Simcard isn't detected sometimes - Nexus 5 Q&A, Help & Troubleshooting

My already 3 years old nexus 5 is working great, except that I have some troubles with my simcard. My phone isn't detacting it sometimes in the middle of the day, without any proper reason and then I have to restart my phone several times to make it work again. I already tried taking out the simcard and putting it back in but it isnt really helping. I also have the problem that my phone isn't really accessing the internet. Even though the 4G symbol is there I don't have a connection, the only thing that helps at these moments is to turn on and off the airplane mode, that way I can access the internet for a quick time, enough to refresh a web page or send some whatsapp messages. I already tried to tape that area where the simcard is placed to make it more stable, without any success.
Does anyone have an idea what to do? I don't really want to buy a new phone since the n5 is working great for me.

Hey,
had exactly the same with my N5. Not sure if it's related to a securtity update or not. I was not able to get it work again. Probably it's getting worse for you with time. There are some threads around xda dealing with this problem, but - at least for me - there no solution yet.
regards

Same problem here since a few weeks.
If you have updated the radio to the last version, and if you have already tried and got the same issue with another sim card, then it may be a motherboard issue.

[Q] complete signal loss

Iv had the AT&T One X since the 4th and so far I love it! I haven't had any wifi issues or bootloops or anything, the only problem I'm having is the phone will randomly lose signal completely (0 bars, little x next to the signal) and wont get it back unless I put it into airplane mode and turn it back off, or reboot the phone. In the 6 days Iv had it it's lost signal 3 times, once on the road where I normally get at least 3-4 bars, and the other 2 happened at some point over night while I was asleep. Has anyone else been having this problem? Also do you think it's a software/radio problem that can be fixed in a update, or would it be hardware in which case I should take it to the store and exchange for a new one.
I've had this problem myself. Had the phone for 19 days now and I think it's happened to me 3 or 4 times.
I can guarantee it's fixable with a software update, even if the problem is hardware-related. At the very least, the software could detect the lack of signal and automatically cycle in and out of airplane mode to fix the problem without user interaction. But I'm sure whatever fix we get will be much more reliable than that.
WHEN we get the fix is another question...
Thanks for the reply. I figured it might be a software issue since you can cycle airplane mode and get it back and I don't really want to take it down to the AT&T store for an exchange in fear I wined up not able to set up gvoice or start getting wifi issues and the like lol. so far the signal drops are far and few in between making it an annoying issue rather than a critical one, and I read we've got root now so even if HTC/AT&T twiddle their thumbs and pretend nothings wrong I'm sure the community can save the day lol
I would swap it out Azure. My first HOX did exactly this, and I saw it reported elsewhere on a number of other devices. To me that says it's most likely a bad radio flash on some handsets. I suppose you could try and flash the RUU that was posted, as it most likely includes the radio as well.
I got tired of all my calls going directly to VM without ringing. And not being able to send out texts. My replacement works much better (or rather, how it should've from the beginning).

Was this problem intermittent?
My phone has been doing this randomly, except it never went to voicemails, just hung up after like 30 seconds.
Wondering if I should switch it out also.
Had this problem for a day. Took my phone to the at&t store and they changed out the sim card and I haven't had a problem since.

I never thought about the sim card being a possible problem...might run up to the store when I get the chance and swap my sim out and see if that fixes it, if not I'll just swap the device out and hope all's well
The CSR actually swapped a new micro sim first, since the one provided via online sales was an older one (most likely from the iphone 4/4s batch). It didn't seem to fix the problem though.
And yeah, the problem was very intermittent. One second it would be working fine, and the next it would show the "x". Sometimes the bars would come back immediately, other times it wouldn't until I rebooted or cycled airplane mode. Luckily it happened while I was at the store; it's much easier to convince a sales rep to swap a phone when they can witness the issue(s).
Yeah it's only happened to me twice since I got it on the 4th... it'll be very hard for me to convince them that there's an issue haha... maybe I'll head down there if it happens at a time when I'm not in class or something. I'm sure if I mention returning it/their policy I'll get a swap.

