how to check if captivate is unlocked - Captivate General

Go to the dial pad and enter

If you are not unlocked check this thread http://forum.xda-developers.com/showthread.php?t=906255 it worked for me.

And you will also have to change your apn settings to your network for mms and data to work properly

If you put in a SIM card from Bermuda and it didn't prompt you for the unlock code, it is unlocked. It shows AT&T because that is the network it is currently connected to. I assume you are in the US right now?
If you put a SIM card in a phone that is locked to a different carrier, it will not connect at all, but will ask you for the unlock code.

thanks! yeah i'm in america at the moment.. it's unlocked which is awesome because i didnt buy an unlocked version. yeah. the apn settings, i am going to work on them now. love this phone so far.

So, can someone explain to me how the GSM world works with phone swapping?

Literally all I have to do is insert my SIM card in a new phone, and I can use it like normal?

So how do you know if it is unlocked? Is that like a clean ESN for CDMA phones? If you buy a phone on contract, is it automatically locked until the contract is up?

If you are buying a phone that is sold by a USA Carrier its got about a 95% is LOCKED. You will know when you put the sim in, if you get ERROR SIM LOCKED, Please Enter Unlock Code, it's locked. Otherwise if it lets you into the phone your golden. Locked/Unlocked is not even close to ESN being clear/bad. Just means carriers have the phone locked to them, you can buy an unlock code for almost any GSM phone for $20 or less
So the lock is just specific to a carrier and not a user?

Correct. So that you have to come to them to get that specific phone
Some phones can be unlocked via tools you can find here on XDA other phones require some bigger equipment and you typically have to go on ebay or a similar site to get your unlock code based on your IMEI number

Network unlocking

My Sprint variant arrives tomorrow and I'll need to network unlock it to use with my carrier (wanted the unlocked bootloader).
Am I going to have to go on say eBay and do the IMEI method or will the first sim inserted feature work?
If the IMEI way, are there 3rd parties currently that support the S7?
note: I don't know how generating the code works so I don't know if it's model dependent when generating it.
EDIT: Can confirm first sim inserted does not work. Prompted with "Invalid SIM card" with an AT&T sim in Sprint variant.
I can tell you, as far as I know no one has tried the 1st Sim inserted locks to that network theory...I hope you give it a shot, as it could confirm or deny this theory.
Sprint has unlocked bootloaders?
Good questions btw, I'd like answers to these questions as well

I was surprised too. I asked a rep before purchasing and they said they did; as well as a couple others stating it. But rather that's true or not, I'll find out soon enough
I can confirm that the AT&T s7 was sim unlocked. Bought outright at Bestbuy and picked up tonight, I put my cricket sim in and it worked perfectly. I can not verify if it is locked to cricket or not since I don't have another carrier sim to try. I received no notifications that I had a cricket sim or anything it just worked.

Cricket works on all? AT&T phones because Cricket uses the AT&T network. I have an AT&T S5 using cricket with no changes needed but APN settings. I'll confirm tomorrow, unless someone else does before hand, if the first sim feature works with a Sprint variant.
Unless I'm mistaken even on AT&T phones you still had to unlock then to us a cricket Sim

I didn't with my S5, unless something changed.
The OEM unlock option is in the developer options of the att s7. I only have an att sim though, so i can't test it. I didn't buy mine outright.
Cricket Sims work on AT&T SIM locked phones.

Same for T-Mobile. There is also a "Device Unlock" app in the T-Mobile folder/
I will try a different sim today...
My phone arrives later this week - no next day shipping for me I guess I will try my Vodafone SIM first when it arrives and see what happens.
Will post the results if no one beats me to it.
FYI... The OEM unlock option in developer options has absolutely nothing to do with Sim unlock.

it begins the process of allowing you to unlock your bootloader, if your bootloader is unlockable.
Ah ha

Since you bought the phone outright, can you still get on the GearVR promotion bandwagon?
I am on the ATT Prepaid (GoPhone) plan and don't want to change over to post-paid. But I was told I can't actually pre-order and still retain my plans with GoPhone.
Hey TehPirate_,
Unfortunately the Sprint S7 and S7 edge can't be unlocked by code
you can however contact sprint to request the to unlock it
The other GSM networks can all be unlocked by code such as AT&T, MetroPCS, T-Mobile(by Unlock app confirmed unlocked today Rogers, Fido, Telus, Bell, Vodafone, etc

Took me half a day of phone calls and emails but managed to get sprint to unlock it for me.

