I have searched through many posts and cannot seem to find many others with the same issues. I unlocked my TMobile US HD2 and have been using it on ATT. Now, I understand the 3g connection problem and how you're limited to Edge, but what I do not understand is that in the Band selector, there is the option for 1900/850. Isn't 850 ATT US's operating frequency for 3G? If so, why shouldn't this phone be able to connect?
you have the data bands and voice bands mixed up
its a quad band phone, for voice, but doesn't support all of atts data bands , only tmobiles , therefore, you get to use edge only on att, not 3g
know what i sayin?
Yeah. Makes sense. Explains why it doesn't say UMTS 850. Lol.
Thanks!
Does any one know if I can use the tmobile G2 with a canadian wireless plan if its unlocked. I have read about all that tri band stuff but its a little above my head.
Thanks!
T-mobile does not have the same 3G/4G bands as Canadian carriers (Bell, Rogers, etc)
You will only get EDGE. If you want 3G/4G go with an unlocked AT&T phone.
and if ive read correctly, you need to go to a carrier that uses gsm (because tmobile phones use gsm)
Umm, not sure what only getting edge means. Does that just mean no data, just voice and texts?

As of 2011 there are three levels of data speed that are used and the order goes like this:
4G
3G
EDGE
The speed decreases as you go from 4G to 3G, and EDGE being the slowest.
You will receive data, just not at blazing fast speeds.
From what I understand, T-Mobile uses AWS, of which three carriers here provide: Mobilicity, Wind Mobile, and Videotron.
It's not worth trying to get what EDGE you can from Rogers/Telus/Bell.
* Ontario biased *
I would recommend to get an unlocked ATT phone
So after some research, the G2 is a quad band gsm phone, which means it should work on any GSM based carrier. From what I've seen that would be mainly rogers and fido correct? Or are there cheaper alternatives?
Also I looked into the AWS but I'm not sure if my g2 is compatible with AWS. It seems as if tmobile uses both. Does that mean my phone is compatible with GSM and AWS? I'm wondering if you could confirm this Ariel?
Also I will be in the montreal area.
Yes. It will work but the G2 doesn't have the same 3G bands as Rogers. That means you'll only get EDGE which, by personal experience, sucks. I'm not sure about Fido, though.
k, what about an aws service like videotron? That should work as well correct?
Can anyone confirm if these bands will work of AT&T? I found an unlocked HD2 with these bands, and bands for AUS, and need to know if they will allow this HD2 to use the 3G data service of AT&T.
GSM 850/900/1800/1900MHz|HSDPA 900/2100MHz, 850/2100MHz (Australia)
This is what the overview says in the features list:
3G speed
Offers quick and easy connection speeds.
Operates on quad-band GSM/HSDPA wireless networks
For reliable wireless communication.
I don't think so because if I recall ATT needs 850/1900 for 3G.
It does look like it will work on tmobile 3G though.

That would be a good reason to return it then. It's advertised as working on all data networks and has a quad band HSDPA radio in it. If I can't get it to work on AT&T, I will return it for a refund.
Thanks for the reply, by the way.

"working on all data networks" is correct, but not 3G. Any unlocked phone works on all data networks, but not all UMTS/HSPA networks. The quad band aspect of it is because it apparently works in Aussie and Tmobile, but from what I see there not on ATT
Hi,
Forgive me if this has been asked before but i did search and couldn't find anything that i was looking for..
so, I'm planning on buying a verizon LTE tab (4g + wifi) and i was wondering would it be possible to use it on a 3g network? The verizon rep i talked to said that yes this was possible but i'm not sure they knew what they were talking about.
Also, does it need to be unlocked to run on another network or does it come carrier unlocked? if yes, is that currently possible? because i asked verizon and they flat out said no..
Thanks and apologies again if i missed any threads related to these issues.
nevermind, got all the answers i needed
while LTE is backwards compatible with GSM, verizon uses the 700 frequency band which unfortunately is not what i was looking for
Typically 3G and GSM use different radio hardware, or even a different chipset. So a GSM LTE phone/tablet will have specific radio hardware for 2G GSM, 3G GSM and LTE. Verizon's LTE phones and tablet will only have CDMA for 3G and LTE. So, even if Verizon uses GSM frequency for LTE, it will still not operate on GSM networks, only LTE networks.
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.

It's 3G, check Engadget. I'm sure it's 2G as well. And I know of at least one phone that is pentaband UMTS...mine, the Galaxy S II lol

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

Yes, but is it DC-HSPA+? If not, no 42.2Mbps for you!

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?
Edit: it's 700/1700 for LTE and then the normal AT&T bands for WCDMA

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
