Network not registering - Nexus One Q&A, Help & Troubleshooting

Every once in a while I would notice, when I unlocked my phone, it would say "Emergency Calls Only" as if I didn't have a SIM card in.
Everything would still work after that such as text messages and calls, so I just figured it was a weird issue with Cyanogen 6 RC1.
Starting today, I was getting that message every single time, and also a notification that I couldn't register on T-Mobile's network.
I got on T-Mobile's live chat help, and they said there's nothing wrong with the service in my area. The person also had me tell him the SIM card number to ensure they had the right one in their system, which they did.
After this, I figured it might still be because I'm running CM RC1 so I upgraded to RC3 and I"m still having the same issue.
T-Mobile's "my account" program is no longer set up, so I don't get the notification, but I still get the emergency calls message on the lock screen.
Also, I AM connected to the T-Mobile network, but it just won't recognize my phone.
I was wondering if anyone else had any insight...

Which radio are you using? Has it done this since upgrading from stock rom?

Yes I just had this similar issue yesterday and I'm on at&t. Also, everything on my N1 is stock.

I had the froyo radio but then I flashed the new Korean radio and it didn't help.
I did, however, pull out the old trusty G1 to have a working phone again. But when I started it up, it reported not having a sim card. Im going to go to tombile tomorrow to get them to test it. I'll report back in case someone else has the same issue.

You might try cleaning the SIM card contacts, they might be the culprit.

I went to T-Mobile and he confirmed it was the sim card. Actually he said it was fairly common for them to go bad. No charge and I'm working 100% now. Thanks!

I have not in my life seen a dead SIM card, it was a month ago that somebody was asking around the forums what and why. I was shocked
And T-Mobile says it's common.. lol wut?

Maybe the Nexus One eats them lol

[Q] "Refreshing Sim Data" annoying pop ups

I've got an unlocked Singapore i9000 with the European JG1 firmware installed and using it on AT&T in the US.
The phone frequently pops up an annoying message about "refreshing sim data". It pops up, then fades away on its own.
Other than the obvious, what does "refreshing sim data" mean, and why does it do it so often? This is the only phone I've owned that does that.
Any idea what's going on behind the scenes (either on the phone, or at AT&T) when the phone pops up that "refreshing sim data" message? What's refreshing on the sim or the phone, and why does it do it so often?
On an interesting related note. The sim I am using is from my iPhone account on AT&T and is grandfathered in with the true unlimited data plan. What's interesting is that usually when I put the sim into another phone, like say my old Razr, the AT&T website almost instantly reflects that I'm not on an iPhone with that sim at the moment; with the i9000, the sim's been in it non-stop for almost a month now, and AT&T still reports me as an iPhone.
get this too, what is this?
I'm still getting this...
No one has any ideas? I've noticed that AT&T Web site now reports the phone as "unknown" but they haven't monkeyed with my grandfathered unlimited iPhone data plan (yet).
I get this on my captivate too. It happens on both Perception and Assonance roms. The only other thing I can think is that I have an old Cingular 3G sim card so maybe that is acting funky with it.
Anyone figure anything out with this?
I'm starting to get this too ever since I installed the Pheonix Rom on my Captivate. Never had this problem before. It even sometimes cuts off service when that pop up shows up.
I just started to see this on the new Cognition 3.0.4 rom for the captivate also. Any ideas?
I'm seeing it on my Captivate with Perception 10.2... I also have the old unlimited AT&T iPhone data plan. When I log into AT&T, it shows I am using the Captivate.
One more here. Paragon RC5 didn't do it but RC6 does. Phone is a Captivate with an iPhone sim card and data plan.
I started seeing this to when i started using JS8(my own) and see it using Darkyy's JS8. I only see this when I have my usb unplugged.
Possible rom has wrong CSC for the network you are using .
I have a manually entered network as its not on any CSC sim pops up and i just choose O2 UK as its the carrier for the network i use .
Result no more pop up .
Or change CSC to cover your current network .
jje
Hi.. I tried to select the network manually and the "Refreshing SIM Data" pop up stopped popping up.
I think as JJEgan said, it is the wrong CSC that is causing this pop up.
I have a locked SGS2 to 3 UK, which I unlocked and is using it in India with a different carrier.
You guys could try selecting the network manually. It may not be a problem if you are not travelling very often or going out to a different carrier circle.
sounds like a problem, ive seen on other phones, i got it too on my galaxy s when i first got it on stock rom was 2.1 update #1.
is there actually a option to show/hide sim service messages like some nokias have? this is only a suggestion/idea of-course not sure if the galaxy has this option
I have an unlocked galaxy s3 that I bought from the UK. it isn't rooted and uses the sim card from my rooted streak and, before that, from my FUSE. U.S. A&Tt. that's supposed to read AT&T. in this Galaxy, I run only the samsung stock upgrade (2.3). I have had this message from the first day I turned on the unit--approx every ten minutes all day long. if no one on the xda forums can solve this problem, then it's unsolvable.
Got internatial version of SGS2 and on AT&T, getting the annoying message from day one. After reading the article, I decided to choose network manually, but there wasn't any manual selection menu. So after network scanning, I saw two (strange?) AT&T network popping up and selected one of them and now the pop up is gone for now. I feel awesome with it gone.

