There is currently no GSM sim unlock for the SPH L720 for GSM carriers like AT&T, T-Mobile, and straight talk. So how did you sim unlock it? Or do you have a different model of the S4 and not know it? Thanks because if we know how you sim unlocked it we could test the method then help you with your data issues. Also try adding a straight talk apn to see if that fixes the data issue.

I would personally stay away from Straight Talk. Had them for 6 months, worst service I've ever had. They really did suck... And they throttle you hardcore. Honestly they are the reason I switched to Sprint. Also Straight Talk is a GSM network. Not really sure if they support CDMA, I know it was in talks a few months ago.
Straight talk pulls of Verizon as well the iPhone 5 through them runs on Verizon. You can flash the hones over but it requires a imei switch on the device which is extremely illegal.

Is your Sprint L720 GSM unlock? as Straight Talk cannot support CDMA device?
From my understanding straight talk has deals with every major carrier. My mom had a st lg that was pretty much a boost phone.

Of course st has cdma thats the only the way the op could be using it.
They use sprint and vzw too. If you look at bottom of a phone box it will have a S for sprint and a V for Verizon.
Isn't it just great that the O.P with 1 post has stayed mum on folks asking how he got his Sprint S4 on Straighttalk (and which carrier specifically)?
Yes, Straighttalk resells from the 4 major carriers, AT&T/T-Mobile being GSM and Verizon/Sprint being CDMA.
I call B.S on this guy.

why call bs? he used a st donor phone and modified his imei just like everyone is doing for other prepaid options.
Verizon s4 straight talk
THIS IS THE REAL DEAL it's called cloning a phone....FACT: Verizon has faster 3g then Sprint... FACT: $45 prepaid is as cheap as you go... Still a Samsung Sprint phone so flash away! Paid $389 bad esn MINT for my S4 and flashed it for $75. Mine is still in the mail but the flasher has been answering all my questions.
It was BS when he said straight talk carriers all four major providers Straight Talk is GSM and only carries T-Mobile and they used to carry AT&T Sims FACT.
Yes you can do a MEID swap not a IMEI swap (both are very very illegal this phone can't be imei swamped only meid swapped) because the Sim lock on this phone is integrated in the modem, phone app, settings, and deep deep in the system and hidden menu. So this can't be done yet but I still have faith because I want to test HSPA+ on this phone.

Straight talk does use CDMA and gsm, the phones with a model ending with a G are GSM. The phones with a model number ending with a c are CDMA

Only in certain areas they sell CDMA phones in most areas they sell GSM through T-Mobile only with bring your own device it allows unlocked CDMA devices but this phone is locked down hard on the CDMA and GSM side.

I get my wife a used S4 today that was previously on the Sprint network. We are on ATT and i planned on rooting the phone any ways. What all do i need to change to get rid of the sprint phone number that is on the phone, and what do i need to flash to make it work with the att network?
Don't believe it's possible. ..Sprint is CDMA and dont use SIM cards ATT uses GSM and SIM cards

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.

wow that sucks, because even Verizon who is the greediest of them all will let you use their phone on both AT&T and T-Mobile. I have the AT&T Galaxy S4 and I can use my phone on T Mobile as well.

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.

Is there any reason that the VZN rom had greyed out GSM settings. Does this mean that there are antennas that can be enabled with drivers or a SIM from ATT or TMobile?
Sent from my VS980 4G using XDA Premium 4 mobile app
The phone is a world phone which means you can put in any gsm SIM card and it will work with the Bands that the phone is equipped with. I have used it on T-Mobile and metropcs successfully so far.
Also the area is greyed out because Verizon doesn't have a gsm network for cellular use. Yet. Their LTE is deployed over gsm but it is data only.

