Nexus one not reconnecting to mobile network

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...

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.

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

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.

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.

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.

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.

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!

'Radio' Problem

Hi
Can anyone shed some light. My SGN suddenly lost the ability to make phone calls ('Mobile Network Not Available' message), cannot connect to wireless network and cannot connect to mobile data. I rooted it about a week ago and it has been fine up until now.
I tried unrooting, re-rooting, re-flashing current firmware (LA6) and reflashing just the radio (LA4). All processes were successful but didn't fix the issue. I tried a different SIM, but no dice!
Is there anything else I should try? Does it look like I have a hardware problem?
Thanks.

Further info - switching to GSM Only has restored mobile internet and wireless network connection (?????? WTF???) BUT cannot make a phone call.
Help please.

Sort of the same problem over here, only Emergency CALLS. Sim slot looks defective. Tried everything. Thickened the SIM, Flashed stock and rooted roms with Odin and Mobile Odin. Several factory resets and wipes. Sim is ok, using it in another phone now. Other sim also doesn't work.

I sort off solved my own problem while leaving myself with a worse one!
Pushing my panic to one side, I discovered that I had wireless and bluetooth but no phone, text or mobile internet.
I checked online to discover it had been blocked!
Phone was a private sale so back to first owner to get network details and see if he has done anything silly - like report it lost or stolen!
Arghhhhhh!

Probably wanted to use his insurance and claimed it stolen. You're screwed I'd think

HTC one with Three uk - Data connection issue

Hi Guys,
Been searching the forum about this but cant find anything so i have registered myself to open this thread.
So, i have recently bought the HTC one from Three (Moved from o2) on the unlimited one plan. The only problem is that I cant get the internet to work, the phone says i have 4 full bars of signal with 'H' connection but the pages will not load at all. When it does work, it will work for 10 mins and then would just stop working again till it decides to stop being moody again.
I have tried switching off the phone, re inserting the sim card but the problem was still there. Therefore, I have called up Three customer services and they said that ' THIS IS A KNOWN ISSUE AND THERE IS NOT A FIX' he also agreed that I can cancel my contract (employees in the store have different opinions all together). I now have a phone which cant get online (95% of the time) and a data plan that i cannot use!
So can someone who has this phone with three network UK please tell me whether you are facing this problem? If no one is facing this problem then i am happy to put it down to the handset and get it replaced if not i will leave altogether.
Please note, web browsing on wifi is fine and when i have this issue wifi is switched off.
Thanks,
Mareen

It's do to Three being too heavy congested... I get this sometimes on my LG fone. I have 2 different APN's that I use for Three & they both do this. Try, going into Airplane mode & then back on to reset the data connection. Sadly, this will happen due to more people using Three & they can't support the amount of bandwidth.
This is what happens with Unlimited data plans. The more people use unlimited data, the more likely you will have problems connecting at peak times... thus, meaning whats the point in Unlimited?!.
IMHO, network providers should be making sure they have reliable data connections rather than aiming for 100+mps data speeds!.

Thanks for your reply but this is not just peak time issue. I face this problem all the time and the customer services person also said it's a known issue and possibly there won't be any fix. He also stated the phone gets stuck in this mode due to all the apps installed by three but if that is the case then surely more people would have flagged this up.
I just don't know what to do. This one plan is so good and everyone at work are mostly on it but how can they connect and I cant from the same location same time if it is what you are insisting about congested network?

Wow a lot of hate for 3. I am using the one on the 3 network and do not have any problems whatsoever. I get consistent good speeds between 3 - 10 mbit/s without any of the issues described.
I am in London which is very congested. I am using an unlocked htc one and not a phone provided by 3 so it is possible that it is something to do with 3s Rom. But i think it is much more likely just a bad device and you should get it replaced.
It is definitely not a "known issue" with the phone or we would have heard a lot more about it on these forums.

Exactly! Hence this thread. Im also based in london and this issue happened in any locations i been too! Im torn between staying with them or getting it replaced.
If getting it replaced i will lose the 7 day cancellation period.

& tbf, mine doesn't just happen on peak times either. When I worked for O2 in Pay Monthly, I used to advise customers thats why they have a fair usage in place to prevent data connection issues. Unlimited Data on O2 used to be around 2GB/3GB & anyone who used to go over a lot used to get a text to let them know of cut off there data connection for that month. I left O2 a year ago after working for them for 2 years in Customer Services in Pay Monthly, so know a fair bit about signal & data & why there's generally a fair usage in place.
Three are VERY good at marketing themselves as All You Can Eat but as more people jump onto Three's network, the more you will have data issues. What Three have said is complete crap as my fone is sim free with no bloatware & its all due to there network & NOTHING to do with what fone you have.
I am on Three's Pay As You Go £15 300, 3000 Texts & All You Can Eat Data which Includes Tethering. Soon, Three will have to either cut back All You Can Eat or build more on there infestrure...

i would suggest its a problem with the '3' device. I am on a sim only plan with '3' and using a sim free device i purchased from phones4u, the phone works fine with only the occasional slow connection which i personally put down to congestion. I am in Wiltshire and generally get around 3 to 15mb download depending on time of day and amount of traffic on the network.

Never had a problem with my one on 3! Although in Milton Keynes today it went to Roaming!!!!!!!! Still worked (roaming was turned off) off to London next week so will see what happens with mine. Still mega impressed with the phone...

No issue with my 3 device in Essex and London, although do have issue 40 floors up but I expect that!

I'm on a SIM free device with Three. Never had a data problem yet and have excellent speeds.

