No Network to call but 3g works(Solved by fluke)

Got a new problem with my G1, basicaly I used my phone placed it in my pocket went out then when I next checked my phone I had no signal, I didn't take too much notice of it. When I got home and also there I had no signal, did the obvious rebooting, no joy. Then I did a wipe restarted the phone, still no signal now this is the strange part I had 3g because my phone let me sign in also started syncing my phone contact. I can browse on the net also download from the market but when i dial a number I get the message Not registered on network. So when I went to settings/call settings/network operators/available networks clicked on t-mobile it says Your SIM card does not allow a connection to this network. Then just for fun try it with the other network operators same message. Also my sdcard was reformated.
Then I downgraded to rc7 (dreaming.nbh) rebooted no call signal but can browse and use market so I've updated to android 1.5 ota still no joy any ideas I planing to take to a t-mobile store let them check it also has anyone else had this problem before.

Sounds like a problem with your network, not with your phone. Either that, or your SIM card is fried. Assuming you're on T-Mobile from your post, you need to contact them for a new SIM card (you can do this inside any of their stores.)

It really may be the SIM card or the SIM card reader in your phone (more likely the SIM card) it may work on another phone
try cleaning the contacts (the ones on the phone, not the ones IN the phone) ?

Call customer service and ask them to take you off whatever tower your phone is now on? suposebly pulling the battery will do it to.. Also get Anycut and make a short cut to phone info an toggle radio on off?

same problem occasionally

i'VE had the same issue, occasionally, I'm fairly certain its the sim card, not the phone. you can take the battery out, pull out the sim card, clean it up (don't use watter or anything that'll scratch it of course) and put it back in, make sure its securely in there, and boot up the phone, however, I've also noticed that sometimes in the middle of the night (like around 2AM to 330AM PST) sometimes cell coverage gives out for t-mobile where I'm at (friends confirmed), if you only just recently recieved 3g in yoru area, they are doing maintenance to get it up and running perfectly, so don't fret too much
EDIT:
Another thing I did was made sure to mess with the APN settings. dont' edit them, just try and change your APN from T-mobile to ATT, wait for it to say "not supported by sim" and then switch back over to T-mobile, that worked for me twice now

I'm having this same problem, only I can't surf the web or use the market. :\ Any help would be GREATLY appreciated.

Sorry to reply so late but the probem is now solved, this is what I did, I took out my sim card out the phone put it in an old phone to see if my sim had any issues but I forgot to take out the sim and put it back in my g1 went sleep.
Next morning put the sim in my g1 and all is fine got connection and all functions working, then waited a few hours no problems at all.
So I rerooted installed the danger spl and custom rom and the probem has just vanished, haven't got the slightest clue why that happened or what caused it.
The sim is new just under a month old lost my old 1 uk t-mobile charged me just under a £10 for a new 1 even if your on contract thiefs

its probably
A) the SIM got dislodged or
b) your G1 contacts were dirty.
All the above could cause the phone to not read the information on the SIM
Blowing the dust out/wiping the goldcontacts where the sim goes, and tightly inserting the sim might help, grandmegabosses

Nexus isn't finding network :mad: Help is needed

My Nexus was on 5.0.41, all working sweet, then it stopped "finding" the network. No update, flashing or anything was done prior to the problem.
I tried a SIM from another provider, but still - the "No Service" is written on screen, and when I try to search for networks, it says "Error searching for networks".
I then tried the following ideas (nothing helped):
- Reflashed the Radio image.
- downgraded the Radio image.
- Upgraded it again.
- Flashed the Stock ROM (unrooted and rooted).
- Flashed CM5053.
All was done with wipes as needed.
Any suggestions will be more than welcomed!
Can the device just get bricked like that? with no reason?
It sometimes identifies the SIM's provider (Orange for example) but always with No Service.

It sounds like your SIM card slot isn't holding the card in tight enough to make full contact... try putting a business card, cut down to size, between the SIM and the phone's frame (note, not the contacts side, but the back side) to force the SIM down onto the reader tighter.
If that does nothing, not sure what to tell you?

it didn't help

I'm Italian and I have the same your problem .. I only work in 2G GSM'...ve tried to see if you do so?
I opened another tread here Forum

You need a new SIM.
I just had this problem on Friday. The SIM some how falls of the network and your provider network will not allow it to reconnect.
I can't remember, but if I am right Orange is owned/owns by T-Mobile. Hence they have the same network.
The puzzling part about this is why it happens. This is the second SIM I have gone through with my N1, I also had one go with my G1, my sister bought that G1 and the SIM went out again. My mom bought her G1 same day as me and hers has died once. My friend has a MT3G and his has died two times now. I find this extremely annoying.
I tried every suggestion on the internet for repairing or troubleshooting a SIM. It is a waste of time. Well, everything short of dropping it in isoproply alcohol to clean the contact.

I tried a 2G and a 3G SIM on mine, and had the same result, so my problem is different.
My device just doesn't register with the network, no matter what provider or SIM generation I choose.
Can I ask for a RMA if I unlocked the bootloader?

I do not know you definitely do not pass it under warranty

Ryan then you say you clean the contacts of the nexus or the sim with isopropyl

Mine is now doing that as well and so far everything that I tried isn't fixing it. I get it to connect briefly with edge and then nothing. I am going to try a new sim tonight after work and see if that helps, otherwise unsure of what to do after that...anybody got any answers or suggestions?

