T-mobile is a bit odd...

So I bought my HD2 2 weeks after they came out. Shortly after I tried buying an unlock code for my phone because t-mobiles service in my area is kind of come and go. Unfortunatly I have one of the 35777 Phones so after 4 attempts with 4 different sites failing at getting a code, I tried emailing tmobile to see if they would give me a code as they already told me they dont have service in my area. They told me to fax them a copy of my invoice proving I paid full price for the thing, so I did. About a week later they got back to me and said that due to the fact that I bought it from a site that was not one of their approved retailers I couldnt get an unlock code. So about a week and a half ago I went to a tmobile store and got the darn thing setup anyways. I get some service in this area, just not much. Now about 3 days ago, I get an email from t-mobile that looks like this:
T-Mobile Sim Unlock Request
Sim Unlock Reference: *******
IMEI: 35777*********
Unlock Code: ********
Thank you for taking the time to contact T-Mobile. Below you will see the Instructions for unlocking your HTC device.
1. Insert the foreign SIM card
2. Power on the device and the display should read "Please input unlock code"
3. Enter the unlock code and the device should display "Phone is unlocked."
4. Allow the phone to scan the network (or manually click on the antenna icon to do this)
It is very important that the instructions and SIM unlock code are entered correctly as listed. If you receive an error message while performing the instructions do not make any further attempts to unlock the handset. Please be aware that if an excessive amount of incorrect attempts are made, the phone will be permanently locked. You will need to verify the IMEI by pressing *#06# and contact Customer Care for support.
Thank You,
Sim Unlock Department
T-Mobile USA, Inc.
I kind of find this a bit odd. They tell me I cant get the number, then about a month later they randomly mail it to me anyway.

sounds kind of odd... have you always had tmobile or did you just sign up to purchase the hd2?

Neither, I had at&t before, Wanted to buy it and unlock it to use with at&t but in the process realized at&t's service is a bit of a ripoff. Atleast it is with standard plans. Wanted to try and use my hd2 with a gophone card but it doesnt seem to want to work.

SIM network unlock PIN for Samsung Galaxy S

Probably a silly question but I have the following problem:
I have 3 cards (Orange and 2 x T-Mobile). When I put either T-Mobile SIM in my phone, it requests a SIM network unlock PIN. I have the option of entering this in or clicking a dismiss button which will take me pass this screen but doesn't register onto the GSM network. This doesn't happen on my Orange SIM as this registers straight away onto the GSM network.
All 3 SIM cards do not request a PIN when I use them with two other phones that I have (HTC Hero and HTC TyTn 2).
On the SGS I have tried the pins 0000, 12345 and 1234 which are default PINs that I recall. I've checked the manual for the SGS and the literature that came with my T-Mobile SIM card and neither give any hints about a default PIN or about a SIM network unlock PIN.
I'm not sure if the PIN request is coming from the phone or the SIM card. I'm guessing it's coming from the phone but I don't know why it doesn't request this when I use my Orange SIM card.
I purchased the phone SIM free. The Orange SIM is a PAYG and the two T-Mobile SIMs are pay monthly contracts. I know all 3 SIMs work without PINs in my other phone.
Can anyone help? I'm assuming I'm missing something really simple but can't figure out what. I've already tried a dozen google searches with no luck. Please please help. I feel I'm being deprived of my 2 hour old SGS phone

I've now taken a video of the boot up sequence to show you what it looks like: http://www.youtube.com/watch?v=3D-RvvCK2bM
Can anyone confirm or refute whether this is happening on their SGS too? It seems like it's a Security Code on the handset but I can't find any setting for such a code.
Any help will be greatly appreciated.

Don't think your phone is actually SIM free... no issues here using any SIM I like (purchased from Unlocked Mobiles). Where did you get yours?

