complete noob, just bought a second hand galaxy s

please point me in the right direction
my sim card does not work, how can i unlock the phone to all networks? i hear theres a diy tutorial. im still on android 2.1

There's an SGS Unlock Tool App is in the Market. Search and Use that.
If it works, you'll get 2 set of codes. Unlock Code and Unfreeze code. save this somewhere like your PC or notebook. Don't lose these codes okay?
Now insert your sim again and it will then ask for the unlock code, enter it and bingo!
the unfreeze code is used when your phone freezes if you try entering invalid unlock codes several times.
Hope this helps.

thanks, i'll try this when i get home
should i update to froyo 1st?

nope. try the app while you are still in eclair. the app has some issues with froyo (i think) so better unlock it while in eclair before you upgrade your firmware.
let me know what happens.

wouldn't flashing it with a custom rom remove the internal branding and limitations?

Maybe but based from what happened to me in eclair, it did not remove the sim lock.

Yes, 0's means your phone is already unlocked.
Will be something either wrong with your Sim card, or the phone has been blocked by the networks

well i tried my friends sim (he on another network from me) and that worked, maybe my sim card is old?

So your friend's sim on a another network worked?
Either your sim is bad or your network blocked the phones IMEI.

SIM card issue

Hello SG3 owners and colleagues by phone device
I am new to the forums but I am a long time advanced Android and SG3 user. I have tested almost all ROMs available in the SG3 and X8 sections.
I have a serious issue with my SIM card that I use with my SG3. It worked fine since I got the SG3 and it worked with all ROMs. Yesterday I wanted to flash a stable Eclair ROM and settle with it but this is when my issues started.
I flashed the Revival ROM Classico. When I booted into the OS I was asked for the SIM PIN. I know I have turned this off, but I imputed the last PIN I used. I got an error, service denied (or something similar) and I could not get past this prompt. When I dismissed the prompt I got into the OS but I had no network. OK, the rom clearly sucks and I reflashed CM7.2 A8 which I used normally since it was released.
CM7 was not asking for the PIN, but I had no service in this ROM either. Did factory reset, reflashed, nothing, tried CM9, nothing, tried MIUI nothing.
And here is the weird part...when I insert another SIM the network on the SG3 works fine and I get service. When I insert my current SIm (that does not work with SG3) in another phone it works flawlessly :/, so only when I use my current SIM with SG3 no matter the ROM I get no service.
Anyone can help me?! Should I damn the Revival ROM dev to eternal suffering? J/K

Check your imei first

I found out what the problem is, my phone is now network locked and since I use different operator than the phone default locked operator my SIM can't get service. I can't net unlock my phone with ADB, tried nv_data.bin and bml3 extraction but there is no code there.
This ROM is to blame!

DO NOT FLASH THIS ROM! This stupid f*ck should be ass raped, he now asks $25 on youtube to unlock my phone!

SIM problem
I have a similar problem with CM9
I have my SIM locked with a PIN but CM9 does not ask for it, ever.
I tried to select my network manually, but a get "network is not available"
The only solution I found is to disable the SIM lock although I don't like it much...

its not the same problem, sim lock just hasnt been added to the function list on CM9 yet. Im not sure it will be added either as i dont think its on official cm9.

[Q] SIMs unreadable

Hi guys! A friend of mine got this strange and unexpected problem!
He was using the Cyanogen 7.2 stable and he screwed a little bit (don't know how really exactly) so I wiped his phone and reflashed the ROM 'cause it rocks
Before that he told me that after turned off the phone, he removed the SIM card (don't know why) and after he re-insert it and turned the phone on, the phone is no more capable to read any SIM card!
How do u suggest to proceed? I don't care what was the cause of this! I exclude a virus, at least there're free app virus-embedded in the play store!
Anyway I'd like to solve this ... what do u suggest?
Thanks in advance!

Reinstall and leave the SIM in the phone?

If you have not tried different SIM, then try to test the phone with a different SIM to see if the problem still exist. If no problem, then he needs a new SIM.

Attempt to reflash the radio on the N1, it could help to solve your issues

Then consider your N1 as a tablet, a very, very small tablet . Or you could send it into repair with HTC and get the motherboard changed

S4 does not recognize my sim card

Hello guys,
I have a rooted S4 with Knox Flag and a custom rom which really worked well. But now i do not understand why i am getting a pop up which says that the phone can not recognize my sim card and wants to restart. First it just came some times. Now it totally does not find my sim card. I also bought a new card reader and built it in but i have the same problem.
I also tried to bring everything to Stock but this either doesn't worked.
I hope someone can help.
Thanks,
Musti

Reflash STOCK ROM and tell me if works ok. Looks like a hardware problem anyway.

Things you can do.
-Flash stock again.
OR
Update your modem.
maybe its hardware related. go to phone repair shops if they can help you.

Hey,
so I flashed the stock rom via Odin but it is still the same problem.
What do you mean with updating the modem? Maybe I should read and try that out thanks!

Hi mate ,
The problem may be in the EFS partition , do you have an EFS back up? if not you may have to take it to a local service shop , you need a Z3X box or similar to fix it.

Whats your model number? Go into the phone settings and check in there. The more details you provide the faster you will get an answer. Going through the Odin process you mentioned will not unlock your phone. It lets you change to different carrier firmware but you still need an unlocked device otherwise it will not work.

Strangely I cannot find anything on that model # you posted. Are you sure; there is F after GM950? Can you go to Samsung official website > http://www.samsung.com/us/mobile/phones/galaxy-s/s/_/n-10+11+hv1rp+zq1xa/ and find your model? Also, can you also share your baseband version as well?
Edit: Looks like you have the Exynos model which goes by different alias (SM-G950G, G950G, SM-G959FD, G950FD)? Is that correct? .

This happened to me earlier today also. I have the G955F since late May and all has been well. I wanted to Flash CarHDRom V.4.1.1 today coming from Renovate. First boot with new rom I get the unlock sim screen. (never seen this after almost 8 years of flashing) Also a standing message in notifications "network locked sim card".
The sim card works fine in my backup phone. Why would it all of a sudden do this and how do I find the unlock code? Phone is otherwise useless now.
