Cant find OEM unlock? - Samsung Galaxy A71 Questions & Answers

I have enabled developer settings set the date forward and also tried looking with the sim card in while connected to computer via usb. my model is SM-715W and I used a sim card from telus.

I'm on the same boat, does your set works on 2g and 3g?

Now don't quote me on this because I am not 100% sure even though I am fairly certain of it.
The USA/CA version of a71 cannot unlock bootloader.
Again don't quote me on this, I do not have confirmation only what I've heard so far.

Weird SIM unlock question

Hi,
I just unlocked my SIM card via a Verizon supplied code. I found an old AT&T SIM in my desk drawer - I called AT&T and confirmed the SIM is not active (nor has it ever been activated). I inserted it and the phone came up. However, if I use APN Manager, it shows I'm connected to Verizon. I'm able to make and receive calls.
I thought by inserting a different SIM I would be using that providers network instead of Verizons? Or do I need to manually change that somehow?
It's important I figure this out before my trip next month to Panama.
i think in usa the other network gsm bands are locked (so u wont be able to get service it wil just show no services i think) so even u insert them u wont be able to use that network ...
and u can change ur settings to gsm from mobile in network n settings i think..when u leave to panama or out of usa
hope it helps thnx

SIM Unlock Code Screen Missing

Hi All,
I apologize in advance if that has been posted and responded to, but my searches have been unfruitful. My boss has the Motorola Droid 3, stock rom, NOT rooted on the Verizon network (in NYC). He will be traveling abroad to the mid-east and contacted VZW Global Services and they provided him with the SIM Unlock code.
I then proceeded to insert my AT&T SIM card into his phone and booted it up - in anticipation of the SIM Unlock Code screen so that when he gets to his destination country, all he'll have to do is insert the SIM card which he will purchase there.
Unfortunately, no such screen appeared. I was able to access the phone's other functions and was even able to go into Settings>Wireless Settings and switched the device to GSM/UMTS only (from the default 'Global' setting). Still, nothing occurred. I then forced it to search for a network (even though automatically connect was checked) and believe it or not, midway through its search, the phone completely rebooted on its own. I thought that maybe NOW, when the phone finishes loading, that it will ask me for the SIM Unlock Code. Well, it didn't. The phone just booted up normally and indicated that there was no service (bars with the red circle and slash through it).
We called Global Services back and they claimed that we will not see a SIM Unlock code for any US-Domestic carrier SIM cards (sounds fishy to me) and the SIM Unlock Code screen will appear ONLY when a Foreign/Non-US Carrier SIM Card is placed in the phone. My suspicion is that the Global Services rep doesn't know the difference b/t his a** and his elbow and was just saying anything that seemed plausible to get me off the phone. It would be VERY BAD if my boss travels to his destination and operates on the assumption that this will work once he inserts a foreign SIM card and for it not to work at all.
Any thoughts/insights into this would be VERY much appreciated and if this topic was already discussed on another thread, I would very much appreciate the link to that thread.
I have seen similar topics on other phone model threads, but none of the instructions in each of those respective threads had a solution that seemed applicable to this specific problem.
Many MANY thanks in advance!

You should most certainly see an unlock screen with a US based sim card. I used an old deactivated T-Mobile Sim card to get my unlock code prompt. try going to the phone dialer and enter *#*#4636#*#* - give it a sec and a menu will come up. In the menu scroll down a bit and you'll see a network selection bar. Tap the bar and select GSM Auto (PRL). You should immediately get a popup or perhapse after you back out of it. If not, scan for networks again. If it still gives you problems - PM me and we'll get it figured out.
network SIM unlock screen missing for T-Mobile US
Folks,
I am experiencing a similar issue as the original poster. No matter what I do, I can not get the Droid global (stock rom, v2.3.3) to attach to the T-Mobile network. If I follow the instructions"
*#*#4636#*#* - give it a sec and a menu will come up. In the menu scroll down a bit and you'll see a network selection bar. Tap the bar and select GSM Auto (PRL) ".
I see the screen momentarily flash the t-mobile network, then switch back to indicating that the network type is CMDA-1xrtt. Any guidance would be greatly appreciated.
BTW this sim works fine in a BB Bold 9000. Also it is just a simple voice/messaging sim - no data plan.
Never mind - after more research, seems I have a phone with the US carriers locked out. - off to see if I can update it

