Can an AT&T or T-Mobile S4 be used on Verizon - Galaxy S 4 Q&A, Help & Troubleshooting

I got a Galaxy S4 for AT&T cheap so cheap I just bought to play with. Any way to make it work on my provider verizon? Can I reflash the modem, rom, activate it change the sim or something to make it work? Or should I just turn it in to a small tablet for my son. lol

I dont think u can use that as verizon is CDMA and at&t is gsm

That is correct. CDMA phones and GSM phones are not interchangeable. Neither will work on the other network. If there is nothing wrong with the phone, you could always just sell it on eBay or somewhere, and given the going rate for the S4 now, you should be able to get enough money to buy a Verizon one easily. That would be a very expensive "mini-tablet" for your son. :silly:

Partially true. You can use a Verizon GS3/Note 2/iPhone 5 on GSM with some simple mods. To the |OP|, I would recommend putting it on swappa.com, XDA's official marketplace. Good, honest members are willing to pay top dollar for a clean phone.

I wasn't aware of that - in regards to the GS3/Note 2/iPhone 5. Thanks for clarifying!

If you could do it all over again, what carriers Galaxy tablet would you buy

I have the Verizon one, It works well but that lack of development and inability of it to ever make calls has me ready to move on from it and get a GSM version. Im a bit confused as to which one to get. It seems as if the Att one is the way to go but I dont want to make another $500 mistake. So which one woud you get and why?
Please advise
AT&T version is the USA is the most flexiblr and best if you want to flash and customize because it has the same radio as most Euro versions.

w4, have you done any custom stuff??
The Bell and Rogers Galaxy Tabs are good too since they're the same as the AT&T Tabs.
I have the Bell Tab. No issues at all.
I want to be able to use it as a phone, I see ATT is what is needed but just going in to the ATT store and purchasing a tablet with a month to month plan will I get all I need, after the mods here of course??

if you already have an att phone with voice and data, then yes. Just insert your current sim card.
I'd stick with the verizon one because it works everywhere. Good luck getting anything from AT&T to work in the southeast, for example. AT&T is awful where I live and, in fact, when my AT&T contract is up this summer I will most likely ditch them and the AT&T iPhone for Verizon and their iPhone. Which is another reason I'd stick with Verizon...already have a phone and couldn't care less about making voice calls with a tablet, especially when there are so many options that work just fine on the tablet as it is.

There are ways to use the Verizon tab as a phone...voip and/or sip. Using skype myself, but slightly unhappy with the way that the skype app goes to sleep and doesn't recieve incoming calls after a while.

[Q] Sim card

I just purchased an unlocked galaxy note this evening, which is the first unlocked international phone that i have ever purchased and I just thought of a question that I can't find the answer to. Does the Nkte come with a sim card if not how do I get one for use on AT&T? I hope someone can help with my question.
Thanks,
Wrong section. Ask this on Q section please.
Anyway, if im not mistaken i read some where that u need to purchase the sim and the phone with proper plan (im not att customer). Grand father, use as u want on the go plan etc. Purchase the iphone, sell the phone on ebay n use the sim on your Note.
But u will only get edge from this. No 4g or lte..

Incorrect, you will get 3g and H+ on ATT, not just edge. T-Mobile will only worth with Edge(2g).
The SIM is always associated with the carrier, so you need to get the SIM from the carrier. If you have a active SIM from your old phone on ATT, use that. If you do not want to buy another phone just to activate it, take the Note into the ATT store and they can get you set up. Just get the correct APN information here before you go in, the people in the store are not always trained to program(input the apn) international phones.
If you plan to keep the Note for a contract period (2 years) The best option is for you to buy a iPhone 4S for $200 and re-sell it only for $600. You will make a very nice profit if you keep your ATT plan for the entire 2 years...and if you do not keep the plan, that extra you made will more then pay for your ETF.

Really? Maybe im wrong then. Anyway, what i know is that (by just reading in xda) is that the 3g, 4g and others only applicable with the phone that u had register with att. They have your imei no. Others than that imei no phone, you will end up throtteling and just can use the edge.
Anyway, dont take my word. Better you go to the att center to get the correct info

I had absolutely no problems when I brought my Note into AT&T. They put a new SIM card in and all was good. Just had to put in the correct APN information in and I had 3G and HSPA+. No worries.