next time my phone drops signal I'll take it into the store and see about a sim swap in hopes that'll fix the issue if not then I'll reluctantly swap the unit out (I've grown rather attached to this one xD)
**EDIT**
strange...woke up today and my phone completely lost signal again, normally there's a few days between each event but this is the first time it's happened twice in a row =\
So it happened again, I'm going to go get it switched... but it says on the Mobile network section of settings, "Disconnected because service is unavailable."
There is clearly almost full signal strength, and I have never been without service where I live.
I was expereincing constant network drops all of yesterday due to an outage. However, it's back to normal for me today. So it may be possible there's an outage near you as well.
I think it is more AT&T than your phone. I was in down town buffalo at a swim meet with 5 bars of hspa+ on my blackberry bold that has a great radio. I had data but it was slow dial up slow. There were maybe 100-200 people at the meet and it was at a community college. The only other time I had this was when I was in a car that was driving by the buffalo bills stadium. Voice worked but I had no data. I guess too many people using their cell phones.
Definitely not AT&T, my SE Xperia x10 worked perfectly fine, never had any trouble with signals.
I also encounter the intermittent signal drops on my 4 days old AT&T one x.
It seems to me that the One x doesn't hold signal as good as the iphone, my 4 and 4s usually get around 2 bars in some really remote locations of the building I work. But the One X just drops signal completely. I'll see if I can do a sim swap like some others suggested.
I'm starting to think it could be an issue with lte phones because the same thing was happening to me on my galaxy note with 2 different sim cards and 2 different devices and now it's happening on my hox

it has happened to me 3 times in 5 days. All 3 times I was either:
1. in a poor reception area and it came back on its own, i did not have to use airplane mode.
2. was using BT streaming in car and using car charger, once car charger was unplugged, signal came back.
One X has issues
Definitively problems with the phone.
I have three.
They just drop signal completely. One will work, the other will not. Only way the signal will come back is if you turn the phone on and off again. I love everything about this phone....except it isn't a very good phone.
Also, typically when I turn the phone back on, that is when I get my text messages. Nice.
Yeah I figured out it happens when I lose signal (a couple buildings on my schools campus don't get reception), and then the signal won't come back until I reboot or airplane mode.. this is after a sim swap.
Oh and do I need the box my phone came in to swap it?

I have had this issue as well being on the Rogers (Canada) network. I started a thread as well and my theory is there may be a hardware issue reading the SIM cards.
Every now and then I get a "preparing SIM" message pop up on my screen. Also, I lost signal once and in frustration I slapped the phone into my palm VOILA! signal came back full.
This is the second One-X I've gotten from Rogers so there may be a design flaw somewhere. The problem is this behavior only pops up intermittently and cannot be recreated at will. This makes troubleshooting very difficult and practically unprovable in the eyes of providers.
Hopefully there are more reports of this problem and the carriers push back on HTC to resolve the problem.

[Q] Problems with Skyrocket disconnecting when turned on

I recently bought a new Skyrocket and after I installed an ICS leak and rooted it I lose 4G and MMS not long after I turn on the phone, and have to restart several times until I get lucky and it may work for about an hour or two.
So far going back to stock GB or even the official AT&T ICS hasn't fixed it. I read about the efs folder being corrupted but it still shows the correct IMEI so I doubt that that is the issue. My SIM card also works in my other phone and other SIM cards work in the Skyrocket. Right now instead of thirty reboots with no luck I can stay connected for about a half-hour until I need to reboot again. I am aware that other people have had similar issues but I see no definite solution that applies to my symptoms.
Also, I have noticed that if I disable data and reboot MMS will work fine until I try to use data again and then I'll get nothing.
The problem seems to have automagically fixed itself not long after I posted. I'm still curious as to how it happened or if it happened to anyone else just in case it happens again.
Perhaps I spoke too song. The phone worked fine until this afternoon. An additional thing I noticed however was that while listening to music the audio stops at the same time that the signal disappears. Perhaps the fault lies in the kernel?
I read into changing the APN from PTA. That didn't work either.
There has to be someone with the same problem.

