(reposted from G1 SIM card does not allow connection thread)
When I went to bed on April 20th, my factory unlocked rooted HTC Desire CM7 (final) handset was working perfectly. When I woke up the following morning, I had "Emergency Calls Only" and "Your Sim Card Does Not Allow A Connection To This Network". While in this condition, I can sometimes get a 3g data connection and WiFi, GPS and the rest of the phone works well. The connection status bar shows 3-4 bars of signal strength for my service provider.
I have:
o Contacted my service provider (O2) and my IMEI is not blocked
o Tried every suggestion in every thread on the topic here and anywhere else Google sent me including toggling flight mode
o Tried the SIM in other phones - works perfectly
o Tried other SIMs in it - same error persists with another O2 SIM and a 3 SIM. The phone correctly identified that the 3 SIM was alien to it before going ahead to use it, showing that the phone IS mounting SIMs
o Rebooted.
o Factory reset.
o Removed battery for 1hr. Rebooted.
o Factory reset and re-installed a Sense Froyo Stock ROM
o Updated the Radio driver with 32.54.00.32U_5.14.05.17.zip
o At each stage tried combinations of disabled WiFi and 3g and auto-update
The nitty gritty from the *#*#4636#*#* Phone information screen contains the following (with 4 bars of signal):
IMEI: (correct code - matches the one behind the battery)
Phone Number: (my number - as defined by the SIM)
...
Location: LAC = unknown CID = unknown
Neighbouring CID = unknown
Roaming: Nor roaming
GSM service: Emergency calls only
GPRS service: Disconnected
Network type: unknown
...
Radio resets: 0
Data attempts: 0
Data successes: 0
GSM disconnect: ========DATA=======
State: DcInactiveState
disconnected with last try
at 5:38 PM
fail because Radio Not
Available
(everything else here is 0)
The preferred network type is "WCDMA preferred". Whatever I change it to, it sets itself back to that (ref bingley's solution http://forum.xda-developers.com/showthread.php?t=921812).
Turned off and on the radio a few times to try to make it see reason. No joy.
So - did I forget anything?
Can anyone help or offer any suggestions of something else I can try?
TIA for any thoughts anyone may have
Seems like you covered about all the bases. Funny, as it happened to me earlier this week. Exited a metro tunnel, had the same message. But a normal reboot fixed it.
Hope it's not a sign of things to come.
Thanks for the reply. I had no hint or warning that the phone was even thinking about considering doing this for me. No previous network issues beyond low signal ones. I've had the Desire since August 2010 and, up to this point, been loving it. Frankly - broken hearted right now :-(
Might try cleaning the contacts on the phone/sim with a little iso alcohol on a q-tip (cotton swab)
I'd try anything "outside the box"
But I'd guess the radio might be cooked. hardware wise.
While you're flashing, might as well flash your bootloader....
Any recommendations? I'm using the ClockwordMod recovery already. Really appreciating the input - any thoughts are better than silence!
As for the SIM card, I have put a brand new SIM into the phone - clean contacts, straight from a sealed packet - and put my SIM in an old SE handset I have so that at least my number is on air. The SIM works just fine. Someone suggested that I could put some tape on the back of the SIM card to improve contact, but I really think that something more fundamental is wrong here.
Update: My SIM does not work in any handset. The Desire will not connect to any network using any SIM (but shows a decent signal level).
The behaviour is as if both SIM and handset are barred. When I call my mobile number from a landline, instead of voicemail or "This user is not available right now" I get a UK "number unobtainable" or "disconnected" continuous tone back, like the number no longer exists.
O2 are claiming that both the SIM and the handset are damaged and that I need to visit one of their stores. I am feeling that something has gone wrong with their routing system for both my handset and my SIM.
Does anyone reading here have any definitive knowledge in this field that can help when I eventually do get my backside to the O2 shop?
Or does anyone have any theories?
The only thing I can think of, is that you reached a max number of transmissions.
But, I think that may be only from one of our moscow providers, and shouldnt apply to you. Basically, you do 100,000 transactions, and the sim card goes TU. But that was 3 yrs ago.
Sounds like your provider has things mucked up, especially if the sim doesnt work in any handset. I would suspect your IMEU is also blocked, but the local guy at the store doesn't know how to deal with it.
