Can anyone confirm if the ATT Atrix 4G supports tri-band 3g 850/1900/2100?
GSM arena states it supports all three frequencies
http://www.gsmarena.com/motorola_atrix_4g-3708.php
But both amazon and walmart list the 3g bands to only support 850/1900
I'm currently in hong kong and the primary 3g band is 2100 so this will definitely affect my decision to buy the phone outright.
anyone with the atrix overseas with input would also be greatly appreciated!
Thanks for your help!
Go to www motorola dot com/atrix there is tech specs it supports 2100.
It doesn't support 1700 though which is critical to functioning correctly on TMO's network....
Too bad, tmobile's 4g is much more widespread and reliable than AT&T. It's sad that from a 4G/data perspective, AT&T is by far the worst carrier.
Ok what to make of this? Will this run on CDMA or not? Is CDMA synonymous with LTE?

Quote: The Galaxy S2 will run on 4G/LTE networks on HSDPA and HSUPA in a quad band configuration under GSM or dual band under WCDMA.
I can't speak to whether or not it will run LTE as I don't know how Verizon does this or for 4G for that matter as I don't know much about how that works... but the international version (only one available to north america by ordering from abroad) is NOT CDMA. It requires a SIM for it to work, CDMA is non-SIM
Edit: If I am wrong don't crucify me it's just my crude understanding
Its the way I understand it too but the dude has the phone in his hands. Granted, this doesn't make him an expert but it makes me wonder.

The SGSII version that has been announced is a GSM based phone meaning no CDMA.

CDMA does not mean LTE. This is not a LTE phone as it doesn't have the LTE bands to support it.

They probably meant there will be different versions of the phone. One version with quad band GSM (UK version about to be released) and dual band CDMA version that might come out in the future.
That being said, the SGSII uses HSPA+ 21Mbps speeds. Bell Mobility in Canada labels 4G with HSPA+ up to 21-42 Mbps. Check with your carrier for their network speeds. Carriers label HSPA+ with 4G to attract more customers but this is really not 4G, HSPA+ it is an evolution of 3G (basically higher speeds).
Hope that makes sense...
It does make sense. I just wish they'd announce that it's coming to verizon with lte capabilities already. Even if they said it'd be a year, at least I'd know. Thanks for the inputs.
yeah bell is stupid like that... in reality it's more like 3G+ or 3.5G
A number of tablet manufacturers are now offering 3G capable tablets. However, trying to get the tablet to work in 3G mode can be a frustrating experience to say the least.
Here in the USA there are four primary players in the mobile networks arena, AT&T, T-Mobile, Verizon and Sprint. AT&T and T-Mobile operate WCDMA Band Networks, while Sprint and Verizon operate CDMA Band Networks.
From what I have seen thus far here in the USA the typical tablet with an internal 3G radio operates using the WCDMA band frequencys. If I use my PiPo M8pro 3G tablet as an example only, the printed M8 User Manual specifications are outlined as follows:
HSPA/WCDMA: 2100/900MHz
GSM/GPRS/EDGE Quad band: 850/900/1800/1900
Download maximum 7.2Mbit/s
Upload maximum: 5.76Mbit/s
All this simply means that the tablets are supposed to be totally suitable for use on an international basis. However, as they say, "There is a fly in the ointment".
First, in the USA the choice of carrier is limited to either AT&T or T-Mobile because only they support the WCDMA (HSPA & EDGE) 850/1900 frequency bands.
Second, note that the tablet only supports the Edge (2G) 850/1900MHz frequency bands, but does not support the WCDMA (HSPA) 3G 850/1900 frequency bands. And, in the case of my PiPo M8pro 3G tablet, based on its IMEI number, the AT&T provisioning system identifies it as a 2G device of "Unknown Manufacturer" and "Unknown GSM".
For the most part, to be able to utilize other than the very slow EDGE (2G) networks, you will now need to have a tablet that supports the 4G T-Mobile 1700MHz band or AT&T 2100MHz band. It is my opinion, that at this time there is no 3G advertised Chinese tablets that will work satisfactorily in the USA.
I am a little confused about some information I found on Verizon's Note 3 Page. It says that the Note 3 will be a CDMA phone but then lists the following bands:
CDMA Data – 1x and EVDO Rev0/RevA
LTE: B13 (700MHz)
Global Ready (GSM/EDGE: 850/900/1800/1900; HSPA/UMTS: 850/900/1900/2100 MHz)
(original link: http://www.verizonwireless.com/b2c/...t&action=viewPhoneDetail&selectedPhoneId=7194)
Does it mean that if sim-unlocked, it can be used internationally, and how, if it doesn't take a sim card? If it can be used internationally, I would much rather buy a Verizon (for the US) instead of AT&T. I use AT&T only because it's a GSM carrier.
I don't have the answer but I can recommend you to contact Samsung wireless. They certainly have much more credibility.
Good luck

