Im coming from a S9+. Its been two years since i played around with flashing Fw etc so my memory is a bit hazy.
Short question. If were to put a USA sim card in my Canadian S20+. Will that cause a factory reset? Or does the canadian fw does not have the CSC files for the US carriers so it should continue to function as is, but potentially with missing features for the US carrier? Does that sound about right?
Thank you
It will work just fine, if the device is carrier unlocked. I have an unlocked G981W from Bell, and an ATT sim worked no problem. No device reset etc required.
Also have tried a Rogers and a SaskTel sim without issues .
Cool thanks.

Hi! first poster here.
I've just got this phone wich was recently unlocked from TELCEL MEX carrier. The weird thing here is that the phone work flawlessly with any domestic carrier sim cards, but not with my US T-Mobile sim card.
I've test this T-mobile sim card with other unlocked phones (Galaxy S4 i9500 and Alcatel Pop) here in México without problem, but in the S4 above mentioned asks for sim unlock code.
The cell phone is SGH-I337M with KitKat 4.4.2. and firmware CSC code TCE
Thank you very much in advance!
This may be relevant or not.
My previous phone was an HTC Desire S on O2UK.
O2UK give you a free unlock on all contract phones after 6 months and send a code by email to you.
Any time I tried changing sims to a different carrier it asked for the unlock code, except when it was Tesco Mobile UK.
It may be that the original carrier requires you to input the unlock code for anything other than certain providers.
I tried to get an unlock code for my I9505 LTE but they said it was factory unlocked so can't speak about the phone specifically but with the Desire S, also on O2UK, had a similar issue.
I've got the pin code
Thanks for your input, sure it's relevant.
I have the unlock code for the T-mobile sim card, but of course it's not recognized by the phone (or sim card?)
In the other phones tested the process was straight forward, just inserted sim, boot up and voilá.
Went to the Telcel's service center but the person there confirmed that it's unlocked.
I'ven reading about a "Regional Lock" of some Samsung devices, but i realy can tell if this the case.
Anybody else having this kind of issue?
Region locking I don't believe has anything to do with this. When the phone was unlocked, the region locking should also have been removed.
So my S6 had an unfortunate trip in the lake, and I'm going to resort to my sisters old S4 (I owned one too, but I totalled it).
Mine was rooted and had GPE loaded on it.
My old model was an i9505 and noticed that my sisters is a i9507 which is a strange variant (assuming its 4G+).
Anyway, when she had it, the phone constantly overheated and would constantly reboot. We returned for repair many times, each time showing no signs of issue.
What I would like to know is;
Would i9505 roms suit this phone? Or would I have to make do with stock.
And secondly, I am with telstra and the S4 is with virgin (OPS). Is it as simple as flashing a i9507 ROM from telsra on it, or do I have to do something else? This is for the CSC of course.
Is the phone sim unlocked? I recommend sim unlocking the phone before flashing any ROMs, especially custom ROMs as the unlock code needs to be entered using a stock Samsung dialler.
CSC doesn't really matter if the phone is sim unlocked.