Another bad news for Sprint users and ...

another reason to believe that Sprint GN2 may not have SIM slot.
We already know that previously Sprint Photon Q (made by Motorola) have SIM internally and unremovable. Now we know that there is another Sprint device Optimus G (made by LG) that will have the exactly similar design as far as SIM slot goes. (source here)
With the previous picture purposely a leak of Sprint GN2 device showing no SIM slot, this is likely to be a Sprint own evil doing.
And BTW I'm one very pissed about this. I 'll definitely sending a snail mail to Sprint Executive Office about how pissed I'm as a consumer regarding turning an international capable device into useless crap once the device come out. I go to Thailand every year or so to visit family member and when I am there I would definitely want to use SIM there because of the local number I can use. With unremovable SIM this is no longer possible. I'm very disappointed.
That's sucks, although I don't go over seas that much.. It would be nice to have. Tell them you Ben kohn bah and your red shirt friends don't approve of this.

It appears that this is the route they are going now. I wonder why that is? Does using the embedded SIM force you to use a Sprint International plan, for out of country use?
pardon my ignorance, but isn't the "international" version GSM...and sprint's, obviously gonna be CDMA? and as such, no SIM card?
---at least i've always assumed that SIM cards is something GSM phones use, while CDMA phones do not.

You're right, but some CDMA phones have radios that support at least EDGE on GSM so you can still text and make phone calls overseas (and if you unlock, you could run them on Tmo and AT&T).
However, the question is if the radios will even support the EDGE GSM bands... probably not though.

All of Verizon's LTE phones have a SIM card slot and all of their recent phones also have GSM/HSPA radios for global roaming. I believe some can even run on T-Mobile and ATT's frequencies if you are lucky. But LTE will be Verizon only.
would it be possible to flash a Verizon Note 2 to Sprint in order to have one with a SIM card?
There are so much of competition in market, they skipping features users can easily find alternative. Bad for users but too bad for manufactures. They should understand
Not sure if you saw, but someone has figured out how to remove the embedded SIM in the Photon Q and replace it.

Yea, but whose brave soul gonna do that on not even a month old GN2. And that's beside the point. Seriously, to me it seem like it would cost the manufacturor even more to make the SIM embeded than regular one.

I mean how many sprint phones even support GSM EDGE bands?
I don't use Sprint, so I don't know for a fact, but don't their phones usually only run on CDMA (I've only ever heard of Verizon CDMA "world-phones")
I know that the old Touch Pro 2(wm6) and Photon 4G both have dual GSM/CDMA chip in them and they both have SIM slot.
whats the significance in not having a sim card cause it seems like a good thing to me. unless its like tmobile and att network where you can get gsm phones
The significant isn't about whether it have SIM or not. I mean for most people in the US I think we can get by w/o it. I mean it's like once every year or two that people would go outside the country and can make use of it. So it wouldn't be like a final decision whether to get one w/ or w/o SIM. And you are right there are also AT&T and T-mobile. But I can say the for some people it's about the network in their local, while for other it may simply be about not going back to the service they have bad experience with. To me it's about cost, since I'm a Sprint SERO Premium account owner. But very, it's more about why walking the low path? The phone would have been technically capable of it, the chipset, modem, antana support it. This is more about why purposely redesign it to lock it down to a specific network, greed, basically.

Yes, the Sprint HTC Touch Pro 2 most certainly had a SIM card slot. I had a few of them before making the jump to android with my EVO 4G. It was a nice feature to have on a "Business" phone, which is what the TP2 was geared towards. The productivity of the Note 2 also can be geared for Business users, a SIM slot would be of great use.
Ohh okk that makes sense. Cause I never go out of the country so its not that big of a deal for me. But I guess I'd you travel a lot it would be better to have one

Apparently Verizon figured out how to do it properly as they previously have had CDMA, but now allow removable SIM cards for their LTE world-phones. Sprint is now the only provider that locks their phones down like this- it's very frustrating. I am paying for a brand new device that is inherently compatible as a world-phone, but I must buy a separate device to use over seas so that I don't get raped with Sprint's international calling/data plans. RIDICULOUS! These kind of tactics are out of the apple playbook- limit the options of your customers, so you can squeeze em.

