[Q] 2100/1700 AWS band problem - Moto G Q&A, Help & Troubleshooting

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

[Q] Anyone using the Omnia 7 in the US on AT&T

Is anyone using the Samsung Omnia 7 on AT&T? I know it has support for AT&T's 1900 band for 3G but wanted to know how the experience is. I'm in Germany this week and was hoping to see if I can pick one up [not really happy with any of the AT&T phones].
Also, with updates possibly being controlled by carriers what's the workaround for buying an unlocked device from overseas and using it in the US on AT&T?
Thx!
can't tell you about omnia on at&t, but as far as i'm aware if your phone is unlocked from carrier, i don't see any reason/possibility for them to delay an update being rolled to your phone.
Cool, thx.
You should be able to get updates via the Zune software.
I'm sorry. this is my first post for this forum. Im not educated on on the compatibility of the EU phones on US carriers....
But is this really possible? I really like the SS Omnia the best so far.
an unlocked ominia will work perfectly fine on AT&T?
it will work perfectly.. except for the lack of 3G. The omnia lacks the all important 850 band at&t uses... and the 1700 band tmobile uses.
An explanation for "The omnia lacks the all important 850 band at&t uses" would be useful as AT&T also supports 3G on the 1900 band that the Omnia 7 supports. So seems like it should work...

Dependa on the tower. Lacking tje 850 band is a big deal on att.

Thanks for that response. I really wanted to see if I could sneak away with the omnia as the focus isn't really as good

One advantage with the Focus is it has an SD card slot to extend storage.
If you use you phone for music,movies and games it's a big +.

lacking 850 is not a problem since only mayor citied like new york, san fran, dallas etc. have 850 and the majority of normal city only have 1900. so 1900 is fine given you don't have access to hsdpa and hsupa, only regular 3g. now if only i can find an unlock omnia 7 under $650.

There are maps available showing coverage for each AT&T 3G frequency band. I wouldn't dismiss one band over the other. It all depends on what city you live in.
Check into the coverage areas before you waste money on a phone that won't give you 3G coverage in your area.
Very interesting as I googled AT&T 850 vs. 1900 MHz Coverage and pulled up a very interesting map [can't post a link due to my post count].
Coverage of the two bands is almost identical. I didn't know that speed is something to give up on the 1900 band though.
Good info. Yeah, I'm in Europe this week and no one is offering it unlocked!
here's the maps.
http://www.cellularmaps.com/att_850_1900.shtml
my question would be though, which is the band they are going to expand going forward???
so what's the difference between these bands? the phone does both so you would be "covered" so to speak

I'll be asking at an AT&T store, perhaps they can shed some light...
i personally am not sure if all phones handle the varying bands straight from the OEMs. HTC lists what bands their phone supports to each region, but in saying that it would be good to know what would happen if you got a omnia to the US (or in my case if i somehow managed to get an unlocked focus to australia ).

I don't think the phone supports at&t's 850mhz band.
according to this it does
http://www.pdadb.net/index.php?m=pd...icially_confirmed_windows_phone_7_smartphones
and this
http://www.gsmarena.com/samsung_i8700_omnia_7-3537.php
GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS1900, UMTS2100
CSD, GPRS, EDGE, UMTS, HSDPA, HSUPA
From what i've heard, ATT doesn't even really use the 850 spectrum much anymore...
Several people are selling this new on eBay for ~$600, but it does not support 3G. As per the one auction details:
* Works with AT&T and T-mobile EDGE but does not work with 3G networks in the USA
* Works with AT&T 1900Mhz 3G but not AT&T 850mhz 3G - Does not work with T-mobile 3G in the USA
I love the design of this phone too but is it worth paying all that money for a phone where you won't be able to take advantage of all its features? Edge is slow as Sh*t compared to 3g in my area. Just consider that if you really want this phone in the US.

[Q] Is the international HTC One S version compatible with any carrier's 3g speeds?

I have both the T-Mobile and the international unlocked version. I have the latter because, in my excitement, I didn't take care to find out if it will work on T-Mobile's 3G speeds. To my dismay, it doesn't, and I have an extra phone.
I'm wondering if it will work on any other carrier's 3G/4G data speeds. Searching forums and support threads haven't gotten me any answers. Any help at all would be appreciated.
I bought mine in Britain and am using it quite happily here in Japan. T-Mobile USA has a relatively rare frequency band internationally; I think as long as you have 2100MHz and 900MHz bands, which this phone has, there should be an operator in almost every country that the phone will work on. In fact, it should work on most operators in most countries.
The phone has 850/900/2100 MHz bands for 3G; T-Mobile runs "4G" (actually 3G) on 1700/2100 aka AWS - this requires BOTH bands to be present in the phone, which is why the One S doesn't work. T-Mo USA also has 1900MHz, again not present in the One S. Can you get EDGE 2G data, which should be possible on 850MHz?
In the USA, it should work on AT&T, as they use 850MHz for 3G. Maybe you can find someone who will lend you a SIM to check it.
In Europe & Asia, it should generally work no problem.

