so can anyone tell me if I am right? Here in north america we are just starting to get UMTS in some areas. And I have been waiting for the universal wanting to get one. but our north american umts network is on the 1900 mhz band mode and the rest of the world uses the 2100 mhz band mode for umts. that meens that the universal will have its umts radio on 2100. So does that meen it wont work here as a umts device and I will be stuck with just gprs?? if so I just cant buy it
Hi,
AFAIK, all UMTS phones, so the Universal, are GPS phones as well. So, form a technical point of view you can use the phone whereever there is reception. At least here in germany,the GPS service provider are the same as the UMTS service provider. So, if you leave a UMTS zone the phone automatically logs into the GPS zone. I would expect that it is the same in the US.

EDIT: Now I have read your message completely and see, that I provided an answer that does not match your question 2nd try: I would expect that if you get your UMTS device via an US provider that it matches its UMTS band. But, without coverage you are stuck with GPRS/GPS, thats right
ARGH, that sucks. because Im sure that by the time they make a north american universal it will be outdated anyway :roll:
I tend to agree. I thought that with UMTS whis crazy frequency problem would disappear finally....
I just checked on the german t-mobile page, which has the Universal, T-Mobile MDA Pro as they call it, on their page.
Unfortunately there is no UMTS frequency mentioned. Maybe there is one generic UMTS setting which allows different frequencies to be used, and all UMTS devices support all the frequencies?
OK, that might be a bit optimistic, I agree ...
Edit:
I got interested and checked for the UMTS frequency situation: http://en.wikipedia.org/wiki/UMTS
So, even with the special US situation, the UMTS frequencies are not connected to contries but comminucation methods (FDD, TDD). So, as long as the UMTS implementation in the US does not differ from the ITU standards, you should be able to use the Universal in the US. But even the above mentioned wiki page is not clear on the situation, so probably you will have to wait and see ...
Oh well I guess I will just have to wait for the wizard or maybee even (Forgive me) a non htc device???
if the wizard has a slower prosesor than my magician I just cant buy it either. and I have my magician tweaked up to 520mhz
I know this is off-topic
I have my magician tweaked up to 520mhz

what program are you using for that...??
I tried PHM and it hang :evil:
then I tried XCPUScalar.. and it worked, I could overclock it to 520 MHz, but when I tried Beta-Player to benchmark the device.... it said 416 MHz..
and when I used lower speeds.. Beta-player and the XCPUScalar gave the same result
so I could only under-clock my device, but I couldn't overclock it...
are you sure that your device is running at 520 MHz?? and if so, is it stable??and any noticeable improvement in performance??
thanks in advance
Heres the deal my friends in the US.
And btw....its really not good news at all....

Hello,
I'm curious to know is the 3G HSPA 2100/1700 frequency hardware based or software?
For example can one change the frequency to point say at 850MHz?
I'm currently with Rogers, and their 3G network is not on the same band.
Thanks
Nah, its a hardware restriction. Tmobile did this because 2100-1700 are dedicated 3G pipelines. They device does not have 850 or 1900 wcdma only 21-1700
http://www.phonescoop.com/phones/phone.php?p=1763
this is so it can not be used on at&t 3g.
if i remember correctly 1700 is for d/l and 2100 is for u/l
i dont know much about phones....or the various cellphone network types.
But isn't a frequency a frequency? Wouldn't it be the softwares job to interpret the data on the various frequencies?

True, software could interprete the singnal, it just wouldn't be as efficient.
The easiest comparison I could make would be video enconding on a PC. You can have your PC encode a video in h.264 it will just take a while. Meanwhile your HD-DVR is doing the same thing in real time. The difference is the dedicated chip in the HD-DVR that only does h.264 encoding.
I have no idea if there's a way to get the raw signal from one of the other radios, let alone if there's enough power in the G1 to interpret it without the chip. I'd guess not on both cases.