I've been suffering from this... have an RMA coming but I got mine to work. Make sure you also have CDMA preferred on there or whatever the default is. If it says unknown you have to reboot the radio somehow. I pulled my battery, waited 5-10 seconds. Then i went and checked airplane mode on and off. Then i checked the service menu again. I can't remember if i had to pull the battery another time but it came back from "unknown" to cdma preferred. You can also try turning the radio on and off via the service menu. Finally select your radio bands for your region by pressing the menu button under phone information again in the service menu and select radio bands. I'm not sure if automatic is a good or bad idea but it couldn't hurt testing it if you still have some issues even after selecting your region specific bands. After this you should be able to maybe search and register or you may need to turn the radio on and off again via airplane or the service menu. I played around with it alot to get it running again.
Also I'm tmobile usa using the one for t-mobile bands. I'm not sure if CDMA preferred is a world wide setting or if its gsm or something else.. but the bands are specific to your region definitely.

Have you paid your bill?

That's weird, my mobile data also stopped working around the time the OP posted
I am not joking either, I haven't been able to get it working again - I just figured the custom rom I put on recently had screwed up and I'm currently in the middle of getting all the files ready to put eXistenZ ROM on instead - happened to see this while looking for a 253 ftf for the kernel.
Probably a coincidence but still weird.

Try reflashing stock kernel

I think you need to request the configuration settings in your network provider.

UPDATE: Just found out there's a major outage of 3 UK's mobile internet! No wonder my mate couldn't connect...
Hmmm. Strange. There's a bloke here at work who's having the exact same problems with his XZ.
He's on 3 (UK). Swears blind it was connecting and working yesterday - this morning, nothing. His phone signal is fine, just not mobile internet.
Checked his APN settings, his mobile Data is "ON", the phone knows it's connected to 3, it says he's picking up HSPDA, but nothing will connect. It won;t even connect to re-install his internet settings through the "Xperia" menu in settings.
He says it did update to the .253 firmware on Sunday night.
What networks you guys in the UK having probs with?
(I'm only bothered cos I;ve got the exact same phone coming today on the same network )

Droid Turbo on T-Mobile. Need Help!

So I've had my droid turbo for a month now and I've been using it on T-Mobile and it has worked fine, no issues whatsoever, until yesterday when the service just stopped working. I have no signal at all. I took it to T-Mobile and they couldn't fix it and then Verizon who also couldn't fix it. I tried At&t and Verizon sim cards and they work, but for some reason T-Mobile sims don't work anymore, I woke up and it just had no signal. Also, whenever i put in my sim, i get the message "Restricted access changed voice service is blocked" Please help!!

I've been on T-Mobile with my Turbo for a little over a month now. Delete any APNs if you have any, reboot and test.
If no profit..
Turn wifi, Bluetooth, nfc, anything that connect to any kind of network off and run it dead, then charge it to full and boot back up then turn what you need back on, should have signal again.
If not..
Try another sim from T-Mobile, yours may be damaged if you frequently take the tray out over and over..
The Last possible solution would be to reset the phone entirely, so make backus f what you need beforehand. Then set it up from last backup saved to google if you have one and pop the sim in, let it sit 2-5 mins, reboot, then give it ~2 mins and you should have signal recovered.
If not, then may be an update gone awry or if you have it rooted and such, maybe something you used broke it.
Last problem would be a bad antenna, so try all the above before trying to replace the antenna.
Hope the best of luck for you :
Only Problems I've had on my Turbo was it turning wifi off randomly here and there, making me do a reboot every few days.
Dropped signal once, but that during initial use, so not much to blame on it there

I've been using a Turbo on tMob since 2 wks after release. That said I've run into the same thing a couple times over the past yr. Out of nowhere it just acts up & stops working. As suggested above I'd say about the smae things. So to no repeat it all my first suggestion is try getting a new Sim card from tMob. First time it happened to me it was my sim, other 2 times it was not, sim was good. Only option to fix it on my end was a factory reset of the device. On the resets tho I made sure to use tMob sim, but i also did not start the process until the msg pops up on the turbo saying its " Not a Verizon sim card" i'd clear that and then start the process of resetting it. So far so good as of late, been at least 3-4 months since the last time i was having troubles.

Sony XZ3 not connecting to network - help

I have a Sony XZ3 which was bought second hand 18 months ago. It's worked fine until about 1 month ago when it didn't get good signal or data anymore.
I am in the UK and use a giffgaff sim which runs on the o2 network. I found after some investigation that the phone for some reason was now connected to The Virgin network and I can't get it off.
Giffgaff have not been able to help, they said the phone is now locked to Virgin, Virgin said the phone is not locked but they did confirm that when it was bought new it was from them. Checking the handset it actually does say unlocked.
Have done a sim swap - the sim works fine, it's the phone that's the problem. It does the same with a different giffgaff sim in it.
Have reset network but it doesn't work and just defaults back to Virgin again. Have done factory reset 3 times but again just defaults back to Virgin every time. It says all other networks unavailable.
Can someone help please with what to do next?
Is there some kind of hard reset which will wipe everything including whatever is causing it to be switching to Virgin all the time? Or some way to override it?
It still shows no signal most of the time even though it says it's on Virgin
Thank you.

Hi everyone. I have the same problem. Since some weeks ago my phone doesn't recognize any network, not wifi or mobile and the it reset alone. I was told that it might be a software problem. I have already done factory reset and software repair from xperia companion but the problem persists.
I don't know if any of you knows if this is a hardware problem. But also I was trying to install a custom rom for android 11 to see if the problem is solved, but I can't unlock the bootloader either. I followed Sony official instructions to do this but for some reason Windows 10 doesn't recognize the phone after I turn it off and the press and hold the volume up button while connecting the phone to the PC with the usb cable. The drivers are installed but in the device manager it appears with a code 10 saying that the device might not be able to be recognize.
I have already checked if I can unlock the bootloader and it says yes.
Thank you very much.