Please Help. How do I activate, and unlocked tmobile Galaxy S8+ on Verizon.

So I just received my unlocked galaxy s8+ G955U from swappa. I was hoping it would be as easy as putting in my previous nano sim card from my Nexus 6p and activating. It isn't. The branding is t-mobile. Showing t-mobile screen when I turn it on. I tried activating from myverizon , but when I enter the imei it says: "The phone associated with the Device ID you entered is not compatible with the Verizon Wireless network. Try a Different Device"
I purchased an unlocked phone hoping to avoid most if not all of the verizon bloatware. But, I need to be able to make phone calls and tie it to my Verizon account.
Any help, or suggestions would be greatly appreciated.

clearly you got the Tmobile s8+ model. Even if its unlocked it only works with Gsm networks. Verizon is CDMA not gsm. Return for a refund and buy a no-career unlocked phone. Good luck
This is the model you need https://www.bestbuy.com/site/samsung-galaxy-s8-64gb-unlocked-midnight-black/5803742.p?skuId=5803742
I think you're right. This sucks. But, it's good to know. I've been on the phone with customer service for 40 minutes trying to get it activated and still no luck.

What I don't understand is that the customer service representative says it's activated on her end. I just can't make or receive calls. No lte or 3g shown.

That is 100% absolutely false and incorrect. All the US S8+ models have the SAME EXACT hardware. Only the firmware is different.

OP, are you SURE it's network Unlocked? The T-Mo branded S8 shipped network locked. If it's network Unlocked, it WILL work on Verizon, but it will still have the T-Mo bootup screen and apps. That's the firmware.
If you want no bloatware, check out the threads for flashing the Unlocked Firmware.
After exhausting all my options I took my friends advice, and called t-mobile. Turns out the phone is still locked. So it's either the seller unlocks it, or refund.

Maybe you can answer this question. If the phone is still locked. Can I flash firmware to unlock it, and activate it on Verizon. (I don't even care about bloatware anymore. I just want to have a working phone)

No, you can't unlock it just by flashing the unlocked firmware. T-Mobile will have to unlock it.
Read one of the threads a out flashing unlocked firmware, it will answer many of your questions, including the ones you have asked in this thread.

OEM Unlocking grayed out

Purchased from Google unlocked.
Running .30 version.
When I initially received the device I pulled the SIM from my OG pixel 1 and inserted and booted the 3. Set it up (running on AT&T) and used it. This morning I decided to root for theming only to notice it was grayed out. First thought was to factory reset and reboot with no SIM inserted. Did that. Still gray.
Am I missing something new?

Are you sure you received the google version phone and not the Verizon one? Did you notice if it was grayed out before you inserted your sim?

Wouldn't the fact that it takes my AT&T SIM mean it is the unlocked variant?
To answer though... I did not notice.
UPDATE: Called Google. The tier 1 guy said, "Per our engineering documentation this option is designated as disabled on the pixel 3 line."
I have requested an RMA even though I hope he was wrong and that someone can enlighten me before I send it back.

Sim unlocked yes. But not bootloader unlockable. I'm guessing you have the Verizon variant.

When my RMA is completed how will I specify that I don't want the Verizon variant?
As I'm sure you already know the store offers only three options and I verified that I chose the 'unlocked' option. Anything I can do to get what I need should I decide to reorder?
Also the store says the verizon variant comes with a SIM card which was not included in my packaging.
I'm really steamed at the moment... I do thank you for replying.