Nice comparison... but I think it is more like a wireless router. A 802.11b router can't use 802.11g... why not they run on the same frequency? Because it isn't just the frequency you have to look at. G takes a different amount of power than B. Same with the different bands. 2100 take a different amount than 850.
If you really want to see a comparison wiki radio frequencies and you will see why cb radios and those little walkie talkies don't work on all frequencies too. There is a lot more to it than just telling the radio to go up or down a couple numbers.
Nope
Qualcomm 7201 Chipset and Baseband is fully Compatible with 850 / 1700 / 2100 / 1900 Bands
You just have to have additional Component on the Board to have additional Support
Please see the motherboard Diagram its Self Sufficient i think.

I thought it was GSM 850 / GSM 900 / GSM 1800 / GSM 1900 WCDMA 1700 / WCDMA 2100
Is GSM 850 the same as WCDMA 850?
But it looks like you answered two questions with that post... someone else was looking for pics of the phones insides. Good job finding those.
Its all hardware based and will not work on at&t 3G. The phone does not have the hardware to pick up 850/1900mhz frequency. Tmobile did this not to screw people over but because they have no need to. The phone was made for T-mobile there is no reason to support at&t bands.
Just like everyone said, it is a hardware thing. As far as I know, since T-Mobile got the short straw and got the 1700MHz band, there really isn't a "universal" phone now that can operate on all GSM and all 3G frequencies worldwide yet. Manufacturers would have to have like 9 total bands supported and with the trend towards smaller and smaller phones, it's something that gets cut early. So the short of it is this: expecting the G1 to work on AT&T's 3G band is a lot like expecting an FM-only radio to pick up AM signals.....or exactly like expecting an American FM radio to pick up all the FM stations in Japan (which uses a wider FM band.)
But keep in mind that the 1700/2100 numbers don't refer to a specific frequency, but a band of frequencies at or around the number. If you've ever used a shortwave radio, you know that they use terms like "the 11-meter band," which is a range of frequencies with a wavelength of around 11m. Luckily, the range of the 2100MHz band that T-Mobile USA uses overlaps the European band enough to make the phone work over there.
Doesn't the tilt do 1700?

If I'm not mistaken, the Tilt was released before the 1700MHz band was a reality.

Something Interesting...
I found something that might be of interest... If you install "Any Cut" and create a link for "Phone Info" (Long press on you desktop, then > Shortcut > Any Cut > Activity> Phone Info). Once created, you will have a shortcut on your desktop for "Phone Info". Click the "Phone Info" Shortcut and press the menu key. Then click the menu option "Select radio b..." From here you will have the option to change your radio band:
Set GSM/UMTS band:
Automatic
EURO Band
USA Band
Japan Band
AUS Band
AUS2 Band
This would suggest to me that the radio can be controlled via software. What do the experts think? Do you think we could get 3G working on AT&T's Network?

My phone is locked. I can't use my AT&T SIM. Sorry. But when I switch to different bands, I do loose my signal until I switch back.
I have a friend who builds small electronic devices. If I had a damaged tilt would it be possible to remove the 3G antenna and a few resistors and replace the ones in the G1 to make it work on the ATT 3G bands?
Does anyone know enough about the board construction to know what would need to be replaced?
I did use that activity to change the band to get it to work with my provider here in the United Arab Emirates. The thing is I honestly don't know what they are using, publishing reliable info is not a strong point of the operators around here. I grabbed that of a web-site:
The Middle East operators are using the primary 2.1 GHz band for the UMTS/HSDPA operation. Not too precise eh.
I used the Japan labeled band.(?)
sim unlock GI via 611
I was on the horn with CS anyway and figured it would be worth a try to ask for an unlock code request for my G1, they dont have the magic keygens at the Tmob secret base, they have to request it from the OEM, back in the day they gave them out but after many public keygens they got a bit pickier about who get the keys to the liquor cabnet.
when mine comes Ill get an at&T prepay bump sim and mess about a bit just to prove it wont work, and to everybody else ...CALL 611!! ask them for the unlock code tell um you go back and forth to Europe or Iraq or Pagopago, I may not be necessarry but I always have a bit of fun with the story, it used to be a email system send imei to "[email protected]" and get your code in a few days, the good ole dayz

