I bought an SM-G920S while on vacation in Korea for a good price, unlocked, but failed to do research on the supported bands. So now when using a local T-mobile sim, I'm only getting 3G due to the missing bands. I've rooted the device and have customized many things but the ability to access SK Telecoms hidden menu errors out when trying to enable additional bands in the CROM menu. Our phones can be enabled on all bands, but if there is a bootloader installed, it's impossible to change. I've done a search here and online and can't find a well known bootloader removal. I'm waiting for cyanogenmod to come out to completely wipe the ROM. SK Telecom has so many bloatware that it's eating up the battery. Luckily with root, i can kill and remove background services.
Thanks any help much appreciated.

I searched the Verizon Galaxy S3 forums and could find no discussion about the global capabilities of this phone. I had understood at purchase (pre-ordered) that an OTA update would be coming soon to turn on global capabilities. I have seen nothing yet. I have called Verizon, gone to local store (useless), contacted Samsung tech support both online and via telephone. Everyone just says they have no idea.
So, if I have rooted my phone and unlocked the bootloader, is there a way to turn on global capabilities? Or even easier, can I just buy a SIM card from a European provider and insert and it will work?
I appreciate any input on this. I am new to using a smartphone in Europe but I can't give it up now for even two weeks.
Just wait for the ota. Im due for a dominican republuc trip in 50 days. If i dont get the unlocking OTA before my trip im raising hell.

I want to know what people who live on/near a border do? If you live in US very near the Canada border, how do you stop your phone from roaming back & forth and bending you over on "international" charges, even though you technically are in the US.

Thanks for responding. I did find this thread a bit after I posted. Working through the steps.
Just a quick question on this topic. I've received the 4.1 OTA update from Verizon for the Galaxy S3. This update was supposed to bring global roaming capabilities. My question is, what does this mean? I know the thread linked above allows a Galaxy S3 to use other 3G networks but that involves rooting and complicated setups with APN (which, while I can certainly do, I'd rather not).
So, what does the default 4.1 configuration on Verizon get me? Can I go to, say, Japan and pop in a 3G SIM? Or is "roaming" simply roaming on any CDMA network? Is Verizon going to charge roaming fees?

I had a similar question and called Verizon. They confirmed that the 4.1 update unlocks the sim so that you can use any carrier overseas. However, if you need to modify APN's, good luck. There is no easy way to do that I've found without rooting. I'd rather not root my phone. I'm going to PAris and Rome in April and was hoping to use a sim card from iphonetrips. They have the best deals for unlimited data depending...
I'm trying to find out if what I would like to do is possible and if it is, how I would go about doing it. I've already spent hours scrolling threads on here looking for information. I feel like I've scratched the surface but I haven't found exactly what I'm looking for yet to confirm whether or not I can accomplish what I'm attempting to do.
Let me start at the beginning. I own a Samsung Galaxy S5 LTE-A (SM-G906K) and I recently switched carriers from AT&T to Verizon. At the store I was unable to get the sim card to work with my device. I also checked the IMEI on Verizons website and it said my device was not compatible with their network. Out of necessity I picked up another phone. I know Verizon is or has been a CDMA network but from what I understand, they are transitioning or have transitioned to a GSM network. The phone I purchased at the Verizon store; a G360V; does not work without a sim card, which seems in line with any other GSM device. Furthermore, I tinkered with service mode on my G906 to get a LTE connection a while back and I saw a CDMA option in the menu. Out of curiosity, I checked out service mode again. Sure enough through navigating the main menu in service mode I can access numerous options containing "CDMA" in the title. The problem is I don't know what any of these options do.
I would like to know if there is any possible way to get my g906 working on Verizon's network. I feel like this would be more or less easy to do with an American device but since I have the Korean version, the model I own was skipped when non-Verizon devices were certified to be on the network. I assume this because apparently quite a few individuals have brought their own device on to their Verizon plan.
So my questions are: Where should I look to get more information about getting my Verizon sim to work on my g906? I see a lot of info about switching from Verizon to a different carrier but what about the other way around? Where can I get detailed explanations of the service menu options and their functions?
Thanks in advance
Hi, thank you for using XDA Assist. The best place to ask is in your device's specific forum here, http://forum.xda-developers.com/galaxy-s5 Also see this, http://forum.xda-developers.com/galaxy-s5/general/sm-g906s-k-l-owner-thread-t2807639 This is probably the best place to start.

So something weird has been happening since purchasing my mint conditioned note 3 on Sprint. Every time I was inside my home, my note 3 would lose LTE and stay on 3g. I was looking for answers and not finding a single thing. I came up with a solution myself and here is where the explaining begins. Be careful when purchasing a phone online as some are international phones (which we know). I happened to purchase an n900p note 3 model and it was actually made in China but my signal radios were set to Japan. If you are in the USA and using Sprint then do the following:
-Download from the play store an app called Samsung phone info
-After the install is complete open the app and open the menu on the left side
-Select Secret Codes
-Scroll down to settings and select Launch 0
-Choose Phone Information
-In the upper right hand corner there are 3 dots, choose radio baseband and select USA from Japan
-Enjoy LTE

Are you rooted? Or on the default ROM for your device? The problem could be sprint uses CDMA not GSM, GSM is for devices without sim cards but I think is used on sprint for the sole purpose of emergency calls

But do you still have IMEI and Baseband version?
(look for the Baseband version and IMEI in the Phone INFO app).

the phone is rooted and running close to stock tw 4.4.4 rom.
true that sprint is a cdma carrier. but the n900p has all the gsm basebands which my carrier provides.
also phone has been internationally unlocked using sprint unlocker. (ssu.apk.)

baseband is nk4 and my imei number is shown which starts from 99.
so i think everything is pretty normal here.
i am just concerned about the phone not activating and it refuses to register to any network. i've tried 3 different indian carrier sim cards.

