So I know it obviously works on AT&T network but will it work on Verizon, T-Mobile or sprint?
Tmo only gets edge for me. Wondering if its compatible on other networks. Any workarounds I'm missing?
Have a feeling I'm stuck to att if I want 3g 4g... =[
That's correct. Only T-Mobile uses the GSM network that AT&T uses, but they use them on different bands so the high-speed data is typically only going to work on one network or the other. Sprint uses EVDO and Verizon uses CDMA (if I remember correctly), so phones for each of those networks will ONLY work on that network.
I tested my unlocked Nitro on an H20 wireless sim (which just piggybacks ATT) and it worked fine. The icon was even SAYING. I had 4G. A lot of 3rd party wireless companies are still using att technically, but great as a cheaper data alternative that avoid contracts.
I plan on using this phone off contract with a carrier like that once my Verizon deal expires in February.
Hope that helps.

Does anybody notice that Verizon is now using a Sim card, just like AT&T and T-Mobile? That's because their LTE network runs on the Sim Card and not built into the phone, like CDMA...
So technically, yes, you may be able to insert a verizon LTE card into your phone, and it might work, but you most definitely won't get their LTE connection.
You know what, I should try this at work tomorrow. My coworker has a Rezound. we can switch Sims and see if it works on both phones.
Make sure you have the proper LTE APN settings for each carrier or you won't see LTE or squat!
LOL!! I forgot about that. thx Repherb.
I have a Verizon CDMA version of the GNexus. Now from what I've read elsewhere and through searches, the SIM card is really only for data. Is it still possible for me to switch a carrier when I go out of the country? I had a Nexus One and all I had to do was swap out the SIM. I assume it would be a lot more difficult on a CDMA phone.
The country I am visiting has a similar CDMA network that I could hop on.
No. Its hardware locked to Verizon. Your only chance is the other carrier having a roaming agreement with VZW. At that point you could pay for an overseas plan. But even then it may cause issues because its an LTE device that still relies on the SIM for activation.
Your Nexus One worked this way because its GSM and relies only on the SIM card to change carriers. CDMA (Verizon) is different.

Hi,
Quick question, I know all about carrier locks on devices as such. Does anyone know if the Note 2 sprint has the capability to run on GSM only rather CDMA. I know sprint has it locked to there network. But interested if i get it unlcoked one day and want to put a sim into it if its possible.
thanks
Sim is embedded in the phone and is not replaceable, at least not without some serious hardware modifications. It also has no sim slot... So for GSM you're stuck with Sprints providers

Yea, sim cards, frequencies, etc...
There is a lot more involved in the two different technologies than just "cooking" up a ROM.
I don't believe it possible to change a phone from gsm to CDMA and vice versa. Nor can it be tdma, or any other wireless technology. They operate on different bandwidths.
Think of it as attempting to transmit FM radio on a AM station.

Two basic technologies in mobile phones, CDMA and GSM represent a gap you can't cross. They're the reason you can't use AT&T phones on Verizon's network and vice versa.CDMA (Code Division Multiple Access) and GSM (Global System for Mobiles) are shorthand for the two major radio systems used in cell phones. Both acronyms tend to group together a bunch of technologies run by the same entities. In this story, I'll try to explain who uses which technology and what the real differences are.
Which Carries are CDMA? Which are GSM?
Five of the top seven carriers in the U.S. use CDMA: Verizon Wireless, Sprint, MetroPCS, Cricket, and U.S. Cellular. AT&T and T-Mobile use GSM.
That means we're mostly a CDMA country. It also means we're not part of the norm, because most of the world is GSM. The global spread of GSM came about because in 1987, Europe mandated the technology by law, and because GSM comes from an industry consortium. What we call CDMA, by and large, is owned by chipmaker Qualcomm. This made it less expensive for third parties to build GSM equipment.
There are several variants and options carriers can choose, like toppings on their technological ice cream. In this story we'll be talking about U.S. networks.
For call quality, the technology you use is much less important than the way your carrier has built its network. There are good and bad CDMA and GSM networks, but there are key differences between the technologies. Here's what you, as a consumer, need to know.
It's much easier to swap phones on GSM networks, because GSM carriers put customer information on a removable SIM card. Take the card out, put it in a different phone, and the new phone now has your number. What's more, to be considered GSM, a carrier must accept any GSM-compliant phone. So the GSM carriers don't have total control of the phone you're using.
That's not the case with CDMA. In the U.S., CDMA carriers use network-based white lists to verify their subscribers. That means you can only switch phones with your carrier's permission, and a carrier doesn't have to accept any particular phone onto its network. It could, but typically, U.S. carriers choose not to.
In other words, you can take an unlocked AT&T phone over to T-Mobile (although its 3G may not work well because the frequency bands are different). You can't take a Verizon phone over to Sprint, because Sprint's network rejects non-Sprint phones.
3G CDMA networks (known as "EV-DO" or "Evolution Data Optimized") also, generally, can't make voice calls and transmit data at the same time. Once more, that's an available option (known as "SV-DO" for "Simultaneous Voice and Data Optimization"), but one that U.S. carriers haven't adopted for their networks and phones.
On the other hand, all 3G GSM networks have simultaneous voice and data, because it's a required part of the spec. (3G GSM is also actually a type of CDMA. I'll explain that later.)
So why did so many U.S. carriers go with CDMA? Timing. When Verizon's predecessors and Sprint switched from analog to digital in 1995 and 1996, CDMA was the newest, hottest, fastest technology. It offered more capacity, better call quality and more potential than the GSM of the day. GSM caught up, but by then those carriers' paths were set.
It's possible to switch from CDMA to GSM. Two carriers in Canada have done it, to get access to the wider variety of off-the-shelf GSM phones. But Verizon and Sprint are big enough that they can get custom phones built for them, so they don't see the need to waste money switching 3G technologies when they could be building out their 4G networks.

Porting a GSM rom to CDMA is not the same thing as using a CDMA phone on a GSM network.

I'm pretty sure all new Verizon LTE phones are unlocked because that was an agreement made with the FCC during the 700MHz spectrum auction. Someone correct me if I'm wrong.

I don't think the Sim card is unlocked... Its the phone itself. You'd need to get a Sim over where you are going.

Apologies. I meant that the SIM card slot was carrier unlocked, not the SIM card itself. Naturally you would have to purchase a SIM at the destination.
So does anyone know fir certain if it is GSM unlocked?

Verizon 4G LTE devices are unlocked out of the box
One thing to note here in terms of software phone locks is that all Verizon 4G LTE smartphones come unlocked out of the box. The reason why is that the spectrum Verizon is using to build its 4G LTE network had restrictions put on it by the Federal Communications Commission, which required the company to allow "open access" to the network. So as part of this provision, Verizon has decided not to lock those devices. That said, its 3G devices are locked.
So what does this mean for the average consumer? Let's take the iPhone 5 as an example. It's a 4G LTE device. A Verizon version of this phone comes unlocked out of the box. There aren't special codes that need to be entered in order to use it on another carrier's network. But because of the spectrum differences I mentioned above, a Verizon iPhone 5 won't operate on AT&T's LTE network. It will operate on AT&T's 3G network, which is based on GSM. So this means you can use the Verizon iPhone on AT&T, but you won't get the fastest Internet speeds on it.
The same is true if you take the Verizon iPhone 5 to Europe. You can swap out the SIM card and put in another carrier's SIM card, but the device will operate only on a GSM-based 3G network. And it won't operate on a faster LTE network.
And even though the phone is unlocked and uses the same CDMA technology and some of the same radio frequency channels as Sprint, an unlocked iPhone 5 won't operate on Sprint.
