Phone Signals - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

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?

I bought this phone from someone and stupid me didnt check at the time... i have tried every sim there is present in toronto, canada... and still no luck...

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.....

How to find that out...

One thing that i have noticed is that the serial number from the phone behind the back is not the same as the serial number shown in status settings of the phone....

i really would not know it's not really my area i think smelenchuk might help better. Sorry i couldn't be more help.

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!

[Q] Your SIM card does not allow a connection to this network

(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).

If you want help, you need to tell us more details, such as what software/firmware version you are using, network carrier, what actually happens when you get no service, if it's rooted, etc.
Basically, the more information, the better.
Anyways, I have that random no service with the Australian Optus network, even though it says on the phone that I have full bar reception. Sometimes it's just the network.

i got to bed with signal and wake up to no service,
when i try to manually chose the network it says im not allowed?
i have to reboot/ or chose airplane mode and then put airplane off to get it to work
i normally have my network set to gsm only and theres good signal where i live
its happend twice at home, once when i was in a diff area where i suddenly got the enter pin code prompt
has anyone had luck wit this?

"Not allowed" suggests a SIM problem.
Either the SIM has gone bad and you need to request another one from your network, or the SIM connection on your handset is dodgy.
The SIM governs what you can and can't connect to. If it's not allowing you to choose a network then it's not reading the information from the SIM properly.

maybe that will fix the problem,
thats my next step.wait for the ota

Stuck on EDGE (cant use 3g - 4g higher connection)

Hey guys. Firstly im sorry about my poor english.
I have a T-mobile T999 s3 that has clone(fake) imei. (Its imei is copied from another old mobilephone)
It is working good with stock rom. But stock rom doesnt have turkish language in it.
I tried to install morelocale and language enabler apps from market but it didnt work.
Then i installed "CyanogenMod 10 Nightly Builds for SGH-T999" (it has turkish language) works good but i cant use 3g or hspda or hspda+ or 4g connections. (i only need 3g cus there is no 4g in turkey now) i tried to choose Only WCDMA-LTE in menu and i lost connection.
So i can only use Edge (2g) connection and its like turtle!
I read solutions of this thread but i didnt understand anything... I think my problem is different
(Note: I cant turn back to original imei because its blocked and doesnt work. so I have to use cloned imei)
(Note 2: Imei number is not 0)
(Note 3: tried another custom roms but didnt work)
What i have to do? Waiting for your helps. Thanks!

yes the location is same and i use same operator so i use same apn setting of my operator. am i doing wrong? what i have to do if im wrong?
it was connecting by 3g and higher speed before injecting fake imei. (with same apn settings) i think injecting imei with box causes that.
i dont know about these boxes that writes imei to mobiles. i just send my mobile to a technical service for imei.

I'm not sure about a cloned IMEI but if youve (re)inserted a new IMEI and lost data on the network and the IMEI isnt being blocked, there is a process around that can help to clean QCN file from your NV backup (extracted with QPST) you could PM Motodefier, and he may be able to assist. He helped me out after my 4g LTE was lost when I manually reinserted my IMEI (bit not cloned) and got me back up and running and saved me a lot of hassle, he wont ask for it but make sure you drop a donation if he spends some time on fixing your issue.

[Q] D851 LTE europe doesn't work

hello every one.
My lte doesn't work. I already test with the rom paranoid and CM.
I m from morocco our 4g is new and i think is the same as the europe 4g (lte).
Do you have any idea ?
Pls help
Thank you for your time
up
Help pls i need to flash modem ?
Which carrier are you using in Europe? Are you roaming from T-Mobile or have you purchased a different service/SIM card in Europe?
Also, what country are you in specifically?
There was a guide somewhere on XDA regarding Qualcomm processors and band unlocking using QXDM (LTE) and QPST (GSM/WCDMA) though I forget the exact name. I believe there was also concern that it could damage antennas. Also I have no idea if it actually works and mucking around in the NV RAM space is very risky. I would not advise it.
Is at least the GSM service working? If so, is it really that bad that you need LTE? Personally I would leave it at "oh the gsm works, I'm good". :good:
Depends on the carrier you are using, is your phone unlocked? I would assume that it is since your can receive gsm signal.... Anyways, what you would want to do is check your network's APN and check our phones APN settings and add the 4g/LTE APN settings to your phone manually... Then restart your phone and try again, make sure you select the apn after adding it so you know it's active. Try that. If that doesnt work, then go into your APN settings again and just do (reset apn setings) or something along the lines of that which resets/restores your apn settings back to normal/default.... either one could work, try the first one first ofc!

As stated already , the signal could be weak in your area. Type in the dialer key pad ##3282# and you can also look to make sure all the bands are enabled on your device. I don't see why they wouldn't be though. A handful of users have stated bad connectivity with the M9, but that's on the sprint network I have been reading about.
at ##3282# it say only OK.. nothing about enable bands and i tryed sim of my friend (vodafone 4g) he have m8 and 4g working... on my m9 doesnt..