Flash it back to a stock ROM, and go raise cane at the providers store, and get a new handset.
The handset isn't from my ISP, so they are not going to replace it whatever happens. I would have to get out the HTC warranty (which should still be valid).
I can easily flash back a stock ROM - I have one all ready to roll on the SD. How about the root access - would I need to unroot it too?
When you flash back to a stock RUU ROM, is usually nulls the root access.
O mate, I have the exactly same problem! !!!!!!!!!!
Let me know if u got it fixed
I bit think it might be a virus from market.
—-- check what I post in CM's forum -----------
I'm not sure if this is the phone problem or ROM problem or SIM problem. Just post here to see anyone can help. Thanks in advance.
I've installed CM7 for over two weeks, with everything working great! But this morning, my phone showed a notification with "No SIM Card. Emergency calls only".
Well, here are what I tried to solve the problem:
1. I tried to open my phone, remove the battery and SIM card and cleaned it and insert again (i'm 120% sure it's in the right direction, it has worked fine for months!) didn't work.
2. I re-installed ROM and still "No SIM Card". btw, I tried to install Leedroid and CM7 again.
3. I reset the phone to factory setting and erased/format the SD card, which i saw somewhere online.
4.I checked the "Location & security" - "Set up SIM card lock" and found the box of "Lock SIM card (require PIN to use phone)" is ticked, I don't remember i did this! and I tried to input some PIN like 0000 or 1234. didn't work. I thought it might be the SIM card problem then, and emailed my phone carrier about the PIN. but I removed the SIM and rebooted the phone and re-checked the SIM card status, the "Lock SIM card" box was still there. Ok, I got really confused in here now.
my phone carrier replied to my email, telling me to try SIM card in other phone, if it requires PUK, they will give me PUK. (I will do that tmr) I'm thinking of trying some friend's SIM in my phone to see if the problem is in the phone hardware.
Did you try another SIM in your phone? In my case both the SIM and the Phone seem to be blocked/barred by O2 (my service provider).
Unlike in your case, my SIM is not seen as "no SIM" but as one not allowed to connect to the network. It has the same effect in other handsets and no SIM will allow my phone to connect to any network. Also, my phone does not have the "SIM lock" option ticked.
Next step will be to RUU the phone.
I intend to go to an O2 shop on Tuesday to see what they say there.
Next step will be to RUU the phone.

if you mind me erupted in this post, i wouldn't flash a rru rom since my feeling is not hardware related... if so wifi won't work at all neither sometimes 3g data.
have already use thetering?? already read that some provider close the connection if so.
I would try some other provider sim, some of them gives sim for free as prepaid.
this is just my feeling about
hope this help
Agreed - I wouldn't recommend RRU flashing unless about to claim on warranty / return the phone to the supplier. Since I have been advised by my service provider to take the phone to one of their shops I feel that it would be better to RRU first.
Yes, I have used tethering, but that is perfectly allowable in the UK and on my O2 unlimited data contract.
As I said earlier, I have tried other SIMs in my handset

so what i have already expeienced about 3G data connectivity in my neighborought.
no data connection allowed, each time a went to wireless&network/mobil network uncheck and check to see if it was able to connect, it said fail... send mail to my provider... gives me answer they gonna see blabla...
it s only few days later that i learned that they were "fine tuning" their network for improvement... hope i did'nt flash radio rom or whtever things like this.
if i were in your shoes, i would wipe /data (place where the settings are store) and set the apn settings once more (i have read that you had made factory reset isn't it?) so anything would be lost.
hope this help

My problem is a lack of connection for incoming / outgoing phone calls and SMS. Despite a decent signal level, I have the status "Emergency calls only" and when calling my number, I get a "Number Disconnected" or "Unobtainable" tone. This seems to indicate a phone with a barred IMEI. The SIM doesn't work in other handsets, indicating a barred SIM too.

I did do a reset / wipe. I made and Nandroid backup first, so when the test failed, I simply restored my settings from backup. The issues I have are not related to the APN settings, which I know inside out and can redefine (as I have done a few times) easily.
