Post your speed USA EDGE - Desire General

Is anyone using the A8181 on USA EDGE network. Would it be possible to post your download and upload speeds? I have one coming in the mail and I haven't decided what to do with it.
I am thinking of selling it to get a Nexus One, which I sold to get a Slide.
is 900kbs/sec out of the question for edge? 1mb?

Yes, 900 kb/sec is out of the question for edge.
EDGE (Enhanced Data rates for GSM Evolution) or EGPRS provides data transfer rates significantly faster than GPRS or HSCSD. EDGE increases the speed of each timeslot to 48 kbps and allows the use of up to 8 timeslots, giving a maximum data transfer rate of 384 kbps.

Remember, that is max possible speed. The real-life speed is much lower.

Thank you. I don't think I can live with 328 max. My slide is getting 3000+, on the new updates. That is in the peak in city though, in my neighborhood I average 1200 or so. Looks like I will never get to know the Desire.

You didn't understand what I quoted. That is the max speed of EDGE technology, it has nothing to do with Desire, Slide, or whatever. That is the technology capacity.
Are you sure Slide is on EDGE and not on 3G or HSDPA?

My mistake, I understood. I forgot to tell you my service provider, sorry. I have a USA t-mobile and I pay for 3G service.
If I use the A8181 in the USA it will only get EDGE, SO FOR ME**key words** it will not go faster than the EDGE technology will allow it.
On my slide I am able to pick up USA 3g and hsdpa+ as you can tell from the speeds I listed
My low end speeds are around 700 and that would have been enough hypothetically. But I am an idiot, because I should just disable my 3G and run an edge test from my own neighborhood.
Thank you again though, you gave me EXACTLY the answer i was looking for, and quickly.

I wish man. The A8183 will work on USA ATT 3G. I am stuck with T-mobile.
If I had ATT I would look into the A8183 for sure.

I have a A8183 that I bought in London and use it here in the US on AT&T...no 3G only EDGE.
3G bands on this phone are limited to 900/2100, AT&T uses 850 and 1900.

A8183 is the Aussie model, not the Euro model, which is A8181.
A8183 = 850/1900mhz 3G
A8181 = 900/2100mhz 3G

Actually if you look online the A8183 uses 850/2100 bands for the Data.

Oops, you are correct.

A8183 on US 3G
Is AT&T the only US 3G network that the A8183 will work on ?
I ask because I am trying to find a phone (ideally a Desire) that will work on UK 3G and US 3G.
The A8183 does 850/2100 which I believe will let me do this ?
thanks

Alternatively, you could get a Nexus One as this will work on TMo in the US, and on UK networks.

T-Mobile US rolled out 3G - anyone able to get it on diamond?

...any luck? any radio updates for this?
I am a US TMobile subscriber, and here's what I know:
TMobile has only released 3G in a handful of cities, including NY, Vegas, and Houston (or maybe it was Austin).
Tmobile US runs on UMTS 1700/2100.
The Euro version of the Diamond runs on UMTS 900/2100. However, this 2100 band is supposedly "different" and will not run on TMobile US.
And the US version of the Diamond runs on UMTS 850/1900, which is what AT&T uses, and that won't work on the TMobile 3G network.
Long story short: no you won't get 3G with TMobile.
I have gotten 3g to work on tmobile but not in nyc. It was actually in central nj by philly. I took a few screenshots but not uploaded them yet. i got radio 1.25.05.
Great, could you please post the screenshots as well as your ROM version?
Dimond supposedly supports 1700 so not all is lost I think.

I just got my "US version" and it's WCDMA 850/1900...
And I can see "G" icon coming up in "some" place.
But most of time, I only can get "E"....
I am sure my city already got T-mobile 3G service,
Because my friend who got a T-Mobile NOKIA 5610 ( 850/2100 ? )
His phone can always get a "G" coming up, and we tested the up/down speed
it's 153 / 42 kbps something.
I really want to know how to make mine working.
G is actually bad, it means GPRS not even EDGE (E) and the speed you posted is way to low for the 3G which should be a few MBPS actually.

