I'm using the Tmobile dash, How can I know whether the mobile unlocked or not?

Is any little software to detect it?
For me the payment for unlocked this device is expensive. So before the unlocked, I want to confirm that the device is Really locked by the service provider.
Thanks,
Any one can provide suggestions?

Put in a sim from a different operator. If you don't have one borrow a friends. If it works and doesn't mention sim locked when it starts up then its unlocked.

Then I think my mobile has already unlocked.
This device is given by my mother. And my mother has already let the service provider to unlocked the machine. (in US)
and after that, my mother send this device to me. And now i'm using the mobile smoothly in China. *surely using the china-mobile's SIM card*
So for your opinions, I think this mobile i needn't to pay money for unlocking again.
^-^~

anyone knows hot to check it?

----------

about 'unlock' there are 3 concepts here in the forum
1, SIM-unlock, this could be checked via above methods, says, putting a different SIM card to see if the mobile function could be used, if yes, then it's unlocked.
2, CID-unlock, this could be checked via some software (i.e. mtty) , in general, most of the first-hand sold mobiles are NOT cid-unlocked.
Currently there are no free applications for above unlocking. u will need to pay in imei-check website to get ur mobile unlocked.
3, Application-unlocked. this could be done with a free application unlocker.

can this be used to see if your unit is cid unlocked or is it only for finding out if the phone is sim unlocked?

This app declared my device to be unlocked, but it is not. Perhaps it tested App or CID, not SIM.

Possible Code Genereator
I'm not sure how the unlock codes are generated or if they are just random, but my question is If someone who is good at algorithms looks at some of the IMEI and the associated unlock codes could there be a program written that basically generates Unlock codes by using that algorithm?

[Q] Unlock code after each wipe

Hello,
I have a locked galaxy nexus and I enterded the unlock code to use it with another network. The problem is after each wipe (reinstall of rom), the phones asks for the unlock code again.
Is it normal. Is there a way to unlock the phone without having to unlock it after each wipe?
Thanks for your help.

It's not normal in the sense that every other phone remembers it's been unlocked, but it's normal in the sense that mine (and probably everyone else's GN) does the same.

ok thanks but if there is a way to avoid this, I'll be happy
(just for info, where are you from)

My desire used to do this as well.

I'm from spain and I got my nexus from vodafone.

do you mean the net lock? I pay money for unlock it

yes I talk about the code I bought on the net.
So there isn t any way to make this code permanent?

Maybe it's a good thing because you loose the warranty by unlocking.

as the unlock code has been provided by my network operator, no, I don't loose waranty. I am talking about simlock, not bootloader lock.

Mine was not provided by the network operator...

I never experienced this on my HTC HD2 but My Galaxy Nexus does it as well but not every time. It definitely does it every time I change the radio. I have stuck the code on the inside of the back cover.
I have a GSM model that I got from O2 on contract and the sim unlock code was provided by them.

Where did you buy the Code (www.???

GN SIM Network unlock PIN

Hi! I just got my GN and after I boot it asks to enter the SIM Network unlock PIN. This means that its network locked right ? In the box there where nothing related to any carrier so is there a way to find a way to which carrier it is locked to ? And how can I unlock it?
Thanks (Im running AOKP)

I got an app from market recently to unlock my SGS2, maybe try searching the market? That's a bit vague but the app I used on my SGS2 was perfect, generated a code for me and then unlocked the sime when I typed the code in.

Im trying the GSII Sim Unlock app though I doubt it will work.... I was thinking about purchasing an unlock code however I have no idea to what carrier it is locked to. Is there any way I can know this?

Yeah

That's what I used. I don't think the carrier matters, it's all about the phones IMEI number, the app checks that and then issues an unlock code based on that. You don't need to worry about carrier.
Let me know if that app works on the Nexus. By the way, in Ireland you can ring your carrier and request an unlock code. I don't know if that is the same where you are. You could chance your arm and see.

is your nexus cdma or gsm? A gsm nexus wont ask to unlock the sim since they are factory sim unlocked..

Mine asks for an unlock code if I don't use the sim that came with the phone or a sim that is from another carrier.
Do you have a source for where you read that they are sim unlocked ??? Would be interested in reading it.

this reads more like it's a Sim-pin... a pin number associated with the sim card you are using, NOT a pin associated with the phone.

NO! The code is related to the IMEI number of the phone. When I unlocked my SGS2 using that app, it specifically searched for my IMEI number and then generated the unlock code. Nothing to do with the sim.

Its a GSM phone and Im assuming that it is unlocked as it had no logos on the box so I have no idea what carrier it is locked to. Also, ever site that sells unlock codes request the carrier so what can I do ?
Tha SGSII app did not work

Nasty! Can you contact the guys who offer the paid unlock codes and ask them a way around that?

Well, I would contact the seller of the phone, there isn't a locked version of the GSM Galaxy Nexus available, afaik.

Well, you didn't buy a carrier branded one, did you?
I spoke too soon, it looks like Vodafone Portugal sells it Sim-locked, everywhere else it's unlocked. If you bought it unsubsidized, it should be unlocked. Unless you got scammed, and bought it second hand from someone that somehow had bought a locked one.
Where exactly did you purchase the phone?
http://en.wikipedia.org/wiki/Galaxy_nexus#Availability

Bought it off eBay from an Australian seller.... in fastboot mode Carrier Info is set to None.... does this mean that it is unlocked ???

Got reply from seller and apparently there was a code on the box that I had to enter.... my fault :/ Know its working perfectly
Thanks for the help anyways guys

Thanks for the info! I get all my phones for free off a guy who works in a company here so mine was not branded at all but I was sure I had an issue when I put in an 02 sim recently, could have been my SGS2 but will check it out again and see. Thanks for the link.

