Hi,
I purchased a new S2 the other day. Everything looks great so far, except that when I put in my existing SIM card, it only reads partial information (i.e., number, recognizes it is Vodafone, etc.) but fails to get register on any network - it stays in it's emergency calling mode. I've tried three other sim cards with the same results (all on different networks).
It actually seems like there's a problem with the sim reader or the network registration function, but I'm not entirely sure how to troubleshoot. The phone is "unlocked" - dialing #*7465625# confirms this.
Any ideas?

It sounds like you have a hardware issue with a defective sim reader.
You can not trouble shoot return it to the store for another one.

Here's my problem, hopefully somebody can figure it out before I give up and sell this to somebody with AT&T.
I received a freshly refurbished AT&T 8525 (from ebay) and wanted to use it with a T-Mobile SIM. I upgraded to the latest AT&T distribution (WM6, downloaded from HTC), ran the HTC_Hermes_SIM_CID_Unlock_v3a successfully, put my SIM in and everything worked. After calling a friend and talking for about 5 minutes, the call mysteriously ended. I tried recalling (wouldn't connect) and then restarted the phone but it wasn't getting a signal.
Fearing the worst, I tried flashing the latest radio, rerunning the Unlock, and flashing various other ROMs (including an HTC, Schap's, and Pv Dvh Wm6.1 19209) but there was no change. The icon on the Today screen would either give an exclamation point or just continue scanning. If I went into the phone settings and tried to switch to manual network selection, I would sometimes get a choice of T-Mobile or Cingular but any connection attempt would result in a "Failed to register to network" message.
My SIM card works perfectly in both my old phone (HTC Tornado) and an older unlocked Nokia.
My last attempt was to put my friend's AT&T card into my A&T 8525 and it connected just fine with calling ability and everything! I've since run unlock many times, reflashed the radio, installed other ROMs and installed various version of Hard-SPL but none of them seem to be able to connect to the T-Mobile network using my SIM card (but have no problem connecting with my friend's). I can see the phone book on my SIM card so I know its not a bad SIM connection and it does not prompt me for a password (as it first did when I placed my SIM card in the phone when I first received it) so I'm pretty sure it is actually unlocked.
Any help whatsoever would be greatly appreciated!
Try borrowing a friend's phone with AT&T, shove his sim into your phone and talking on it for a few minutes and see if it still happens there. If It doesnt then try your SIM again. Also, try reflashing your radio without your simcard inserted.
I tried reflashing the latest radio without a SIM, then inserted my SIM but there was no change. I'll try talking on it for a while with my friend's SIM and see if anything happens, but I'm doubtful. Thanks for the help. Any other suggestions?
I've noticed that when I go into Settings>Phone>Network and select Manual, all the cooked ROMs I've tried end in a "Cannot read settings from the network." while AT&T's gives a selection of T-Mobile or Cingular (neither of which actually let me register to a network, though).
I put my friend's AT&T card in and called my own cell phone. The connection died after 5 minutes, but then I called my own cell phone again and they stayed connected for 10 minutes before I ended it. I put my SIM back into the 8525 and still no signal.
While the AT&T SIM is inserted, the Settings->Phone->Network screen is different. It just says:
Current Network: AT&T
and has a button for Find Network which just pops up a window saying "Registering on the network...
Any other ideas?
Send it back to whoever sold this to you on ebay. Not worth all the hassle that you are going thru. I have the same phone and bought mine off ebay as well. It worked perfectly out of the box with no problems. I have t-mobile and when I placed the sim in - bam - the phone just worked. I had to configure the pop3 email and mms settings manually, but that was it. I have htc's wm6 on it.
Thanks for the advice, but the first one I got from this guy the screen died after a couple of days. He said it was under warranty so I sent it back to him to get it replaced and it took him 3 months to finally return it to me. I really don't want to deal with him again.
I was wondering if there was a difference between the SIM cards. Could you please run the "SIM Manager" Application on your phone. Then go to Menu>Tools>SIM Information and check out the numbers there. Mine says:
Total Phonebook Size:
250
No. of Phonebook Entries
20
Max. length for name:
16
Max. length for phone number:
50
SMS Message storage capacity:
30
Although my friend who has an AT&T 3G SIM has slightly higher numbers for max. length of name, phone number, and SMS storage capacity.
I've also heard some stuff about specifically asking to get your account 3G enabled, but I'm not sure if that has anything to do with this problem.
I figure I'll go down to a T-Mobile store and see if I can get somebody to let me try a newer SIM in the phone before giving up completely and selling it.
That's too bad. I bought my phone from zendoo and they have a pretty good rating off of ebay. I'd hate to find out that your ESN or whatever is corrupted. Here are my settings
Total Phonebook Size:
250
No. of Phonebook Entries
11
Max. length for name:
16
Max. length for phone number:

