Dumb Question About SIM Unlock - HTC Startrek

Hi
I just bought a Cingular 3125 on Ebay, and according to the seller the phone was SIM Locked.
So I assumed it was Sim Locked and meanwhile I receive the phone I started looking around for different ways to Unlock it, so when I finally received my phone, I inserted my SIM Card and worked fine! so my questions are:
After all of the events, can I say that my phone is SIM Unlocked?
Is it possible that my local Carrier (Telefonica) has the same configuration as Cingular so the SIM Unlock Code was not required?
Thanks for your help and your expertise.
Best Regards

If your SIM worked I'd say it was SIM UNlocked AFAIK no SIM from another carrier will work if it's SIM locked. A simple way to check would be to try another SIM!

If I understand correctly, there are actually different levels of sim locked. Hey may have just been locked out of his own sim which can happen if you try the wrong code a few times. That way another sim might be able to work on that phone. I am not sure since the wireless carriers that I worked for never used Sim cards.

UPDATE
I just checked with my wife who works for ATT and she stated that it is possible for people to lock themselves out of thier SIM cards and not the phone. Should the person lock themselves out of the phone and SIM then they are kind of SOL unless they have great friends like the people at XDA or can get the manufacture to give them the lock code.

[Q] Hero blocked from making calls

I tried to get my phone unlocked today, however ever since then my phone hasn't been able to connect to any networks. I had to give my Imei number to get in unlocked, is there some way this could have been used to block my phone?

Yes in theory it could. Try the old sim and see if it works.
To block an imei requires access to the network systems, although you could phone them up and perhaps maliciously block an imei.
Did you use a reputable unlocker?
I used one off ebay however they had 15000 positive feedback.
I rang T-mobile and they say my phone is not blacklisted but its also not been unlocked. I dont know if this is true as when I put my unlock code in it said unlock ok and now when I put another network sim in it doesnt ask for the code. Ive since tried to use an orange sim card in it and this works but I dont know if this is anything to do with the fact that Orange and T-mobile have merged.
If it isnt unlocked then i dont know where to put a new unlock code in.

Lol you are fine.
Tmobile don't know it is unlocked. It worked fine if the sim doesn't ask for the code now.
If an orange sim works then phone is OK. What is original problem again?
Lol sorry I havent been very clear.
Ive bought a Tesco mobile sim and that is what I want to use however when I try this sim it wont connect to the network. Ive also tried a O2 sim with the same result however an Orange sim does work
I really have no idea what could be causing it and ringing Tesco/T-mobile has been no help at all lol.
Might be a stupid question but are you sure you can get Tesco Mobile signal? Both Tesco Mobile and o2 use the o2 network. So that's probably worth checking.

Ive tried it in my girlfriends iphone and it works perfectly so I cant imagine its the signal. I'm totally flummoxed, the only thing I can think of is if the phone isnt unlocked, but then why then does the orange sim card work?
OK I've come to the conclusion that it hasn't been unlocked and the reason the Orange sim card works is something to do with their networks being joined. If this is the case is there a way of re-entering the sim unlock code?
TMOBILE has blocked your sim, you may need to root

TMOBILE has blocked your sim, you may need to root. My experience is this: I have a rooted HTC that works fine, however when I put the sim in my S2 or a second T-Mobile phone I get the error message "cannot connect to network" even though I have 5 bars.

[Q] Is it possible to remove network lock without an unlock code?