Victor, the "G" is GPRS, not 3G. "E" is EDGE, which is a bit faster than GPRS.

I have a htc diamond 3700 DIA100.
Same as above post, I get G sporadic around philly, but it says 3G not GPRS in the info.
I think that's just the name of the data network. Your actual data connection would have a 3G icon if it were 3G.
my diamond is from hong kong.

I don't think the WCDMA work on 3G networks. Different technology. I also don't think the regular US GSM phone will work on the tmobile network. Different wireless bands from AT&T...
I don't think any of the Diamond (US/Euro version) will work with US T-Mobile 3G, only PDA phone that I am aware of is the SonyEricsson X1 with 1700/2100 band.

WCDMA is the air interface used by UMTS & HSDPA so it is what we need/use for 3G on AT&T (and T-Mobile - just on a different frequency.)
On all WM phones I've owned I've never seen the choise of choosing UMTS or HSDPA in phone settings. You always get either AUTO, GSM (straight GSM or EDGE) or WCDMA (UMTS or HSDPA). And, when choosing WCDMA I will get HSDPA (as long as I'm in an area with it, of course.)

US Touch Pro 2 Unlocked

Anyone know if they will be releasing an unlocked version for the US carriers? I would get the European version myself, as 3g isn't a big deal for me, but what gives me concern is the Wall charger doesn't include a US plug. Im sure this is a small deal considering i could proly just buy a standard HTC charger, but im just curious if they will be having an unlocked that will both include the US charger, and work on US 3g networks.
no word yet hua?
Why do you think the European model won't work on U.S. 3G networks?
European 3G I believe works on the 1900 MHz band (supported by the Touch Pro 2). U.S. 3G operates on the 850 MHz band (also supported by the Touch Pro 2). By technical standards, this should work fine in the U.S. on the 3G band.
As far as the charger goes, yes, that is a concern. But I don't doubt that somewhere in your house you've got a miniUSB charger lying around. If not, your local Wal-Mart/Target/Radio-Shack/Best Buy will have a million of them.

I have been on a number of blogs for the TP2 and they are seem to be in agreement that the European TP2 will only work over the EDGE network in US...

Here is a good story on MSNBC.com on the various 3G standards. It is dated last Sept. but it is still good.

uk/europe model will only work on edge in US. devicewire have done a detailed review on a europe model and could only get edge. to get 3g will need to wait for official model for that region.

Actually you have it awry. European 3G runs on 2100mhz not 1900. U.S 3G runs on 850/1900mhz.
If you go to HTC's site, the TP2 Euro model will do GSM/GPRS/EDGE on 1900mhz. SO if O.P imports a Euro version, he could use it on EDGE or he could just wait for the AT&T version. T-mobile USA's 3G runs on 1700mhz though.
T-mobile USA's 3G requires both 1700mhz and 2100mhz. Suppose to be hear around July 22nd...

Standard mini usb cables, yes and i also am aware i can also just charge the thing using the included USB cable. What im asking about is the WALL charger. If HTC uses thier standard USB-mini cable that is on a good chunk of their devices, including the HD/ Tilt/Diamond ect.. im sure finding a US charger wont be that hard.
Also, i was asking about an Unlocked US version, i do not intend to get one though the carrier as i dont want a modified version that they lock down. Nor do i care to wait till the fall when AT&T gets off their duffs to finally release it.
In any event, im just keeping my ear open and seeing what the grapevine heard about it.
Sorry guys. My bad.
I was confusing the specifications thinking that HTC would at least be smart enough to include full support for all markets. I was reading the Quad-Band GSM as support for HSPA/3G bands. I was totally bypassing the HSPA/WCDMA dual-band specification.
Chalk it up to a mix of wishful thinking and childish excitement. That does, however, kick the crap out of my week. Only HTC can bring me down this hard.
Well, I guess ATT got approved for theirs. Now the only question remains is, will their be an unlocked US version that supports 3g? or will we have to get the European version?
I'm in Taiwan for Computex and am so tempted to buy a touch pro 2 here. I would wait for the AT&T version but after seeing they changed the keyboard I want the HTC model. Only reason I haven't picked one up yet is because it only gets edge in the US on AT&T.
Does anyone know if the hardware cannot physically work on at&t's 3g bands or do we just have to wait for the at&t version to come out so the radio can be copied over or something. Thanks!

