HTC Magic (Vodafone UK) - Trying to get 3g in the states?

I have just taken a job in the states and brought my phone with me. I was expecting to be able to get 3g when I insert an AT&T or T-Mobile sim card. Unfortauntely the best that the phone seems to be able to get is Edge.
After doing a bit of research it seems that in the US they are using differnt frequencies.
Does anyone know of a fix which would allow my phone to get 3g in the states?

T-Mobile are, I think, UMTS 900 / 2100 (perhaps like Vodafone in the UK and elsewhere, which is why we can all use T-Mobile-based rooted HTC ROMs in our phones).
AT&T is UMTS 850 and 1900.
At the moment no phone on earth can do both UMTS 850 *and* UMTS 900. These frequencies are used to provide longer range coverage in low-density service areas - in other words, most city-edge and countryside places.
UMTS 1900, 2100 and other higher numbered frequencies are used in higher-density areas to provide more calling / data capacity, but with the downside of more limited range.
It seems (googling) that AT&T do 850/1900 and T-Mobile do 1700 (as of May '08 sez Wikipedia), though the T-Mobile MyTouch3G does 1700 and 2100....so maybe T-Mobile now do 2100 as well (at least in some places). There doesn't appear to be much, if any overlap on 3G frequencies between carriers and users must be EDGE only on the telco that doesn't match their phone. Everyone does EDGE.
In New Zealand, where I am, one carrier does 850 and the other 900...but they both support 2100....and a 3rd carrier will soon be offering 2100 later this year.....so you do get *some* 3G on just one phone in built up areas where telcos need more capacity and use 2100....but you get nothing in the countryside and have to used EDGE/GPRS.
There are about 7 UMTS frequency bands all up (Wikipedia).....so any single device is going to be seriously challenged to support all those well.....and what telco would want their phones to do that anyway? Frequency incompatibilities prevent their customers from leaving.......which explains why there aren't any phones that do all 7.

If Vodafone (UK) & T-Mobile (US) are using the same UMTS frequencies, does this mean that I should be able to get 3g in the states? I am currently using a T-mobile (US) sim card but the phone is only getting an Edge connection. Maybe I need a ROM update??

maybe your in a area with no 3g coverage?
go to t mobiles website or better yet go here
http://coverage.t-mobile.com/default.aspx?pageType=idealer
and press the data coverage tab....are you in a purple place?

I checked on the t-mobile site and Tampa, FL appears to be all purple.

Have you checked your settings?
Settings -> Wireless controls -> Mobile networks -> Make sure 2G only is "Un-ticked"
If it doesn't work, maybe you would like to consider selling your one on ebay and buying a Magic {or other handset} from the US

[Q] Telstra Australia AP settings & speed ?

Hi all,
Mostly a lurker here over the years, love the site and forums - great community! I'm running latest JG4 Optus on my SGS with the new "2200 score" lagfix - awesome!
Anyone else getting really slow data on Telstra? I have tried telstra.wap telstra.corp telstra.internet telstra.iph all of these AP's give extremely slow data, and the phone symbol at the top flicks between 'H' (assume HSDPA) and 3G at times. I'm talking 0.4mpbs.
My friend is on Optus and his *cough* iPhone is getting 4.45mbps, in comparison my speed is nowhere near this speed. I am in metro Melbourne.
Anyone else have slow Telstra experience or know a trick or setting to help out - would be much appreciated!
Thanks all.

i could be wrong, but i dont think the galaxy s supports telstra network very well, if at all. dunno, not real tecchy, but its what ive heard round the traps. something to do with the bands the phone supports (900/2100 or 2200ish) and telstra is 850 something or other. smarter people than me will be able to clarify.

Correct, Telstra uses 850mhz and 2100 (apparently). But, only some variants support 850, and Telstra are releasing their own for that frequency. So I'd imagine that 2100 simply has lower coverage (Optus on the otherhand uses the more standard 900mhz frequency).
If you already own the phone, you may wish to consider moving to an optus based network (such as Exetel for Virgin). However, it is also entirely possible/probable that the galaxy S ships with a chip that supports 850mhz, and it simply needs to be enabled (I have seen threads which showed a way to apparently enable it).
Or, it may be just reception probs

Hi, thanks for the input...
According to http://www.samsung.com/au/consumer/...dex.idx?pagetype=prd_detail&tab=specification the phone does support 850 and 2100. Strange

It possibly does, but which country did you purchase it in? Remember, some countries might have had it disabled (because they don't use 850, or have other services on those frequencies).

