Did you received any sort of OTA when Sprint unlocked your phone?
Currently Sprint claims that they just mark the phone as unlocked in their DB and then you need to restart it.
It clearly doesn't work for many, the phone still shows "Invalid SIM" message and the consensus is that this is not normal and the phone is not unlocked.
So the question for those who have their phones _successfully_ unlocked, was there anything in addition to Sprint saying that they unlocked your phone?
when sprint unlocked my phone? I don't follow?

You call them (or chat) and ask to unlock the phone to be used with 3rd party GSM carriers. That's what I meant.

I don't know if my phone has been successfully unlocked - but I can swap in a US T-mo Sim and it doesn't show an Invalid SIM message on my phone.
I only got an Email from InternationalDeviceUnlock <[email protected]> with the following message
Hello xxxxx xxxxxx
This email is intended to confirm that Sprint has successfully unlocked your Samsung Galaxy s4 Device. Please follow the steps below to unlock the device after you have the third party SIM:
Turn off device > Insert 3rd party SIM > go to Settings > More (tab) > System Update > UICC unlock. You will receive the update and it should change to GSM Mode.
Phone number: xxxxxxxxxx
If you have any additional questions comments or concerns please contact Sprint World Wide care 24/7 at 888-226-7212

So did the phone actually do the above?
it wont work on tmobile
tmobile is on different bandwidths when they say unlock they mean international not any us carriers and even if it did work you would only get edge no 3g or lte

no, tmobile and att bands are supported by the hardware.. but are blocked by samsung/sprint regardless of unlocked sim status. if we can unblock it 3G would also be supported. WCDMA band support on the Sprint GS4 includes 850mhz and 1900mhz... so that means 3G works just about everywhere for ATT... and Tmobile would have no AWS band support but would have 3G in areas where Tmobile has refarmed 1900mhz.
Again.. the hardware itself supports these bands... its just an extra block thats stopping us. I am working on the unblock for ATT/Tmobile.
And to the OP @obender, @jj14's post show exactly what Sprint sends when the device is unlocked. Other than that... go thru the steps and that's that. As jj14 also states.. he can pop in a tmo sim and gets no error... proving he is truly unlocked.

I had my phone unlocked, and I did the above as per the email I received. However it just said that the profile had been successfully updated, which was the same thing it said before it was supposedly unlocked when I pressed UICC unlock. It also didn't change to GSM mode automatically. So I wasn't really sure it had worked, but I was able to put in the AT&T SIM from my Nexus 7 and I didn't get an invalid SIM error.
When I went to Costa Rica, I was successfully able to use my phone with a prepaid SIM (GSM and HSPA/WCDMA). That said, I had to go into the Testing menu and force it to use only WCDMA, otherwise it would only use GSM/EDGE (even selecting WCDMA preferred didn't work... it would switch back to GSM pretty quickly). I also had to make a build.prop edit to be able to add an APN to use data. So you basically need root if you want to use data.

Be sure to let us know if at some point you do unlock it for T-Mobile/ATT - following you on twitter nowhoping to see a tweet at s ome point saying that you got it! Good luck!

You seem to be digging in the unlock for the S4, but are you just working on domestic, or also international unlock. Have anyone tried pulling all the nv items before and after the unlock?

I just recently got my S4 from sprint I had them unlock it for international use all the available networks now show up, but in regards to invalid sim msg I will not know till the end of September when i am out of country. and on a side note if you call Sprint before you own the phone for less than 90 days you have to go through a lot of loops but they will unlock it for international use. out side of that I am unsure as too how far the unlock actually goes.
will keep you updated as to my findings I will be trying a different sim card while over there

I picked up a SM-G900L version of the S5 and the clerk told me that it's unlocked and i'll be able to use it in the U.S. without a problem. Is there anyway to verify I won't have any problems (updates etc etc) with the phone once I head back to the states?
Also I rarely see any threads for the G900L version...

Pop in a Tmo or ATT sim and see if it works. I don't believe there is a screen or setting that shows "unlocked".
Edit: You will need to enter the correct APN for these carriers to get data.

hi on my s i tape *#0011# and down i see if its lock or not .perhaps helping
Yeah, for me, that's my way to check it, insert SIM card from different carriers.
there is no other way to test this, other than popping in a different SIM?
Greetings fellow telephony addicts - purchased a Boost Mobile Moto E w/5.1 (xt1526) because of apparent ease of ul'ing bl and rooting. True enough --
However since then I've been trying to get the device to allow use of a GSM SIM (USA/att.) Recently did it on a vzw (xt1528) no problem following instructions found here bit the xt1526 has beaten me senseless, going so far as to install cm13 in a totally illogical move. It works beautifuly, if you don't need calls or mms. Searched the crap out of the E forums with a couple of tips that did not pan out.
Anyone give me any hints /tips or even a nay as in "you dummy you can't to that!"