I was to access the screen you mentioned however I was unable to get it to ask for my unlock code, any ideas?
I had the same issue. The unlock code was already put in. Though this may be, there is more you need to do to have it working on US carriers like AT&T.
The guide is here

I c, U have to use Non-US SIM CARD. otherwise U have to unlock the US radio first. but if U having trouble to pop the SIM Network Unlock Code screen, just put non-US SIM and set the mobile network from global to gsm/umts. these also apply to those whose troubled with subsidy lock, so they can input the code.
Worked for me with tmobile or att sim card in the phone. You have to backup rename the build.prop file in the system(Rename the old build.prop to build.bak) put the new build.prob file in the system, restart the phone and wa-la, it will ask you for an unlock code. Enter it give it 15 or so sec reboot the phone, select GSM/UMTS and wait 30sec to 2mins you will receive a signal.

No T-Mobile network

I took my girlfriends S1 on holiday with my 3 network sim in it, when we came home I put her T-mobile sim back in, now it will not connect to the T-Mob network, it will connect to 3G? Putting the sim in my SNote and all is well. I have since install a custom rom to see if that would help but still no good.
Galaxt S1 running CyanogenMod 10 nightlies.

Believe me I have taken the sim out and tried it in the "wrong way" lots of times. I have also looked at your solutions page before, very helpfull. But why will the sim work on one network but not on another, and the non working sim will work in another phone????

Check the modem on both phones.
If the phone that doesn't recognize T-mobile has a different modem, then load the modem that the phone that works has through oden or CWR.
Hope you know how to check the modem and load new ones.
Good luck

This will happen as T.Mobile may be using a different Radio band ..most likely you changed the APN and Network settings when you used it with another SIM Card , whilst abroad ...all you may had to do was check your Network Settings in menu> settings>wireless and Networks> Mobile Networks and reset it back for the T.Mobile network, initially
To understand this better read this http://en.wikipedia.org/wiki/UMTS_frequency_bands
at the same time since you upgraded by flashing to JB, you may have to select a new modem that is suitable for JB, you will find all modems at My Android Collections
Data but no calls
Me back again, I have tried all xx modems, reverted back to stock rom, then GB, them back to CM10. When I first turn on phone it finds network (i'm on a giffgaff sim now) it says GiffGaff at the bottom of the screen for about 2 seconds, then it says emergengy calls only. I can still connect to internet. APN settings correct, IMEI correct, In Settings - About Phone - Status, i'm connected to network, service status = out of service, mobile network state = connected, my phone number = unkown. Where can I go from here?
More
Another thing I have just noticed, when I take the sim OUTwhen the phone is still ON, the "no network" on the screen turns to giffgaff,

Try to set your phone number by following this guide , it was written for a Korean version, so just adjust it for your phone version.

No Unlock Menu Pops Up

I bought a US Cellular Moto X off of Ebay. I unlocked the Moto X successfully since I receive the message each time I turn on my phone but no unlock menu popped open.
I have the correct T-Mobile SIM card, I am able to search the internet but I can't make calls, receive calls, and the same for texts. When I call, I receive the welcome to verizon wireless message and the texts do not go through.
Please help.

If you go to the main settings menu, then under Wireless & Networks, select More... and in the new screen that pops up, select Mobile networks, then Access Point Names, you'll have to find the APN settings for your carrier and add them manually if they don't show up when your SIM is inserted.

There is a way to access the APN list using a hidden programming menu. I don't know if the dialer shortcut will work on the version you have, but to try it, dial ##7764726 if it works and asks for a password, use 000000
One of the options should be APN controls. Hopefully T-Mobile US will be one of the APNs.
Is it possible that there might be a problem with your SIM card since some features work and others dont?

