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.

Hey this metod works with an lg p930 too?
Hello there,
So I got a USED Galaxy S4 from someone on kijiji
The phone is from rogers, and still locked to rogers/chatr
Iv been using the phone for about two weeks with no issues at all.
Last week, just in the middle of the day
I was taking the phone out of my pocket, and I noticed that it says ' unregistered sim'
On the lock screen and status bar
Tried to restart the phone and pull out the battery, nothing happened. Tried a NEW chatr sim card- no luck.
Went to rogers yesterday, tried 4 different sim cards
Didnt work.
I stuck with the "unregistered sim" msg, which not allows me to use the phone.
I tried to look for an answer around the net, and couldnt really find someone who have a similar issue.
Any ideas?
Is the phone might be stolen?
Is therr anything to do about it?
Thank you!
Sounds like you're the victim of insurance fraud. The guy sold the phone and then reported it stolen. He gets paid twice. You should have insisted that the phone got transferred to you at an at&t site, or whoever the carrier is
If the phone is blacklisted, another possibility is that the phone was stolen directly from Rogers or an authorized dealer. Phone will work for a while until the IMEI is blacklisted for that carrier.
Try to unlock the phone and use a different carrier sim card like Telus or Bell.
You could have a defective SIM card slot. As to my knowledge no carrier in Canada currently blacklists IMEI's (I could be wrong though). An easy way to check is just to call Rogers and provide them the IMEI and they can tell you.
I work for a multi-carrier dealer and I know that for Telus if you get their replacement plan (the one where they charge you monthly for) and you report the phone lost/stolen they will blacklist the phone. Rogers has the same replacement plan but whether they blacklist the phone or not I don't know. Try putting a sim card from a different carrier and see if it works. If it does then the phone was most likely blacklisted by Rogers/Chatr/Fido.
They would tell you that the phone is blacklisted. I am going with a faulty sim cradle on this one.

Thank you guys
Thanks a lot guys, very appreciate your fast and helpful comments!
Ill definitely try to unlock the phone and try use it with another carrier!
reason for unregistered sim error
You have samsung galaxy mobile and you have bought it from someone else.
Here is most possible reason is the original owner might have not paid any due amount or some one complaint about the phone from insurance company that it is lost or stolen.
It is locked phone still you can try another sim from same carrier like roger.
Or if you mobile support dual sim then try to insert the sim to another sim slot.
Or you can also try to insert sim to another mobile which is not locked. On unlocked phone if you get the same sim unregistered error. Then contact your sim provider and they will ask for your id proof. And photo. Just submit it and your sim will be active.
[Q] (Unlocked) AT&T Samsung Galaxy S4 SGH i337 gives MM#6 error for MetroPCS SIM Card
Hello everyone. I feel that I have a rather unique issue here.
My sister recently bought an AT&T GS4 from eBay to use here under a MetroPCS service. I took it to a local phone shop in order to have it unlocked. I am not a noob when it comes to rooting/unlocking/ROMing/etc. since I've done so and experimented with my Verizon HTC Rezound. Since I've nearly bricked my Rezound three times, I decided that I should leave it to someone more experienced.
I took it in, within 2hrs the guy had the phone unlocked for me. He put in a Simple Mobile SIM card, I called my own phone and it worked. I take it to Metro PCS to have my sisters current line transferred to a SIM card to use the GS4 with. The problem is that whenever the SIM card is put into the phone and turned on, it says Phone not allowed (MM#6). I then proceeded to look up the IMEI to see if its blacklisted. I checked online and it said that it was clean. I also went to a corporate AT&T store to have them check if it is indeed blacklisted and they said that it is clean. While at the store, I decided to look through the phone for anything unusual. After checking the Status of the phone, I find that the IMEI value is 0. I then hit the *#06# menu and get a popup which says IMEI 0/04. I let the Sales Rep know and ask him if that could be an issue and he said that whoever I took it to might have messed up with the root and that there's nothing they can do since I don't have service with them.
I thought that maybe the phone wasn't connecting to the network because it wasn't set on the GSM radio so I used the *#*#4636#*#* menu but yet nothing happens. I added the APN values for T-Mobile (works for MetroPCS) and still no luck. I even tried factory resetting the phone but whenever I add the SIM card, I keep getting the same popup. In the Service Menu (*#0011#>>Back>>Key Input: 1) UMTS Main Menu, I hit [2] Version Info >> [1] SW Version >> [1] Read IMEI >> and it says "IMEI NOT ACTIVE."
I started looking around the net to see if I can restore and/or repair the phone and I've seen YouTube videos of people unlocking the code by using the Service Menu. Currently, I'm looking around the XDA Forums to see if there is anything I can try out. I'd appreciate the help. I do not want to install any ROMs on my sister's phone unless I absolutely have to. If anything, at the moment I'm trying to flash back to stock. Does anybody know anything about this issue? Also, if I am posting in the wrong area, I apologize for the inconvenience.
You need to put the original imei back to your phone, because the guy unlock the phone for you he messed up with your phone 's imei that why after unlock the phone shows zero imei

