Hey guys, I'm getting my hands on my friend's Galaxy S4. He is on an AT&T plan and got then phone from them through an upgrade. I personally prefer Verizon. I was wondering if I could get some help on making his phone work for me. I have a SIM card and everything, currently using a RAZR MAXX. I've done a little looking around, and from what I gathered, the phone is capable of working with verizon, but I'll have to load a different kernel and ROM onto it. I've looked through http://forum.xda-developers.com/showthread.php?t=2295557 that thread and found some nice info, but I'm not yet confident enough in my knowledge to go through with it. I've decided on the http://forum.xda-developers.com/showthread.php?t=2305781 CLEANROM 1.6.5, but I don't know what else I'm going to need to have in order to make this phone work for me. I also don't know if I'll need to download the Verizion or the AT&T version of this. Thanks for all the help, I'm really wanting to make this work for me so I can actually get a powerhouse of a phone.

Your link is to a thread regarding other variants of S4 roms. Although you can use other S4 roms on the i337, the phone wont work on verizon carrier.

I'm not sure about that. ROM shouldn't matter too much, you just have to have it SIM unlocked and I believe it won't work too well due to the different frequencies between carriers and so you may not get LTE or something. Maybe someone can correct me though.

Verizon/Sprint phones use CDMA.
ATT/T-Mobile use GSM
I don't think you can use a CDMA phone on a GSM network and vice versa.
EDIT:
Per the replies below, it looks like it ispossible.
Here is a thread from the Verizon forums.
Also, if this WIKI page is correct, the Verizon S4 has both CDMA and GSM radio's where the ATT S4 only has a GSM radio.
The first thing to identify on the phone is whether or not it is on the stock AT&T ROM and what version that ROM is. If it is I337UCUAMF3 then changing the bootloader/kernal/rom is not even an option to begin with which means there would be no way to change out the modem to support other carrier bands (such as those used by Verizon). On top of that, although I have heard that the modem hardware is the same on all versions of the S4 I have not heard anyone confirm that they have successfully enabled CDMA services on the I337.

There are some that work on other networks without the need for modem changes. I read about some using the Verizon on AT&T, and I used the droid Bionic, a Verizon exclusive with a locked boot loader, on AT&T.

The strange thing is you can use a Verizon S4 on AT&T but you can't do it the other way around. Verizon phones all come unlocked, allowing you to use the phone anywhere around the world.
The AT&T S4 does not contain the CDMA chip allowing you to use it on the Verizon network, plus it has to do something with IMEI. If you give the IMEI to Verizon, they won't be able to locate which device you are trying to activate because it's not in the system. But if you use a Verizon S4 and put in a AT&T SIM card, you don't have to register the IMEI with AT&T or T-Mobile.

I can confirm that this is true about the verizon s4. I have a Verizon s4 and have used AT&T and straight talk on it. My brother uses that phone daily on his AT&T account.
I will test my AT&T s4 when I get around to finding my sim card.

I'm pretty sure you won't be able to use an AT&T S4 on Verizon because the AT&T S4 doesn't have the CDMA capabilities.

Yea I noticed that the ATT S4 doesn't have everything that the Verizon S4 has in the service menu. Like I can turn on all the different bands in the service menu, but on my ATT S4 I get restrictions on wcdma.
I'm new to all this. I traded a iPhone for the ATT version because I couldn't figure out how to make the Verizon version work on straight talk..
Not two days after I have the ATT I somehow got it working... Lol. So now I have two with unlocked bootloaders and sum unlocked...

I'm sorry to have to disagree with this but I own a blackberry 9630 world phone from sprint and the sim slot works both with at&t as well as tmo. I understand ad long as contract is fulfilled and any etf's are paid Sprint will unlock sim slot and it will work with any carrier, gsm and CDMA alike. Check Sprint forums and speak with cs agents... :good:

Try using an Att/T-Mobile sim on an s4. It will be blocked even if the phone has been unlocked. Previous phones from sprint did not block USA native gsm but as of lately they do.
My good ol htc touch pro was a lucky one to work on USA gsm as of course your old black Berry.
You get it now? Its an accepted fact sprint has been going out of their way to block USA native gsm access on their latest phones. Perhaps some new ones aren't but the s4 is unless a work around is done but it doesn't work for everyone.

