As I can understand the xt910 in Europe doesn't have 4g but is this just hardware that's not being used. And will it be active with a update
I ask because the us version has 4g lte is it a totally different phone.

Even if they activated the latent LTE chip, its supported frequency would be useless in Europe.

Most certainly not. LTE is far from having worldwide standard bands, and it currently looks like the closest to a standard will be 1800mhz rather than the 700mhz Verizon uses.
Have a look for the wonderful marketing blunder Apple made by selling the iPad as a 4G device in Australia where the only LTE network is Telstra's on 1800mhz.
There's also issues like TD-LTE vs. the other standard I forget the name of right now.

2,5Ghz LTE will be used in Brazil because 700Mhz frequency is dedicated for TV broadcasting. Experts says 700Mhz is better because uses less antennas and are more compatible with actual devices, like vrz ones. Hope they change their minds in time. :/

Hello
I have a question that has been bothering me and I cant figure out the answer. As I am a noob I have not yet gained the knowledge to understand where most of these tutorials that i have found online are starting at. My question is "How do I port a CDMA rom to GSM".
I am trying to get the Droid Razr Eclipse rom which is a CDMA rom, to work on my GSM phone. I also would like to be able to make some small adjustments to the rom as well. Like for example. On the stock rom for the droid razr I have the ability to control my music from the lock screen however on this rom, the eclipse rom, I cant do that I must unlock the phone, and then change the song, which is a hassle if i i am driving or playing video games. I also would like to be able to change the look of the calender app that comes with this rom. because I feel that is a bit too bulky for my taste. Other than those three problems the rom is great.
I hope I am not offending the creator of this rom by asking how i can change things in it please forgive me. However thats all I would like to change other than that the rom is great.
I would be greatly appreciated if I can receive an answer asap
Thank you,
The Noob ejay010

After CES, I'm beginning to put some serious thought into LTE and this phone. Dumping AT&T at this point is looking fairly good, as I've loathed their customer service for consistently soft-bricking my older phones due to their inability to properly unlock a phone.
How well does this phone handle roaming, especially in Japan, the UK and Australia? How compatible is the CDMA2000 EV-DO Rev. A. standard? I need to do a lot of travelling to these places and don't want to be short-changed. Does this support UMTS 2100 or international 4G? I plan to use the "buy a prepaid SIM" method.
Or should I be carrying around my unlocked Captivate for roaming?
If you want traveling to Western Europe (like in UK), forget it because GSM rules there. Just notice that the GSM represent 80% of mobile phone market but there is a website you can find the CDMA coverage in the world:
http://www.cdg.org/worldwide/
EDIT: About the 4G, a very very very few countries have it but it can be HSPA+ or WIMAX instead of LTE.
Another website for GSM coverage: http://www.worldtimezone.com/gsm.html
So, what you're saying is basically: Tote around the Captivate if I'm going to Europe, use the Thunderbolt for Japan?
In short answer, Yes
But you can't use the 4G Lte in Japon because it doesn't exist (yet).
Anyway, there is one carrier available which support the CDMA in Japan according to the website.

I do know that KDDI supports CDMA2000 and 1xEV-DO Rev. A on the right bands in Japan, so I'm hoping that it's enough. I don't need data roaming that badly, and if its service is comparable to Verizon's EV-DO service, it's good enough.
If youre gonna roam, bring along the captivate.

Sir,
I want to buy Galaxy SII duos. It works with CDMA2000. However, I used to go to Hong Kong. I want to use 3G (i.e. WCDMA). Can I root the ROM so that it can works with WCDMA?
I have an atrix that is unlocked and has a T-mobile sim card. But its stuck on Edge and never been on 4g let alone even 3g. Is there a custom rom and/or kernel that can fix this issue?
The atrix isn't 4G capable (lacks the hardware) and T-mobile uses a different frequency for their 3G networks that the Atrix doesn't support.
So yeah you're stuck on edge as long as you're using T-mobile on the atrix
Seriously?

I have been considering the Atrix 4G from AT&T. it is advertised as 4G by ATT. I ready a couple reviews that said it was slow, but I assumed that might be from all the bloatware. I guess I should be looking at a different phone, if the Atrix 4G is really not 4G.
First find the specs of the device. Only devices listed as LTE are real 4G. You can find it in radio frequencies. At&t only has a few but verizon has a plenty to choose, although according to user feedback 4g devices are battery hogs, while on 4g of course.

