(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).
Hi:
I'm on Bell, and I've been happily using the same Cyanogen build for months (7-05252011-nightly according to the about phone settings).
Without warning, three days ago the phone aspect and Internet have stopped working:
1. The phone strength indicator in the notification bar shows zero bars and a tiny x.
2. There is a new icon I've never seen - a white rectangle with one corner cut off and a black exclamation mark inside of it (SIM error icon?).
3. The APN list is blank.
The IMEI is listed, but my phone # shows as unknown, network shows as unknown, mobile network type is unknown, service state is out of service, and mobile network state is disconnected...
I have tried to search networks, or select automatically, but both give me errors.
I have tried adding the Bell mobility APN repeatedly, but it wouldn't save. Is this a problem with the phone, Android, the SIM card, provisioning, or something else? I fear I would have to return everything to stock in order to send it in for repair, so I'd like to try whatever else is possible before then.
I tried removing and reseating the SIM card, but no luck there either...do these things just fail for no reason?
Thanks very much in advance - so frustrating...

Have you been messing with the radio recently?One time I had a problem with losing my APN settings,not been able to save when manually entered,and a sim not inserted error was after pushing the radio ril files over to phone,just a suggestion,have you a nandroid backup to go back to?
Nope, no ROM or radio fiddling...

I would reflash a the rom and see if that fixes it
Just installed the latest stable Cyanogen mod after backing up and wiping the system and cache - same problem...can a hardware flaw develop over time like this?
The only other thing I can think of would be to flash a different radio, the radio in my signature is popular.
Some people use a superwipe program which could also be worth trying,if that does not fix it, then to me sounds like a hardware fault has developed,or there is a problem with your provider.
Thanks - I think either reflashing then recovering my ROM, and/or reseating the SIM card made it work. Whew - what a relief
I have a canadian based S3 I747 and its unlocked (any sim card i insert it wont ask for the unlock code). However, no matter what i do... (root, update a non carrier rom, carrier rom, reset settings, install cwm radios posted in xda) the phone will not get any signal strength.
The imei is showing... however the signal strength is 0dBm 99 asu... I cant even dial 911 it will say mobile network not available..
Any solution to this will be grately appreciated... i will gladly buy you a coffee or a ham burger...
Thanks,
How did you unlock your device?
Does this happen even with the stock ROM and whatever SIM you were using before you unlocked the device?
Do you have an appropriate network operator set in Settings -> Other -> Mobile network settings -> Network operators (automatic might work in this case), and a matching APN?
Just trying to get a sense of what might be causing this...
Maybe a hardware issue?

It shows the apns automatically once i put the sim card... like Bell or Rogers settings are shown in APN automatically....which means it reads the sim cards but doesnt register on any network... no bars... just a do not enter like symbol.....

Sorry please ingnore this as the serial number was changed when i installed cyanogenmod... when i put stock rom the serial number is back to thr same as the sticker behind the phone...
I'm not really an expert on this either, but I'm going to guess one of two things is going on:
1) The phone isn't as unlocked as advertised - perhaps something went wrong with the unlocking process and shot the modem firmware. You'd need to figure out what network the phone was originally on to figure that one out, though. (Which reminds me - what baseband is your phone running right now? You might try something else from here - and make really sure you're using a Canadian baseband!)
2) Something was wrong with the phone long before it was ever sold to you, be it bad hardware, a bad IMEI (stolen phone?), etc. - the whole description of "bought my phone from someone" just sounds suspicious to me when you put it like that.
Honestly, I hope it's a modem firmware issue (I think if it was something to do with the IMEI and the like, you wouldn't be seeing those strange signal strength numbers).
EDIT: Here's a fun fact: when I unthinkingly flashed the broken CM10.1 12/28 build this morning (broken in that it refuses to communicate with the baseband), I saw exactly the same strange signal strength numbers. This leads me to believe that you are indeed facing a trashed baseband and/or an empty IMEI number, so check those out!

