[Q] SCH-I545 Sim Unlock - Verizon Samsung Galaxy S 4

I've searched quite a bit and I saw a few threads that said that the Verizon GS4 comes sim unlocked. But I put in a friends Sprint Sim and I got an error message that said "non verizon sim." I also saw tutorials on how to go into the phones menu by typing *#06# or *#0011# but these do not work on my phone. Is there a code that will work on my phone? Also, do I have to install a custom ROM on this phone to get the sim unlocked? I really don't want to go that route but if I have to I will.

Sprint SIM probably isn't compatible. Try a GSM carrier SIM.

I tried the T-mobile version Straight Talk card and it says the same. "non-verizon SIM"

OK. I found out that you have to enable the hidden menus first. There is a forum here that talks about it. It's titled [how to] Enable Hidden Menus for Verizon Galaxy S4. And from there you can sim unlock.

I've seen reports that people where getting non- verizon sim message but phone still worked on other carriers.

This is true. I have put in an active ATT sim got "non-Verizon SIM" message and could still make calls and Internet from the ATT SIM.

This is only works with gsm. The cdma side is still locked unless you call Verizon and get them to unlock it.

I am currently in China and trying to get my sch-i545 to work with a sim card I purchased. While my phone is able to recognize that the sim card is there I recieve the message that the sim card is from an unknown source. Is there any way to fix this with the sch-i545 even though it is not the international version of the phone.

Are you rooted? Are you running a custom ROM?

Are they capable of doing this with the S4? Assuming they are, are you speaking theoretically or with certainty? Could you confirm via experience or perhaps cite the information?
Reason I'm asking I tried to use a non-Verizon sim once with limited success on an S3. Called Verizon to see if it was a sim-lock related issue and they insisted that the phone shipped as unlocked as could possibly be, which would contradict your statement assuming the same holds true for the S4.

That's interesting, but doesn't answer my question - that being about Verizon being able to unlock the S4 for CDMA carriers. I'm aware that it's GSM unlocked.

Sorry I misunderstood. Don't mention sim unlock to them since the cdma doesn't use the sim. There is another thread floating around here that mentioned this but I couldn't find it. What it boiled dien to was telling that you are traveling overseas and would like them to unlock cdma. This doesn't Guarantee that they will. Sorry I couldn't find the link.

Anyone ever call Verizon and had their s4 or S3 unlocked thru them before who finished their contract? If so can you explain what the process was they walked you thru?

I popped in a tmobile sim in my vzw s4 and it worked without any mids. It just says unknown sim but it works

Actually it's quite easy to do. You go on your My Verizon account, or call them and add the $4.99 international package. That does NOT include any data, only the capability to use it on CDMA elsewhere or the Global option on your Verizon Sim.
I recently traveled to Sweden and have used several different Verizon phones (with International SIM) outside the USA and not had issues.
The "Non-Verizon" sim message has absolutely no bearing on being able to use another sim in the phone, its UNLOCKED. If it's a GSM simcard voice will work no problem, data you have to add APN in. You cannot use a Sprint SIM because like Verizon they use authentication by way of ESN or IMEI to be registered on their CDMA network. So it just won't authenticate.
So you don't need to SIM unlock, it's already unlocked.

I tried L720 unlock mode, failed

Adding this feature does not cost anything on my unlimited plan. Only if you want to add additional global data and voice rate plans does it cost to enable the feature.

OK so in that case how do we get 3g and higher speeds when using other Sims? I took mine too ATT they put in the sim and still wouldn't get more then Edge data, We also have a Ver S3 that we have on ST prepay and put in the APNS and we still can't get above edge data either. Here the thing, the s4 is global ready yet it still has some kind of lock to prevent data so has anyone ever contacted Verizon after theit contract to come about unlocking their device to use on other carriers? What is the point of buying these phones, if they won't unlock then for us after contact is up? It would still be there phone, seems were just leasing it cause we can't take it with us to another carrier. Any guide to get these unlocked for3g and data please?!!

GSM Works on DINC4G, Here is how to do it...