I purchases it from handtec. I don't think it is Sim free for the following reasons:
1. It was listed as Sim free
2. The box it came in also seems to indicate it is Sim free
3. There is no carrier logo on the phone or anything it came with
4. Seems to work with my Orange Sim card (which implies the phone came from orange if it was Sim free and this phone hasn't been released on Orange).
I'm guessing by the single thread reply that no one else has come into this issue before? And it's probably not just a simple default security code?

I don't know if this will help, but when I was asked for a sim code on a new Nokia phone, about two years ago, I rang Voda and asked for the pin code. In your case you would need to ask T Mobile.

I have the exact same issue with my Galaxy from Handtec which arrived today. I hope they aren't selling sim-locked phones as sim-free... Time to call Voda...

Ok, apparently it's a known issue. Just spoke to handtec, they say they got a batch of phones from Samsung which are locked to Orange. Call them for a replacement/refund. Don't mess about with the phone support line, it just points you to the website and disconnects you, call them and speak to sales. 01733 298500

Ah ok, that makes sense and which is why my Orange SIM card worked but not T-Mobile. I may have come to this conclusion if I had a Vodafone and O2 SIM knocking about.
Thanks for the info. Will be returning the phone for a replacement.

@n4nick: It appears as though you were right although the phone doesn't look like an Orange locked phone. Orange are notorious for plastering their big ugly logo on the physical phone and all over the software. They even put their logo on the box, accessories and manuals. This phone really looks like a SIM free version.
I wonder if the Orange locked batch were due to go to Orange for them to do their usual carrier differentiation before they then go out to customers.

Hi!, I've bought Samsung Galaxy S from handtec too and I get the same message: sim network unlock pin. I've just sent request to Handtec support.
What about you? Did you somehow unlock? Or did you change your phone?

Speak to Handtec about it and get a replacement or a refund as the item sent out is the wrong item. As mentioned previously, I believe the mistake was from Samsung as they sent a batch of Orange locked handsets as unlocked handsets which Handtec then sold accordingly. Handtec seem to be handling the whole mixup very well with good customer service so you should be ok.

Yeah I'm experiencing this issue as well. Phone worked fine for 7 days then today out of nowhere I get the SIM network unlock PIN alert upon startup. I contacted Handtec and this is all they had to say.
Thanks for your email,
Unfortunately this is an error with Samsung and we will require all of the items back, postage will be covered once back and confirmed it is an orange locked device but we will require this back to replace it for you.
Please advise,
Kind regards.

I can't be bothered with sending it back and being without a phone for atleast a week.

Legally they have to give you a full refund including the postage cost for both ways. Therefore you could purchase a new handset while you are in the process of getting a refund for the existing one. You'll know if it is an Orange locked phone because there was one or two Orange specific applications pre-installed on the phone.
If it was working before and not now then it's possible it could be a different issue though.

I work for t-mobile and samsung sent us some unbranded phones that were locked to orange by mistake. That chances are we wernt the only ones to receive them
Sent from my GT-I9000 using XDA App

had this problem myself on O2
went to store to use their phone to ring around (they were sorry)
after time on the line with O2 support they had no answers, so i rang samsung
samsung took literally seconds on the phone, i said about the 'sim network unlock pin' and he simply turned round and said its dead, a dead chipset thats in every phone they sent out in the last week, i was told this on friday 11th
samsung then spoke to the staff at the O2 store and advised them to mark all other galaxys they had as 'dead on arrival' and return them and for others to do the same
looks like a big batch issue so best thing u can do is send your dodgy one back like i have done, hopefully this replacement will work

I just got the Network Unlock PIN Message myself randomly after a reboot 7 days after purchase.
Has anyone tried using a TurboSIM to see if it works?
Sad thing is it was working one day and then broke the next.
Pretty bad that we have to pay postage to get their doa replaced. ( Specially considering that's about $50 for me. )
EDIT: Does anyone know what the STOCK firmware was when you got your handtec handset? ( From what I can tell it could be XXJF3. )
EDIT2: Success! After contacting Handtec they sent me a code to use, it seems to have permanently network unlocked my phone.

