[Q] Have a tmob s4 version thinking of moving to Verizon - Verizon Samsung Galaxy S 4

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!

Only the Verizon S4 will work with Verizon, you'll need to go to ATT.

I see others that have used the Verizon s4 on Tmob so not sure why the reverse wouldn't be true... ill research more but I am finding that all the s4 hardware is the same... only software differences.. (possible that its not possible to get the Verizon software on the phone the hardware should be the same)...
maybe get some more input

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.

[Q] Difference between KDDI-stock and Sprint flashed with KDDI radio?

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.

Verizon Samsung Galaxy S4 to have AWS 4 Band (Tmobile LTE Capable?)

Hi,
So I've read the FCC documents located here: LINK
Page 1 and Page 5 are the most interesting! These state that the Verizon model SCH-i545 will have AWS band 4 (of course 13 too) which does support T-mobiles LTE network right? It never states 1700/1200 frequencies.
Thing I want to know from the pros is will this phone indeed offer LTE support for T-Mobile or and I'm just seeing things?
Also, for all the other people that are wondering if the ATT model will offer LTE support for T-Mobile as well? It will since it supports both bands 4 and 17 But wait is that AWS band 4?... the jury is out on that! -_-
Many Thanks

If I am correct, Verizon phones do not use sim cards (CDMA) and AT&T and T-Mobile are GMS (sim phones). So even if the bands are supported, I don't see how a Verizon phone would work on T-Mobile or AT&T unless they are CDMA / GSM dual phones. And even then they would have to be unlocked.

All of the major Verizon releases over the past year have come GSM unlocked. They are world phones that contain GSM and CDMA radios. I'm using a Verizon iPhone 5 on the Straight Talk (AT&T) network currently.
All lte phones have sim cards as it is a gsm technology. My girls verizon gs3 has a sim. As far as it being compatible that is a hell of a question.

Yes! I sold my iPhone 4s to get Samsung galaxy s4 and it sold to someone over in the UK world (Ireland) that says it works! Lol.
I've also seen threads about sim unlocking the Verizon S3 for domestic and international use. Some people use HiAPN as system app along with other steps and viola... Working on whatever network you want
Question is... Am I seeing right that Verizon S4 will support AWS Band 4 for t-mobile?

Hey this is one question i have lingering on my mind. How is the StraightTalk connection? Is it any good? Are there call drop issues? And do they have data plans?
if i buy a tmobile s4 will it work on verizon??
I know most things are under the catagory of speculation/rumor but i was wanting to to check out tmobile network for a bit.... the no contract is appealing. If i bought the phone outright and ending up not liking tmobile i would switch to verizon. Short of selling the tmobile and getting a verizon phone i was wondering about just activating the same phone on verizon?
Will there be "one phone" in US or would they all have thier own modem chips i guess is the real question....
thanks for the guesses and speculat'n!
You have to consider its Verizon and they have 700Mhz LTE and you can't roam on AT&T's 700Mhz so I would not expect to access Verizons AWS spectrum on T-Mobile or vice versa. Remember when they said LTE was the unifying spectrum to allow for easier use across networks and carriers, well that was a pile of BS.
Great news, but I heard verizon was purposely going to burn in their logo onto the amoled screens.

Wrong: those "700mhz" frequencies are different bands. Both T-Mobile and Verizon are building out LTE on the same band: 4 (AWS). They will be interoperable device-wise.
AT&T also owns a lot of AWS, and though they're currently running LTE on it only in one market (somewhere in Oklahoma IIRC), all their LTE devices do come with band 4 enabled.
The more I read about the differences, the more I'm convinced that the Verizon model is more cross compatible with all other services. It's still the only CDMA model. But it's also gsm unlocked if you know how to program APNs. Any thoughts?

if we ever get to the point where we don't need 3g at all any more (CDMA) and we can get VoLTE and use the LTE band exclusively that will eliminate a lot of the incompatability between Verizon and GSM carriers .

When we get to that point, Verizon will basically be a GSM carrier. Considering LTE is just an evolution GSM, both developed by 3GPP.

Not just Google...all the manufacturers could do it. But...don't get your hopes up. That situation is not in the carriers' nor major manufacturers' interests, and they sit on the standards bodies. No one represents the users/customers.

[Q] Groupon S5 Deal: Work on T-Mobile?

Groupon has a deal for the S5 that says it's for "Verizon and GSM Unlocked":
https://www.groupon.com/deals/gg-samsung-galaxy-s5-smartphones
Is there any way to tell what model # this is? I'm guessing that it is a generic S5 and not the T-Mobile specific SM-G900T. If that's true, then it likely doesn't have the TMo specific LTE frequencies needed for full service (I'm in the Chicago area), correct?
I really hate having to find special versions of GSM devices to make full use of T-Mobile's network...
<TAP><TAP> Is this thing on???
Unlocked for all Verizon and GSM carriers.
On the same page --> https://www.groupon.com/pages/groupon-deal-images-gg-gsm-providers
Only thing is that it probably will not be compatible with WiFi calling features, but I could be wrong.
I know it would work but I was curious about whether it was the same model they sell via T-Mobile that has their unique frequency bands (1900/2100 I believe). Groupon responded to an inquiry and said it was a Verizon model so while I can't confirm it, I'm guessing it doesn't have the extra bands needed to fully make use of T-Mobile's LTE network so it would likely drop down to HPDPA+ in many locations.
According to the reviews, its a Verizon branded phone. A couple of the reviews are from T-mo users and they claimed to have issues with the sim/network not going to LTE, instead it uses their HSPA network.
If it was me, I would not buy this. It is cheap yea, but remember that the S5 is not compatible with the new band 12.
-edit-
The Chicago area isn't getting band 12 anyways, not anytime soon that is.
I'm using a Verizon S5 with a T-mobile rom and it works perfect 4g lte and all If you end up getting it just root it then look at my view forum posts.

