Hello,
I recently bought a HTC HD2 and gotten unlocked to work with my ATT sim card also I had someone install the 2.2 Froyo Android software using Cyanogen Mod 6. Since I had the phone I have only been using Edge network and I know for sure we have 3g coverage. How can I get my 3G network to work on my phone? Please help. I am a newb when it comes to cell phones.
Thanks
Matt
someone correct me if i am wrong but the 3g bands for att and t-mo are different so even if you have 3g coverage you would only get edge. For faster speeds youll have to use wifi.
Do you have a Telstra-branded HD2? IIRC, Telstra uses the same 3G bands as AT&T. In that case you should be able to get 3G. Otherwise, the unbranded & T-Mo branded HD2s wouldn't work with AT&T 3G.

I don't know how to check that but this HD2 used by a previous ower having Tmobile. Still having the same problem. Any help is appreciated.
thanks

Unless you have the Telstra HD2 (there will be a T in an oval on the back bottom cover), you won't get 3G on ATT. The Telstra model is the only one with the ATT 3G band (the 850mhz UMTS band).
You will ALSO need to have 850mhz ATT coverage in the areas where you live and travel to get 3G on that model.
Hope this helps...
Hi!
I was wondering if there is a way to change that? Installing a new ROM, a software or something!! I bought the TMo HD2 and brought it to South America. Here we use the 850 MHz frequency for 3G, and I just found out the HD2 works with 3G networks in the 1700 and 2100 MHz frequencies =( Is there a way I can change that ???

I checked and there is no T on my phone or cover. But I have cyanogen Mod 6, I was wondering if anyone else has this problem.
thanks
Well, i was searching and i noticed that here is no section here for the 3G GSM version of ATRIX, just the 4G US version.
What about the european or south american (or even asian) versions? Does all this custom roms works for them too?

They are the same device essentially, and I'm pretty sure they're 4G enabled, just worded differently. They support HSDPA 14mbps (Cat 10) / HSUPA 2.0mbps which is HSPA in the US I think.
just the at&t atrix is currently unlockable but likely the international ones are getting unlocked with update so currently it is just possible for at&t atrix to flash custom roms, and the thing with the 3g/4g naming is region specific but the same hardware.
Here in germany 4g is lte, actually lte is called 3.9g so we don´t even have 4g

Fixed that for ya!
It's the same phone
Just switches automatically to 3g. But in EU the carriers have very expensive prices for hdspa connection. So i use it in 2g mode (leeeesss of battery consume).
Ok thanks to all of you very much. I'm a little outdated about wireless technologies and i tought 4G was cdma-based stuff. So hsdpa-hsupa are 4g gsm based technologies? I can flash my atrix with a custom rom with no problems?
Another thing that bothers me is all that acessories that comes in the pack. Remote control, dock, hdmi... will all this stuff work with the custom roms?
One last thing: Can i use it on hdmi without that "hdmi modes", just displaying whats on my screen like a game or movie, like i do with my xoom?

Just out of curiosity, do all Atrix use the same 3G bands?
If not, wouldn't that affect software porting?

but th eofficial specs on motorola's website say 14.4 down and 2.0 upload, not 5.76. are you sure its 5.76Mbps HSUPA?
The Atrix can't use 4G on tmobile.
Can the new roms with the unlocked bootloader change the radio frequencies to work with tmobile's network?
or
Is this a hardware problem?
No unfortunately it is a hardware limitation.

Yep, the ATRIX radio doesn't have the band needed for T-Mobile 4g.

Im having the exact same problem. Except im using an ATRIX on att :/
Is there a prepaid service that could provide 4g or at least 3g speed for the Moto Atrix?

Are we sure it is hardware? The specs say qualcomm mdm6200 which via software (as per the qualcomm data sheets) is able to use umts 1700/2100 bands(ie AWS bands).
Let me grab the links.

On the Qualcomm datasheet, I found frequencies beginning on page 111.

I was reading the pin outs and that is where I determined that there are no seperate pins for AWS or well any band and so I would assume the frequency is baseband determined.
If anyone is still looking. Pages 102 through 104 is interesting as it gives the pin outs that need to be programed in software for the correct bands. If anyone knows how to break open a radio firmware or program the radio that would allow us to get all bands working I think. This would also possibly allow for targeted radios that use less energy since they only rx/TX on the frequency that is available in that location.

Look at the bands in the specs - if you don't see UMTS1700, it won't work.
And I have NEVER seen that in the specs for ANY AT&T phone, EVER.
In rare situations, T-Mobile phones supported one (but not both) AT&T bands, but I've never seen any AT&T phone support T-Mo bands.

T-Mobile's AWS bands aren't typically supported. AWS isn't even used in Asia or Europe. T-Mobile's SGS2 does have AT&T's bands but not vice versa. But it's a stretch even calling T-Mobile's version an SGS2.
How about 3G? Does Tmobile support 3G on AT&T phone, since i read both phone have 2100 UMTS.
Thanks

Vibrant only supported one of the bands (1900), so it only worked on att 3G in some markets, not everywhere. Some markets only use 850.

No. 3G and 4G use the same bands. You MUST have 1700 AWS support in order to get T-Mo 3G or 4G. Good luck with that. Only T-mo or some Canandian phones support AWS.

