I've done the whole diagnosis tweaking (release 6) and pretty much all of the other tweaks I've found in these very helpful threads.
But my download and upload speeds are atrocious. 80-150 kbs mostly. I ALWAYS have a 3g signal. I'm located in Boston and before this I had a Tilt2, which data speeds avg. 2000 - 3500 kbs.
Could it be my sim card? it is like 3-4 years old. Just a thought, because really i have no idea.
I am a novice when it comes to this type of tweaking. Any help would be greatly appreciated.
Thx
The specs indicate that the Focus is only capable of HSPA (HSDPA and HSUPA), not HSPA+.
Michael.
ouch, that hurts....8(
Thanks for the quick reply...much appreciated
But your Focus should still be able to match the speed of your Tilt2 which is HSPA as well (but with HSUPA disabled). The real world experience really depends where you are and how many AT&T customers are on the same tower as you. I routinely get about 100kbps speed (download) on my various 3G smart phones as well here in nation's capital.
On the other hand, a lot of ppl who bought the new '4G' HSPA+ AT&T phones (Inspire 4G and Atrix 4G) are also rarely ever get HSPA+ speed at all. Those so called 4G phones also comes with HSUPA disabled.
So, in the end, it is the same crappy AT&T network that limits your connection speed, really doesn't matter what phone you have. I'll be happy if I can reach the full 3G speed (2 to 3 mbps down, 1mbps up) in next few years. And refuse to play the AT&T '4G' game.
You should get a new sim card considering it is 3-4 years old that will affect connectivity to 3g and hspa network..
Boston network shouldn't be a problem.
Samsung Focus At&t USA
I had the same problem when I had an old SIM card in my att fuze when trying to connect to 3g and hspa speed networks...rule of thumb is buy a new SIM when switching to a new phone....it also depends on what network your on...are you at&t?
Samsung Focus At&t USA
Yes, I am currently on Att network. Which I must say was really reliable and fast, up until the last few months...
And I will get a new sim card after work today or early tomorrow. I will let you know if that helps at all.
Thanks peeps 8)

Samsung Focus unlocked I get 3G+ in EU, if that helps. Seemed pretty fast, but I haven't done a speed test, though.
Usually I unlock my phone as soon as I get it home. With a bunch of unknowns with the Focus, I'm waiting it out right now before I do anything

I got 3G+ icoon with Rogers ROM, but not with AT&T ROM. And there's tool which can enable 3G+ icon, so I think it's just a registry issue.
3g+
I also get 3G+ with a Rogers sim card in my Focus, same card in the BB only 3G.
Is it possible to check whether this is just graphic, or there is a real difference in d/u speeds? I am using AT&T Focus in Europe.
You can check real speed with speediest.net to differentiate whether its gfx only or real network.

I'd love to hear what results you get if you test out the download/upload speeds. Like others have said you can use speedtest.net or there's a pretty good app called Bandwidth that I use.

Hi!
Now I think I may get a few people thinking I am wierd but hey!! I would like to know a bit more about HSPDA. I know it is a new speed access for data. But how do i activate my Ameo to use it and does anyone know where i can get a coverage map to see where i can use it??
HSDPA is activated on W'n'W Plus by default - not sure how you tell on the Ameo - some ROMS display H instead of U/3G but the Ameo doesn't appear to.
On my HTC Advantage on Cingular it dispalys 'H' when I am in a HSPDA coverage area.
yes mine displays H at times
I have been wondering the same thing (i.e how to tell when the Ameo is using HSDPA).
In the UK, I have never seen an "H" displayed with my Ameo on web'n'walk
Like I say, on other phones it depends on the ROM - I have never seen an H on my Ameo and have been getting far faster than 3G speeds!
On T-Mobile UK, wherever there is 3G, there is HSDPA. The T-Mobile ROM does not change between displaying 3G and H - no need becauise 3G = H on T-Mobile UK.
I forget the max T-Mobile speed at present - about 600k I think. If I remember correctly, they are aiming to double that in places by the end of the year.
No need to configure an English Ameo for HSDPA.

i don't think what you say is correct. There are lots of area where you can only get 3G instead of HSDPA with T-mobile. I have DOPOD U1000 but I am using T-mobile Sim Card. It's clear to me that most of the time in London, i will get H display on my phone, but once I moved out to other place, I start seeing 3G signal only. And yes there is a speed difference. And I have also run tests on the HSDPA speed, on average i am getting 1000k (1M), the top speed i ever got is 1200(1.2M).
Could do with your support buddy...