Hmm stock firmware is only 5.0.1 and not for the carrier that I want. It's been so long since I've modded (since I've had stock S6 since I bought it). Can I change the CSC on that rom, or would it be locked to Optus.
Anyway I've put in my Telstra sim and it seems to work for the moment, picking up the telstra network and changing the APN's to telstras (maybe there is a CSC in the phone for TEL too?).
Just would like to know now if I'm able to use a GEL or AOSP rom for the i9505.
Thanks for the response.
The firmware should not matter. The CSC files are a customization of app for a particular carrier. There are 3 carriers in Canada (Rogers, Bell, Telus) for the s4 and I can cross-flash the firmware with no problems. I would be surprised if the phone can't work with Telstra if it is unlocked.
According to these specs, the 9507 uses a snapdragon 600 chip which is the chip used in the i337m and 9505: http://www.gsmarena.com/samsung_i9507_galaxy_s4_with_s600_spotted_in_glbench-news-6571.php
Hello everyone,
yesterday, a family member gifted me an s7 from the USA (SM-G930P). He bought the phone off SPRINT as a SPRINT unlocked version, and, of course, because I live in Europe and want to use the phone with a European SIM card I have the "hands free activation" mark that is sitting on the top left edge of the display. I also noticed some changes, for example the "mobile data" toggle is nowhere to be found and also I don't have the options to choose the network mode (2G/3G/4G). I love the phone and I also would like to keep using it, I only need some answers from you guys.
My first question is, if the phone will actually let me use 4G network with my European SIM card, or will I be limited to 3G?
My second question is, If I can flash an international firmware for another carrier and another country on the phone, and if so, will I have the advantages of that firmware, like the Mobile Data Toggle??
Thank you very much for your answers.
If you install the 'Network' app you might be able to change the network type.
In general you should be able to use an unlocked P variant with a foreign SIM but you may have to activate with a Sprint SIM first.
You can't flash the international version since it's Exynos and the P version is Qualcomm CPU.
I am not sure if this model has Samsung region lock which is another thing to consider.
If I was you I would try to flash the U firmware (US unlocked) as it has the most support for international 4G bands among the Qualcomm US models. It also doesn't have all of the Sprint bloatware on it.

Thank you for your reply. I am currently using the European Sim from my carrier and I have no problems with it. I managed to get rid of the Bloatware by using Package Disabler Pro, but it still sits there somewhere on my phone. So far, the phone is working very well and other than the bloat sitting on my memory and the lack of LTE, I have no complaints.
Can you tell me if someone has tried to flash the U firmware on a P model with success?

Could you tell me how you did it, or link me a guide??
I had bought an unlocked Sprint galaxy S7 (930P) off ebay which died on me. Got it repaired from the service center and they sent me a locked device instead. The phone is currently on Software Version - G930PVPS4BQC1 and the hardware revision is Rev 0.6. I'll be using the phone in India and have a few questions.
1. I need to get this SIM unlocked from a service online. Does anyone know of a reliable place to do so?
2. If I flash the U Rom on it after unlocking it, will I lose the unlock? (I don't mind downgrading from Nougat to Marshmallow)
3. Should I unlock first then flash the ROM or flash the ROM first and then try to get it unlocked?
4. Will flashing the ROM directly unlock the phone itself?
Please advise.
...
you could try gsm zambia to unlock your phone it works i tried it myself a few days ago, also after my phone got unlocked i flash the U firmware/rom and the unlocked remained. so you should unlock your device first then flash the U firmware :good:
PS. if you one nougat better to downgrade if you can do marshmallow so when you wont have any issues flashing to U firmware. :cool

I would like to ask @wujke as he is from the same country (and maybe same network as i am) one question.My carrier (from which i bought this device on contract) doesnt support official updates above kitkat.As i updated this phone to lollipop (different modem and firmware) is it possible that i broke a sim lock from my carrier.last week i was abroad and i used sim card from that country with no problem.Since i dont own any other sim cards i would be grateful if somebody could answer this question.Thanks in advance
Everything is possible, maybe it wasn't locked at all. In Telenor I've seen everything, from unlocked phones to locked without possibility to unlock bootloader.
Hello guys. This is my first Samsung device. It's network locked here in the Philippines and I flashed UK firmware to get Nougat update. Since thre is an official update available now in our country, I flashed the firmware downloaded from sammobile with CSC SMA (philippines Smart). The problem is, SIM 2 is not working for a different SIM card (ex. Globe). Does anyone know how to fix this issue? Before only SIM 1 is Network locked and SIM 2 is openline. Now they are both Network locked.

As far as I know, Dual SIM phone has issues when trying to unlock the phone. they are problematic and sometimes they refuse to work. I recommend you take it to Samsung assistance, maybe they can do something with your firmware and make the phone work again.
