I recently got a new case, before I put the case on I opend the phone and notice that my galaxy s4 had a sprint ship like t mobile or att. My question is would i be able to unlock the phone to go to another carrier? I also heard that inturnacianal phones are worth more. Before this galaxy s4 i had a galaxy s2 and htc evo 3d and i never had a chip on any of those phones thanks in advance guys.:good:

It's a world phone and can be used on international prepaid networks. I think

The SIM card is removable, and there is an option to set the network to GSM, so I'm assuming it can be done.

Can it be unlocked? It is very likely that it can be. If you're in good standing with Sprint, you could probably call them and tell them that you are going on an international trip and would like to use a prepaid international SIM card, and they would probably unlock it for you.
As far as how it goes with, if the phone is stolen, if you report it as stolen, there is a chance they couldn't use it at all with the new blacklist in place, compared to the old one that only blocked the ESN for CDMA activation.
Sprint sims are locked to device. So say you lose your phone someone else puts their sim in it won't work. If you got a one and a gs4 and want to swap sims that wont work either. If you lose your sim you have to get new one directly from sprint... being so new I have heard these may be difficult to find at the moment.
Not sure how much control sprint has over international sims once unlocked. I suppose that is a risk you take for the freedom.
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...

Methods used to obtain this?
I am I believe sim unlocked because I no longer see the prompt for password apon boot but the verizon doesn't connect.
Thank you in advance!
I need to replace my i337. Will Samsung Galaxy S4 GT-I9500 work on ATT? If so what needs to be done to do it?
Thanks

It will function and make calls, but you will not be able to connect to att's LTE network. The i9500 does not have LTE radios at all, AFAIK. Your best best for connecting to at&t LTE on anything that is not an i337 is either the Canadian(Rogers, etc.) i337M, or you might want to check the T-mobile gs4 forums to see if there is a hack to connect to at&t LTE.

I believe the T-Mobile S4 will work Perfectly on ATT network with NO CHANGES needed. It has all of att's frequencies as well as tmobiles. May just need to add att's apns and Sim card. PLUS its boot loader was not (possibly still not) locked and can flash anything.
I have a AT&T galaxy S4 and would like to put it on Sprint.
do I need to or Can I use a sprint Rom on it? is there anything else I would need to do?

Don't believe there is anyway to do that.
AT&T uses GSM networks while Sprint uses CDMA networks. Two different radios and signals.
Sprint phones sometimes have a SIM slot but that is mostly for LTE. Some Sprint phones can be unlocked to use on AT&T but not vise versa.

if i use the ZTE Z813 that i got for free or basically free when signing up for cricket i always get LTE. when i put my sim in my older Galaxy S4 SGH-I337 16GB AT&T Branded phone (stock rom OC3) i get mostly EDGE. if i reset may data connection i will get LTE for a while but then always seems to revert to EDGE. i get nothing in between. is there some reason why i can get consistent LTE on my Galaxy 4? Could I have some setting wrong? maybe phone is faulty. the light up buttons on bottom no longer work. should i replace S4 with S5? Should I get consistent LTE using S5 on Cricket? Thanks for suggestions.
Does the phone imei have to be registered with cricket?
