I recently had my phone get stuck in a bootloop on Infection after having it run fine for over a year. So, I followed the the steps here: http://forum.xda-developers.com/showthread.php?t=2509770 and everything went fine until flashing the last OTA update. When asked to put in my pin code for the sim it states the first time I am asked that I have 0 tries left and I need to use the PUK code to unlock it. The PUK code will not unlock it though. I am for sure using the right code. Every other step in the upgrade process worked fine with the GSM sim card. I ignored this error at first and flashed a JB Rom and a KK Rom and the sim card was not recognized in either case. I had no cell network at all. I downgraded to the last RUU and the sim card was back, the first OTA worked as well, and again on the last OTA I get the same sim card error. I'm in Germany with a verizon rezound I bought in the states, if that matters. Please help....

Hi there,
I rooted my phone. I've installed Cyanogenmod 7 and enjoyed it. However, it is SIM locked. I purchased an unlock code... but now I can't enter it.
This person had the same problem:
http://forum.xda-developers.com/showthread.php?t=1313393
Cyanogenmod does not prompt to unlock even with a foreign SIM card.
The solution was to revert to a stock firmware. Which is great... except for the fact that my phone's model number is:
i5500m.
It's the dreaded Canadian version. I can't find firmware for it anywhere. I've tried Check FUS:
Product Code: GT-I5500YKMVMC
No firmware info retrieved for given data.
Generally it seems like I only have two solutions... and one failure.
The first solution is to find a stock firmware for this phone. Or receive a backup from someone who has the stock firmware with Clockworkmod.
The second solution is to enter the unlock code without the prompt. Is there a way, an app, or a hack to do something like this?
My failure is to accept that there's no reverting. But I don't really want to do that.
Oh, and thank you for welcoming me into your forums. XDA Developers is a really amazing site. I've thanked it plenty of times for saving my ass.
Thanks for your time,

Look closely at the latest changelog and notice that point 12 states -
"Network: SIM lock messages will no longer be ignored. This may help people who have problems using SIM cards that require a PIN unlock."
Good luck

Thank you so much! I missed that update by only two days. I'm sure this will help many people.
I'll edit this post with my results once completed.
Thanks again!
Sacrosaint.
---------------------------------
Results:
So I updated the ROM. I did not do a data-wipe. I inserted a foreign SIM card. It says it's connected but I'm not getting any service... I don't believe it's unlocked, as I haven't entered a code yet.
Perhaps I should do a data-wipe and retry. I'll repost afterward.
---------------------------------
Potential Final Update:
Odd! I inserted a Rogers SIM card into my phone running CyanogenMod and although no unlock code appeared... it worked. Also known as: my phone is unlocked.
Some interesting thoughts concerning this:
My phone model is i5500m. It comes locked to Bell or Virgin Mobile in Canada.
Upon trying the bml5 unlock method, my code came up as "01234567." Others experiencing this problem concluded that the phone was hard locked.
However, it would appear that flashing this ROM effectively removed the SIM lock. That means that originally, the SIM lock was a part of the firmware. That is slightly scary. I wish I would have come to this conclusion earlier, however, as I paid a premium of $40 dollars to unlock it (at least I supported a local business.)
So: for i5500m or Canadian Samsung Galaxy 5 users to unlock their phones, they must simply root and flash a custom ROM. Originally mine was from Bell, and it has worked with a Rogers SIM card. I'll possibly update this tomorrow when I try the phone with a Koodo SIM.
Hope this helps someone out there.

Sacrosaint,
I have an unlocked GT-I5503YKAINU running baseband I5500LUYJP2 and ROM CyanogenMod-7.2.0-RC0-galaxy5-v1.9. I inserted a Virgin Mobile Canada SIM card and do not get Service. With a Rogers SIM card, I do get Service. I spoke to people at Virgin and they said it's because my phone doesn't support HSPA+. The reason it works with Rogers is because it supports GSM.
I'm wonder if there's a way to install the baseband firmware from GT-I5500YKMVMC and still use CyanogenMod-7.2.0-RC0-galaxy5-v1.9?

What the representative said was true.
Virgin is both HSPA+ and CDMA. The Galaxy 5 IS a GSM phone. Its radio will not work with other frequencies.
You will want to go with Bell, Rogers, Telus, Fido, or Koodo, the GSM suppliers, my friend.
Just purchased an HTC One and an unlock code, and upon inserting a T-Mobile sim card into the slot, I do not receive the Sim Network Unlock Pin request menu, instead I receive an error Phone Not Allowed MM #6 which I've read means the phone has a bad IMEI, but the phone works flawlessly with my AT&T Sim card meaning it cant be a bad IMEI. Am I just a noob and missing one simple step? I've rooted hundreds of phones and im coming from my HTC One X rooted and unlocked, so if anyone can help please respond as soon as possible, as I said I already have my unlock code, just unable to attain the input menu, the phone is NOT stolen.
Thanks so much,
Z?

