I'm told that it should be impossible to get 3g connectivity on a G1 with an ATT sim, something about the antenna, but lately thats exactly what i've been getting.
Specifically, near powell st (in the bart station almost all the time), near montgomery st bart station, and down around west portal, i'm getting 3g speeds.
Anyone in SF with a g1 and an ATT sim want to try and replicate what i'm seeing?
Weird. The only explanation is you're getting some 2100Mhz (Band I) UMTS coverage (the iPhone 3G can also connect on 2100Mhz, explaining why AT&T would have it). I had no idea AT&T had any 2100Mhz UMTS bandwidth allocation though.

Do you have roaming enabled?
I would hazard a guess that you're probably roaming onto T-Mobiles 3G network, but that rather assumes it covers the area in question. It's either that, or AT&T are trialing something there.

That is what I thought too, initially. However, what benefit would AT&T have in signing 3G roaming agreements with T-Mobile, considering AT&T sells no 1700Mhz equipment?
No idea, but it is possible.
I suggest one possible approach would be to use CellFinder to identify which cellular towers are providing this 3G signal on AT&T, and then see if you can find out what services are provided from this tower and by which carriers.
I've just noticed though that CellFinder doesn't work anymore on Haykuros 5.0.1G!

I have the X1i
Overall very pleased with the phone, but able only to use GSM/EDGE because my provider works over 850MHz
I´d like to get the X1A too
Best Buy and Sony Style are taking pre-orders for january, not in stock...
Where can I buy one ??
Are they (X1A) already -really- "released" ??
Not already available ???
...eBay? A few auctions are for the X1a version. Make sure you ask the seller which version it is!

This question has been asked and asked on this sub-forum, I know ... but:
1) which region are you in, please ? I don't mean actual location, suburb etc but rather city or country area ?
2) if city, have you yet tested 3G connection in a country area?
3) if country, have you yet tested 3G connection in a city area ?
The reason behind these questions is to ascertain whether the A version of the device can connect to both UMTS850Mhz and 2100Mhz
im from san diego-city area and i get the h instead of the 3g. they are the same but i think because its unbranded, it shows the h instead of the 3g.
im in florida right now and i still get the h.
You get the H because it is really HSPA. I have actually on occasion seen the 3G icon on my X1a.

when you mean 3g cells, you are talking phones? i have two phones, the x1a (unlocked/unbranded) and another cell thats is 3g capable (at&t branded). the x1a shows H, and the other one 3g. i have not seen 3g icon on my x1a and so i thought 3g was only an at&t thing. the only thing that i dont know, is what 3g band my at&t phone supports (850, 2100 or both)
talking towers. although the phones themselves will be causing some confusion.
a HSDPA cell tower will be able to take traffic for Voice or Data on GPRS, 3G or HSDPA depending on your phone. If the phone can't handle HSDPA you'll only see 3G whilst a phone which can will have H
However if you are on a 3G cell tower, it will only be able to do Vocie, GPRS and 3G, so both phones will see 3G

thanks for the clarification.
One correction. You see H is you have both HSDPA and HSUPA. If you see 3G, you most likely do have HSDPA, but just not HSUPA. Most carriers rolled out HSDPA with UMTS and are adding HSUPA after.
3G = UMTS
3.5G = HSPA (HSDPA + HSUPA)
ummm HSPA is still 3G.
the only thing special about 3.5G marketing is that they mean faster speed support like 7 Mbps instead of just 3 Mbps. The HSPA specification can go up to 14 Mbps.

Good question.
My carrier/provider works ONLY over 850MHz: both GSM and UMTS
With my european SE X1 I am getting ONLY GSM/EDGE signal
I have tested 3G with 850MHz phones in my city and I have pick strong 3G signal (not to mention FASST internet ), but again: with the X1i I can't get UMTS service...
i got my x1a from sonystyle.com when it was first released in November.
I have a GSM Touch Diamond and there's no way to use the US 3G even if you have a 3G sim, we discussed it in the Diamond forum and people said it's just not possible. Is this the case with the Blackstone or are you able to use 3G in the US?
if you use a 3 sim you can get service if 3 got a roaming agreement with an usa isp
if the usa isp don't use 3g services on the hz's the rest of the world use you can only get
2g or 2.5g (edge) service
the Telstra Touch HD version (Blackstone - T8285) uses at&t's 850 3G band. it works quite well in the US as long as one is in an area that uses more 850 3G towers vs. 1900 3G towers.

it's 3G from at&t, period. as i mentioned in my post, the Telstra HD is limited to using at&t's 850 3G band. at&t uses both 850/1900 to deliver 3G. if you're in an area that uses only/more 1900 3G towers then you may not have 3G access. i believe Phoenix, AZ is an example. can't comment on the speed with an at&t phone because i don't own one. the pic below is an example of the speed i get with my Telstra HD on at&t.