I was curious because I heard that the Droid Incredible 4G has a GSM radio in it so I did an experiment. I used a T-mobile micro SIM. I used the 4GLTE switch app for the Thunderbolt to access the hidden menu and I changed the radio mode to one that included GSM/W-CDMA. I popped in my T-mobile SIM and, presto, I got a T-mobile signal. I tested and I was able to make and receive calls and text messages. I had to manually set the APN for data to epc.tmobile.com and now I have EDGE data. I am sure an AT&T Sim will get HSPA+. The GSM appears unlocked now but hard to access. I am afraid, however, that once Verizon releases the update to make GSM roaming available, that it will be locked. Anyway, for now, you can pop in a GSM SIM and use your phone native.

Works on AT&T with EDGE data as well. I haven't gotten HSPA (any variant) or AT&T LTE working, and I can't play with it too much because it's not my SIM
ATT LTE won't work because the frequencies are different from Verizon but I am surprised that HSPA didn't work. Did you use a setting that included W-CDMA? GSM only would likely mean Edge only.

Im afraid I cant get this to work. Does it require a rooted phone?
I have the app, I have a T Mobile micro sim installed. I click on the drop down menu (within the app) and choose the first menu item "Select radio band" and pick PCS (1900-MHz Band) and I get a "successful" prompt afterwards (only when the Tmo sim is installed btw).
I am unable to choose "GSM Only & GSM auto (PRL)" menu choices. Is this normal? I am able to choose GSM/WCDMA/LTE auto though. I dont get any sim error messages, but the phone never seems to want to camp on any GSM network.
You are looking in the wrong place. You need the drop down menu that includes GSM, W-CDMA, EVDO, LTE in various combinations. Select one with GSM in it. Also, I found that you need to have your Verizon SIM in first and then hot swap it with the t-mobile sim.
On the Rezound if you make a couple build.prop tweaks it fixes texting and data on GSM.

No, I was in the right place to begin with, I just thought it would be able to pick just gsm but it wont.
And you left out that piece of informationin bold, but still not working...
Can you give us your firmware & radio version, perhaps some phones have been updated to block this.
Anyone have any luck with this?
OP, is your phone stock? Rooted?
What if it has a bad ESN will this work or a way to make gsm work even with a bad ESN I'm asking because if Verizon does not have droid 3 s I will get this phone then go with at&t but will like to know if I can change the radio so I can so this

One additional thing I found was that I got it to work by hot swapping the Sims. It seems like the Verizon sim has to be in when the phone boots. Once it boots, use Phone Info to change the mode to GSM and then switch your sim.

I would think it should work. The ESN is used for the CDMA networks, the IMEI is used for GSM. Stick with GSM and you should be ok...
Dinc 4G now Global Ready
I was just chatting with a VZ rep online and was told that Verizon has already released a software update, thus making Dinc 4G officially global ready. Can anyone confirm/deny?
I asked her for a software version number which enables this, but she wasn't able to provide it.

SIM Unlock for US networks

I don't really know a lot about SIM related stuff, so I apologize...
Can the Rezound be SIM unlocked for US networks? The only thread I've found on another site says no but I think the repliers were referring to bootloader unlocking, not SIM. I am S-Off if that matters..just don't want to spend money on those sites that use IMEI to unlock, then get nowhere.

Just to be sure about the specifics.
HTC rezound on the leaked 4.03.605.2 ruu
You put in a T-Mobile sim card in the rezound
And you had voice calling, texting, mms, and data working?
You didn't need to modify anything in the phone, change settings, add a T-Mobile apn, root, or Rom the phone?
It will be nice if you will write a short "how to" for moving a rezound onto USA T-Mobile.
Also were there any frequency mode restrictions?
Data speed was good?
Thanks,
Howard
Thanks guys...will keep messing with it.
Verizon would not give me an unlock code because according to them the phone isn't capable yet.
Rezound is globally capable and works on other US carriers

The FCC ruling that Verizon is responding to by making the Rezound, Razr, Droid 4, etc. globally capable also opens the phones up for use by other carriers. This was "Big Red's" initial impetus for not unlocking the phones native features. So yes, you can use this phone on Tmobile's network.