Hi Andrew Purchased in Australia from Allphones "unlocked". Tried the 850 band turn on and various other fiddles in that debug/phone settings area relating to 3G and HSDPA - unfortunately the max I've seen on Telstra is 0.40Mbps, my friend gets 4.45Mbps on iPhone/Optus
Coverage in my area is usually great, I'm in Melb metro area and normally full bars.

mate it might be worth a look over at whirlpool forums, they seem to have a fair bit of stuff about telstra and the galaxy s over there, so you should hopefully find some help

Hi, thanks for all the information, heres the low down:
Telstra has WCDMA 2100 and 850 bands, but the Galaxy S badged versions of this phone only support quad band in GSM, it is triband on WCDMA and unfortunately 850 isn't supported Telstra will be selling a different version of this phone shortly ("Captivate" badge!?!?!?) which WILL support their 3.5G 850 network at full speed.
Bummer!

US T-Mobile's 3G freq vs the rest of the world?

Anyone getting the T-Mobile version tomorrow? With CDMA not SIM capable, and AT&T version still up in the air, I think I'm probably going to get one tomorrow!
I've got question regarding T-Mobile's werid 3G band tho. I think Samsung listed T-Mobile's version as AWS 1700/2100. I know 1700 is weird, but is that AWS 2100 same as the 2100 band that the rest of the world use? Sorry it's my first 3G T-mobile device, and looking on wiki or google is just kinda vague

2100MHz is the band used all across Europe as well as large parts of Asia.
So, yes, the T-Mobile one should give you 3G capability in other parts of the world, though if it's locked that may open up other issues.

I had a TMo US G1, and it worked fine on 3G when I returned to the UK. The converse was not true of my TMo UK G2 (HTC Hero), which would only get Edge in the US because it did not support both bands of AWS (1700/2100).
So, I see no reason why a TMo US shouldn't work pretty much everywhere else in the world where 2100 3G is ubiquitous.
Regards,
Dave

Cool thanks, i guess that AWS threw me off. I thought there were a regular 2100, and then T-Mobile's AWS 2100

Actually you're a bit off. Tmo's 3G runs on AWS 1700/2100 band which is not the same 2100 *frequency* as the rest of the world. Tmo uses 1700 for downloads and 2100 for uploads, so both bands (aws/band IV) are needed.
Now Europe (and rest of GSM world) use straight 2100 band for 3G but the exact frequency is not the same as Tmo's.
Basically a Tmo Galaxy Tab will only get you EDGE outside of the US. An ATT Galaxy Tab will get you 3G in the US and the rest of the world (as long as it's sim unlocked, ofcourse).

No, the T-mobile phones give you also 3G in Europe. All AWS chipsets do both Band I (2100) and Band IV (AWS 1700/2100).

I thought the galaxy tab is quad band, so you can simply swap your sim card with another european carrier and it should work on thier frequency
Am I wrong?

You're right for 2G, not for 3G

So getting the unlock code for tmobile device and putting AT&T sim card will not give me 3g connectivity (using AT&T network)?

No, because it doesn't support the 850 or 1900 MHz bands.

One could say the same to you.
This is a link to T-Mobile US's support forum, in which someone has had it confirmed from T-Mobile themselves that all devices designed for their network have to be fully compatible with the 2100MHz band, meaning they will give you 3G capabilities in Europe.
Your previous post in which you claim that the 2100MHz band that T-Mobile use is not the same as the 2100MHz band the rest of the world uses is nothing short of ridiculous.
If the band T-Mobile used was different to the one used in the rest of the world, it would not be described as 2100MHz.

