[Q] [help please] Your sim card does not allow connection...

Hi guys,
ok... I have an HTC desire... originally on Virgin Mobile and now unlocked. I'm an O2 customer...
I have rooted and installed the Leedroid rom... originally at version 1.8b. Everything was fine.... until I had a corruption on the SD card.... which I fixed when I got a second following a couple of days of "mounted read only." A day or so later, I lost connection to the O2 network and have been unable to regain it, despite several ROM (I'm now running Leedroid 1.9) and radio reflashes.
I still have access to wi-fi, gps etc.
I have tested my sim card in another phone (all ok) as well as other sim cards in my phone (doesn't work.) I have also swapped and tried another O2 sim.
The phone detects all the major networks... just won't let me connect.
The error message I get when trying to connect to a network manually is "your sim card does not allow a connection to this network"
I've obviously checked that the phone isn't IMEI blocked etc. I've also tried the sim unlock from the fastboot menu, the switching on and off of the radio, airplane mode... lots and lots of stuff.
I really am at my wits end with this issue. I love the desire... but it's obviously of no use to me without the phone element!!!
Can anyone please suggest something to solve this problem???? Could the corruption of the sd card have caused this in some way, despite several rom/radio reflashes since? I really want to stick with the desire, but at the moment I effectively have a £400 brick....
Thanks in advance for any help you might be able to provide.....

Firstly this is not a development issue, its a question.....
But anyway, when the phone is telling you that you cannot connect to the network is it allowing you to enter an unlock code at all? Or have you ever "unlocked" the phone in the past?

You're right Lenny... apologies for creating the thread in the wrong part of the forum.... perhaps a mod could move it....
Yes... the phone was unlocked from Virgin mobile prior to me buying it [from ebay.] I didn't perceive this to be an issue, given that I actually had connection to O2 for a day or two before losing it...
No... the phone/sim is not asking for a code when I attempt to connect.
Thanks,
Shep

and did it stop letting you on randomly, or did you do something immediately before?

Nope... completely random. I was in a poor reception area and initially put it down to this... but then it never returned and I'm now back at home having had zero connection for a week.
I think that my repair of the SD card was after I initially lost connection. But as I said, I'm not sure whether the SD card corruption is a red herring.

Call me sceptical, but I doubt you would of been able to check whether it was on the IMEI blacklist or not unless you worked for a phone network.
It's not public knowledge and someone working for O2 shouldn't have told you if it was or wasn't.
Also, even if they did and the IMEI listed on the handset is NOT blacklisted, as was possible with WinMo devices, you may have unintentionally changed the recorded IMEI on the handset to one that IS blacklisted - unlikely though I'll admit.

the sd card should not have anything to do with radio.
Go to dialer and dial *#*#4636#*#*
then press phone info

done.... what info do i need to post?

try to go down the bottom and press the "turn radio off" button
then when its turned off try to turn it back on, then see what happens.

Just done it and no changes.
Did it several times between reflashes too... not so much as a flicker...

No idea then, unless the IMEI has been blacklisted.

Ok.... thanks anyway.

Any luck getting this to work? Am in the same situation - t-Mobile unlocked Desire with a 3 SIM?
Edit: I have intermittent reception/connection to 3 now - I did a lot of recovering/trying RUUs which would partially load on Win 7 then just disappear...assume they should have done something more than that. What seems to have helped - and I partially had this problem in my Nokia E65 - was to place a piece of paper (SIM sized) behind the SIM to 'push' it onto the contacts. Well, maybe it was a software issus but it's now my luck paper and I'm not removing it!

Gone again. Very annoying.
RUU'd to RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00.32U_5.11.05.27_release_159811_signed (unbranded 2.2) and still no luck.
Any ideas?

[Q] Desire Z - no data or voice connection??

