Would I be able to use it on Verizon's CDMA network? I know that the Verizon Trophy has dual GSM/CDMA capabilities, but is every Trophy like this?
Thanks
Standard trophy is GSM only.
Yes, standard Trophy (codename Spark) does not have CDMA capabilities.
The Verizon Trophy (codename Spark_W) has completely different hardware. You'll want to buy a Verizon Trophy (just make sure it has a clean ESN.
Unlocking is only important if you want to use another carriers simcard in the phone on a GSM network!)
In short: Buy the Verizon branded Trophy to run it on Verizon Wireless, then look in the dev sections for guides on installing HSPL and flashing custom roms.

I have a hd2 tmobile usa version, i need a At&t friendly Nand rom. Whats the best rom out there for At&t????
Sent from my Desire HD using XDA App
as far as I know any NAND Android ROM should work on AT&T as it is not the ROM that controls this but a combination of you sim card, APN settings, and you having your HD2 sim unlocked. Wait for more replies though as I do not use AT&T and it might actually be a ROM out there that has certain things adjusted for AT&T, but what that might be I do not know.
This is true, the ROM does not control the radio. There are methods of flashing the radio to a different version, one that may work for the AT&T 3G bands. I am looking them up, but that is how you would flash the device to change the radio.
Hardware wise, the GSM module does support all world wide bands but what makes then different from one HD2 from one carrier ot another is the firmware version that is used in the phones that make them work on the network's bands. Correct me if i am wrong though.

Untrue my friend, the T-Mobile HD2 only supports the bands used by T-Mobile for 3G. If you sim unlock the T-Mobile HD2 you can use the device with other carriers but you will only get Edge for a data signal as the hardware only supports the T-Mobile 3G bands. There is a model of the HD2 that supports a different 3G band the same ones AT&T uses in the US, it is the Australian model that Telstra a Australian cell carrier released as they use the same bands as AT&T. go to "Official HD2 T9193 (Telstra 850Mhz) Discussion Thread" and you can learn more about it. I also saw your other post in another thread about trying to help your friend out getting 3G on his HD2 using AT&T. Unless he is willing to buy a Telstra HTC HD2 T9193 or have his T-Mobile HTC HD2 T8585 worked on to switch out the hardware for the hardware in the T9193 then he will never getb 3G with AT&T.
Just to answer your question, every rom is an AT&T friendly ROM, meaning, they'll allow you to talk, text and surf the internet.
What you DONT have is AT&T 3G on your tmous HD2. You'll be stuck with EDGE speed.
Thank you all 4 your help,greatly apreciated!! I'm in puerto rico where tmobile is still on Edge. But for some reason tmobile is still alot faster when it comes to receiving & sending MMS than At&t on this phone. Currently using Coredroid 1.5

its interesting they would use different hardware GSM modules for the slightly different models. I would think the radio firmware version woudl take care of that. Thanks for clarification. I assumed that all GSM modules would be built the same way.
Sadly they are not, this in my opinion is just cellular carriers trying to keep you locked to their networks cause the know most people don"t want to have to buy another device when changing carriers if they already have a good device. So they make it were branded devices can only utilize high speed data with it's intended carriers network. I think this is unfair to consumers, but again just my opinion.

I think there is technical reason. The various carriers have very different technologies. Even AT&T uses a different 3G network than T-Mobile, despite the fact that both are GSM. Sprint and Verizon use non GSM technologies that are even more different. When a device manufacturer makes a certain model, there is only so much room inside, and unless one wants a really thick and heavy device, a choice has to be made as to which hardware goes into the phone.
I'm not saying that they don't want you to stay on their network - they do, which is why they have those 2 year contracts in exchange for buying a discounted phone. But I don't think that is why the hardware is different.

I would go further with the discussion but I do not want to hijack this thread.
Hi,
I plan to buy the below mentioned phone from geb.ebay.in,
New HTC Trophy – 16GB – Black (Verizon) PagePlus 3G Windows Smartphone
my doubt is, whether i’ll be able to use it in India using any SIM. Can anybody explain me what this (Verizon) PagePlus exactly is, the listing says No Contract required, does it mean that any sim can be used in it?..,if not, is there any unlock procedure for it.
Thank you.

