Correct me if i'm wrong but for my understanding our international tab supports hspa+ 21 which is considered a 4G technology why is it that they called our tab as 3G then ?

doesnt hspa+ is 3.5G?
for my understanding 4G is lte or WIMAX2 at this moment
4G is the deep blue sea.
"3G" and "4G" are just marketing terms really. Carriers may market HSPA+ devices as "4G" in order to get more sales from the average/ignorant consumer, but HSPA+ isn't a "true" 4th generation mobile technology in the same way that LTE and WiMAX are. Instead, HSPA+ is more of an evolutionary refinement of UMTS, much like how EDGE is an evolution of the previous (2G) GSM/GPRS technology before true "3G."
Don't get caught up in the marketing gimmicks of the 3's and 4's and G's. Instead, be educated on specifically what technologies are being used, and what pro's and con's each offers. I'm not going to go over that here, but I will say that Google is your friend; use it.
In other words, try not to think of the P6800 in terms of being a "3G" or a "4G" device. Think of it exactly as an HSPA+ 21mbit device. No more, no less.

Because (surprisingly), outside of America 4g doesn't really exist yet in any meaningful sense. Everyone knows and uses 3g.
Exactly. Outside the US 4G is what LTE/LTE Advanced is. HSPA/HSPA+ is only an enhanced 3G specification.

Ok what to make of this? Will this run on CDMA or not? Is CDMA synonymous with LTE?
Link here: w3androidcommunity.com/samsung-galaxy-s2-for-preorder-at-getgoods-20110301/
Quote: The Galaxy S2 will run on 4G/LTE networks on HSDPA and HSUPA in a quad band configuration under GSM or dual band under WCDMA.
I can't speak to whether or not it will run LTE as I don't know how Verizon does this or for 4G for that matter as I don't know much about how that works... but the international version (only one available to north america by ordering from abroad) is NOT CDMA. It requires a SIM for it to work, CDMA is non-SIM
Edit: If I am wrong don't crucify me it's just my crude understanding
Its the way I understand it too but the dude has the phone in his hands. Granted, this doesn't make him an expert but it makes me wonder.

The SGSII version that has been announced is a GSM based phone meaning no CDMA.

CDMA does not mean LTE. This is not a LTE phone as it doesn't have the LTE bands to support it.

They probably meant there will be different versions of the phone. One version with quad band GSM (UK version about to be released) and dual band CDMA version that might come out in the future.
That being said, the SGSII uses HSPA+ 21Mbps speeds. Bell Mobility in Canada labels 4G with HSPA+ up to 21-42 Mbps. Check with your carrier for their network speeds. Carriers label HSPA+ with 4G to attract more customers but this is really not 4G, HSPA+ it is an evolution of 3G (basically higher speeds).
Hope that makes sense...
It does make sense. I just wish they'd announce that it's coming to verizon with lte capabilities already. Even if they said it'd be a year, at least I'd know. Thanks for the inputs.
yeah bell is stupid like that... in reality it's more like 3G+ or 3.5G
So...it's probably safe to say that everyone in this forum knows about the 7 year roaming deal that AT&T has signed with T-Mobile. Does anyone have any ideas on when that will happen? And the big question...will the iPhone technically be able to be used on 3G with T-Mobile? Yes, it would only work while roaming, but would it not work for some reason? A T-Mobile rep brought up the question and I thought it was a good question. I'd like it to bring in revenues for T-Mobile...but I love my fast speed I get with T-Mobile, and 10 gazillion iPhones would do nothing but harm for that.
**Updated** Please, if anyone can check their Android phone (via *#0011#) and post if it says band II along with the city you're in at the time that it shows it! We need to find out which cities have been refarmed to 1900MHz for 3G/4G.
So, go forth and discuss
List of pentaband UMTS devices:
T-Mobile Galaxy S II (T989)
Nokia N8 and N9
T-Mobile Vibrant (T959)
Galaxy Nexus (HSPA version)

It'd be 2G roaming. The carriers' 3G networks are incompatible. While AT&T devices will work on T-Mobile's EDGE data, it shouldn't be common enough to impact our speeds much. The only way this could possibly happen is if both AT&T and T-Mobile started selling exclusively pentaband HSPA devices. Which would be awesome on so many levels.

The OP specifically asked about the iPhone, which is unable to get 3G on T-Mobile's network. So if an AT&T iPhone were to roam on T-Mobile's network, it would not get 3G speeds.
Edit: The Galaxy Nexus is also pentaband, and so are the Nokia N8 and N9. The original Vibrant is also pentaband.
The Skyrocket is also pentaband, so I'll be able to mooch off of 42.2mbps HSPA+ when I get an LTE throttle. LOL

Skyrocket has a more advanced modem.
Well, it's really just the T-Mobile radio with LTE slapped into it, so yes, I do have 42.2Mbps.
has anyone tried the AT&T skyrocket on T-Mobile? Does it support HSPA+ AWS? AFAIK, only LTE works on AWS for this phone.
Thanks everyone for the phones. I've been busy and couldn't really update the thread. The current gen iPhone doesn't have AWS, yes, but since the roaming agreement is UMTS, wouldn't that allow T-Mobile devices that have the ability to roam on 850/1900 bands the ability to connect to their 3G network? So jailbroken iPhones that are activated on T-Mobile could roam over to AT&T 3G, it's just that it isn't likely that AT&T would allow it.
Am I right in my assumption?
I don't think AT&T would allow it, honestly.
Edit: According to GSMArena, the Skyrocket doesn't support 1700/2100 HSPA+. Only 1700/2100 LTE.

Thanks for the heads up. And when the others in the thread said the Galaxy Nexus, they were referring to the European version, correct?