I have reviewed similar threads for a few days but have not found any answers. The simple question I have is in the title:
Can you unlock the ATT Atrix without an unlock code.
However the situation is a bit more complicated and ill explain.
I have been traveling the past few months and was in Costa Rica for a month. I decided to purchase a local SIM so I could use my phone without paying ridiculous ATT roaming charges. I inserted the SIM and it was locked, unaware of the network lock I inserted my personal code thinking that may be it. No luck and returned to my old ATT SIM. At this point it still worked but a few days passed and I tried again, still no avail so I contacted ATT. It just so happened the 6 month mark was coming up from the original purchase date of my phone so they would provide the unlock code in 4 days time. I waited and finally received, after inserting the code it did not work and I contacted ATT back to assure they provided the proper code as they had to send me a replacement phone a few months prior due to my original Atrix crapping out. They checked it out and determined it was correct but it never worked. I finally inserted my original ATT SIM back into the phone and it also requested network unlock code. Now I am back in the states and even with the original ATT SIM it still requests for the network unlock code. I tried unlocking and flashing with CM7 beta and STILL requests unlock code. So basically the phone is useless for network data but will work fine as a mini tablet i suppose connected to WIFI.
So with that explanation does anyone have any idea on bypassing this or removing this entirely, not even to use overseas but just on the ATT network!
Additionally
ATT provided me with another Atrix to alleviate my troubles so im not entirely phoneless. However I would like to sell one of these and possibly purchase the GS2 0_o
I have contacted 3 cell phone unlocking sites explaining the situation and only one has responded but not with any answers.
HELP!
if you got a new phone, is it still asking for a network unlock code?
No. Its working fine, but I still have this perfectly good working phone I would rather use and sell the brand new one. Unless I cant get rid of this unlock problem I suppose Ill sell it as is. Any takers?
Hi, I talk to att once when i want to unlock my atrix and they told me if the phone is more than six months old the give you the unlock code for free.
so for the atrix if that is your phone you can ask att for your code since august 21.
just call att customer support.
hope this help.
try a diff sim card with data plan and see if it still asks for code
or try flashing a custom rom
I suppose I was not clear in the OP. ATT DID provide this code for me. I did flash a custom rom already.
As far as using a different SIM card I tried to use a second SIM that ATT provided and still nothing.
I am assuming this is a very unique situation and probably wont find any answers unless someone has successfully unlocked the phone by flashing some special ROM.
Flashing a ROM of any kind will never sim-unlock your phone.... ever. period.
The only way to resolve this is through AT&T. The only way to sim-unlock is with the code it requests.... must have proper code. That is the only way. So, I would talk to AT&T about it, in person, at a local store.
I unlocked the inspire 4G simple by rooting and flashing a custom rom didnt ask for network password after that it worked on tmobile
With edge service no. 3g or 4g different bands between tmobile and att

Just the info I was looking for. Basically the phone is boned in that case. Spent a good with with ATT advanced tech support and motorola to no avail.
What I do want to know is WHERE this information is stored out of curiosity. It seems the modding community would have tinkered with some hacks to remove the sim lock at some point.

Tried to screen shot it but it wont allow in the screen. The request comes as soon as I turn the phone on. If I dismiss it I can use the phone I just wont have cellular access.
Ok so I am reposting and not editing as I feel this deserves a bump.
I got my new Atrix unlock code from ATT today and tried it on the new Atrix I received and that one ALSO will not unlock.
Is there ANY ATT Atrix sim unlocked and if so how did you go about doing it? I have only found one thread and no response via PM.
How to SIM unlock Atrix!
I have read both your post and I believe you used a ATT sim card that was not in use or a GO phone Sim card. Am I correct so far? To sim unlock you have to insert a non ATT sim card!! No go phone sim card or a non active att sim!
Call one of your friends and borrow a Verizon sim or Tmobile sim. You only have 5 tries to do this. So as for your first Atrix I believe it is already locked permanently to ATT. Dont ruin your second Atrix.

Well I found that if you push #073887* in the dialer it will actually prompt you for the unlock code. I tried this with NO sim in at first and that is when it said it was unsuccessful. However late last night I inserted my ATT SIM back in and tried again just for ****s. Entered in #073887* and typed the unlock code and viola, it worked. Interesting information for anyone who wants to unlock there Atrix WITHOUT another carriers SIM!
But back to my original issue. I wouldn't mind if the original atrix was locked to ATT, at least I would still be able to use it. The problem is that it wont work with ANY SIM. My thoughts is that it is a glitch and locked the phone to... nothing?
To make matters worse I emailed cellunlocker.net explained the issue and they said they thought if they requested a carrier unlock code it would work. Paid the 20 and 10 minutes later they sent me the same unlock code ATT had provided. Now the hassle of obtaining a refund.
are you selling the phone?

Yea. Both.
you have to use a *different* sim card than your regular carrier uses (ex - I'm on AT&T, so i used a Boost Mobile Sim to unlock my Atrix) You cannot use YOUR sim to sim-unlock.