If there's 850 towers but more 1900 towers then the 3G just won't work at all? It won't just connect to the 850 ones?

i can't say if it won't work at all. for example, if there are 100 towers and 95 are 1900 and 5 are 850 and, you live near an 850 tower, (theoretically) you should get 3G access. using your example, i would say you'd be connected to Edge more often than 3G.

Would you not be able to go into the phone's settings and disable the 1900 band or something? I have a Diamond on AT&T now and it's between upgrading to an HD or waiting another month and signing up with Sprint for the Touch Pro 2 (or Palm Pre now) and then just looking like an idiot carrying 2 phones around.

why would you want to disable the UMTS 1900 3G band? if there are no 850 3G towers, you won't get 3G service you'll get EDGE instead. my phone options are set to Auto for GSM and UMTS and if there are no 850 3G towers it switches to EDGE. simple as that, not a big deal for me (and not implying that it is to you). you can change the GSM/UMTS settings to seek/use only 850/1900 3G towers, but in my experience, if the HD doesn't find an 850 3G tower, i won't have a phone signal, period. if you're in the US and want a HD with 3G capabilities, you get the Telstra Touch HD and accept the fact that having only one US 3G band (e.g., 850 3G) will limit 3G access in some areas.

If there are 850 towers but just not as many as 1900 towers, you could disable 1900 so it only connects to the 850 towers and then you'd have 3G, right? That's what I was saying. I have EDGE on the Diamond but it's so slow it makes me not want to use it most of the time.

uh, no it doesn't work like that. the phone is going to lock onto the strongest signal possible. if it sees a stronger 1900 signal, that's what the phone will use. if you (could) disable the 1900 band and you're in an area with 1900 towers, you would not have ANY signal at all, no phone, no data. based on your level of concern, wait for the at&t TP2 (or whatever it's called); then you'll have no worries about 3G access.
Thanks for all the help, I just ordered the T8285 so I'll let you know how it is. Will I be able to use all my Diamond accessories with the HD (extra batteries, chargers, etc.)?

chargers yes, batteries no. The Telstra ROM that comes with your device will have its internet connection settings locked to Telstra (which we can't obviously use in the US). this means you won't be able to access the internet from your phone until you add at&t's connection settings. i never researched methods to add at&t's connection settings so i don't know if they exist. i flashed HardSPL to my device so i could install a custom ROM. i suggest you click the link in my signature and learn about flashing new ROMS. hope you enjoy your device!

Hi guys,
I just arrive US and got an AT&T sim, I use the same HTC Magic (32A) I used to use in Taiwan but I got no 3G reception
I'm quite sure the 32A magic can operate on AT&T's 3G Mobile Network since it has:
HSDPA/WCDMA: 900/2100MHz
Quad-band GSM/GPRS/EDGE: 850/900/1800/1900MHz
Anyone know why?
I got no Data Plane with my SIM, I'm using a "Nation 1440" family plan.
I got the correct APN set on my phone (though it has no relation with 3G reception)
I'm now using New Radio (6.35.10.18), 1.76.2007 SPL, ROM is Smoki 0.7.6.
The RF Signal Tracker said my Network Type is "EDGE"
I also checked with ATT and they said I got excellent 3G reception in my neighborhood.
And I'm sure I didn't set the phone to work in 2G network only.
This set up works perfectly in Taiwan, so I got no idea what's happening?

I'm no rocket scientist but I reckon that you got no 3G because you don't have the Data Plan... I would recommend adding the Data Plan, then testing out the reception, and seeing if you get 3G coverage. I don't think there is a fee for canceling Data if it turns out that you still get no 3G, at-least not with T-Mobile and AT&T that I know of. I've added and removed Data Plans a few times without many consequences.

That's what I thought in the first place, so I called the customer service and they told me that reception has nothing to do with Data Plane.
Which still make sense to me because from my knowledge, the registration of 3G/2G network is not that essentially related to Data Plane since UMTS / GSM is just a RF technology, normal voice service can also operate on a 3G (to be more precise, the UMTS) network.
But I'm not that familiar the US carrier's policy, so there's still the possibility that a SIM with no data plan is prohibit from registering to a 3G network.
I'll try to find a SIM with Data Plane and put it in my Magic, see how it works...
(My relative happened to be using iPhone 3GS with data plane)

That would be the best bet. Experiment with different sim cards to rule out a problem with the device itself. My opinion would be to take it to an AT&T dealer to quickly cycle through sim cards, if they have any with Data on hand.