Have you tried to enter T-Mobile's APN?
It won't save and show in the list.
It appears Verizon locked it to only use Verizon's APN?
when booted into the bootloader there is a simlock item on the menu.
if one has s-off and an appropriate config.dat file on the removable microSD card it is supposed to SIMM unlock, so one doesn't get that sim locked picture on the phone after inserting another vendor's SIMM card.
this information is from reading, not from doing it.
I'm running T-Mobile US (EDGE) just fine. 100%
Did nothing but put the simcard in the phone and flashed a GSM ROM (Downtown).
I did flash the latest radio and firmware with S-OFF but everything was working before hand.
I activated the Prepaid Simcard on T-Mobiles website and used the Rezounds IMEI without problems just added the right APN for MMS and DATA.

Thanks Tachi,
I plan to order a T-Mobile SIM card to play with on monday. it will have 10 minutes of talk time, but no data. I still have quite some time left on my Verizon contract before I switch to T-Mobile. This might also be a good option for my daughter.
First, I will see how this works on my stock rooted 4.03.605.2 system with htcdev unlock and s-off. If I get the SIM locked warning, I will try installing a hboot loadable SIM unlock config.dat file I got from a website - it has my IMEI inside it.
I don't know why, but I can not enter the T-Mobile apn in my system, even if I switch the phone into gsm mode.
Then I will try the downtown ROM, if it is ok to load it ontop of 4.03.605.2
thanks,
Howard

Global GSM not working

Hey i came to hong kong for a business trip and tried a local GSM sim but i get this sim is not supported error. DOes anyone know how to fix this.
I tried same thing sim on another phone it works. So not sure what the issue is ? did i need to get an unlock code from verizon before i left ?
If you can get access to a computer for awhile go through Adams unlock process in the original android dev forum and you'll be carrier unlocked, not sure what Verizon would give you for a code cant hurt to call and ask, but keep in mind unlocking it is something that can be done by you from here

You sure it wasn't a "Non-Verizon SIM" on going notification? I've read of people using all sorts of different carrier SIMs and they all had at least voice/sms service if they had a signal. The phone is already SIM unlocked, so VZW couldnt give you much.
Sent from my Galaxy Note II
The non-Verizon SIM notification doesn't actually do anything. You should be able to get voice just by putting the SIM in. To set up data, you'll need to be rooted and add the APN manually.

DNA working simultaneously on Verizon and AT&T?

Has any Verizon user tried placing AT&T sim card into the phone, while the phone is already on Verizon service? What will happen? Can the phone receive SMS and calls from both services?
Please share!
You need the Verizon sim card to get Verizon service.

I've heard of some people using the gsm slot for att, but i believe you're thinking that since verizon doesnt need a sim and att can use it you can use both carriers on one phone. THIS IS NOT POSSIBLE. lol.
The DNA is a worldwide phone though and some people have had it working on att. But only one service at a time

[Q] Unlock Verizon Samsung Galaxy S4

Is it possible to unlock the Verizon version of the S4? I'm deploying in 4 weeks and would like to use my phone with international carriers. I have an SCH-I545 build and I'm still running on stock. Thanks
I think ATT has begun to unlock phones internationally when asked.
Verizon? Not sure... one think to check is if the Verizon GS4 supports a carrier in the country you travel to.
Take a look at Leo Laporte's Tech Guy show... he has callers ask this quetion on average every other week... I think he has show notes on his site now days... techguylabs.com

Verizon phones are unlocked out of the box, but you have to make sure that the country you are going to has a GSM network.
After a lot of searching, I decided to ask this here:
I have a Verizon S4, but I was wondering if it was actually unlocked out-of-box or if there is something I have to do in order to use it with, for instance, Cricket, or U.S. Cellular. I have done lots of rooting/developing for Android, but have never tried to use an Android phone with a differing carrier. Can anyone help or point me to a thread that helps? (Again, did lots of Googling and XDA-searching)

The phone is GSM-unlocked. This means that you buy a SIM, plug it in, then add the proper APN to enable data. (Settings, Connections, More networks, Mobile networks, Access Point Names). The "+" (Add APN) button is disabled if you have a VZ SIM installed but will be enabled if you insert a non-VZ SIM.
Whoever you get the SIM from will tell you what to enter for the APN.
Whether or not it'll work and how fast a network you'll get depends on the bands that the local carrier uses.