Usually US prepaid phones will be SIM locked to the carrier it was shipped with. You will have to call pageplus about unlocking the SIM.
Hello All,
I am thinking of buying a bad ESN Galaxy Sprint S5 from US. So, my question is will I be able to use it here in India after unlocking region lock? And secondly will I be able to unlock it using 3rd party website for unlocking cell phone for international use? And if I buy factory unlocked bad ESN Galaxy Sprint S5 will I be able to use it here in India with any GSM networks or not? Because S5 is supported both CDMA and GSM bands so sprint is a CDMA company thus if CDMA is locked through bad ESN if I unlock the GSM for international use I can as far as I read upon different forums. But want expert advice who have tried this
Regards
I was curious if anyone had tried dual CDMA carriers on their dual sim G4s. My understanding is that for 3G cdma voice the device itself is registered as opposed to a 3G GSM which registers the sim, so only one CDMA service could be active at a time. Changing to another CDMA carrier would mean going through Verizon's or Sprints's activation process each time you wanted to change to a different sim (this was my experience with a 3 sim adapter). I'd love to hear someone more knowledgeable chime in on this subject and provide some feedback on whether or not this is how it would work with a dual sim moto G4.
I'd love to have dual CDMA sims because I have free service with ringplus (Sprint MVNO) but it's spotty in rural areas, whereas Verizon has the most solid signal in the remotest regions.....however I think it's a pipedream. I am aware that you can do a CDMA LTE sim switch and get data without a problem (I'v done this with a triple sim adapter), it's voice and text that I'm interested in being able to switch to, without having to go through the activation process. And because I need this voice and data in remote areas without LTE, VOLTE isn't an option.
I hope that isn't too convoluted or arcane a question, I realize it's not a common scenario. But with the Moto 4G being carrier friendly to all the north american providers (GSM and CDMA) and having a dual sim slot, it's the first plausible solution to what I'd like to achieve.
Unfortunately, the only G4 models that have CDMA are the US models (XT1644 G4+, XT1625 G4, XT1607 G4 Play, XT1609 G4 Play for Verizon Prepaid), and the US models are only available in single-SIM format.
From what I've been gathering, there are no dual-SIM CDMA phones that fully work with US carriers available yet. The OnePlus 3 comes sorta close, it's dual-SIM and has CDMA Band 0, which Verizon uses in most markets, but at the moment it either works in 1x/EVDO mode for calls/text, or LTE mode for data. However, it's lacking CDMA Band 1 (Verizon & Sprint) and CDMA Band 10 (Sprint), so it's not ideal. It's also lacking Verizon's main LTE Band 13, and all of Sprint's LTE bands.
Slightly good news, though. The upcoming ZTE Axon 7 is dual-SIM and FCC testing indicates that it fully supports all US carriers, including all Verizon and Sprint CDMA bands.

I'll keep an eye on it.
Would the concept work the way I described in the first post though? I'm really curious if the phone would require sprint or verizon activation when switching cdma sims. I don't have a great deal of experience, simply my results with a multisim adapter. I was unable to test the adapter with a verizon and sprint capable phone (like a nexus 6) but tested it with an Verizon samsung s5 using gsm sims and a verizon LTE sim. The gsm sims (various at&t and t-mobile MVNO) were of course no problem, but switching to (or back to) a verizon LTE sim required teh verizon activation process (but not for data, as the LTE was active without activation).
Is it possible to have a dual sim (or even single sim) phone that supports both carriers (Verizon and Sprint) that could switch back and forth, or is the activation process simply inherreient with the way the devices imei's are registered on CDMA networks, and will always be required. For me going through the activation process for Verizon or Sprint when switching sims would simply preclude any practical usefulness with a dual sim cdma capable phone (although it would still have value as a dual sim with a cdma and a gsm sim).
Sorry for the late reply xtermmin and thanks for the info.

I can't speak for Sprint, as I have Verizon, but I do know that they're more restrictive than Verizon.
On Verizon, the only current restriction is a whitelist when you try to activate a SIM for the first time. You have to use a device that's in Verizon's "activation database", typically Verizon-branded devices, iPhones 6 and up, the Moto X Pure, and (at some point, if not now) the Moto G4 lineup. Once you have an activated SIM, you can stick it into any compatible device (be it from Verizon, another provider's phone, or even an unlocked phone that doesn't officially work on Verizon) and you should be good to go.
For example, I've been using my same Verizon SIM that I got with the HTC Thunderbolt (when it launched in March 2011) in numerous other phones (Verizon phones, US Cellular phones, unlocked phones, even some GSM/LTE-only phones) with no need to contact Verizon or use the website or anything. I've been able to just pop in the SIM, adjust the connection method on the phone if needed, and go.
As for your experience with using a dual-SIM adapter on the Verizon GS5, it might be due to the phone going into "GSM/LTE" mode when you insert a ATT/TMO SIM, but not switching to "CDMA/LTE" mode when you switch to your Verizon SIM (thereby only connecting in LTE mode). Might want to try setting it to Global mode (GSM/CDMA/LTE). The Verizon version probably wasn't tested for dual-SIM use, so it might just be the OS not knowing to switch to the other mode, or it might be an issue with the adapter itself.
Regarding an actual dual-SIM device with both SIMs being CDMA, I'm unsure if it causes any issues, as there's been no phone with that ability released yet (technically, someone can try dual Verizon SIMs in the OP3, but the CDMA implementation on that phone looks to be pretty half-assed, so I wouldn't use it as a baseline). Guess it depends on how the SIM slots are setup (if they share the same IMEI, or if they have different IMEIs for the two slots). If they're the same IMEI, I can see there potentially being issues, but if they're different (which should be the case for any modern name-brand flagship), there shouldn't be.
We'll know more once the Axon 7 releases. Unfortunately, ZTE has said that CDMA support will be coming in a software update later, but at least the phone is physically banded for CDMA, so we won't know for sure until then.
Actually the xt1644 have dual sim slots , one is hidden open the phone and you will find it
Hello, I recently came across a Note 3 tmobile variant online that is unlocked. I know that it is a dual band cell phone and I am looking to use it on my Sprint account. The person I acquired it from says that she used it on Verizon (even after a point when she would not benefit from lying). I am not completely new to flashing phones over from one CDMA carrier to another (prls, msls, mdns, NAM, programming, etc.), nor am I am new to rooting etc. However I am beyond lost when trying to go from TMo to Sprint on a dual band phone. Is this possible? How might I go about accomplishing this? Will I be locked into a specific rom? Any help will be greatly appreciated.
By dual-band, you mean CDMA and gsm?
You can't flash a Sprint ROM into a T-Mobile phone. and you can't convert an n900t to a CDMA.

Yes it has GSM and CDMA from everything I have seen online, additionally in the settings of the phone itself it also offers a choice in connectivity to GSM or CDMA.
I don't have the phone but are you sure it doesn't say wcdma in there n900t?
