[Q] SIM card Disaster!...

Alright, so I have lost track of the # of hours I have spent trying to solve this problem. I have a Samsung Captivate originally purchased from Rogers, and a Rogers Sim card. I flashed a custom rom onto my captivate, which was good but still gave me some problems. I somehow ended up when clearing something in the rom getting into a bootloop, so I could no longer access my phone.
I used Odin to go back to stock, but my phone gives me the "no sim card in phone" issue. I checked by putting another sim into my phone..same issue, and I put my sim in another phone...and it works fine..so it is not my sim card. I did *#7465625#
and Network Lock is on. I even flashed to Rogers froyo rom, since I am using a rogers sim card, but still get that problem. None of the market tools for unlocking the phone give me any codes...what should I do..?

The SGS Unlock tool from the market won't work on Froyo, as far as I know (I haven't bothered checking to see if it has been updated in the past few months, but it was a 2.1 only thing the last time I checked.)
There is a froyo unlock procedure in the development section. Have you tried using that after flashing your Rogers rom?

Edit: Oh yeah, make absolutely sure you back up /efs before you do anything, or you'll have your face ripped off if the procedure doesn't work for you.

Helroz has put out an app on the market to unlock 2.1 and 2.2 phones Havent tried it yet.... worth a shot...

kind of confused. I mean, I originally purchased my phone from Rogers, and my Sim is from Rogers. I am not sure if it was always locked to rogers, but it just says "no service" and doesn't recognize that I have a rogers sim card. even if network lock is on, shouldn't it still recognize my sim? The methods you have posted have not worked for me. Perhaps I should see if I can get an unlock code from Rogers themselves. If I could do that, would that solve the problem?
Also, if I somehow managed to get an unlock code for my phone, where would I enter it? Would I have to relock my phone to rogers? Could someone explain how I would do that?

Did you try a factory reset from the settings?

I have done a factory reset before, but i'll try doing it right now...see what happens.

ok I just did a factory reset...still telling me there is no sim inserted even though there is..any other ideas?

Alright so finally everything is showing as "OFF" including Network Lock but it still will not recognize my SIM. i did another factory reset but still no luck. Any other ideas??

What does it say in your APN Settings?

Can't access APN settings. infact, just going into "mobile networks" gives me "insert SIM card" even though it is already well-inserted

Sorry - I meant to say mobile networks - brain fart
[EDIT] The only thing i can think of would be to check the pins that contact the sim card... see if those somehow got damaged. Also check to ensure they are clean, blow out the sim card holder and if needed give the pins a wipe to clean them up and try again. If all else fails, try to get your hands on another sim from the same carrier and see if it works. If a different sim works, then yours is hosed most likely...

It's okay guys I managed to solve things in the end! thanks for all your help tho

I wonder...I just couldn't bring myself to pose the question

for self-pride(not that I have any left after spending god knows how many hours searching in a hex editor for non existent damn unlock codes) I refuse to state how i resolved my issue -______________-; (cough). but THANK YOU ALL for your support anyways! I have definitely definitely learned from this horrible mistake.

bet it was inserted backwards

Well, I'm not sure about the problem; if you are on a custom rom, it might be because of that, or incorrect flashing. Try using another ROM, and if problems persists try Stock ROM meant for your region. (it might be possible that you flashed a ROM for a different region and because of that you might have a problem..)
AND NEVER POST YOUR IMEI NUMBER ONLINE.

Thanks for the advice about IMEI number, i didn't think of that because i went crazy because my phone doesnt work.
I'll try with stock rom.

I flashed original stock rom on the device, but the problem remains. Does anyone know the solution, I am going crazy

pop your sim card out for 15 min. then put it
back in your phone.

In the second pic it is clearly showing 1 bar of signal
So how can you say sim is not being detected

No way out here

Did you notice the the SIM symbol with question mark inside it?
The phone acts like there is no SIM card inserted when it is inside all the time.

