Hey guys,
I tried searching on the topic but I'm hoping for more information specific to this phone.
I'm traveling to Germany in September. This will be my first time out of the country. I just called Sprint and requested for the phone to be unlocked for international travel. Since I've had the GS4 less than 90 days, I'm told this process will take a few days.
My questions are:
Now that my phone is unlocked, I can use international/locally bought micro-SIM cards, correct?
If I use these SIMs, will I still be subject to Sprint's high usage billing or will it operate entirely independently of Sprint's service?
If I flash a ROM, should I stick to the TW-based variants to ensure international capability? Or is it safer to leave the phone entirely stock until my trip is over?
If you have any tips and tricks for traveling (best SIM card, how to save money, the ROM you used while traveling, best apps for using minimal data, etc.) please do so! I appreciate your advice, everybody.
Thanks

If you lucky and your unlocking will go through without issues that some of us here are having then you should be able to use any non-US sim cards while outside the US. You will be subject to those carriers charges only. Just don't forget to turn off CDMA roaming and switch the phone to GMS/UMTS mode.
I cannot comment on the ROMs though.
I'm currently delpoyed with the military. Had my gs4 remotely unlocked and I now use a rebelphone sim card for my local area. Just turn your phone to gsm and I turn off data because its not included in my rebel phone package. Should be all good to go once u get that done.
Oh and I use blue kabans ROM

Is it possible to use a US sim card from another carrier in the US to check that the phone has successfully been unlocked before traveling? Sprint's told me that they unlocked my phone, but I want to be absolutely sure before I step on a plane in two weeks. I also have an update procedure to unlock the phone - I'd like to do that here in the US before I leave so that if there's any problem, I can work them in advance.
Thanks for moving Kenny!
Kate, from what I've been reading, under no circumstances will Sprint allow the phone to connect to a US GSM network using a T-Mobile or AT&T SIM card. I think this is analogous to "unlocking" the phone from its carrier, which carriers do not tolerate.
Buck, I will look at rebel phone among others. It seems data will be expensive, no matter what SIM card I choose. I expect things like Facebook updates and photo uploads should wait until I connect to wireless at hostels or my friend's place.

I'm in the same boat as you are, from what I could gather from forums and Sprint itself, the answer is NO, you cannot verify that you phone was unlock while here in the US with _ANY_ SIM card.

Hey obender, when you use international SIM cards, you lose your phone number for one they provide, correct?

Yes, that's correct.
And does the phone need to be rooted? It sounds like maybe not for voice, probably for data? I will want both when we go to Spain in a few months. I don't have the phone yet but plan to pick one up this week - love my S3 but I can't use it internationally, and I don't think I can go back to my Photon for the trip.

People report issues with data but according to sprint once it is unlocked it should work just fine both gsm voice and data, no rooting should be needed.
You can verify your UICC(sim) slot is unlocked by sticking in any "non-Sprint" sim card... if you get an error saying "Invalid Sim" then it's not unlocked... if you see no error.. you are probably unlocked. You can further verify this by going into About Device > Status and seeing if it's reading the ICCID of your new sim card.
You can test this with domestic sims too(ATT/Tmo etc).. though you will not get service due to Samsung blocking them. But yes.. the phone will read the ATT/Tmo ICCID if unlocked.

According to sprint what you just said is not true. It should show "invalid SIM" all the time while you are in US no matter if you unlocked or not.

Hi,
I got my sprint s4 unlocked by sprint for international use. I've got a europe orange sim, and when I put it in the phone, I don't get any error msg. (BTW, when I leave the phone without any sim card, it shows some small icon on top saying I'm missing a sim, also it won't let me go into network settings..) is it how it's suppose to be when Sprint unlock the phone for 3rd party sim (international) card? meaning If the phone was "unlocked" i would have get some error msg. saying the device "Can't access" the sim card etc.?
Thanks!

The error message would be the same small icon but it would just say "Invalid SIM", but this is just on my phone that was supposedly unlocked by Sprint, I cannot confirm that it actually works with non US SIM card since I haven't had a chance yet to travel outside the US. Your phone can be unlocked as well or not, you, unfortunately, have no way of telling this until you travel outside the US and try it.

