My MDA lost its signal and it can't seem to reacquire it. Is there anything I need to do? I had this problem before and it sometimes comeback after a soft reset but I have been doing that for the last 15 minutes and it is still out of service. Any suggestion would be appreciated.
Do other phones on the same service work? One day i thought my phone was broken too. I kept losing signal. then i went to work and it worked fine. Turned out there was a problem with the tower by my house.
No it is not the tower. I experienced this problem a few times already. It would lose signal and then it would take it a long time for it to reacquire/register with Tmobile.
Sometimes it takes a 1 minute and sometimes it seems to never (i waited for 15 minutes and then I do a soft reset) come back.
I'm not sure if this has happened to TMo customers, but I know Cingular customers have experienced fried SIM cards. I've personally experienced this and had to get a new one from a Cingular store. Thankfully it was free. I experienced the same symptoms. My phone would never acquire signal, even after a hard reset. If you can, try your SIM in another phone, or better yet, try a different SIM in your MDA. Good luck.
Several times recently (I'm not sure whether it started after I installed the OTA update or if it happened once before then) I have noticed that my phone says "No service" and doesn't pick up T-Mobile again until I power cycle.
It's not that unusual for me to see 0 bars of signal strength in my house; there are dropouts at various places, and I saw the same thing with AT&T on previous phones, so it's not a T-Mobile or Nexus One issue. The problem is that, once every few days, I will pull out my phone and see 0 bars and "No service" instead of "T-Mobile," and nothing short of a power cycle reestablishes the connection. I've tried going into and out of Airplane mode, with no effect, and I also tried using Settings -> Wireless & networks -> Mobile networks -> Network operators, and it never found any.
Maybe related is that when I try to power cycle after this occurs I have trouble doing so -- a few seconds into the shutdown sequence the circling arrow stops moving, I get some sort of notification "ping" and the trackball lights up, and the phone just sits there for a long time. Eventually it reboots -- whether because whatever it's waiting for times out and it continues the shutdown sequence or whether it's responding to my frustrated poking at various buttons while it's sitting there apparently doing nothing, I don't know.
If it's a hardware issue, it's very intermittent; I always have service after the reboot, and as I said, this only happens once every few days. I'm inclined to think it's a software or configuration problem (I'm using the stock 2.1-update1 firmware). Any thoughts or suggestions? TIA.
It happened again this evening when I had some more time to play around with it, so I have a bit more information about this problem.
When I tried Settings -> Wireless & networks -> Mobile networks -> Network operators, the circular arrow spun for a minute or two and eventually a little pop-up appeared saying, "Error searching for networks" or something like that.
It occurred to me that the SIM card might be bad or have a bad connection, so I installed an app (using wifi -- which, BTW, I had on throughout this whole process) that allows you to copy your contacts onto the SIM card and ran it. That seems not to be the problem, though, since that app could access the SIM card just fine, while I still had no service.
I toggled Airplane mode on and off, but there was still no change. I then again searched for network operators; the circular arrow appeared and stopped, then a couple of seconds later the phone spontaneously rebooted and I have service again.
Anybody have any guesses as to what these symptoms might indicate?
Every so often i got service but I cna't send text messges unless I power cycle. If I try to airplane mode cycle it won't let me get out of the mode.
wow, a bit refreshing knowing that I'm not the only one with this issue.
I'm on T-mobile and within the last week I've had 2 occassions where I looked at my phone and noticed no service, a power cycle caused it to freeze on "powering off" screen and I would have to pull the battery. After it booted it I had full bars again.
Within the last 2 weeks I have had issues where I would not be able to send a text messages until i power cycled.
The last time I had no service was 4 hours ago. I had to pull the battery to power cycle and get service again.
Thanks for the reply. I, also, pulled the battery the first time it hung in the shutdown sequence, but as I said in my first message, since then I have managed to complete the power-down after the hang, either because whatever it was waiting for eventually timed out or because something I did (e.g., holding down the power button for several seconds) overrode the wait. Next time it happens I'll try just waiting to see if it will complete the shutdown on its own.
Just out of curiosity, did you have wifi enabled at the time this happened? Bluetooth? I'm not sure whether it's relevant, but I leave both on all the time.
As for the text message problem, I don't send a lot of texts, so I probably wouldn't have noticed if I were having that problem and can't comment on any correlation.
Oh, and a couple more questions: do you have NetCounter installed? And are you in a location where you sometimes or frequently get 0 bars of signal strength?