Sorry, but as I already said earlier in this thread, my T-Mobile US G1, which is an AWS device, worked perfectly well in the UK with full 3G. Similarly, I know of people who bought TMo Nexus Ones in the US, and these all worked fine in the UK.
That's not to say there isn't some subtle difference which not all chipsets can cater for, but it is certainly true that many TMo US handsets will give 3G capabilities in Europe.
Regards,
Dave

The normal UMTS 2100 is called "Band I" and t-mobile's AWS is called "Band IV":
http://en.wikipedia.org/wiki/UMTS_frequency_bands
The AWS 3G module has already 2100MHz support, so there is no additional hardware necessary to support Band I as well. Theoretically it could be disabled, of course, but then T-mobile wouldn't be able to charge you an arm and a leg if you were to roam outside of the US

USA AT&T Galaxy Tab questions answered here

I created this thread because there seems to be some confusion as to the differences between the T-Mobile, Euro, and (soon to arrive) AT&T branded versions of the Galaxy Tab. I'm sure at some point enough information will exist for a proper XDA wiki entry, but for now, we need a thread for each variant with specs, and where possible, hack/flash options, including phone and data connections.
So this will be the US AT&T thread, where we can get the facts straight for those who wish to use AT&T as their carrier with a Galaxy Tab.
THIS THREAD IS FOR US AT&T GSM ONLY, DISCUSSIONS ABOUT CDMA (SPRINT, VERIZON, ETC) SHOULD BE IN ANOTHER THREAD!
Other carrier-specific threads:
US Tmobile Galaxy Tab flashed to make phone calls (currently phone works only, no 3G data)
(I would suggest to moderators that other non-AT&T and CDMA-related posts be removed or moved to a more appropriate thread.)
Alright, for starters, let me post the US AT&T frequency information, so that n00bs can be up to speed.
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/WCDMA/HSPA 3G
1900 MHz UMTS/WCDMA/HSPA 3G
This should be helpful when we discuss the Galaxy Tab specs. I will be re-editing this post as new information comes in.
[future verified information can be placed here]

[reserved for FAQ]

[reserved for links as needed]

Actually, the SGH-I987 version that AT&T is getting has already launched. In Canada. On two carriers.
The Bell version has two model numbers on the back, the GT-P1000M (firmware is different, and presumably less crippled than what AT&T will release, hello sideloading), and the FCC model number of SGH-I987 on the back cover, so the internals are identical to the AT&T unit.
And you missed a few bands, any Galaxy Tab with a SIM card will work on 2100 UMTS as well as 900 and 2100 GSM/GPRS/EDGE.

AT&T should be releasing their branded version of the Galaxy Tab on the 21st (just a few days from this posting). If I understand right (this is where the value of this thread will come into play), the specs for the T-Mobile version are different in terms of the 3G radio frequencies.
IF this is true, then it would mean that if you plan to use AT&T as your US carrier:
You must run an AT&T branded Galaxy Tab
You must run a Euro-spec Galaxy Tab*
*specific procedure for this to work is unverified at this time
Price
At this time, the price for an AT&T branded Galaxy Tab will be $650 from AT&T. It will have two pay as you go plans--$14.99 for 30 days and up to 250MB of storage or $25 for 30 days of up to 2GB. This is similar to how they currently handle the iPad plans.
HOWEVER, as many people here on XDA-devs know, it has always been possible to take a GSM SIM and move from phone to phone, and provided that the frequencies are compatible, the services should carry over and the device change remains largely in the control of the owner. Of course, they can detect the IMEI at the carrier, but in most cases they are not blocking IMEI's. If your device has the right radios and frequencies, it should work. In the past, this has been the case with most devices.
So the question is: Does the Euro-spec Galaxy Tab have the same frequencies as the AT&T branded Galaxy Tab? It should, considering that the specs for the Euro version seem to reflect the same frequencies that AT&T uses.
In theory, getting the software right on the Euro-spec Galaxy Tab should be a matter of flashing a working cooked ROM to enable phone and 3G connectivity.
As of the time of this post, one or two people have managed to get a Galaxy Tab phone service working with AT&T, although I am unsure about 3G.
Again, the purpose of this thread is to clear up these questions, and keep it focused on getting a fully-functional Galaxy Tab on the AT&T carrier. Meaning both phone and 3G working as normal with any other device.

I can confirm that the European Tab works fine on at&t with full 3G and Voice dialing.
It is model GT-P1000
FCC ID: A3LGTP1000
I have been using it for the past few weeks and it seems to support all the required frequencies. It has operated in every mode including (G)PRS, (E)DGE, (3G) and (H)SPA

Stupid question then. Doesn't Canadian Rogers use the same frequencies as AT&T?
They sell Galaxy Tab too right? Does their Galaxy Tab have voice call capability?
I am interested in buying Galaxy Tab that could do 3G on AT&T and can make voice calls so I could use it as my phone ;-)

Interesting news... I bought an unlocked device in Kuwait City and it matches that FCC id number, but it had some Arabic apps loaded onto it, does this mean the euro and middle east versions are the same?
Also, how much of AT&T's network is is 850?? I didnt think the 3G would work back in the states... btw, my home is in the DC area is that helps.. Thanks!