HI k1mu,
So do you mean to say if I purchase this device with full price from VZW ~$400 (month to month plan),
the next thing I can do is take off VZW SIM and would it work on my AT&T GSM SIM in US?

Maybe. While the VZW version is GSM-unlocked for international use, it is unclear how well it works with US GSM carriers. Some people say they can get it to work, some say they can't. Theoretically, it should only take you putting in an AT&T SIM then plugging in the APN data for it to work, but some people still say it won't.
So, you should be able to, but going by the accounts of XDA members, it doesn't always work, which may or may not come down to user error.

Thanks joshm.1219,
It still leaves me in a dilemma.. I do really want to get a "S4 mini" model but don't want to stuck up with CDMA providers to be true. Might want to use with ATT or Tmobile or H2O.. I visited the VZW store and the model has option under networks as
1. Global
2. LTE/CDMA
3. GSM/UTMS
Now the Qs are,
1. If this model does have a SIM card slot, how at the first point VZW has lock on it
2. When i asked the VZW associate, he was not sure whether they ever do unlock the device or not
3. If I am ready to pay off complete price of the device which is ~400, what else I would need from them to really 'UNLOCK' it?
4. Is there any means by root/flashing to make such model work for US GSM carriers like H2O or even T-mobile.
Sorry to be so annoying but m new to all these things and quite confused :crying:
many Thx in advance..

Thanks joshm.1219,
It still leaves me in a dilemma.. I do really want to get a "S4 mini" model but don't want to stuck up with CDMA providers to be true. Might want to use with ATT or Tmobile or H2O.. I visited the VZW store and the model has option under networks as
1. Global
2. LTE/CDMA
3. GSM/UTMS
Now the Qs are,
1. If this model does have a SIM card slot, how at the first point VZW has lock on it
2. When i asked the VZW associate, he was not sure whether they ever do unlock the device or not

Sorry I can't be of more help, I've been on Verizon for 10 years now, but it is by all intents & purposes, fully SIM-unlocked. It's simply unclear as to why some people report problems of using Verizon phones on US GSM carriers. If you really don't want to worry about it & are willing to pay full price, purchase a device through the carrier you want to use it on.
here is the code to choose network
you might need to change the network frequency to gsm if you wanna use it on att or tmobile and when you wanna switch back to verizon choose wcdma try dialing *#*#4636#*#*:good:

I've had people argue with me over this, but the fact is that NO Verizon LTE phone is SIM-locked. None. Nada.
People who claim differently are simply misinformed. (My I545 comes up on AT&T when I plug in my UK SIM and switch to GSM.)
Not to say that all VZ phones are unlocked - my Inc2 had to be unlocked before it would work with that same SIM. If I remember right, it wouldn't connect in the US, either, even after being unlocked. Not so for the GS4.
I appreciate the posts here from people who know. As for me, I am switching to tmobile and will attempt to use this there. If it doesnt work out, I will sell it on swappa and get a nexus 5!
Hi,
Verizon S4 with 4.3 is international unlocked by default.
You just need to select network mode 'GLOBAL'. Then add the right APN.
I am using Indian GSM SIM with the GLOBAL mode selected. All is well for me.
I can provide screenshots if anybody wanna see.
Verizon phones are unlocked out of the box and they DO work fine on US carriers I'm running my Verizon S4 right now on AT&T and I also ran it on tmobile for short time,
even works with Walmart straight talk and Net10 as those are just subsidies of T Mobile and AT&T anyway.
so don't sweat it if you have a verizon phone that uses a sim card, you can run it on any network that uses a SIM card US or international.
baseband issue
Doesn't the MK2 baseband with jb 4.3 block US Sim cards?
Or do I just have a weird s4?