Galaxy Nexus Successful Unlock (Bought Code)

Hello!
I have an NTT Docomo branded Galaxy Nexus.
Wanted to use a roaming sim so I needed to unlock it.
Checked some sites and finally decided to use the service from this site:
http://samsungimeiunlock.com/
I payed around $32 for the code(depends on which carrier your handset is locked to).
I would have happily donated it to a team who can sim-unlock our phones but I did not have the time to wait since I badly needed to use my roaming sim.
I received the codes in around 8 hrs.
First time using the code worked without problems.
I am not in any way connected to the site I mentioned above.
I just want to help those who are doubting online sites that provide unlock codes.
I guarantee the one I listed above works, and again, I am not in any way connected to the site.
Hope this helps and clears some doubts.
Peace yah all and enjoy your GNs!
P.S. - I unlocked the bootloader, rooted and flashed stock Google ICS 4.0.2 (not Docomo image) prior to inputting the code. Not sure if it would matter though.

If you had unlocked your bootloader then flashed a custom ROM then their would be no need to buy an unlock code would their

unlocked bootloader is not the same as sim-unlocked/sim-free

You should Google 2 things and read.
1. "Unlock bootloader"
2. "Unlock sim"

I'm curious about one thing. Obviously I don't expect you to send me a copy of your unlock code, since I have a CDMA version and it won't do me any good. I'm just curious about the actual process of using it. Do you just punch in a bunch of numbers into the dialer, or what? Like what is the actual process to do this?

Turn off phone, insert foreign SIM, turn on phone, phone will ask for unlock code. 99% of GSM phones are like this.

as nxt mentioned, just insert a SIM that isn't from the network your handset is locked to.
it will ask for the unlock code after booting up.

sim-unlocking doesn't change any of your phone's capabilites. it just lets you use other sim cards, including your original one

[Q] sim network unlock pin on galaxy nexus

Hello

I'm thinking the reason your thread got 100+ views and not one reply is your question being the noobiest of noobs!
Anyway, the Galaxy Nexus isn't sim-locked. the "sim network unlock pin" message you're getting must be a security PIN in your sim.

Maybe not: I've a Vodafone GN and it is network unlocked with a internet purchased PIN code.
Each time I "touch" the rom, the device ask again for that unlock code.

pin code
Witch provider do U have? is your sim protected by unlock code?call your provider and ask for "PUK" code this should help.

Mine was O2 sim locked and I bought an unlock code from an ebay seller. Several weeks later it decided to sim lock itself again without provocation.
Unfortunately I had deleted the email with the unlock code so had to buy it again... Annoying.

This is an ignorant response. The OP's phone is SIM-locked.
OP, flashing a new firmware does indeed SIM relock the phone. SIM relocks can also seemingly appear randomly or after removing your current SIM card from the phone.
This is why it's important to either memorise your SIM unlock code or keep it at hand. Just re-enter your unlock code and you'll be fine.

The OP's question is certainly not a NOOB question.
This is a common problem with what apparently seems codes purchased. When you install a new ROM or make certain changes, it asks for the code to be re-entered. Nobody seems to have a solution for this yet! Upon re-entering the code, the phone will work fine.

I have this problem, but what code i need to re-entering? PIN,PUK...?

Sounds like you need to purchase a sim unlock code from an internet retailer if the code was not included with your original purchase.

If you goto fastboot (volumeup + volume down + power), what does it say in the lines of "baseband version" and "carrier info"?

aren't all galaxy nexus factory unlocked? so it should work with any network right out of box.

Unlocked phone showing same problem
Hi everyone,
Sorry to piggy back on this thread, but I thought this might be helpful.
I bought an unlocked phone (NEVER locked to any carrier) which was working fine for 3 days. Suddenly this morning, it asks for the "SIM network unlock PIN".
I have not modified the device in any way, it is original with locked bootloader, not rooted, etc.
The SIM had not been removed in the time period, and the device had not been turned off. I had it on airplane mode overnight, then it showed the problem in the morning.
Its not a simple SIM pin code, it asks me for that when I boot the device, and accepts my pin, then follows with the message above which I gather to mean it is locked to some carrier or other.
Running Android 4.0.4
Baseband: I9250XXLA2
Build number: IMM76I
Unfortunately I can't even buy an unlock code, because I don't know what carrier it thinks its locked to.
Maybe this is an indication of a deeper problem on this phone, not just related to replacement ROMS.
Any help would be appreciated.
Regards,
Jakrapup

No. People, if you don't know enough about the subject or enough to read the whole thread, don't comment. Some GSM phones are sim-locked like DoCoMo and evidently some Vodaphones and I'm sure more.
Also, there is a questions and answers forum. This isn't it.

I had same prob and used the do como solution it works 100%

I managed to sort my problem out without rooting, but it indicates something fishy is going on.
The phone was sold to me 'unlocked'. I contacted the vendor who promptly gave me an unlock code (I thought unlock codes were carrier specific... so which carrier is this code for? No idea, shouldn't even have had one!).
I'm starting to wonder if the vendor had bulk purchased locked phones from overseas (phone arrived in a french box), purchased the unlock codes, unlocked the phones, and then sold the phone on...
The vendor does tell me that the phone is supported by the local Australian warranty despite the french packaging, and the presence of an unlock code indicating it was purchased from a telco?
Anyway, problem appears to be solved, though I have no idea what triggered the lock in the first place.

Who did you buy the phone from? Was it kogan? And was the box sealed when u got it?
Sent from my Galaxy Nexus using XDA

Not Kogan,
I took a risk and bought from an Ebay store, rated as a top seller with a very high score, but you never know.
The box was sort of sealed, doubt it was the original seal. The seal was plain white, no writing or branding on it...
You get what you get with Ebay stores I guess