Alright, If it says invalid sim after you put international card in it's definitely not unlocked. Me and me friend got the phone on the same day and called sprint about 100 time to get the phones working. After sprint told me and my buddy that phones are unlocked, we put it German sim card in and it said invalid sim, but sprint said it will change when you go to Germany. So i didn't believe them and called them another 100 times till about mid June I talked to some supervisor and she said that phone is unlocked. So I put it my German sim back in and it sent me an SMS about the rates of that German service in USA. After that my friend called those assholes another 100 times and they assured him that it will definitely work even though it says invalid SIM. Long story shor... we get there and he is screwed for 3 weeks. Even more so, he was willing to pay $10 per minute to roam in Germany with Sprint... NO SIGNAL ANYWHERE... AND my data did not work with different sim card. only calls and sms. Later i found out that it could be fixed by going to a local branch and downloading something but it was too late. SO Sprint sucks.
Here's the email I got upon requesting the unlock:
Hello Torrance,
This email is intended to confirm that Sprint has successfully processed the unlock request for your Samsung Galaxy s4 Device.* In order for the unlock to be completed, the device has to be connected to the CDMA Network or Wi-Fi connection for the update to finalize.
*Once the update has been completed, 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: XXX-XXX-XXXX
*If you have any additional questions comments or concerns please contact Sprint World Wide care 24/7 at 888-226-7212
*Thank you,

What version of the firmware are you running, is it the latest OTA MF9?

Sprint doesnt know what theyre talking about half the time. that is incorrect info.
no matter what sim you put in... if its PROPERLY unlocked... then you wont see a "invalid sim error". even att/tmobile.
if you put a sim in and it says "invalid sim" then the OTA sim unlock was not properly done and despite saying unlocked in sprints system.. it's really not.
I have both a sprint gs4 and sprint htc one. it's exactly the same on both.
This is my first android so please excuse the lack of experience with it.
I am using a Verizon Galaxy S5 with an AT&T sim in it. I got data to work after entering the AT&T APN settings and everything else is working except for incoming phone calls caller id format. Incoming calls are showing up as +-xxx-xxxx Example: +714-555-1212
If that call is from someone in my contact list it will not be identified. If I call back that number it will fail as it is assumed to be an invalid international number
I called AT&T support but they refused to help me stating that I am at fault for not using an AT&T device.
I have rooted the device using towel root and removed all Veirzon blotware.
I also installed PreFixer and it works sometime but I prefer to find a permanent solution if possible.
Question: is it possible to convert my Verizon S5 into an AT&T one by flashing it and installing an AT&T image? or will that brick my device?
Does anyone know how to fix this issue?
I appreciate your replies.
Hi Folks,
I am switching from an iPhone to S8 and noticed this annoyance. I spent 3+ hours setting up my S8 and proceeded to insert my SIM. After which, it totally erased my phone! I googled around and found out that this is apparently a "security feature".
I'm wondering if there's a way to disable this "feature"? I would want an option to pop-in the local sim when I am traveling abroad.
Thanks for your help!
I believe this only happens under initial setup or after a factory reset. When you insert a different sim from now on it will not reset everything.
Link to info you found on Google? So need to stick sim on it before we boot up if we're switching from say iPhone to S8?

Yes, definitely insert your sim before you do anything.

