Is there a way to change the 3G Frequencies on the G1 to support AT&T 3G network?
Nope, thats a hardware issue.
I thought it was possibly a software issue. If not, is there a way to change out the chip or the incompatable part to make it compatible?

Nope...not going to work for many reasons.
been answered plenty plenty of times.
From what I can figure a hardware change may not be required with the correct radio but we dont know the right radio without the right hardware. lol I know that makes no sense but it makes as much sense as anyone can make of it thus far. When its possible I assure you I will be among the first to do it. Although Im not ready to try installing a new radio without first acquiring a backup phone but if I do Im gonna give it a try and maybe have better luck than the last guy to try.
What about a mini-usb attachment that can receive atnt signals?
I am sure with that and the right software manipulation it could work.

While it sounds great in theory I doubt anyone would put forth the resources for such a limited market.
You would be best off getting android to work on existing AT&T hardware.
in order to do it we would need hardware which would plug in the bottom and software to tell the phone to use the signal from the attachment.
while there wouldnt be millions in the market i guarantee there are hundreds.
if anyone wants to think about it i dont mind making 50 of em and selling for cost. i have some hook ups in the engineering field i work in
ok, my question is... Europe 3g is diff than tmob usa 3g, but is tmob europe the same 3g setup as US? and if europe 3g is same as tmob europe 3g, is att US 3g same as europe 3g. so if tmob europe is same as europe 3g then a europe g1 should work on att US 3g. am i coming thru clear or am i jumping all over?

The American G1 has 3G support for HSDPA 1700 MHz & 2100 MHz, both bands I believe are used by T-Mobile. In Europe I believe they use only 2100 MHz band for 3G.
AT&T on the other hand uses 850 and 1900 MHz HSDPA
The phone has the capability for 2G at 850 and 1900 MHz, so technically it can be used on their network, just not at 3G speeds.
Although technically it's possible to design a Phase-Locked Loop to operate at a variable frequency and to be tuned with jumpers or something, it's probably cheaper for them or they might be subsidized to make phones so that they are exclusive for one network in the US.
To me the ideal is more about standardizing the protocols and the frequencies used for all companies, and having all bands available for traffic. But at least in the short-term that's not really good for business and so probably won't happen for a while.
This is all based entirely on a limited amount of research and my opinion, take it for what it's worth.
Europe uses 1900/2100 in a pair (1900 is the uplink, 2100 is the downlink). (source)
Most phones produced these days are tri or quad band and can work (almost) anywhere.. I'm surprised the G1 isn't.

