How To SIM Unlock Samsung Galaxy S4

Edited..
Since lots of ppl already reported that this method doesn't work...
I just read this post in redmondpie..
and I saw the comment and one of them is trying on S4 Sprint..
II really want to try this.. but my wife brought her S4 Sprint with her so I couldn't try this at the moment..
Maybe someone would like to try this out and report this discovery?
so here's the Link:

Be very carefully doing this on sprint S4 it may brick it cause this process only works for ATT- T-Mobile GSM phones only

I also tried it to many times with no luck I wish this worked.

Hello. Some one try to flash radio firmware from verizon sgs4(it has unlocked gsm) ? it work for nexus but vice verca

This method DOES NOT work. Sprint BLOCKS US GSM carriers. To get an international unlock you need to call sprint and ask for one. At this time there is NO way to get US GSM signal on the sprint S4.
EDIT: Apparently this will make your phone unable to connect to a femtocell. Be careful

Do not try this mod. It will mess up your phone and how it connects to the Sprint Airave.

Not that I am aware of. I am trying a complete factory reset of the phone. I will post my results when I can.

Please let me know how the factory reset works out for you. My phone is officially messed up. My 3g was not working at all. I would only connect LTE. After troubleshooting forever with sprint, my 3G is working again but it is very slow. I also notice that it does not auto roam to Verizon at all.

Updated: I have rebooted the phone next to the booster and then did a firmware update, PRL Update and rebooted the phone. It appears to be connecting again.

How was the speed though? It may show "3G" but my guess is that it's really 2G speed or something on TW.

I've had massive issues with my 3g after this method. The 3g is super slow and I know something is not right. Is there an app that displays the cdma band that the phone is currently operating on? I read somewhere that it screws up the phones ability to access the cdma 850 band.

What we really need to do, is find a way to undo this. Even though my phone appears to be working. I really wish I had never tried this and could go back.

Yes I hope someone figures it out. Reflashing the stock software is not enough

Update: My phone appears to be staying connected to the Airave and getting a very good signal. Data speeds were never really affected just terrible connections. :good:

I tried this also and it messed up my 3g speeds, after much searching, reading ,and experimenting,i did a SCRTN which restored modem ,lesson learned

There is another thread that is similar to this for unlocking the sim. I tried it, and possible messed my phone up. I was getting slow 3g speeds and mobile data drop outs. I fixed my issue by doing a complete factory reset/ clearing NVRAM. This is how I did it:
Dial ##786#
Choose Reset
Enter MSL
Here is the thread I mentioned just in case one of you wants to look at it. http://forum.xda-developers.com/showthread.php?t=2282683

##786# as far as I know will restore your phone to stock .
##72786# should reset your network settings. Just make sure you are in a working 3G coverage area or have a WiFi connection or it wont re-activate. This method does not put your phone back to stock...just reactivates it on the network.

Sorry for the unusable info...
But i got this news from Sprint Htc One thread, that they are able to unlocked the device by simply rooting the phone and sending a line in terminal...
Is it possible to do this with ours?

1. You should be rooted
2. Download https://play.google.com/store/apps/details?id=jackpal.androidterm
3. Run Terminal Emulator
4. Type "su" (excluding quotation marks) and grant it superuser permission
5. Type "am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity" (excluding quotation marks)
6. You will get menu on your HTC
7. In that menu, select "API", then scroll down 'till almost end and select "simlock"
8. Reboot the phone and hopefully it would accept GSM SIM
9. Enter *#*#4636#*#* in your dialer
10.In the phone information section(the first one) set preferred network type to something that is GSM specific: "WCDMA Preferred", for example. The phone will switch to GSM mode

Spotty 4g lte

Just got the One, coming from s2, and love this phone. However I'm on Sprint lte now, and get very spotty coverage. It constantly switches from3g to lte, sometimes no data at all.
Of course this is a sprint issue, but is there a Rom or other ticks that may help get more consistent lte connection?