Hi all,
HEEEEEEEEEEEEEEEEEEEEEEEEEEELLLLLPPPPPPPPPPPPPPP!!!!
I recently acquired a Desire Z which I was told was 'locked' (to O2-UK) and 'blocked' (turned out the previous owner had got the pattern unlock wrong too many times and it was asking for Google account details). I did a factory reset and then put my T-Mobile UK SIM in the device, to confirmed it's locked status. I noticed that I got a GPRS connection, but no voice or 3G. I assumed this to be a symptom of the lock, as my original Desire came unlocked, so I thought nothing of it.
I used the gfree downgrading/unlocking/s-off/superCID rooting method as described in http://forum.xda-developers.com/wik...sion#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD, verified with gfree_verify (all OK), and installed CM7.0.3...
Still no voice/3G! The handset still intermittently gives me GPRS, but there's no discernable rhyme or reason to how or when this happens. I've tried network auto-select and manually selecting, but get 'Unable to connect to this network at this time. Please try again later.' I also occasionally get something along the lines of 'This SIM cannot access the network selected' (I didn't keep a note of this error, so that's paraphrasing).
Tried a Vodafone UK contract SIM - this gives no connectivity at all and the same error messages as the T-Mobile SIM. I'm waiting for an O2 UK SIM from a friend tomorrow to test. Both SIMs are fine in my old Desire.
I've done everything I can think of - gone back to stock, S-ON, default recovery, basically got it back to pristine factory settings, different firmware/radio versions, and it's made no difference. I've looked through the threads at http://forum.xda-developers.com/showthread.php?t=835673 and http://forum.xda-developers.com/showthread.php?t=805024 as these seem to be addressing a similar issue, but my problem seems to be unique in that NOTHING seems to get me a GSM/3G connection. (I'm also not so hot at GSM interface programming... )
I've got the logcat output from device boot through to the appearance of the lockscreen; however it's too big for this post so it's at pastebin (probably complete overkill, but I don't konw what I'm looking for): http://pastebin.com/gn578Yfw
Any help will be massively appreciated, and thanked with beer where possible.
Finally - apologies for length, just want to make sure I've covered all that I've tried so far.
Thanks in advance,
Steve.

I think, that the previous owner, perhaps was not the previous owner. It's probably been stolen or found. the actual owner has notified his/her network (o2?) and have gotten the phone blocked. Nothing you can do i'm afraid, it will still work outside of the country.

Meh, you're absolutely right; CheckMEND and Mazuma have both confirmed today that it's blacklisted.
Rubbish. Still, that's what I get for buying a phone off gumtree and not asking the right questions, I guess.

[Q] T-989 - No data network. Mobile Network State: Disconnected

Hi there. I own an unlocked, rooted t 989 Samsung Galaxy SII which I bought in the US. I recently moved to the Netherlands, and got a new simcard with Vodafone. The problem: I can't get my data to work.
I have tried (almost) everything, so prepare for a read. Here's the list:
- Sim card is fine, I tried it in a old phone and 3G pops up instantly
- Rebooted, pulled battery, turned mobile connections on/off, handpicked network, etc, etc, all the basics.
- Got the APN settings from Vodafone. Tried them manually, resetted them, automatically, turned it on, turned it off.
- Going online through Wifi works.
- Under settings-Status it reads under Mobile Network State: Disconnected. But I know that the phone detects the network correctly. It can distinguish between UMTS and GPRS here.
- So there seems to be no trouble with the phone being incompatible with the network. I read online that other people had NO trouble using their T989 in Europe.
- I tried inserting my old American pre paid T mobile sim card and turn roaming on. No luck.
- A lot of other people with the same problem tried to link it to Easy Battery Saver. I tried updating, uninstalling and going into its settings to find out what it could be, but nothing.
The last thing I can still try is to factory reset, unroot and try to get the phone to its most original state and see what it does. But before I triple wipe all my contacts, pictures, apps, etc, I want to make sure I did absolutely everything to try and fix this beforehand. Being a noob here, I can't post any links but I trust you I tried.
The people at Vodafone are of no help whatsoever. I hope you geniuses could help me any further.
[Edit] And sorry for posting this in General Chat. If a mod could move my question to Q&A I'd be most thankful..!

I am having the exact same damn problem! it started with being unable to send a simple text message yet having data. now it says it is searching forever

Try flashing a different radio/modem then an american one?

@decko5 Nice to see I'm not the only one, but that doesn't help us yet .
@doug36 Besides the fact that I'm running a stock ROM that should be compatible with no issues, I'm not sure how I'd do that. I can flash a separate part of the kernel? That sounds like a very tricky thing to do.

It's actually pretty easy. You can flash most radios via ClockworkMod Recovery. I couldn't find any threads with a list of Galaxy S-II radios here on XDA, but I found one over at RootzWiki for you. http://rootzwiki.com/topic/2725-radio-samsung-galaxy-s-ii-radios-updatezip-updated-20-aug-2011/
Just find the corresponding one to your geographical location and carrier (Google is your friend) and follow the steps.
Good luck and hope it helps!
(p.s. you should definitely look to see which radio you currently have so that you can download a backup of it before you go flashing radios.)

