Sim lock and bootloader - Samsung Galaxy S9 Questions & Answers

Hi!
I've had my Galaxy S9 (SM-G960F) for about 2 weeks, loving it so far, but I'm a bit worried about the Sim lock thing so I have a few questions and I'd appreciate some answers and they're as following:
1. Since it's the Exynos version. Is it possible to use a Sim card inside the US (any carrier)?
2. Will it be fully functional (data, SMS and cellular calls)?
3. If not, is it possible to "unlock" the phone?
4. How to check bootloader status and if it's locked/unlocked/unlockable?

[Q] Sim Unlock for Travel with Rooted DINC 2

So I have been googling for answers for a few days now and I can't really seem to find a straight answer. I will be in Europe this summer and have a DINC2 that I am bringing with. In order to use a foreign (non-Verizon) SIM card I have to unlock my phone. For a DINC 2 stock ROM you can easily go into settings->security->unlock sim and type in the unlock code (which I have already received from Verizon). I have rooted though and am running Cyanogenmod 7. There is no option to unlock SIM in this ROM. I found an answer online that says if you flash a stock rom then you can unlock, I have not been able to find a stock rom for the DINC 2 though (http://forum.xda-developers.com/showthread.php?t=1678250).
So here are my questions:
1) Does anyone have a link to the stock rom?
2) If I flash this ROM and unlock my SIM can I restore Cyangogenmod without losing my unlock?
3) Has anyone used a rooted DINC 2 outside of the US that has been unlocked from Verizon? If so, can I simply wait until I arrive at my destination and pop in the SIM card and type in my code that way?
Any help would be appreciated!
1) Stock based ROM: http://forum.xda-developers.com/showthread.php?t=1219471
OR
Complete RUU: http://www.filefactory.com/file/c25....01.1111_NV_VZW1.92_release_225831_signed.exe
2) I think it'd work but you'll have to try it yourself. Do you have a friend on a GSM carrier?
3) I have no idea but if the unlock is permanent, I think that's what you'd do.
Flashed the stock rom, unlocked the sim, and reflashed cyanogen. Everything seems to have worked great. I guess we'll see in a week if I can connect to a GSM network! Thanks for your help
According to Verizon the SIM unlock is permanent and you will not have to enter the code again. Even after flashing roms, stock restore, etc.
In addition, andyBonestock's ROM and SkyRaider's Zeus v1.3 Sense ROM are based on stock and I can personally confirmed them to be working in a rooted & Sim unlocked DI2. As VZW customer in good standing, you call Global Support & within 5 to 10 minutes, CSR will find the 8 digits unlock code and walk you thru the steps - scroll thru the Settings and input it, press the Enter key and DI2 will reboot after showing it's unlocked (yes, it IS permanent)
For voice & SMS, AT&T and T-Mobile (and, China Mobile HK) Sim cards will work (power down, insert Sim, restart) - broadband/WiFi access will need proper APN settings, and, account will need to be provisioned for data access.
DI2 was in GSM mode, unlocked & worked fine when we're in Bermuda last month.

Thank you so much for your information. Just wondering, are you still able to use global sim? I use MROM and if I reboot my phone after flashing the SIM is back locked again

Yes, affirmatively - Mrs. L has continuously run her red DI2 on SkyRaider Zeus and GSM mode is fine. I was running SR too - it had no problem when we're cruising down in the Caribbean islands - switched off CDMA to avoid roaming & data charges on the ship and on land, used my China Mobile prepaid Sim, great for voice and Int'l SMS - no data roaming as it is NOT provisioned for and tapped WiFi @ local Starbucks - locked onto a 3G AT&T tower in Old San Juan, PR. Every now & then, it might find & stay with a T-Mobile signal, but usually the Sim card settings prefer AT&T over T-Mo.
Currently, I'm running Nit's Stock Sense v5.0.m-ext4 Rom, it's global ready - works just as good - have played with all of the new custom Roms but always finding my way back to 1 of the 3 Roms mentioned here as the default. Have Currents, Google+, Play Magazine, Play Music & SoundHound, OneNote, QuickOffice and Wireless Tether running on mine - and I get to play the latest JB 4.2.2 on the Nexus 7 WiFi tablet, so this is fine for my needs.
Heading toward the end of our 2 year contract, main/primary line will be eligible for upgrade next month but I'm not in a hurry to let go of unlimited 3G data (although my usage has been consistently under 1GB/mo, mostly 500 MB or so. Already trying to re-sign me for another 24 months with an early upgrade Email offer that I must call in for ...

I am planning the same thing: going to Europe next month with a recently rooted phone. Did you just call Verizon and they gave you a code? Did you tell them you were traveling or did you make up some sort of story? Thanks!

Also I am planning on flashing CyanogenMod very soon. I assume you would now recommend that I wait for the code and unlock the SIM before I do that, correct?

