Can't write sim unlock code, please Help - Samsung Galaxy S8 Questions and Answers

Hi.
I bought a locked s8+ from Telcel México. I want it to use it on Att, I have the unlock aim code. The problem is when I instert the att sim I got a message "SIM network PIN blocked. Enter Sim network PUK." and a small lock blue icon. But I can't write anything, there is no keyboard option or anything. Any help? Thanks!

Have you tried another SIM card? Maybe read this: https://www.att.com/esupport/article.html#!/wireless/KM1000485

I just unlocked my phone this weekend. A number pad should have appeared. If you didn't turn off the phone to change the SIM try restarting. If that doesn't work try a different card.

Tried 2 different cards and had the same screen.
Now I flashed a new rom, that screen disappeared but now when I insert a new sim car got a new screen and now I can write the numbers. The problem is that I don't have the PUK code, I think that I need an unfreeze code, anyone knows how can i get that code? Or how can i unlock my phone?
Thank you!

Same **** with mine.

I got S8+ from f#c!¢n Telcel and paid for the Network Unlock code and have the same screen with the blue icon and cant do **** about it. With the new ROM ( Which one did you flash ) did you have any luck, have you unlocked your phone ?

You need the PUK code for the new sim card - most print this on the card that you popped the sim out of. If you don't have the original outer card, then call the carrier for the NEW sim card you are trying to use and they should be able to help you.

Unlocking G1 without an Different SIM Card

Hello everyone,
I'm trying to find out how to SIM unlock my G1 without having an AT&T sim card. I have an unregistered T-Mobile sim card available if it could be used at all.
I tried searching but I must be using the wrong search terms because I keep getting results about unlocking using an AT&T sim card to get the request for unlock code to show up.
I have the unlock code, just need to be able to enter it.
dunno if its the same as the UK but I unlocked mine the other day from T-Mobile with an unlock code and all i had to do was to put the wrong sim card in there (i.e. the one u want to use) and then it should prompt you for an unlock code....
Yup, just shove in the ATT SIM card and it will ask for your code...

code doesn't work

Hi,
I recently purchased a unlock code from unlockadic for my vibrant but when I went to use it it said Network lock request unsuccessful. Does anyone have any ideas?
If this is in the wrong section I apologize
P.S. I did contact unlockadic and said that this has never happened and that he would have to have his guys look at the problem.
bump because i had the same issue.
you need a non-t-mob sim in the phone for the unlock to activate
I have an account with Rogers & that is the SIM l put in the phone-result was unsuccessful. Code is correct unlock code-i got the same code from three different sources but no luck.

hussafilms is correct.
You need to put in a sim from a network that the phone was not designed for. So if you bought the phone from tmobile then put in a att sim or if you bought it from another company put in a sim that is not from that company. So if you have the galaxy s from rogers then put in a tmobile sim or something.
Let me clarify, I bought a Samsung t959 Vibrant from ebay locked to t mobile and I put in my Rogers SIM card, entered the code and it was unsucessful
How many times did you try to enter the unlock code? I beleive if you have three failed attempts, it will be permanatly locked.

[Q] No SIM or Invalid Sim Card Error....Please Help!

Hey guys
So I just got my LG Quantum off ebay. I put my Rogers sim card in and I boot, it tells me it cant recognize that there is a sim card or it is invalid. Im not sure what to do. I am switching from a Samsung Focus so there shouldnt be a problem. Yes the phone is unlocked, well the seller said it was unlocked but I wont know until it recognizes a sim card. Any help or ideas out there?
Anyone? bump

Sorry, I only check in every couple of days.
Sounds like your phone needs to be SIM unlocked. (I.e. the previous owner simply sold you a phone which is 'locked' to another vendor's network like AT&T for instance).
What you need to do is go to eBay or google for "LG Quantum Unlock Code". You'll need the IMEI (inside the battery compartment) and it shouldn't cost more than about $20.
Well the thing is the seller sold it unlocked. But Im skeptical, so I bought a code and such from cell unlocker, but the issue is that it doesn't recognize that there is a sim card inside of it. I have tried 2 bell sim cards, and 2 rogers sim cards. This is the problem because with the quantum there is no way to unlock it that I know of that doesnt require a sim card. It hasnt recognized any of the sim cards, it boots up and sais that there is no sim in the phone.

