Ever since i updated to official froyo, Jk4 / JL2 etc. I see that my phones network disappears for no reason. The sim card tools option is also gone. It says that there is no sim card even though there is one. I thought it was a lose card or something I stuck some paper behind the sim card and it worked. After a while, it started doing that again. I even got a new sim card but it still keeps doing that. Anyone know how to fix it? (Factory reset has been tried).
Thanks You.
Ps: has anyone else been experiencing xda forum app force closes lately?

Last night, before I went to bed, I noticed my phone lost reception. I didn't think anything of it and went to bed. Today at work, I still have no reception. Of course I checked to make sure the actual phone on comm manager was on, but it just keeps searching. I did have my phone overclocked to 273, but I dropped it to stock speed with the same results. I even did a hard reset and it does the same thing. I tried to go in an manually select a network, but it just says searching. I'm running Open Touch 3.0 Biggy. Any ideas or suggestions? I've heard that sim cards can go bad and cause this, but mine seems to be working. I can still access all my sim contacts.
Thanks,
Nevermind....
Okay, so I found someone who had a tmobile sim card, and swapped with their phone, and their sim card works in my phone, but mine won't in theirs....therefore, bad sim card. It's weird though, because I can still access my contacts though. ....off to buy a new sim card. Man, I'm glad its the card and not the phone. Waaaaaay cheaper to fix.
As much as I love this phone, it has gone to complete ****.
First the loss of cellular data. Blamed that on the SD card, so whatever. Was able to get it to work for the last month or 2.
Then I could only get my text messages 10 at a time after a soft reset. Was fine with that for now. I was just hoping the update coming out in a couple weeks would fix that issue. Figured this was caused by the SD card too.
Then my WiFi decided to stop connecting to any wireless network. Again, thought this was caused by the SD card. I couldn't take it anymore so I took the battery out, the SD card out and the SIM card out. Put it all back in, started the phone back up, and nothing. All my info was still there, but couldn't connect to any cellular network (on AT&T), and couldn't connect to WiFi. So I thought, okay can't live with this, and I did a full restore.
Booted up after the restore and went through the initial setup, and son of a b-word...won't recognize the SIM card. So I removed the SD card and did another restore. Same thing, SIM card error. Took battery, SIM, etc out, put it all back in, did another restore, blah blah blah...nothing.
So I put my SIM card in my old iPhone 3G and it will connect to AT&T with 3G, but says I don't have a data connection (I'm guessing because I don't have the iPhone specific plan). So why the hell did my focus all of a sudden decide to not recognize any SIM card? I think I've had it with this phone. This is my 2nd one and it's been nothing but problems. I understand it's probably because of the SD card, but now with no SD card installed I am still having problems. I'm tired of it.
Might not be related, but since last week, I've also been experimenting SIM Card Errors. Usually after a soft reset it will fix it. But it's been happening a lot every day. Put the card in another phone and no problem. I dropped the phone 2" two weeks ago, but didn't get the issue right away. Strangely started happening too as Samsung came out with an update to their Network Profile app. Will try a hard reset, but not looking forward to it.
I'm new to this whole world of GSM. I've been CDMA for 10 years+. So forgive me if this is common knowledge.
I have a N4 using a Straight Talk Tmobile Sim Card that was cut. This is the 3rd time this has happened in about 3 months. When suddenly my phone says no sim card.
Ths 1st time I flashed the louder add on app. Then to get it back working a restore didn't do it. I needed to flash a new kernel.
The 2nd time My phone was install tons of apps and then it rebooted, came up with no sim card. I flashed the update for my rom PA3 since I downloaded it anyways, and that fixed it.
This 3rd time my phone did not reboot, but I was in church had phone i silent, pulled it out pocket no sim installed. Before I do anything else just wondering is this something to expect? or do I have a bad phone, rom, sim or whatever else? And what's the best way of fixing it? Feels like im throwing jello and something is sticking.
Thanks!
EDIT
I've used a non activated sim card, and it does not even see that I just installed it.

Use a real micro sim, not a cut sim.
There is no option for Tmobile and straight talk.
I dont think its the SIM anyways.
Because I installed a micro sim (not cut) into the phone and the phone does not see it neither.
So, I have had the phone since the initial couple of batches first shipped out. No problems whatsoever, but now my SIM card is not being read at all.
Only just atarted happening a day ago. Restarting fixes it temporarily as well as removing the SIM and turning the phone off and on before putting it back in. The issue starts again after awhile and is super annoying.
If anyone else has had the issue and fixed it, I would appreciate the help.
Everything on the phone is stock. No root, flashes, etc....
Bump.
Anyone with the same issue, lol?
It really sounds like a bad SIM. Do you have another phone or SIM to test? If not, it could be worthwhile to try getting a new SIM from your carrier. Or, backup your data and do a complete factory reset and see if that fixes it.
Just picked up one of these phones. Really like it so far! One issue I've noticed though, after a few days of ownership, it's randomly dropping/not detecting the sim card? It's happened at least twice where I've left it to charge over night and woke up to the no sim icon, and yesterday at some point while I was watching YouTube videos in full screen (in my hands, off charger, no notice of the drop either whenever it actually occurred). Quickly popping the sim tray out and in resolves the issue. At first I thought it was because I was using a manually cut sim card, so I've since replaced the sim but the problem persists.
Anyone else have this issue? Should I have the device exchanged?
Thanks
First the phone froze and after restart dropped sim
I just had the same issue occur just now. The phone had frozen for over an hour before I did a forced reset and now when it started back it shows no SIMCARD and no connectivity. I am like you, I really like this phone but hopefully this isn't a permanent issue.
Watched it happen just now. Goes from bars to no sim icon without error or notice. Resetting the network settings, resetting the phone, and powering it off/on won't fix it. Literally have to pop the sim in and out and its recognized right away.
I lost sim recognition after I flashed to LOS 11/30 and no matter what I tried, phone would not recognize the sim. Once I flashed back to stock, it came back. Hopefully this was due to the rom and the problem won't come back.
I am not sure if I lose the SIM, but I will say that when I am driving around with Android Auto, I constantly see the cell signal go from LTE to no signal every couple minutes...

Had same issues when I flashed back to stock I actually have better signal than when I got it out of the box.... Almost as if the software wasn't installed correctly or something
Same here I'm on the stock room. I'm wondering if it is an app I downloaded. Any idea how to wipe cashe not the apps but system.
This is happening at least twice a day now. It seems to be software related. Power off and on without taking out sim fixes it.