Things might've changed a bit at Big Red with the unlocking code, but not by much. First, I would strongly recommend using a near stock global Rom (Andy Bone's - the difference being that it'll stayed unrooted and 99.5% stock basically - Superuser installed.
You need to be a Big Red customer in good standing (bills are paid/current & on account for 3 or 6 months continuously) - and have a non VZW-Vodafone Sim (known working prepaid Sim from AT&T Gophone, T-Mobile, or foreign Sim for test & verification afterward) - phone should be S-off and unlocked, CWM installed if possible (so that you can make a full backup copy of your Stock Rom with APN/PRL (save it to a HDD, USB or Cloud storage)
Call up VZW from another phone line (mobile, home/office, VOIP or whatever - that they can call you back from if necessary - ie. disconnected while on hold) - from among the automated Menu option & voice prompt, select Tech Support for smartphone and/or Global Support - if you get routed somewhere else, ask them to forward to Global Support.
Give them your account info & verify, passcode and/or Soc. Sec. etc. - tell them you need to unlock the DI2 for travel and to be able to use another prepaid Sim card. S/he will read their scripts and inform you that you are responsible for charges, damages and will have no access to support - acknowledge & agree, they will ask confirm your email address & send you the written disclaimers, etc. You might be put on hold for a few minutes, do NOT hang up - make sure they have your immediate call back # - as they will need to go into their database & look up your IMEI's unlock code. Once they have it, they will come back on and walk you steps-by-steps, to go to the Start Menu and submenu, and get to the unlock screen - input the code (I believe it was 8+ digits) - and as soon as the last correct digit is entered, the screen will refresh & say unlocked. Next, exit & close those submenu, turn off & reboot the phone - whatever instructions, just follow it.
With your own "foreign/non-VZW" Sim already installed, you should be able to switch to GSM mode under Wireless & networks / Mobile neworks - and see the new "Carrier's Name" displayed and likely an (E)dge symbol instead of 3G, that is your confirmation of a successful unlock. It is permanent, regardless of switch & flashing to other Rom, etc.
That's it. Copy & flash your choice of Global Roms, unless you are planning to use the DI2 overseas or elsewhere and not using CDMA again ever, I recommend staying with one of the proven ones here - ICS/JB or 4.x ones are cool to play, but battery life is average at best - trust me on this one from personal experience while traveling. Customize & configure the Rom to your own liking - plenty of Google Play (Store) update once it is up & running as many of the preloaded Apps have been revised/updated many times since - best/fastest over a good WiFi connection - then, make both a TB backup of the Apps and a full CWM Recovery backup image - save them both to HDD/USB and Cloud Storage - mission accomplished.
For use within USA, you will have 100% working voice calling & SMS/texting with AT&T and/or T-Mo's GSM network, and 2.5G data only if your plan has data bundled as add-on, and the APN settings are auto-updated/loaded. That's about it - for as little as $30/mo - you can use this device for unlimited calling and texting, and works great when you are on broadband over WiFi. Load an offline Map like Nav free USA with maps (16GB or 32GB mSD is recommended for storage) and you can maintain turn-by-turn navigation on the go.
Any other questions, please feel free to ask and/or leave me a PM - and will try to address them as best as I can on practical usage. For technical help on specific Roms, the developers are your best friends. Good luck, enjoy & have fun.

[Q] M8 DUAL SIM no LTE

Hi,
I have an international (EMEA, model 0P6B640) HTC One M8 Dual Sim which runs on Lollipop, and is unlocked (bought from a shop, no network/carrier). I just moved back to the USA, to find that the 4G-LTE does not work as this phone does not have bands 2, 4, or 17 unlocked. I wish to unlock them so that I can get a T Mobile or ATT sim card.
I know from reading these boards (thanks guys!) that this should be possible as it is a software issue, and that there is a list of things I need to do like root, S-off, super cim, and then flash the appropriate rom. I can follow clear, explicit instructions just fine, but am not very phone-savvy, and have no idea where to find the files I need or exactly how to do these things.
If anyone could help me out with what I need to do and the order to do it in, I would really appreciate it.

SIM Locked T705

Hi! I've been meaning to root and change rom on my Galaxy Tab S 8.4'', it's been painfully slow, even more now that i have a OnePlus 3.
The thing is, it's sim locked to a carrier in my country (Portugal - MEO), i know i can just root it, flash TWRP, really easy.
The question is, can i just change rom? Will it unlock just by that? Will it bootloop forever?
Thanks in advance!
Edit: I know to unlock the sim, i have to do something called "network unlock", but i was just wondering if i can change roms without doing that, i don't care if it stays sim locked, i don't want to change the sim, just the rom.
Edit2: Just to clarify, i don't care if the sim stays locked, i just want to change roms!

When you mention sim unlock code, are you referring to a code to unlock the sim or carrier/network unlock code?
I've never personally come across a situation where a phone re-locked to the original carrier after unlocking with a code or using a free method. This includes flashing ROMs, bootloaders, and modems to an s2, s3, s4, note 2, note 3, and note 4..

The quickest solution may be to buy an unlock code from eBay. Unlocking by code should be permanent.
My phone Samsung GT-N7100 how to convert 4G

Any way to get the OEM unlock to become available?

Hello all,
I just recently bought a Google Pixel XL with model number G-2PW2100-022-B. I've read online that this could be the Verizon version but could also be the unlocked version. Does anyone know for sure which model I have?
Next, I didn't know that inserting a Verizon SIM would lock down bootloaders and such. Is it possible to get the option to become available again, ever? Even with a non-verizon sim card? I also have T-Mobile service and sim card but inserting and activating it on the Pixel didn't open up the OEM unlock option.
I've wiped it numerous times (factory reset) and I cannot flash the factory images, so does anyone know if I have a chance of rooting this phone/unlocking it? Or should I just sell it and try again?
Thanks, Sam
a non public method is available now to unlock your bootloader pm me