All Verizon 4G LTE devices take SIM cards. They have to, since LTE is based on GSM. Also, historically, Verizon doesn't carrier-lock the LTE/HSPA/GSM part of their 4G LTE phones, so SIM cards from other carriers will work in a Verizon LTE phone out of the box.

I found the answer here, by the Answerer #2. The 4G/Data part of a global ready phone is GSM compatible, and only that part can be locked for data internationally; the calling part will still depend on CDMA in other countries. If that information is accurate, I will stick to an AT&T Note 3.

Truth be told. LTE has more in command with CDMA in terms of radio/air interfaces. It covered within 3GPP standards (GSM then EDGE, the UMTS, HSDPA, etc). Rather than 3GPP2 for CDMA1x and EVDO. That's why Alcatel Lucent had a leg up on LTE since its deployment is more akin (specterally) to CDMA. But they dropped the ball, and except for the US and Some Asian markets, the rest of the world has 3GPP based networks deployed.
the Simple version, is LTE is not directly compatible with any 2G/3G technology, but since its covered in 3GPP, the standards evolved quicker to ensure GSM/EDGE/HSDPA interworking.
And beyond that.. what most people dont know, that interworking doesnt really work that widespread yet. In the US most mobile handsets operate on dual frequencies (especially all VzW models, ATT models are catching up) so they effectively talk CDMA1x and LTE at the same time. iPhones do not support that capability, but GSM has work arounds to allow talk+data.
i'll go back to me hole now
(btw.. anyone with iOS7 and ATT.. what out you've got problems you dont know about when going back forth from 3G to 4G.. I know since at work we talked about how to fix it..
I believe a rumor was that it has the same LTE baseband chip as the iphone 5s so that you could potentially use the Verizon version on AT&T and T-mobile...any truth to that?

Not true, I put a T-Mobile SIM in my Verizon Note 2 and made calls, sent texts, and used data on GPRS, EDGE, and HSPA+.

Nice! Was this native to the stock Rom or is a custom one needed that has this ability "unlocked"?

Global-ready is basically verizon's way of saying that it has a GSM 3G radio as well as a CDMA radio. That allows the phone to operate in Europe where there is no CDMA service. You can purchase international service from Verizon, or purchase a SIM from a European carrier while overseas. All verizon 4G phones have a GSM 4G radio anyway, because LTE is GSM.
(This means that with an LTE carrier in Europe, any 4G Verizon phone can get data in Europe even if they can't place voice calls (VoIP still possible)).
If I am not wrong with what I am saying, Verizon LTE phones only support LTE BAND: 13, which means that IF you are willing to use 4G with different carrier, they have to support LTE band 13. I have tried to use my Verizon Galaxy Note 2 in South Korea, I was only able to use 3G network via WCDMA, I wasn't able to get LTE service at all. Correct me if I am wrong.

the different N3 variants due in fact support different LTE bands, so you are correct. Minor point not worth nitpicking from earlier post, GSM is not LTE. they both evolved from the same 3GPP standards body, but portions spread spectrum nature of LTE is more similar to CDMA than GSM.
I went to Korea last October, and they wouldn't allow prepaid 4g LTE. They would only allow 3G for prepaid service.
I had a note 2 rooted and custom rom when I went. I'm a US citizen and you have to wait about 2-3 days before you are allowed to sign up for any plan on what they told me.