Any chance to enable all LTE frequency supported by MSM8960?

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.

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...

Investigation: The mysterious 850 MHz band

I want to figure this out once and for all.
What services does this phone support on the 850 MHz band?
The big question is whether UMTS/HSPA works. NYC area has amazing 850 band coverage on AT&T.
If I were to put a prepaid AT&T SIM in my phone, set my phone to only operate on the 850 MHz band, and set the proper APNs (necessary for 3G?); would I be able to get data beyond EDGE?
Only one way to find out...
There's no mystery to it if you read through the [GUIDE] Set up Verizon Galaxy S3 as World GSM Phone (confirmed working) thread and the [BOUNTY] ($205 so far) Enable HSPA+ on 1900 MHz / 1700MHz for VZW Galaxy S3 i535 threads completely....
With the radio software verizon has on the phone, the galaxy s3 is quad band GSM (850/900/1800/1900) and single band WCDMA (2100).
We don't know if it has the hardware for WCDMA 850/900/1900 and until now, nobody has successfully flashed a different radio due to the bootloader lock. Keep an eye on the "enable WCDMA 1700/1900" thread for updates.
And just to answer another question that you might have, when my S3 was rooted and set up to work in Germany, I tried both T-Mobile and AT&T sim cards here in town. The problem with the S3 is that even if you try to select a different WCDMA band in the field test menu, the radio firmware will not allow you to change it from 2100. So in an area with T-Mobile PCS (1900) and AT&T PCS/CELLULAR (1900/850) WCDMA, each test I tried only ran on EDGE.

Wow... That really sucks.
So, there's literally no way to get 3G outside of Verizon aside from MetroPCS EVDO?

The first step is to experiment with different radio files, as one user in the 1700/1900 thread wants to do, but we need to get the secure-boot/bootloader unlocked so those files can be written.
Phones like the Rezound had the hardware for Quad-band WCDMA (3g), but took a radio file flash to make it work. The reason there is a bounty is because we -think- the Verizon S3 has the hardware, it will just take some work to get the software on the phone to talk to that hardware.
I know. I've been following the thread.
Was a little unsure of the details regarding frequencies.
As far as I understand, they're at a dead end. They need JTAG/UART to continue without worrying about bricks.

Yeah, and sadly, I lack the skills and the bounty probably isn't enough to attract a dev with JTAG and a phone to fiddle with to solve our issue
Verizon cdma is ran by nortel dual urban base stations the frequencies are 810-910 and 1840-2000mhz. The LTE is 690-760mhz 1x means that your on 850. 3g means your on 1900 or 850 depending on how far away from the site you are, and 4g means your on LTE. The LTE base station is ericsson but speeds will vary depending on whether or not the site is on fiber or T1 transport. Normally they keep the pre pay customers on the nortel dual urban... Oh by the way we are starting to decommission the lucent cdma on metro pcs sites and convert them to t-mobile GSM but luckily metro uses ericsson for LTE too so there's hope.

Bad ESN Verizon One hd in Canada?

LOL I'm an idiot, was thinking HTC ONE when I said one hd...
Found a really good deal ($170) on a bnib razr hd from verizon with a bad esn on ebay. Didnt really have the time to fully research it before the auction ended so I just took the chance and placed the order.
Did some searching after the fact and have found some really conflicting information. I know the phone would be pretty much useless in the states, but I'm unsure of its usability in Canada? I've herd they would work fine in asia and india so I'm basically curious if anyone knows the extent of how far verizon shares its blocked phone information? Does it extend to Canada?
I've herd on the states you need to have your phone activated onto a network? In Canada we just throw in our sim card and are good to go. Is this a different technology (CDMA vs GSM?). If so assuming the Activation portion of the phone is blocked could the sim card part of it still be open theoretically?
Assuming its possible to work with the bad esn does anyone know if I could use LTE on Bell/virgin?
According to bell it uses LTE AWS 1700mhz and LTE 700mhz and HSPA 850mhz and 1900mhz
According to gsm arena the xt926 uses:
HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 700 MHz Class 13
Should be fully compatible no? I cant find any information on what class bell uses for their LTE, nor do I know if the class affects anything?

You can unlock it for gsm carriers in the us and its already unlocked for international use. I know with att u get h+ witch is good enough for me on straight talk. I average about 6mps.
Got the phone on the weekend. It works fine on bell/ virgin except I can't connect to lte. Does anyone know of it's possible to unlock lte? According to gsm area the phone should be compatible with lte 700mhz which is what bell uses... Will that radio com thing you guys use to unlock it for us carriers help?