I have had similar issues with other phones...
For me it turned out to be an issue with my sim card.

I usually have both bluetooth and Wifi enabled all the time...
Dont have netcounter installed.
Dunno about the SIM card issue, unless its a combo of the N1 and my SIM card, because I swap to using my BB 8900 once in a while and I never have text message or no service issues.
Im experiencing the same problem, I have dropped calls in some spots around town (when changing towers it seems), I drop service when inside my home and cant send texts (until a power cycle), horrible 3G speeds of less than 1MB/S all around town (driving and standing directly under the Tmobile Tower that across the street from the tmobile store).
NONE of this happened with my G1....my 3G speeds always sucked though but were usually around 1.5-2.1MB/S.
Im located in Fredericksburg,VA.
(MY PHONE IS NOT ROOTED AND IS RUNNING THE OTA UPDATE1)
Im pretty sure it was the radio update, cause after i get out of a place where i get no signal at all, and i get to a open place I have to reboot the phone to get signal again
I've been busy for the last six weeks or so and haven't been following N1 news around the net. Has anyone heard of any progress on this issue? It seemed to go away on my phone for a couple of weeks, but it's back with a vengeance: it's happened to me about once a day for the last few days, which is more frequently than any time since I've had the phone, so I'd really like to get this fixed somehow.
Can you take a youtube video of it? the more the better to get Google to fix it.
Also these issues seem to be related over here too http://www.google.com/support/forum/p/android/thread?fid=1cc152dbb797df2f000483d7c88e343e&hl=en

Thanks for the link. It seems to me that several different problems are collected together there; mine is specifically the one where I go to zero bars (which happens fairly often; I have several dead spots in my house) and it never comes back.
A video of this would be pretty boring to watch; there's really nothing to see. The signal strength shows zero bars with an "x" and the home screen shows "no service." Trying to power off, or going into and out of airplane mode, shows the spinning arrow for a few seconds, then it stops; a few seconds later the screen goes blank; then a half-minute after that the multicolored "X" appears and the phone reboots itself.
No SMS Gateway
I think this is a separate issue for the phone not switching back to a connected state with the service provider. In the case of SMS, I have also noticed that you may have signal but you have no SMS gateway. No idea where it goes or why it does that.
For whatever reason you loose the SMS gateway phone number settings and become unable to send text messages without a reboot. This is evident by visiting:
Phone
dial *#*#4636#*#* (if you happen to mis-dial this start over after clearing the display or it won't work)
Phone information
Under SMSC: press Refresh.
If no number displays (in my case +12063130004) then you have no route for the SMS messages to take. Entering that number and pressing update will fix it but just restart so it can pick it back up from the SIM/Carrier configutation.

I have this issue sometime in a supermarket here, if I'm in it shopping for a while I loose all signal and have to reboot, also happened with my MyTouch jut didn't have to reboot the phone, but if I'm in there for a quick purchase, it works OK
@wmm, I'm seeing exactly the same issue (zero bars + reboots) and found another guy on the cyanogenmod forum with that problem. Maybe you can add your last_kmsg to this thread, even though you're on stock. http://forum.cyanogenmod.com/index.php?/topic/1599-loss-of-signal-no-reacquisition-issue/

Yep, that certainly sounds identical to my experience. Next time I have the problem I'll force a crash by toggling airplane mode instead of trying to power off (it seemed from the thread that last_kmsg would not be saved if there is a normal reboot, and indeed I have no last_kmsg from the reboot that resulted from trying to power cycle after the last time I had the problem).
Thanks for the cross-reference.

