I'm having this problem which started right now, without even rebooting the phone or doing any kind of procedure. The phone accepts the pin code for the sim card, shows signal on the notification bar, but I can't make any calls, and it doesn't recognize the network on the notification bar - however, on the phone information area it has no problem recognizing the network.
Any idea on what's happening? I'm on JPU btw!
edit: after a couple of reboots it's working again Well, the problem is solved; still, should I be worried about this behaviour?
how did you solve this problem? im having same issues
this is crazy i am having the very same problem, my I9000T was on charge i shut down my pc then disconnected the I9000T, and since then it does not see my sim card, i have tried three different sim cards without any luck, the phone is rooted, and funnily enough i was reading about Darky`s v8 rom as this was my next step i wanted to do today GGRRrrr does anyone have any ideas on this, or do i unroot it and take it back to the shop i bought it from ?? thanks and regards in advance

Hi Everybody.
Well, i bought my Samsung Galaxy 6 months ago and it's a awesome phone, but now I've got some issues.
4 Months ago - My phone comes with froyo 2.2.1 so I decided to update it using kies to Gingerbread 2.3.3, after that, My phone starts to had some issues, first when I press the home button the phone didn't response, the screen was in black but I could get calls, messages and lisening to music, this was solved after reboot the phone but in any time could happen again.
Now - because the issue before, I decided to use Darky's rom 10.1 and the issue suddenly dissapear.
After 1 moth and a half I decided to flash Gingerbread 2.3.4 stock rom and a new issue appears and since there, I can't solve it.
Sometimes, my phone get lost its signal and when to "Network Selection" a message comes out "Insert Sim Card to access network services", I can't do any call o use 3g, the only way to solve it temporarily is rebooting the phone.
I use many versions (JVP, JVQ, JVR, even MIUI) but the issue still happen.
Please, I'd aprecciate if you can give some help to solve my problem.
Regards.

Hello.
Yes, right now my phone has another sim card and everything is fine, but this SIM hasn't got any plan with internet, maybe the problem is when the phone use 3G.
Regards.
May be your sim has problem not ur phone.

That's what I thought, but I changed my sim card when the problem began.
Should I change my sim card again?
Regards.
I think he meant changing a new sim card with the phone company?
Yes you should replace that sim card from your company.

ok, I'm going to chanche my NEW SIM CARD (becase it's new) for another one.
I hope this will solve my problem, I'll let you know if everything is ok or not.
Thanks.
I have just solved a similar problem with my Samsung Galaxy S I9003.
The reason was software unrelated but seemed to be a hardware connection problem. The phone was unable to access the mobile network showing a "No Service" status, also the IMEI number was unknown on the phone settings. The mobile wasn't even requesting the SIM Card code when it was turned on. But the rest of the services were working properly (wifi, bluetooth, etc).
Although i tried everything such as re-flashing, re-rooting and even IMEI restoration techniques such as in youtube "Samsung Galaxy S (IMEI Restoration Techniques)", I was unable to fix it.
The solution was to open the phone and just adjust the sim card slot connectors. I will keep the phone on testing to see if that happens again.
Hey All;
Long time lurker on XDA, first time poster. My phone has been behaving badly, and thus far my googling, and searching XDA has not found any answers; so thank you in advance for any info you can provide.
I have and HTC HD7 (Bell Canada network). This morning my phone rebooted a couple of times, and when it "rebooted" the last time it just hung at the HTC boot screen (white screen with green HTC logo). First I took apart the phone and reseated the SD card. That in itself didn't resolve the issue, but I was able to do a factory reset and got the thing booted.
Now suddenly I am not able to get any service on the phone. It is not giving me any indication that there is an issue with the SIM card, and I even tried it with another known working SIM from my girlfriends phone to no avail. Also oddly, I have connected the phone to my PC, and tried to update it. It will update to 7.10, but will not detect that the mango update (7.5?) is available.
Seems very odd that suddenly the phone would now have no service, and I'm thinking that it must be related to the issues I had this morning. Any thoughts on what could be causing this?
Thanks!
Phone acting wonky/no service
About 6 month ago I had an issue with my old Samsung Omnia 2 using Bell Mobility as well...My phone would continually show no service or jump to roaming mode...A call to bell mobility help line and a good rep indicated to me the sim card was recalled due to issues..A quick trip to bell mobilty and a new sim card fixed the issue...Hope this may help you..I now have an HD7 with the same replacement sim card no issues...
Nope... I manged to get reception for a little bit earlier tonight and then it stopped working again. Pretty sure I must have broken something in the antenna when I remounted the SD card. Tried to fix that problem and now the phone doesn't even power on. Great another $300 device down the toilet...
Hi chaps, I have tried searching across the internet with no luck, here's the deal.
I bought this p1000 galaxy tab some days ago from a guy on a forum. tried it thoroughly before paying, inserted my phone SIM, got a phone call, sms, 3G internet, wifi, all working flawless. I used it for some days wi-fi only waiting for my new tablet SIM to be ready.
Monday, I receive the SIM but it still had to be activated. I just kept it in the tablet waiting for it to be OK. Zero problems, just the usual "no service" message like you would expect from a sim that's yet to activate
This morning I finally get the SIM activated, but as soon as I try sending a text or something, the tablet just shuts down. After that, no way trying to boot it up again: it reaches the Samsung logo, then bye bye. If you remove the SIM from the tray it magically comes back to life.
I already tried the usual stuff, like hard resetting and like, cleaning the SIM or something. I also tried with another carrier sim and I get the same behavior. I'm starting to believe that there is some hardware fault with the SIM reader, but I thought I'd try to get some hints from here before calling Sammy's assistance. Also the weirdest part is that it worked some days ago!
If anyone has any idea/experience to share, I'd love to hear from you mates. thanks in advance!
(oh and btw I know how to hit a thanks button)
I'll update the post with further intel, maybe it will help someone down the road.
The tablet does not like freshly activated SIMs. I know it sounds crazy but that's where we are at. We have tried like 4 different SIM cards from different operators, all work flawlessly; The SIM card of the above NOW works flawlessly as well, it just needed a couple days to settle down. I have no idea if this is a software bug, a hardware fault or some strange network settings from my carrier, but the problem seems to be solved for now. Luckily i didn't send it in for repairs!
This morning I updated my note to 4.0.4
After updating it suddenly I wasn't able to make any calls or messages. I did some research and I have discovered that my phone had suddenly re-locked itself and is unable to allow my sim to work with it.
After doing more research I have rooted my phone and tried the Galaxy S unlock (which supposedly worked with the Note), and ended up with something like the attached picture. I see random icons but no specific code.
Here's a little background info that may be useful.
I bought this phone over in HK while I was there for vacation. The network lock occured when I first bought the phone but then the store that I bought it from found a way to fix it (without rooting the phone). Even when I upgraded to the OTA ICS there was no problem at all. I don't know why suddenly with this minor update it reset the network settings.
When I look into the mobile networks on my phone's settings a window pops up saying "Insert SIM card: Insert SIM card to access network services".
Which to me was kind of weird since I have inserted my sim into another phone and is able to make phone calls just fine.
Please help me! I have no way of contacting that store that I bought the phone from and I'm in need of getting my phone to work asap.
I am not lazy or anything, I have spent the last few hours trying to figure out how to solve this problem.
I have no experience in flashing a new rom and I really don't intend to do so unless i have no other choice.

