My touch slide on att?

curious to know if any of you guys have your my touch slide on ATT network?
Thanks.

No one has this on AT&T yet?

It just barely released on on T-Mobile. A lot of people aren't willing to pay $430 for a phone if they can't get 3G on it, and the rest are stuck in a T-Mobile contract.

ooh, so they can't get 3g if it's on the ATT network? 430? I've seen tons of them go for 380's, some unlocked as well.
Well, if it doesn't get 3g, I guess it helped me make my mind up to go with the Nexus One.
Thanks

my tmobile - my touch slide unlocked
Got my tmobile - my touch slide unlocked - but it wont get 3G on ATT - is there any way around this issue? is it a matter of the frequencies or what? perhaps someone can explain...

tmobile and at&t are on two different 3g frequencies. A quick google finds this information.

according to info i found on the net:
"In the U.S., T-Mobile and AT&T both use GSM technologies, but there are fundamental incompatibilities in their 3G services. AT&T runs its 2G and 3G services at 850 and 1900 MHz. T-Mobile's 3G service uses 2100 MHz to transmit and 1700 MHz to receive. "
Yet the htc my touch slide supports the following:
Frequency Bands GSM: 850, 900, 1800, 1900
UMTS: 2100
so should work unless article is incorrect -- can someone post the att and tmobile frequencies?

Just with the G1 and mytouch, these phones are specified to use certain bands for 3G and certain bands for edge/2G. This is a Hardware thing. It can support GSM: 850, 900, 1800, 1900 UMTS: 2100, (and 1700 I assume should be in there since tmobile uses 1700 for 3G) But the hardware is built to use ONLY 1700-2100 for 3g.

Could you let us know where you got it unlocked and for how much? There are two phone companies in Canada - Mobilicity and WIND Mobile - who have the same 3G frequencies as T-Mo but no Android phones! And we would love to know where to unlock the MT3G Slide. Thanks!

I have seen plenty that are unlocked and for sale on eBay for roughly 380ish

Can anyone confirm that a particular web site's unlock code worked for the MT3G Slide?

why would you unlock it to use it on a inferior network? especially because 3g will not work EVER! the phones frequencies do not support att 3g

I can't speak for the AT&T poster's intentions, but *Canadians* would unlock it to use the phone on WIND Mobile, Mobilicity and soon Vidéotron, which are all AWS carriers. This is why I'm trying to find out where to unlock the phone successfully.

Ebay it man, they're going unlocked there for about the same as new/no contract at tmobile
http://cgi.ebay.com/NEW-Sealed-Blac...Cell_Phones&hash=item3cadeffd9b#ht_500wt_1154

Well I figure I'd rather personally know where it came from and unlock it myself. =)

I got my mytouch slide unlocked by blowfish. Email him at [email protected] it cost me $10.50 to get my phone unlocked.

I'm using the slide on a regional carrier that uses the same 3g frequencies as t-mobile. Just because the other major US players don't use the same ones doesn't mean no one else does.

I used cellunlock.net, with 50% off coupon (easy to google, there are lots of them), it was only $10, got the code in 2 hours both times.

Vibrant 3g on ATT

I have been reading on Howard forums on here on xda and can not get my vibrant to switch to 3g on my att service.
when i open the service menu with my att sim card in i am greeted with "RAT Selection Option is Restricted" under the band selection menu.
Without my att sim card in i can select 2100, 1900, 1700, 850 under the WCDMA menu
I live in an area that supports the 850 and the 1900 frequencies.
what am i doing wrong?
Thank you

You do not have to do anything in the phone to get AT&T 3G in the Vibrant. If you live in an area where AT&T is using the 1900mhz spectrum you will get 3G. IF you are not getting 3G is because they are using the 850mhz and the Vibrant can not get 3g from that band.

what the person above me said, although you can choose the 850 3g band on the vibrant, it doesn't actually work. Chances are your area is 850 not 1900, and att is planning on upgrading all 1900 areas to 850. good luck.
one last possibility i just thought of, maybe you have a really old sim that doesn't support 3g?

i did a test run up to another major city and bam! full 3g. A few test runs of it and i was pulling 400-515kb/s down and 90-100kb/s up. Just amazing. I might actually buy a att phone with those speeds! edge is currently at 20-22kbs down by 5-15kb/s up. I just really like never having a contract.
My city is newer and smaller so it does not have the 1900 band. however according to wikipedia there is a Canadian version that does. but meh, i change phones so often its not like i wont find another diamond. I only bought my g1 because of xda, same with the hd2, and the vibrant.
It makes me drewel thinking about a windows 7 phone + android. Only because w7p has some amazing games. But doubtful since tegra will not have an open source driver, as far as i can research.
Thanks guys. your amazing.

