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

You can follow the guide to have the phone work and it will fix that.

You need to use a foreign Sim card, not an American one because Verizon disabled access to all other American gsm networks

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.

[Q] Problems unlocking Galaxy Note 3

I just purchased a Galaxy Note 3 (SM-N900A), full-price, off-contract, from AT&T Wireless. I used an existing GoPhone (prepaid) account/phone number to activate the phone. The phone works (voice calls) with the AT&T SIM. However, I want to use the phone/device on aioWireless. I have a microSIM for aio. I have purchased an unlock code and followed the unlock instructions. I received a "Successful unlock" message after entering the 8 digit network code. However, I cannot make phone calls (or use the data plan) when the aioWireless SIM is installed. When dialing a number with the aio SIM, I get a recorded message that the service has been deactivated, and to contact AT&T.
When I try to verify whether the phone has truly been unlocked by typing *#SIMLOCK# nothing happens. If I then push the CALL button, I then get the message: Connection problem or invalid MMI code.
Any clues what is going on?

Do you maybe have to use different APN settings for the two networks?

I have no idea.

I would look up the APN settings for AIO and input those (Settings>Connections>More networks>Mobile networks>Access Point Names)
You could always just call AIO customer service or walk into a store and they should be able to help you out.

I thought APN is just for data and has nothing to do with his inability to place calls! especially that he is getting" service deactivated"
I would check the AIO account if its working first.

APN is indeed simply meant for DATA and MMS
Your phone is functional with TEXT message and CALL's WITHOUT even a single APN setting set up
The main problem here is compatibility. OR the SIM card
SOMETIMES you have to leave the sim card inside your phone for at least 5- 10 minutes
At one time it took me 20 minutes for a sim card to be recognized, then I got 4G
It depends on the network.
But if all fails, just call your new network and try to get a new sim card
As long as your phone is fully compatible, and you know it, there are ways around it.
Hope this helped!:good:
The *#SIMLOCK# and various variants of it no longer works starting from the GALAXY S3 and Above (Not even all S2's accept this code)

AT&T unlocked 2014 x not working on tmobile

I have an unlocked AT&T xt1097 but it won't register my T-Mobile Sim card. It registered for about 3 minutes, got a welcome to T-Mobile text and that was that. My phone number shows up in settings, but it shows I have zero service. I've reset, and rebooted several times to no avail. My sim works in a nexus 6 so it's not the sim. Imei os clean. Does anyone have any ideas what it could be or how I could get it to work with my T-Mobile sim?

When you say unlocked, unlocked Sim or unlocked boot loader?

sim unlock. As far as I know there's no boot loader unlock.

Could it be that the imei isn't in T-Mobile's data base since it's an at&t moto x?
Edit: went and put the imei in to tmobiles imei checker and it couldn't figure out what device it was and if it was okay to use on their network. Now I just need to verify with T-Mobile and see if they can register the imei.

did you ever get it to work? i am experiencing the same issue. it connects to my friends AT&T network fine but with t-mobile it just says "cant register" etc,etc.

Change the APN settings
I have had a problem like this with my unlocked phone and AT&T, but when they set it up in the AT&T store they fiddled with the APN settings. I had to do the same to get my wife's unlocked Lumia 635 to work on the T-Mobile network. Try the values used in the link attached and see if it works.

I was able to connect to tmobile network some times, able to make calls. No data connection at all. I played with APN settings and everything else. any help..?

I have an unlocked ATT x1097 and it works just fine with tmobile.
You just have to MAKE A NEW APN SETTING.
When you put a tmobile sim in it, it will automatically create a couple of T-MOBILE apn settings. Just leave that as is and create a NEW APN SETTING with same info you can find from Google. Select that as your data apn. And reboot the device for the best result. It should fixed the problem.
For those of you whose sim does not register into tmobile network; i think it could be one of the following reasons:
1. Original ATT modem does not work well with tmobile frequency in your area
2. The device is locked (stolen, non-payment, etc)
3. The device is broken
4. Your SIM card is damaged
As long as you are at the home screen with tmobile sim, your phone is GSM UNLOCKED, and it iwill never lock again.

Just wanted to say thank you. My T-Mobile SIM wouldn't connect and I even went to the T-Mobile SIM store to get a new SIM Card but it didn't help. As you stated, adding a new APN setting was the only thing that worked.
For those of you who want to unlock your Moto X, I purchased a code on eBay for about $8 and received it within 6 hours. I would post the link but I'm afraid it might be considered spam.

What type of data signal are you getting? LTE?

Nice. Where did you get your unlock code?

I don't know about OP but I have always used swiftunlocks and have had great luck. Got my N6 from ATT unlocked through them without issues as well.
http://www.swiftunlocks.com/unlock/motorola-at-t-tmobile-worldwide
I noticed that sometimes phone picks up apn without issues and sometimes you have to restart so I just restart every time I make a change to be on the safe side.