You're not alone on this one. I bought an AT&T S3 and having the exact same issue as you are. Here's my story...LOL. I met with a gentleman at the local AT&T store. We checked the IMEI, verified it was in good standing. Since he's the original owner, I purchased the phone from him. I use my MetroPCS SIM, and I get the same "MM#6" code you described. I'm very familiar with using AT&T phones on MetroPCS. I have transferred two NOTE 2s and an S4 to Metro accounts with no issues at all. BTW...the IMEI is still in good standing & when I insert a MetroPCS SIM, the IME still shows in the AT&T S3.
My Phone specs: Samsung Galaxy S3
Carrier: AT&T
Version: Android 4.3
What I've tried:
Downgrade to 4.1.1 (Unfortunatley, bootloader can not be downgraded)
There's two things I can think of...The Android version has something to do with it. Or...I've found out that my S3 was used overseas. And since your phone was from Ebay, theres no telling how the phone was used.
My next step is to purchase a clean SIM card from MetroPCS and have transferred to my account. I'll keep you posted on my findings. For now, I'd go to AT&T store and use their SIM and see if your IMEI comes back. Or downgrade the phone if possible and start from the bottom and work your way up.

Heres my update. MetroPCS SIM card is "married" to each IMEI/PHONE. My phone in question (the ATT S3) was not correctly associated with my account. I called MetroPCS customer service (1-888-8METRO8) gave them the ATT S3 IMEI and the SIM number. within 10 minutes, the ATT S3 was up and running. I hope it helps.
Please provide feedback.
I had a similar issue with MM#6
I called MetroPCS - informed them I was receiving MM#6 error and asked them to 'activate' my phone.
Gave them my IMEI and within a few minutes, I was golden!
WORKED
Thank you for your update worked perfect...:d:d:d

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.
Hi
I've bought a second hand S7 Edge ATT phone on a kind of craigslist in Denmark (i live in Denmark).
When i came back at my place, i discover that the phone is an AT&T phone and that my simcard doesnt work in it. The simcard is seen as there is the linked application of it and the phone asked me the pin code but nothing to do.
Then i search and i went on the AT&T website to unlock the phone. I got an error message:
---
""Looks like you haven't paid off your device yet. Follow these steps to pay off your installment plan. Then, wait 48 hours before you submit a new request."
---
I spent then 1h chatting with ATT and without any info about the original owner, ATT cannot help me... so basically i'm stuck.
The only info I've is the IMEI number, that's it.
So here are my questions:
1 - Is there a way to unlock an ATT phone that is not "unloackable" by ATT because of this pay off issue?
2 - If yes, is there a way to do it free?
3 - Is installing a firmware G935U instead of the G935A would solve the issue?
The phone is quite old now so i dont want to invert money in it.
Thank you for your help
