I updated my Nexus S (i9020T) to ICS using the instructions at AndroidCentral ("How to manually update your GSM Nexus S to Ice Cream Sandwich"), but now I have no mobile service. I'm using an AT&T SIM card, but that was never a problem with Gingerbread (I just didn't use 3G).
I did notice that, under Settings > Security > Set up SIM card lock , the "Lock SIM card" checkbox is checked, even though my SIM is not locked (I used it on another phone just fine). When I try to un-check it, it asks for my SIM PIN. Nothing I have entered has worked. It always says "Can't change SIM card lock state. Possibly incorrect PIN."
Also, I've read a few things about users having to load another radio, but nothing for my specific situation, so I didn't want to risk breaking anything.
Does anyone know how to fix this?
EDIT: Or at least revert to Gingerbread?
Have you tried putting the sim card into another phone and maybe disable sim lock (pin code) there ? (like an old phone, a friends phone, or that of your wife/parent/child/sibling)
@geronimo789: Yes, I put it into another phone, and SIM lock is disabled. So I enabled it (on the other phone), and my results from the Nexus still didn't change. I still couldn't change the settings, and I still have no mobile service.
Okay, I found this thread for going back to GB. I'll try that if I absolutely need to.
At the bootloader ("Fastboot Mode"), I just noticed that my Nexus S says "Baseband Version - I9020XXXXX" Is that normal?

While navigating the hboot menus on my HTC Desire S, 2.3.5 Stock, Sense 3.0, I accidentaly pressed "simlock|"
It reported:
FAT32 init OK
Open MCCMNC file fail
Open CID file fail
It has definitely messed something up: my phone boots, accepts my SIM pin, unlocks my SIM, displays my Mobile Provider as one of the network options to connect to, but fails to register with the network every time.
So it doesn't mention that the phone is locked, or ask me to enter an unlock code or anything... but the sim that was previously working is now not working at all...
Any ideas? Will an RUU or anything get my phone back to a working unlocked state?
First of all I would try this: remove SIM card, SD card and battery (everything actually), put them back and reboot the phone to see what happen.
As the last resort, If you don't mind reinstall all your apps and data (it will erase everything), you could simply execute and hard reset:

Thanks - did that - but no luck - the phone totally reverted to factory settings, but the SIM is still not registering on the network... it seems a change has taken place at an even lower level...
The error that you wrote gives you "fail". Doesn't look like it has been done something to the phone.
Do you have any other option in hboot?
How about turn off the radio a couple of times (airplane mode) then reboot?
I found this by the way:
http://www.simonjstuart.com/2011/05...not-allow-a-connection-to-this-network-error/
I remember I solve it by playing with airplane mode and turn off the phone few times, with my friend Desire S.
It definitely did something - for 4 hours, no ability to get onto mobile network. Seems it mayt have actually modified the SIM card. I managed to get it working again - I put the SIM in another phone, booted, and then put it back in my phone and it's working again - do you think that's possibly what fixed it?
Could it be.. you never know..
That's interesting thus, looks like the SIM card got somehow "resetted" by the other phone.
I'll keep this in mind for the future.
Okay I have a very interesting situation going on. So I have the Rogers GS2 LTE. Had it unlocked over a year ago. Anyway this weekend I decided to upgrade my step daugher's Captivate with the GS2 LTE. we are both rogers customers on the same account. Anyway, i put her sim card in the phone. and noticed that it wouldn't boot. Finally it booted but got the no sim card error. so I thought that was weird and used ODIN to go back to stock. Still had the issue. Went to Rogers and got a new SIM card for her phone and still got the error.
Then today at work, I was playing around with the phone but only had my Speakout sim card with me. I was in the service menu and i was frustrated so I just started to push buttons and low and behold it reconized the sim card and started to work. I must say I was very pleased with myself that I was able to get it working. (nothing recorded on what I did of course). So i set up the phone and download most of her apps, thinking how great it was that I was able to fix it.
Well I get home and proceed to put her SIM card in the phone. "No Sim Card" again..... So thinking that I screwed it up. I put the speakout sim back in and it works fine. (Speakout runs off rogers towers). I can swap them and rogers won't work but speak out will. now the funny thing I noticed is that with speakout it always shows my data connected at 4G even when I know speak out doesn't offer 4g and we don't have any 4G/LTE near my home.
So I am really at a loss. Since it works with speakout I know it's not a hardware issue. Unless it's a really messed up hardware issue. which only leaves me to the idea it has something to do with that service menu. Now what I am going to attemp is to flash back to stock (rooted her after I thought it was working properly) and then try playing with the menu again.
Either way this is one really messed up phone lolol So anyone else have any suggestions?
Okay so the saga continues.
Yesterday I again did a firmware upgrade via "Kies" and noticed that the phone was getting signal, so i made a test call and it went through fine with the rogers sim. Then all of a sudden went to "No sim inserted" again. Today applied the firmware update again and now i get an initial message of "the mobile network will be unavailable until you restart with a valid sim card" and then the no sim inserted.
This is really starting to drive me crazy lol
Any suggestions? might try taking it back to Gingerbread and then maybe ICS to see if that has any effect. Any other suggestions?
Hey everyone,
Still trying to figure this out So i can make the phone recognize the sim card by doing the following:
*#197328640#
[1] DEBUG SCREEN --> [8] Phone Control --> [5] Simulation --> [3] HW Watchdog wait about 30 seconds then press [1] Force CP Crash.
After this, it seems to dectect the speakout sim card again and work. However after a reboot the sim is not detected again. So from my thinking it's not a hardware issue. i.e. I don't need to replace the sim card "Card" so to speak. What do you all think?

