[Q] ATT Atrix 4G and UMTS 900? - Atrix 4G Q&A, Help & Troubleshooting

I just want to clarify something... I read another thread (http://forum.xda-developers.com/showthread.php?t=991912) that suggests that you can enable UMTS 900mhz on an ATT Atrix (though the specification over at Motorola says it doesn't have it).
Can I just get a confirmation that I can or cannot turn on UMTS 900 on the Atrix (be it by flashing a radio version)
Running a stock but rooted ATT MB860 Atrix 4G with baseband version N_01.7.30P...

Bump... why do I have to keep doing this?

[Q] No 3G network on HD2 using 2.2 Froyo Cyanogen mod 6

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.

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

Is there any way to activate the 1700 MHz band on the I9100?

My phone is from France and I'm trying to use it in the US but 3G isn't working.
I've already rooted it and installed a custom rom.
Anyone got any ideas?
Thanks!
Not possible. The hardware doesn't support 1700. Switch to AT&T.

3G will not work with T-Mobile. You either need to switch to AT&T or return the phone.

[Q] Atrix 4G from at&t running in 900mhz (brazil), possible?

Hello!
Here in Brazil motorola sell the atrix (non "4g") the only difference I have found is the support for 900mhz in 3G. The atrix 4g dnt support 900mhz in 3G.
My question is: its a hardware restriction or only software, I can unlock the 900mhz frequency for 3G network in ATRIX 4G AT&T or its impossible?
thanks!!

[Q] Different Radios? UMTS 900 interested

If there's any different radios for MoPho?
I wanna get UMTS 900 working on Photon. I know that it's not listed in the specs, but so as for Atrix 4G, and guy here flashed another radio and got UMTS working.
So, if there's any info about MoPho?
Where i can get stock radio, so i can try another one?
If Atrix 4G's radio will work for Photon? (I suggest hardware is pretty the same).
Any input on this is appreciated.

from what im seeing here
-----The phone operates at frequencies of CDMA 800 / 1900 / GSM 850 / 900 / 1800 / 1900 / CDMA2000 1xEV-DO Mhz. -----
i would think it would work does it not work for you? , the photon community is still working hard on getting everything unlocked fully and right now what seems to be the main focus for the dev community is getting roms and wimax to work on an unlocked bootloader,
OK. first of all i'm personally not interested in CDMA part.
It operates
GSM 850 / 900 / 1800 / 1900
UMTS(WCDMA as i understand) 850 / 1900 / 2100
Local operator uses UMTS 900. So EDGE only for me. And i got H+ icon with another operator.
But i suggest the only difference is the radio flashed in the phone.
One user on XDA reported that he get UMTS 900 working on hit Atrix 4G. (Atrix got the same freqs listed as Photon, without UMTS 900).

so far as i know they havent gotten a full unlock of the frequencies they use and since the photon is really sprint only here in the states, it makes it hard to jump from one band to another since no one really has it, i know that in japan they had a wimax photon, that one might be a shot i just have no clue where to find a sbf file for it nor whether or not it would even flash to the sprint photon, are you out of the US and if so which provider?
There's a topic with leaked sbf that says wimax working. not sure if it's from japan.
I cannot find any radio in .zip or .sbf file. If i could find one, even stock radio, I could try flashing one from Atrix. Dunno if it help or not, but why not to try?
Yep, I'm out of US, in Kazachstan.
Beeline and Tele2. Second one require UMTS 900.

talk with joker or shabby they should know where its at, im not that far into developing as they are, im just trying to learn as i go
This is definitely something i would like to see happen in the future. Im moving to Sydney at the end of this month and plan to take trips frequently to area that only have dual band coverage on Optus (UMTS900/2100). So until someone hacks this i will only have 3G in Sydney where they have HSDPA2100Mhz.

Flash AT&T Radio on INTL Atrix?

What happens when you actually flash a AT&T .91 Radio over a N_01.100.00R?
it unlock the capability for HSPA+? Better Battery Consumption? All Answers are welcome
All i know is that the Atrix 4G is 3 Bands for 3G connectivity HSPA+ and uses the Qualcomm MDM6200 chip
and the international, HKTW Atrix are 4 Bands but only HSDPA, is the same chip on all atrix in the world? or they are different with the USA version?
Sorry for my bad english if i wrote wrong something
Regards
the short answer is no
sent from my Atrix via XDA premium