After a few emails with Handtec they were able to provide me with an unlock code after giving them my IMEI number. All is good again

I have a similar problem with T959 from TMobile USA. The phone was obviously locked to TMobile but I got the code from TMobile, entered it and phone was unlocked. My customer took home, used it for about a week and now the phone is network lock again and ask for network pin. So I enter the same code that was used to unlock it but now it DOES NOT work. So strange. But this happened before on other android phone and it worked, just re-enter the code. Anyone has a solution yet on this problem?

aaarrrggghhhh!
I have same problem but.... the unlock code Handtec sent me does not work
I have tried every method I can find on the internet to enter the unlock code (eg #0111*code#, #7465625*638*code# and even #7465625*638*# which pops up with a seperate box to enter the unlock code) and each time it fails. I've even done this after various full hardware resets.
Hantec have said the phone might be faulty with a software problem and to send it back to them.
I am in Cyprus and its going to cost me 50 euro to send it back. If I had paid an extra 50 euro on the Handtec price I could have bought it locally! Doh!

To enter the code you should put a SIM in, and start the phone, it will ask you straight away...
If you attempted to enter wrong codes too many times it will stop asking you and your phone is permanently locked until you return it to the manufacturer.
Oh noes, mine better not relock... :\
Just out of curiosity, how many 5's does your code have?

Urgent AT&T network problem: Atrix 4G Android

I am urgently in need of someone who can solve this network problem I have been having. Right now I can not access any mobile network with this phone.
I am using an Atrix 4g unlocked and rooted.
Basically, my problem is that my phone has been asking me for a "SIM network unlock PIN" every since my time in Italy.
I recently went to Italy 2 weeks ago, and came back yesterday. On my first day in Italy I bought an Italian SIM card from the Mobile Network company Tre, a company similar to AT&T. When I replaced my AT&T network card with the Tre one, it asked for the SIM network unlock pin. Seeing that I did not have a code on me at the time, and after trying several numbers given to my by Tre, I replaced the tre card with my original AT&T SIM card. I later learned that my phone was not international and I unfortunately did not call AT&T ahead to unlock it, causing the phone to lock network access. I learned that this is a security feature in case your phone is stolen.
I'm asking for your help because I spent literally over an hour with tier one and tier two support of both AT&T and Motorola technical support all telling me the same BS.
Before calling any support numbers, I went to an AT&T branch, and I told them the situation. They replaced my AT&T SIM card with a new one, yet the phone still asked for the SIM network unlock PIN. They then told me to call support and ask them about a subsidy unlock code. AT&T phone support gave me multiple codes to unlock the phone, but none of them worked. All of the SIM and IMEP numbers on the phone were correct in their systems too. After telling me exactly the same thing as tier 1 support, AT&T tier 2 then transferred me to common Motorola support tier 1 support. Motorola only told me to hard reset the phone, which I do multiple times every time I update your firmware anyway. The last hard reset I did to my device was literally 30 minutes before I called technical support. They then told me that the only thing I could do is to replace the phone under warranty with either motorola or AT&T.
However, I am in a pickel becuase my phone is completly unlocked, rooted, has CFW/kernel, etc...and I think that wards the warranty.
I have been using this same firmware ever since I got this phone during the last summer, and it has been working perfectly. After I put in the Italian SIM card, the network locks. I have no where else to turn but to an expert here on xda.
Is there anything I can do? The only thing I can think of is to tell my story to a nonobservant AT&T guy over at a store and ask him to replace it. However, I don't know what would happen if they found out my phone is unlocked and they gave me a new phone under warranty before realizing this...
Thanks

Ahh, perm SIM locked.
Pretty sure that has to go back to the manufacturer to be fixed, if it can be fixed at all.
Just go ask for a replacement, they shouldn't be able to unlock it anyways.

thanks for the reply.
However, two things:
1) I thought it might be permanent, but I was not sure. Back in Italy I remember the phone giving me a certain number of try's, so I now that I think of it I might have exceeded that, causing it to perm lock. Is there any other way in telling if it's perm locked?
2) Also, one of my concerns is that AT&T will see that my phone is unlocked and rooted and all of that, thus warding the warranty and the replacement. I'm thinking that maybe after I give them this phone and I get a new one, they look at the old phone in the future and will see that its rooted and unlocked. Is this possible or what?