The info comes straight from several sources at T-mobile - all their 3G coverage is also HSDPA. However, I have an Ameo, which only ever shows 3G.

that is certainly wrong, i have seen 3G and HSDPA separately in different location. The speed difference is huge. BTW, you shouldn't listen to mobile operator, most of the time they don't know what are they talking about. Guess what, some of them don't even know there is a 3.5G (HSDPA). (I mention this to them, and they ask me to google it !)
I have a unlocked tmob hd2, using it on ATT.
I get Edge ( as expected ) but that seems to be very slow....( probably this is the speed of edge)
Is there any specific radio version for using with ATT.
Any user experience is appreciated
I am using the tmobile hd2 on ATT and the speed seems fine to me. I am usually on wifi and really dont take notice of it. then again, how can you test the speed to know that you are getting true EDGE network speeds?
Also, I am using a custom ROM [Manila version touch x-treme 2.30.6.30],
with radio version 2.08.50.08_2
Bytheway, is it even possible to change the radio version? I would think that whats on the tmobile phone is specifically for their network.

Funny thing is my unlocked HD2's radio reception and quality is much better running on ATT compared to when I had the T-Mo sim chip in. I must have some really crappy towers around me or ATT just saturates the area or the radio wasn't tested very well on the T-Mo network. Regardless, this puppy runs great on ATT. ATT Edge is better than T-Mo Edge as well. Go figure.
When i checked the speed 3g vs edge on att its huge
download speed 1574 vs 124
Upload speed 331 vs 19
Edge really feels so slow, especially after used to 3g speeds...
Probably get telstra then
Edit to correct the speed no. s

Hmmm, my download speeds on Edge match or slightly exceed your downloads for 3g. My downloads for T-Mo averages less than 100kb. I do get better results not using the ATT proxy though.

Radios aren't assigned to carriers. What works on T-Mobile will work on ATT. If you are on ATT using an unlocked T-Mo HD2, no matter what radio you use, you will not get 3G - different bands.

Do they really have a separate hardware for different bands? I doubt it, would be pretty expensive. If it's a software, I guess we can expect somebody to hack it and enable all HSDPA AT&T bands

It's actually for bands, so yes, there's separate hardware. Carriers do this to help instill customer loyalty and retention, among other things. There simply is no way to "hack it and enable all HSDPA AT&T bands"
SO If I have a TMO HD2 and have AT&T service - If I am a big internet user - I shouldn't bother with this phone? My Fuze will be faster? Or is it worth keeping the HD2 on At&T? I love the phone - the size, the screen, the features - ect... but If it is going to be a slower user experience for data I rather just sell it.

It just depends on 1) how available wifi is as an option for you, and 2) if the EDGE speeds (in your area) are acceptable for when you'd have to be on that (no wifi available). My guess is that they probably won't be, especially if by "internet use" you include a lot of webpages, and/or streaming of any kind.
HSDPA? I always have an H on my phone - can the TMO HD2 do HSDPA on AT&T? If so is that different? I know I am a noob when it comes to bands.

No, HSDPA is just a higher-speed 3G spec...it uses the same band ranges as regular 3G, so the same incompatibility still exists between AT&T and Tmo
Going back to the original question.
Is there any users on ATT who find a particular radio more useful than other...
WIth regards to edge reception
Thanks
I used 2.06 2.07, 2.08 with no difference on edge speed, I am in Dallas. However, in some areas I can get 3G, I thought HD2 was not compatible with US 3G frequencies, go figure.

That is interesting.
I just unlocked my HD2 but have yet to stick my sim in it - still on my FUZE... Debating on weather to sell it or use it.
I am running TMOUS unlocked HD2 on ATT.
I moved from original TILT and to me EDGE seems way better than 3G on my old TILT. I think it do to the processor speed probably but for me the results are still great.
I can only imagine how TELSTRA version would run on ATT !!!
Anybody know how actually measure the connection speed of my phone?

Visit that site from your phone's browsers for a speed test. You'll probably get slightly different results using IE vs Opera, so try it several times to be confident in your results.
Avoid mobilespeedtest.com if you come across that site...their results are inconsistent and unreliable.
After reading of a new Mytouch HD product that is coming for T-Mobile Im pretty impressed with specs but very turned off by the looks.
So that makes me wonder does vibrant have the technology to run on T-mobile's 4G network with simple software updates?
Reason I am asking this is because I know The iphone 4G will be able to run on 4G network as soon as AT&T launch their 4G service.
Thanks for any knowledge in advance
.... Google is your best friend, its not 4g it's hspa+ on order to take advantage of that speed you ned the physical hardware in the phone which only the g2 had right now, in regards to the iphone 4, I've never heard anything about att launching any 4g network, I also work for att, the iphone doesn't have any hardware that support any faster speeds as far as I know

iPhone can handle ATT's new "Faster 3G", but they don't have 4G. My understanding is the Vibrant can do HSPa, but not HSPa+? I don't know the difference but that's what i understand. 2G, 3G and HSPa.
4G is just a marketing terms for the masses. After you look at this link...
http://shop.sprint.com/en/stores/popups/4G_coverage_popup.shtml
You should realize that the Vibrant is already capable of reaching the "average" speeds listed here (in areas with proper coverage). Wait...how is that possible?! It's not a 4G phone. Who cares!!! T-Mobile's network and phones already meet or exceed the speeds Sprint is advertising here. T-Mobile is way ahead of the curve here but they're not marketing the hell out of it. FYI, the average website (ATM) may have trouble maintaining a consistent throughput of 5-6 Mbps anyway. Even if you can go faster, does it really matter when the other side can't (yet)?

