updating to nf9 lose sim unlock? - T-Mobile Samsung Galaxy Note 3

I was wondering if anyone knew if I update the baseband to nf9 will I lose sim unlock? I just want to make sure before I do since I use att on a tmobile note 3. Thanks

Updating to NF9 or any other firmwares, roms, mods, themes
or basebands have nothing to do with sim unlock.
Once your sim is unlocked the only way it will be locked again
would be if you or someone else locks it again.
It has nothing to do with any upgrades....
Good luck!

You will not sim lock.
Tip
I turn mine off when upgrading since you reboot alot. I turn it back on when I done. Same for screen lock.

error post

So, do I understand correctly that once I unlocked my phone with chainfire region lock which supposed to unlock SIM as well, my phone remains unlocked even after firmware update?
How about resetting NV? In other words does anybody know where SIM lock status is stored and what one should try to avoid to not disturb it?

The sim lock is tied to your sim card and you can change that by going settings, security, Sim card. The sim card lock protects your phone from being used unless the pin is entered.
Chain fire's region lock is totally different, it allows your phone to change carriers.
Sorry if I confused you. I was just stating when updating your phone you can turn off the security on your sim card and screen lock, so you don't have to enter them each time you reboot. Once your phone is stable reset the security on your sim card.

I think we're talking different SIM locks, I'm talking about this http://en.wikipedia.org/wiki/SIM_lock , you're talking about SIM card lock menu, but I believe OP mean SIM lock as enforced by service provider to not use another network, otherwise the title of this thread makes no sense.

Help! Entering TMO USA TP2 SIM Unlock code, where do I enter it?

Guys I'm over in Europe and attempting to use a vodaphone SIM, I'm running NRG's ROM and radio 4.49.25.17.
T-Mobile had kindly provided the SIM unlock code for my TP2 prior to my trip but when I put in the Vodaphone SIM it doesn't prompt me for an unlock code?
Do I need to manually enter it somewhere?
I think its supposed to prompt you with a screen asking for the code, make sure the Vodafone sim is properly inserted and if that doesn't work you can try looking up the phones engineering mode.
Is the device booting into Windows Mobile & usable with the other SIM card installed? Where did you buy it? Sounds like it may be unlocked already. Anytime I put the wrong SIM in a locked device, on boot up I would get a message for the unlock code & device was unusable, would not progress past this screen. You had to either enter the unlock code or reset & remove the SIM card.
First, check if your device is unlocked by going to Start>Settings>System>Device Info and on one of the tabs, it should say unlocked somewhere. Or, you can check it by downloading ATCommander onto your device and entering [email protected]?40 into ATCommander. It should return 0 if you're unlocked. If it returns 1, you're SIM locked.
Now, if you are still locked, try flashing the Stock Tmobile USA ROM, and insert the Vodafone SIM then. Hopefully, a dialog should come up with an area to enter you unlock code. On the Kaiser, you supposedly had to be running the stock AT&T ROM in order to get the dialog unlock the device with an unlock code. Hopefully that will work. If not, TMobile tech support could probably answer this. Hope that helps

[Q] confirm if phone is carrier unlocked

I just received my nitro and I'd like to know if it is carrier unlocked. I popped in my orange sim card and booted up the phone. I wasn't asked to enter a code however. I'm still in the states, should I confirm with a tmobile sim card or is it safe to say my phone is unlocked? Thanks.
If it has accepted non at&t sim then it is unlocked obviously

do you have a custom rom? if so it may not ask for code, so it may still be locked. Try t-mobile sim just in case.
Thanks to the both of you for your replies. I was on a fully stock lg nitro. It turns out I was inserting my orange sim card the wrong way therefore the sim lock notification never came up. I popped in my sim card correctly, and sure enough it was blocked. I entered my code and everything went perfectly. I'm now on CM9!! Again thanks for the help

SIM network unlock PIN

I installed cm 9 to my arc and it is usable without sim. But when I insert the sim, it wants a SIM network unlock PIN. What's that? It isn't the sim lock code because I entered the sim lock pin after the phone lock and before my lock pattern.

Just press dismiss and ignore it. It's some CM thing in the ROM.
Do I need to dismiss it every time I reboot? Its okay but its better with a solution.

Yes, because there is no solution right now for it.
The sim unlock code is provided in the box that u bought the sim from. if its a pay as you go pack try to find the sim unlock code if its pay monthly is really hard to find the code, i think they might need to get u a new sim card.

No SIM card

Hello I have an unlocked SGH-T989D phone but the problem is it will only detect sim cards from Koodo even though it is unlocked, I've tried flashing many different roms and different radios but nothing is working. Currently on stock 4.0.4 /T 989UVLE1, yes the phone is unlocked I checked multiple times. Anyone know how to fix this?

How do you check if a phone is unlocked if any SIM you try from another company is not read by the phone?
I think you need to try the unlocking procedure again, I don't think it was properly unlocked

What method did you use to unlock it?
I did it with this (http://forum.xda-developers.com/showthread.php?t=2024514) and not a single time was I asked to check with the code that you have showed me
This IS for the T989 though, not sure if you can use it for the T989D or if it's different in a way.
Sorry that I can't help, I hope you get the answers you are looking for

My brother used that method a long time ago and he was able to use different carriers, but now nothing works but Koodo, and I never get asked for an unlock code, just says 'No SIM card'

Yeah, this phone will not ask you for an unlock code, if you follow the procedure correctly it will read any other SIM card on it's own
Try unlocking again with what you have, the stock 4.0.4 and UVLE1 combination, it should be the right one. Do the procedure again until it reads the SIM card you want.
Another possible problem could be that your SIM is damaged or not well placed. It happens to me when I try to fit a Micro SIM on it, if it is not well placed it will not detect it. Try using other SIMs or try it on other phones to see if your SIM is the problem

I tried unlocking it again, doesn't work, tried different sims, and still doesn't work, but those other sims work on different devices. Only the Koodo one works on mine, which was what it was locked to before unlocking.

Well in that case I'm all out of ideas.
One final question, when you insert a SIM on your T989D that is NOT Koodo, do you get an "Invalid SIM", "No SIM" or just an empty signal bar?

It says "No SIM card.|Emergency calls only"

My conclusion is that it's having a hard time reading the SIM card. When you put another companies SIM card in to a LOCKED phone, it will show as invalid SIM (sometimes it even shows signal but is unusable). Since it says "No SIM card", I believe it's more of a hardware problem than a software one.
All I can think of is try moving the SIM card around, turn on. If nothing changes turn it off and move a little again, the turn on and repeat until it reads it.
Apart from that, I have no clue what could be wrong with the phone.
Turn on your phone without any SIM. If you get the same message (No SIM card.|Emergency calls only|) then it is most definitely your phone not reading your SIM correctly. If you get Koodo signal WITHOUT any SIM inserted (which I doubt but it CAN happen) then that means you have a faulty SIM Card Reader on your phone.

It works on Koodo but only if the sim is inserted, also I tried moving the sim around and it still isn't reading. I think this is a software issue.

Sorry man, I'm all out of ideas. I mean I've experienced the problem with the "No Service" thing, but I basically fix it by switching to 2G since I know there are some areas that I can't get 3G coverage. As for your problem, it's basically not reading your SIM entirely (by either software or hardware issues) and I wouldn't know how to get around that.
Best of luck to you

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!
