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.

I think you should start from the beginning. Where did you get the phone from? If you bought it from T-Mobile, you should be able to just call them and have them unblock the phone.

[Q] Galaxy S4 (SGH-I337M) says NO MOBILE NETWORK (HELP!)

Hey guys,
I'm new to the forum so please excuse me if this is the wrong place to post this. I'll start from the beginning. I bought a Galaxy S4 (SGH-I337m) from somebody in my city. They said the phone originally worked with Rogers/Fido, but that they switched the logic board on it so now it works with Bell/Virgin. The thing is though, when I put my Virgin Mobile sim card in the phone, it won't let me send texts or make calls. I checked the IMEI and it's not blacklisted or anything.
It says No Service and has the little circle with a diagonal line showing up in the notification bar and when I try to send a text, it says No Network Connection (No signal found for mobile networks). I find it weird because I still get a notification saying that I have an unheard voicemail.
I've tried resetting the phone multiple times. I've also tried flashing both the Bell and Virgin Mobile Lollipop firmwares and that didn't work either. To be honest, I'm not sure how to tell which one I would need to install. I noticed when trying to flash the Bell firmware, that the phone kinda skips to a black screen quickly every time I close an app. I'm assuming that would mean it needs the Virgin Mobile firmware.
That still doesn't fix the mobile network issue though. If anyone could help me out, I would GREATLY appreciate it!!!! Here is a bit of info, I'm hoping it helps. If you need anything else, please let me know.
Model number: SGH-I337M
Android Version: 5.0.1
Baseband Version: I337MVLUGOC4
Build Number: LRX22C.I337MVLUGOC4
Also, in the "Status" menu, I noticed it says:
Service State
Voice: Out of Service / Data: Out of Service
Not sure if that has anything to do with it or if that's normal. Again, if you have any suggestions, PLEASE let me know. I'm super desperate as I can't afford to lose the money I paid for this. Thanks in advance.
EDIT: Coincidentally my girlfriend has a Galaxy S4 of the same model and with Bell/Virgin. I opened up the ABOUT DEVICE menu in both phones and the only other difference I noticed is on hers it says:
SE for Android Status:
"sepf_sgh-I337M_5.0.1_0013"
And mine says "sepf_sgh-I337M_5.0.1_0009"
Does that have anything to do with it maybe?

Install this APP and add all screenshots pls .

Okay, will do. I will post the screenshots in about 20 mins. I rooted the phone, installed CWM and am in the middle of flashing the latest firmware again. I forgot to enable USB debugging before flashing originally and I wanted to install CWM to wipe the cache. No idea if that would make a difference but I've been up all night trying anything lol. Thank you for the reply though, will post the screenshots in about 20 mins.

Okay, I have the app installed. Which screens should I screenshot? I know you shouldn't post your IMEI online, so I'm assuming I skip the "personal" tab or?

Here is 4 of the screenshots I took (I hope this works lol)

Here are the other 2 I took

All seems correct but I think your device works for Bell Mobile (BMC) only but NOT for Virgin Mobile (VMC). Try to use one BELL simcard for verify it.

In all my experience, Bell/Virgin are always interchangeable. Same with Telus/Koodo and Rogers/Fido. I tried putting a Bell sim card in though just now and it still has the problem. It doesnt load any of the signal bars or anything. Oddly enough, when there is no sim card in the phone, the bars show up?

Since it was from Bell, would flashing the Virgin Mobile firmware somehow mess it up? What are the exact steps I would need to take to try to reset it back to stock settings? I'm wondering if I'm missing anything. Or if the APN settings have anything to do with it? I set them to default already and tried adding the Virgin Mobile Canada apn settings as well

http://forum.xda-developers.com/galaxy-s4-att is the proper place to ask your questions regarding your S4, rather than where you originally posted this, the International S4 forum. Since more people with your device will be available at the given link, you may want to ask your questions over there. Or simply be patient, as this thread will be moved over there in due time.

Unlocked s8 is locked?

Hello
Can someone help me. I bought my s8 unlocked, however when I put a sim card in, it is saying "network pin locked. Please enter network puk " I have checked but I am not on any carrier. Can someone please help? And yes I have tried multiple sim cards of the same network but I still get the same thing.

Hi
Its not by phone problem. Your Sim is locked call your operator or visit. They provide you PUK no. Of your sim enter it.
To confirm this problem is by sim try this same sim card in other phone.

I tried already

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.