Yes you can, by the method I explained in my previous post. It works!
There may be some confusion. The one im referring to (the original ATRIX) will not unlock with an ATT sim, a TMOB sim, a verizon SIM, or even a Costa Rican SIM. NO matter WHAT the SIM is in the "original" phone it always prompts me for a SIM unlock password. Like I said I believe it to be a glitch, intending to lock it to the ATT SIM but in reality it locked it to NO SIM.
So to restate.
YES you can unlock an ATT Atrix with only an ATT SIM in the phone using the method I explained. ( I did it with the phone in my hand right now)
and
NO my original Atrix will not unlock regardless of SIM installed or method.
i will send you a p.m with my offer
Just out of curiousity did you ever set up the sim card lock feature in the location and security settings. It will ask you for the unlock code every time you turn your phone on...shot in the dark here....

Atrix 4G unlocking SIM

I'm getting a bit frustrated... I have unlocked and rooted the phone and now I"m trying to unlock the SIM so that I can give it to my wife to use with a European Sim Card. I've googled, read and read and so far I've done the following:
1. Placed the European SIM into the phone (that I used in my old TMobile phone to date)
2. Was presented with "Enter sim network unlock pin"
3. Called AT&T and obtained the "unlock code".
I tried that code 3 times so far. After spending a fair amount of time with ATT support on the phone they believe that the "pin" is different from the "code". Btw, the unlock number was confirmed to me by ATT support folks twice... I rechecked the IMEI number twice... and I"m stuck... what do I do? Is there a difference?
Btw, I tried it under CM7 and AOKP
Thanks
SIM vs Carrier Unlock
There is definitely a difference between Carrier unlocking and SIM unlocking. I was steered wrong by AT&T the first time I asked. Essentially, they gave me a code that would allow me to override being locked out of my SIM card (to access phone numbers, etc) as a result of entering the SIM password wrong. This was NOT what I wanted.
I called back, and specifically requested a Carrier Unlock (for using other companies' SIMs), and they then made good on this request. You will need an active SIM from another carrier to get the job done, but if you specify your request to them, hopefully they will get it together. Another option is to buy a code at the numerous online re-sellers, but like I said, AT&T gave me mine for no cost. Good luck to you!

Thanks, unfortunately they keep sticking by their guns and claiming that the code they're providing me with is the proper one.....
Don't try too many times, after maybe 5, not sure, you can permanently lock your phone. It is a security measure.
You nay already know, but hate for you to mess up your phone.
I'm still convinced that there's no way AT&T or anyone else would be able to tell you remotely what the code is.
When you buy new SIMs, they come inside a credit card-shaped piece of plastic. On that card itself (not the sim), there's two spots: one for a PIN and one for a PUK. The PIN is needed because the new SIM defaults to being locked as a security feature. Every time you turn off the phone, the SIM locks itself. Once unlocked, however, you can go into a phone's SIM settings and leave it unlocked permanently for any phone.
You need to find the card that originally came with the SIM.
Chrism suggested not to attempt the wrong pin too many times. It won't lock your phone, it will lock the sim and then require you to enter the PUK code.
I still wonder if it is the phone. When you enter the code, then you can use any sim card. He wants to unlock the phone to work with a different carriers sim I believe.
His problem is with the phone, not with the sim, is it?
Could be wrong.

I believe this is correct. Also, if you are entering the carrier code, and enter it wrong a specified number of times,i'm pretty sure it can lock your phone. I have unlocked well over a dozen, and have always been warned about it....

Reread the OP. The phone is already unlocked and rooted. That means that technically yes, he can use any sim card on his phone.
However, not all sims are sold unlocked. As I mentioned before, it's not uncommon to buy a prepaid sim outside of the US (like the OP's Euro sim) and be asked to enter the sim pin upon start up.
If you reread the OP, you'll see that he's describing exactly what I'm talking about. I've had to do this a handful of times on a handful of unlocked phones.
Regarding locking the device, again, the OP phone is already unlocked so locking the actual phone due to entering the incorrect pin is impossible. It would be the sim that would be locked (since the phone is asking for the sim pin) and could only be restored by entering the PUK. I've had to do this a couple of times myself for people who had forgotten their sim pin but still had their original card info at home. Once you enter the PUK, it works again.
i would Spend the 20 or 30 buck online and get a diifferent code

Regarding post #8
I agree with post #9 as well.
Maybe so, not my experience though. He has unlocked the bootloader and rooted. He has not carrier unlocked. I don't think that they are the same, but you could very well be right. Thanks. At least we are all trying to help him out.
That sim seems to already be unlocked if he has been using it in a T-Mobile phone to date. His ATRIX is still network locked.
OP. Let us know please. Now I am curious.
Thanks.

