Hi,
I have bought HTC Desire (New) from eBay and seller said that he got it from T-Mobile and he don't know if it is unlocked or not. The thing is that from all topics I went throught it always says that if my phone is locked and I put different sim there then I will be prompted at boot to put code. I have tried with different sims (Vodafone, o2) but I have no such code input. Now I am using T-Mobile some cheap card and everything works but when using another card it gives me LIMITED Service Warning and no signal. It cannot register to any network as well. Any ideas if I should go and try to unlock it via some codes or it is unlocked already but I have to rebrand it?
Thank You,
Golotap
I was at Police/Vodafone/T-Mobile/T-Mobile/Another T-Mobile and everyone says this phone has been blacklisted in UK this is why it has such problem ._. so now I am just sending it back to Ebay seller.
Thank You,
Golotap
The amount of people buying from eBay and having problems is unreal. Go buy it from a retailer sicne your guaranteed it actually works.
The problem is money, normal phones are just too expensive for me so many people are just going to eBay.

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
I recent bought a Arc S from someone on kijiji (according to him, this phone is locked to Canada rogers), and when I started the phone, it shows the Rogers logo as well.
the problem is, this phone does not work with rogers sim card, it displays
“This sim card cannot register with this network”, if I insert others like bell or telus, it will request a unlock code.
first, I went to rogers store, they found out this phone warrenty expires at June 28th of 2013, which is wierd, then they told me they could not fix it because I didnt buy it from rogers store.
So I bought one unlock code from "cellunlocker.net" and trying to use it on another network, however it failed again, told me code is wrong!
I have contacted with "cellunlocker.net" about this, they insist this is right code and can not do anything about it
what can I do now?
can anyone give me an advice before I throw it away or sell it as defect phone?
thanx
Unlocked phone locked after one year with "Network locked SIM card inserted"
I purchased new unlocked Galaxy Alpha on eBay about a year ago. The phone worked fine this whole time and suddenly after a short outage of my mobile network it got kicked out with "Network locked SIM card inserted" message.
My operator checked the SIM is OK with other phone and gave a me couple of codes which didn't work so they told me they can't fix it.
I tried to buy unlock code on several Web sites but couldn't find someone supporting Galaxy Alpha with Israel Pelephone provider.
How is it even possible for the phone to lock after being unlocked for such a long period of time? What sites can you recommend for getting unlock codes?
Thanks.
I have a supposed 'unlocked' pixel from ebay, sealed in the box. A warranty replacement that was never used. While trying to turn on OEM Unlocking, it is greyed out and says "Unavailable on carrier-locked devices." I've tried everything I can think of or find online but it remains greyed out. It's updated to android 11. Unless someone has some advice here I'm going to have to sell this device as it is useless to me.
I only wanted it if I could unlock the bootloader which it seems I cannot.
What disclosures should I make to anyone wanting to purchase this device? Is it SIM locked or just OEM locked? Can this be used with any carrier as far as normal phone usage? I have put the IMEI into Ting and US Mobiles device checkers and they come back reporting the phone is ready to be used but I don't know how accurate that is. Could the previous owner still have the device listed in their account somewhere (Verizon or Google) which renders the phone unusable?
Does this only work on the Pixel 3? I couldn't find any similar option for the Pixel 3a XL posted.
Code:
From https://joshspicer.com/root-pixel-1
Open terminal in adb directory and type adb shell pm uninstall --user 0 com.android.phone
Thanks for any advice you can offer me.
As far as I know there is no way to unlock a Verizon 3axl. If it was Google then it would not have the option greyed out. The person who sold it to you may have meant carrier unlocked.
It was actually Sprint. The seller contacted Sprint and said they would unlock it. Somehow they are going to do it without me having to send it to them. So, that seems like just a SIM unlock to me? I've never had to have one unlocked before. I will report back afterwards. I had to download a virtual SIM to first activate it on Sprint's network. Anyone else go through this with Sprint?
From now on, if I want to purchase a phone off eBay I'm going to have to get the seller to show me the unlock option. That's not going to be easy as most sellers won't know how.

Once you get it sim unlocked you should be able to toggle oem unlocking. I had to get my TMO sim unlocked before I could oem unlock as the option was greyed out like yours.
You have to have the SIM card unlocked before the phone will let you OEM Bootloader unlock it.
This is to protect the wireless providers because if you could OEM bootloader unlock it even if it was SIM card unlocked, you would have an avenue to then unlock the SIM card lock.
Once the SIM Card is unlocked, then the OEM Bootloader option should be available (Verizon being the lone exception to the rule, but I believe there are work arounds to unlock the Verizon models after they are SIM Card unlocked).
To follow up, the SIM card unlock came through in just a couple of days. This was fortunate that the seller was willing to put the phone back on their plan in order to unlock it, others may not be able to do so; depending on how they purchased their used phone. Just be careful. You may have to sign up for the carrier and have the phone unlocked yourself. The OEM unlock toggle worked like magic. The phone is now sporting graphenOS and rocking and rolling forever free.
Thank you everyone for sharing your knowledge.
Sharing my story. Bought a used one listed refurbished on ebay for Sprint. Activated fine on my sprint account and I chatted in and asked to unlock it and they told me I had to wait 50 days. I waited 50 days chatted back they sent the unlock code and worked instantly. Running lineage now.