Thanks for that very helpful post! I've raped and butchered Google, but I'm still having trouble finding out which modem I should download. There seem to be so many and the post on RootzWiki gives no guidance to which is which. Any wisdom on this? I'm in the Netherlands, so Western Europe, on a Vodafone network.
By the way. I fully wiped my phone and installed Team Kang's Juggernaut 5.. No luck, same problem. What I found really, really weird is that it was instantly in Dutch. (Which is ok, I speak Dutch) But I don't remember ever selecting a language. How does it know? Besides, I'd rather have it in English .
What I did find out is that I'm still using a old firmware, UVKID, instead of UVKL1. So I'm restoring back to my previous ROM and trying to update. I'll see what happens. If that doesn't work, I'm going to restore my phone to stockest of the unrooted stocks and try and update.
If that doesn't work, I'll have no option but to send the phone to T-mobile.
I'll try the modem update as soon as I understand what I'm doing . But it does sound promising. Thank you so much for your help, it's greatly appreciated!

Hi guys,
I've updated my firmware to UVKL1, still no luck. Anybody who can tell me which radio I should try on this Vodafone network in the Netherlands?

I am from India and had faced this similer issue with many of my android phones specially with captivate and infuse.......Here what i always did to connect data network.
Just uncheck the use packet data network box in mobile network settings and try to move out from that area (say u are in ur office and going back home) and check the data in settings.
This thing has worked for me always, I don't knw if its related to the OS or to the network provider but this has helped.
Have u tried any other network sim card on ur phone ?

An update for other people that might be looking for a solution in the future. It turns out to be a clear Vodafone problem. I tried a different simcard from a different network (both T-mobile Netherlands and KPN), and they instantly worked without any trouble.
I went back to a different Vodafone store in Amsterdam, and they were much more helpful than the first one. The sales guy told me he had seen the same problem with AT&T iPhones on the Vodafone network.
I called Vodafone, and they have been very nice to me. But they haven't found a solution yet and are looking into it. They see me registering to the network, granting me access, but still my data doesn't work. They've also told me that they will let me cancel my contract for no cost if they don't find a solution.
So problem remains unsolved, but at least there's some light at the end of the tunnel. I was close to buying a new 500 dollar phone... Americans going to Europe: Beware with getting a Vodafone simcard. Sorry to the Vodafone guys, but as for now, that's the status.

So to give closure to this issue (I always hate it when people fix their problem without telling the interwebs..)
IT WORKS!
After an initial terrible experience at the Vodafone counter, the headquarter tech guys have really been great to me. So it is indeed a Vodafone problem. American phones always give them a headache. They don't know what causes the problem exactly, but they do have a fix. It turns out that when logging on to the data network, American phones (AT&T iPhones, my T989 SGsII, and some other Android devices) sent some gibberish along that make the Vodafone server go cuckoo.
The solution was, miraculously, to sign me up (for free!) to the WiFi hotspot service that Vodafone provides, and then logging on to a different APN, being: office.vodafone.nl in my case.
Hope this helps anyone who's having similar issues.

ok the issue here is that some of the t989 are vodafone and some are USA network , now the other solution is that you flash with command prompt which there is a link to that tool im going to upload from the link i got it from . its also a clockrecoverymod , but this 1 asks you for deleting data user on the device and also resets the network includes USA/overseas though if your not customed roms
or any hacked roms , after flashing this device your basically removing any unwanted apps and cache that are hidden during network searching will be fixed bugs , put the simcard in slot but make sure that is a 3G/4G accounts, than its going to reboot the device automatically , it should be searching for service and also will be a circle with a slash on it where the service bar usually is , just wait about 1/2 hour to an hour maximum time let it do its thing , ok whats happening now to the phone is that is thinking with android network with usa and overseas market apps comparing both carriers network also gets the proper address for the custom rom or original kernel, froyo either 1 will get the correct network address and / VPN / and also will be adding both T-mobile/AT&T choose T-mobile dont go for AT&T cause it will research network configuration plus the phone its not unlocked for both its just a network passby to get correct WPN/VPN/clockworkrecoverymod .

Where is an fix?

