Anybody know does the Motorola ELECTRIFY M XT901 (U.S. Cellular) have GSM module? It great phone, I'am realy love it, but I want to use it with GSM carrier. Maybe need some software or hardware modification?
Motorola Electrify M on GSM network
so I would like to know: will it work with this phone GSM network (no CDMA and LTE)?
Can anybody insert sim of GSM carrier??? What will hapends in this case?
The Electrify M XT901 uses a different baseband chip than its RAZR M cousin. It lacks GSM radios and 5GHz Wifi. The phone itself also lacks GSM antenna. There are no options in the stock ROM for Global or GSM modes, and even though 3rd party RAZR M ROMs can work in the Electrify M, those options won't work due to lack of GSM radio.
I don't make it a habit to necro-post, but just thought I would answer this question because it's one of the first Google hits when searching for this info.

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.

what i often wonder is if there is a 1700 (tmobile) radio buried somewhere deep in the RAZR.

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.

And yes at this time no carrier (that I know of) carries voice over LTE. It's still in the experimental stages.

Hi,
I live overseas and my network uses GSM 800/900/1900/2100 and UMTS 850/1900 (sams as AT&T)
All Verizon Razr come with SIM slot?
Are they UMTS 850/1900 compatible? Will I get 3G and H data?
What about Razr MAXX? Does it come with SIM slot?
I need to SIM unlock it or is it ready to put any micro SIM?
Hope you can enlighten me with this info.

the cdma and gsm razr both have the same razr, with the cdma razr on ics you can use non U.S. sims no problem. so if you are oversea from the us you could get the branded cdma razr cheap, put it on ICS and use your sim. it should get 3g/H as my razr (gsm did with an at&t sim) so in global mode the cdma should
(don't take me a100% on this, but i am sure from what i read, but i am in the us. so i can't test it myself. maybe wait till someone else chimes in)

Thanks for your reply.
I am asking this (and so is my friend on the post above this one) because Verizon CDMA phones are always cheaper than GSM.... even cheaper if the have BAD ESN...
So, every Motorola RAZR have micro SIM Slot? Are they unlocked or I need to buy the code? Do you remember the Droid 2 Global? Those had SIM slot's but some of them had they unlock code changed and were IMPOSSIBLE to unlock... hope this is not the case with the RAZR.

from what i've read on the forums you need to either put the verizon razr on ice cream sadwhich (4.0.4) or use the hack to enable global mode in gingerbread (2.3.x)
so no unlock code. and yes, the verizon razr uses the micro sim for 4g lte sim

i have the gsm version (xt910, sorry i wasn't as clear about that as i thought, i said gsm, should've put xt910)
the xt910 has the cdma disabled and the xt912 has american gsm blocked.
and I've seen a few people claiming they flashed an xt910 to a cdma network like metro (it does have the radio, and couldn't the flashing program give them the esn/ect?
but i use it on simple mobile (so only edge for me. i might go to t-mobiles $50 plan if the non throttled edge is faster)
Hi
just purchased a XT912
its on 2.3.6
want it to be used in India for gsm purpose
can anyone help me
what should i do to get gsm going in the phone on GB
or should i update it to ICS and simply insert the gsm sim and change network to gsm and start using ?
i havent used this phone ever before.
regards
I think that is impossible :S
The hardware in the CMDA version is diferent to the on in the GSM, so you would only be able to get CMDA signals and not GSM
You are wrong
The Verizon version has both GSM as well as CDMA radios
Just updated it to ICS and GSM is working fine.
Though all gsm operators outside us will be working

Hello Xda I have a really important question. Im thinking about buying a razr maxx for verizon. The model us different its a xt912m. But my question is, does this phone have any gsm support at all for out of the country (U.S)? Ive searched everywhere on the net for this information and cant seem to find it. Everyone either has another version of the maxx (xt910, xt912, or xt913) but very few with the "M" after the 912. and so I cant get the actual information. Its a 16gb phone with 1 gb of ram. I guess it was a limited edition. Can it be unlocked or support gsm cellular bands at all? Thanks!