Not really. I had to lave Sprint after being with them for 11 years due to my phone(s) not getting calls and poor network performance. In Dallas they really messed up big with Network Vision updates. Just my opinion.
Doesnt matter what hardware or software your on if the network is the problem your phone wont make it better.
Untill they get a handle on the system issues its not going to get better.

It's been going on for me since the beginning of July. It's not your phone, it's the awful network. The network has gotten so bad here, my local new station did a story on it since so many people were complaining. Normally I'm not a fan of stuff like this cause the media tends to exaggerate but in this particular case it's as bad as they say. I can have the tower in site and my phone will dump between X/1X/3G/LTE. Constant dropped calls, cutting in & out, unusable data, etc. I have been with Sprint for over 10 years & the network is literally unusable as it stands. It has been getting better over the last few weeks but it's still awful. I can understand some disruptions in service but this has been an ongoing thing for months with no end in site. Poor planning on Sprint's part. As far as LTE being spotty, until LTE gets turned on 800 it's going to be garbage. HTC one doesn't support LTE over 800 which at the moment doesn't matter since it's not on yet but I'm hoping by the Spring new hardware will be out & LTE on 800.

if your on a sense rom, ##data#, click edit, enter MSL (if you dont have it, sprint should give it to you), you will see LTE settings and LTE scan settings, (dont remember exactly what they're called) Lower both those numbers to like 30 and 5 or something like that, it will scan more often and while connected to LTE should stay connected longer on a weaker signal....there is a thread on it somewhere...

Thinking of going to Verizon after getting the M8

I have been with sprint for 8 years now. Just got the M8 for the new spark network that according to sprints coverage map, I was fully covered in. We'll, that's not the case. Been having a lot of problems, mainly if I drop to 3g, I actually have no data and no phone calls and can't send texts . I have to wait until I'm in an area that I think may have spark, and reboot my phone. Then I get a flood of text messages and voice mails. This has been going on 3 days now. Apparently this is a mass problem that could be a while to fix. I still have ten days to return it and reverse my contract. Sprint is so bad that if I'm somewhere I don't know where I'm at and try to pull up a route on maps, it will fail to pull anything up, or search for a route until it says no connection, even with 4 bars. It's hard for me to leave since I've been with them for 8 years, but I'm really getting tired of it. Would like to know of anyone else is considering this, or may have left Verizon for sprint and why.

I've been with Sprint a while too. Just LTE in my area, works great though. I'll see whenever spark comes to my area. Have you talked to sprint about this problem? Possibly a defective phone or your tower's messed up. Do you have the same issues on CDMA only mode?

Not sure it's possible but I wonder if loading the right PRL might disable Spark. Or there is a way to shut it off in the phone settings.
LTE is still up and down for me so I leave my phone on CDMA 99% of the tie for stability.
Most places that I need speed I have WIFI.
LTE just isn't there yet.
I'm on hairy edge at home and hairy edge at work (both places I don't need it).
Even when I'm in strong LTE areas if you hit a 3G pocket the phone behaves badly.
Have not had it long enough to know if it's better or worse than HTC One M7.
But I switched it to CDMA.
I just loaded PRL 56018. So it roams on VWZ (3G only).

I have had sprint over 10 years now. Only reason I stay is I'm on Sero Premium. The network is absolutely horrible in my area. Dropped calls, week signal, 1X/3G/4G no data. I'm sticking it out for Spark & hoping 800 LTE will fix the coverage issues. The m8 has had better signal and seems to lock on a lot quicker. So far haven't had that many issues with it besides the network still sucking of course. If you don't have a good plan on Sprint I would leave. I think it will get better over time but it's still going to be a while yet. I have had problems since last July.