I have same problem with my M9+. In Manchester Area UK
I had perfect 4G with my old M8 but with new phone only 3G!!
Let me know if you get any answers. HTC and Vodafone couldnt help me either.
Check access point names, make sure only one is listed and selected.
Go to networks and search for network, click automatic.
Open the connectivity selection and make sure that the scalable option is chosen (2g/3g/4g)
Are you using one Base with the wrong firmware? Make sure they match up.
Find a friend on the same network or shared network and see if they have 4g in your location.
Test the sim in another phone.
Call network to check for issues in your area and or if there is an error against your account, may need a new sim if that one is old.
Test in major parts of the city center next time you're shopping..
Perform a speed test to see what speed you're actually getting, hspa is up to 20mb, 4g AFAIK is around 60mb, I've had 48 before. Anything over 20 could be considered 4g, you will very very rarely see a 3G tariff go over 19mb, which is the most I've ever seen.
Good luck.

I have the same issue with the M9. Couldn't find an answer for this problem. Even tried opening lte bands as listed here but no luck.
The thing is that I used to get LTE where I am now, went on long holiday and can't get it to work again so no idea what's up.

That's a network issue, get a new sim and speak with your provider. Try the things I listed too

I tried my sim with my wife's iphone and i got 4g without any problem. It's not a sim issue. Whatever the problem is, it's with the device (hardware, software, settings). I remember it also took me a few weeks after getting the M9 to get a 4g signal, but then one day it just appeared so there's that to add to the mystery.

Reset your network settings mate, set to manual then back to automatic.
Make sure you actually catch the network on manual first before manual. You will find it, it's just a case of going through the motions.
Also click menu, reset to defaults in access point names.

1. How do you "reset network settings"?
2. set to manual - you mean in 'Network operators' menu select 'Search networks', select my network, then go back and selecting 'Select automatically'?
3. What do you mean "just a case of going through the motions"?
4. Should I reset APN at the last step or at the beginning?
I'm trying to understand your steps as clearly as i possible can because this no 4g issue took a lot of time and effort from me and it still doesn't work. Any help is very much appreciated.

I am trying to help you.
There are no steps it's just a case of trying everything to do with the network. If what you say is true and you've literally just had this issue occur out of the blue then it has to be a difference on the handset, especially seeing as you have tested the sim in another phone and it works.
Reset to default is with apn, doesn't matter when you do this just reset them, make sure it's checked and cycle mobile data on and off.
Clarify that your device is set to 2g/3g/4g within network mode (I believe it's called)
And I was referring to setting network selection to manual within mobile network settings, then choosing your network, then researching and selecting automatic.
The path is: settings / mobile data / network operators / search networks, wait for yours and select it, cycle mobile data (turn off then back on) if that doesn't work, switch back to automatic.
Reboot your phone after making changes, perform the full shut down method instead of the restart or power off methods, it's power and volume up AFAIK, hold for 10+ seconds, might be 15.
Going through the motions refers to checking anything and everything which influences the network, one of these setting will get it working..
Might be seen as overkill but a factory reset (if it's not been tried already) good luck.

I know you are trying to help me, and I very much appreciate it. Truly am.
I tried doing all the steps you listed, but no luck. Even tried at some point to force lte only in 4636 screen but that resulted in no signal at all. Trying to manually select a network in that setting only gives me the other 2 networks that work in the area but not vodafone which is what I use.
As a complete overkill I RUU earlier to the new 2.11.617 firmware without signing into my google account or restoring anything, and still no lte. What I did saw however, in the select network screen, was that next to my network, it said 2g/3g and next to the other 2 networks here it said 2g/3g/4g. Obliviously I can't select them as it's a vodafone simcard.
I added here SS from LTE discovery app while i was on 'lte only' mode. You can see signal is there but it cannot connect.
Any wild ideas or suggestions? I'm opened to try almost anything
Just out of interest, have you tried a different sim card? I know you said that your sim worked in another phone but I'd still be tempted to contact voda to get a new sim and to see if everything is set up on a network level, you may have to tell via that the issue is persistent in different phones or they may make you pay for it.
Also, might be something to do with the association between your phone and your sim. I once had a sim that blocked my missus, she could call me but I couldn't call her, no active diverts of any kind, I could call anyone and they could call me, got a new sim and it was sorted. Very strange, but anomalies like this do occur.
Have you got any mods or are you at stock at the moment? I know you said ruu. Oh and lol click thanks BTW.

Well the thing is that my wife's sim card in my phone only gets 3g. On her iPhone it's 4g. My sim card in my wife's iPhone gets 4g. On my phone only 3g so it seems like a very specific problem with my device.
Shortly after ruu I installed viper 3.5 without any mods..
Can it be that my device is somehow blocked by the network towers or something of that nature?
Maybe a hidden setting somewhere that blocking the phone's 4g capabilities? This is getting ridiculous..
Thanks for your help mate. Can't believe I forgot to press the thanks button [emoji2]

No worries fella
If you've already tried another sim and it's still not happening, the firmware matches the rom, your sim works in other phones with 4g. Then I'm really not sure mate..
Give Lee droid a whirl that's what I'm using at the moment.. A simple but great rom..
I'm pretty much out of ideas now, if all of the above has been checked then it's something that I'm not aware of.. Sorry mate..
for the record it is a weird one, something should have got it working by now..

Are you in a position to be able to return the device? Just in case

I can't return the device as it was bought in the states and I live in Europe at the moment.
I think I will try to change my sim card for a new one just in case, and will change back to stock 2.11.617 for a couple of days to see if that can make any difference.
Will post an update if i will have one.

Good luck fella, hope it all works out for you. With it being bought in the states would the band frequency of the device make a difference? Just spitballing there. Good luck..

Yes it would. He probably bought a cdma and has to have the correct bandwidths unlocked.