Over at the T-Mobile SGS II forums, when I flashed a T-Mo SGS II modem, I gained access to 1700/2100.
All I need is a T-Mo SIM card to test if it'll connect to 3G, which I don't have.
I have the GSM Galaxy Nexus so naturally I am quite excited for this.
But the question remains... Does anyone have the slightest idea when this service will go live???

It's not as simple as touching AT&T, and roaming.
You have to be in an area where there is COMPLETELY no T-Mobile signal, it can't even pick it up when you scan for it. Then, and ONLY then, will the SIM allow you to verify it on AT&T's network for roaming.
With AT&T's larger coverage footprint, you T-Mo users should have some nice coverage while traveling.

Skyrocket has the same modem as the T-Mo SGS II, except with LTE attached.
It's a different modem number, but other then LTE, it's all the same.
So yes, I can.

Where do you get your information? I thought that's how it has always worked prior to this new roaming agreement. I spoke to a T-mobile store rep (not the best source of information) and he told me that iPhones on west coast had 3G access.

I've heard that T-Mo is doing some spectrum refarming on the PCS band...in other words, 3G is starting to pop up in certain markets on the 1900MHz band
I know this has been rumored before, but here it is straight from the horse's mouth.
http://blog.t-mobile.com/2012/03/13/t-mobile-expands-4g-network-to-new-cities/
Snippet here:
We are also going to make more effective use of the spectrum we already have by refarming a portion of our 1900 MHz PCS spectrum to support HSPA+ services, which frees up additional AWS spectrum for LTE
If I am not mistaken that would also make our Galaxy Notes compatible as well! Which would make me very...
damm
that would be Great!
Tmo USA's 1900mhz band is for 2G. So all they are saying is that they will use some of their 2G spectrum to expand their HSPA+ (1700mhz) and LTE (700mhz) network.

Taken from the article...
"Will refarming make your network compatible with the iPhone? And will you stop offering 2G services? A nice side benefit of the refarming effort is that our 4G network will be compatible with a broader range of devices, including the iPhone."
That would be a great way for TMo to steal some customers from AT&T and add to their user base when the AT&T users bring their own device (BYOD), since their plan prices are better.

Yah, and at least in my area T-Mobile has better reception & faster data speeds. So, I will jump over as soon as this becomes a reality. *fingers crossed*
This alone will bring Tmobile to 3rd. If they also market themselves as a carrier that isn't afraid of being a dumb pipe, they will foster despite not having any hero phones of their own.
Here's a new post over on the T-Mobile forums.

Hi all,
I have an unclocked Samsung Galaxy Note I9228 from China Mobile. I was hoping to use it on At&t's 4g network but am currently only getting the edge network. I have read news articles talking about the radio chipset:
"Spreadtrum's SC8803G enables TD-SCDMA, EDGE, GPRS and GSM operation and supports TD-HSDPA at 2.8Mbps and TD-HSUPA at 2.2Mbps." - Streetinsider.com
Does anyone know if I can receive At&t's 4G network? If so, what are the steps to configure the device? Thanks in advance!
That's a TERRIBLE 3G data rate...!
If the 3G speeds are not that great, does this mean that the I9228 cannot support 4g?

The "TD" refers to Time Division multiplexing as opposed to the Code Division multiplexing used by UMTS/HSPA standards in other parts of the world, including AT&T. Specifically, TD-SCDMA and TD-HSDPA, are both proprietary technologies developed exclusively by and for China. There is nothing that you can configure on your device to make it compatible with AT&T's 3G/4G network; it simply lacks the required compatible hardware. Buy an N7000. That's your solution. Sorry.

It's important to know exactly what you talking about when getting caught up in marketing catches phrases like 3G and 4G etc.
AT&T's high speed network uses two different technologies, HSPA and LTE. HSPA is more of an evolution of UMTS, kinda like how EDGE is an evolution of GPRS. LTE, on the other hand, is a completely new technology from ground up. As it stands, LTE is easily about 5 to 10 times faster than HSPA on average, with speeds in the 30 to 60mbit range.
AT&T markets both technologies as "4G," even though only LTE is considered a "true" 4G technology.
The unlocked N7000 does not have LTE capabilities, but it does support AT&T's HSPA, which realistically should yield download speeds around about 3 to 9mbit. Is it fast as LTE? No, not by a long shot. Is it "fast enough?" For most people, yes, but that's up to you.

Close. The TD refers to Time Division Duplexing, i.e. the same RF carrier is used for both uplink and downlink transmissions.

Looks like we will be able to use 4g hspa+ on the 1900MHz band. Im pretty happy about this since the international version is much better than the U.S version in terms of the processor.
While upgrading coverage inside the West side of the Moscone Center, T-Mobile has also deployed 4G HSPA+ service in the 1900 MHz band to test the live network on a small scale. As part of the company’s previously announced $4 billion network modernization effort, T-Mobile plans to launch 4G HSPA+ service in the 1900 MHz band in a large number of markets by the end of the year, which will make our 4G network compatible with a broader range of devices, including the iPhone.

Careful here.
Yeah, as much as I'd love the international version for dev support and possible "more future proof" because of the exynos quad core, I'm hesitant to rely on Tmo's "future plans". I have screaming 1700Mhz in my neighborhood and consistently get 9mb/s down on my GN. I could only imagine what a HSPA+42 device would get. Probably 25mbps lol.
Why start a new thread it has been beat to death... it's planned for end of year... period... it's a big country, only few markets will be tested...and how dependable is it going to be while they are building, testing,and stabilizing it at the same time...
I remember this being announced around Christmas time if not earlier... it's not happening over night