[Q] Invalid SIM card error/SIM network unlock PIN request on boot I9305

Okay, I posted this question in the I9300 Q&A section by accident (was a bit distraught, didn't read the section title properly), but for some reason a mod appears to have deleted the thread instead of moving it, so here it is again in the correct section.
So after using my I9305 for about 8-9 months now, I woke up this morning to find my phone nonoperational. The phone requests on boot a "SIM network unlock PIN". If this window is dismissed, the pulldown notifications drawer states "Invalid SIM card" with subtitle "Network locked SIM card inserted". Quick Googling reveals that these notifications and errors typically show that a phone is locked to a specific carrier. Now that's understandable, but this phone is unlocked, and I hadn't even taken the SIM card out until this error occurred. The SIM card works just fine in another phone.
I've tried rebooting the phone (first port of call), and using the code *#197328640# in the dialer to SIM unlock as per this post (but I didn't have "[4] NW LOCK NV Data INNITIALLIZ" as an option). I tried using "busybox chown 1001:1001 /efs/nv_data.bin" in terminal emulator as root, after seeing this post, but it came with an error of "chown: /efs/nv_data.bin: NO such file or directory". So... how bad do things look? And no... I don't have a backup of my efs. =[

Since then, I also tried *#06# in the dialer, and my IMEI is intact.

Nope, no dice.

Are you totally stock rom or custom?

Stock standard 4.1.2, with CF-Auto-Root.

Maybe try flash a stock pre-rooted rom by lriquidperfection with odin and try the *# again?

Tried various different stock ROMs and factory resets, nothing.

You need to flash a 4.1.1 ROM, or at least a modem from such a ROM.

Not sure why doing anything with the battery would be in any way related with the SIM. I also forgot to mention that I had already tried cleaning the SIM card at the start with alcohol. In any case, the SIM card works fine in another phone, so it appears that there isn't problem with the SIM card. In any case, I managed to RMA the phone, now the long wait to get it back...

i not joke with you
i have same problem with you 5 month ago with copy battery

Got my phone back from the shop today. Kept an eye on the shipping tracking when I sent it out, and they sent it back out half a day after they took delivery, so I'm guessing they used a SIM unlock code since it's definitely my phone that I got back. Didn't have to pay anything, so I'm happy. Still not sure why/how the phone decided to lock itself though...

Few days back, I was just messing with my phone settings and. I went to dialer and typed #*#*4636#*#* and without knowing what SMSC number is, I changed it to my phone number and since then my sim card isn't working?.
I did factory reset from TWRP and flashed the Stock 6.0 but still Sim card is not detected.
I tried updating to default but getting update error. Even tried resetting it from a Non-Android phone but didn't work.
Please help....??

Question Sim Card Does not work

Hi All,
I was hoping someone would be able to assist this issue that I am facing. I have a S21 Ultra purchased a couple of years ago in Sydney, Australia.
Recently, my SIM card stopped working on my S21 Ultra. Every other feature works and the SIM card works fine on a different phone. I have also tried replacing the SIM card, but it still does not work. The same SIM card works on a different S21 Ultra phone.
I also reset the network settings and yesterday I performed a full factory reset, but the SIM card still does not work.
I tried searching for a solution here, but could not find any threads where someone has faced a similar issue. If someone could kindly help or suggest some other tips, that would be highly appreciated.
Cheers

Have you tried putting another sim card on the current slot that isn't working?
You have the following two options:
1. Assuming your current sim is in slot 1, try putting it in slot 2 (or vice-versa).
2. Try eSim with your current number.
The issue appears to be the firmware that came with the latest OTA update.

Yup, I have tried another SIM card but that doesn't work. That sim card works successfully on other phones. Also I just have a slot for a single physical sim card. Thanks

If a factory reset doesn't solve a problem, you'll have to wait for the next update. For now, eSim seems to be the only solution.