Boost / sprint xt1526 are locked so that us domestic GSM Sims are not recognized. To my knowledge, no one here has yet gotten around this. I switched from a sprint branded one to a USCellular, which is fully SIM unlocked out of the box, bootloader unlockable, and supports att LTE. Using it right now with my postpaid ATT SIM

Only thing I can think of is to flash the RADIO from a variant that isn't SIM locked and seeing if that works. It's a risky experiment tho... it could definitely brick the device in terms of ever being able to connect to a cell tower again.
Closest match is the USC 5.1 stock ROM's radio, which has the same model number XT1526, and is CDMA compatible, but that phone is also known to work on domestic GSM networks.
Double Thanks - Phone is useless to me as is so it's worth a go. Will report the results here.

I fell in the same trap, but you can still make the phone useful if you sign up for freedom pop or ringplus, i plan on keeping the phone as a backup and getting the N5X next week.

Weird - I installed the complete USC 5.1 stock ROM - Everything seems to work fine, but the system version and the broadband version coming up as Sprint. US cellular is not a Sprint MVNO I don't think, but it seems to be kind of a hybrid in terms of networks? No option for switching the network to GSM/LTE in the settings that I can find.
Not sure what I'm going to try next...

Did you flash the Radio/Modem too? If not, that's why the baseband comes up as Sprint.
Dial *#*#4636#*#*, phone info, change "CDMA/LTE" to "LTE/GSM/CDMA auto (PRL)". If you can't do that, follow the 5.1 instructions here: http://forum.xda-developers.com/moto-e-2015/general/how-to-verizon-moto-e-2015-gsm-network-t3098953 (change the 9 to a 10 for LTE/GSM/CDMA)
This will allow you to change the phone to LTE/GSM/CDMA mode.
Isn't the NON-HLOS.bin file the modem file? I did the keyboard commands and got the phone info and was able to change it but it didn't change anything, live or after a reboot - same thing. did the adb shell commands and the same
thing, cellular network settings grayed out. I put back the sprint SIM that came with the kit and it was fine and the network settings are available...hmmmm.
I greatly appreciate the suggestions. I'm gonna leave the battlefield and get dinner or my wife will call me mean geeky names

Putting this thread to rest
Spent the last couple of days flashing the E with rom after rom, particularly of GSM phones, ATT, TM, etc and their respective radio files. And not to my surprise the phone works fine with every one of then regardless of model XTxxxx anything, phone runs flawless, except for the network of course, which always remains Sprint.
I have to conclude, unless someone can prove otherwise, that the phone network part is either embedded in the chipset as hardware or a combination of hardware and software, or the modem files are somehow protected from being overwritten.
Was interesting and educational.
Thanks to those who gave ideas or suggestions, especially you Mr. President

Ok –*question. If I put Cyanogenmod 13 (Lollipop) onto the Moto E 1526 (U.S. Cellular version) –*will GSM work on it? I need to buy my grandma a GSM phone who doesn't live in the States & I want the GSM card to be easy plug in play for her.
I know that the U.S. Cellular version is the best because it is unlocked for GSM as well, but I believe XT1526's default radio is CDMA.
Maybe I should get a GSM sim card here in the States and switch it to GSM on CM13 (if this is possible) –*that way all my grandmother has to do is put the sim card in without any hassle.

The device does do funky things with the radio on first boot on a new rom. I've run several CM based marshmallow roms. There's no real issue, but you need to go through the non-adb method (using the network app) to get GSM working on every new clean flash. Typically this means pulling the GSM SIM before initial boot (when I don't, the radio keeps cycling through modes making initial setup very difficult), do setup on Wi-Fi, turn off radio, insert SIM, then do the process.
I definitely would not give the device to a non tech savvy person before doing this on a clean flash. Once it's done, you can remove and reinsert Sims without issue.

Yep, you got it. Actually, I don't think it's too picky about the order of operations as described in that thread - I've done this many times without referring to the thread so have likely done it "wrong" at times, and it still works. Basically, radio off (either via airplane mode or network app), switch modes, radio back on.
Just don't clean flash a rom without either access to Wi-Fi, or a locally installable copy of the network app.

Hey .. i am in Karachi Pakistan ...
i have seen this phone workingperfectly with gsm network until someone makes a factory Data reset ..
still not found out the solution ..
the devices arrived from china in working condition ..
FYI - US Cellular was bought out by sprint last year, so they are now a sprint mvno.
Did you try flashing the stock 6.0 ROM?
So just wanted to let you guys know at least this worked on my end. If you have the SM-G950U preordered S8 and using Sprint, you can edit MSL settings.
1. Go to diaper and type in ##3282#
2. Either view DATA or Edit
3. Type in '000000' as your MSL Code.
Don't know if you can really change too much but I'm going to play around a little.
Let me know if this is helpful to anyone or if anybody has any further suggestions or comments.
Worked for me also. Thanks for the information.