[Q] suddenly can't see any mobile networks - Baseband "unknown"

SYMPTOM: can't see any mobile networks
BACKGROUND: I've been using htc one x for a month now. Initially on three, but their signal was unusable at home, so sim-unlocked and switched a couple of weeks ago to giffgaff ( a virtual network on top of the UK o2 network).
All has been fine, until today. I sent a few texts & calls in the morning, and mobile data was working. Since then, I can't see any mobile network.
wifi is fine.
Search Networks pops up "Error while searching for networks" and finds none.
No software changes of any sort since last successful call. No changes at all today, at least until I tried to diagnose the problem.
Running stock rom, with the WW update of a couple of weeks ago (1.28.771.9.CL56522 release-keys) -- neither S-OFF nor unlocked bootloader.
Nothing obvious to me in the normal or radio logcat logs.
The only thing I did after the last successful call was to run sensorly to try and map a trip. I've used this before without any problems. It got no connection but I thought nothing of that. I've since uninstalled it just in case it could somehow be interfering with the radio.
THINGS I'VE TRIED:
No, the airplane mode isn't on, and mobile is. I've toggled airplane from settings and power switch, many times
recreated the APN
checked other phones - yes there are a number of networks visible
tried the original o2 sim - same problem
safe mode
cold boot
reboot, reboot, reboot
obviously I haven't pulled the battery...
turned off wifi, in case it was somehow interfering
HTC diagnostic tool
factory reset
confirmed imei is not blocked
Any ideas? Bearing in mind that I'm looking for something which can happen spontaneously.
Interestingly, while writing this I've just noticed that Baseband version shows as Unknown. That worries me - is it possible that my radio partition has spontaneously corrupted itself?
I did speak to 02 support - they said to take it into a shop for warranty repair. I don't want to try a custom ROM just yet -- not when I might have to use the warranty. But is there any way to force it to reinstall the stock rom (preferably not involving windows)?

I have the same problem as well and flashing custom roms did not solve it for me. But for me even the IMEI number is shown as UNKNOWN...I haven't done anything special to get this issue, one day when I woke up the phone could not connect to any network.
I have tried a lot of different methods but with no success. I don't think we can do anything about the baseband without S-OFF.

If a hard reset fails, then it's time to think about returning the unit. Either get a refund or get it replaced.

This may be irrelevant; but I've had this happen to me on my GNexus. I solved it by going back to stock and it just fixed itself overnight.....

my HTC One X did the same after about 2 weeks. Gave it back to supplier, waiting my replacement.
Even tested with a different SIM card, did a hard reset. Problem stayed the same.

Im curious did any of you find a resolution to this? it happened to me a while ago but yet to fing a solution. HTC refuse to fix under warranty because it is unlocked.. i am currently waiting for the next official update to see if that fixes anything but the way things are looking that could be a while..

It sounds like a fault, probably the radio chip has just stopped working, no software is going to repair that. If it was a software problem, there would be hundreds or thousands of people all having the same issue.

[Q] Disconnected because service is unavailable

Hoping someone can provide some direction. First and foremost I am not a HTC savvy so although there are a few threads here about the same issue none of them relate to me as I have not rooted the phone nor flashed to custom ROMs or anything to that nature. I am simple user of the phone... Now.. to the topic.. so I bought this phone for my brother in law last year as a birthday present, and at the time I had a working phone so I didnt put my mind too much to it.. but I did liked the phone very much. Two months ago, I decided to purchase one of these, so I bougtht an HTC ONE X Phone S720e Android 32GB 8MP 3G WiFi GPS Bluetooth Unlocked White. I don´t recall what versión of Android it carried at the time but looking at the specs it should had come with Android 4.0.3. After loading it up, transfering my files on to it and loading some basic apps, whatsapp, email, Skype... it off coursed asked for a software update two times which I went ahead and did. The last one it installed added Android 4.2.2 and HTC Sense 5. It was working fine, layout changed considerably... now after doing another of the updates to applications and software, specifically the transfer files update it suddenly quit recognizing data services completely. I though it might be something with the micro sim, so I tried testing a couple of others, it didnt make a difference so I decided to back up my contacts and information I had on the phone and did a Factory reset. It wipped it clean but issue remains the sames, it is unable to even recognize the sim card is missing and when I go into settings I see the message Disconnected because service is unavailable.
Reading online, saw a few folks stating that this situation was related to software updates.. so I was wondering if I could get some help on how to get this fixed. Not sure what to do, downgrade to 4.0.3 or how could I get it resolved so appreciate some direction here.

If you go to settings - about - phone identity, does it still shows the imei ? Seen many people here having their imei gone from their phone and becomes an iPod since we can't write it back. Tho you are on stock, so better send it for repair.

It shows up as unknown actually... is this a software related issue then? Im concerned about the other phone going through the same situation... should no updates be installed to it then? That makes it fairly useless and might prefer to send it back and try to get a refund instead.

same problem for me, still wait for fix