Actually i just tried this again and it doesn't always work. So i'm still at a loss on what the issue is.
A few key details:
I purchased my device via Google Play.
I'm using a SIM card provided by Sprint.
I'm not rooted. This device is completely stock.
I've tried reseating the SIM card as well as Factory Data Resets.
That said, here's my issue.
Every time I boot my device, even after a Factory Reset, a while after it's been connected to 3G (it also won't connect to LTE unless auto-activation is in progress, that's a whole separate issue), it displays an empty alert box with a SIM card icon at the top. After closing that box, it displays another one that reads some error about my SIM card being locked and that I need to power cycle the device.
I've tried everything and this error is still popping up. I'll be contacting Sprint later today about the issue but I figured I'd come here first to see if anybody knows about this issue.
Pretty frustrating, Sprint sucks, yada yada... the basics. Can anybody help?
Have you tried unlocking it yourself online under your account's page?
There should be a link next to where your device is listed.
"Get my PIN1/PUK1 unlock code" should give you the required codes to unlock it.
Might also be a bad sim card.

Does that Sim card was already activated on another device? Or did they gave you a new one?
There is a similar problem when people try to use a sim card from a current device, that will trigger that same message like yours.

Heres whats going on
I have reset the N5, and flashed the July MM image. Everything flashed fine.
I insert SIM before booting, Android doesnt see SIM... so i pulled out the SIM and reinsert while on, and it sees it.
The Signal goes into an empty triangle... It says you have voicemail. And nothing else happens.
No data, no service. *#*#4636#*#* shows the right selection, it gives me the option to turn on the radio, but if i click it, nothing ever happens.
Under phone info, it sees my phone number, the IMEI is fine, and its not blacklisted when i check multiple carrier's websites.
I just cant seem to figure out why it wont just acquire service signal even when APN settings are right.
Anyone got any tips, tricks or solutions to this?
Possibly damaged sim card or sim card reader?

dont think so, i think its software maybe.... When i do *#*#4636#*#* it will show my phone number on the top... if i remove SIM, the number becomes "unknown"... so i dunno
If it happens with all SIM cards, it could be a damaged sim reader as different areas of the SIM card contains different information? Not sure.
I have similar problem with MOB30P on T-Mobile network. The 4G LTE would work just fine (I can browse web etc), but the voice is where it is failing hard. I would have dropped calls along with calls not coming through (both calling out and receiving calls).
I downgraded to MOB30M and everything appears to working fine now. I have not opened any bug against Android yet, because I am not sure if I am the only one experiencing this problem.
Hi, I was googling for a problem like your one. My N5 does not recognise the sim at boot, but only if it is "hot". If I put it in the fridge for ten minutes and then reboot, all works fine until the next shutdown. I'm sure it's an hardware problem (already tried different sim) so I disassembled all the phone, and it looks perfect. With some cleaner for electrical contacts it can survive for some days, and then starts again. So sad, I don't want to change phone just for this stupid problem XD
I'm getting exact same issue with my Nexus 5 since CM13 0803 update, which brings MOB30Y to my phone I believe.
At first my phone could still recognize my carrier (China Unicom), but there is no signal.
Then I flash radio image from MOB30Y and the phone now cannot find SIM card completely.
Even reflashing factory image doesn't help.
I'm now trying to reflashing MOB30P to see if it helps.
Update to latest August security update radio and bootloader
it is my uncle's phone
SM-G920F Galaxy S6 (G20FXXU5DQA2)
flashed back to stock and everything is 100% stock but the mobile networks in settings is missing and the sim cards wont work, it detects them being inserted but doesnt seem to connect.
Please help, couldn't find anything
Messing around with mobile data gives "insert sim card"
tried to factory reset from recovery, clearing the cache and reset from the Smart Switch desktop software.
Could possibly be an issue with the sim card slot, does the phone show a valid imei number?

100% hw, faulty SIM reader, cold solder, or something else on motherboard.
Try to ask in Samsung authorised repair center, maybe if you are lucky like me, factory warranty would be accepted.
I just told them I bought the phone second hand and it does not recognize SIM, did not go into details
force stop stuck on s6

The same thing happened to my G920P and I was stressing out looking for a solution. Finally, I figured it out myself.... I used idonne apps unlocking service awhile ago and still had their unlock app installed on my device. After trying repeatedly to no avail to unlock again I finally started looking thru the 3 dot settings and manuvered to the IOT HIDDEN SETTINGS TAB. From there I went to the "test mode menu" setting. Then to HW Test setting, down to #7 NV Rebuild All. Clicked that and let it do it's thing and all settings returned, no more stressing. Hope it works for you.