*sigh*.
Folks, you need to learn about UMTS bands before complaining about that the G1 or any other phone can't do this or that when it certainly can.
The G1 is a 3g worldphone. It works on the US 1700 AWS network (UMTS Band IV) and works on the world's 2100 network (UMTS Band I). ATT uses the 1900 Band (UMTS Band II).
Apparently the common names for these networks is being confused with the actual operating frequencies because they don't upload and download on the same frequencies. The 1900 band is not the same as the 2100 band, even though the 2100 band (UMTS Band I) uploads in the 1900mhz frequency and downloads at the 2100mhz frequency range. The 1900 Band (UMTS Band II) uploads on the upper half of the 1800mhz and downloads on the 1900mhz frequency range. UMTS Band II uploads on the frequencies that UMTS Band I downloads.
These bands separate.
TMO 3g band is different from ATT 3g band which is also different from EU 3g band.
The 1700 band (UMTS band IV) is actually made up of 2 frequency ranges like the other bands I and II are: 1700mhz and 2100mhz. In fact, the 2100mhz download range for UMTS Band IV is within the same frequencies used for the Band I download range, theoretically making it cheaper/easier for manufacturers who make Band I phones to "support" UMTS Band IV phone production.
Most phones produced today are NOT "tri or quad-band" 3g phones. In fact, I have yet to find a quad-band 3g phone. If quad-band 3g phones were made, they would be very likely to support the T-Mobile 3g network, because it's the 4th largest UMTS band type (behind Band I, II, and V). I would be very shocked to find a phone which was 2100/1900/900/850 instead of 2100/1900/1700/850.
And the G1 is a worldphone. It works just fine on UMTS in Europe. It is a band I and band IV device.
read these 2 links:
http://www.htc.com/www/product/g1/specification.html
http://en.wikipedia.org/wiki/UMTS_frequency_bands#UMTS-FDD
So to clarify, when you see a list of support bands, this is what you should interpret from those advertised bands:
2100 Band = UMTS Band I (The entire world outside of North America)
1900 Band = UMTS Band II (The Americas, ATT)
1700 Band = UMTS Band IV (The Americas, TMO)
900 Band = UMTS Band VIII (Australia)
850 Band = UMTS Band V (The Americas, ATT)
Outside of North America, the 2100 band is almost universally deployed, even where the 850,900,1700 or 1900 band is deployed.
I have my us model sim unlocked, is it compatible with middle eastern bands (mainly Kuwait) and Euro bands (mainly Germany)?
Sent from my HTC Sexiness.
Well, it is if those areas you mentioned use, or mostly use, UMTS band I (2100 Mhz). Now, if they also use, or extensively use, UMTS band VIII (900 Mhz), then I am not sure. Every spec that I have found online has said that the TMOUS version supports UMTS bands I, IV, and VIII; same as other versions. However, the specs on the side of my TMOUS retail box say UMTS bands I, II, and IV; no UMTS band VIII. To make matters worse, the T-Mobile site does not even mention band II at all, just I and IV. So, I wonder where sites such as Pdadb.net, GSMArena.com, etc. get their information, and where can we get accurate information. Sorry that I can't give you a better answer. I wish I had one...lol
Hi guys,
I'm looking to buy a Galaxy SIII from the States to use here in Australia, and am having a hard time understanding the intricacies of the cellular bands. I get that CDMA stuff is a no go (Verizon, Sprint) and that it seems only TMobile and AT&T are possibilities. Here is a chart with the variants and their banding listed. http://en.wikipedia.org/wiki/Samsung_Galaxy_S_III
The variants support all 2g frequencies, but I don't understand how the 3g part works. The t-mobile one in the 3g band is
850, AWS (Band IV), 1,900, 2,100 MHz UMTS / HSPA+ / DC-HSPA+
Click to expand...
Click to collapse
, which doesn't include the 900 that some networks use here. Will the phone use only 2G if this is the case? Will that make any difference to me? Will the AT&T one work as well?
Can someone please give me some clarification? :victory:
Below is the info for Aus carriers...
2G
2G, other wise known as GSM, is standard on almost all phones (except CDMA phones in the USA). Most new phones come with quad band GSM support. A quad band GSM phone supports 850, 900, 1800, and 1900MHz.
2G is old technology and provides a fall back position when 3G coverage is unavailable.
Australian 2G bands:
900Mhz (Telstra, Optus & Vodafone)
1800Mhz (Telstra, Optus & Vodafone)
3G
There are several 3G networks operating in Australia. 3G frequencies are usually specified as UMTS/HSDPA or WCDMA frequencies on the mobile phone specifications.
Australian 3G bands:
850MHz (Telstra, Vodafone) – Exclusive 3G band
900MHz (Optus, Vodafone) – available in most metro areas on Optus, with both Optus and Vodafone re-farming the 2G 900 spectrum in regional and rural areas
2100MHz (Telstra, Optus, Vodafone) – Exclusive 3G band
Folks,
Please take a Min and help a me out. Me and wife are currently stationed and residing in Kuwait. Kuwait launched 4G LTE service late last year. The LTE network runs on 1800MHz band 3. the same Band as Telstra Australia, and O2 Germany. i have tired almost everything to get my LTE working, yet no luck. Now, the service run on the Iphone 5 and my LTE USB dongle with no problems.
List of things i tried.
1- flashed the following firmware
a- JB Telstra Australia
b- JB Orange France- LTE ON
c- JB SFR France- LTE ON
d- JB Retail Brazilian
Currently running JB O2 Germany
2- tired the service menu to switch to LTE and that didn't work.
3- Attempted to change the band but unable to select or change.
4- the SIM card work fine on the Iphone, so no sim issue
5- The service is activated
Sorry i think i posted in the wrong section. please move to the correct area
4G isn't really LTE. Since you said it uses the same band as used the other 2 providers you should be able to access LTE by flashing the correct radios or the whole rom & using an LTE sim
Sent from my XT925
Also O2 Germany has 800/2600 bands. From which carrier did you purchase your phone?

