(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).
IPosting this more as a FYI from my recent experience with my Verizon LG G4 phone using over seas (Vietnam vs. originally in the U.S.). The phone is currently rooted with firmware VS98610BB (10B) with Android 5.1. The phone is no longer on Verizon Wireless (paid off device and service cancelled). Earlier in the day, my LG G4 experienced an abrupt "SIM Disabled" followed by "No SIM - No Service". I was in the middle of surfing the internet via Viettel's 3G (Vietnam cell phone carrier) when I lost the ability to use the cell phone service. At first, I thought my phone was suffering stability from the drops and banging that happened to the phone recently, however I believe the accidents were negligible due to a soft transparent TPU cover I have on the phone. I then thought that my SIM was probably banned, blacklisted, or blocked from the carrier. I tried restarting the phone. Doesn't work. I removed the battery and reinserted the battery and powered on the phone. Still doesn't work. Finally went to a local Viettel retail store and the representative checked the SIM. It was working in her phone (phone call made to the retail store and phone call made to the phone having my SIM).
I made further searches online to see what other things to try or the possible issues. Saw some may have hardware defects, but in order to eliminate the SIM reader was broken, I decided to whip out the Verizon's SIM to try. The Verizon SIM verified that my phone didn't malfunction. So I was going to try the next solution is to mask the IMEI to verify my SIM was blocked on Viettel's network. I took out the Verizon SIM and stuck in Viettel SIM. To my amazement, Viettel network was picked up again.
I did notice that while I was at the Viettel store, my APN entries were wiped out or erased somehow. I reentered all the APN information but it didn't help while at the the retail store.
Well, the conclusion is: swap SIM into the G4 to see if it resets the network and SIM information, then stick in the SIM you're using.
I hope this is helpful to those who experienced the same issue.
Ran into a similar problem as indicated in the above post (no carrier signal found) with another LG G4 under my care and this time, trying the above workaround did not work for the second LG G4 phone. It appears that something must have corrupted the system files or other files. What I additionally did was cleared out all of the credentials (Settings/Security/Certificate management/Clear credentials). Also, I wiped out the cache by performing Power+Volume down keys on boot up to access boot options of wiping cache (rooted phone). After rebooting the phone one more time, everything went back to normal. What bugged me was that the phone was charged up to 80%. After another reboot, it is now at 100%. Strange. Another thing that was strange was when enabling airplane mode, to disable it from the settings menu was grayed out, i.e., cannot switch off and on. However, the quick settings still worked. But everything is in working order now. This leads me to believe file corruption has happened to both LG G4 phones. Even the APN list was wiped out.

what rom are you using? stock or custom?
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.
hi everyone, i have a lg G7 EMW for almost two years now. as said my phone its an EMW, although I use the EM variant ROM for more than a year because of the lack of updates. never had any issues before.
some weeks ago i had to make a call and noticed it was not working, at first i though it was a cover area issue with my carrier, since it was a place a little far away.
but in the following weeks i started noticing a lot of messages saying 'a number called you and did not left a message' and them i realised that the phone actually never ringed, so i started making some tests and realised it was not making or receiving calls.
i cannot acess all the settings in 'call settings menu' it return me an error saying "network or sim card error" but my 4G internet connection and SMS in the other way, works fine.
I already tried my SIM card in another phone, It worked normal. then i tried another SIM in my G7 and it has not worked also.
i have also tried to go back to my country open rom in a fresh install, but nothing changed.
yesterday after receive a cell broadcast notification, it worked for a short period an them stopped again, so i suspect may be some problem with the network, seems intermittent somehow
have any of you faced similar issue or know any solution? is there something i can do in service menu to see if its a hardware problem?

There were networking changes, so you need a sim card that is compatible with these changes.
If your SIM was purchased two years ago, it may not be compatible.
Just contact your phone provider, whoever it is, and ask them to sell you a compatible LTE Sim card. I had to buy one from Net10/Safelink for 99 cents, because the one I bought two years ago from Best Buy for "Net10" was not compatible with the new changes. All phone service providers should have a "buy your own sim" program, so just contact them for it.
check all necessary information in phone's settings about section.
Is any information missing there or blank?

i can give that a try but i'm not sure, my LTE and SMS seems to work normal, it is only the calls the problem.
the other SIM card i tested on my G7 was from a different carrier and the problem persisted
also my sim worked normal on other phone (Moto G5 Plus)

Call your carrier and ask them if they are using VOWIFI and VOLTE for their calls now.
The phone falls back to 3G mode on calls.
If the SIM or the tower you connect to is not provisioned for VOWIFI/VOLTE, the calls will use 3G.
if the tower is provisioned for VOWIFI but your SIM is not, then the calls will fail. SMS will not fail since that's LTE already.

This problem arises when particular phone has lost phone identification numbers such as S/N, IMEI SV and mainly IMEI. if it's the case then you must try flashing latest stock firmware for you model.