The hardware physically cannot handle it. The Euro/Asian model only supports 3G on the European and Asian bands which are completely different frequencies from the ones used in the U.S. It's definitely not just a matter of software.
And I think we all need to be clear that no one has any idea what the AT&T keyboard will actually look like. The promotional material we have all seen and discussed ad nauseum is a slap-together of the HTC mockup with AT&T's promotional verbage. Even the promotional bullet points list that the "HTC Fortress" has a 5 row keyboard while the mockup picture shows a 4 row keyboard. That picture, at this point, means pretty much nothing at all.
I see, Ill hold off then. Its kinda hard to justify ~$800 on a phone here anyways that doesn't have a warranty in the states. Thanks for the help!

the carrier phones usually come with some sort of branding (software: e.g. sprint tv application / hardware: different battery cover, different keyboard layout and so on)

This has already been answered before.
The Rhodium they are selling only supports 900 MHz and 2100 MHz for 3G/HSPA. AT&T requires either 850 MHz or 1900 MHz. So the clear answer is No, it will not work with AT&T 3G.
To answer the obvious question somebody else will ask next, the 2100 MHz band is used in T-Mobile's 3G network, however TMo's network requires that the phone support both 1700MHz AND 2100MHz for the up and down streams, so this phone will not function with the US T-Mobile 3G Network either.
The phone WILL function for making calls or data connections over the Edge bands (GSM/GPRS/EDGE) for both US providers...So the phone is certainly functional, but it won't make high speed data connections in the United States.
If anything I've written is incorrect, please mock me

Stupid Question - Tmobile TP2 radio on ATT 3G

I'm actually a little embarrassed to even have to ask this question, I'm also pretty sure I know the answer but better safe than sorry. Can anyone confirm that the Tmobile version of the TP2 is able to access the ATT 3G network? I'm 99% sure it will but that weird Tmob band makes me nervous, any input would be appreciated.
No, it will not. However the ATT version shouldn't be too far behind the Tmo launch so don't worry too much
no offense but what is the basis for your statement, the Tmob version will have
850/900/1700/1800/1900/2100 bands which are basically the ATT bands plus 1700, why would the Wing II not work on the ATT network?

Please show me where you found this data? Tmobile USA 3g network doesn't use the 1900 band for 3g; they use the 1700 band which is why Tmobile has to have devices specifically made for their network and why the Tmobile USA version won't work on ATT USA.
Again to clarify:
Tmobile USA = 1700/2100 for upload/download for its 3G
ATT = 850/1900 for upload/download for its 3G
Now Tmobile USA does use the 1900mhz frequency but that its GSM frequency it is not related to the 3g frequency. Confusing i know, but you asked.
One of the images advertising it does state all those bands, but does not differentiate which are for gsm and which for 3G (which can be misleading and confusing, ergo the clarification by jim_0068 ^). Though if they share the 2100 I have no idea whether you can get limited functionality or if you HAVE to have both of them. *shrugs*

actually this is not entirely true either,
AT&T is using 850 and 1900 Mhz for their 3G network,
it was revealed recently that they are pushing the 3G network to the higher frequency (850) and plan to have the 3G completely on 850 by 2010.
if AT&T is using 2100, we would've been able to use the european HTC devices which has the 2100 band.