I got it still can't edit the APNS
Yeah not sure why we can't. However, interestingly if we try to access APN list via settings - connections- mobile networks - access point names, I can see a list of 7 APNs. I assume most are only used for OTA updates and if you set your connection. From cdma/LTE mode to global mode. If I then go into DATA Menu and edit mode and click on the APNs then I can only see 2 options (EHRPD or LTE) but I am able to select the one I want and change it. However, I do see that I don't have the option to add a APN. This might be a limitation when using Sprint as the carrier.

Well the thing is that I have a sprint Galaxy S8 with i bought "unlocked" to my surprise it wasn't I have ATT. So im looking to whatever i can t get this cellphone unlocked!!!! Since I don't have a Sprint SIM. I can't edit APNS on settings!!
Hmm well I figured you probably already tried this but earlier if I went to Settings- connections - mobile networks- network mode and changed to gsm/umts I was able to then click manual and search for network and connect to either AT&T or T-Mobile. Not sure if this Must be done first.

I went to Settings-conection- I don't have mobile networks here.
I don't know if you need to have a sprint sim for this. But right now I don't have any sim because Im using ATT and using a older phone to be able to have a phone!!!
Okay so I just tried this option. Go into the connection and network mode and change to automatic. Then had to restart. Once restarted I went back to network mode and changed to gsm. Then I went to network operators and searched for network. Got the error that it must kill data connection before searching. I selected ok and searched. Att and T-Mobile came up. I selected Att and it said it registered on AT&T. I don't have an AT&T SIM so I can't test. However, in the morning of I see my roommate I might be able to try his SIM.
Also you might have to select gsm mode and then do the ##3282# and edit mode first and then go into settings to change network operators. Not sure but it seems ##3282# edit mode must be done to unlock additional settings in the phone.

Don't have conection mode either. I'm thinking you have this enabled because you have a sprint sim in it!!
Did you buy the phone already activated on Sprint network? And also it is a G950U correct? The only reason I ask is because I think the G950U is unlocked but if it was already activated on Sprint, then you might have to factory reset the phone and have the AT&T SIM inserted to have AT&T be your carrier.

Did you buy the phone already activated on Sprint network? And also it is a G950U correct?

I don't know I bought it from somebody locally who said it was unlocked and yes it says G90U but when I insert the sim card it says invalid sim card.
Let me try the reset with the AT&T sim in it to see
When I first turned the phone on it never had the Sprint splash screen until it finished setting up and power cycled. That was the first thing I noticed. Also the phone should be unlocked by default bc this variant is exactly the same for the 4 major carriers. When I checked the firmware both CSC and AP it was the exact same as T-Mobile firmware.
Please let me know if that works. It is just a suggestion and there is so much confusion on this at least from my part. Not to mention not much info on the forum yet. If this works then it might shed some light on the G950U variant.

Did it still the sprint splash screen comes on!!! Waiting until boots full
Hmm hopefully it isn't a firmware issue. I'm not sure if there is an AT&T firmware up on samfirm.com yet

Does not work. Is says please provide the UICC that came with the phone. So apparently when you activate it with a provider it locks!!
Sounds like it might SIM carrier lock. I think the law last year stated that we have to be able to swap phone on any carrier in the US. There is a UICC unlock under settings and software updates but it wouldn't work for me. If I remember properly I had to wait about a month or two before they would let me UICC unlock it. On samfirmware there isn't an AT&T firmware uploaded yet. There should be soon. You could try to wipe and use the T-Mobile firmware as this is GSM and will at least be the network of roam for AT&T. Might at least allow you to use the SIM or at least activate on AT&T

Well checked on sammobile.net still nothing for the AT&T varian, but if you look at the S8+ they already have the firmware for AT&T