The FCC docs actually say that the GT-P1000L, N, T models do support 850GSM and 850WCDMA(3G):
Type the device's FCC ID info in, (A3L is the manufacturer code for Samsung). Look at the documents in the 824.20 (GSM "850") and 826.40 (WCDMA "850") lower frequency ranges.
The actual test report docs list GT-P1000L and GT-P1000N and a clarification doc from Samsung says the GT-P1000T model is just a renamed L one.

This is great, it's exactly why I wanted to start this thread. SO, one person at least has a Euro-spec (GT-P1000) machine wortking with voice and 3G data on a US AT&T network.
Someone needs to post specs on the GT-P1000. Because right now, it would seem that the P1000 is the best bet for those who want to use FULL functionality on a US AT&T network.
My personal motivation for this thread is to get solid information on what model Galaxy Tab will have full US AT&T functionality (voice and good 3G data connect), and HOW to achieve that (choosing the right Galaxy Tab and flashing the right ROM). Once this is nailed down, I'll buy one. I just need to know which to buy and what to do to it.

Not FULLY working on at&t's 3g network. The 850 band for 3g is still missing and 850 is their primary 3g band and it's slowly replacing the 1900 3g band. The reason they changed was because the 850 3g band can cut thru walls better and give you a better 3g signal. I remember when my area had only 1900. My 3g sucked. Very spotty unless I was outside. I instantly noticed when the 850 upgrade took place. Solid 3g even in the darkest areas of my basement @ work. There will be an unlocked 850/1900 3g band version on the tab but it looks like it was pushed off until early 2011. Probably because they knew they would never sell any of the current north american models with the 850/1900 3g bands (bell, rogers & at&t) For what it's worth, you can pre-order that version here:

Who said at&t's primary 3G is 850Mhz?
That is just false information.
Their primary is actually 1900Mhz and they are beefing it up with new 850Mhz towers, not instead of current 1900Mhz existing in infrastructure.
Places who only recently got 3G service might be on 850Mhz but all those who got 3G up until 2 years ago are all 1900Mhz with the addition of 850Mhz.

Yea this article and all the others stating the same are copying the same wrong source.
At&t never said they will be replacing 1900mhz with 850mhz...they said they will be ADDING towers and expending their network on 850mhz.
Here in the sf bay area the netwrok is mainly 1900mhz but they are ADDING new 850mhz towers so now we get mixed frequencies in places where signal was bad. They are certainly not removing 1900mhz towers.
Sent from my GT-P1000 using XDA App

This thread encapsulates my concerns exactly. I want to use my tab as a phone, and am on ATT, so will wait to see how to best implement this agenda before purchasing anything. I have a couple of concerns:
1) I think that the Galaxy Tab forum should be split amongst various carriers, since future roms and such will likely be device specific.
2) Now that more information is coming out with regards to the Nexus s and Galaxy 2, I am wondering whether I should hold out. I do want a large screen, but the development community/google support for the next Nexus phone is hard to pass up... maybe I will buy both!

Regarding splitting up the forums, I don't think that's a good idea. We tried it for the Galaxy S models and it is something of a clusterfuck, and not as much knowledge is being shared IMHO.

Data on TMobile G2 w/ ATT gophone

I was wondering why I can only get EDGE on my TMobile G2 phone... is it because of the GSM incompatibility that some TMobile phones have with the ATT network or am I doing something wrong?

Does your phone support 1900 MHz UTMS? That would be a problem. If it does then use *#0011# and make sure the bands are unlocked.

I got "connection problem or invalid MMI code" when I ran that.
Edit: Did a bit more research and it turns out that it does *not* support 1900 MHz UTMS for 3G, so basically, this phone + ATT network = no 3G service, as the hardware is incompatible.

Someone doing their own research? Get the hell out.
Actually, I don't think the G2 even does 3G on anything but AWS. The HTC Desire Z (identical but without carrier branding) has a version that supports AT&T 3G, however.

Can you explain what you mean by "use *#0011# and make sure the bands are unlocked"? My Samsung phone can't get 4g service here on T-Mobile and it doesn't do 3G so I'd really like to enable HSPA+ if that's possible. I don't see anything on that screen that I can unlock though.

