Will my Verizon s4 take an AT&T sim? - Verizon Samsung Galaxy S 4

I'm contemplating switching to Straight Talk and naturally I want to keep my S4 versus getting one of their phones..is this possible to just buy the AT&T GSM sim from them and use it with my Verizon s4? Or am I doomed to a Straight Talk phone.

I use straight talk (using there at&t version) and it works perfectly. The only thing I heard was if using at&t it might bump you to 2g phone in the states, but I don't think that's true for S4 like in previous models. But I'm not 100% sure.

Did you ever get this to work? If so what steps need to be taken?
Any information would be appreciated.

Check out this thread. Looks like it can be done but it's time consuming:

Can you switch sim cards on Verizon network?

So if your rooted and unlocked can you simply switch a Verizon sim card for a Verizon sim card? Like my wife's unlimited data razr sim in place of mine?

I'd say yes. When I got the note, I just pulled the sim from my rezound and put it in the note (had to cut it down to size first). No need to call Verizon for anything.
Yes I did that stock with no problems before I unlocked

Another yes here. Pull the sim out of my galaxy nexus into the note 2 and had no issue. Even updated my account on Verizon within about 5 minutes

This is cool. One thing I always liked on gsm carriers is the ability to swap phones whenever I wanted and as much as I wanted (work phone/play phone). What would really be cool is if could put my Verizon sim in my unlocked nexus 4.........
What if the Verizon note 2 had a bad esn? Would it still work I see a lot of deals on ebay for around 4 hundred!

Nope, once it has a bad enough it can't connect to the network anymore, those aren't worth 400.
Edit: I'm not sure if you can unlock it and put it on another network, but it won't work on Verizon.

AT&T Sim Cards are back w/Straight Talk!

Is there a way I can get my Verizon S4 to work with a Straight Talk AT&T SIM card?! Please say yes, so I can get rid of this expensive A$$ bill?!

Yes I'm using my at&t straight talk sim on the verizon s4 and it works great!
Is there anything special I have to do with my phone? When I order the sim card from straight talk it won't let me select the cdma option so, should I just select gsm as if I have a AT&T Galaxy S4?

CDMA does not use SIM cards. The S4 is a CDMA/GSM/LTE device. AT&T is a GSM network.
You might have to edit the APN settings to use Straight Talk.

The Verizon S4 is a CDMA phone AND a GSM phone. I believe they made it this way so you can go to about any other country in the world and still use your phone - or it was just cheaper to mass produce the radios with everything in it.
Anyway the only thing to change is the APN settings to
Name=Straight Talk
APN=att.mvno
Proxy=proxy.mvno.tracfone.com
Port=80
MMSC=http://mmsc.cingular.com
MMS proxy=mms2.tracfone.com
works perfect. However I did just find a small problem. I have flashed both cyanogenmod and Liquidsmooth AOSP ROMS and they do not work with at&t ST sim - when I call the phone it does not answer or register the call at all. Not sure what the problem is, seems like for some reason it is not registering with the at&t network. Trying to find a fix. However, the phone has worked fine with all TW based ROMS I've tried.
Ok thanks for the information but I have one more question... I am rooted with Clean Rom 1.5, do I have to unroot my phone? Will I still be able use wife tether or foxfi? I heard AT&T took foxfi away.

Oops just saw that you messaged me - yes just choose GSM. You do not have to unroot your phone but like I said in the last post - I cannot get AOSP roms to receive or make calls - data works - but not phone calls - which is rather strange and I'm sure can be fixed but nothing I have tried seems to work.
GSM is fine but in reality once you get the right LTE bands turned on, would it be better in global?

What kind of data do you see on AT&T? HSPA+? 3G? 2G?

You shouldn't need to flash to Straight Talk as the Verizon S4 already has an unlocked SIM slot and compatible radios with AT&T and T-Mobile (re-farmed markets) 3G. All you need to do is order a SIM card from them and then enter the APN information for Straight Talk and set the phone for GSM mode. The AT&T SIM card is probably a better choice since some T-Mobile markets still only use AWS for 3G which the Verizon S4 does not support.

ROOT / SU Question / Mega 6.3 / USA / AT&T

Anyone,
I'm not an android noob, but I left Android a few years back (2.3.3 / 2.3.4) due to work changing to iPhones for data encryption reasons. I came back to Android when more Samsung phones started supporting ODE (on device encryption). I would like to root my phone and have done so on other Android phone's using SuperOneClick, CWM, etc.
I am reading that there is a secure boot loader on the AT&T version of this phone in USA, so I am screwed in gaining root access to the device? I'd really like to delete all this bull**** bloatware they've installed... and a tethering app without using the carrier option.
Can anyone help?
I have the AT&T version as well. I'm not 100% sure that the bootloader is the reason for no root yet. Other phones have locked bootloaders and can still be rooted.
Running custom roms might be another story. I get the impression that because this is not a "mainstream" phone that it does not get top priority. For example, the Moto X on AT&T has a locked bootloader and that's rooted already, but it's a very popular phone.
Hopefully we'll get some love sooner rather than later. I would be happy with root along with an easy way to go back to stock.

No boot loader unlock, no root, so no custom ROMs as yet.
Be patient.

I purchased the Straight Talk kit yesterday and you have the option of use Tmobile or AT&T by switching the sim card. if your bill it too high try Straight Talk.
Thx I thought about it but have 2 phones my second one is a s blaze but not unlocked so that person would lose out on service which is needed.

Does straight talk get lte on the at&t galaxy mega and is the upload and download speeds fast ? I have mines unlocked and wanted to know if I should jump ship from at&t and save money and go with straight talk?

Why do people get this phone to use abroad?

I don't get it, I keep setting people asking questions in here about international use when they obviously got it with no intention of ever using it on Verizon, what makes this phone so great that foreigners and even people on other us carriers get it instead of the s4 that's meant for them?
Sent from my SCH-I545 using xda app-developers app
Because they are crazy, cause we are locked down tighter then a baby pig sucking tit in the mourning b4 eating slop in a farm ..... Lucky I have mdk Im pretty pleased with this phone , but if I was them I would maybe buy the phone from a carrier with not such a locked down bootloader
hyperdrive powered s4
probably because verizon has one of the biggest customer base and best service whitch means more phones to be able to buy used on ebay and what not that is just what i think...and i think verizon enabled international on the note 2 and now s4 not sure about the n3 but not sure if other carriers have that option or if it is a gsm cdma difference.. or what or international carriers can only use vzw baseband

Verizon comes unlocked default and uses a cdma network + sim card
Which means it can be used on other cdma carriers around the world+gsm carriers
No other variants of gs4 can do this

Sounds reasonable, but I didn't know there were foreign CDMA carriers