With my Vibrant on Tmo's 3G I'm getting 5922 kbps down & 611 kbps with latency @ 78 ms.
Alot of home broadband stats can't compete with these 3G stats.
I just wonder how much faster a G2 could realistically run in my area.

vibrant problems
I too have a Vibrant on ATT. ATT is running 1900 in my area and my vibrant gets it fine, for a few minutes. If i turn the vibrant off and back on ill be on att 3g for a good 10 minutes at blazing speeds, but then it switches to EV and never comes out of it...any ideas?

SGS & ATT

I'm looking to possibly get this as my 1st android phone - but I would like to be sure that you can get 3g on ATT in the US.
Any confirmation would be helpful.
thanks.
Edit: NM I found out the sad news

You're missing the point. GSM quad band is for 2G service only. In order to get AT&T's 3G service, you will need both 850 and 1900 UTMS/WCDMA band support. Obviously the current spec is for use outside of North America. If and when Samsung descides to bring it into NA, it has to add either AT&T's 3G band support or T-Mo (1700/2100) 3G band support.

Just for reference.

yes you can get the i9000m version and you get full 3G coverage on both 850 and 1900 bands
don't get the i9000 version as that is only 900 and 1900 bands

You don't need BOTH (850 and 1900) to get 3g. You can get 3g with just 1900mhz, but it's definitely preferable to have 850mhz and 1900mhz.
So get the i900m.

true and not true
only having 1900 band have a disadvantage
specially when you go underground or into buildings and areas outside of the big cities

What do you mean true and not true? If you read what I said, I am agreeing with you Did you not read my "but...." part?
You can get AT&T 3g with JUST 1900mhz. I didn't say it was great, but nonetheless you can still get it.

I didn't say anything about which has more.
I am simply trying to convey the message that a phone with 1900mhz 3g can in fact connect to AT&T 3g network. I am not saying or have ever said that you can get it everywhere where AT&T provides 3g service. Jeez.

Galaxy SII working in the US

Would anyone happen to know-
if I buy a Galaxy SII from Europe, would it work in the US? specifically with T-Mobile?

As I understand it, yes. But only with the EDGE network. 3G and 4G frequencies are probably different. Could be wrong.

This is the band T-Mobile USA uses: AWS, or UTMS. I don't think it would work, seeing the Galaxy S II's specs. I believe it has to be capable of both. I think best case scenario, it works like an unlocked iPhone and you can get Edge, but not 3G, much less "4G."
While the Galaxy S II supposedly works in both bands, I believe that in order to fully function with T-mobile USA's network it has to support both at the same time. Like I mentioned before, that's called AWS, and it seems to me it would have to be explicitly written in there as a supported band.

So what other carrier would support this device?
btw, thanks for the info!

At&t uses 850 & 1900 for data.
The SGS2 has 850, 900, 1900, and 2100.
It should work on t mobile, but I don't know the network bands off the top if my head.

I had to post because I saw alot of misinformation.
The GS II will certainly work in the United States.
It is a Quad Band GSM phone w/ EDGE data. It will also work on the 1900 WCDMA 3G band. At&t, Telus and Bell ALL function on the 1900 WCDMA band.
So yes the GS II will work with 3g on the 1900 WCDMA band here in the states and in Canada. You only need one 3g Band either 850 or 1900 will do. Best to have both so check your coverage area. I have a Galaxy S and have constant 3.5G HSPA signal with 1900 WCDMA only band.

I looked up the network bands. This is how it is:
Voice/calls/texts/etc. will work 100% fine on both of them.
As for 3G:
SGS2: 850, 900, 1900, 2100
AT&T uses 850 and 1900. 3G will work perfectly.
T-mobile uses 1700 and 2100. Apparently their network is retarded and you need both.
Sent from my Captivate.

Wrong again
T-Mobile uses 1700 paired with 2100 commonly referred to as 1700. A phone with 2100 will not work on T-Mobile... A phone must have 1700 to work on the T-Mobile USA 3G network anywhere in the USA. This phone will work on the 2G network and IF T-Mobile has any 1900 3G towers it could connect to those (I'm not aware of any at this time).

not until t-mobile has completed refarming its 1900 frequency to HSPA+ ...at least for the international and AT&T models. im not sure about the Sprint version.