Check which UMTS (3G) bands your phone supports - I suspect yours does not support T-Mobile's 3G band (IV). The information is usually available on wikipedia or gsmarena.
You do not "enable" 3G through software changes. Your phone supports it or it doesn't.

It does support band IV, 1700Mhz, but it doesn't do HSPA+ so it can't get 3G. That screen still doesn't tell me anything though.
GSMArena says it has 3G Networking on HSDPA 850 / 1700 / 2100 / 1900 but that's not true. There is no 2100Mhz band, not on mine anyway. Actually GSMArena isn't very complete or very accurate, it don't even list the model T959V!

That's not how HSPA+ works - it's essentially just faster 3G. Also, I found your phone on GSMArena, not sure how you searched but the information is all there and it supports band IV (1700/2100) and I (2100).
Are you sure you've enabled 3G (or deselected "Use only 2G networks")?
What is the history of the phone (bought new, used, etc.)? It should "just work" on T-Mobile as it's T-Mobile branded but, no offense, your details are a little vague.

Sorry if I was vague but it doesn't "just work" on T-Mobile! At first I though all Exhibit II models would be the same however they could have different versions like the Galaxy 2 that has an older version for 3G and a newer version that also now gets 4G, who knows.
The phone was purchased new a few months ago and is still stock. I know HSPA+ is faster 3G since I can get it on 1700Mhz on another device using the T-Mobile SIM from the Exhibit 2. Can't get HSPA+ or 3G on the Exhibit 2 though.
Yes the phone is on GSMArena but the info is not accurate, it claims the phone gets 3G and has a 2100Mhz band but that's not true. It only supports band IV on 1700.
There is no option to enable 3G or "Use only 2G networks". It has options for WCDMA (for 4G on 1700) or GSM (for Edge on 1900) but there is no setting in between for 3G or HSPA+. I tried setting it to WCDMA only but it defaults back to Auto using Edge unless I go to a T-Mobile store where they have a strong 4G signal that gives 5 bars. If I leave the store and go down the street there's no signal though.
I have verified that WCDMA for 4G is on 1700 and GSM for Edge is on 1900 using a spectrum analyzer but it never uses 2100 and has never used 3G anywhere in the Phoenix, Mesa or Scottsdale area, just Edge. There may be other modes and frequencies but I haven't been able to verify them.
If there is a way to turn on 3G I'd like to know what it is? Someone suggested dialing *#32489# clicking #3 then UTMS but that didn't do anything.

I don't know where to begin but let me get this straight...
-You bought a new Exhibit II from T-Mobile.
-It doesn't get 3G outside of the store.
-Your other T-Mobile compatible device gets 3G outside of the store.
-You've owned this same Exhibit II which hasn't been connecting to 3G for months.
On these points alone, am I understanding you correctly?

Close but not quite correct, it doesn't get 4G outside of the store.
It can't get 3G at all anywhere!
Since there is no 4G network is there a way to turn on or enable 3G or is it hopeless?

In a previous post you said that you "know" what I'm talking about but clearly that is not the case.
What T-Mobile calls 4G is actually 3G with improvements to the backhaul as well as the radios on the phones - where T-Mobile has 4G, it also has 3G.
The point of my last post was to make it obvious that you have a defective phone. I shouldn't have assumed you would figure it as you haven't figured it out in the months you've owned a phone that obviously has reception issues.

Again not true! What they call 4G is using WCDMA but 3G is using HSPA+. 3G using HSPA+ has improvements that will allow it to go up to 20Mb but my Android phone doesn't have an option for 3G, just 4G using WCDMA. The people at the T-Mobile stores would beg to differ with you about the phone being bad since I've been to 5 T-Mobile stores and they say the phone works OK since it can get 4G on 1700Mhz in the store.

Your posts are too long to be trolling, but it still feels like you are because everything you post is wrong.
In case you're not trolling:
-Your phone has hardware defects that are affecting how well it connects to 3G.
-The fact that you get reception in stores is likely because stores have signal boosters.
-Retail employees are idiots. They are trained to use the products just enough to sell them (read: not much) and aren't paid enough to attract anyone with half a brain to the position. Walk a block away from the store and show them that your phone doesn't connect to 3G (or "4G" if you still want to call it that).

Both of you are feeling like you're trolling.
It may be a tower issue or your phone. The only way to check is to use another phone.