You could fix your s3 ?? I have the same problem
Hi. I'll simply explain what happend.
I went by plane. I switch my phone on to airplane mode, but when I switch it back phone can't connect to my home network.
It detected networks and can connect to the internet but I can't make any call or recive it (the same with SMS).
It show Me the error message - Mobile Network Not Available or just simply Call ended after two beeps signal.
Show me yellow triangle on the top notification bar and message - No service, Selected network unavailable
I checked IMEI - it's correct
I used PC Companion tool to Repair My Phone - doesn't help
SIM card work well in other phone
other SIM cards - the same problem - not working (I even tryed SIM card from different country network operator).
Phone has no SIM lock
Back to factory settings doesn't solve the problem.
Any ideas what going on with my phone and how to fix it? Please
Model: D5503
Android version: 4.4.2
Build number: 14.3.A.0.757
So it did work before in your home network?
Or is it an issue with a new phone?
Sounds strange to me... If your SIM works in other phones, it can't be a provider issue.
I can't imagine that it is a software issue since it keeps happening after a factory reset.
If it's the hardware it is a warranty issue...
But maybe somebody has a suggestion for you.

I had some unusual problems with an inability to xfer data over the mobile network (as opposed to the WiFi) on my wife's Z1c, after both had been fitted with what seemed to be brand-new sim cards by the local T-Mobile store, and I found that in:
*Settings
*Wireless & Networks: More
*Mobile networks
*Access point names
...that she (somehow) had an access point name of "epic.t-mobile.com" as opposed to my APN of "fast.t-mobile.com"
So, I deleted that, and selected "create default APN", and fixed the problem.
There are other settings in that same menu, such as "preferred network type" that might be messing you up.
She could make calls and send texts with this problem, but had no internet unless she turned on WiFi.
But I cannot imagine what would be re-provisioned by switching airplane mode on and then off.
Perhaps you need to declare your sim card a dead parrot, and get a fresh one from your service provider.
This is pure speculation, I have no evidence or experience, just guessing at things that MIGHT cause such a symptom.
Hi Team,
I have purchsed a brand new Xperia Z1 from a retail store.
I am having problem with mobile network connectivity, its not behaving in normal manners.
Many times it drops network and many times it gets auto switch off in a single day and I need to restart it 2-3 times in a single day to make it work properly.
Many times it happens that its showing full network strength and when somebody calls me it says that this number doesn't exist, this is not a simcard issue as my sim is working perfectly when I use it in any other mobile.
I have already given it to sony service center two times and they use to say that softwer was required to be updated that's why you were having network problem but its not resolved yet.
Its is very costly mobile phone and as of now I can't afford to buy any new phone as I have spent my whole savings to buy this phone.
Can you please help me?
Thanks in advance.

Solution:
I struggled for 2 days to resolve this. And the solution was so simple. I resolved the issue accidentally.
Besides following all the recommendations (except the hardware part) on different online forums I was exhausted. Doing nothing, I started making a backup of my cell phone with an idle mind. And there I found an option to reset your network. I have Sony Xperia Z3 Dual. You should try this.
Go to Settings -> Back up and Reset
Scroll down
Go to "Network Settings Reset".
Then reset your cellular network. And bingo. It worked for me. I was able to make calls and use my cellphone in normal mode.
Please let me know if it worked for you. I can guide you for some more tricks.
Hey Guys
Got a Nexus 5X I need to fix for someone and I'm a bit stuck. Supposedly it happened out of the blue for the user without anything like being dropped etc. The phone when a SIM card in inserted never registers onto the network, it gets the empty outline signal symbol without any bars and shows "No Signal"/"Emergency calls only"
The SIM gets detected when I unplug/replug it in. I have tried multiple working SIMs as well without luck. The phone also does show the IMEI number and also the Baseband version so I don't think it's a problem with the radio software wise.
What I have tried is the following;
Flashed STOCK ROM over itself.
Flashed CUSTOM ROM on the phone
Flashed only the radio img over itself
Reflowed the board thinking the SoC might be at fault
What I don't know is at this point is it a software issue or hardware issue? There should be nothing stopping it from getting a signal as the phone isn't showing no baseband or no IMEI number. It just stats unknown network and not registered for network when you go into the About > SIM status
Anyone know a way of sorting this out? :fingers-crossed:
I also have the same problem. My 5X can detect the sim card but doesn't show any network. Hope someone can give a solution to this problem.
I am having a very similar (or identical problem). My phone detects the SIM card but shows the 'service state' as "Out of Service" and the 'mobile network state' as "Disconnected" Under the network settings it appears that the phone recognizes my mobile carrier and has the correct APN settings best I can tell. In my case I think its likely that I screwed something up when wiping the phone and installing a custom ROM. I think I may have somehow screwed up the EFS partition. I dont know for sure, but ive read that this can be the source of mobile connectivity issues.