1) Just putting your sim card in and having the phone not respond pretty much sums up the sim lock.
2) I would at least revert the phone back to stock. AFAIK, unlocking the bootloader burned some sort of efuse so returning it back to a true factory state is "technically" impossible, but I do remember seeing that you could at least relock(?) and removed the unlocked notification at boot. I believe you should still be able to access the phone even when the sim has been locked, just start it without a sim card in place. If you can bring it back to an AT&T build, I think you'll be okay if you're still under warranty.
Just remember that next time you travel, either have an unlocked GSM phone or get a sim subsidy code from the carrier that the phone is linked to.

Would getting a code from cellunlock.net work? Or is their code the same as the ones given to me by AT&T tech support?
AT&T tech support gave me three '8 digit numbers', which were randomly generated. None of those worked. DO you think a cellunlock number would work?
Also, I am reading up on some forums saying that people in my situation (who's phone does not accept any SIM card and still askes for the code), can get the phone to accept some codes by reverting to stock firmware and radio. This is by .sbf though....

If things haven't changed, I believe the sim subsidy unlock would only clear the phone for the next foreign sim card placed in the phone whereas a real unlock code would completely unlock the code. Once your phone has been locked though, I don't think that code will be of use anymore.
It wouldn't hurt to try to sbf back to a stock build provided you follow the proper instructions to not get the x1000 hard bricks. Aside from trying that, I would think your best bet would be to just get the phone exchanged under warranty.

SIM lock
Looks like you have locked your SIM. Since you have rooted your phone you voided your warranty , best bet is look for SIM unlock code from online probably ebay will give you cheaper options, try them if worked great if not then there is a tool to root/unroot any android device, I will post the download link once i find. restore the device to factory settings if it permits and unroot back . then claim for replacement.

Hi i just unlock my device after hours of investigation. You have to change the baseband. Here is what you have to do. Flash the baseband to the ones from brazil (search in google sbf not the zip ones), after the process you can put it back to the usa at&t radio. Ones you change to tha brazil radio (wipe always before changes radio), put one sim card of another provider and voila, the code will work. You need to have your phone with no registration of motoblur at all.
I hope it will help you.

Sim Unlock Sprint Galaxy S5 for use on the AT&T Network?