[All CDMA Carriers] Before Buying a Nexus 6, Consider Where You Buy It

Just wanted to post a public service here for y'all.
If you're buying a Nexus 6 and plan to activate it on Verizon, Sprint, or US Cellular, you should either buy it from your carrier of choice or from Google Play. Unless Google pulled off a miracle (unlikely), all the CDMA carriers will only have IMEI numbers whitelisted for devices sold from Google Play and devices sold by that carrier.
In other words, if you're planning to skip Google Play and instead buy one from T-Mobile at full price, then walk over to a Verizon store and activate it, it's not going to happen.
Further, if you're buying a Nexus 6 and expect to be able to activate it on any of the 5 supported carriers at the drop of a hat, buy it from Google Play and don't even consider buying it from a carrier.
If you want a more in-depth explanation, I made a video on this.
https://www.youtube.com/watch?v=9cCT_ifWGLs
UPDATE
Now that people are getting their Nexus 6s, we've got some more concrete information. Keep in mind that every Nexus 6 sold in the US supports CDMA. The problem is, unless you buy it from specific places, the carriers' systems won't allow activation.
VERIZON:
Verizon is not officially allowing any Nexus 6 on its network yet, however, that's only through official channels.
If you have an already-active line, you can take your SIM card (cut it down to nano size if necessary), put it into any Nexus 6 (no matter where you bought it), and you're good to go. If you need a new line of service, you'll have to activate using an IMEI number of a display device that takes a nano SIM (I'd recommend an HTC One M8 or a DROID Turbo), then once you get your SIM card, put it in your Nexus 6 and you'll be golden. And no, this is not stealing IMEI numbers. The minute that SIM goes into your Nexus 6, the display model's IMEI number is freed up. There's nothing morally questionable about this method at all.
SPRINT:
Sprint will currently allow devices sold from Google Play, Motorola, Sprint, and AT&T. We aren't sure about devices purchased from T-Mobile, or US Cellular. Since Sprint whitelists devices at network level, your MEID must be in the system in order for your device to actually handshake with the network. The Verizon trick of using an already-activated SIM card won't work for Sprint.
US CELLULAR:
USCC will activate devices that they sell, as well as ones purchased from Google Play. I attempted to activate my AT&T-purchased phone on USCC and the MEID (IMEI minus the last digit) was not in their system, therefore it could not be activated. Since USCC, like Sprint, whitelists devices at a network level, the Verizon trick of using an already-activated SIM card will not work. There is presently no word on whether or not USCC will activate phones purchased from Motorola, but I'd bet the answer is no, at least for now.
Great explanation. Thanks. I'll definitely be buying mine from the Play Store for use on Verizon.

In which case they have to honor it because Google is selling it as compatible with all carriers.... Do you see? There isn't a "verizon" N6. If there was you would have to provide your carrier of choice at checkout. Otherwise the idea that they are comparing IMEIs is bunk.

seems it was the case for the N5. https://community.sprint.com/baw/thread/150262
So it is very likely the same case would happen to the N6.
I planned on buying from the play store anyways.
Thanks for confirming my suspicions.
Honestly, anything at this point is purely speculation. I don't think you can confidently say that buying from t-mobile means your phone won't work on sprint or vzw...
I just hope vzw hasn't done something really dumb and only recognize IMEI numbers sold through THEM (not even google).

Quite the contrary, I understand CDMA well enough to not consider it if it was the last technology left still in use. (Ex Red subscriber). I totally agree that CDMA providers will need to whitelist the imei#. But by the OP's quote that I highlighted he said "any of the 5 supported carriers". Last I checked, 2 of the 5 supported carriers were GSM. (AT&T and T-Mobile in case you didn't know). I specifically was saying that I call BS that a T-Mobile phone would have any issues what-so-ever starting up and working on a AT&T network. So either you'll are misunderstanding me or I am more tired than I thought and have misread the OP in which case my bad...