Well that sucks... I guess I'll be continuing my search. I'm new here but am loving the available information and the responsiveness of the members. Thanks again.
I know Verizon Wireless uses a CDMA network for their services. But LTE is GSM right? I remember the UMB standard which gives 4G on CDMA was abandoned in favor of LTE. So does that mean the Droid RAZR/MAXX have both GSM and CDMA radios? Also is it possible to have voice/video calling on 4G LTE?
Yes, the XT912, XT910, and Maxx phones use the same chipset and have GSM and CDMA radios. They have just been disabled for the different regions.
LTE is entirely separate and different then CDMA/GSM. LTE uses the 700Mhz spectrum, while GSM/CDMA uses 850Mhz to 2100Mhz. Eventually, once LTE becomes more mainstream will we see chipsets that support GSM/CDMA/LTE/HSPA+
The Razr has the capabilities to be used with GSM and CDMA, carrier depending. But not LTE. It simply doesnt have the chipset.
And 4G is a loose term. It is used in reference to LTE, and HSPA+. Since our phone only supports data speeds up to 14.4Mb down (HSPA), it is not a 4G device.

it often makes economic sense for a large scale electronics manufacturer to make only a single bit of hardware and then enable/disable various bits in software. Intel has been doing this for almost 30 years. I've seen several references to all RAZRs having identical hardware including one from a Verizon employee who claimed could flash a RAZR from gsm to cdma and then back again.

Nah, iFixit did a teardown and found a Qualcomm MDM6600 baseband. That doesn't have T-Mobile's frequencies. If it had the option for pentaband GSM, Motorola would definitely market the hell out of that - think about how many more customers they could get.

Your right. I had no idea that Verizon had a LTE version. I guess thats the difference between the XT910 and the XT912. Im curious to know if the XT912, unlocked, will work with other LTE carriers besides Verizon.
On top of that, I am unable to find any ifixit reviews of the XT912. Only the XT910. Is there actual hardware differences?
My question is since LTE is GSM and Verizon is NOT GSM, how do they manage to provide LTE service? Does the phone keep switching between CDMA and LTE or what?

When you're in an area that has LTE coverage, you'll get LTE. When you're in an area that does not have LTE coverage, the phone automatically switches to CDMA.
The Verizon RAZR does have a GSM radio. But as others have said, it's disabled. Verizon has said they're going to enable the GSM radio on the Droid 4 for international use in the future, and since the Droid 4 and the RAZR are pretty much identical internally, many people think that Verizon may eventually enable the GSM radio on the RAZR as well at some point (though there has not been any official or unofficial word from Verizon/Motorola on that).
To answer your questions:
1. They are using GSM. They partnered with Vodafone in 2007 and have been building their LTE network since then.
2. Yes. CDMA for 3G and LTE for 4G.

Riight! So the DROID RAZR keeps switching between LTE (which is GSM) and Verizon's CDMA network right? Which means that it HAS TO have a GSM radio in it for LTE to function? Also I heard voice is NOT possible over 4G, is this true?

Like myself and others have already said, there is a GSM radio in the Verizon RAZR. It is just not possible to use it. The Verizon RAZR will not work on a GSM network (at least not until the capability is enabled by Verizon or a developer).
VoLTE (voice over LTE) is possible, but no one is really doing that yet.
LTE is a form of GSM, but it's best to think about the two as completely different since in the real world their manner of operation is different. So don't think of LTE and GSM as the same type of technology that's interchangeable. Think of each as separate from the other.
Also, don't confuse what is often referred to as 4G on GSM networks (HSPA+) and LTE. They're also completely different. HSPA+ is often called 4G, but it's actually just an extension of existing 3G technology. LTE, for all intensive purposes, should be viewed as a completely different technology.