AT&T uses HSDPA/WCDMA 850/1900MHz for 3G, so you won't be able to get it on that phone. T-Mobile uses 1700/2100 so you might be able to get it with them. Call and see what frequencies the towers in your area use.
Good luck.

Yeah, I google for a while this afternoon and found that too...
The problem is I do have 850MHz & 1900MHz but thay ONLY operate on GSM, not WCDMA.
T-Mobile uses 1700MHz for down-stream (or up-stream? I forgot). I only have 2100MHz so I suppose I'll have no luck with T-Mo as well.
I guess I'll do without 3G for a while, until I have more budget to get a new Android phone that do operate on ATT's 3G network
Ps. I cross tested my SIM using my relative's iPhone 3G, sure enough, my SIM has 3G reception without question.
Thanks for help from all of u.
Just curious if anyone is using the MT4G on AT&T and how well that's working? I know we can unlock it for use with any carrier but wanted some feedback before I spend the money to get my gf (now using iphone 3gs) an MT4G to use on AT&T.
I already know that 4G won't work. I got her a Captivate for Christmas but she really likes Sense and AT&T's phones are so locked down it's stupid. Can't use custom ringtones, can't sideload apps, etc.
Can anyone help out?
So I'm doing some research and it looks like there's minial wcdma overlap which means spotty 3g coverage? Is that right? I really don't know how to interpret what I'm seeing though so I would be really appreciative for the input of someone more informed than I.

3G won't work either. My question is why on earth would you want to take a MT4G over to the [IMO] worst network of all time?
Only bands 1& 4 right?
Although the captivate supports 2100, at&t only operates 850 & 1900 in the us. Some phones have 2100 for global roaming because that's what most others use.
While at&t does have a larger footprint, I just paid them $180 to get out of my contract and I'm much happier with tmobile. Texts actually send and web pages actually load.
Sent from my HTC Glacier using XDA App
It works just fine, just slower, obviously.
And yes, it is 3G.
Let me be super clear about this... 3G WILL NOT WORK on AT&T. The MT4G just doesn't have the right radio. However, the Vibrant (surprisingly) does have the 850 band on its 3G radio, and does sort of work for AT&T.
If you want an Android phone on AT&T, I recommend buying something unlocked from Canada. Rogers and Bell both share AT&T's 3G bands (850 & 1900), and have a better selection than AT&T itself.
Really great comments here. She's got a year left on her contract, that's why. She's gonna find out her termination fee tomorrow cuz she loves my mt4g, lol.
I always knew that an N1 is definitely her best bet but can't find one used and have an mt4g in the works for $260.
We're talking slightly different things here as well. HSPDA on ATT won't work.
However, "EDGE" describes a family of service classes, not a single speed. Depending on your location and the service speeds there, EDGE may in fact be qualified to be called 3G according to the ITU (the international body that certifies this nomenclature).
As the radio in this phone most certainly does support EDGE, whether or not you can get 3G speeds on AT&T will depend on your location. For most of us this will still be a "no," but if the OP is in one of the special markets (LA, NYC, ATL) you can see it. Since OP is in Oakland, I figured he might get lucky.
I swap cards a bit on mine (one SIMM or work, and one for personal use) and have been in areas where the EDGE network was nearly as fast as the supposed 4G on the other card.
I should probably start using the that bandwith meter app and record my results. It could be interesting.

EDGE is not generally considered a 3G technology, although it is a significant improvement over GPRS, and it offers speeds approaching true 3G speeds.
Calling EDGE "3G" is somewhat like T-Mobile calling HSPA+ "4G"; it's playing a little fast and loose with the definitions. I do agree that in ideal circumstances, EDGE speeds can be pretty good, but it really falters when it comes to streaming media or any other data-intensive task.

They get a tiller and replant the used seed.
TMobile uses 1900MHz for their old 2G edge network. They will upgrade the Edge towers to HSPA+ 3G.
For those that arent aware: If you use iphones or any other at&t phone with t-mobile sim, you notice this is the slow network you can use. The upgrade will allow you to use the at&t devices at HSPA+ 3G speeds... which is very inviting for at&t customers to transfer to t-mobile on the same handsets they already purchased. Or IPHONE/IPAD fans to use t-mobile services.
Just curious, anyone familiar which areas the refarming is being deployed first?
I'm in NJ and would like to get the One X, but not sure if NJ/NY will get refarmed first. Although I recall when HSPA first rolled out, NJ/NY got them sooner than the others....
I'd like to test out my sim with an unlocked iphone, but my iphone is 1st gen, meaning no 3g capability at all lol.....so if anyone can test please let us know.
