[Q] galaxy s 2 cant find sim card - Galaxy S II Q&A, Help & Troubleshooting

I have restarted and reseated the sim card many times but still nothing. I have also done a factory reset and it is still the same. Also when i go into settings - about phone it shows that i dont have a number, imei etc. Anyone got anyideas ?

Have you tried entering your mobile number?

Where do you enter the mobile number because in the settings it doesn't give the option to do so.

Sudden error No Sim Card

I haven't had any problems with this phone and even made a few calls an hour ago, but now it shows a message 'no sim card ' I have reseated the sim card and restarted the phone a few times yet I still get the message. Any ideas?
One more thing, just found the sim says it is locked. Nobody had access to lock it and I haven't set that up.

does it give you the option to unlock it? i believe the default pin is 1234

Since you have provided absolutely zero information about what you have done meanwhile, I assume the SIM simply died. In case you have flashed something like baseband or ROM, next time tell us.

For unlocking an already locked SIM, you need PUK, not PIN.
Some more information :
Phone is on Telus. Not rooted or anything. I have not updated the phone, but it is on 2.2.1. I was not running a program when this occurred, I made a call then picked up the phone 20mon later, and I got the message. Also, I have tried 1234 and that did not unlock the sim. I have never locked the sim before.
Call your operator... do not see what you would solve here.

May be you can do factory reset...if still not working return to where you bought. You can search this forum, how to do factory reset.
I had the same problem after installing the MIUI ROM. However, it still showed the keypad to enter my PIN code, which I did, and the error disappeared after that.
i had the same problem, so, after a couple tests, that´s the "solution"...
take your SD card off, and turn the mobile on, will work.
after that, you can put it in again, and be alert because the time you have to insert your sim pim(sim password)is short(till the mobile finish "search for media" in your sd)
at least for me, it worked
Hi, Please help since today I´m having the same problema. No SIM card is detected by the phone, IMEI says Unknown, baseband Unknown.
HElp PLEASE!!!
First step: Install a stock rom and see if it works, backup everything first.
Second step: If first step does not work, you have an EFS corruption. Plenty of threads on this and how to recover your IMEI. Search will be your friend.

[Q] Emergency Calls only

Hello,
I have the Samsung Galaxy S II
Flashed with Dark litening rom.
Just today, this problem started. When I start up the phone I have signal for maye 5 minutes. Then I see coverage bars, but it says emergency calls only in the notification menu, and I cannot connect any calls.
I bought two of these off the same guy online about a month ago, the other one works fine so i think (hope) its not imei blocked.
I have googled it to no avail.
I have tried removing battery sim card and resetting.
I have tried a different sim card.
I have tried factory reset.
None of the above worked.
Please help.
Thanks in advance, any and all suggestions are appreciated
I checked the imei here:
http: //www . amta . org.au/?Page=405
And it says unblocked.
So it must be an error with the phone? Please help.
Thanks

Check your IMEI is the correct one that came with the phone and matches up under the battery ..
Probable you damaged EFS folder when flashing a rom .
Restore your backed up EFS folder .

Thanks for the reply, unfortunately I have checked that already and they are matching. Any other suggestions?
same Issue on my side
I try all what i can.
even another modems. No help...

Do a factory reset, wipe data and cache from CWM recovery if you have it, or flash a new rom. (Backup anything you dont want to lose).

Hi! i experienced this issue with my Samsung Galaxy S2 after flashing ICS rom. It's weird as well that when I transfer the sim to different phone and place it back again to my phone then it works but the moment I reboot my phone then I will get the same issue...
Same problem
Same problem right here about a month in to using CM7
Going round in circles...
I've now tried all sorts.
Wipe caches, factory reset, different kernels, different modems, new SIM card, battery & SIM out, reboot, chec ed if phone is barred, checked if IMEI has changed, all sorts....
Still no luck.
Can anyone help?
I found out what the problem is.
The same thing happened to me.
Emergency calls only, couldn't connect to a network, out of service state, IMEI was fine.
I went to the network operator that sold me the phone, and they scanned my phones barcode and told me the phone is blacklisted.
Go to your network operator and check if this is the case. I'm 99% sure that it will be. You ought to be able to unblacklist the phone

Sadly 99% of those with a problem have not a blacklisted IMEI they just broke the EFS and never bothered to read the fAQS and GUIDES .

