Nexus one not reconnecting to mobile network

[laughter95]

My N1 will not reconnect to a mobile network if it has been sitting for a few hours in a no-coverage area, such as a building. I cannot get it to reconnect, even after refreshing the network search. This action only leaves me with no result or a message saying that there was an error in searching or connecting to mobile networks. The only solution is to restart the phone. Every time I try to turn the phone off after this error has occurred, the shutdown sequence hangs until either I become frustrated and do a battery pull, or it automatically restarts and do a battery pull, or it automatically restarts itself. Furthermore, the phone used to give me an error notification saying that the phone does not have carrier service. Now, it does not. Furthermore, the phone used to give me an error notification saying that the phone does not.

I tried uninstalling all my programs and nothing has worked for me. I've also tried toggling the airplane mode to no avail.

I'm considering putting on the cyanogen ROM to see if it would fix this error, but I am hesitant to void my warranty. It's a pretty serious problem as I'm very frequently in a building where I don't get service. It's quite frustrating to have to wait to reconnect to a mobile network once I leave the building and hope that the error didn't occur or have to do a battery pull every time I realize that the phone simply won't reconnect.

Can anyone suggest any solutions?

Mod it. What have you got to lose? Your overall performance will increase. The radio signal may even improve. Your call.

thanks for the tip. i've been thinking about it. it's the warranty i don't want to lose. eh i'll keep thinking about it.

this phone sucks. it's glitchy, can be sluggish. iphone got dumbed down but at least its functions work.

Hey!
You dont want to lose your warranty, then use it!
Your phone seems to be faulty...

 

[vr24]

My phone is experiencing the same problem as of yesterday. Won't connect. Wonder if it's a T-Mobile issue.

Its only glitchy coz you have stock rom
Cyanogen is really stable and adds alot of features / functionality.
Fair enough you dont want to lose warranty but i remember in the general thread that lots of hardware failures and others can still fix your n1 under warranty even though they unlocked the bootloader.

 

[Dorick]

I too have this problem, hopefully the 2.2 update will fix the problems.

 

[faraz1992]

Can you guys confirm if its android or your service provider thats causing this...

I have the same problem and it's starting to bother me a lot because my car is parked in a garage with no coverage. My in-car BT then becomes useless as my phone won't reconnect to the network once I exit the garage

I just called Google support 10 mins ago about this and they went through normal protocol to reset to factory settings. They then called Tmo and let them know what the issue was while I was still on the phone. Tmo unregistered my phone from the network while my battery was taken out of my phone and then reregistered my phone to the network. Tmo asked me to monitor this for a few days and call them directly (not Google) if the issue persists. They will then elevate this to a higher level because they feel this would be a network problem, and not a hardware issue.

Hope this helps! Please post what you have tried to solve the problem!

^ it worked! my phone reconnects to the cellular network after what Google/Tmo did for me on the phone!

I haven't tried calling tmobile, but it is NOT something that will be fixed by hopping on cyanogen's rom. I've been rooted on cyanogen's rom for quite some time and this problem still exists on my n1 which is SUPER annoying. I will try calling tmobile to see if they can fix it on their side, but rooting is not the fix here.

I had the same issue. I used anycut and phone info shortcut and changed the wireless default setting to us and it totally fixed the problem. Have not had that issue again.

I resolved this by going to the T-Mobile store where they replaced my SIM card. They made a copy to a new SIM card, installed it and everything works fine.

For the record symptoms included:

* "Error while searching for network" message
* Found networks but said "your SIM card is not authorized for this network" when connecting
* Network listed as "No service" or "Emergency calls only | T-Mobile"

I get this too with an at&t phone.
Have asked for a replacement device from HTC (since the reception is crappy to begin with).
I also have audio quality problems when reception is only 1-2 bars.

Will see if the new phone is better.

 

[wmm]

I had this problem regularly. It hasn't happened once since I upgraded to Froyo, so I think it has been fixed in that release.

 

[deenn]

sometimes have this too, i fix it by going to the settings > wireless > mobile networks > APN. at first i deleted and retyped my password in the selected APN, now i just click my network in the APN settings, don't change anything and leave. It immediately reconnects after that.
edit: and i have stock froyo & live in belgium.

 

[nexusdue]

I got a new, replacement phone from HTC today.
This new phone has a BIG PROBLEM with this issue.
Even if I am only without reception for a couple of seconds (go through the garage, etc.) it will not connect to any network until I reboot.
My old phone would only experience this problem maybe 25-35% of the time.
Very, very annoying!!!

I had similar issues and called tmobile support. I was first linked to Google support. They went through the similar process as described by in the first page. (#*#*4636*#*# select USA band etc). While I was on hold, they called t mobile tech support and had them reset network connection and tried to get me onto a different tower etc.

Tmobile support stated that my sim card (had for about 2 years) was the cause of the issue as they can't handle smartphones as well as their new sim cards. They also said the new sim should improve reception and connection stability (Don't see how a new sim could do this but what do I know?). Moreover, they noted my account and told me to go into the nearest store for a new sim card. Went into the nearest tmobile store told them the issue, they pulled up my account and gave me a new sim. Took less then 5 minutes and I have not had the issue with staying connected to the tmobile network.

I will update this after a few days to see if I still have the issue.

I have the same problems that i cannot connect to network here in germany. first i think it was my sim card, but befor i had another provider (E-Plus) where i had the same problems with reconnecting to network. and one day my eplus sim card is broken so i had to buy a new one by t-mobile. i have tried a lot of roms from here (cyanogen/ 5.0.7 /5.0.8T5 Kangorama rodriquezstyle and leofroyo) everyone seems to have the same problems with reconnecting to network. i hope im not alone with my problems and someone can help.

 

[Ssantos6981]

hmm...

Count me as another. I just upgraded to froyo and it went beserk. Had no service for a while. It would only come on after constantly tapping "select network automatically" until it kicked me out of the menu. It started getting better but kept kicking me out of 3g. I set it to stay always on 3g and it seems to be better... still I'm going to call tmobile and see if I can get a new sim as well.

Thanks for the info guys!