That would be nice, but I haven't seen any activity on the issue on the Android developers' board. Speaking as a programmer, these intermittent, once-every-few-days kinds of problems are a real pain to debug, so I can't blame people for not wanting to tackle the issue...
I had this issue but fixed it by installing the Radio Rom and OS again from the last update. Has not done it again. Now its a power button issue lol.
Problems with my girlfriends eris. Not used to the world of sim cards, att, etc (verizon myself). Apparently today it started.going back and forth between no service, but it would sporadically get one bar of service in places that usually have full service. Under phone identity, "voice msisdn line 1" reads unknown. Could this be the culprit? I've tried pulling the sim card, rebooting, and that's no help. dialing a *228 or equivalent is probably out as the phone doesn't usually hold a signal long enough for a call. Any ideas?
Mmmmm...Froyo!
Wait... the Eris or the Aria?
Have you pulled the battery? also how often does she reboot the phone. I have a similar issue which Tech support finally told me there is a single 3G tower with week signal so when the phone tries to connect to it and can't it kicks it to emergency services only mode and loses the towers. I have to reboot my phone a couple times a day. If service does not improve soon I will be switching carriers.
This also happens to my daughter and wife's phones which are pantech basic handsets and not smart phones.
Oops, aria lol, I always goof up the name for some reason. This is a new problem, we are in downtown hartford and signal has never been a problme before. She claimed she pulled the battery a couple times along with the sim card, and I did two or three times when I got out of work. We let it sit for a bit, and she started saying that she just wants to go back to a flip phone after I posted this up and things magically seemed to have fixed themselves...
Ah, yeah I've had the same issue recently. No matter what ROM I use, there are times when I would be randomly disconnected from the AT&T network.
Hello,
I have the Sony Z2 on Tmobile USA, completely stock (no ROMs, or modifications).
Approximately twice a day, my Z2 randomly stops receiving calls, making calls, and accessing the mobile internet. It still shows plenty of "bars" on the reception meter, thus I have no idea that I'm not receiving calls.
When it happens, this can only be resolved with a restart, or turning on Airplane Mode, then turning it off again. The problem will usually come back within 6 hours, requiring another restart cycle.
If I have WiFi enabled when this is occurring, then I can still access the internet via WiFi, but I will not get calls and text messages. I get no indication anything is wrong, until I try to place a call and it fails.
When this happens, the "Signal Strength" meter (under "About Phone", "Status") does not change, it would read something like -95 dBm no matter where I would take the phone (even in areas of poor coverage). It appears the phone simply looses synchronization with the mobile network, but doesn't notify the user. Other phones on the same mobile carrier continue to work perfectly at the same place, so it's not a mobile carrier issue.
I've had this phone for 8 months, and this is a new phenomenon.
This is Z2 model D6503 and I am on the latest firmware (Android 4.4.4, build 23.0.1.A.0.167). Sony support said "reset the entire phone", of course.
Please share any thoughts you may have about what could be wrong.
Any input is very much appreciated. Thank you!

Most probably random software issue. If you installed any apps recently one of them could be the culprit. Uninstall them or trying booting into safe mode and see if the problem persists with continued usage.
As a last resort you can factory reset the device using the PC companion. But since the lollipop update is round the corner wait for it and see if the update fixes the bug.
If a factory rest or firmware flash doesn't solve the problem its a hardware fault, return it and ask for replacement.
I know I randomly get data drops, but I always cycle mobile data off and on to fix it. Next time it happens, I'll try to make a call to see if this is the same bug that I've having.
Quick update:
Right before the problem started, I installed the current-as-of February 2015 version of Audible on my phone.
After I uninstalled Audible, the issue appears to have disappeared (haven't seen it re-occur yet). Bizarre, but that's the situation,
