If I had an unlocked Lumia 900, would I be able to activate that on Sprint?

I think its a GSM device and Sprint is CDMA.
So no.
This is correct. You'll need to wait for a CDMA-2000 version of the Lumia to be available in the US (I think they're doing one of the Lumia 800 in China?) or you'll need your carrier to use the predominant cellular technology used by most of the world...
Many Verizon customers are dreaming for the same thing. Look over at Verizon's web fourms...pages of people begging for it.
It's GSM based, It will only work on AT&T and MAYBE TMOUS (both GSM carriers) but, will not work, AT ALL on Sprint or Verizon.
Trust me, if I could activate it, I would of owned one already...
Do you ever see a day when VZW will ditch CDMA and start using GSM? I hate not being able to use my phone with another carrier. I also don't see any real advantages to CDMA. Any thoughts or opinions on if you see this happening?

Verizon will switch from CDMA to GSM, probably never. CDMA is very well suited for covering long distances with a minimal number of towers. Therefore, CDMA is the best platform for countries with large land masses. CDMA is more secure, and the phones are more energy efficient. Also, CDMA phones produce far less EMI.
If you really need the international roaming, there are Verizon phones with global capabilities. Or switch to T-Mobile or AT&T, and deal with that headache.

I would love to see verizon ditch CDMA for GSM! Its a pain to have accumulated phones that I will not be able to use once I switch to a GSM provider. The problem is that it doesn't seem like there is any incentive for Verizon to WANT to switch from CDMA
CDMA is better than gsm in some ways and gsm is better than CDMA in some ways I prefer cdma

Verizon already has been rolling out LTE, is it not just a matter of time before they start to put all services onto that? I would think that at some point Verizon just won't need CDMA anymore.
There lte is CDMA...

Nope its CDMA at a higher frequency to allow faster speeds. How do you think these little companies do it like cspire? They can do it for cheap on CDMA

wish they would just because i'm not stuck buying a new phone whenI leave them.
Trying to decipher the threard now on if I can make my Droid 3 use ATT in USA
LTE is based on GSM technology. On current Verizon LTE phones, CDMA is used for voice and texting (and data when there's no LTE), but data (when there is LTE) goes over LTE. That's why you guys have SIM cards in your CDMA devices.
What verizon is planning to do is abandon CDMA for completely LTE phones in the future. What this means is voice, texting, and data will go over LTE, similar to VoIP. It's called VoLTE, which means Voice over LTE.

It's actually at a lower frequency than their CDMA bands. 700mhz band. Lower frequency has better wall penetration. Frequency has nothing to do with bandwidth either.

I know for a fact that lte runs on CDMA at cspire it may be different but there isn't no sim on cspire phones and they couldn't afford to upgrade all there towers with gsm anyway so is there different kinds of lte?

GSM doesn't just mean SIM card. LTE uses GSM protocols. Sprint is the same as CSpire; no SIM card slot. However there's a chip that emulates a SIM card inside the phone. It's probably the same case for CSpire users. The HTC One on Sprint has a SIM card slot though. So does the iPhone 5.

Well, if a phone supports LTE, it doesn't necessarily mean it can do GSM. For example, the HTC Rezound and most newer phones on Verizon do GSM, but only because the phone happens to support it because the chipset is designed for global roaming. But the Galaxy Nexus on Verizon, for example, doesn't do GSM even though it can do LTE.
There was a guy who took the Photon Q on Sprint (the Motorola slider), unsoldered the chip that pretends to be a SIM card, and soldered on a SIM card reader. He was able to use normal SIM cards in his Photon Q afterwards.
don't some CMDA phones have sims though?

Those are phones that also had a separate GSM radio in them for traveling abroad (like the DROID 2 or even the Touch Pro 2, which were not LTE phones).

Ahh, ok. nice to know. Going to attempt to get my D3 on USA ATT this weekend. I hope it works as I really don't want to shell out money for a new phone. I like my D3
There going to leave CDMA eventually but not for GSM. There is a new form of LTE they will eventually adopt because its backwards compatable with the original LTE . Than they can pull all of there cdma and older lte equipment along with the 1x stuff that has been phased out and removed as it dies.
I dont see all of this happening for another 4-5years for the full switchover though and its posable they may leave cdma in some markets to help coverage as it seems some areas LTE just eats it.
Hi guys I have a question hopefully someone can help me with. I have the myTouch 4G Slide from T-Mobile but I want to use it on Verizons network. I know how to root and unlock the boot-loader but are there any other steps I need to take before this is functional? Any help would be greatly appreciated.
Version uses sim cards right? If so just search the threads here on how to sim unlock your phone, I believe I read one or two here before. You can also have it unlocked by tmo if your on contract with them or you can buy sim unlock codes

Verizon uses CDMA. The MT4GS is a GSM phone, so there is no way to use it on Verizon's service. It doesn't have a radio that is compatible with Verizon's towers.

Exactly! There is absolutely no way to get this phone, or any GSM phone that I know of, to work on Verizon's system. Even T-Mobile's new LTE service is different than the LTE from Verizon (not that this phone can work on either of those, either).
Haha, couldn't remember myself, hence the foggy reply! CDMA is such a pain, makes me wonder why anyone uses a carrier with it, I mean unless you never travel or want your phone to only ever work with one carrier....

There are a few Verizon and Sprint (both CDMA carriers) that have GSM backup. They market them as their "World Phones". The iPhone5 is one of them. If the phones have the GSM portion unlocked (Verizon automatically unlocks theirs, Sprint will unlock on request after a certain amount of time), you can use a foreign SIM and the GSM radio of those phones. But, you have to be careful, the phones default to the CDMA and if you have roaming turned on, in some countries that could be a VERY expensive oversight with roaming charges.
I was wondering if you guys could help me understand something as I don't know much about cellular carriers. I currently own a Lumia 920 on att and was looking to trade it for a galaxy s3. I found someone who will trade with me, but he is on Verizon and the phone is with Verizon. I applied on att for an unlock code so that he would be able to use it, but I'm not sure how the whole GSM vs cdma works. What would I have to do to make this swap work if that's even possible?
thanks in advance.
It is cdma vs gsm networks. The gs3 on Verizon can work on gsm networks but was not designed to be utilized solely on a gsm network. I would stick with s phone from your current provider

so im trying to find a non-smartphone that works on att. i was just going to stick with att phones but i see alot of verizon phones that i like. i understand that an at&t phone needs to be compatible with umts 850-1900 for 3g specifications since att shut down 2g but what about tmobile/verizon specs? i see alot of verizon phones with cdma 800/1900. would that mean it would work withh att after unlock?

I wouldn't bother with a 3G device, many networks are dropping or will be dropping 3G in the very near future, it would be a waste of time, money and headaches to go for a device that is quickly coming to the point of no longer being supported.