Thanks for the contribution to the thread
hi, still me
this really annoying, would suggest to cut the piece of cake or its phone related or it s provider related...
if from your mobile setting/about phone/phone identity... you should see 6 different information like :
model number + imei + iemei sv + de serial numb + phone number (not the one from provider) + imsi
you can also check your RIL through terminal with
Code:
su
getprop "gsm.version.ril-impl"
message => HTC-RIL 2.2.0028hmi (date)
THIS IS FOR MY CASE working with my radio (embedded i have not flash any RIL and would not advice to do)
only to check up if everything sound good with your phone... this smelt a provider related.
hope you can sort this
Here is my ril implementation code:
Code:
# getprop "gsm.version.ril-impl"
HTC-RIL 1.6.1062G (Apr 23 2010,17:35:06)
In the about screen, I get the following information:
model number: HTC Desire
imei: (my IMEI number - matches the one printed inside, behind the battery)
imei sv: O2
de serial numb: (not present in UK information)
phone number: (not the one from provider) - only the one from my provider shown
imsi: don't see this listed nor do I know what it is.
How is the cake cutting looking so far?
hi, so far smelt a sim card/provider problem
’International Mobile Subscriber Identity (IMSI) is a unique identifier provided by the sim card - allow gsm or umts identify the mobile user... and it's given by the sim card
have a look on this
Code:
International Mobile Subscriber Identity ( IMSI):
Each registered user is uniquely identified by its international mobile subscriber identity (IMSI). It is stored in the subscriber identity module (SIM) A mobile station can only be operated if a SIM with a valid IMSI is inserted into equipment with a valid IMEI.
There are following parts of an IMSI:
Mobile Country Code (MCC): 3 decimal places, internationally standardized.
Mobile Network Code (MNC): 2 decimal places, for unique identification of mobile network within the country.
Mobile Subscriber Identification Number (MSIN): Maximum 10 decimal places, identification number of the subscriber in the home mobile network.
more info on http://www.tutorialspoint.com/gsm/gsm_addressing.htm
so it s definitively a problem of sim card/provider...
hope this help you mate
edit: i got one and each mobile user with sim card should got one, it's a "secret" number associated with your "public" number which is known by everybody... your number call
Just to close the issue here and to offer up pointers for anyone with a similar problem, I now have some answers.
It turns out that on April 20th, my IMEI was blacklisted in error. According to O2 the bar was placed on the central database indicating that the action was taken by Vodafone. O2 have tried to lift the bar but the attempt was rejected because of the Vodafone flag.
Vodafone have never heard of my handset nor did they request any such blacklisting. They cannot lift the bar because the phone was never under their control and the number doesn't exist on their system. Their system will not allow them to handle numbers and IMEIs they don't have authority over.
This means that O2 are mistaken and that someone at O2 must have placed that entry in the barring database and then flagged it as Vodafone's work.
Just to make this quite clear - my phone is my own. Nobody says it was or has ever been stolen. Nobody has any track of a request to bar it. This is a freak accident or error, like none they have ever seen before.
So I am currently caught between the two service providers, each claiming it's the other's fault and neither able to fix the problem.
Next step - UK Ofcom.
... unless anybody out there knows of a way to make someone own up and correct this error? (no - I don't want to re-program my IMEI number).
i have the gt-i9250 and i always used an at&t sim with it with out an issue, recently i wanted to switch to t-mobile (thinking the phone should be unlocked considering it was an international phone and was the yakjuxw than i flashed it to yakju which was wierd cause i had google wallet on it and it was working fine although i only thought it was compatible with takju, but anyway all and all i put it to the usa firmware of takju 4.0.4 not going to jellybean yet, but my issue is that i am not able to use the t-mobile sim card in it and i get this (look at screenshot where signal is) what does this mean and how come i cant get signal, when i go to settings and mobile networks it shows me the apn for t-mobile us but not selected so i select it than after i go to mobile networks and it shows t-mobile and at&t and when i click any of them they tell me its unable to connect and it cant connect to the network at this time, so what would this mean and how would i fix it so that i can use it with my t-mobile sim card, also i flashed the newer NA radio uglc1.
That is weird. It should work on either of them. It just means you have no signal. That is strange. You could've actually just popped the Sim right in. It didn't matter if you were using a ROM
Sent from my Galaxy Nexus using xda app-developers app
Is the SIM activated for sure? I know when I switched to the T-mobile $30 plan it took it a good 15 minutes or so to activate, and then I didn't actually get signal until rebooting the phone for whatever reason.
Did you reboot your phone?