If you want a gsm its the xt910, I believe. The xt912 and its variants are all CDMA.
Ok, so i'm starting a new thread regarding the MOTOROLA RAZR MAXX, not to be confused with the VERIZON Droid Razr Maxx. I have a Motorola razr maxx XT908, it is GSM and UMTS compatible and CDMA as well. I've spoken with Verizon, AT&T, Net10, Motorola and asurion and nobody can help me. However, the phone is capable of 3g GSM HSDPA , so I'll need to remove the Verizon XT912 software and find GSM HSDPA compatible software. This isn't a case of simply wanting to move to another network, it's driven by the lack of Verizon service at my home.
Basically its an XT908 that thinks it's an XT912. Since I won't be using the MEID number with CDMA it will work with a GSM 3g HSDPA sim card.
Does anyone know what software is available out there to make this happen? Thanks!
How can I convert razr xt912 to an xt910 GSM , it's an xt908
Can Someone tell me, step by step what I need to do to convert my Motorola razr maxx xt908 which is running Verizon xt912 to an xt910 for use on US GSM hsdpa networks? This phone is unrooted, bone stock and I need clear instructions on what I need to complete this. I'm completely lost in the wasteland of information on rooting, backing up and what I need to do this. I will glady donate to a reliable source for this operation.
Is there a way to wipe the traces of Verizon's system version, baseband version , etc and install a GSM based version?
There must be!!
I'm confused why you think you have the xt908 if it has the VZW xt912 software and it's never been modified. Just because the phones share most everything does not mean the software / firmware is compatible between the 2. For future reference, some of the Motos can be unlocked, and the xt912 is already unlocked for international use (after the ICS update and beyond) but will not work in the US for GSM. The xt907 and xt926 (some variants) can but the quest for unlocking the xt912 for domestic GSM use never went anywhere.

I've researched it, I spoke with asurion, they sent me this NIB Motorola razr maxx xt908 after they sent me a refurbed phone that still had problems. I spoke with tech support and asked them if they provide this phone to non Verizon customers and he said yes. The bottom line is, the phone has both cdma radio and GSM, but the Verizon model has the gsm usage blocked in the US, all I'm looking to do is convert this phone over to a GSM based software, similar to what Asurion does when they get an order to replace a phone. If you are Asurion, wouldn't you want one model phone that you can configure for use with any carrier? So they get the order to replace, load the Verizon firmware, pack it up and ship it out. I also spoke with Motorola about this, they didn't say it couldn't be done, all they said was I'll void the warranty. The phone was new, it says XT908 right on it, so obviously its able to run different versions of firmware, otherwise I would have an xt912. not an xt908 running Verizon firmware. There is no branding on this phone, it does not say Verizon on it.
This is what I want to do: back up the phone using android SDK, completely wipe the phone, not factory reset, no safestrap, then install xt910 firmware for use with gsm carriers. My only other options are to ebay it for 100 bux or give it to my kids to play on. The problem I'm having is finding accurate resources with links that work to complete it.

My understanding about the xt908 is that it is a different variant for smaller US CDMA carriers and isn't possible to unlock for GSM. Definitely wouldn't be able to put the xt910 firmware on there.

this is my phone, http://www.gsmarena.com/motorola_razr_maxx-4666.php
the specs are primarily hsdpa gsm, umts
This is what my phone thinks it is via software and imei
notice CDMA is listed as other not the primary radio feature
Unfortunately, that's actually not it. That variant doesn't have CDMA meaning VZW software wouldn't work at all. Moto decided to do their model naming while they were drunk. They also have 2 different versions of the xt912 and xt926 (the it's just that Maxx and non Maxx variants, but still...) But yours is a repurposed one from a small CDMA carrier like this: Motorola RAZR™ MAXX XT908 • Illinois Valley Cellular These are NOT the same, despite the model # because they do make a CDMA xt908 and GSM only. The software / firmware will not be compatible between.