Again my friend, I'm just guessing. It could also be possible that from what I've read, the P3's were initially sim locked to Verizon only, even if you ordered the google version. It could be possible that when you installed your at&t sim, it locked the bootloader. Again, I'm just guessing.

Sure... I get that. I have been approved for an advanced RMA. Wasn't trying to seem harsh. The rep that gave me the advanced RMA did say that it SHOULD allow toggle. I'll be sure to attempt bootloader adjustments before inserting a SIM this round.
I don't think the Google version was sim locked to Verizon. That doesn't make sense at all. The device needs to connect to the internet in order for the switch to become active from what I understand. So if you don't put a sim in then you will need to connect to wifi. Something is amiss or we're not getting the full picture. Why would a Google bought Pixel anything not allow bootloader unlock? Even if you put in a Verizon sim it should still be active.

My thoughts exactly. The grayed out switch does say 'connect to the internet or contact your carrier' below the toggle. All while there's an LTE signal indicator on the status bar. I'm perplexed, truly. This isn't my first Android rodeo and I've never encountered this before.
I bought mine through Project Fi. I tried to unlock the boot loader first thing but the OEM unlock was greyed out. I had to activate the phone on the Project Fi Network before OEM unlock became available (I used the eSim). I wonder if they've linked the OEM unlocking switch to the network activation somehow. Has anyone bought a Network unlocked Pixel 3 from the Google Store, stuck a Verizon simcard in it, and then tried to unlock the bootloader?

I unlocked mine with a Verizon Sim in it. No problems at all. I also did the same with 3 different pixel 2's when the pixel 2 was first released. Again, not one problem with any of them. I see a lot of talk about the unlock possibly being tied to the SIM. It isn't. I know first hand.
I bought my 3xl carrier unlocked from Google. I inserted a vzw sim and activated my phone. After all that I tried to oem unlock and it is greyed out. My phone is running build PD1A.180720.31 and as far as I know it is the vzw build. Tried factory reset several times and still greyed out. Also tried sideloading .30 but it didn't work. Any help would be appreciated.
i bought the unlocked pixel 3 from google on launch, i was able to unlock the bootloader and flash images with no issue. I didnt have my verizon sim in it tho
.31 is the verizon variant.
.30 should be the unlocked variant.
I'm on the phone now... For a third time trying to get an RMA issued. Google support is horrific.
Issued me 2 RMA requests that had a link that was already used.
I was on the phone with them this afternoon and they are sending me a new phone. Hopefully it will be the .30

Interesting. On a side note 2 vzw apps showed up randomly in my app drawer. I was able to uninstall them but they weren't there before. One was messenger and the other I think was My Verizon.

Those got installed when you inserted the VZ SIM.
For those of you getting RMAs best of luck. Their RMA department is a mess, they are not shipping anything. Some of us have RMAs open since day one. There is thread here on it, and a pretty big one on Reddit.

need help tmobile device unlock app not working

Ok so I'm in tmobile prepaid.
I have a galaxy s10e that is was purchased full price from someone else. We verified everything at a tmobile store. The unlock was approved and i got the email approval. The tmobile device unlock app for this phone doesn't work. So I have to go to settings>network>more>network unlock
Or something like that. I get an error message that ends in 0x86
On both temp and perm unlock
I already went through it with tech support 17 diff calls. Nothing. Nobody knows what this error is. Ine tech guy gave me two sets of numbers. Both 8 digits. I believe these are the nck or unlock codes but my question or rather what I need help in is inputting these codes. I tried the generic ones I found online to no avail. The dial codes is what I'm talking about. Also when I reset with unlocked rom it still says to put tmobile sim. And doesn't give me a option to input unlock code that I have
I even called Samsung and they cant help me bc it's a tmobile phone. Tmobile doesn't know how to input the code when I do mention it. And yes I reset the phone put a diff sim. Tried with Abd w/o wifi. Everything.
So now I flashed the U1 rom on it amd the unlock options in the network settings is no longer there. Obviously bc u flashed the unlocked rom on it.
Any suggestions? Tmobile is giving me minimal help bc I'm a prepaid customer