The phone might not be compatible with that specific carrier or you might have to take your sim card to the carrier and have them activate it but who knows.I took mine to Sprint and the guy asked me where I got the phone, I told him online. The problem with me having a Japan radio baseband set as default my LTE signal gets lost when I go in a building but when I'm outside, it picks back up again. If I switch the radio to USA I get 4g but then can't send/receive MMS. After a period of time on the USA baseband, it will completely lose signal and show up a black empty service in my status bar

Not if the sim card isn't working I would contact the carrier and see if they can get your sim card entered properly for service to your device

Hi guys,
I have a white Galaxy S6 Edge 64 GB Sprint model, SM-G925P and lots of trouble. I did not buy it from Sprint, as I'm not from US, instead traded my black 32 GB SM-G925F for this model, which is the international model. Thought that 32 extra gigs would not hurt and that the white one would be less off a fingerprint magnet.
Unfortunately, during the trade, I did not pay attention to a very important aspect: mobile data. I checked voice calls, camera and wi-fi as well, thought that everything should be fine. Mobile data is available only while accesing the settings and does not show while sliding from the top of the phone for the control panel.
As I got home, I discovered afterwards that I cannot make the update from 5.0.2 to 5.1.1 and that I cannot change the language from English to Romanian. The next day, I took the phone to a GSM service and they made the 5.1.1 update and mobile data work. I still can toggle it on/off only in the settings. The big issue is that I can use only 3G mobile data and that upsets me a lot. Of course, the guy that I made the trade with isn´t anymore to reach. Please let me know if I can do anything about 4G. I am really pissed off right now. Thank you very much!
Hi,
I'm also wondering if there's something possible. I already tried QPST and QXDM for enabling more bands but it didn't work. I guess it's something with the modem. Since the 925F uses a different chipset than the 925P it's not possible to use that one, but I found out that the G9250 has the same chipset as the G925P and supports an extreme amount of bands (more than the 925F). But since our bootloader is locked it's not possible to flash the modem. And even then there could be a lot of problems. So we have to enable the bands in the modem.bin. But that's quite hard and I still haven't found out how to do it, but it's our only hope. (G9250 Bands: http://pdadb.net/index.php?m=specs&id=7836&c=samsung_sm-g9250_galaxy_s6_edge_td-lte_samsung_zero)
Thank you for your answer mkalter,
I am by no means a developer and never rooted a phone, but if there is any solution that won´t brick up the device, I'll gladly try it. It is very upsetting to know that I cannot use 4G on it just because a provider doesn´t want so. Had to learn the hard way to triple check a phone when trading it.
I just solved the issue by selling the phone. Mods can close the thread.
Hi, I got a Samsung Galaxy J7 Prime off Amazon, problem is that I am currently in the USA & using a T-Mobile USA line, the device is unable to detect the carrier's 4G LTE or 3G Networks, it only picks up 2G (Edge) networks. I have switched sims a few times & toggled the 4G/3G/2G & 3G/2G auto connect options, but nothing seems to work. I was informed that perhaps the device is not compatible with this carrier. Does anyone have any experience with this issue? As I need fast internet on my phone & can't afford to purchase a new phone at this point.
Thank you
According to this Samsung SM-G610F Galaxy J7 Prime TD-LTE Compatibility on T-Mobile (United States) Mobile Network
you should be able to at least access 3g.
I don't know if its possible to change the LTE frequency band on the J7 Prime via Service Mode / Secrets Codes
Something like this Change Network Bands on Any Samsung Phone Without Root
*#0011*#, key input: Q 0000
Then navigate through the menus and look for bands and find t mobile bands
Hi, unfortunately, this didn't work, can you explain a bit more how I should do this?
Thanks.

If the codes don't work straight away, you'll need to enter Service mode.

Sorry for the delay, final projects for school are a pain.. I would start trying in a trial and error fashion, any and all dialer codes for your phone. BUT, u must be on stock for any to work. Find a guide and start punching buttons. Once you get into service mode, u will need to locate service bands and switch them to LTE that are within t mobiles service structure. Usually around 800 and up. I hope that helps. And good luck, I tried this for 2 months with a note 4 and couldn't get very far. If it's unlocked, sim and Carrier unlock, it should be easier. Also make sure the imei isn't blacklisted. Swappa allows u to check. All of these things must be done concurrently with the proper band selection. Good luck and just stick with it.i actually got mine switched from a sprint device to a t mobile, but unfortunately the device only works for 2 min increments due to a device financing block the previous owner had still. So it's sitting in my drawer of a smart phone graveyard