I was mistaken. The message kept coming up. So tried to fix network to wcdma only and testing. No message pop up in 3 hours. Wish me good luck.

"Refreshing Sim Data" annoying pop ups in SGS 3
Hello all,
I just bought SGS 3, 2 days back. After 1 day of impressing me, it popped up this irritating msg "refreshing SIM data". After trying all the solutions which did not work in my case, found out a new solution.
Try this,
Settings → More settings → mobile networks → Network mode → (select) GSM only
In my phone GSM/WCDMA (auto mode was selected).
BINGO as soon i made this change, the pop-up stopped
Write to me if this helped you.
When on 3G , it need GSM/WCDMA , so its not a perfect solution ...
So, vinodbluey, if you're still around, did your fix work permanently for you?

Atrix HD - Having intermittent signal loss using Straight Talk.

The wife and I have Atrix HD phones that we bought used but in great condition a couple months ago. We purchased the Straight Talk at&t compatible micro sim kits from walmart.com and set up our service. We previously had Samsung Captivates also on Straight Talk and they worked flawlessly. I put in my APN settings and I get data and MMS perfectly but occasionally I get a red triangle where my signal bars should be and my phone says "Emergency Calls Only" and I will wait 30 seconds or so and my signal returns. There is no steady decline in signal that leads up to this. It goes from like 4 bars to a red triangle with a cross inside it.
I live in a fair sized town and have always had 3 or more bars of at&t service with phones in the past so I do not think its an issue with poor coverage. I am attaching pictures of my APN settings.
Any help would be appreciated.

I'm having the exact same issue since switching to to the 4G LTE micro sim. It only seems to happen on mine when I'm connected to Wifi though. I get the red triangle intermittently. This never happened to me until I went from the old sim to the new one. Can't find anything on it yet.
same thing
The same thing is happening to me here as well but using a Net10 LTE sim card (same as straight talk basically). I notice it the most after I complete a phone call. It takes a minute or two to regain service again. This is really annoying. Would like to see a solution to this problem.
So I worked with Straight Talk support for about 5 days, back and forth, bounced to several reps throughout and nothing substantial has come of it. It seems a little better after they made "adjustments" to my account as they put it, but I still get disconnected from mobile data when on wifi.
Don't get me wrong, their support people were very responsive and seemed to genuinely want to help me, but in the end they said "your ticket has been open for more than 24 hours so it has been closed. If you continue to have issues please open a new ticket." Anyone else have any luck on this?
I also was having this problem found that if you edit existing att apn (phone needs to be rooted)with sqlite editor it seems to work fine.
tether also works fine this way.I am still not able to get lte to work with straight talk even with new sim.
Just to follow up. As usual, it seems with ST support, one rep tells me they have some things they can try once I call back on another line and then I get a new rep who says nothing can be done until 10 people complain about the exact same issue I'm having. I'm assured this is an isolated incident...
I went ahead and purchased a new SIM card (looks different than the first LTE card I had) in case I had a faulty SIM. Worked flawlessly for a day and now it's back to the same issue of cutting out completely throughout the day.
same problem here on wifi get red triangle (especially after phone call).
More since i switched from 4g sim card to lte sim noticed that data disconnect from time to time like make impossible to watch video flawlessly...
with old 4g was yes only 4g but never loss a bite....could watch anything also streaming tv.....now it is impossible.....
the end of the month going to switch to old sim and see if the problem is in the new sim cards they tried may be to limit access or is in the new service doesn't matter what sim card you possess..
we'll see...