This phone don't have the 1800 MHZ band ... only 700/1700 mhz band There are two different phone ! One for north america ! One for the rest of the world ! This is just not a baseband question or rom problem... i have post it on many topic but many people think this is the same phone the Fido/Rogers support LTE in 700/1700 band .. and support only hspa to 21mbits ( no DC-HSPA up to 42mbits like others country ! )
Sorry ! You never get LTE !

Well. this just sucks big time!!!!! :crying: im glad someone have an answer after all
Just a quick thought. Did you check with your provider for a separate LTE APN?
I would probably be running the Telestra ROM to check this. Make sure your service menu reads "LTE/GSM/WCDMA". You can't select bands, but make sure it is "Automatic (2G/3G/4G)".
Looks like your phone should have the one that looks like "action.wataniya.com" (http://10.wataniya.com/customercare/configure/default_en_gb.aspx). Perhaps, also give them a call to check whether their site is up-to-date and this is the correct APN for their LTE network. Also, check your wife's phone. Is she using the same APN?
Just trying to help you troubleshoot.

Can you provide documentation? Motorola's site seems to suggest there is only one version based on their technical certifications. Which "model" are you using if I may ask. If you're using the "800/1800/2600" version, would you mind giving me the information on the back of your phone so I can dig up some info (FCC ID, Type, and IC ID). This will help look up documents in their technical specifications to confirm two models or more, if they exist.
It seems weird that Motorola would issue a XT926 just for a CDMA and only ONE XT925 number for multiple models (some of which do run CDMA)? It doesn't make sense from a business perspective either. Why produce many different GSM models, when you can produce one and alter the firmware (if for example it doesn't sell in Australia, flash a new ROM, repackage it, and ship it to Canada).
Just my two cents. If you have any of that info, PM me. I'd love to look into it.

Sir- I want to point out that wataniya is not the provider for the LTE in Kuwait. I had I different SIM card when I took the screenshots. In fact it’s a US AT&T sim that roaming on Wataniya Telcom in Kuwait. The LTE provider in question is Zain Kuwait https://www.kw.zain.com/kw/af/home.do?lang=en . plus I have tried the Telestra firmware and used the correct APN for zain; the same APN I used on the iPhone 5 and the USB dongle. To add, I tried using the LTE/GSM/WCDMA, LTE/WCDMA, and LTE alone options and had it at automatic (2G/3G/4G When I set it at only LTE I lose single completely. The other options allow me 3G H+ only.
UserDemos makes a lot of sense! There are only two modles out there. The 926 and 925. I believed that 925 can run on LTE 700 / 800 / 1700 / 1800 / 2600 as advertised by Moto. She I don’t know where the problem is? Anyways the info as showen in the back of the phone are Model XT925 FCCID: IHDT56NG9 TYPE:M0D46 IC ID:109O-T56NG9 . and the BIG CE number is CE0168.
Thanks for not giving up :good:
Yes I confirmed that you bought the wrong phone.
This what happened to me. I'm in Etisalat 4G, so if you want razr hd with enabled 4G lte you should buy it from Australia or UK.
I recommend Clove or Handtec the release date after 2 days.

Were able to figure this mastery out?
In many cases such as Milestone, Milestone 2 etc. there was a Canada / Latin American version and Europe / Asia version with different 3G bands - yet, the phone was called the same for all these versions (MS1 -> A853). Verizon's CDMA Droid (A855) was called differently and other CDMA carriers also had different name (such as MS A854).
This is the same thing, only about 4G bands.
There are 3 version of Razr Hd
XT926 for Verizon
XT925 for Canada, 4G band 700/1700/2100
XT925 for UK & Australia 4G bands 800/1800/2600

XT925 for EUROPE & Australia 4G bands 800/1800/2600 ( and some LATAM country) ( Have Dual Channel HSPA up TO 42 mbits )
Is just not a baseband problem like many people say ... if the hardware don't support ... the hardware don't support ! Yes some phone have hidden band ! but not the case in the moto hd
I confirm again and again...

if you want DC HSPA because no LTE ... buy the Europe Asia Version ... ( My carrier telus in canada have great DC HSPA coverage and speed are great near 25 mbits in download - i have sold my rogers version for the europeen version ... i never get LTE but my baterry is really good ... and have DC hspa in many many place )
if you want LTE choose the right phone before buying...
and oh yes ... the Motorola phone from U.S ... you can't unlock the bootloader !
and again don't listen people who claim is the same phone and this is just a baseband file problem !
motorola brazil razr hd has 2600mhz band.
I have one and all carriers here use this band...