IMEI is fine.
How to fix?????
And have you both asked your carrier if the phone is IMEI blocked & absolutely positively 100% ruled out a carrier side problem ? (Given a lot of these problems tend to be carrier side one way or another).

Lumia 710 Sim help needed

Hey guys i just was giving a Lumia 710 and was wondering if there was a fix to a problem im having, the phone keeps saying invalid or no sim, but my sim is in the phone, it is a tmobile phone and so is my sim, it even shows my phone number but dosnt connect to my service or anything... any help?
Hi,
Any baseband error will result in this condition. Have you played with custom roms ?
Maybe you have version mismatch wp7/rex, or baseband is corrupted. Maybe
reflash to the latest version and check.
BR
it was like this before i even unlocked it
can you provide links or any help? im a noob when it comes to wp7
Really a strange problem, if you are using a pincode, remove the pincode and see if that helps, otherwise try another simcard.
Succes,

Dial ##782# and press the call button now you can see if your phone is having a simlock, if yes search the forum.

Okay thanks, there are not much options left.
But we still have two problems, could it be the phone or the sim-card.
About the phone, did you already a factory reset and installed everything again ?
If not, I suggest to try that first.
Can you also tell me more about the sim-card, did you cut the sim-card yourself to fit in the phone, ordered a new sim, using an old one ?
First, if you ordered a new sim-card, just call T-mobile and asked them if you have to activate your sim.
Second, try to put a piece of paper on the sim-card to make it more stable.
For now I'm out of options,
Good luck,

Not registered on network, again

This thread is outdated and not related to the new problem with EFS coruption. Solutions proposed here wont help you if you lost your network after downgrading a ROM from MF6 to earlier.
Ok it's not the first thread about this but no one seems to have an answer. I'm trying again.
I flashed a custom ROM on a friend's phone i9300. After the flash the phone keep saying "Not registered on network". I tried everything I know.
I changed modem
I changed ROM (3X) (with full wipe)
I returned to stock
I installed GetRil (changed the baseband)
I installed Galaxsim (phone already unlock)
when I try to set the APN I get a message "registered on network" but when I do a phone call I got "Not registered on network"
Is there anyone who knows any way to solve this problem?

Get a new sim from your carrier. Either your sim tray is broken or your sim card is. Sim card is cheap/free to replace so try that first.

sounds like (both of you) your EFS folder is corrupt - the only way i've read of repairing it is to have a back up. service center for repair is the only option AFAIK.
The IMEISV means nothing, don't even worry about it. Know what you're talking about before you blurt out crap.

Usual suspects .
Sim you tried another .
Sim carrier unusual to be damaged .
IMEI wrong .
No phone number details standard with many roms .
Network details not entered or incorrect or wrong CSC .
Wrong modem unlikely .

First I restored the phone with the nandroid backup I made just before flashing. (still not register on network)
Then I restored the phone to stock Samsung with Odin (still not register on network)
The IMEI is still there(most thread I read with this problem people lost their IMEI)
The phone can connect to the network because it can retreive the time from the network.
If I make a network operator search it finds China Unicom(This is my sim card) and when I choose it it says "register on the network" but as soon as I try to call, I get the "not register on network" again.
I thought the IMEI might be block as it might be a stolen phone but I made a search on two IMEI database and it says CLEAR.
I flashed 3 Asian modems( I used to have a S3 I know the XXELJ2 was working with my sim card) and same result.
Have you tried flashing a different modem to your device and reporting the problem to your provider.
May sound obvious but the provider's logs may clearly show what is wrong and they can report it back to you.

anyway, tried this metod too now, and still the same ~
Hey guys, had a very similar problem to kremata (everything in EFS folder seemingly ok (IMEI and S/N were fine)), and for me it got fixed by applying Azira's Patch ( http://forum.xda-developers.com/showthread.php?t=1918601 ).
However this solution only works by rooting and if you try to return it to stock it will reverse to being a 500$ PDA sadly.
In any case, the phone is now fully functional (calling/SMS/mobile data).
hey