After initial setup are you allowed to swap sim as you see fit? Have a iPhone I'm going to share duties with.
Did you have the Canadian version? I saw this in S7 that was sold in Costco. Due to the unified rom, the first sim you put in will wipe the phone and configure it to that network.
This happens because when the SIM card is inserted, its carrier is detected and the phone switches from a generic CSC to the CSC of that carrier. Changing the CSC on a Samsung phone always results in a factory reset.
It is one of the reasons that carrier employees are supposed to insert the SIM card into the phone before giving it to the customer in the store. For those who receive their phone by mail, unfortunately there is no warning.
A good rule of thumb for Samsung phones (and probably a good idea for all Android phones in general) is to always insert the SIM card before doing any setup of any sort.
Yes, I have the Candian version and I'm with Koodo. As some of you pointed out, the restart indeed locked my phone. I can pop in another sim no problem now, but the phone prompts me for an unlock code.
A warning for mail orders would have been nice. But, such is life.
I also had this beautiful experience. I have not tried another SIM and have to admit I'm very hesitant to now, until I figure out a good backup process, now that I'm root-less. Did you try a SIM from a whole other carrier?
Edit: Sorry, misread and confused with my own experience. Unlock code = because you tried another carrier, right? I picked up elsewhere that the phones lock themselves to the first carrier they pick up, so you now need to get an unlock code from your carrier.
Geebus, I can't say I don't find this a bit annoying, I bought an unlocked device to avoid things like that. That's what you get for not researching, I suppose. :silly:
Edit 2: To impart a bit of what I found for other readers (since there aren't many threads about it, from what I can tell):
- Snapdragon phones since the Galaxy S7 and S7 Edge come Region Locked, not just carrier-locked. A region lock is to combat grey market reselling, but it's not so bad; just place a five-minute phone call in the region the phone was intended for, and that constraint is gone.
- Next, carrier SIM lock codes are not new, but I guess I was surprised to find that my direct-from-Samsung device will lock itself to the first carrier it attaches to. You can get an unlock code from the carrier (especially if you are leaving/moving, or the contract is over, for example), or via third-party service for around $30 USD or less.
If anyone has evidence or experience of the contrary, by all means let me know!

This is correct. It is done this way so that only one set of firmware is needed for the entire country, despite us having almost a dozen different carriers. It would be too much work for Samsung to have to tweak each new firmware update for each individual Canadian carrier, so they put them all into a single package.
All SM-G955W units use the same firmware and said firmware contains the CSC settings and 'bloatware' of every Canadian carrier. The pre-installed firmware does not install any carrier bloatware; those apps just sit in waiting, hidden in the firmware. Once a SIM card is inserted for the first time, the phone detects said SIM card's carrier, reboots into recovery and 'updates' by locking itself to that carrier and installing that carrier's bloatware. That change is written permanently into the phone's internals; from this point on, any time you factory reset it will go back to this state, with that carrier's firmware installed, even if you have subsequently unlocked the phone and have a different carrier's SIM card inserted.
When you see firmware downloads for a Samsung phone and each one is listed from a different carrier, that is actually irrelevant. The resulting firmware is identical and the phone will take whatever settings, CSC, and apps from within the firmware and install according to which carrier it was originally locked to (even if it is now unlocked).

How does this affect a device that was a carrier device but flashed to the U1 firmware? Or, alternate question: I flashed 950U1, so if I need to factory reset, will it revert to Verizon's branding?

It will factory reset to whatever the default is for the currently installed firmware.
Samsung phones from the US use a different firmware for each carrier. What was covered in this thread mostly applies to the Canadian firmware, which is just a singular firmware for all carriers throughout Canada.

Thanks for the reply. It's nice to know Verizon won't be coming back on factory reset.
Maybe it's a carrier thing. I factory reset my devices when I first get them and don't put the SIM in until I get my Samsung and Google accounts set up the way I want them. For my Exynos S8+ I had it almost completely set up before I went to AT&T to get its SIM cut. Whenever you remove a SIM from a phone where its currently being used you'll always get a "SIM removed - restart required." But it's a normal restart not a reset.

If you purchased unlocked from Samsung Canada they included the unlock code and IMEI with the shipping notice email. The phone locks to the first carrier then you put in the next SIM and use the unlock code from the shipping order. It didn't reset anything when I used a Rogers SIM to unlock from Virgin.

Is there any way to flash out the settings and apps from the original Sim/carrier?
I.e. im going from Rogers to Freedom mobile and have factory unlocked my phone with a code; can I now go from a rogers branded phone to a Freedom mobile branded phone or more preferably an unbranded version and still utilize all the functions of Freedom mobile such as Wi-Fi calling?