Hello everybody, sorry if this has been asked I tried searching everywhere and have come up with nothing that has been helpful to me. I am new here so if I'm posting in the wrong place I'll be happy to remove this.
I will try to provide you with every detail but my main problem is this: I have obtained an unlock code I received directly from Sprint for a Galaxy S5 I received from a friend. The friend made sure the device and his account met their qualifications, and he received a six digit "MSL Code" that he was told is the unlock code.
I have been told by Sprint, AT&T, countless YouTube videos and forums that the sequence for unlocking this phone is as simple as 1.) Entering a foreign sim into your device. 2.) When you turn the device on you will be prompted to enter the sim unlock code. 3.) Enter the unlock code and your device will be unlocked.
Of course it's turned out to be way less simple than that. My most obvious problem is with step #2. I am never prompted to enter the sim unlock code and instead only receive the message "Invalid Sim card."
Okay here is a back story if you want more details: I am on a family plan with AT&T right now that I believe is a good deal and would not like to switch carriers, although AT&T hires some of the biggest idiots I've ever encountered to work in their retail stores and tech support. I have been tempted to switch to Sprint because throughout all of this they have been the only ones to give me straightforward information and any help at all so far.
The Galaxy S5 in my possession meets all of Sprint's requirements to be unlocked and the previous owner received the unlock code directly from Sprint. It should be good to go.
I went to AT&T retail store with the locked device and unlock code for assistance and to make sure the process would go smooth and easy. The first time I was told it's impossible to sim unlock a phone and all I can do is sell the phone on eBay. I called tech support after this and they told me my problem was that I was using the AT&T sim card from my old HTC One, that SIM Card would be incompatible with the Samsung, so therefore I am receiving an "Invalid Sim card" error. The second time I went in I requested a sim card for a Samsung Galaxy S5 because AT&T tech support told me the SIM card in my HTC will not work. The dude grabbed an empty SIM card and gave it to me without asking me for my information or anything about my account and when I asked him about this he told me that it's not necessary, "SIM cards don't have any memory or carry any information on them for the phone to read other than what service the phone is supposed to use". I honestly don't know much about cell phone technology but I knew this was bull**** but he was no further help after I told him I think he might be wrong about that. I called AT&T tech support and they told me that guy was an idiot and to go back to them and request another SIM card.
I don't want to go back into that stupid store until I'm absolutely sure what the **** I need to do to get this stupid phone to work with my AT&T account. Please educate me on how this process works and what the correct steps I need to take are. Thanks a million times in advance for whatever help you can give me, and again let me know if this is being asked in the wrong place I'm still new here.

Galaxy S5 Neo - Phone relocked and now Network unlock request unsuccessful

I have a SM-G903W phone (Samsung Galaxy S5 Neo Canada version). It was a replacement phone I got for free from my dad who is on Rogers. He bought a new phone and used it and gave me the replacement phone. I assumed it was locked to Rogers and called them for the unlock code but they wouldn't give it to me because the replacement phone had never been on their network, and they have a 90 day policy. There's a local tech shop that offered unlocking services, so I had it done there. It worked great in different countries.
I recently moved to the states and the phone worked fine for a week under UltraMobile/T-Mobile. Then somehow one morning I turned on the phone and it was saying "Invalid SIM, enter sim network unlock pin". The phone somehow locked itself again! I called the tech shop I used in Canada and they gave me the unlock pin for my phone. I entered it and it said "Network unlock request unsuccessful". Now, I've read on this site that even with the correct pin this error can sometimes come up, and there's a bunch of dial codes people posted. None of them work for my phone, they were all written for Galaxy S5 or Galaxy S4. I haven't found anyone address this issue on the S5 Neo.
I asked the tech shop what I can do and they said if I bring it in to their store they can hard unlock it for me, but I'm not going back to Canada for a couple of months. I haven't found any local unlock stores here except one which wanted $100 for it, and the store seemed sketchy. I called Rogers to see if I can get an unlock code from them, maybe it'll be different, but they claim my IMEI isn't in their database! I'm not sure how that can be (see next post)
What can I do? I don't have any custom roms installed, although I rooted the phone in an attempt to get it unlocked again. It's running Android 6.0.1

Update: I purchased from Rogers the unlock code, and they gave me the same one the tech shop gave me...there goes $50. On the bright side I've confirmed I have the right unlock code, but the phone still says "Network unlock request unsuccessful". Would flashing a stock rom help?
EDIT: I flashed a stock rom and it didn't help (used MTA-G903WVLU1BPF1-20160602043310), 6.0.1. I don't suppose a 5.x version would do much difference?

Hi I have had similar experience with network unlock and generally I find that the original stock firmware will work so yes I imagine that the 5.x will help

Hi,
Did you ever get a solution to this?
I have had similar situation except I updated mine with smart switch and now cant get a network.
Ive been searching likead amd camt find a answer just the same reset networl ect and they aint working.
Amyone reply if you know as I dont want to start a new thread when ones already up.
Thanks.