I also recently bought an AT&T HTC One from Craiglist. When I inserted a T-Mobile SIM card it prompted me to enter the unlock code, which I entered then the phone rebooted and it no longer asked me for the unlock code.
BUT, i was not able to get a signal and got the MM #6 error.
The error apparently can be from the phone being black listed. in my case the phone is not blacklisted.
The other reason, it seems, since the phone was bought from AT&T with subsidies, AT&T will not allow the phone to be used on t-mobile.
Had the previous owner requested the unlock code before selling it then it would have been unlocked.
For now, I am using it with aio for $40/month which is pretty good.

Hi, about a year ago I got a G925T and unlocked it to use on ATT network. Now, I've been gone the last 5 months or so and since the second or third day coming back my phone messed up and developed the FRP issue. I got that sorted out and have since used odin to load 6.0.1 and then installed TWRP, root, new kernel and rom.
But even after all this, I still have the network lock issue. IT says to me that network locked sim card is inserted. Is it possible that the issue is with the sim card not the phone? What could possibly cause the phone to re-lock itself? Any thoughts/suggestions?
Edit: Looked up the IMEI and it is clean, was when I bought it and seems to still be now so I don't think that is the issue.
I flashed my Note 8 when I first got it (before I had the unlock code). I flashed it to XAA/U1. Well, I got the unlock code a few days later and when I popped in a foreign SIM it simply says "Invalid SIM card inserted" "This SIM card is not supported" with no prompt to enter SIM unlock. At the time this was not a huge deal I kept the unlock code and have been using it since. Today I swapped carriers. Now it matters.
Phone is showing model # SM-N950U1.
Bootloader shows Carrier: ATT
Baseband is BRA5
I flashed N950USQU3CRC2_N950UOYN3CRC2_ATT
It still doesn't have the carrier bloat or prompt me to enter a SIM unlock.
Thoughts?

Switching carrier guide to change CSC code to ATT...then flash ATT firmware
Let me give everyone a heads up who may be an idiot and do this.
I had to downgrade from Oreo to BRA8. I had to do the carrier switch and change the CSC file. I then had to flash all AT&T bloat. Then pop my SIM in. Use my unlock code. Then reflash to XAA.
Thanks BlueFox helped me through the whole ordeal. What an effin nightmare. All this was in the name of gaming the carriers for "free" phones.
I am still trying to get my XAA flash going, but this was a solid 5 hours of effort on my part. Shame I will be updating to the S9+ within the next month or so.
Phone displays "Network Locked SIM Card" Inserted after flashing a stock firmware
I recently uninstalled Magisk, and was able to only boot into download mode after. So, I downloaded a stock firmware for my s9+ 965f and flashed it through odin (using AP,BL, CP, CSC(didnt select HOME CSC). But after rebooting, the phone displays "Invalid SIM. Network Locked SIM Card Inserted".
It asks for PUK code to unlock the phone and the cellular service alone is not working now. My phone is already region unlocked and I have been using it for the past 8 months. Has anybody got this issue and any suggestions on how to solve it?
Previous OS: soldierx rom for 965f v12 on Oreo
What I did,
i) uninstall all modules in magisk,
ii) uninstall magisk,
iii) phone auto-reboot
iv) Now phone stuck in download mode. Cannot boot it
v) downloaded stock firmware G965FXXU2BRGA
vi) flashed through Odin(AP,BL,CP,CSC)
vii) Phone completely formatted and boots up.
"Error:Invalid SIM card inserted. Network Locked SIM card detected "
I am now being asked for PUK code or cellular service wont work
You need to contact your carrier for PUK code, its protective measure against too many wrong PIN attempts on specific SIM. Can't fix that with any flashing.

This is where the problem is. You put any sim card in that phone, you get the same error. The sim card works fine if I put in any other phone. I am not sure but unistalling Magisk has caused "SIM Card Read Error" in my S9+. I even upgraded to Pie from Oreo and flashed 3 different stock firmwares but the sim card error exists.
@topjohnwu
I would appreciate if you can help me on this. Not sure how to fix the issue
Looking up the error message itself points to some sort of network/carrier lock. If I am reading regional lock and carrier lock definitions correctly the two are not the same..
Did you have the phone network unlocked or was it network unlocked when you had root installed? If the device was network unlocked when it was rooted and you flashed back to stock (which removes root) this might explain what is going on...

This is an unlocked phone. I had magisk installed and when trying to uninstall it to upgrade to latest magisk, the device wont boot except download mode. So, I downloaded stock firmware and flashed it. Once I boot up with the new stock firmware, I get this error
There is some sort of lock on the phone, which is why your being asked for the code.
I think you should definetly try was what was suggested above.. trying to contact the carrier and see if they can give you the PUK code. If I recall correctly you get a few tries to enter it correctly before it won't let you anymore (and it might lock the phone up good or damage the sim)
I'm having a similar issue on a Verizon A50. Any progress?

depending on what method was used to unlock it, its likely no longer unlocked. some sellers of unlock codes neglect to mention that part. im betting its locked again