I heard that the Sprint variant of the S3 has a sim slot since its an international phone. All you have to do is root and unlock it and it should work on T-Mobile 4G.

That's not an accurate statement but it makes the point—non-T-Mobile GS3s won't work on T-Mobile's 3G/4G until they redeploy from 1700 to 1900 MHz.
T-Mobile hasn't put out a time table. AFAIK parts of downtown San Francisco (around the Moscone Center), parts of San Diego, and parts of Birmingham, Alabama (i.e. relatively nowhere) are the only places TMO has this configuration deployed.

That's not exactly true parts of Bellevue and Seattle Washington have been reformed too so I'm sure there's more areas

Look up t mobile 1900 mhz refarming. Thats ur best shot. Other than that right now signs are pointing to no hardware support for t mobiles currnt hspa bands. Basically, cross your fingers that tmobile changes to your frequency in your area with this phone. Tmobiles doin cuz they want to steal awayviphine users so they do have incentive.

tmo:
850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band V (850)
i got 4 questions:
1) what frequencies does the tmo version work on.
2) what are the frequencies that at&t uses for its SGS3.
3) what frequency does tmo use for its 4G (internet) network.
4) when LTE comes out next yr on tmo, will samsung release a new line of SGS3 specifically for tmo to work on its LTE?

Never, probably… I don't have a source (you can Google it) but T-Mobile does not have enough spectrum in NYC to do much shuffling.

1) It works on the frequencies you posted. Let's rewrite that:
GSM/EDGE (aka 2G): 850, 900, 1800, 1900 Mhz
UMTS/HSPA+ (aka 3G/4G): 850, 1700 (aka AWS), 1900 MHz
Is it less confusing now?
2) AT&T uses 850 Mhz and 1900 MHz for their HSPA+ service.
3) TMO as of July 2012 uses 1700 MHz for most their HSPA+ service. T-Mobile will support HSPA+ on 1900 MHz in some parts of the USA by the end of the year. Very few areas (T-Mobile has only officially disclosed a tower near the Moscone Center, in San Francisco) do so now. Concrete details are sparse and nonspecific.
4) Next year is a long time—the SGS3 will be old by then, and the Galaxy Note 2 or SGS4 will have been announced. Nobody can predict the future. But, looking at the past, TMO released a new "4G" version of the Vibrant, so it's also likely they release new "LTE" versions of their phones.

one last question.. do you think that if i got the tmo version of the SGS3 and when LTE is released that the phone will no longer use HSPA? when LTE comes out, will the phone no longer use fast internet?

Yeah… that's a complicated question whose answer I don't yet understand myself.
TMO is doing their 1900 MHz refarming to free up 1700 MHz for use w/ LTE. Stuff I'm wondering:
What happens to older 3G/4G devices that don't support 1900 MHz? Do they lose their 3G/4G Internet? Note: the GS3 supports 1900 MHz, and does not have this problem.
How is TMO going to deploy in spectrum crunched areas (like NYC)? They don't have enough spectrum to move everyone over to 1900 MHz—does this mean 1700 MHz HSPA+ will be cut off when they bring 1700 MHz LTE online? Your non-LTE GS3 might lose 3G/4G Internet in this situation—but I doubt TMO would do this to anyone with a phone still in contract.
All in all, make your purchasing situation on the situation today. The next new thing is always around the corner.

But LTE is a gsm technology, currently sprints/Verizons phone (Verizon razr maxx works on international/att networks after a recent update) is a hybrid, but they have weird lte frequencies, I've read that all US carriers will have incompatible freqs, but qualcom is building a chip that does them all plus European ones.

It's simple, T mobile phone works on At&t HSPA but not LTE. At&t phone works on its own HSPA and LTE but not T moble 1700 HSPA. We've been trying to see if we can make it work on t mobiles 1700 hspa band, no luck yet. To make matters more uncertain. T mobile says they're refarming their 2g/edge spectrum to work on At&t's 1900 HSPA band. The At&t phone out of the box would be able to pick up this 1900 HSPA t mobile refarm. Although reports of this actually occuring are sporadic and they also fired the CEO who's plan it is a couple weeks ago. LoL. If you get that, that's the complete break down. So here you go:
T mobile phone - Supports both T mobile and At&t HSPA 4g speeds, no LTE of any kind.
At&t phone- Supports At&t LTE and HSPA only right now, t mobile HSPA "may" be available for it's antenna's in the future.