You'll get EDGE/GPRS speeds. Typically between 256 and 512K. To get anything higher you'll need a phone that supports 1700/2100 of which there aren't many other than the one's offered by T-Mobile itself.
Simple answer: No.
You will only get EDGE speed on any AT&T phones. There aren't many phones with 1700 band besides T-Mobile phones.
It's funny how T-Mobile's "SGS2" supports AT&T's bands, but not the other way around. But then again their "SGS2" seems more like an Amaze IMO since it's using the darn S3 & not Exynos >:l (points at tmobile). I really wished Sammy could fix the Exynos, so it could support Tmo, because it feels wrong when Sammy teams up with Qualcomm....End of rant.
The only reason T-mo version uses Qualcomm chip is because it needs the 42mbps HSPA+ radio from Qualcomm. The upcoming LTE version of GS2 will also use Qualcomm chip because it needs to use the Qualcomm LTE chip.

The Korean Celox, on which the TSGS2 is based, is an LTE device and using a Qualcomm chip. The two recently announced Korean SGS2 models will be LTE and using a 1.5Ghz version of the Exynos chip. Samsung went with Qualcomm for the TSGS2 and Celox either to shorten time to market or the projected quantities weren't sufficient to modify Exynos. Evolutions of Exynos will continue to power Samsung's flagship phones and tablets starting with the G-Note and G-Tab 7.7.
Do these two phones have identical hardware but different firmware, so that flashing for example the CM9 mod would make them identical, or do their hardware differs from each other, considering different band support and lack of LTE on T-Mobile?
Thank you.
For the most part hardware seems yo be same... you may have to switch the modems though. Expect a common Cm9 base and then a zip flash for each service provider.

Hopefully there will be some good collaboration between the ATT/Tmo (and possibly some parts from Sprint/Verizon) devs since the hardware is so similar.
It opens up the possibilities for a lot more ROMs!
Actually my question was more about the possibility to use the devices across the networks using custom mods (e.g. to use the I747 on the T-Mobile network).
Thank you.

You can do this without mods but you won't have access to the 3g band on TMo just like TMo won't have access to the LTE 4g ATT Band...flashing a diff modem/radio won't give you the missing bands unless the hardware actually supports them and its just locked out...which currently isnt known.

It's a very valid question… the AT&T Galaxy S III is $550 out of contract; the T-Mobile version, $630.
If you're paying out of pocket, $80 less for what amounts to the same device (arguably, the AT&T one is better since it has an LTE radio) is nothing to sneeze at.
I am having the same question as well.
The situation here is the same to what I have as Rogers/Bell/Telus vs Wind/Mobilicity
I'd like the flexibility to use the phone across the network since the new carriers charge way cheaper than the big 3....
I suppose the hardware between the two model are identical. All support the same band 850 900 1700 2100 (AWS/LTE). Only the AWS version has the LTE radio disabled and HSPA 42 enabled???
It should work, the phone is locked to att thou. You will have to have it unlocked. But the skyrocket and the hercules were interchangeable between networks. But the international will not work on lte or Hspa.

So you are saying that that radio modules of these two phones are identical. Meaning that T989 supports LTE, and I747 supports the 1700 band (they just have to be unlocked).
I'm gettin mine unlocked and using it on straight talk t mobile. I need to get that hspa 42 workin. It's just software. From what I gather, once t mobile rolls out their LTE they may just release a firmware update enabling LTE on the t mobile galaxy sIII's. This phone is a seven band monster world phone. To such an extent that carriers are turning features off.

All the radio modules on this phone are integrated in the S4 processor. And the processor is identical. One would have to conclude, that yes, that is the case.
From a strictly electrical background the modem is software running on transistors which can handle being pushed to the frequencies T-mobile requires, so I would think that it would be doable with the right software. When a transistor has the ability to handle the current and frequency the rest would be a matter of software, I assume.
As for LTE I have no knowledge as to the hardware or if there its something missing in non LTEs.

I have unlocked (Sim Unlocked) my SGSIII I747 from Bell and it works with Rogers and all... however i do not have a micro sim from Wind or Mobilcity to test it... however i wiill go to a few stores to test it out... if it works... which i assume it should.... but there are so many factors that it might not....
However, if someone like tomin.... i cant rememebr his id can provide an interchangable flashable modem for the two phones i747 could be used on aws 1700 using the radio from t999.
See the chart on Wikipedia
Samsung Galaxy S III Model variants
I've looked at the specs sheet from samsung.com and it's the same thing.
Weve been arguing in the other thread about how t999 has msm8260 instead of a msm8960Sent from my cm_tenderloin using Tapatalk 2
Unlocked as in correect combination of software loaded on the phone to correspond with the carrier, not simply unlocking the phone. More like unleashing its potential.

It is interesting as its normally a possibility with Galaxy devices. This is a bit different since they have used slightly different models. We won't know until we get flashable radios and someone is brave enough to try to flash it on their device. I know with the Skyrocket I was able to flash a T-Mobile radio and get a 3G signal on wind (same type of network but in canada). The only limit was that you couldn't take a t-mobile version, flash at&t's radio and get LTE.

It would be great if we ca use the same technique to make i747 work with Wind & Mobilcity and make it just like T999
Any Luck>>>
it's good finally there's not that big of a difference in hardware and looks vs the Galaxy s2. too many variants makes it difficult to buy any accessories