Oh well, I guess I'll see what I can sell this for, wait until my contract is up at the end of summer, and then see what new phones are out then. Thanks for your guys help.
Hi All,
I have a Galaxy SII, which I rooted and flashed with ICScrewD ♦♦♦♦Homemade Ice Cream
http://forum.xda-developers.com/showthread.php?t=1375255
It worked fine for a couple of days, now all of a sudden I am not getting any signal on my phone, and instead of the signal bars I am getting the no network symbol. I tried different modems, different ROMs, doesn't seem to work. I even went back to the stock, but no luck.
When I went to the wifi & network settings and tried to click on the network settings it says "insert sim card" even though the sim is already in there. I tried my sim on a different phone, it works fine. So i am guessing its not At&t's fault.
Has anyone else had the same problem? Any help is greatly appreciated.
When you re-inserted your sim card back in your GS2, what happened? Is it an old sim and are the contacts worn and scratched?
The contacts are just fine. Even when i reinsert it nothing happens, I still get the no network symbol. It is basically behaving like no sim is inserted.
Well it sounds like a trip to an AT&T store might be in your future to test another SIM card. Hopefully that's all it is. Wifi radio works fine?
Try reflashing back to stock?
The wifi works just fine, and i tried flashing it back to stock, did a factory reset also, but nothing seems to work.
I have not dropped my phone even once, so that rules out the physical damage.
Well not sure this will help *fix* the issue, but might provide a bit more insight into what exactly the phone is and isn't seeing. If you download Elixir 2, linked below, and run a report and send it to yourself via email, look in the Telephony section of the report and see if the phone even sees the SIM card. Obviously it sounds like it doesn't, but if it gives you your SIM serial info in there, you might be able to rule out an issue with the actual card itself, etc.

Nope, it says sim state is unknown, I guess i will have to go to the At&t store then.
Thanks anyways.
Hi,
Recently, my canadian galaxy note stopped reading all sim cards. Ive tried flashing various roms but still nothing. All I get is the insert sim card icon in the task bar.
There are tonnes of threads regarding the international version, but i was wondering if anyone else has experienced this?
Just had this problem. If avail swap out sim cards with a known working card and if it still fails to register, the phone needs to be replaced.
Just happened to me yesterday and got a new phone today!
Hope this helps!
I am currently having the same problem with my ATT Note, but I am sending it to samsung to get fixed or replaced under samsung's warranty.
First check if your note has a an imei number. Go to settings about. There's also a # shortcut but I don't recall what it is. If not efs got corrupted some how. If you did the shortcut key if efs is corrupted it should display null/null. (I've got a captivate with this problem)
Sometimes it's a bad sim contact. Just by a worn out sim card, its happened to me. Clean off the contacts or get another sim card provisioned. Costs $6 for a new Rogers sim provisioning is free.
I have unlocked my i717 phone, sim card read fine on Family Mobile service powered by T-Mobile. Then rooted phone using Odin. removed apps I didnt like. after removing Kies air and a few other AT&T apps. I got the alert at the top area no sim | emergency calls only I turned phone off then back on same issue. I return phone to factory setting another issue also didnt use odin to unroot. however I did download full ICS file and used odin to unroot then wiped clean to factory setting. The issues with sim card not reading still remains. I do have another i717 and check with hardware change of sim card reader as well as checked sim card its self in another phone and it works fine.
check with local phone tech guy he said I might have an issue with IMEI change when doing the first root? he also told me to come here for help.
How can I check if this has happened?
How can I change it back?
How can I change it to work with my Family Mobile service powered by T-Mobile?
Thanks

Seldom an IMEI issue. It's typically fixed by replacing the sim holder/reader. Before you do that I would swap the readers and see how each behaves in a different phone. If the culprit reader does not work, $10 on eBay or so. Utube for video instruction-it's ez peasy. Lastly unless you really have to avoid removing and re-inserting the sim card. something about that makes my device nuts.

I have tried the swap of the current Sim readers assembly with another Sim reader I have. and both Sim readers assembly are reading great on another test phone. Being that the hardware cross testing is showing that the Sim card and Sim card reader are in fact working and not the issue. This has lead me to do more research on the IMEI issues along with a possible missing EFS/bin files?? I didnt backup my phone EFS/bin files before unlocking which can cause the issue with the Sim card reading I am having...? still not sure tho..
I have learned that the IMEI hasn't been changed like I had thought tho..its the numbers after the / in the IMEI are just software revision numbers to reflect the software version.
Does anyone have any ideas where I can get the missing EFA / bin files > nv.log > nv_data.bin > nv_data.bin.md5
My phone (BE2029) has no signal (the card is identified as normal), doesn't matter which slot the sim card is in (card works, checked on another phone). Can this be a software issue or necessarily hardware? What are possible fixes? What other information do I need to provide for the issue to be identified if what I provided is not enough? Where else could I post this to try to get help (posted in r/oneplusnord a while ago, no response)? Any help or information is appreciated.
How did you get the sim? If you got it from a retail store, you could probably trade it in for another. Is this a new phone? New in box, or did someone have it before you, and break it (flash bad radio ROM, etc)? If the latter, I'd search here for the EDL mode tool to reflash the ENTIRE device to stock (other than IMEI etc).
When you first connected, did your carrier feed you the APN info (usually automatic)? Do any of the apps that show cell info show that your phone is seeing cell towers? If you go into the SIM settings (Wifi&NW -> Sim & NW -> Sim Setting, does it show the SIM as active? You can futz with the settings there, including picking a network manually (not recommended, but who knows...). At least for me (T-Mo) you can get the "right" answers from their website.
Hope that helps...
Would try the cell tower check, but since then, the sim card broke as well... Sorry, thank you for your help (I really wanted to know it too, but when I put the card in, it broke so I decided not to put any more sims in it)