Switching to my old sim was my first thought to. However when I tried it didn't work. I called ST and they informed me that once you switch sims, the old one can never be reactivated. On top of that they don't offer the non LTE sims anymore. Such a pain. Hope you have better luck though.

Some one could correct me if I'm wrong here but I'm pretty sure this is a result of ROMS using a 4.4 rom. Modem crashes. If you want to test it run a Stock ROM... If you are already using a completely stock ROM then Idk what to tell you. But same thing happens to me using any version besides stock. And yes only when on WiFi

Then unlock your bootloader and try flashing different radios from the different stock fastboots we have. Depending on the fastboot I can have next to none or almost full in my bedroom. For me, ATT JB is in the middle, JB Mex Retail is the best, Bell ICS is the worst. ATT ICS was about the same as ATT JB.

For the time being, I just switched to Aio and so far so good with LTE coverage and no disconnecting issues. If they return I'll try different radios as you suggested.
So I've been with Aio for about a week now and everything is working great (knock on wood). I've had 2 mobile data drops at work with Wifi turned on, but they only lasted for a second and I do have really bad reception here inside the building. Outside of that no issues at all so far. I'll update if anything changes.

[Q] SIM Info gone

So I lost all info on my SIM card. No MEID, carrier info, phone number...everything. I kept getting a "no Sim card" "cannot connect to LTE". So I started messing around in my phone pushed buttons I shouldn't have and now I'm forced to do the one thing I don't ever do...ask you guys for help. I have been able to answer every question I've had by searching posts. Not this time. Can I pull the info for my sim card from a previous backup of my phone? If so, where would I find it and how and where would I place it in my phone to restore what I am missing?

Is it a sprint HTC one? If so, and your phone is running besides the SIM no detecting, I'd call into sprint and see if reprovisioning on their end would help...the SIM is strictly for the lye connection, it may have failed which if it did I believe you'd have to get a new one from sprint and have it linked to your account/phone in their system...I had similar situation except my issue was that a different SIM was linked to my account/phone which caused me to not have lte data til sprint changed to the CCID (a tech support rep will know what to do, it's a pain but it can be done) that was currently in my phone. Hope that helps. Let me know if that got ya somewhere.

[Q] N6 - No incoming & outgoing Calls, mobile data gone.

Having my Nexus 6 for almost a month. Things working perfectly in the starting(or after reset), but after two or three days, No incoming calls, no outgoing calls. No mobile data. Cant realy tell it as a mobile sometimes. Wifi is working good always. After reset, it is working properly for two or three days. Whenever it is not working, I am able to see a !-mark near the tower bar.
My mobile always connected to 4G when no wifi.
No Custom ROMS and no root. Plain Android given by google.
Anyone having this issue. Any suggestion?
Go get a new SIM.

I was begining to think i was the only one who had this problem!
Yesterday morning i woke up and to my suprise my signal bar had a (!) it it but it was still displaying my regual signal level.
I switched my wifi of and i couldnt get a data connection just the (!) sign. I got my girlfreind to give me a ring and see if a
call would go through which it didnt it just said that i was unavalible. I then desided that a reboot might sort the problem
but when i my phone booted back up i was presented with the holow triangle signal icon to say that i had to signal. I then
popped my simacard out thinking it could have just been a bit of dust on it. I gave it a little bit of a dust of and popped it back
into my phone and i was given the same no signal and emergency calls only yet it was picking up that there was a simcard inserted.
The day before i had flashed the alpha version of PA so my next thought was that this would be a ROM bug and went ahead and
flashed chroma which i was using prior to PA and i had had no issues with. Held my fingers crossed as it booted up but much to my
dismay i was greated with the same no signal problem but i went into the settings and searched for networks. Three was one of
the network it had picke dup so i tryed to reconnect to it but i got the toast to tell me i couldnt connectto the network and to
try again later. I checked the APN settings and it had automatically grabbed threes APN from the sim card so at this stage i was
completly baffled by them problem.
My next move was to try my sim in my girlfreinds phone and what do you know it worked a charm. As a last shot to check everything
was okay and i was upto date on my bills etc i gave three a ring and they told me there was nothing wrong with my sim and everything
was working as it should be and that it was a problem with my phone.
That brings me to the point i am at now completly baffled as to the problem and slightly angry at the 2 week old phone that had been working
perfectly up until now has suddnely desided to stop with no warning.
So you are not the only one and i expect their are more of us. I am going to flash the offical stock rom from google and see if that does the
trick but im not holding up much hope i feel like im going to have to contact google and find out where the problem lies.