This isn't entirely true. I unlocked my Sprint HTC One to run on aio wireless which is on the ATT network. I haven't unlocked my Galaxy S4 but I intend on giving it a shot.
Call sprint and ask for a subsidy unlock code.
You'll need to provide the IMEI
*#06# on the keypad. After they give you the code, try a gsm sim. Hope this helps.

I think I've read about people unlocking for use on metro pcs which is tmobile. Thanks for heads up though, probably gonna have to buy one when I switch.
I unlocked a Sprint s4 and I am able to make calls with a AT&T micro sim in but cannot get data and texts working. I had to downgrade the baseband to get into hidden menu, but I stopped there. In the hidden menu you have to make some changes but I was scared that if I got it to work on at&t I wouldnt be able to get it back working on Sprint. Everyone does say that Sprint doesnt allow anyone to use other domestic carriers.

I broke my sprint phone, but I can upgrade to a new phone now on Sprint. I want to use the Sprint One Up Plan for a bit, then leave the contract since I don't believe it has a contract. I plan on using the G2 as my replacement. I want to move to T-Mobile later, and I know the G2 can be used on Sprint. I also have read here that the G2 comes factory locked by Sprint, and Sprint will one unlock it for international use. Is there something that I could flash to the G2 to allow me to use it on T-Mobile when I switch?
Basically, how can I use domestic USA GSM on a Sprint LG G2?
I will at least root and unlock the phone internationally first anyway, since I need to use outside of the country. Flashing ROMs and things like that is not a problem for me.

Is it possible, after I finish with Sprint, I could flash the firmware and modem of T-Mobile's G2?
Would any of those unlock codes for the IMEI work, since it supports GSM?
Thats risky due to the fact that tmo uses different bands than sprint plus the radio waves are different and sprint is gsm and tmo is cdma

Anyway, I know the G2 supports all of the bands, so I don't see why this can't happen. Sprint has just locked away the domestic GSM capabilities. Why is flashing theT-Mobile modem such a risk then? WOuld I be able to flash it back?

Sorry always get that bavkwards the issue is with two things the radio, which you said you could flash the modem no problem. Then the biggest issue is the sim card now im not sure if the sprint variant has a sim card slot. But from what my buddy has told me who is a tmobile phone tech they dont have away to enable your service with out the sim card. For some reason they dont do their services like most carriers and just use the phones imei number to set service. If im wrong im sorry and hopefully you can get everything switched. And thank you for the imformation i did not know the g2 has all bands hidden inside the phone. I was just worried that the radio bands would get you. And to answer your question yes you can always just flash them back.

No problem. If I helped give me my first thank you. I'm going to go to the Sprint Store soon and see what they say. The Nexus 5 seems to be compatible with any carrier, but I like the G2 just a bit better. Sprint has a help topic regarding replacing the SIM , so that is not an issue. Hopefully someone else can tell me if the G2 can have a different modem flashed.
I don't want to take any unneccessary risks flashing, because that is what broke my last two Sprint phones lol.

Ok so i was wrong it looks like the spring g2 does have a sim spot so all you have to do is 1 get unlock.from sprint 2 flash required firmware and modem and radio files 3 go tothe phones dailer and dail*#*#4636#*#*. This will bring up the menu shown inscreen shot. Switch your current band from evdo to what is shown in the screen shot and bam sprint branded tmo phone if i help at all pls return the favor with the thanks.

It will not work.. Sprint doesn't unlock the phone for domestic US GSM carriers and the 2 models for Sprint and T-Mobile are completely different. You flash anything like the radios and you'll have a massive brick. If you want to move between carriers, get the Nexus 5.

You will not get domestic GSM service with Sprint atm. Hang it up until a solution if any will come. Even after that, it will never be fully compatible with Tmob bands. I love/hate Verizon.