I left Verizon because of the ridiculous bills I kept getting. Boy is their network amazing. Signal and LTE everywhere.
Got the Sprint HTC one m8. I mean Sprint is just terrible. LTE barely works barely have a signal anywhere. Love the phone but only on WiFi around the City

Same here. I got I think 9 people on my Sprint family plan, we've had Sprint for over 10 years now. I left for Verizon when the galaxy Nexus was relleased. Man, I loved Verizon, but my bill was upwards of $120 per month. Luckily I got to deal where if yo bought 2 or 5 GB plan, they would double it. So i had 10 GB of data at that time. The service was unbelievable, but I hated the price. So after 9 months, I came back to Sprint. Here in Boston, the service is great, but I've also seen a sporadic in and out connectivity.

Well I made the leap. Went from 03mb to 21mb at work.

2nd bad M8...sigh...

Looks like I have wound up with LTE connectivity issues on my 2nd M8. It's defaulting back to 3G and never trying LTE again. I'm in an area where the circuit fallback has already been installed and is up and running, so it shouldn't be that. It randomly just stopped working properly over the weekend. Sprint has told me there are no issues in my area, no work being done.
Is there any chance HTC or Sprint acknowledge this issue with their phones? What is happening under the hood to cause the phone to randomly get mucked up and never be able to get back to normal? Or is there a way to get back to normal?
Profile, PRL updates, rebooting, airplane mode are all (very) temporary fixes for a bigger problem. It acts and feels like a software issue, but is it something that can be reversed or does it get embedded into the firmware, never to be removed? I've tried flashing firmware multiple times without rebooting, over top of itself more than once, hoping to knock out or overwrite something wrong inside. I ran OMJ's h/k RUU last night and it connected to LTE as soon as it rebooted, but today it's right back to where it was.

Its really difficult to tell if its the device or the network but for the most part calling sprint is no doubt a waste of time. Over on the gs5 forums you hear the same complaints all day long. As a matter of fact, go to any sprint tri-band device forum and you will know doubt hear the same exact complaints.

Goto to a Sprint Store and Compare it Side-By-Side.
It's the only way to know for sure.

That may or may not make a difference, two of the same devices in the same location can be connected to different towers unless he uses an app to confirm that both are connected to the same tower and even then I have had experience with two exact devices connecting to the same tower and issues with that tower actually affected one device and not the other and nothing was defective with either device. Weird

So far, I am, one of the lucky ones with an, s5 that hasnt had a bit of problems.

Don't get me wrong there are some s5 owners that have had problems but u m8 guys seemed to be getting hosed pretty bad.

I'd say keep a very close eye on them both. My 2nd one was perfect right out of the gate and stayed perfect for 3 weeks, then suddenly just poof it's jacked. It's not as bad as my 1st, but still frustrating. The 1st one wouldn't stay connected to anything, certainly not LTE. Now mine just wants to revert to 3G as soon as it possibly can. Very strange.

My daughter gets very good data with her g2, picks up lte in areas I don't and it gets me frustrated, it sucks I don't no anybody who has a m8 to compare mine with, I'm gonna have to wait till my wife gets hers with her upgrade

I think it's certainly possible but not that common. And if they do behave the same then he's probably ok. If they don't then he'd have to dig deeper.
One store had several M8's on display and the all behaved identical and very different from mine.
I should have 3 of them tonight to compare One being returned to sprint and one that will get sold in the end.

As a sprint rep who lives in an area that sprint spark and bands 2600 and 800 are being implemented I assure you it is not your device, it is the network. This is happening on all lg g2s, g flexs, s4 tri bands, s4 minis, nexus 5s and gs5s. Since the Soft Bank by out Sprint is doing a massive overhaul on their network. Sure service might suck ass for a few months but you'll appreciate it when its done. Hang in there, its more than likely not your device.

Sent from my 831C using XDA Premium 4 mobile app

I see it daily man. From what I have been told, they had problems with cross connecting calls when implementing spark. Since then, they resolved that issue but then created the 4g data/voice connectivity issue. Meaning when you are on 4g, the tower isn't telling your phone when its receiving a call. Ever wonder why the m8 cannot talk and use data at the same time? However an s3 can. Does that phone have this issue? Nope. Its not so much our phones but more so the towers not communicating to our phone the way they should. This is why when you switch to CDMA only instead of CDMA/LTE, you receive voice calls and texts. Again, you can change this in settings/mobile data/network mode.