The S4 is supposed to work globally right out of the box, as long as you've called Verizon to enable International roaming on your account. But, used that way, you'll be paying Verizon for International roaming and it's bloody expensive.
The question is, can you remove the SIM and put in a SIM for a local carrier in the foreign country where you are and use the phone on that carrier? That is what being unlocked would allow you to do. Past Verizon phones have not been unlocked to allow this. But, if you called Tech Support and told them you were going to, for example, Europe and wanted to use a local SIM, they would walk you through unlocking (at no charge).
I read a report that the S4 is not locked and that you can use a SIM for a local carrier in Europe, as it comes out of the box. But, I would not trust that. I would call VZW Tech Support and tell them exactly what you want to do - i.e. don't say "can I use my phone in Europe?" The answer to that is yes, you can, at about $1/minute. What you should ask them is, "can I travel to Europe and purchase a SIM from a local carrier and use that in my phone?" If not, they should be able to walk you through unlocking the phone, so you can do that.

to answer your question simply yes.
let's say I take my phone to Spain are somewhere in the UK, I'll go to store buy a SIM card for local network and BAM local phone number in Europe making phone calls, you can even get Data to work if you have that local carrier's APN settings
no unlocking is required because it is not locked.
other companies AT&T, Sprint, t-mobile, yes you have to get The phone sim unlocked.

This is 100% correct. NO LTE phones on verizon are sim locked. They are REQUIRED to keep them unlocked because of their agreement with the FCC for their use of the spectrum they lease. NO OTHER CARRIER must abide by these rules. Only VZW. Sprint I've heard will unlock ANY phone that is capable if you ask them too, and AT&T will NOT unlock any of their phones unless it 2 years old and out of contract (which makes no sense if you have to pay them while under contract anyway). There was a big deal about the Iphone 5 when it came out with LTE for verizon. If you bought a Verizon Iphone, you could put an ATT sim in it and it works, but not an ATT on VZW because ATT keeps them locked.
The Dinc 2 above was NOT an LTE device. Therefore no sim card....and it wouldn't work on most overseas networks anyway as it was a CDMA only phone. I believe VZW tested the limits of the "unlocked" SIM with their first few LTE phones. My Rezound worked with a GSM network sim....but voice and SMS only. It took some unlocking of the bootloader and rooting to run a special Rom to get Data to work on it.
I am heading to the Caribbean in a few weeks, and I will be using a rented SIM card to be able to message back and forth with my wife (with a data based messenger service as data rates are far cheaper than SMS rate there)

I just spent a week in the UK with an ekit.com SIM in my Verizon GS4 - no problem with getting service, no Verizon charge (even though I was on the Vodaphone network for at least some times.)
And the dinc 2, while not LTE, was CDMA/GSM - not just CDMA (yes, the dinc was CDMA-only), so it did accept a SIM card. I'm using that in the GS4 now that it's cut down to micro SIM.
That phone WAS SIM-locked, but VZ happily unlocked it. For the GS4, I didn't have to do anything with VZ to use it off their network.

Is it possible to unlock the Verizon version of the S4? I'm deploying in 4 weeks and would like to use my phone with international carriers. I have an SCH-I545 build and I'm still running on stock. Thanks

DOES ANYONE KNOW HOW TO
UNLFOK s4 UK VERSION sorry I'm new to the website
furballbeethoven said:
After a lot of searching, I decided to ask this here:
I have a Verizon S4, but I was wondering if it was actually unlocked out-of-box or if there is something I have to do in order to use it with, for instance, Cricket, or U.S. Cellular. I have done lots of rooting/developing for Android, but have never tried to use an Android phone with a differing carrier. Can anyone help or point me to a thread that helps? (Again, did lots of Googling and XDA-searching)

The phone is already unlocked for SIM and other carriers, all you need is the correct APN for the carrier. I currently have T-Mobile on my i545 and everything works on it.
