Just wondering, because I have a Japanese model. I was originally quite fine with using GSM providers, however, now I've moved to a place where Verizon performs significantly better than AT&T and there aren't any other choices as far as I can see (MVNOs aside, but the problem I have with AT&T is with signal, and an MVNO isn't going to help with that). Now I want to switch to Verizon, and I'm wondering if the advice provided to the others with KDDI radios on Sprint Photons would also be the same for a plain old KDDI Photon.
verizon uses cdma and keeps a database of their cdma phones. Thus they dont allow phones on their network that arent already in their database (i.e. they wont allow non-verizon phones). Sprint is the same way.
The only caveat to this is roaming. They will allow non-verizon phones to roam their network as part of roaming agreements with other carriers. You just wont be able to use verizon as your carrier.
OK, then what of a Verizon MVNO, like Page Plus? That seems like it should be OK, from some of what I've read, as long as no one's blacklisted my phone's MEID (it's my first time bringing it to the US, so that shouldn't be an issue).

Although pageplus does allow "bring your own phone", I dont know if they accept non-verizon phones. you will have to ask them.

Page plus will take anything, sprint phones, verizon phones, any cdma phone for the most part that arent blacklisted. Might even take blacklisted sprint phones, just no blacklisted verizon phones.
Ooh, sounds good. In that case it seems like I just need to figure out how to flash in the right settings. All I remember is that someone else wrote in one of the KDDI radio threads that data doesn't work, but voice+text does.

Sorry for asking stupid question....
I did some research, but I still can't figure out why DNA can't uses other CDMA network.
Is it the problem if radio???
According what I see, DNA is able to unlock bootloader, s-off, root.
What stuff should I waiting for? Radio?
Your answer will help me know what kind of threads I should pay attention to. Thanks a LOT in advanced!
BTW, I am planning use DNA in Taiwan with a CDMA network provider.
I had checked the hardware is fitted to my network (CDMA2000 800Mhz). Thanks for all concerned!

Hi,
First of all, you must understand that GSM & CDMA are dissimilar technologies, whereas with GSM you can easily swap between carriers so long as they have the same/supported radio frequencies and your phone is sim-unlocked, this is not possible with CDMA. CDMA devices do not use a sim card to retain your account information or activation abilities. When it comes to CDMA (from my understanding) the ESN is key, the ESN must be added to your networks (for lack of a better term at the moment) ESN database. In the United States, most CDMA carriers will not add ESN's of other carriers phones to their network, your results may be different, because of your location. If your carrier were to allow or be willing to add the ESN of the DNA you obtain to their database than there is a possibility that it may work. (I am unsure if that can just be done or if it would have to be removed from Verizon's network & so forth, because I've never personally had to do such a thing)
There is a second problem though, the LTE radio / sim card interface. Because of the way these phones work on Verizon with LTE, I am unsure if you could even activate it, because it looks like the LTE sim is needed to authenticate your account to the carrier like a regular GSM phone. I have no idea how you would activate this phone without LTE / GSM on your carrier, even with the CDMA ESN added. It seems like it would be a double edged sword, but I could be wrong in this respect.
Also at this current time, this phone has root, and an unlocked bootloader through HTCDev, but is still **S-ON**.
Though none of those things have to do with you being able to use this phone on your carrier.
If your carrier was GSM I would say go for it because this is a GSM Global phone as well, but because its CDMA that you need I really incredibly doubt you'll be able to use this phone, but I may be wrong, but until someone else states otherwise I would look for a different phone.
Hope this Helps!
I am also interested in it. How can we check it out? I should go to my CDMA carrier and ask to activate my ESN?
Where can i find ESN? In Settings-About there is only MEID, IMEI, Phone serial number and IMSIAdded
I work for a CDMA carrier in the USA and with lte on the phones now, they truly act as gsm phones. If your CDMA carrier has lte then they can give you a sim and it will activate your DNA. However, if they only operate on 2g/3g then the post above me is correct with the ESN database and will USUALLY not activate the phone (in store sales reps usually don't even have the ability). Even if they have lte, activating another carrier's phone is not in the best interest of the sales Rep and they usually won't.
YMMV

I should mentions that we don't have LTE in Taiwan so far.
My carrier provides CDMA2000 1xEV-DO rev.B (I guess it is)
Is it operate as LTE OR 2G/3G you mentioned?