LTE only mode works perfect when I enable it. It connects to band 26. Switch back to LTE/CDMA and LTE refuses to connect. The reason I'm confused is because everything worked for 3 weeks straight in perfect fashion. The Sprint rep I spoke to said no work was even being done in my area. @johnnygabe89 can you help me understand how this could be?

Sprint Triband LTE devices do not support SVLTE (Simultaneous Voice and LTE).
In previous Sprint LTE phones, when a device was in Sprint LTE coverage it would park in both the LTE and CDMA Sprint networks at the same time. When a voice call came in, it would just go straight through to the device. And signal to the LTE network would be maintained the whole time while the call was active.
In contrast, a Sprint Triband LTE device can only stay on one technology at a time. CDMA or LTE, not both. So when a Sprint LTE Triband device is in Sprint LTE coverage it parks only in LTE. And doing so means it cannot transmit calls without Circuit Switched Fallback (CSFB) on the network side. CSFB and eCSFB (Enhanced Circuit Switched Fallback) are network controls that will allow a single mode/single path network to operate in two modes, both CDMA and LTE.
Here is how it works in the simplest way I can describe. When your Triband LTE device has an LTE signal, it cannot receive or make calls on its own. It is just using LTE data happily. However, what if someone calls you? How does it get through the CDMA network to your device? Via CSFB.
When the Sprint network tries to forward a call to your device but cannot see it via CDMA, it then checks for an LTE connection to your device. If it sees one, it tells your device to disconnect from LTE for a moment and reconnect to CDMA. Your device then jumps over to take the call on Sprint CDMA and the LTE session is interrupted. This happens very fast and seamlessly. Except for the loss of data availability. If you receive a text, the Sprint network is able to route it to your device via LTE.
Circuit Switched Fallback is a great solution to the issue of Sprint Triband LTE smartphones. But the problem here is that the Sprint network is being upgraded in Network Vision, and not all Sprint parts of the Sprint network can currently support CSFB. And it affects all Sprint Triband LTE phones
If yoou want you can read this article all the way thru

I don't think it's a circuit switch fallback issue. This morning I'm connected to band 25 and lte is working. It's when I connect to band 26 that it disconnects. So maybe its not a broken phone?

Well from what I have gathered from all my reading about the issues is that Band 25 is the Sprint Triband LTE, and Band 26 is the older SVLTE (Simultaneous Voice and LTE) and may not support the CSFB and eCSFB yet.
I could be wrong in my assumption

I feel like I remember reading that band 26 is the new frequency 800
Sent from my 831C using Tapatalk

I also think it's the network. When I first got the phone, I experienced the 3g of death, but have not experienced it much lately as it seems like Sprint is updating their network in my area.
I'm getting LTE in places now that I have never gotten on my M7.
This weekend, I went to LegoLand, which is a highly congested area, and was getting the 3g off death again, which I believe is related to the network. This is similar to when I went to Disneyland with my M7 last year and could never use Sprint service in the park to due to it being a congested area.
I find it helps to turn off roaming in areas where you get the 3g of death and just connect to the Home network. Try that and see if you get better results. It seemed to work for me this past weekend.

It appears that my area is getting LTE added to the Band 26 800Mhz frequency, though it's not fully up and running yet. So my M8 is scanning and sees that band available, and most likely prefers that band, so it connects but it's not fully implemented yet, so it kicks back to 3G. There was a moment this morning where I had fully working LTE, and lo and behold I was on Band 25, not 26.
If only there was a way to disable Band 26 on the M8 until it's totally up and running...

