[Q] Using the Modem of this X with ATT's X? Possible?

Just curious about this question - because I would really want to use this with T-Mobile.
So, a few days ago I noticed that an aquintance of mine was using an ATT Samsung Note with T-Mobile. I asked him - but you are only getting Edge (2G), right? So he says - "No! I flashed the GSM version modem, and I am getting HSPA+ (4G)", or whatever you call it.
I was shocked! Amazing solution.
Do we have this?
Thanks

No. The AT&T model is completely different in terms of SoC.. their radios will not work for us. You can do like I am and use it on T-Mobile with an accompanying hotspot. Really not bad.

Thank you ! So making calls, texts, MMS is all fine, but DATA will only work on EDGE (2G)?
Also, what is "hotspot"?
Thanks again!

Yes sir, and I have found 2G is not nearly as bad as I once thought. A hotspot is just a device that gets 3G and broadcasts it as a wifi signal that your phone can use for data. On the T-Mobile website they are under "Mobile Broadband"

[Q] download data and talk on phone at the same time?

I am thinking purchasing this phone in the next week or so and I have a question for those that already have it. I have had people (even from sprint) tell me that you can use the data with wifi OFF and place a phone call at the same time and some people (even from sprint) tell me you can't. Basically can you download a app while in a phone call with wifi OFF? thanks for your help.

Not on 3G. I hear its possible on LTE but I don't have it yet in my area.

I can confirm that simultaneous voice and data do indeed work only with LTE (and WIFI of course), and not with 3G.

Ok so if I have the LTE signal and wifi OFF it will work or if I have NO LTE but have wifi ON with a signal? just want to make sure otherwise going to get a different phone (dont want to spend $300 and not have that feature)

Thanks for the quick reply. where did you get your info? I see in your first statement that you dont have LTE in your area. just wanting to confirm this data with someone who has LTE because I live in an area with it.

There have been other folks in the forums who do have LTE and have confirmed that it works.....one example:

Also articles like this one and other posts like this one. There is a 14 day return policy with Sprint so if you're in an area that has LTE, you can test. If it doesn't work, return it within the 14 days and you're good.

Thanks again for the prompt reply, I had tried to do some searches and not found those results. Thanks for the links.

AFAIK the only sprint phones with SVDO on 3g are the Galaxy s3 and the EVO LTE.

If somebody had a gs3 in one hand and a note II in the other and explained everything about them, and the last thing they told me was that I cant post on my wall while talking on the phone with the note II. I would still buy the note II with all the features and power this phone has.

From what I gather the reason this only works on LTE or Wifi is that the data is used from those, the 3g is used for talk during the call so it can use its secodn set of of antennas for data.

There are other phones with Sprint that have dual cdma chips in them (ie LG Viper)

The 3g uses the same network as voice (ie CDMA) only one can use it at a time, either voice or data. However 4g wimax and 4g lte use a different network so therefore you can surf and talk simultaneously. Unless the phone has dual cdma chips in them to do 3g and talk simultaneously which few of sprints phones are equipped with.

ATT Note 2 work on Straight Talk ?

Was at Worst Buy today, they said would price match any online price for the Note 2, plus offer me free insurance if broken, or any issues.
I was gonna get the true international Note 2, but worried if it has issued or warranty problems, it would be much easier to just go back to Best Buy than to have to mail it off, out of the country.
So, that being said, I am on Straight Talk, I hate being raped by the carriers and handcuffed into outdated contract system. Would the ATT Note 2 work on my Straight Talk SIM ? Or does the phone need to be unlocked first ?
I never unlocked a phone before. But I always root and install custom ROM the first day I take phone out of the box. Does rooting a phone, automatically unlock it too ?
And how bout HSPA+ ? Straight Talk doesn't do LTE yet, just HSPA+ I know the ATT Note 2 is LTE, but does it also have HSPA+ too, or just slower 3G ?

You would have to unlock it, either buy scrounging a code or going to the carrier and asking for one. Rooting doesn't automatically unlock the device. As far as 4G I really dunno, but I'm sure someone will tell you.

I believe you only need to buy the att version of the straight talk sim. No need to unlock. Then you go on their web site and get the APN.

Thanks, so I am currently using the ATT SIM on Straight Talk. Just pop that in the new Note 2, and it will work right out of the box ?
What about HSPA+ ? Straight Talk doesn't have LTE. Does the ATT Note 2 have HSPA+ 3G besides LTE ?