From my experience, they will not be able to activate it if they do not have lte, as they would need to have a settings file made for that phone to get it to work on their network. Nevers hurts to call and ask though.

Hi,i am from Austria,i have a Droid Dna by Verizon and the Phone works fine here in Austria, 2G and 3G/HSDPA
Long story short my work has offered me cell phone service but they only have Verizon or ATT.
I have a tmob s4 ... rooted and custom rom. Are the phones "essentially" the same so with a kernel and modem would I be good on Verizon?
Any caveats to be concerned with? its been probably 8 years since I had a Verizon plan but it does offer better coverage than ATT in the places I need...
thansks!

I don't know where you're researching, but the S4 definitely has hardware differences.
Verizon is what's called a "CDMA" carrier. Their S4 includes hardware that can connect to both their CDMA and others' GSM networks.
T-Mobile has a GSM network. Their S4 includes only the GSM hardware, there is no possibility of using it with a CDMA carrier.
Most variations of the S4 also have slightly different sets of "bands" that they can connect to, so the speed you get will vary depending on both the network type and your S4's type. However, the S4 should be able to get at least 2G on any GSM network. Verizon's S4 has the widest possible area of use, because it includes both CDMA and GSM. It can be used on T-Mobile or ATT, but their S4s cannot be used on Verizon entirely because of the hardware differences.

I understand the networks are different.. what I am seeing is that the hardware is the same ... they all have the same chips.. the different carriers are just using software to use what they need
for example here:
http://forum.xda-developers.com/showpost.php?p=25953096&postcount=13
and this thread has examples of people who have used their Verizon on Tmob (voice, wifi, and 4g)
http://forum.xda-developers.com/showthread.php?t=2331131
long story short they say all the phones are the same... they just use different Radio software (plus kernel I assume)
The answer is simple: You will never use a T-Mobile S4 on Verizon.
Verizon S4 on T-Mobile is completely irrelevant, because they're designed to work that way.

There is NO CDMA radio in a T-Mobile GS4.
Even if it were, Verizon will not add foreign IMEID/ESN to their database. Without the IMEID/ESN added to the database you cannot get voice service. You could possibly take a provisioned SIM and get data only, but what good is that.
Sell the S4, buy an HTC M8 do S-Off, move on.
Your S4 will never work on Verizon.
There was a thread about this but it just kind of died without any answers. I know the complication with this is that Verizon is CDMA. I was talking with a friend that's a Verizon cell site tech, and he said that all the new sites and small cells are LTE bands 13,4,2 only... no CDMA. Of those 3 bands, the tmobile has 4 and 2. Some, I have read, are able to use their Verizon v10 on tmobile. So I'm wondering, with the fact that the new sites and small cells around me only uses LTE and not CDMA, am I able to use a tmobile v10 on Verizon? Has anyone tried it?

I will soon be testing this. Bought a unlocked tmobile v10 off swappa...gonna try it with my Tmobile prepaid sim to see if I can actually use their service in my apartment....then will try my active VZW sim. According to spec pages i have read, should have the correct bands for LTE for vzw.
Sorta worked. The t-mobile V10 recognized the VZW number and sim. Calls worked (disable Wifi calling and volte). I had to add VZW APN settings, and it connected, and recognized Verizon network, but I could not get a internet connection. Not sure if i had the wrong apn settings or not.
how were you able to edit the apn settings? when i try i get an error, i've unlocked, rooted, deleted the telephony.db nothing seems to work.
Asking cause a few months back I tried a T-Mobile LG G6 on Verizon and it wouldn't work. Called Verizon and they said it needs to be a Verizon phone in order for it too work.
Wanted to get opinions cause I have a line on a good deal but don't wanna buy a brick.
It won't have CDMA, and for LTE you'll probably have to put in an already activated Verizon SIM card.
Sent from my carrier unlocked LG V30+
The problem is, as above, it doesn't have CDMA. So you would be relying on VoLTE.
Further, the T-Mobile variant doesn't (officially) support band 13; if you ever stray too far from cities, you're pretty much screwed as that's their extended-range band.
If you could get VoLTE working and if it doesn't refuse to work due to the phone IMEI not being recognized/supported (probably checked, because older devices don't support VoLTE), and if you stay urban...yes, it might work. But it'd be far from ideal.
You really need either the Verizon variant, US Cellular's variant or the carrier-less/open market variant. The latter two will technically work with whatever carrier you want, the first and last ones will be whitelisted in Verizon's system unless they decide to be douchebags about it, which would be very un-Verizon. /sarcasm
I'm not sure about the US Cellular one being whitelisted on Verizon. I'm pretty sure USC roams onto other networks, but actually activating it might prove to be a chore. At worst, you could swap a pre-activated SIM into it and be good to go.
I have been reading a lot of different things about doing this with no definitive answer. It looks like, as of recently, it should be as simple as popping in the sprint Sim card and it should work but I want to be sure before hand. Are there any downsides at all about using tmobile Note 8 on Sprint?
Hi there, I'm not sure but Sprint SIM cards are lock. You can try and see, I had Sprint before and try using there SIM card in my unlock tmobile Galaxy S7 Edge running the unlock S7 Edge firmware, it keep reconfiguring over and over. Maybe you might get better than me.

