[Q] Can't send / recieve texts or phone calls - Web works fine.

Managed to get a HTC Desire for an absolute steal of a price as the seller had managed to forget his lock pattern and hadn't set up a google mail account to bypass the lock pattern. Having used Android phones before I knew that if I could just figure out the correct combination of buttons on startup I'd be able to reset the phones to factory settings and have a working phone.
So, I quickly bought the phone, figured out the "Power+Vol Down" combination and ran a factory reset from within that menu.
The phone restarted and I went through the setup and everything seemed fine, until I tried to send a text/make a call.
When I send a text message, I get the message sending failed error and it retrys various times before the phone finally gives up and stops trying.
When I try and make a call the phone just hangs for a couple of seconds on the dialing screen, beeps and cuts off (as though I have no signal).
I assumed that the phone had been blocked, hence the seller was selling it so cheap and he had come up with this story of locking it out, but after having a play I realised the internet was working perfectly and I had full HSDPA signal. Now correct me if I'm wrong but I'd have no sort of connection if the phone had been blocked by the carrier?
I assumed this was a software issue and have updated from 2.2 to 2.3 but still the same issue. After updating, I've also realised that I am unable to change network carriers (I'm on TMobile and they now share networks with orange).
My sim works perfectly in other phones and if I put another sim in the Desire, it still has the same issues. The phone is locked to TMobile (not that I think that would matter), running the official HTC 2.3 Gingerbread release and as far as I'm aware my APN settins are all okay.
If anyone could shed any light onto what is going on here, and hopefully to a fix then it would be greatly appreciated
Thanks in adavnce

[Problem] No network/signal

Hi
Just got my new Samsung Galaxy Nexus today, but it cant find a network and have no signal.
I have tried to search for network in settings, but it comes up empty.
In the "about phone" page under signal it says -113db and 0 asu (varies a little bit, but not much)
I'm in Norway using OneCall, on the Telenor network, but the phone cant find any network.
The simcard works fine in other android devices.
The phone was sold as unlocked/simfree.
It says "onecall" on the bottom of the notification bar when I pull it down.
There are also apn settings for my simcard (looks like they are read from the simcard)
Wifi works great, and I can't see any other problems than that it cant find a network, but that is kind of a big problem since it is a phone!
I have rebooted multiple times, three factory resets, and tried with another simcard, but no luck.
Anyone have a idea what to try? should I try a custom rom? or do you think its a hardware problem?

I just saw "Telenor" when I searched for networks, but when I tried to connect it said it couldn't connect, and now I cant find it again.
Seems like I just have the worst possible antenna! (or radio?)

What type of phone did you have previously? Maybe you need an updated SIM card?

A new SIM card has solved this type of issue for quite a few people so give it a shot!

But it works in other phones like the HTC Desire and the old Hero.
I just drove into town, and I got a few bars, could make phone calls and so on.
But back home it still cant find a network.
Which leaves me to believe that the antenna (or the radio) is bad.
Do I have to root it and install a custom recovery to install the stock rom again?
Or is there a "rescue" solution? like on HTC devices.

Works fine here. Test a custom rom or another radio or something.. If it not works go back to stock and return it. I bought a HTC once with a bad antenna.

same problem
what did you end up doing kjetil84? I have the same problem. at home I have like no signal, but other places I have a litle. I use Talkmore witch also uses telenor.
an update would be great

That happened to me once before, try doing a factory reset.

still a problem
Just tried a factory reset, and it did not help
I love the phone, but at this time its not usable for me

[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?
Sent from my SGH-T989 using xda premium

@#11 That reads like gibberish to me
@#12 I think I posted a fairly extensive report on how I fixed this...?

[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] SMS immediately failing, due to phone setting

Hello all. Today I was playing with my phone, just doing some tinkering, running a ROM called Xylon (4.2.1) in the phone settings. You know, where you hit *#*#4636*#*# or something rather. Now I changed my network type to GSM, (or something rather) but saw I only got 2G, so I switched it back to WCDMA preferred, and left. (Honestly can't remember if I changed something else)
Now, every time I try and send a text, it says sending.... then it fails. All the time, to any number. Which is obviously annoying.
So I went ahead and flashed another ROM, clearing all my data, cache, dalvik etc. However this problem persists. Even using a different SMS app. What should these settings be? I haven't touched them after flashing another ROM.
I know I'm a goof, but I rely heavily on SMS, and I was just looking for a way to have it stay on HSDPA more often instead of 3G. Now I want to revert to stock. Many, many thanks for any help at all

Here are screen shots of my settings. Again, I'm pretty desperate, and need some help

Okay, I think I got it. My SMSC number was missing. This is basically a message center number, that is specific to the carrier. I remember seeing it back on my Blackberries, and on my old Gingerbread powered Captivate, but the settings are obviously different from ICS and above. (ICS has been out for so long, that I forgot)
So, basically you do this, go back into the settings that I showed you in the screen shot above. Leave everything disabled, and have the network on WCDMA
Use this tutorial http://wiki.cyanogenmod.org/wiki/SMSC_Updates
Fido's SMSC is +15149931123
hit update and reboot
If not, try 07915141991321f3
and reboot (same thing, but it HEX)
hopefully none of you have that problem
EDIT: Girlfriend confirmed, that was the problem. Now the phone works like a champion