im facing these issues too..it sucks

LTE: EMM-65535 and loss of provisioning

Well, I just bought the HTC One M8 Harman Kardon edition to replace my Evo 4g LTE, and overall it's not a bad phone. Like the audio and speed of the phone.
However... It doesn't work very well as a phone. If I go into an area where signal is sketchy, I will get the above error (Loss of Data, LTE: EMM-65535). Okay, I understand I am in a low signal area.
BUT... When I get back into signal, the phone has lost it's provisioning. I have to do the whole ##72786# routine to get the phone to take/make calls, accept texts, etc etc.
First Sprint says it's a provisioning issue. Then they tell me its a hardware issue. The local service center tells me they have seen numerous phones come in with this, and they replace them, and it still does the same thing. The tech said it is an issue with the network not handling the new Spark network, and to put the phone into CDMA mode for a week to see if it clears up or not.
My phone is stock right now (Still, S-ON and locked).
Software 1.54.654.13
PRL 51100
HBOOT 3.16
Radio 1.05.20.0321_2
I've tried restricting the phone to Home Only, putting it into CDMA mode, and it still does it. I'm about ready to reactive my Evo just so I have a damn phone to use.

I just returned mine for these very issues. Many complaints in the Sprint Community forums.
For me, 9 out of 10 phone calls in or out fail, if you get lucky and make a call you might get 20 seconds in before it's disconnected. Virtually zero data. This was at my house, and different places around my area of town. I really liked the phone itself though.

Sprint believes the phone is defective. I don't think it is. As long as I am on my home cell, it's fine. I leave the area, and pwoof!
The phone shipped in LTE/CDMA mode.. Sprint advised me to try it in Auto and see what happens. They also pushed a network ticket to see if there is anything wrong there.

I had the same issue, brought it in the store and they swapped it, said it was the SIM card reader. I've had my replacement for over two weeks now and no issues.

After putting the phone into "Auto" mode, it seems to be working fine so far. I'm trying to get it to choke so I can further troubleshoot this issue. If not, I am going to drop by the Sprint store where I bought the phone and see if they have had any reports of this.

I had the EXACT same issue with my M8. Sprint replaced it with a brand new one and it's been absolutely perfect.

Going to drop by a Sprint store on the way home and see what they say...

I also had these issues with my first M8 the second day I had it returned it and it has worked perfectly now for about 2 months now I would say it is a defective phone

Well I went to the Sprint store, and they replaced the phone without question. Something that I thought funny... My "old" phone came out of the box with 1.54.654.13 on it. The "new" one came with 1.54.654.9 on it. I asked the tech in the store, and she said the "new" phone just came in on a shipment today. That doesn't really mean anything, though...
Out of the box, it had the LTE error again, but this time it added a EHPRD: 33 below it.
The tech in the store said that all of Sprint's Spark phones are having this issue, not just the HTC.
I will wait and see what happens. The phone has the same signal characteristics as the "old" phone.

Having the same issues as everyone above. Visited a Sprint repair store several times. I had the device about a month without any issues, then suddenly calls dropped, data wouldn't work, texts wouldn't send, yada yada. Factory reset, RUU, all the dial codes, nothing helped. The Sprint reps first seemed like this was an oddity, then admitted they've had numerous complaints nationally with the device and the network. They claim it's a network issue, only to be resolved by the Spark upgrades.
It's been about 3 weeks since I've been able to use the device as a phone. Not sure what to do as I don't trust Sprint and their ETAs (they claim network improvements "finished sometime in June" in my area will resolve it).

1.54.654.13 the problem?

Had the same problems with my phone. I activated and updated to the latest OTA update (presumably 654.13). It was working, then it started dropping calls, no data, and the LTE error message. I took it to the store and they told me it's an HTC software issue, I'd have to just wait for an update. Not satisified after a week of not being able to use my new $600 phone, I decided to call and get an exchange. After some wrangling, they finally sent me a new one.
The new phone is on update 1.54.654.9, but it wants to update to 1.54.654.13. I shut off the auto download and decided NOT to apply it. So far so good. I can make and receive calls again, data and texting work great too.
My thinking is, 1.54.654.13 has the bug. With only the 1 phone, I'm not going to try it for now.

I believe the .9 RUU is available.