Could do it. I wiped the Verizon one but still the sprint splash screen come on so I don't know
I know this has other threads, but I wanted to post something that helped me get VoLTE working that none of the other threads addressed.
Quick background: new to TMobile, new to the 1+ brand. Rooted, stock. I could get LTE, but I kept getting kicked to roaming AT&T H+ or 3G, couldn't get VoLTE, and very slows speeds even when on LTE. Tried every APN combo, network settings reset, factory phone reset, tried every *#*#4636#*#* preferred network type...nothing. Chatted in to 1+ asking if I could speak to technical support. The response was the only way to fix it was to factory reset (which I had already done) and downgrade OOS. The newest OOS has the T-Mobile optimizations, so downgrading makes no sense! Needless to say, the whole 30 min chat was a waste of time and just a bunch of weak canned responses with no attempt to really help or figure out how to escalate me to someone with some knowledge of the APNs and settings needed.
Out of desperation, or since I had tried every other possible trick, I went under my T-Mobile SIM, Network Operators, and toggled Auto Choose and manually chose TMobile 4G.
Boom, full bands 4, 12 and VoLTE, and normal speeds! Carrier aggregation is even working sometimes.
I don't know why Auto Choose doesn't know how to grab 4G permanently, but everything is working!
Does anyone have any idea why this fixed it? Since I choose 4G, will I lose my ability to get 3G in rural areas? I don't feel like there was much info on how VoLTE is provisioned on the phone.
What's everyone's experience with the preferred network settings? I'm currently in LTE/UMTS, and I don't have the LTE/GSM option that apparently everyone else has...?
Also, does everyone else have as sporadic speeds as I do? One moment it'll be 40 down, next it'll be 6? I know it has to do with bands, but should there be a way to even that out a little?
Sidenote: I really like 1+ mentality about rooting and software, since I have to have a rooted phone, but this experience really soured my first impression. Plus their 1+5 is a major letdown to me. I don't think I'll purchase anymore 1+ products.
Feel free to correct any misinformation in my post.
I also have noticed when I try streaming, webpages or speedtests the little LTE+ carrier aggregation kicks in to combine band 4 and 12 and I get pretty good speeds. See screenshot
My speeds do definitely vary on Tmobiles network. Isn't an issue for me, everything streams fine, also i haven't had an issue with VOLTE since I got the phone in February..
I noticed when I'm in a roaming area, instead of roaming now, I completely lose service. I believe this is because I manually selected TMobile 4G as my operator instead of auto, which would allow the phone to jump to AT&T. Any ideas?
So still having problems, but only when traveling. If I have network operator on "auto" it'll select AT&T roaming, but then it'll just stick then and never switch back to TMobile, even in full strength band 4 or 12 areas. I have to reboot, and toggle auto for it to grab a T-Mobile signal. Very irritating. This also kicks the phone off VoLTE, and I've yet to get it back. Not sure if this is TMobile or the phone's fault. Tried everything I can think of. Any ideas?

Get a new SIM card

Excuse my ignorance, but what would a new SIM accomplish, technically speaking that is?
FYI, my wife's HTC 10 does the same thing. That would make two bad SIMs unlikely?

I've had same problem as yours, I went to T-Mobile store and told them what was going on. They switched my SIM card and problem fixed. I was told because my SIM was too old (4 years at least) that's why i was having such issue.

Gotcha thanks, I'll give it a try! What's weird is our SIMs are only weeks old....

That's what I've been thru and got fixed. Hopefully it'll work for you too
New SIM, no change
This phone has the features I want, and T-Mobile has the speeds I want, but this is frustrating to be kicked to roaming and no VoLTE....

Sorry to hear that it didn't work out for you. I attached couple of screenshots just to show you that it's been working good for me after I switched SIM card.
Edit: have you tried to create a new APN instead of using the default APN?
Edit 2: I can show you my APN if you want
Sorry, must have not been clear. I can get LTE, just not automatically after going into a roaming area. It just sticks on AT&T roaming until I manually go back in and select TMobile 4G. The problem with that is when I do need roaming to work, it won't because I have TMobile 4G manually selected.
Another problem is that I can't get VoLTE to stay very long, in fact i haven't had it for a couple days, despite me being in a very strong LTE area.
I appreciate your help
Edit: yes, if I could see your APN that'd be great!

Just create a new APN exactly as mine and see if it works
Hmm yeah that's the one I have too....
Btw, maybe I just needed to wait,, but VoLTE is working again, and it's reporting the correct IMEI (it wasn't before but TMobile told me that wasn't a big deal...I beg to differ because now my TMobile app is working whereas before it wasn't) Fingers crossed the new SIM did the trick! I'll know tomorrow when I commute to work and it starts roaming whether it'll reacquire T-Mobile and VoLTE
Quick update: I definitely have noticed an improvement in jumping off AT&T roaming back onto TMobile LTE. AND VoLTE is now sticking. But... I'm inclined to think it's something related to me not having my second Verizon SIM in. I have a company work number on a Verizon SIM that enables me to text and call from that number. Obviously data doesn't work but that doesn't bother me since I have TMobile unlimited on my personal SIM. When I insert my Verizon SIM in the second slot, my IMEI number changes in the testing menu, but not my settings info! What the heck? The IMEI number identifies the phone and shouldn't change...I thought? Very confused why part of my phone retains the correct IMEI and the testing changes. I instantly lose VoLTE and my TMobile app fails to authenticate.
What is going on???
UPDATE:
I popped my Verizon SIM in again (slot 1) and it's reporting the xx...15 IMEI (correct one on my T-Mobile account) and the T-Mobile SIM (slot 2) then drops to xx...07! I'm so confused! I thought the IMEI is NOT supposed to change because it identifies the device?? The ICCID is the SIM number? Why is Verizon SIM screwing this up?