I'm wondering if the Play Store units are only compatible with TMo and ATT. Look at the way the carriers are listed on that image. TMo and ATT are above the line with the Play Store link. The CDMA carriers are below the line on their own. That can't be an accident.
Alright guys, time out.
Every Nexus 6 sold in the US, no matter where it's purchased from, will technically work on all 5 carriers. The issue is, the CDMA carriers won't have IMEI numbers white listed for stock sold from other carriers. Based on the IMEI number of your phone, I can tell what color it is, how much storage it has, and where it was sold.
You can activate any Nexus 6 purchased anywhere on AT&T or T-Mobile because they're GSM and don't care where it's from.
You cannot buy a device from anywhere and activate it on Verizon, Sprint, or US Cellular, though. You can lie and tell then you bought it from Play but it won't matter. If you purchased your phone anywhere other than Play or the CDMA carrier you're trying to activate with, they won't have your phone's IMEI in their database, thus no activation.
As for devices purchased from Motorola, I'm not going to speculate because I have no history to go on, but I would imagine that those would be OK as well.
T-Mobile and AT&T will take any Nexus 6 sold anywhere.
Verizon will take a Nexus 6 sold from Play or Verizon.
Sprint will take a Nexus 6 sold from Play or Sprint.
US Cellular will take a Nexus 6 sold from Play or US Cellular.
It doesn't matter that your Nexus 6 that you bought at T-Mobile works fine on al the CDMA carriers (and it will). The CDMA carriers will not activate it purely because the phone won't have a whitelisted IMEI number due to the fact that it wasn't purchased from that carrier or Play. It's no more or less complicated than that.

That sounds logical, except its not how the cdma carriers work. The iphone 4s (and now the 6 and 6 plus in the US, though sprint has a different model, but verizon uses the same model as att/tmobile) was the same model for cdma and gsm, but it wouldn't work on cdma networks unless originally purchased from a cdma network. Basically they whitelisted imei numbers to only activate iphones that were orignally purchased on cdma networks even though the model was capable of both gsm/cdma.

I think what a lot of people don't understand is that you can tell by a phones IMEI number where it was purchased, it's color, the storage, and model number. So you're exactly right. The CDMA carriers only whitelist the devices that they sell, and they enforce that via the IMEI number.

The only time I have ever heard of Verizon allowing a non-Verizon or non-Play Store sold device on their network is by someone having an insider connection and white-listing it. I think it's pretty safe to say that if you buy a device from T-mobile, it will not work on Verizon, unless Verizon changes the policy that is has had in place for years.

Taking Sprint S4 to Verizon? Other Carriers?

Greetings, I can't seem to find a definite answer or guide to this. I have a sprint galaxy s4 and once my contract was up I was looking to get off sprint and onto another contract, looking at verizon as my friends happen with them. I know they both use cdma. If I have them unlock the phone, can it be brought over and used that easily? If not, what must I do? Custom root? Find a verizon s4 motherboard with clean esn? I'm willing to do it to not spend a few hundred bucks on a new phone. I'd liketo give it to my mother and get the s6 for myself when it comes out.
Man, I'm 0 for 2 here. Anything?
bump?
Another bump. Can anyone help me?
94 views, not a peep. I thought these forums were active and helpful? Perhaps not?
All of my research leads me to believe I'd need to get a verizon logicboard with a clean esn. Maybe I can trade for one, but I would like some confirmation before I spend the 80 bucks or so. Thanks.

I'm willing to do it to not spend a few hundred bucks on a new phone. I'd liketo give it to my mother and get the s6 for myself when it comes out.

Hello DroidZ,
It is. I was planning to have them unlock it. But I heard that though both are CDMA, I wouldnt have full 4g with it. I was contemplating buying a verizon (or any other carrier's logic board that I would switch to) and sell my sprint board.
Of course I'd need a clean esn right?
Another bump. Does the lack of responses mean it's harder than a logical board swap?
bump again

You can use the Sprint S4 on Verizon, assuming it's possible for you to unlock it from Sprint's network, but LTE will never work. Verizon uses standard LTE frequencies (750 & 1700MHz) while Sprint uses "Extended PCS", i.e. Spark. Totally different technologies.
You'll need a new phone to take full advantage of Verizon infrastructure, which unfortunately means dealing with an encrypted (locked) bootloader.

Greetings,
Does that mean swapping the logic board with a verizon version won't fix the LTE problem? So I'd get normal 4g? I suppose I could try it. Couldnt deal with 3G. I guess I'm asking if there are any parts I could swap out to fix the problem or if I'm just screwed.
Thanks man.

If you have a Sprint phone, you cannot simply purchase a Verizon motherboard and replace the Sprint motherboard with it. Why it won't work is because the design of the two motherboards is sufficiently different that if you tried it the Verizon motherboard wouldn't fit in the midframe.
In simpler language, you're screwed. You need a new phone if you want LTE. Whether that is a new phone from Verizon or a used device off Swappa is irrelevant, so long as the MEID is clear.
Hmm, I didnt know the motherboards were actually different. That sucks, I assumed they were more like computers. Oh well, thanks for the info though, now I know!
Again, thanks a bunch