Will this work? Verizon M8 --> AT&T fo-'official'?

I have an old M8 lying around that I fired up and had remembered I had rooted it and the bootloader is unlocked.. Is there a way to 'trick' this phone into thinking it's an AT&T branded phone? hboot, etc. and that will allow me to RUU something official from AT&T? I know this sounds really strange and probably stupid but.. I just can't sleep and need something to fill the time.. Can I do it?
Don't think so, radio hardware is different, not to mention the partition layout.

Absolutely not. At least not any way that is known; and your chance of failure is high (with a brick being the possible or even probable result).
As mentioned in the previous comment, the partitioning on the phones is different. If you try to run the RUU, you at best it will fail, at worst it will brick the device.
Most other M8 versions (that don't support CDMA) can be "converted" from one version to another (other exceptions being dual SIM and M8 Eye). But Verizon and Sprint are the oddballs here. Some experienced devs have been messing around with these variants from the start (to try to convert them) with no success.
Perfect! All I needed to hear! Ah well.. it was worth a shot! Just trying to get my account provisioned for LTE so I can get LTE on my unlocked devices.. I've been told, and read, that if I can get an AT&T branded LTE capable phone to just swap my SIM in it.. and let my account provision, then I'll have LTE on any device AT&T or not... Just trying to avoid a contract..

As long as the phone is SIM unlocked (Verizon version is) then you should just be able to put an AT&T SIM in, and enter the proper AT&T APN for service, as long as the phone supports the proper bands. Its irrelevant whether the phone is AT&T branded or not.
Now the underlined bit in the paragraph above is the main issue. The Verizon M8 only supports one of the four bands (Bands 2, 5, 4, and 17) used by AT&T for LTE (Verizon M8 supports Bands 3, 4, 7, and 13). So depending on what band is used in your area, you may or may not get LTE.
But GSM (2G) and HSPA (3G) should work just fine on AT&T.

That's the odd part.. My main phone is the S6 Edge from Verizon.. it's on the AT&T network and I assume my APN is correct.. But it's not picking up LTE and I am almost certain the S6 Edge from Verizon will pick up the correct band for AT&T LTE .. But it's only using the H+ speed.. What's even more strange?? When I throw my SIM into the M8? I get LTE on AT&T and verify with 30+mpbs speeds.. I have no idea what's going on...

Yeah, that is strange. According to the specs for the S6 Edge here, the Verizon version supports the same LTE bands as the VZN M8, and actually some additional bands (2 and 5) that also happen to be bands used by AT&T.
One thing I can think of, is that the VZN M8 in actuality supports some bands that are not advertised/explicit in the specs. It wouldn't be unheard of, as members here have reported some versions of the non-CDMA M8 as supporting some bands not indicated in the specs. And that band happens to be what AT&T is using in your market region. In this case, that band would seem to be Band 17 (the only band that AT&T is known to use, that isn't listed on the S6 Edge specs).
Or the other possibility, is there is just some issue with the S6 that is preventing connection to LTE (but on the same supported band that the M8 has).

As I've already mentioned, its not really necessary to have an AT&T branded device. I suspect the reason you've seen people say this, is that AT&T branding means by definition the phone has all the bands used by AT&T for LTE; since obviously the phone is intended for use on AT&T's network. Since AT&T uses a number of bands (4) and LTE bands being used worldwide has become very un-standardized, its somewhat difficult to find a non-AT&T phone that has all the bands. But they do exist, such as the US unlocked M8, Dev Edition M8, and Nexus devices. Also, I've seen folks used other non-ATT branded phones, which may not have all 4 LTE bands used by AT&T, but the one(s) needed in the particular user's region. Not ideal, but sufficient for some folks.
Another reason why some may say the phone needs to be AT&T branded, is that AT&T tech support won't provide you any support if you have a non-ATT phone. But honestly, I've used non-branded devices (and plenty of folks here have), and this is very rarely an issue. The folks here on XDA will usually provide you better support, anyway!
Of course, your ATT account needs to be provisioned for LTE in order to have that service. Its a simple matter, and doesn't cost anything (just need a smartphone data plan).

Absolutely NO.
What I mentioned above (Post #3) for the Verizon variant, also applies to Sprint (both versions support CDMA - the fact you don't use it is irrelevant). If you try to convert to another version won't work, and will probably result in a brick.
Also, even if you didn't have a CDMA version M8, you typically can't convert using an OTA, it has to be an RUU.

Absolutely NOT. As already thoroughly discussed on this thread, if you attempt to install another version's radio on the Verizon version, it won't work, and you may radio brick the phone (permanent damage possible).
Different radios, different partition layout.
Don't even try it. Experienced devs have tried to "convert" by various methods and mods, and failed.
But there may be other ways (besides flashing another version's radio) to enable the band(s) you want, read on:

Unlocked Tmobile Note 8 on Sprint

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.

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?

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?

Sprint won't accept any devices on their network unlocked or not if they came from any other carrier. Sprint only allows Sprint phones and factory unlocked devices. Its Sprint, they suck.

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