You can - I believe - Downgrade to GB and run the unlock tool mentioned in that thread then upgrade again to your ICS..
Will this help?

used this mod and its working
I've had my GT-N7000 for about a year. It has been rooted and running various ROMs since I had it and has always worked wonderfully. I had settled on CM 10.1 about a month ago. Since the last 3-4 days I noticed that my 3G signal showed no bars from time to time. Normally, just a quick 'airplane mode' dip and everything would be fine.
2 days ago was still having the same problem and I had to completely turn off and on again to 'maybe' get a signal. If I got a signal, it would only stay there for a few minutes and then disappear.
I changed the SIM card yesterday just to be sure but I still had the same problem. The same SIM card works perfectly well in my GT-I9000 running CM 10.1 as well.
I cleaned the SIM slot contacts, verified the internal antenna wire and even flashed a few modems and still have short lived and intermittent 3G signal. Any idea about what could be happening? Could it be the 3G radio failing on me?
Thanks for any help.
JF.
Anyone?
Does this happen after you move from one area to another? For instance from work to home or Vice Versa?
same problem
Hi there,
I've got the same problem than you. I got my Note 1 year ago, and since few days, I've a problem with the SIM.
On boot or reboot, the SIM is perfectly recognized and works good. I can call without problem, and can connect to the wifi without problem. The problem is when I use 3g, the SIM is not recognize after 1-2 minutes. I mean, I can access internet, do whatever I want, for just a minute or two. After that, the signal drop instantly. I tried:
plane mode: doesn't come back to normal mode cause the phone says there no SIM card
change modem: don't resolve the problem on all XX*** modem for JellyBean
change ROM: I was on German-leaked 4.1.2 Stock ROM, i tried 4.1.2 Switzerland ROM (where I live), 4.1.2 custom ROM and cynogenmod 10.1 (4.2.2). Always the same problem.
Tonight I'll try another SIM in the phone, in the case that the SIM is the problem.
otherwise, I don't know what else to try...

You're ****ed if it's the same problem! I tried a lot of technique and the one I warn you about is changing the RIL. Useless waste of time and ****ed up everything. At the end I tried an app available on the play store for thé modem, can't remember which one. But hey, you're on the track!
Good luck

Are you sure it is the radio causing the problem and not the antenna? I know on mine, the USB charge port can be a real PITA when it
goes bad, and I had to buy about 3 before I found one that worked properly. With the wrong one, the radio signal would fluctuate all
over the place, so that's why I wonder if it could be a bad antenna/connection/board problem, since it is contained on the same
board as the USB port?

I had an update..
I figured out that when i change the network mode to GSM ONLY it runs very well and never drops network signal or get the NO SIMCARD message..
but when i change the mode to AUTO or 3G/CDMA it drops network and gets NO SIM CARD after a few minutes !!
still don't know the reason & still searching
Let's talk about this problem. Mine is similar. Not getting errors with aim card but when i place or receive calls while in wcdma mode, conversation is normal at first place, then after few seconds i can not hear other side, and other side cannot hear me, sometimes that call ends and that is it. On gsm only, calls work normally, but internet is not working, while in wcdma internet works... pretty nasty issue. I tried flashing different roms, tried several modems to flash, problem is not disappearing, but from modem to modem i can see improvements. Sometimes it does not drop at all... can you help me with this?