Sprint doesn't allow other carriers phones on their network. Unlocked or not. T-Mobile does though...

First question would be: Does Sprint allow to use their SIM cards within non-Sprint devices? That I can't answer. Because I never used Sprint services.
The second question is: Would the T-Mobile radios work with Sprint? LTE radios would most likely work if Sprint allows you to use their SIM card with that device. When LTE is weak or not available the answer is: No. The active radios within T-Mobile and even AT&T Samsung Galaxy Note 8 are both LTE and GSM (Both 3G and 4G). Both Sprint and Verizon uses LTE and CDMA (each has their own CDMA) radios. You can't use GSM radios with Sprint and Verizon right now. Though that will end up changing as CDMA gets phased out.
To top things off each GSM carrier maybe using different frequencies with some (but not all) of their GSM radios. So changing a cellular device from a GSM carrier to another GSM carrier may have limits with GSM services.
Sprint and Verizon services have problems with international areas (outside of the USA) where LTE is weak or no LTE. The reason is that CDMA is very limit or doesn't exist in most international areas (outside of the USA). The areas that CDMA still works internationally (outside of the USA) will be phased out (mostly in the near future). Only a few places outside of the USA, like China, would CDMA not be phased out so quickly. But CDMA will end up completing phased out all together sometime in future (including in the US).
If you want to be truly Global then go for carriers that have both GSM and LTE, like T-Mobile, AT&T, etc. Then once you unlock the SIM then you can use your carrier's roaming (which don't need SIM unlock) or switch the SIM card with a carrier in that country to get service internationally. Just a side note: T-Mobile does have Unlimited 3G international roaming without any extra cost (this is subject to the type of plan you have with T-Mobile).
The only way this would work for you is if the CDMA radio is built into all Note 8 devices. If so then you just need to flash the correct radio firmware to active the correct carrier radios. But I don't believe this is the case. And this wouldn't solve the Sprint SIM lock issue.
The short answer is no. Read this thread. I thought you could just pop in an activated SIM, but it's not that simple.

ALL US Note 8s (N950U and N950U1) are identical. Same radios. Same hardware. Same everything. Only difference is the preloaded firmware. I actually think the Canadian Note 8s (N950W are the same, too, sonce they can run the N950U firmware).
So it's not an issue of missing a CDMA radio. It's an issue that Sprint will not accept the IMEI for another carrier branded Note 8 (or S8/+). You can only activate Sprint or Factory Unlocked devices on Sprint.
As Note 8 has both GSM and CDMA capabilities, why shouldn't an unlock T-Mobile work with Sprint?

On Sprints website it still does not list the tmo note 8 as compatible for BYOD. It says only the note 8 special edition is. However it is not unlikely they stopped blocking the other U.S. carrier versions. People have gotten devices to activate in the past, but with minimal network functionality. Is your Note 8 fully utilizing the LTE network?
Either way this thread brings trouble so its now closed
Sprint allows sprint capable devices such as clean sprint,Boost and such and subsidiaries that run on sprint only.
@cp1024 @Gizmoe
The Special Edition devices are the ones sold directly by Samsung as factory-unlocked models. Samsung over the years has used the term inconsistently across their site and marketing materials.
Only Sprint calls them "Special Edition", otherwise they are the U1 models, vs U for carrier branded.
Which means they as of the time this was printed will only accept this model
Maybe some others have managed to pull something off but this is official answer
my post above is how it has always been in the past
And it ends here