The Menu is shown as the Chipset Qualcomm 7201 actually supports These Bands, But it Require Radio RF/TS Unit to Actually Push Radio Frequcny via Internal antenna. Seeing the Board Picture it only have 1700 and 2100 RF Units. So even is Chipset is compatible it can not Push the Signal or Received Signal other then it is made for. I think in Future then can alter some Hardware and make it more compatible.
So, I'm wondering if I had a broken tilt with the 850 transmit antenna chip in it if I could have that antenna module removed and put in the G1 would that be all that is needed to work on the ATT 3G network?
Anybody, know if that might work since the chipset seems to support the frequency?
I can't afford to pay more than $175 for my phone. I'm a long time ATT customer and can't/won't change carriers. So, I'm trying to get one off of Craigslist or Ebay for about $250.00 or $275.00.
If anyone knows where I can get one for that price please let me know. If I can get one I'll try the antenna replacement idea.
Hi all
I just got this phone for use in Italy, and am now waiting for my unlock code to come through.
Meanwhile, and as the main question, I wonder if it ever will be a way to turn on the WCDMA 900 band that we use here (along with WCDMA 2100), since it's not supported out of the box, being an American phone.
I would like it to be a 900/2100 phone, instead of 850/1900/2100.
I'm sure the phone supports it (being much newer than my current Motorola Defy that's able to do it), it just has to be unlocked somewhere.
Any info is appreciated!
Thank you

Sorry, but that is not possible as the hardware does not have those radio antennas in the phone. This is ONLY a GSM/HSDPA+ phone not a WCDMA phone. There is not a way to change that since it is a hardware antenna change.

As far as i know (pretty sure on this), all 3/3.5G is WCDMA. HSDPA(+) is WCDMA. WCDMA is just the name of a RF modulation, and 850, 900, 1900, 2100 are just the bands the protocol can run on.
In fact my question could just be translated to: as these settings are stored in the baseband rom, we need to flash an alternative baseband to enable those, or discover where they are set.
I guess a motorola phone similar enough to the A2 (i.e. same.hardware) should suffice as a "donor" phone for the baseband rom. May be an ipothetic european A2 of the future.
Has a phone like this been found yet?

The hardware on A2 does not support this, the antenna is not setup to capture these frequencies. Just because the baseband is in the rom does not mean that you can change the hardware.... Yes technically all 3G boils down to WCDMA or CDMA technology, but there are major operating differences between even the different spectrum in them. The issue you have is that the phone is not going to be able to capture those on the hardware layer. It is similar to trying to get am radio signals on an FM radio, with an FM antenna.
Well I hope you are wrong
I think (hope) motorola has put an universal antenna on the atrix 2, it'd be anti economic to do otherwise.
BTW, 850, 900 the antenna differences surely are minimal.
It sounds more like as a RF chipset limitation on the simultaneous bands used... like three of em. "Tri-band umts".
As with the good old gsm phones marketed as tri- or quad-band, like my v525, the actual bands used were depending on where you lived.
All of this, i hope...
Did you buy an MB865, or an ME865, as they have two totally different antennas. mostly we discuss the MB865 in here.... and I can tell you that there is no way to change the MB865, because it setup that way on purpose, and locked to AT&T's signals via the antenna and wireless chipset, by Motorola. The ME865 might be a better choice I think there are two versions of that one, one is the Chinese version and the other is more international.
ME865 it's for asia only. Motorola phones found over here follow the MB nomenclature. I have got an at&t MB865.
Anyway if a €300 phone (defy) can do that, I don't see why motorola would have chosen to spare on a $ .5 part on a €550 phone (euro price tag estimation), and have to redo a whole new pcb layout if the MB865 ever comes to the old world. Even taking into account the at&t exclusivity. It's anti economic for them.
Btw I don't want to be right at all cost, please don't misunderstand my words. ;-)
Also if you look at pdadb you will find two.models, mb865 and mb865a.
I don't know if they're both real or not, but they are identical specs-wise the only exception being the lack of wcdma900 band on the "a" version.
If such version actually comes to market, i guess a baseband transplantation could be done...
Dear All,
I recently got this device in Hong Kong and is hapi with its performance!
But I am still wondering if this device could actually use the LTE available in HK?
I knw the msm8960 claimed to be capable of utilizing all frequency of radio,
so is it possible that there is some soft lock in the baseband?
Could i flash the baseband or replace the modem driver from other device to access other frequency?
any idea is appreciated!
Thanks!