i reverted back to complete stock using the image from there site to no luck so i relocked the bootloader and took it back to the carphonewarehouse and they straight swapped it for a new one which is working perfectly
My sim died after a month. My calling went out and then only lte worked no 3g. Got card replaced and it works perfect now. I have US Cellular.
I've posted this in few other threads also, but I had also problem where I only had tgt exclamation mark no matter what I did. I solved the problem by waiting like 5sec before inputting my pin-code. If I input my pin code too fast after a boot, it will open my phone, but won't give me cellural network. This seems to happen in every ROM I've tried
Hi,
Solved the issue. Working fine after enabling request for SIM Pin and set my sim pin.
Usually i disable sim pin lock to have uninterrupted boot. But with ROM this is not working.
Enabling SIM pin request solves the issue.
Is this problem with carrier or Android L?

I have not seen this issue on three devices I've owned with Lollipop. So it appears to be a carrier issue?

Lost mobile data with an exclamation mark, I can still make calls.

Edit: added details.
I have had my Nexus 6 for 3 days and first installed my Straight Talk SIM yesterday. Everything worked fine for less than a day then I started getting MMS picture messages failing. Now I get no mobile data. I swapped my SIM with my wifes, also on straight talk and mine with hers and I get the same issue and mine works fine in her phone.
I have rebooted many times, I have checked my APN settings and even have tried alternatives.
I have done a few searches and see other have this or very similar issues but I have not found anything that fixes my issue.
I am running Pure Nexus with the stock kernel.

Straight Talk.
Pure Nexus ROM
I did a back up and tried flashing another ROM last night, CyanogenMod but I did something wrong and I ended up flashing Pure Nexus again and it restored everything from my backup (still learning I guess). But it is working fine, now that is, it was working fine before. The only thing that I thought may have caused an issues was I had Macrodroid setup to disable wifi radio when out of my homes cell tower's range. I used this all the time with my old phone and it helped a lot to save battery. But it didn't seem to work for some reason. So I turned Macrodroid off and it did help with my data issues then I even uninstalled it completely.
So bottom line, it's working now, but like I said in my original post, it was working for about 24 hours then I started having issues.

I think all know this detail by now. The APN however is unique straight talk even though it is technically AT&T or (T-mobile)
I can't believe this is still an issue, totally unacceptable IMO
I've had this twice today. 100% stock, no root. Latest T-Mobile 5.1.1 with T-Mobile service. I'll take my phone out of my pocket and have a "!" next to the signal bar.
This even happens when in use. I had Spotify streaming music in my car when it cut out. When I got home, I checked the phone and again, "!" next to the signal bar.
I just did a clean flash and factory reset yesterday and set the phone up as a new device (no apps auto downloaded from previous setup) and I'm still getting this error whenever I leave the phone to sleep too long.
Same here !
Bought a N6 as my first Google phone, I thought I'd get the benefits of an always up to date phone, but instead I have to deal with that kind of issue
Hopefully that's a software issue and Google will provide us with a fix quickly... that's why I bought a Nexus !
(Orange 4G - France)
I had the same thing happen to me today. I left my phone in the car to go to a meeting, went to check it had no signal. Just turned on airplane mode for a few seconds then off, everything came back. I'm using the phone on ATT GoPhone network. I'm also using the nextgenphone apn instead of the phone apn. Maybe that's causing it.