I'll try that.
It's US Cellular phone but I use T-Mobile SIM card, it was a brand new sim card. When I dailed, I kept getting "Welcome to Verizon Wireless"
Thanks, I'll let you know how it goes in a few hours.
According to US Cellular's webs site, their device supports CDMA/EVDO, since you are trying to use it on T-Mobile, you'll need to manually switch the phone to GSM/UMTS mode, or Global Mode. (App drawer -> Settings icon -> (under Wireless & Networks) More... -> Mobile Networks -> Network Mode).
While in there under Mobile Networks, you'll also need to tap on Access Point Names... If the APN settings came down automaticlly from T-Mobile you need to select it. If no entry for T-Mobile exists, you'll need to find the settings and create one. (Google found them when I looked) NOTE: with Android JB 4.2.2 on my Verizon X (XT1060, also supports CDMA/EVDO in addition to LTE and GSM), the APN settings came down automatically. After upgrading to KitKat 4.4, I had to manually enter them.
When I setup my Verizon X for use with my T-Mobile SIM, I couldn't get MMS working for some reason, even though I was using the same APN settings as my T-Mobile Galaxy S3.
Also, keep in mind that T-Mobile uses 1700/2100 AWS for their HSPA+. As far as I know, only the T-Mobile version and GSM Developer edition supports this band, so you might not get "4G HSPA/HSPA+" with your X even after setting it up correctly. If you are lucky, and are in one of the areas where T-Mobile has completed re-farming their spectrum, you will get H+.
Good luck.

Based on that screen shot, your preferred network mode is still set to LTE/CDMA... that is wrong for T-Mobile. (SEE POST #12 of this thread!!) You want it to be GSM/UMTS or GLOBAL!! And you want to have the boxes checked for Data Enabled and Data Roaming.
You do not have options for Global Data Roaming Access and Access Point Names which I have on my Verizon Moto X, so that makes me question a few things....
In the first post you say you successfully unlocked your phone.. do you mean SIM Unlocked, or BootLoader Unlocked??
Also in the first post you mention seeing a message each time you reboot.. What exactly does the message say?
I ask because if you unlocked the boot loader, your phone could still be SIM locked and therefore not recognizing the T-Mobile SIM properly, and not giving you the Global options and APN options needed for GSM mode.

Yes, if not SIM unlocked, you're stuck. You need to get it SIM UNLOCKED.
Take a look at this thread -> http://forum.xda-developers.com/showthread.php?t=2422854 apparently some are using cellunlocker [.net] to get their X SIM unlocked, although they don't have US Cellular listed when I picked MOTO X from their list, so you might have to pick "Unknown" or "not listed" for the carrier.

Sprint Note 8 activated whit boost mobile but!!

I activated my sprint note 8 whit boost mobile 2 days ago. Everything works perfect, exept Lte plus. If someone have the same issue and solve it. Please help me out whit it.
How did you activate a sprint note 8 with boost mobile? I tried and all they would tell me was that it was not able to be activated with their network.
Sprint tells me that the phone is unlocked domestically and globally. But boost says that the phone is not able to be on their network because sprint will not permit their note 8's on their sister network. I have model n950u. And the boost rep essentially said that people would leave sprint for boost mobile in search of a better deal if the note 8 was available.
Again I ask, how did you do this?
Edit: the only real difference I see in your phone and mine is that mine is still on April's update and yours is on May's. Hmm.
The phone does not come unlocked. There is also no way to enter a pin to sim unlock the sprint note 8. It actually has to have software flashed woth odin and a tool called samunlock
If you search on ebay there is a guy who does it
For very cheap
He has to remotely connect to your computer while your phone is connect to the computer by usb. Did sprint unlock the phone for you by sending a software update specifically to unlock it? If its truly unlocked . Open settings software update. At the bottom it will say
UICC Unlock
Your device is unlocked for any sim card.
If that is the case i dont see why you would not be able to activate it on boost. They use sprints network. When i unlocked mine i can put a tmobile sim card in it and i dont have to set the apn or anything. The way i had mine unlocked its setup with all apns. So i just put in the sim card and it connects to that network automatically. I dont see why this would not work for boost. If it is domestically unlocked put a boost sim in it open the phone dialer and type ##brand# that may work