Just in case anyone else has the same issue as OP, you should use the
Code:
epc.tmobile.com
APN, NOT the
Code:
fast.tmobile.com
one.
The fast.tmobile.com one would not let me register on the network. epc one did immediately.

Hey, I know this post is kind of old but I am currently having the same problem with my moto X 2014 going from At&t to T-Mobile, were you able to get it fixed and if you did, what did you do?

Any luck? I've just come accross the same issue. Got phone unlocked, and bought a new sim and activated. I'll get like 3-4 minutes of service randomly here and there, but about 99% of the time no service. Tried multiple variations of APN settings that I've found online. No luck

Fixed all my seriously annoying connection problems by flashing the 4.4.4 modem.

I just gotta upload the 4.4.4 modem from my pc, will do that later for you.

Neither one works for data... Just got it unlocked from swiftlocks and I can get voice, but no data :crying:
Someone help!! ...plz

Anyone ?? T-Mobile reps are mostly useless, and keep telling me that my device may have been ' re-locked ' to AT&T after a hard reset !! I know that's not the case because I've thrown in a Vodafone sim and it recognized it ! The sim unlock was purchased from SwiftUnlocks and the phone took it in one try w/o any issues!
Now, I can't even get voice to work... All I see is ' No Service ' and when manually trying to register with T-Mobile, it says ' unable to connect to the T-Mobile network. Please try later '
Someone please help out!!

No signal/voice/data - Restricted access changed. Voice service is blocked

Just as the title says, the phone was working fine then suddenly it lost all signal and went into some kind of restricted mode, it's a friend's phone and he is almost 84 years old.
I have flashed the latest firmware and factory reset to no avail, also changed sim cards and here comes the weird behavior:
I don't have a standard-sized sim card so I had to take it from my USB LTE Modem, it's from another carrier and the phone detected the sim card, went with a full -77db HSDPA signal but data doesn't work at all, it seems to be disabled on status, even configuring the proper APNs it refuses to work. Can't test voice and all my other working sim cards are nano.
Inserting any other sim from another carrier results in no signal/restricted access but the phone still downloads the Internet/MMS configuration.
Have tried setting it manually to WCDMA and GSM, nothing seems to work, only my data sim worked so far *without the data*.

Maybe the IMEI is banned for some reason?
Never heard of this issue until now
Have you tried to flash a firmware that aren't from any carrier?

Yes I did, flashed the USA unbranded kitkat rom.
Just got the chance to test with two sim cards from different carriers:
Carrier #1: Registered on network, no data traffic, voice call drops just after trying to call, signal ok
Carrier #2: Registered on network, data traffic seems ok but can't navigate, shows H+ and proper APN and traffic arrows activity but when you try a call it says "Mobile Network Not Available"
Can't send SMS, they stick with a "Sending" status and wont get past it.
This phone was purchased unlocked without a contract, can't see how the IMEI could be banned, plus we do not have regularization for IMEI ban in my country, it's currently a mess.
On a side note it does not detect the sim's phone number which it does on any other phone.
Maybe it's some hardware related issue?

The sim number information depends on the sim itself, most carriers register this information within the simcard so when you go to status you may retrieve your own phone number but I have seen sim cards without this info. The sim cards I tested do have this information and were available on a Galaxy S5 and Xperia Z1 but this E1 fails to read this information which kinda indicates a problem. I don't remember the codes for debugging the sim and network info or I'd give that a shoot.
I will try a custom rom, maybe a different kernel and see if the behavior changes any bit.
I am bidding on a Z1 Compact for this friend, should be a proper replacement and a hell of an upgrade, just concerned about E1's loudness which is certainly superior.

Interesting, I also get this if I don't reboot my phone after like 5 days.

VERY Odd Problem - SIM Card Locked, Requesting PIN. Only on This Phone & SIM Combo

VERY Odd Problem - SIM Card Locked, Requesting PIN. Only on This Phone & SIM Combo
On each boot, the phone asks for "SIM network unlock PIN", and otherwise will read "No SIM card" in the notification bar.
What's odd however is this phone is unlocked. It's an AT&T Nexus 6, and was previously working under Cricket Wireless. The SIM card is from Mint Mobile, and works with my unlocked LG G5. It's only this phone & SIM combination together that's causing issues.
Trying to access APN settings gives the message "Access Point Name settings are not available for this user".
I've tried factory resets, as well as full flashes back to stock, etc.
I've never encountered this before, if anyone has any ideas or input I'd appreciate it.

Sounds like it is NOT unlocked. Since Cricket Wireless is an MVNO directly owned by AT&T, it makes sense to me that an locked AT&T device may work on Cricket.
Test with a friends SIM card. The Nexus 6 works on all carriers in the United States- Sprint, Verizon, Tmobile or AT&T. If their SIM card does the same thing, yea this confirms that it's locked. Buy an unlock code, it should only be a few dollars I reckon.
edit: also please note there is a difference between an unlocked/locked bootloader and unlocked/locked network. They are NOT mutually exclusive.