I think it has to modifiy the ROm and the hardware
I tried to figure out, if our Photon Q is supporting more LTE bands than 1900 MHz (#2 or/and #25).
-> http://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths
On some sites there are reports for having another band. (Have to search again, I think it was 850 MHz, #26 or 700 MHz, #12/#17/#29.)
I have also searched for supported frequencies for MSM8960.
I found some BlackBerry devices based on that SoC and 2 different versions of supported LTE bands.
One version (UK) supported 4 in europe used bands und the other version (US) supported 4 in US/Canada used bands.
I think that the Photon Q is like the BlackBerry US version and supports 4 LTE bands in US/Canada.
If you need a few sites, I will search again and show it to you.
The strange thing is, if I set to LTE only (via 4636) I can see all 4 carrier (germany).
We have 3 bands with LTE on it, but I can only get signal to max 2 of them.
Band 3, 7 and 20 (1800, 2600, 800 MHz).
The weird thing is, that on band #20 (800 MHz) only 3 carrier are active, so it has to be band #3 or #7.
Maybe I'm missinterpreting things and thats just a sideeffect of crossing bands of LTE US and UMTS Germany.
On stock ROM there was another "secret phone code" to see what the phone-part is doing. (From qualcomm I believe.)
I think I will test it some other day, to see which band is active.
At last, I was never been able to "login" or "register" into my carriers network within LTE.
Please discuss about that possibility, I really want to find out, which frequencies are supported by our phone on LTE.

Dear Loader009,
Thanks for your information! I'm really impressed that you could actually search the carrier in 'LTE only from Germany!
Could you please share the version of ROM you are using?
And if possible, any screenshot? I really want it can be used in HK with LTE(1800, 2100 & 2600Mhz)
Also do you have more information about the secret phone code? I think it would be interesting
Actually, I noted that xt925 and xt905 are using the same chip MSM8960 with LTE usable in HK.
Is there anyone can locate the radio/baseband of their rom and port it for XT897?
I am willing to try it with my machine.
If this work, I think we could use this photon q all over the world!
Any idea?
Regards,
Vasco

Of course, I was just blind guessing the hardware for xt926 and xt907 are using the same hardware.
If not, there should be one chip controlling the modem channel of the device to be replaced.
But WHICH ONE???
Any expert in this area can solve this question? I am a dummy for radio stuffs
This seems like it's getting pretty interesting.

Dear all,
I'm also very interested in this topic since I imported a Photon Q to Germany and was wondering if it's possible to use the local LTE 800/1800/2600 bands.
I think the first thing we have to find out is whether the hardware is capable of using other bands than the 1900 band listed on the Motorola website. As Loader009 states he could see LTE carriers which are known to use different bands I assume the hardware can do it. Otherwise the carriers wouldn't have been listed, right? Maybe someone from another country with different frequency bands can check and confirm that he can see those carriers as well?
Thus, the limitation to the 1900 band should be software-made and could be modified by a developer. I hope someone can participate at that point as I don't know much about coding...
I'm using CM10.1.
I can't remember the secret phone code, I have to do research again.
This secret phone code only works on Stock ROM. (I stupidly deleted it, when it wasn't working on CM10 anymore.)
The one secret phone code I used to force "LTE only" was *#*#4636#*#*.
Please DON'T change the baseband (don't even tap on it).
This can do problems to you. (I had to use QPST to recover the supported frequencies.)
Also, developers (afaik) can't modify the modem firmware.
We also don't even know, which LTE bands the Photon Q is capable of. (Except 1900 MHz)
I've got my 32GB SDCard back and will test it in the next few days out.
I hope I'll find that secret phone code, I'll also make a few screenshots.
Got the code!
##33284# <- ##DEBUG#
It only works on stock afair!
I'll test tomorrow, it's about 3am now >.<