I agree with you 100 percent. Except the fact that LTE is not a form of GSM nor CDMA. Its completely different.
The funny part about HSPA + is that its HSPA with mimo technology. Theoretically making it 3g on steroids.
razr maxx
There are two separate models of the Razr Maxx.
the first one, the xt912 released months ago is for the US market and is a CDMA phone
here s the link with all the specs:
developer . motorola . com / products / droid-razr-maxx-xt912
the second one, the xt910, is a gsm phone. and works on 2g and 3g networks around the world.
Connectivity
GSM 850/900/1800/1900,
W-CDMA 850/900/1900/2100
as u can read as well on Motorola website.
i cant post entire links due to restrictions to my new account but if u go on typing the url without spaces u will see all the specs
developer. motorola . com / products / razr_maxx_xt910
I have already bought the xt910 and i use it in Australia on normal 2g, 3g and 3.5g capable networks. It works on Telstra Next G network as well. The battery is amazing. 2 days of intense use in 3.5g without recharging it. 5 days of moderate use (gps - bluetooth - sync off) without a charge.
If you head over to the bionic forum a developer has been able to unlock the GSM radio for the RAZR/Droid 4/Bionic. It's compatible with ATT HSPA and T-Mobile edge. As far as I know it's still a work in progress.

Excuse the noobish question, but to make sure I have this right - You need both 1700 and 2100 bands for the 3g or 4g to work at all, correct? Was looking into buying it once its released but that may be a deal breaker if no speedy internet.

I'd like to know about that as well
I think everyone here just wants to know when the hell it'll be coming out to our own carriers. I need a new phone but I'm not waiting until Fall for one.
Doesn't t-mobile uses the 1700/2100 for 3G and 2100 for 4G? so it would be EDGE and 4G.
So your implying that 4g will in fact work? I thought you needed both bands for 4g to work.
I'm in the Philadelphia area and really need to know if this will work or not.
If I can get 4g, ill be preordering the phone asap. If not.... I'm still undecided.
nope, im asking if thats the case. i need to ask the dude that know, since he is the manager at the t-mo store if thats rite. but t-mo one should be coming out in month or two.
What T-Mobile calls 4G is really their 3G HPSA network. They have not yet rolled out LTE. So for you to get the T-Mo 3G, you need the phone to support 1700/2100 band, which I am not sure the international SIII model does, but I'm almost certain it does not. Therefore, you will only get 2G (EDGE) speed, which is around 10-15kilobytes per second download, good enough for web browsing and loading Google Maps, it's about 3 times faster than 56k modem.
The T-Mobile-locked model will support the HPSA+ 42Mbps speed and AT&T version will have LTE of course. Now whether if when this phone get released for T-Mobile and somehow it will preemptively support their future LTE service (launch in 2013), then that would be interesting (which inherently the hardware does support LTE due to the Qualcomm S4 chip to be used in American models). What I predict they will do is like with the Galaxy Vibrant -> Galaxy S 4G, so first release the HSPA+ only version, then release a slightly modified version that support LTE.
http://www.samsungmobilepress.com/2012/05/04/GALAXY-S-III
If this doesn't confirm lack of 1700, nothing does.
So basically, count on the international version not being usable (besides EDGE) on T-mobile. You'll have to wait for them to up with their own version.

Dammit why does T-mobile use such obscure frequencies!
Hey all...
A friend of mine would be visiting the US next month. I was thinking of ordering the DNA at a full retail price (obviously). But this term of 'unlocking' confuses the hell out of me.
What does it actually unlock? From what I read, it is already unlocked and can be used with ANY SIM around the world. So, my friend just walks in to a store, buys the phone and gets it here in Delhi, India for me, I pop in my SIM card and everything just works fine.
Is that right?
Do I need to be aware of something that might not work. There is no 4G here yet, but I use 3G. Will that work?
Everything from 3/2G, MMS, calls, Msgs...everything will work just fine right?
THANKS!
Most of the unlocking in the DNA forum is referring to the bootloader. Since Verizon is the Anti-Christ of cell phone carriers, they don't allow phones to be sold with an unlockable bootloader. However an exploit was discovered that allowed HTCdev (website to that is used to unlock non-Verizon/AT&T HTC phones) to see the Droid NDA as a different phone and then unlock it.
The phone is GSM unlocked out of the box. Meaning you should be able to put your SIM in, plug in your carrier's APN settings, and theoretically be able to use 2G/3G/MMS/SMS/Calls. However, I'm not sure what frequencies carriers in India use for GSM and if the Droid DNA supports those frequencies.
There are some CDMA carriers in India I believe. I don't know what steps need to be taken to use the Droid DNA on them or if that is even possible. (I don't think it is)
(if I did a bad job of explaining it, or got some details wrong, someone please correct me)