Apple hasn't announced a 4G Iphone, so (by definition) you really don't know what you're talking about.

You should ask yourself why you care about 4G. I doubt you'll notice much of a decrease in load times, and the carriers are probably going to charge out the yin-yang for the enhanced features they will be able to offer to everyone with 4G.
AT&T and Verizon are going to limited data (AT&T already has). You should really look past all the marketing and hype. All the carriers are guilty of confusing the public to serve their interests.
All T-Mobile phones will benefit from HSPA+ as it's backward compatible. However, the theoretical maximum throughput on the Vibrant (or any legacy phone) that doesn't have the HSPA+ antenna built in caps out around 7Mbs as I recall. The G2 which is built to run HSPA+ has a theoretical througput around 15-20 I believe.
Seriously though, even 7Mbs is pretty stupid fast for a cell phone.

Check the data icon top center - should be two arrows (up/down) and 'G','E', or '3G' to indicate tech. GPRS would be my guess for 50k... EDGE should reach around 200kbps. (I've maxed at about 1.8 mbps 3g in Charlotte, about 210k edge nearer home, and about 12mpbs wifi - same locations as that last my netbook gets 40-70mpbs though.
Check 'settings'->'wireless and network'->'mobile networks' and make sure '2g only' is unchecked. If so I'd suspect a hardware problem. (double-check that 3g is available where you're testing, of course)

theoretical caps. HSDPA 7.2Mbps, T-mobile's variety of HSPA+ 21Mbps according to a T-mobile press release, Wi-fi G 54Mbps.
real word numbers HSDPA 1-5Mbps in good coverage depending on network traffic, HDPA+ on a vibrant 3-7 Mbps again depending on network traffic, Wi-fi... depends on your home internet connection speed.
Some people seem to misunderstand whether or not a non HSPA+ phone (such as ours) can benefit from HSPA+. It indeed can, but not in a straightforward way. In order for T-Mobile to support HSPA+ in a given market they must make reasonable upgrades to their networks backhaul capacity to support it. And these backhaul upgrades will become more important as T-Mobile actually begins selling HSPA+ devices.
One of the most important factors often overlooked with any network is it's backhaul capacity. Bottlenecks in familiar networks can easily make themselves apparent. Take for example the traditional DSL and Cable networks most of us use for wired internet service.
While you may pay for a given advertised speed, whether or not you actually see those speeds has less to do with the connection type and more oftentimes to do with how it has been implemented. In the case of DSL for instance, whether or not you can experience your advertised speed reliably depends on how many other customers are routed through the same DSLAM, *AND* how good the backhaul connection from the DSLAM is to your providers internal network. The same thing occurs with Cable and how many customers are aggregated into a given areas HFC. Bottlenecks within cable and dsl infrastructures occur at different points (because they're architecturally different), but once your outside those infrastructures they both share the potential for having backhaul bottlenecks.
In my area cable is way the fastest connection option, and though I do not pay for the highest speed tier here (15/2, instead of the 10/1 I have), when 10/1 was the fastest tier I'd rarely actually see those speeds. Now I see those speeds reliably. Why? Well there are many factors that effect a network topology, but it's clear that in order to reasonably support 15/2, my cable provider had to make sure it's backhaul could actually handle the load, so it was likely updated to accommodate this.
Hope this clarifies things a bit.
I've been noticing on liberated aria roms that instead of 3G, it is reporting data as being HSPA. I was curious as to the authenticity of this.

HSPA is the same as 3G on AT&T. HSPA is the technology AT&T uses for their 3G, and for some reason on the Froyo ROMs, it shows up with an H.
People have told me that its the same but when I speedtest my 3g and hspa the 3g is a little less for me. Like one time I had 3.87mb on 3g and when I flashed the hspa Rom it came up with 4mb.
I always throught the OEM rom had 3G (3.6mbit), while CM6 and perhaps the modified liberated roms had unlocked 3.5G (7.2mbit).
NO^^^ the speeds you experience on both roms are the exact same... who ever created the rom just decided to replace the 3G symbol with an H!

