I'm in Vietnam for vacation, the GS4 has been released here already.Was wondering if I buy GS4 here can I later flash different modem like att or tmobile US to use on their network?
My main concerns is LTE on att and tmobile.

Most likely LTE will not work so if thats your main concern just get it in the U.S unless you dont mind being on 3g maybe H+

I never had a gsm phone so I dont know alot about world phones. On sprints community foruma there is much debate if the gs4 is a world phone. I see a sim slot my guess that it is. Anyway if I were to switch to tmobile, can this phone be used or is it completely impossible? Other countries use gsm networks only so being a world phone I would assume that it can be used with US gsm networks. Thanks.

It is a world phone but it is locked to Sprint only you can call sprint and have it unlocked for international and sprint simcards only no domestic Sims like from t-mobile and AT&T.

Okay did some research and youre correct. Invalid sim pops up when a local sim is inserted. Lets say I flash the google edition rom stock rooted. Now I know it will mess up all radio with cdma but will this bypass or does sprint have a hardware lock on the device?

Yes, it will work on tmobile for text and call when you unlocked it. For data, you need to change the apn setting to epc.tmobile.com. I am sure that you will get EDGE but not sure about 3g/4g or LTE.

That is not correct. It will work if you unlocked it. You will only get EDGE data for the time being in the US.

sprint to tmobil
thanks for all but can someone put what will be the procedure in how its done and the call how it will work just fine or what? please i need to know to do it im a newbee .thanks to everyone
You can't do it, it is impossible. Sprint has US carriers blocked and there is no method to unlock to use a Sprint phone on Tmobile. So here is the steps to follow: List your Sprint phone on Ebay or Craigslist, Sell it, go buy a Tmobile S4, enjoy.
2nd try

Im having difficulties rooting the S4. When I check it says its not rooted properly. Im still on MF9 and have no clue how to get it to MDC/MDL baseband. Any help? And how would you change the apn settings?

will not work don't waste your time trying. Maybe on verizon or another cdma carrier but not gsm just wont work. I read this question at least 100 times on xda and no one ever did it successfully or even partially. Trade or sell it

There seems to be a very dismissive attitude in this thread.
I have a Sprint HTC One and I can easily throw a T-Mobile SIM in there and get full service (sans LTE) with T-Mobile. The HSPA+ is faster than the Sprint 3G.
So while I do not have personal experience with the S4 in this fashion, I do not see why it would not be possible to get it unlocked and used on T-Mobile. (Unless Samsung/Sprint are blocking it for whatever reason)
Sorry for the "stupid" post (maybe) but I thought the S4 had built in radios that would work with different carriers?
I have a US Cellular S4 but need it to run on a GSM AT&T network. Does anyone know if I can flash the software or what to do to make it work?
Many thanks in advance
I wanted to know what carriers the At&t S4 would work on also. I think it works on T-Mobile but its GSM. Will it work on any other carriers? Is US Cellular GSM?

Hey guys,
Had a couple of questions that maybe some of you could answer... I've got an AT&T sgh-1337 and wanted to trade my dad for his T-Mobile GS4... Since MF3 doesn't allow me to have any fun.
Is it a good idea?
Will I still get the same LTE speeds?
Does anyone know if all T-Mobile GS4's are unlockable (bootloader)?
Thanks.

The t-mobile doesn't have a locked bootloader, I would trade...
LTE will be same.
Can i get a tmo s5 to work on verizon?? I've read a ton of conflicting data and basically was hoping someone would happen to know fa show. Thanks

No. It's the other way around.
Yes, I'm sure that a verizon can work with Tmobile. I looked in network/more settings there was a wcdma option attached to all but one option... i put in the verizon sim and it asks for a unlock code... what if I flashed a verizon rom??

You will have 3g but not sure if the LTE radios wold be enabled for you. I am working the opposite. VZW to ATT.