Signal Dropouts

hey!
I have a problem with my One Mini. I have constant signal dropouts. Phone calls stop after a second, also losing data-connection all the time and always seeing the message "Preparing SIM-card".
It feels like my phone having problems with some mobile-cells. Usually I have to try to call someone 3-4 times, and after 3-4 attempts I can talk normally without getting interrupted after 1-2sec - like my phone found the correct cell or something like this.
I tried
- my second (O2) sim-card
- put some tape on top of the sim-card (solved this problem for people with different phones)
- put some signal-tweaks in my build.prop
- changed network mode (WCDMA/GSM/LTE...)
but nothing helped.
I am on O2-Germany for many years and never had those problems, my One S was working fine (before it got bricked )
Had the same problem last month in France...
anyone else having this problem? could this be kernel-related? I'm using JMZ`s kernel. But I guess this is more a radio-problem, or?

I haven't had this issues, in fact, I went camping last weekend and most of the time I was able to get 1 bar when everyone else didn't have service at all. I'm using the AT&T variant on AT&T with the WWE DeOdexed Stock ROM and Jmz's Kernel 09-04-13. I attached a picture of my kernel, baseband, build, ect. I'd suggest making a backup and restoring your phone to stock to see if it's a software issue.

Sporatic Mobile Network Connection

I got my Nexus 5 a few weeks ago and I'm really loving it, but about 5 or 6 days ago it started to randomly be unable to connect to my network for the first few minutes after rbooting my phone, and then just random intervals of 5 or 10 minutes of being unable to connect to my mobile network at a time (my telecom is Rogers, I dunno if that's relevant). and it appears to be getting worse as time goes on (that admittedly could just be in my head). I use MultiRom, so first I tried using my secondary ROM more often to see if it worke without issue or differed in the severity, scope or conditions of the problem, but I experienced the issue exactly the same. Next I swapped my primary and Secondary thinking that would somehow help... still no dice. Today I flashed a third ROM and it's still an issue. From this I take it that the issue isn't ROM one, so I'm stumped. I'm almost positive that my bootloader and radio are up to date so I'm up against a brick wall. Has anyone else had this issue? Or have any clue what I should try next? I know without a LogCat this isn't something easily diagnosable, but it's late and whatnot, so in the time being I'm mostly curious if this is a regular or known problem that I'm unaware of/ my searching somehow failed to turn up? Anyway, any help wou;d be much appreciated, but thanks to those who even so much as take the time to glance at this. Cheers!

Antena Problems?

Hello! Tonight, it appears that there's something up with my phone. It informs me that I can only make emergency calls and I can't make calls nor send texts either even though its showing me five signal bars. I have to reboot into safe mode then back out again in order to get it fully functioning without hiccups.
I've searched around for a couple of hours and saw that people are reporting some hardware fault. Although they also said that their phone was unable to search for available network operators in their area. Unlike theirs, mine is able to search for available network operators.
Is it possible that the charger I'm using is causing problems? I'm using my dad's Zenfone 2 charger brick with my original samsung cable. I've ordered an Aukey quick charger though.
Is it also possible that the phone's gotten quite hot that it's already messing and needs to cool down? I've flashed a bunch of times since I was trying on some of my mods.
My phone's a K variant and it's been rooted for quite some time so that's not the case. I've also tried inserting my sim card in a different phone and it seems that my sim card's not the problem as well. I hope my phone's just having a bad evening lol.
Any ideas on this?

The only thing I can think of outside reinstalling roms and what not is to flash a newer modem only, on the handset. I honestly can't comment on if the charger could be the issue
It sounds like a software issue, not hardware, as you can get it working. I'd flash your latest stock, then factory reset and see what happens.