As far as I'm aware:
GSM: 850/900/1800/1900
UMTS:1700/2100
And therein lies the problem... While it supports all the bands that would be required, only a small subset actually apply to a 3G connection/signal...
Minimally, that would be the specs for it to work on T-Mobile, and quad-band GSM is just standard on 99% of phones these days...

You're correct and i edited my post it is 850/1900 for ATT US 3G
I gaurantee you that the T-Mobile Touch Pro2 will not work on ATT's 3G Network At All... the frequencies for ATT will only support the 2G Network and therefore only phone calls and text messaging will work.
let's not go that far, let's not forget gprs (same speed as dial-up) and more importantly EDGE (for some that's more than enough).
when I go into the phone settings -- band I have these options on the Tmobile TP2:
GSM (900+1800)+UMTS(900+2100)
GSM (1900+850)+UMTS(1900+850)
UMTS(2100+800)

It should also work worldwide too.

I think those numbers are for software only, in fact you probably don't have the hardware to support the frequencies of the wrong carrier.
seems that 800mhz is for Japan
and it doesn't allow for all of the North American bands (it's missing the 1700 one).
Could be just a software thing without hardware support, though that might be a tad odd, any way to check if it is?

It's very likely that the numbers you are seeing are actually all of the frequencies that are "summed up" and therefore the TP2 for T-mobile does not have the actual hardware.

hmmm why is there 800 MHz?
Obviously this is some bull**** because it supports all of the 3G frequencies of worldwide carriers and american carriers.
I wouldn't trust this guy, he has 4 posts and he's obviously posting rumors.

Those options have been around with the custom ROMs, I have that too on my Fuze, if your hardware doesn't support it then it'll just be an eye candy.
Bottom line is this, if you want to utilize AT&T's 3G, then you'll need to wait for AT&T's Fortress because you need the 850 and 1900 band (UMTS band II). If you want to use T-mobile's 3G you still need a TP2 that has the 1700 and 2100 band (UMTS band IV), and no you cannot use european TP2 to access US T-mobile's 3G band because european's (and asia's) 3G utilizes UMTS band I, they are on a slightly different frequencies even though they are categorized both on 2100Mhz.

Using my Desire in the US?

Hi.
I have a UK Desire (Vodafone) and am soon going to the States (California) for a while. I know I won't be able to use 3G, but I'm assuming that I will still have no problems with calls and data, albeit the data will be a little slow. Is that correct?
Thanks, in advance.
correct. (the message is too short so I typed this extra sentence so I cuold pst a reply )
Actually, not completely correct. If you use the T-Mobile US network, you can use 3G.

How is that? I have an A8181 and not sure what settings I need to use 3g.

Actually it's completely correct. The Desire doesn't support the necessary bands for US T-Mobile.

I will be tomorrow in the US ( Boston area ) let's see what will happen.
No matter how be aware that the data comm's are more expensive then phone calls.

T-Mobile US runs 2100 for 3G doesn't it?

It uses a pair of frequencies - 1700mhz and 2100mhz, otherwise known as AWS Band IV.
Crucially though, a phone requires both frequencies to operate on T-Mobile US's 3G service because it uses 2100 MHz to transmit and 1700 MHz to receive.
Since the Desire doesn't support the 1700mhz band, it can't work on T-Mobile US's 3G network and is restricted to EDGE.

To be honest, the first thing I would be doing is turning roaming data off, unless you are made of money that is!
I travel weekly to the US, and have a T-Mob payg sim, that works no problem for me, but 3g is another story as stated earlier, the charges for data in the us are high, but you still have wifi, so just find a starbucks, mcdonalds, etc to connect, and most hotels have free wifi, download apps that search for free wifi around you.

There's a setting on the Desire to prevent Data from working when it's Roaming but in general agreed.
GPRS/Edge are so painfully slow I wouldn't bother, even if it was cheap.

Does this apply to HSDPA too?
HSDPA is 3G really, so yes.
Thank you.
