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...

Hello gents, I'll start with a short story to get you into the thread:
Me and my girlfriend live in Venezuela, our service providers are not up to par with american or european carriers in terms of available devices, so we bought an HTC Magic for each of us last year to try out Android, everything was fine, I learned how to root it, install roms and such, and we had a pretty good run with the phone and the OS.
Last week we got robbed and they took away our phones, I decided to get a Nexus S for her and I found one at a good price on eBay(270$+shipping) however this one is branded for Sprint, will I be able to go to my service provider and just tell them to attach my account to the phone I bought on ebay? or are the Sprint and Verizon Nexus S locked to those carriers exclusively?
If the answer to the second question is yes, then a third question is raised, can I in any way unlock this phone to use it on my non-american service provider?
I have seen other threads and the replies are always "the Nexus S is factory unlocked." but I dont know if this refers exclusively to the ones sold in the UK or retail stores in the US.
I apologize for any noobish behaviour, I'm a big fan of devices and gadgets yet I lack a lot of the technical skills you all seem to demonstrate.
Thanks in advance.

There is no such thing as a Verizon Nexus S. Sprint Nexus S have different radio bands than the regular Nexus S (I9020T/I9020A/I9023) and features a 4G radio with it. You have to make sure that the phone is compatible with your carrier's bands. Another thing to note is that the Sprint Nexus S is CDMA (No SIM card) as well.
All Nexus S models come unlocked regardless if you're on the contract or not. Sorry to hear about your incident
The model I bought is GT-I9020T, according to people on the internet(random links on google) this model works on GSM frequencies of 850, 900, 1800, & 1900. It supports UMTS 900, 1700, and 2100 frequencies.
My current provider works on 850 and 1900 for GSM and 850 for CDMA.
Do you think I will have trouble using the phone I bought for my girl?
I feel terribly dumb when I ask this, I cant explain why, hehe.
Oh, I think I figured it out, I bought for her the non branded GSM version, so yes, it will probably work on my provider.
But what happens if I buy a Sprint CDMA one for myself? Those are definitely cheaper, and CDMA seems to be better down here, at least more stable.
Thanks for your replies, and simpathy, it's been a rough week without a smartphone for both of us.

I'm not sure and I wouldn't say the CDMA version is more stable. I personally never used the Nexus S 4G but from what I can tell from threads is that there are problems with WiFi or something of that sort.
You might want to ask the carrier yourself via phone to see if it would be compatible or so. Just let them know about the bands the phone supports.
And that's interesting if your carrier supports CDMA and GSM.
CDMA = No SIM card
GSM = SIM card
GSM is more popular around the world. Just including that just incase!
Alright, so I talked to my carrier they said the following:
-If I buy a CDMA phone with no contract on the US I will be able to register it on their network.
-If I buy an unlocked GSM phone I can register it on their network.
I guess I'll have to buy a couple of GSMs just to be sure... even tho they are about 100$ more expensive.
Thanks for all the replies, catch you later!
This question is from ppl where they have no carrier boundation but all ppl can give their opinion Can i buy a android smartphone from a carrier based company like at&t or t-mobile and bring it to my own country where is no carrier boundation and get the phone rooted/unlocked will it be able to run normally like other phones/unlocked phones? I'm asking this coz i live in a non-carrier bound country,cost of unlocked/sim free phone is 550$ and carrier bound is 150$. Now even the dumbest would had understanded why im asking it Plz answer this coz i dont know it. Thanx in adv.
Yes if you can get it unlocked it will work just like an unbranded phone. You have to be careful with the frequency bands though. T-mobile uses the 1700 band which isn't prevelant overseas. AT&T phones work well all over the world, as they use the same bands as most other GSM networks. Verizon and Sprint use CDMA instead of GSM, so they would be useless for you.

Thanks for ur response btw in my country 900/1800 band is used. Can u tell me specifically other than cdma network which carrier uses this type of bandwidth?
I'm sure you guys have heard that T-Mobile will have a joint venture with Verizon (LTE deal next year).
So the question is, do you guys think the Lumia 900 will work with T-Mobile's future LTE?
Tmo will use some of AT&T's and Verizon's spectrum, so there's a slight chance that it will work. What do you guys think?
It will probably work, yes. T-Mobile is also apparently moving some of their current 2G capacity (which uses the same bands as AT&T, hence why you can get 2G on T-Mobile with an AT&T phone) to 3G, bringing essentially full compatibility between the two networks. I don't know any details as to when, though.
Of course, your Lumia would need to be SIM-unlocked.
Hey guys, i would like to buy an one s the next days but i have an important question, since the c2 [s3 processor] will be the only one sold in the future in some european/asian countries (not in mine, just s4 here):
whats with CDMA / GSM? i read that t-mobile us has gsm phones but does that mean that the one s is only sold in the gsm version?
i am just asking because i don't want a phone without "enough" custom roms in the future, because there will be some for the c2 version only and if there are a lot for cdma only it won't be much for a european s4 gsm version.
thanks!

CDMA and GSM are different ways of transmitting radio (cell phone) waves.
In the U.S., to my knowledge, only Verizon uses CDMA. All other carries use GSM and most international carriers also use GSM. If you buy the phone from T-Mobile US, you can only buy the GSM version. If you buy it from Verizon, you can only get the CDMA version (this assumes Verizon actually sold the One S). I'm not sure about international carriers, but I would expect that most operate the same way. It would not be smart for a carrier to build out both CDMA and GSM networks due to the expense involved.
No matter where you get it or which SoC it has, S3 or S4, it will be GSM.
Thanks for your answers but it is too late, no one s from tmobile left in Vienna, they say one month... but I'm sure then they will get only c2...

Verizon and Sprint are CDMA. T-Mobile and AT&T are GSM. By extension, Virgin and Boost are CDMA since they piggy back of off Sprint here. We also have regional carriers like MetroPCS and Cricket kthat are CDMA. IIRC, T-Mobile US phones are better than AT&T phones with international compatibility.

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