Have you tried
1. Check the APN settings (try to delete and add again manually)
2. Set mobile network to 3G only (as opposed to the 2G/3G/LTE option)

Here I get barely 200Kbit/sec down and a megabit up, HSPA+ 21.6Mbit
In the next town I get 15+Mbit down and over 2 megabit up, again HSPA+ 21.6Mbit
Massive difference, and consistent with both places too. Three acknowledge the congestion issues and claim engineers are looking into it, but its been months.
Same speed on T-Mobile here so it's probably a MBNL site...no idea who to complain to tbh!

I get 10-20 mb dl speeds on Birmingham, never had any issues, don't really get the three hate. Been with them for 5 years.

Oh wow!
I'm getting the exact same problem but couldnt find anyone mentioning it so thought I must be doing something wrong!
I'm on EE (Orange) and I get cut outs quite regularly even though it shows full signal. Usually turning it on and off again or switching to airplane mode resolves it but it really is starting to pi$$ me off! :crying:

with ee its a totally different problem, there is a thread on it somewhere, its basically when you switch between 3g and 4g its cuts off,
have a look for the thread

I'm on Orange (although the phone usually shows EE) and I'm seeing this too.
If I leave my house, quite often as soon as the WiFi disconnects, I don't get a data connection. Again, I have the little "H" or "3G" displayed but I need to hit airplane mode on/off to wake it up.
Starting to wonder if it's a handset issue... I'll see if I can run some logcat next time I'm moving around. Doesn't do it all the time, if I leave work, then the wifi > H transition seems fine.

Thanks for the info guys. I used to be with three when they actually entered UK and their service was really good back then in my area. So i think this problem lies with the handset i think. Im going to pop into store and see what they say. Im just worried that if i do get a replacement it will have gap and power button problem reported by other users.

no issues at all, oldham

OK, decided to stay with three but they have promised me to replace the handset. So nice of them. I can only do this Monday as I dont have all of the paperwork with me.
I will keep you guys updated with how my new phone gets on.

tmobile experiences?

Since apparently people can get this phone working on tmobile.. I was just wondering what your experiences were.. does it work easily/effortlessly? (I would likely use reseller lycamobile) and sometimes use Verizon reseller page plus

I am not sure what you mean by "easily/efortlessly". It takes a bit of work and patience to root and modify the phone. Once modified, the phone is usually back at the new phone state, so you have to reinstall all of your apps and some of the setting. If you install the wrong settings, it messes up the phone, so it is best to only use Titanium Backup to reinstall the downloaded apps and the update and restart the preinstalled software. I was not able to use Titanium to reinstall my text messages, but it did restore my WiFi passwords.
Once the sim card is installed and running, I get an occasional "toast" message about a UI error, but none of my apps seem to be shutting down when that happens so I just ignore it (I think I may have missed a step that fixes that). Some apps are no longer available because they were tied to Verizon Service (Smart Actions had trouble so I left it off).
I seldom get more than 2 bars of HSPA signal. However, that gets me about 7 MB/s download when I am stationary (about a good as my home network on a cable modem and about 1/2 the speed of Verzon LTE) but the power consumption is much lower. I can expect my extended battery to only use 30% by the end of work vs. 40-45% with LTE active (both on WiFi). Off of WiFi I get just over 50% longer life than I did on LTE.
I have no issues hearing or being heard on a call. I get signal almost everywhere I did with Verizon in the Metro Indianapolis area, but I seldom have a good Data signal on I-65 between Indianapolis and Gary (voice works).
I hope that covers the questions you had in mind!

I take it after you do all this.. you can't just flip the phone back onto verizion.. after running say "tmobile" (you have to re-rom the phone or something right?)
I also assume you can switch to AT&T though without much trouble?
Does the phone have a external antenna port.. I would assume "no" ?

It is not so much "re-rom" as you have to wipe the data cache clean, which means all or your apps and messages are erased.
I have not tried switching between t-mobile and AT&T (I don't have an active AT&T SIM card) but I don't think that will be a problem. The boot looping is caused when you change the settings in the build.prop file and you would not need to do that when switching between GSM carriers.
I can't remember if the Bionic has an external antenna port (my wife has one, and my daughter the other - I am on an old iPhone 3GS until I replace somebody's handset).

There is an antenna connector or the phone. Pull the back off and it is visible between the battery and the lower microphone.

Network outage issues on Note8

Hi
I have been having issues with my Note8. It loses the cellular network periodically, and doesnt acquire it back. A reboot is required to get the network back but then doesnt last long. I have tried most everything. Listed in order
1. Reseating the Sim / Removing the SD card to check if that was an issue
2. Switching network from 4G to 3G to see if that was the issue
3. Factory reset a few times, including once while not installing apps and letting the phone run with less apps
4. Changing SIMs
5. Changing SIM tray with an S8
6. Using another network sim card
7. Running the phone in Safe mode.
I have exhausted everything that I can have done. Any other thoughts or suggestions?
Phone is within warranty so I can get it fixed, but the issue is that I live in a different country now and they will charge to just take a look at the phone.
Side effect is that while hunting for the network, the phone gets hot and runs down the battery.
I am hoping that there might be a software issue, as the phone does connect to the network for a while before losing connection.
Any help would be much appreciated.
Thanks a lot.

It looks like you have done all of the obvious stuff - it's starting to sound like a hardware fault to me.

Thanks! My worst fear unfortunately.
Was hoping someone might have a software solution or something else which I could try but...

i had same problem with 2 x galaxy s8
after they test for a month and big fighting with those F customer care
they replaced 1 with sealed box and the other one they changed the motherboard which doesn't help , still same problem
i sold both