I have read the "QU_SnapdragonS4_White_Paper_FNL_Rev6.pdf" and found there following entry:
-----------------------------------------------------------
• Industry’s first fully integrated 3G/4G world/multimode LTE Modem: <<<Supports all of the world’s leading 2G, 3G and 4G LTE standards>>>.
It also includes integrated support for multiple satellite position networks (GPS and GLONASS) as well as short range radios via Bluetooth,
WiFi, FM and NFC.
• Designed for speed, compatibility and power savings:
Snapdragon S4 Processor MSM8960 chipset includes the industry’s only complete platform that integrates all of the world’s leading 2G, 3G and 4G mobile broadband modem technologies on a single chip. This new integrated multimode modem is based on an advanced, programmable architecture that is performance, size and power optimized for the fastest combination of modems available for:
- LTE FDD/TDD (Cat3)
- 3G (DC-HSPA+ Cat 24)
- EV-DO Rev. B
- 1x Advanced
- TD-SCDMA
- GSM/GPRS/EDGE NFC.
Multimode/Multiband Means Worldwide Coverage.
• Support for multiple radio frequencies: Mobile broadband technologies are growing increasingly complex in their implementation. LTE is currently being implemented in over 40 diff erent radio frequency bands throughout the world. To complement its wide range of modem standards supported, Qualcomm has designed the Snapdragon S4 Processor MSM8960 CHIPSET platform to <<< address all commonly-used frequencies (from 700–2600 MHz) and bandwidths up to 20 MHz>>>, allowing its customers to address any mobile network opportunity whether the simplest single frequency implementation to the most extensive multi-frequency global mode, whether 4G, 3G or 2G.
-----------------------------------------------------------
Based on the document the chip can handle all LTE Standards, but it depends on his "advanced, programmable architecture"....as written there and how Motorola / Sprint implemented this, maybe they reduced LTE only to one Standard.
I don't have LTE in my area and so I cannot test this.
That's possibly right.
Something else:
If I remember correctly, somewhere in this forum have been said that for CDMA the internal Sprint "ID"(?) is used.
Maybe that's also the reason why I cannot connect to LTE in my area.
The phone is trying to "login" with the Sprint ID and this of course won't work.
The ##DEBUG# menu wasn't helpfull. It shows frequencies for american standards and not for GSM/WCDMA.
Also the LTE menu is also not very helpfull, it doesn't show frequencies at all.
Any News on this topic?
Maybe one of the developers can give a statement?
Yesterday I tested a LTE compatible SIM card.
My Bro has a Samsung Galaxy S4 with 4G/LTE in my area.
So I've put his SIM-Card into my Photon Q and set LTE only.
I had no luck, the Phone couldn't register into the network for this SIM.
I guess either it has the wrong frequencies or LTE is for inbuilt "SIM" (Sprint SIM?) only.
The latter. LTE is configured only for 1900 MHz which Sprint uses.
LTE is configured only for Sprint's frequencies, however, it supports the United States frequencies of PCS blocks A-G. The G Block is Sprint's current LTE channel, and they may deploy it later on Blocks A through F, depending on if they own the spectrum in a given market. The reason you see EU networks when the phone is in LTE Only Mode is most likely because the Phone still sees GSM signals, but will only connect to LTE ones from those GSM signals. Likewise, in the US, if you force LTE Only and then search for networks, AT&T and T-Mobile US will come up as the GSM carriers the Photon Q sees, rather than the LTE signals it sees.
Setting the Photon to LTE Only will not do anything for LTE in the EU. I suspect that if another carrier in the EU uses the 1900 MHz for LTE, the Photon Q will have no issues connecting to LTE in Europe. But until that time, be happy with HSPA.

Can this configuration theoretically be changed / other frequencies be added?
Only if you break BP security.

Sorry, what's that?
IIRC The only place with 850mhz LTE available is the Chicago market and currently no phones at all support it. :crying:
Not only does your phone need to support it, your PRL and cell-site does too...
Screw my bad luck i didnt know about the band stuff when i ordered my phone and i got 1700 AWS (US Global GSM) which doesn't work for 3G in my area, I cant get Global GSM, is there any way to make 2100 GHz frequency work on US GSM?
Even if it may require some hardware modding or some external support, I would really be wanting to run 3G on my phone because it's really an affordable stuff in a small range..
Any help would be supported.
Thanks