Sorry for the late reply. I didn't get an email notification about this post for some reason...
With root access, you would normally be able to remove these apps from the system partition of the phone, but on an unrooted Samsung device, the best you can do is to disable those apps. Once disabled, they are completely dormant and you can go about your business as if they aren't there. The bloatware from all Canadian carriers is baked into the firmware and on every one of our phones regardless, so it's not like you could truly get an "unbranded" Samsung phone in Canada. At best, these apps are hidden. They are not taking up space in the user partition, so it's not like deleting them would free up any usable space anyhow.
As for WiFi calling, my understanding is that carriers that support WiFi calling have to flag that IMEI to allow WiFi calling on their network. Furthermore, it seems that the carriers only initially flag their own phones (i.e. the ones you buy directly from that carrier) and refuse to add devices by customer request. I've read that some people have had luck calling their new carrier and asking for their ported phone to be enabled for WiFi calling, but it appears that the vast majority of people are denied. So I can't really say whether or not you will have any luck enabling WiFi calling after bringing a phone that was originally from a different carrier. If I had to wager, I would say that it wouldn't work as that seems to be the general consensus.
My "unlocked" Canadian SM-G955W Galaxy S8 is currently set on the FIDO network, since it was the first SIM I inserted into it.
I didn't mind too much about the bloatware: they're easy enough to disable.
I was a little irritated that the FIDO firmware disabled the "data" and "wireless hotspot" quick tiles, but read of a way using adb to make them available; but that needs to be done again after every firmware update.
But now, I'm pissed to discover that the FIDO firmware removed the option to do Bluetooth tethering. What? That's what brought me to this thread, searching for a way to have a truly unlocked phone.
So there really is no way to do this without rooting? What would happen if I flashed a US firmware? or UK?
Thanks!
You can change the csc to the unlocked variant xac, Dial *#243203855# in the dialer. But this will wipe your device.
Ok, I know this will be long, but I'll try to keep it short. Thanks again for your help.
I have an s7 sprint phone, after calling for two weeks and hearing the same tune, they unlocked my phone. I switched to tmobile and have a loaner phone even as of now because of stupid sprint. When I put the tmobile sim card in it says invalid sim card. So, I go to sprint and they said yes it is in fact unlocked. The guy seems really he wants to help, He can't get the t mobile sim to work also, matter of fact there is no options for network apn or nothing with the new t mobile sim card in. You have to put in the old sim card from sprint and there is the options. He even tried to some how change apn there on the spot by swapping sims while the sprint sim gave him options. He typed in all the t mobile info from t mobile site and it says unrestricted network. So he said its prob. sprints software locking the other networks. He said t mobile will have to flash it with their software. I go back to t mobile they have no idea what flashing even is. Unlike the sprint store they don't have a tech room with workers dedicated to working on phones.
SO, basically I'm trying to say my phone shows unlock on their side but i'm not to sure if it's showing it on myside. I can't use my phone at all i'm paying t mobile loaner j7 phone and stuck with an almost brand new s7 that either side has no idea. T mobile says its not unlocked over and over, sprint is saying it is unlocked.

I have a Galaxy S7 N930P from Sprint that I use here in Canada. I ended up flashing the unlocked N930U firmware (the Sprint variant), and all works well now. No Sprint bloatware, full access to my APNs again, unlocked bands, etc. I had to get the new firmware from SamFirm (or Sammobile), connect phone to computer via USB, reboot to download mode, run odin, then flashed the BL, AP, CP, and CSC (not the home CSC...the other one) files in the firmware's .zip using Odin 3.12.7. Worked for me, and sounds like something that might work in your case too. Worth exploring at least
Try flashing the unbranded firmware or if you moving to T-Mobile you can flash the T-Mobile branded firmware too.

First off, changing the firmware will not sim unlock the the sprint device, if you do flash to say a tmo branded firmware you will basically have a tmo branded device but still locked to Sprint. same thing applies if you flash the U firmware on a locked sprint device.
It's best to first have sprint unlock the device remotely then flash tmo or u firmware.
I've been on AlphaOmega ROM and want to revert back to stock as I'm selling the phone but I'm a little stuck. I've downloaded what I thought was the correct ROM
VS99520c_01_1110_ARB00.kdz (region VRZ)
and then tried
VS9951AA_01_0122_ARB00.kdz (region VRS)
The reason I'm stuck is I'm getting a notification saying Verizon Wireless does not recognise my sim. I'm in the UK (imported from Hong Kong) and quiet happily have used the mobile network data & voice on various providers though probably not as well as a phone intended for the UK market. It's my own fault for not backing up the original ROM I know :crying:
The other thing is and I'm not sure if I'm imagining this but I'm pretty sure when it used to complain about the sim which it would after every reboot it would say Verizon and not Verizon Wireless and it would still manage to pick up the local bands. Now I'm getting nothing, nada!
So any pointers would be appreciated :fingers-crossed: Am I using the wrong ROM?