Verizon would have GSM settings grayed out because it is not applicable to their network at all. The phone would come carrier locked so if you pop a sim card in from say TMobile then the phone still wont work. However if you were to unlock the phone (currently illegal last I heard, might change in a year or so though) it should theoretically work on ATT and TMobile and other GSM networks, although you may or may not have to manually input APN settings to get the network data working. The stock Verizon ROM though may also not include drivers for activating those radios bands wither, IDK if that is something they would do or not. All the versions of this phone use the Snapdragon 800 chipset, which has built in radios that can hit basically any network's frequency in the world.

Well at most only a small part of what I said is wrong so thanks for trying to correct me in in a very dickish way. Unfortunately you are also wrong, not all Verizon phones come unlocked from them.
digitaltrends.com said:
AT&T will let you unlock your device permanently, provided your contract has already expired. AT&T customers still on contract may unlock their devices up to five times per year (for international travel purposes), as long as they don’t owe any past-due amount on their accounts, and have been a customer for 60 days or more.
Verizon sells all iPhone 5s unlocked, meaning you could take your device over to AT&T or T-Mobile without having to unlock the device. But other devices, like the Samsung Galaxy S3, are locked by Verizon. However, like AT&T, customers in good standing can request to have their devices unlocked for international travel.
Sprint does not offer unlocked devices, but it will allow customers to unlock their devices for travel after three months with the carrier.

All verizon LTE devices are unlocked out the box... wasn't being a. .... despite your assumptions the gs3 is unlocked so is all their world phones. And I never said all their phones were unlocked I stated all lte devices which are world phones are unlocked out the box. I currently have every phone that has come out since the gs3 and all work on T-Mobile with no call to verizon. But I am not going to argue about it.

Nope, i'm actually surprised that Verizon didn't lock the phone if what the above poster said is true. The bootloader isn't what you need unlocked to move from carrier to carrier. Phones with sim cards are generally GSM and phones without sim cards are generally CDMA. GSM phones are normally locked to the specific carrier that you bought it from. CDMA phones are not usually taken on any other networks unless you are moving to a network like cricket which takes what it can get

As he said, Verizon 4G phones are all sim unlocked. Phones like this and the Note 2, which I just came from, have the CDMA and GSM bands. It is just as simple as putting in the SIM, change the APN, and be working. That said, the Note 2 could not get a 4G GSM signal only HSPA+ because of the bands it supported. I haven't checked the S5 yet, but I do believe I have seen that it does support some of the 4G GSM bands.
You are right about the CDMA part which is why it wouldn't be wise to buy, say a Sprint S5, and then come to Verizon because it does not support any CDMA bands.
so you guys can confirm that it is sim unlocked?
They always are. All Verizon Wireless 4G phones are SIM unlocked.

Bare with me if this seems like an absolutely stupid question.
When I travel I have a GSM HTC One S that I pop in a pre-paid SIM to use (say, 3 in Ireland). I believe this was a T-Mobile phone previously that I carrier unlocked. If I have a Verizon CDMA S5, I could pop in the 3 SIM and be able to use it (maybe not 4G depending on the bands) provided I updated the APN information?

Correct. I used my Note 2 in multiple European countries, lastly in Rome where it was stolen. Take your Verizon sim out at the airport, put the new one in, change APN, and voila.
(carriers I have tested with - Orange, Vodafone(multiple places), 3, Rogers in Canada)
Your S5 on Verizon isn't solely CDMA. If you look up any website with the bands it supports, you will see the GSM bands.

That wasn't the question. The question, as posed, was would it work? It absolutely will work with speeds up to HSPA+.
Will TMO be bound by the same restrictions re 700mhz as Verizon? My Verizon sold N7 works just fine with my TMO unlimited phone sim (have tried it many times); I'm not sure whether that's related to the above or that T-Mobile just doesn't see it as a tablet. My AT&T Note 8 does not work but that also doesn't have that band.

I don't really understand the question. T-Mobile 700mhz LTE may may not be deployed in your area yet. I know Nyc and its neighbors wont get it until beginning of next year.
