Hi,
I just received a S4 for AT&T. I have service with T-mobile. With my previous phone (At&T galaxy note 2) the T-mobile service was absolutely horrible until I found a tutorial to run T-Mobile 3G/4G AWS bands on the AT&T Galaxy Note 2 SGH-i317. So in order to receive full tmobile 4g on my AT&T S4 will I have to go thru the same process?? or will just unlocking the and putting my the phone be sufficient. Please let me know:good:
thanks in advance
I unlocked mine this morning by putting my coworkers T-Mobile SIM card from his S3 in my AT&T S4. After a swift boot up it showed T-Mobile 4G in the status bar so just putting the card in will be enough to get T-Mobile's 4G variant.

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

Because its for international SIM cards. Your Sprint S4 WILL NOT WORK on any US carrier other than Sprint.

I can confirm this. I work as a Sprint wireless consultant. A sim unlocked phone from Sprint is not compatible with any domestic carriers.

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.

Or buy an unlock code from Amazon or ebay if they wont give it to you ofcourse

thinking of doing the same with my s4 on sprint and going to aio. Been with sprint over a decade and finally over it. In houston and lte sucks.
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 tried and tried to unlock my Sprint S4 for domestic SIM but I have failed time and time again. I got it unlocked for International but Sprint has somehow managed to block the S4 from working on a Domestic carrier. I'll let you know if I have any luck.

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.

Sell it and buy a Verizon s4. Sprint's s4 is not compatible with Verizon's LTE signal. You would only be able to use 3g.

OK thanks n I'm OK with only 3rd working
I guess I should have told you it really isn't possible. Verizon won't activate a Sprint phone on their network. So you would have to clone an existing Verizon phone's esn in order for it to work. So basically you are better off with it on Sprint our sell it.

On January 24th, 2014, I switched from Verizon to T-Mobile mainly for the price. T-Mobile is sending me a reimbursement for the early termination fee that Verizon charged.
T-Mobile service in my area isn't as good as Verizon and AT&T and I want to switch to AT&T and use my LG G2 that I got from T-Mobile.
I am planning to switch very soon after I receive the ETF reimbursement in the mail.
Will there be any problems with using my T-Mobile LG G2 when I change to AT&T? I have seen some specifications and saw some differences between the T-Mobile and AT&T G2's. Will I still be able to get good AT&T service with the T-Mobile version of the G2? I entered the IMEI# on AT&T site and it shows it's compatible, but was just wondering if it is going to have limitations.
I'm wondering if I should just sell my T-Moble LG G2 when I switch to AT&T and just buy a new phone(possibly an AT&T LG G2)
I use my T-Mobile LG g2 without any problems on AT&T. I did the exact same thing you are doing

Thank you for the reply, are you able to get 4G LTE data and get the same voice signal as you would on the AT&T version of the phone? I just don't want to get worse service than I would get if I got the AT&T version of the phone.

Wait did you just say "AT&T and I want to switch to AT&T..."? Lol. How did that convo go? You: "T-Mobile is jank! Why didn't I check coverage before I did this!?" AT&T: "Idk! Come to our network! Its what the cool kids do!" You "I don't know..." AT&T: "Oh come on! Do it! I want you too!" You: "Okay!!" And... scene.

The tmobile G2 is lacking LTE band 5 which AT&T uses. However my understanding is that AT&T had not deployed band 5 in many areas so there should be no issues.
I am considering doing the same.

I used my G2 on att and got LTE. You'll have to input the APN, but a quick Google search will help you find that. You'll have to pay the phone off or it will get blacklisted and you'll have to get T-Mobile to unlock it which shouldn't be hard once you pay it off.

sorry it looks like this message was months ago, but I want to ask what APN you used to get AT&T LTE to work on the D801. I tried various APNs I found from google searches and I was not able to connect. Using the 'phone' APN, 3G HSPA connects and the data works (a bit slow in my opinion, much slower than t-mobile). I changed the APN from 'phone' to 'pta' and it doesn't connect to anything anymore.
Furthermore, I went to the network settings to choose the network manually. The phone sees both T-mobile and AT&T for GSM, WCDMA, and LTE. When I choose AT&T LTE, it says that it cannot register. The WCDMA and automatically connect choices registers properly. I tried this for both APNs 'phone' and 'pta'. I also saw on some websites 'wap.cingular' and another APN I can't recall right now, so I tried those an no luck finding LTE on AT&T.
yes, this phone works on LTE and WCDMA on T-mobile. The phone was advertised as unlocked and it does work with AT&T 3G. The phone should support AT&T LTE on 700mhz, 1700mhz, and 1900mhz. I live in the Boston area, so I should be able to get one of these LTE signals...
