those values but still no luck.*
In my country, the 4g network works mostly on bands 3 and 7 (1800 and 2600).*
I am starting to think that probably the*sprint*version might have differences in hardware with other 4G capable phones.
Can anybody tell if there are any hardware differences between the*sprint*note 4 and other note 4 models.
Do you think that the*sprint*note 4 has what its needed to connect on 4G on the above frequencies?
If yes, what might be the right approach to try to resolve this.
Thank you for reading and since this is my first post on XDA please help me!