That's weird, it should at least prompt for PIN, PUK or unlock code. I would try:
1. Reflashing and then try if it asks for unlock code
http://forum.xda-developers.com/showthread.php?t=935605
2. Rebel Sim II 30$ (SIM card chipping)
3. Octopus India, 83$ (Unlock/repair tool)
My Quantum in is "PUK-code-loop" and unlocking code, reflashing or correct PUK wont help.. Rebel SIM II is on way..
I finally managed to unlock using Rebel SIM II:

There was no need to purchase the code as there are several threads here on how to menu unlock it. But since we are beyond that, I'm guessing the other SIM is not provisioned and has no service on it. Try using a friends T-mobile SIM. That's how I was able to check the menu unlock method.

Thank you for your answer.
I used a regular size Vodafone SIM which I just used in Europe last month, on my other phone, so that SIM should be ok.
However I used a SIM cutter to transform in into a microSIM . Visually looks ok too. Could it be that in this process the SIM (now microSIM) got damaged somehow?
When I first insert it, I was prompted for the unlock code, which I typed, got an ok message, but that's about it.
Now says "emergency calls only" and it does NOT prompt me for the unlock code anymore.
Original ATT SIM works just fine.
There's more: I just put that Vodafone microSIM into my wife's phone (which is unlocked) and it works fine.
So bottom line, I used an unlock code which apparently worked (got the message "network unlock successful") but the phone does not appear to be unlocked.
I will definitely try a T-mobile SIM as soon as I find one, but in the meantime which is that "secret code" to check network status for this phone?
*#7465625# does not work and returns "connection problem or invalid MMI code"
Thank you
anybody has the answer to my question ?

Simunlock Problems

Hey there,
I got a I9505 that doesn't detect my simcard (if i put it in it still say pls insert simcard like there is none). so my guess was carrierlocked...
It also doesn't ask for an networkunlock code .. so i didn't wanted to buy a code on these websides because i didn't know where to enter the code.
Well I've tried the trick with the *#0011# and it doesn't go into the Service Menu.
The phone is on 5.0.1 could this be the problem ? Is there a way to downgrade?
Or do i have to falsh the modem in any way?
Till now i've just changed the FW with Odin to the DTB Version.
I'm kind of scared to try other things if I'm not sure what they do...
I'm really sorry if the solution is in a thread i havend found or just overlooked
thanks for your time and help
A properly working SIM lock would recognize the presence of the SIM card, and when you unlocked the phone, would prompt you to enter the unlock code. Therefore, a carrier lock is not the source of your problem. Unfortunately, yours is a hardware problem, and based upon your description, it's a motherboard failure, rather than a SIM card tray failure. It cannot be the SIM card tray because a SIM card tray failure would not ask you to insert the SIM. Instead you would have a circle with slash in the notification bar to the right.

Thank You for your help,
So in the mean time I successful downgraded to 4.4.2 (cyagogen)(and upgraded again) found a soulution to flash and access the modem so i could do the trick with *#0011#...but it's still not working.
I just don't to belive that its a hardware problem. Is there anyway of another software Simlock?
Because the Network Conectivity bar is showing 3 bars.
I got it (not so) cheap from ebay, so could it be that the imei is block in the network ?
Thanks agian for your help
IMEI could definitely be the cause of your problem, especially if you actually do have a signal.
It is showing 3bars but not the H for HSDPA but it also shows those bars if no sim is insert so...
The imei ist blocked ?
Guess there is no way to change it

If no SIM card is inserted you wouldn't have any signal, but a missing SIM card indicator. This behavior confirms to me that you have a hardware problem of some sort. You need to have the device looked at, because software is unlikely to be the source of the problem.
