Can I unlocked a thunderbolt and put my tmobile g2 sim and used it?
No. The TB doesn't use GSM as a radio and is strictly CDMA for the phone side of things. Also, the LTE radio is different than T-Mobile's 4G radio. I'm sure somebody with a more technical side of why will come in, but that's the basic reason it won't work.
the only carriers verizon phones can switch to is cricket and and sprint (if either carrier is even willing to activate the phone on the network).
T-mobile can only take unlocked GSM phones (which would mean att phones)
I don't know enough about the thunderbolt being used on different carriers cause I don't fully understand exactly what data is being stored on the sim card. If it is only 4g data than theoretically It should be able to work only on sprint/cricket (without 4g, if they are willing to activate it).

As above, no, you can't use it on T-Mobile, you could take it over to Cricket/MetroPCS. Metro I know uses 4G LTE, so you'd be able to get everything out of the phone. However, I know roaming with that provider sucks unless you don't travel anywhere.

MetroPCS uses a different frequency band for their 4G LTE (I think they're on 1700, and Verizon is on 700), so the LTE won't work.

No you cannot take it over to Cricket/MetroPCS. The phone does not have a traditional MEID to allow it to work on a traditional CDMA network, and the LTE radio is not compatible with the "LTE" system that MetroPCS runs.
GSM
If you don't know what you're talking about then don't post it. Obviously you don't have a Thunderbolt to say if it can be unlocked or not. HTC Thunderbolt uses GSM network on 4G LTE. It can be unlocked, but haven't figured it out yet.
NO CRICKET OR METROPCS can be run on it.
I took out my sim to see if the phone will work on 3G. And the result is no. No way of putting it on cricket.

LTE is not GSM. The Thunderbolt runs on 700 MHz LTE and 850/1900 CDMA. It does NOT support ANY GSM/UMTS/HSPA bands. You CANNOT take it to ANY GSM provider. If you were able to unlock it, you MIGHT be able to take it to another LTE carrier, but ONLY if that carrier also uses 700 MHz for LTE (for example, possibly AT&T once they launch LTE), but even then you'd be able to use it for data ONLY. It is unlikely that you'll be able to use it on another CDMA carrier either (such as Cricket or MetroPCS) because it isn't provisioned in the way all other CDMA phones are.
Jumping on the bandwagon, no.

The TB will NEVER work on any other carriers GSM network. Period. End Of Line. It is not a matter of "unlocking" the phones. The LTE standard does not define interoperability with existing the existing GSM standard. The TB cannot operate on a traditional CDMA network (think Cricket/MetroPCS) because it is missing fundamental components required in every CDMA handset (there is no hardware MEID on the TB). Without an MEID the device will not work on a CDMA network, no matter how much unlocking you try. It will not work because the network cannot talk to the phone and there is nothing you or anyone else can do to change that fact.
What VZW has done is create a hybrid system linking their LTE network with their CDMA network. There is a reason dialing *228 does nothing on the TB. There is nothing for the system to update. All of the settings are created on the LTE network and are pushed to the VZW CDMA network on their back end. Your phone number is tied to your SIM card on their network, not your MEID. Want to prove it to yourself, take the sim card out of your TB and put it in another TB. Care to guess what happens? I'll help. The new TB you just put your SIM card into will now have your cell phone number. Now if you have been with VZW for more then 5 seconds you would know that with every phone prior to change your number you had to call customer service and they had to update your MEID and in turn you had to update your phone (*228) so the CDMA system knew what phone belonged to what number.
Tl; dr...: LTE and GSM are not interchangeable terms and technologies. LTE radios cannot function on existing GSM networks. TB is not a true CDMA device and will not work on a traditional CDMA network.
Ok I'm not a total Noob but if anyone can answer this question for me I'd be grateful.
Can I use a phone on at&t that is not offered by at&t, such as an eve from Sprint or a Droid x from version or a thunderbolt or the new Motorola razor!
At&t uses GSM which uses sim cards. Verizon and Sprint use CDMA which is a different technology. Sometimes phones will be global and have both CDMA and a GSM sim slot. My Droid 3 is global but Verizon locks US GSM carriers.
So basic if it has a sin slot and I can root it then yes, otherwise no
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.

All HTC Droid DNAs purchased through Verizon are factory locked. You can find ones online that may be unlocked but most are locked.
But, fortunately, it's extremely trivial to unlock an HTC Droid DNA and, from what I've heard, they work just find on GSM networks like T-Mobile, etc.
Good luck!
The dna is factory unlocked if your going to run on a gsm carrier just grab that sim pop it in and switch the network mode on your phone to gsm through settings.

You also need to change the APN settings to get Internet and mms to work. I just switched to Net10 AT&T version. You can also use T-Mobile just takes a different sim. You won't get 4g lte since our phone only has that band for Verizon but your 3g will be faster.

They are bootloader locked, not carrier locked, which is what he was asking. There's more then one type of lock on these devices.
So, all DNAs are carrier unlocked for GSM use, in case it comes up again and you answer :thumbup:
Tapatalked from my HTC DNA - Carbon
People out there still give misinformation about the DNA not being unlocked. The term doesn't really apply since its a Global phone. Both GSM or LTE Sim cards work so any GSM carrier and Verizon on the CDMA side will work.
thx guys for your prompt replies! The only other time ive used a verizon phone on gsm network was the droid 2 global. Which was "unlocked" well atleast sim unlocked but had a band lock and needed the TBH band unlock ( great group btw) to unlock the bands to use american gsm networks. I just wanted to confirm that the DNA didn't have a band lock like the droid 2 global.

nopes, no band locks..i have used the DNA on AT&T and T-Mobile in USA. Airtel & Idea in India with no issues. 3g worked on all 4 carriers.
what about cdma
would the phone work if i put in a cdma ruim from anothe operator (want to use this on reliance cdma in India)?
or does the bootloader need some fixing before it can recognize the reliance ruim?

My sister just moved back to the states, and has a Moto G8 Power that's unlocked, but only allows international GSMs. If I root it and install a custom ROM, can she use a USA SIM card?
Thanks!
You can use T-mobile and AT&T with a international gsm phone but not cdma networks like verizon, boost, US Celluar. i am not sure if you can use cdma networks on a international gsm phone but like i said you can use gsm carriers without rooting/flashing.