If it supports the LTE bands that TMO uses, then go for it.
Check out gsmarena or some other sites to compare which LTE bands it supports and for which bands TMO is using.
But its quite likely it does NOT support all LTE bands, if any.
i dont think it can
unlocking it only lets you use it internationally

I tried putting my SIM card in, says Not Valid SIM. I'm guessing i could probably get around that somehow but i don't know if all the LTE bands are supported. I'm busy with work but if i somehow figure it out i will post something. But i guess i should start with the radio's as suggested.
I have been doing research and searching these forums for a few days now, I'm trying to not be one of those people who ask questions that have been answered. But at this point I'm at the end of the road.
I bought a Sprint Galaxy S4, model SPH-L720.
I unlocked it using this method Sprint Galaxy S IV SPH-L720 SIM Unlock Method
Reverted back to MDC baseband and all that good stuff, just as instructed. It seemed to have went well without a hitch.
My question now is:
I want to buy one of these Verizon 4G Sim Activation Kits from walmart
Is it possible that I can buy one of those, insert the SIM into my unlocked Sprint S4, and have a working phone? I ask because I don't want to drop $50 if it doesn't have a chance of working. The instructions for this say that it will work with a VERIZON S4, but since my SPRINT S4 is unlocked, should that be okay?
I don't know much, but in my reading I found that Sprint and Verizon both use CDMA, not GSM. So I figured I had a better chance of this phone working if I go with Verizon because of this.
I am in the United States.
If you need any other information or screen shots please let me know, thank you for taking the time to help me out!!
EDIT: would it be possible to test it out, if one of my friends has a verizon phone under contract, and I took their SIM and inserted it into my phone?
Try it.
Like the guy above me said. Try it. One way to find out. Personally I don't think it would work. As the whole point of unlocking the sprint Gs4 is to use it on GSM networks. From what I know you have to flash the sprint phone to Verizon. Plus you WONT get LTE on Verizon because the bands are not supported. So you'll only get 3g.

thank you for the info! i'm just learning about all of this, so i don't have a firm grip on everything yet.
in the tutorial i used and linked above, the file I used with Odin was actually titled "S4 Flasher", so I believe I unlocked it and flashed it with this? Again, Im sorry, Ive tried searching and am just looking for verification if Im correct.
I'm not worried about LTE, 3G is fine really. Also, I'm not set on Verizon, I just want my phone to work, doesn't matter what network I'm using. If it would be "safer" or a better bet to get into a GSM prepaid, I will do that instead. I was just under the assumption (incorrectly probably lol) that since sprint is CDMA, that going to another CDMA carrier would be easier.
Cricket, Net10, StraightTalk, and AT&T etc are all available at the store I think if I go GSM
Again thanks for taking the time to help everyone!

I was just under the assumption (incorrectly probably lol) that since sprint is CDMA, that going to another CDMA carrier would be easier.
Cricket, Net10, StraightTalk, and AT&T etc are all available at the store I think if I go GSM
Again thanks for taking the time to help everyone!

I unlocked my sprint GS4 and went to Cricket. And I've been happier than when i was with Sprint (service wise). I have signal in 98% of the places I go to. Which is a HUGE improvement over sprint. And even though this phone only connects to HSPA+ which is capped at 3.5 Mbps its plenty fast for all my daily activities. So I recommend a GSM prepaid.
Hi guys, new here. Used the place a lot when i needed help, then decided to make a account.
Anyway, i couldnt find a Straight Talk galaxy s4 specific forum so i figured the main s4 forum is where i should post this.
I have 2 Straight talk galaxy s4's i bought new, and im currently in cricket. Well i need to replace my old CDMA s4 with a new GSM one. The straight talk s4's i got are the ATT tower versions. Now, when i put a att or gsm cricket sim in, they say invalid sim. But read att sims fine. If i put the straight talk or gsm cricket sim in a att phone.. Theyre read fine. Which i dont understand. So my question is, can i flash a ATT stock touchwiz rom to them via odin to make them read the att and cricket sim's? Id just try it but dont want to brick them, figured i would ask first in case somebody already tried.
Both phones are identical. Specs are:
16gb black Straight talk galaxy s4
Model No: SM-S975L(GP)
Android 4.3
Touchwiz, un rooted, brand new barely even been powered on.
Thanks!
Current Straight Talk S4 units use T-Mobile towers, not AT&T. Flashing a new ROM won't make them read the SIM cards you're trying to use, and for the Straight Talk S4 will likely hard brick it. Your phones need to be carrier unlocked, which only Straight Talk, at their discretion, can do. As multiple users here have discovered, purchasing an unlock code does not permanently unlock the S4 and half the time doesn't even work.
