SPH-L720? - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I have the S4 SPH-L720 MK2 baseband with a sim card. I'm not sure what that means. Can I use this phone on a different cell company? Or out of the country? Sorry for the noobness. And thanks

After 90 days Sprint will unlock it for international use it can't be unlocked for US use right now as only earlier versions of software have been successfully unlocked

Well...if you have a "sprint" version of the s4, my understanding is that the Sim card is only for the 4g in america on CDMA LTE networks. There really isn't an international OS. And even if you managed to flash certain radios, I don't think, (correct me if I'm wrong), that u can use this phone over seas in europe

That not possible. This is a sprint variant you cant clean it and make it international. Unless you want aosp but still going to be sprint. Unlocking doesnt mean anything just unlocks the phone to use any international carrier. Thats it nothing more.

[Q] Sprint Galaxy S4 with stock 4.3 and MK2 baseband

I just recently acquire myself a Sprint Galaxy S4. It is not rooted. It is running stock android 4.3 with the L720VPUEMK2 baseband. My question is can I unlock this phone to use on US gsm carriers like Tmobile and AT&T? I don't want to buy any unlock code from ebay because those codes only allow it to unlock to use for overseas. Have I had a choice I would've just bought a Tmobile, AT&T or verizon galaxy s4, but they were too expensive. Can anyone help me?
Pls read next time, anyways no you can't as of right now because only works with mdc or mdl basebands and no way to downgrade right now...mf9 and above you can international unlock tho

Darn it!!! So what you're basically saying is that even if I rooted the phone and use a rom that supports MDC or MDL basebands I still can't unlock it to use on domestic GSM carriers? If that's the case if i'm reading correctly then I guess it's time to put up the phone for sale on Swappa.
I think that because you can't downgrade to MDC/MDL baseband you can't unlock it in domestic GSM carrier at least currently.
The knox in bootloader denied you to downgrade to MDC/MDL baseband.
So either wait to get a solution or sell it.

Some users tell that they can downgrade the baseband easly to MDC/MDL baseband only.
so if you can you can unlock GSM.
Note:downgrade the baseband only ....neither the software nor bootloader.

I'm sure you can carrier unlock your S4 and allow you to use another Sim card. Try searching for it

I think you can carrier unlock for 3G data only. But I think Sprint has to give you the code, and you have to be off contract or paid up on your phone.
If you look around you will see the domestic unlock only rolls when you are on mf9 bootloader and can go back to mdc If you are on 4.4.2 the best you can do is foreign unlock after 90 days on Sprint and then they will unlock it.

Which firmware version were you on when he tried? I believe you have to be on an older firmware first like PC5 before it'll work.
Flash your phone to PC5 and try again.

Is the Unlocked 935U model a better buy?

I know some of you guys just flash the "U" firmware, but I want to just buy the phone unlocked. For the ones that just bought the unlocked phone, instead of flashing the "U" firmware, did you notice any problems using the phone on the VZ network? Do updates actually roll out faster?
No problems at all. I had the U model when it first was released and kept alternating between vzw, tmo and U firmware. Everything worked per the appropriate firmware. Moreover,b it's cheaper on BH photo since they don't charge tax as well

Does it have all the same radios as the verizon version?

Go to B&H website there you will find the information.
Thanks!
Did just discover it would be pointless for me because in the future if I want to use it on ringplus it won't work

The answer is NO. The Verizon version is CDMA only.
Nope, I flashed the unlocked version on the verizon model and after a week it started running like ****. Just spend an extra 100$ and buy the unlocked model on swappa and call it a day.

You're kidding right? Every major Verizon phone in the last two years is factory unlocked. I'veused a Verizon LG G3, G4, S6,S7 , and S7 Edge on ATT.