I still haven't read where the OP stated he unlocked the bootloader. Rooted, yes. When I read "unlocked," I take that as "Carrier unlocked" the way that googling "unlocked cell phone" would bring up unrestricted/debranded/etc. cell phones, not necessarily having anything to do with the status of the bootloader.
That said, the bit about him using the sim on his older tmobile phone made me assume one of two things: he either forgot the code he used for that phone or it's a bad sim.
Granted, not every carrier unlock code works but given that he was getting it directly from AT&T (and it was on their servers), it should work. My Atrix, for example, required a code off Motorola's servers and even then the first code worked perfectly.
Trust me, if the OP has gone through all this trouble and the only thing left is to try the SIM pin then... 1+1=?
With the ATRIX you usually unlock the bootloader first, but that would explain some confusion.
Hey, I'm not trying to argue or anything.
OP, what unlock did you perform?
This thread is seriously non reality based.
Neither rooting nor unlocking has anything to do with getting the subsidy unlock code that allows non-ATT sims to be used.
ATT can cerrtainly provide the vaild code, and has always done so for me (albeit after possibly a await time).
3rd parties MIGHT be able to provide the same code. YMWV.
There have been some reports (search) that with the wrong radio the unlock code does not take. So ithat might be a way to go.
Wow, we are going round and round. Good luck.
Use search!!

Try THIS Thread---->Solved: Sim Unlock Fails With Valid Code
Sorry for taking so long to reply but for whatever reason I missed the email saying that there are replies. Anyways, lets recap
Phone is rooted and unlocked. I can run any ROM that I want and bootloader is unlocked.
The sim cards I am testing on (yes, plural) are not locked (as in they do not require a code).
I am trying to use a non ATT sim card (specifically I am trying TMobile EU) so that when I go traveling to EU again I can use the ATRIX with my local number that I keep rather then the ancient HTC windows phone that I have used to date....
I have made 4 attempts at unlocking so that means I am down to last one.....

[Q] Technichal Question Here

Hey everyone. Recently I did the free sim unlock that crixley posted. Now I checked the phone to see if it was unlocked by entering the special code on the dial pad. I followed the instructions carefully but nevertheless - my i717 kept saying "No SIM Card" whenever I put in the tmobile sim but it read my att sim when I put it in. Now i tried different modems/radios but still the same thing. Im not sure if its a problem with the sim because it is old. It came with my HTC Sensation 4g from tmobile and that was about early 2012. The sim has just been in a box with stuff all over it to so I dont know if its ruined. What do you guys think? Ill post a pic of both sims. Ill post a pic of unlock message to. Thanks!
Top Is Tmobile sim

You unlocked the phone -- why? You don't have an account with a non-at&t carrier?
Just borrow a non-at&t sim card from anyone.

Verizon S9+ sim locked?

Does anyone know if verizon S9+s are sim locked?
I am planning on travelling europe/asia for the next month or so and wanted to buy some local SIM cards... will that be a problem?
Can't say for sure because I went with the unlocked version, but that was due to Verizon indicating that their LTE phones would no longer be unlocked. They decided to flip the FCC the bird and start locking phones because they knew that weasel Ajit Pai wouldn't try and enforce the deal Verizon made to get some of their LTE spectrum. Unless someone has actually tested this, I don't know if there will be a definitive answer out of Verizon.
It's funny how Verizon does this. Phones are unlocked. If upon first boot, no Verizon Sim is detected the phone will remain unlocked. If a Verizon SIM is detected they will lock the phone and you need to request a unlocking code from them. Their policy is to not provide a unlocking code until the phone is paid off but I heard of them giving that code out for long time customers.
I tested this theory on a friend's phone. Booted the first time without Sim and the phone is unlocked now.

Never heard of this. I tested many Verizon phones, all unlocked. Recently it was announced that they'll be locking phones, I am curious if the S9 was plagued by this BS. Before they announced they'd lock the phones, there wasn't any issues with using it on a different carrier, unless it was a prepaid Verizon phone.
Just check it now by inserting another sim card in your phone to see if it will pick up the signal or if it's locked.
Any sim will do because if your S9+ can't recognize another US sim card will not recognize either a foreign one.