Although you can sometimes hot plug a sim card by turning on flight mode, taking the sim card out and toggling flight mode a few times, it won't work sometimes.
probably your cell imei not free and therefore can not change your sim.
There is an application called "****docomo" worth to release the imei. Make a backup just in case

Don't think he has a SIM unlock problem. Considering that it was working with AT&T, which never had a locked version of the GNex, I think he's having another issue.
I'd tell the OP to make 100% sure that his new T-Mobile SIM is activated and not defective, then try a few reboots and swaps back to the old SIM and do some troubleshooting. If it's the phone and not the SIM, its likely a mobile network registration error or an APN issue.
Looking in the notification bar, it seems like the phone doesn't think there's even a SIM inserted. Make sure you didn't damage a pin in the SIM tray, and that the SIM is properly inserted and clean. I don't think you'd get this error of "no SIM" if your phone was locked. If that was the case, the phone would recognize the SIM and prompt for an unlock code, which you're not getting.
hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.
"SIM Suddenly *Perso* Locked?!" <-- (Thread Tittle Typo)
Hello XDA. Mayhaps you can help me solve a problem that came out of literally nowhere.
I'm using an AT&T Galaxy Note II on Metro PCS with Cyanogenmod 13, and I have been using this setup for a few months now with almost no issues. Now don't get me wrong, I've had some hiccups here and there. Random reboots, camera issues, once I even lost ALL of my personal data for seemingly no reason at all.
Right this very moment, however, my phone just randomly rebooted, which I'm used to, but upon unlocking my phone after startup all I get is "Unlock Sim Network Pin" - "Sim Perso Locked Emergency Calls Only"
I have NO idea what is going on or why this happened in the first place. I don't have the slightest clue on how to fix this at this hour other than paying for an unlock code from a third party, but there's no way I'm doing that! Please help.
TL;DR
My phone rebooted and now the SIM is locked for no reason. Pls hlp
How did you sim unlock the phone in order to use Metro PCS? You mean the sim is locked in that the sim card is asking for a pin?

When I bought the phone off of a friend they asked at&t to unlock it and they obliged.
Yes, that's exactly what I mean. Every time I restart the phone it asks for a pin to unlock SIM.
I'll update with screenshots.
Once the phone is unlocked via code, it should be permanently network unlocked. Do you still have the unlock code?
If the sim is asking for a pin, sounds like a setting in the security may have been changed to prompt for a pin. Did you try entering 1234 or 0000?
Same thing just happened to me, what was your solution? Phone worked fine yesterday, powered down from battery use, when I plugged it back /charged it, it was doing the perso lock thing.
I'm sorry if this is the wrong thread to ask in. I'm really new to cell phones and sometimes have trouble. I have an HTC Evo 4G that's locked to the Sprint carrier. We'd like to try and put this on StraightTalk. StraightTalk's bring your own phone's website asked for some number on this phone, we entered it, and it showed the phone would be compatible with their network. If this is wrong, please feel to correct me.
I've successfully unlocked the bootloader and installed Revolutionary on the phone. I turned the SecureBit off (S-OFF). My understanding, even though this phone doesn't have a SIM card slot, the SIMLOCK feature in the HBOOT menu is a way to enable this phone to use other carriers, such as straighttalk. I believe this phone is considered a CDMA phone.
I've generated a Config.dat file using the IMEI number and put it on the root of the MicroSD card. I enter into HBOOT and select SIMLOCK. It reads the Config.dat file and then stays at Wait for AMSS Ready...
I've waited a good thirty minutes or so. It just stays there. So then I hit the power button and it gives an error message about not being a key-card. We thought if we were successful at the SIMLOCK screen, a menu would be available on the phone (once we booted into the OS) that said something along the lines of APN (Access Point Network I think), where we could add the Straight Talk stuff...
I was thinking I might be on the wrong track and might need to somehow add Straight Talk PRLs, but I'm not certain if that's right or how to go about doing that.
Is there a way to "unlock" this phone so I can put it on the Straight Talk network or any other compatible network?
I'm sorry if these questions seem really basic. I've tried searching the internet. I've found lots of videos on how to do this, but they all involve using a SIM card from another network. They even claim they're for the Sprint HTC Evo 4G.
Any help would be greatly appreciated. Thank you.