It is not the sim from att. Its a straight talk sim made for att phones. You have to order them online. It uses att network and you would get everything except lte.
https://www.straighttalk.com/ShopSims is where you order the sim and there is more info on the service on the site.

On my international One X, I am using Straight Talk with the ATT SIM. In the Straight Talk package, there were three sims to choose from. T-Mobile, and two ATT, one regular size, and one micro/mini, which is what I am currently using.
So can I just take this mini ATT SIM from Straight Talk, and pop it in the ATT Note 2 from Best Buy, and it will work ? I don't need to have the phone unlocked ?
Thank you

Its already been answered and yes ITS BEEN A LONG time since ive even seen a UMTS on my phone. and also HSPA+ is still 3G.... Straight talk Uses Edge,3G, and 3.5G which is HSPA+
Also if the Note 2 only used LTE then people would not be buying it cause not all AT&T areas are LTE...

I am more than happy with 3.5G HSPA+, plenty fast for my phone needs, I just wasn't sure it was included in the Note 2, for some reason I thought was just standard 3G only and also LTE.
Most the time I am in a WiFi area anyways, at Home or Work Office, so LTE not a deal breaker for me.
Thank you

Good point, thanks for the answer.
Last question, since I am using the ATT Sim for Straight Talk, is there even any point to have the ATT Note 2 unlocked ?

I would, just in case your are in area where there is no at&t service and are on the Edge network. Not only that but unlocking is free!!!

Flashed Htc One ?

I am wondering if a sprint Htc One flashed to verizon would get as good of a signal and a verizon branded One?

Most likely not. Different carriers run on different frequencies.

But if they run off the same tri-band cdma freq. , or for example sprint run 800 and verizon run say 805 ?
Just curious is all.

That's LTE which isn't used for voice right now. The CDMA networks aren't even close.

.... That sounds wrong... Maybe their postpaid is different. From what I understand not only are the frequencies different version must sign off on every phone on their network...
After some research I've seen both sides being positive they are right. One constant though is that Verizon must sign off on every phone in their network. Perhaps their post paid works differently.... Or maybe I'm wrong

I used to run a Sprint HTC Touch Pro on the Verizon network.
I ported it over, but that was years ago.
Both 1x voice and evdo/3g worked fine.
Was a bit trickier to get 3g then it was the 1x but lte certainly won't work on a Sprint on Verizon.
I certainly wouldn't go buy one from Sprint though planning on getting the ESN to get passed by their checks.
That's all I will say about that aspect.

I'm not sure about sprint but the vzw one is global which means ANY network will work, but you won't get better data . I just popped a metro pcs Sim in my DNA and my son is using it with no issues except weak data .

just because a phone is global doesn't mean it will work on all networks. there are too many possible bands to acct for. You would need several radios, which would eat battery.
"Global" phones will work on the most popular bands.
As far as LTE, there is not a chip that has all the US bands.

Global doesn't mean that at all.... The Droid 2 Global doesn't work on all networks. It simply means it will work in multiple countries...

Radio

Okay this may seem entirely stupid,but coming from mostly Nexus devices I haven't had to worry about radio bands so please excuse me. If I was to flash the AT&T radio would it enable the bands that are not enabled now or is this controlled by hardware?

If your talking about trying to put an at&t radio on a different carrier phone like tmobile, verizon or sprint, dont do it. It will not change your phone to work on at&t because its the hardware that is different.
You can use a tmobile phone on at&t though I dont think you will get at&t LTE though, I think you will get the HSPA and 3g data.
If this is the case trade your phone off or sell it and get an at&t one if you want at&t you would be better off.

You can also dowload any radio apps from play store.

I'm receiving 4g and if I turn it to LTE only I never lose it. But then I can't make or receive phone calls. As soon as I switch to gsm/wcdma/lte I'm consistently switching between LTE and H+. Is there any way to get it to stock on LTE? Also, the reason I'm not selling it is we're getting 4G in my town on t-Mobile at the end of May but right now it's only Edge. So I'm using an unlocked T-Mobile one with straight talk until that happens. I'm stuck on contract with then because I have three phones to pay off,also everywhere else around me has t-Mobile 4g just not my town