Yeah I dunno if I'd necessarily believe that. I notice when I do speedtests the HSPA is a bit faster, or at least thats what the speedtest app says. You notice it more on uploads, than downloads.
I believe the correct abbreviation is "HSDPA", or no?

The difference is that the ROMs with 'H' has HSUPA (faster uploads) turned on and the stock AT&T with '3G' does not. Category 5 HSUPA to be exact. http://en.wikipedia.org/wiki/High-Speed_Uplink_Packet_Access

The technology is HSPA, HSDPA is the download speed, HSUPA is the upload speed, that is why you see the 2 different mnemonics used interchangeably.

This at least goes along with what I've noticed.

I always throught the OEM rom had 3G (3.6mbit), while CM6 and perhaps the modified liberated roms had unlocked 3.5G (7.2mbit).

I always assumed the same thing(never did any research to actually confirm). But from a practical point of view, I never noticed a significant speed increase when switching from stock to CM6.
You are all wrong. Att roms are compiled to use the 3g icon. When compiling roms/or using overseas roms its usually compiled to use the HSDPA icon. Its a known fact. HSPA and HSDPA are two totally different things. Proof to back it up? Its a build flag when compiling roms. You can also.check in settings->phone status. They both say hsdpa. So both roms get the exact same speed. Just use different icons. The speed changes you may notice are just placebo. Nothing more, nothing less.
Yeah I have had no speed increase from 3g to h...both pretty much same using 3g speed tester

HSPA is the same as 3G on AT&T. HSPA is the technology AT&T uses for their 3G, and for some reason on the Froyo ROMs, it shows up with an H.

No it's not. HSPA is not the same as 3g - it is faster, and yes, ATT has had HSPA for quite a while.

Right - case in point - I had another unlocked phone (SE K850i) in late 2008, which typically read '3G' throughout the SF Bay Area, but I noticed it turned to 'H' when I traveled to Seattle at the time.
Tethered to a laptop, I got (roughly, from memory)
H 1.5MB down 700K up
3G 1.1MB down 144K up
Sometime in spring of 2009 ATT upgraded their network in the SF Bay area to HSPDA from the former UMTS (3G) network. The phone then read H thereafter and got similar speeds to what I'd seen on my trip in Seattle.
So, the older 3G network was UMTS, not HSPA. It's possible ATT still has some UMTS / 3G networks laying around elsewhere in the country, but I haven't seen '3G' on any of my phones that make the distinction recently in the SF Bay area, they're either on Edge or HSPA these days.
What's really funny is that, with all the current 4G marketing blitz, ATT probably missed out calling their HSPA network something better than 3G very early on, but instead just dumbed down their phones to all read 3G...perhaps to hide the extra time it took them to roll out HSPA...perhaps to avoid questions from thousands of people that would call in wondering why their phones didn't say 3G.
Anyhow right - Edge (2.5G) < UMTS (3G) < HSPA (3.5G)
Hey guys,
So I'm in the market to possibly replace my Sony Xperia Z3 and I'm intrigued by the sheer awesomeness that is the Note. I'm wondering if I ordered the phone from china, would I be able to use it with an AT&T Sim card and have cellular access? I don't need FULL LTE speeds, though I'd like to have close to that.Sorry for the newb question! I couldn't find an answer to this anywhere.
Cheers,
Bump! Still need this information. Thanks!
You will get EDGE ans GPRS... I'm on Rogers in Canada and I think it will be the same for AT&T....
On the flip side you get great battery life...

I have tested using my AT&T SIM card in the USA. I have the export model which says fdd-lte/tdd-lte/wcdma/gsm on the box label. I get H, or H+ next to Mobile strength to pop up on the top header which I believe is GPRS. It also says AT&T 3G on the top header, so I don't believe you can get LTE in the States. As stated, battery life is excellent. I'm still on V5. Struggling to upgrade to V6. There seem to be many links and different versions of V6 for the 4G. I have tried them all, but I get a big X and a stop message in Chinese, so I'm not sure what any of it means. It just reboots to V5. Will keep exploring.

What type of download speeds are you getting on the Note with AT&T non-LTE?
I am looking at purchasing the Note Pro and trying to get a comparison.
Thanks.

Sorry, just noticed your post. It varies but on my last test I got a Ping of 21 ms, Download of 6Mbps (it seemed to slow down as the test proceeded) and Upload of 6.4 Mbps. Still running on 3G. When I get H+ the download speed seems to go faster, but the upload much slower. Again speeds seem to vary, depending on the signal.
I tried to modify the phone to get AT&T LTE bands, but no go.
I am using Redmi note 4(bought in India). I have H2o sim, which use AT&T network. I am getting LTE here in Texas. and download speed 3.5 MBps and 0.74 Upload. not bad for my usage.
