No Network After Phone Reboots - General Questions and Answers

My phone is a Motorola XT1032 and when I reboot it instead of going through the routine of SIM lock PIN then phone lock PIN, it just goes straight to the phone lock with no network connection.
This firstly occurred at work yesterday when distractedly I ended up in "Safe mode", which doesn't work for me in any case as there's a bug or whatever somewhere which is by the by. So after rebooting a warning triangle and exclamation mark was showing in the status bar where it said...."Your selected network (3) is not available", 3 being my network in the UK. I then did the obvious: removed the SIM, gave it a wipe, remounted it and hey...network back!
I was a little concerned that perhaps the pins in the SIM card housing may be faulty so to check I rebooted my phone later on with exactly the same result and the same solution by remounting the SIM. Totally bizarre, so anyone have any ideas?
Thanks in advance,
Malc

[Q] SIM card error! Please Help

So out of nowhere today, i awaken my phone and I see an error "SIM card removed, reboot phone" I reboot the phone and now I have no signal and a SIM card symbol in the notification bar. I didnt remove the SIM so I dont know what happened or how to fix it. Anyone know how to fix this?
EDIT*** Nevermind. I removed the sim, then put it back and that solved the problem. Probably should have tried that before posting lol
happened to me a week ago. I was puzzled. I removed the sim and battery at the same time like 10 times. So I flashed back to stock and took it in. The guy plugs the phone in (probably checking for root) and then unplugs pulls the sim and battery and turns it back on. All working like nothing happened.

Suddenly No service some time after root

So got this shiny new phone and decide to root it for adblock etc.
The root went fine, I used the Xperia-L root zip not the chop--- something. So a while after that, maybe a day or two suddenly I get a No Service.
I went into Settings-Mobile Networks and try to choose the network manually, I couldn't, I can move through Auto and Manual but when I select Manual it always goes back to Automatic. Can you guys confirm that that settings doesn't work? Can you choose Manual instead of Automatic?
Then the phone scanned for available networks and it found my home network relatively easy...
NOW selecting my home network gives me the error "Could not join network right now. Please try again later"(or something like that). A minute after that a toast message pops up "Registered on Network" but I still get no service...
Anyone have any idea? I thought Sony phones are root friendly with them sponsoring CM and all....
I have tried everything. Unlock, relock bootloader, restored TA...flashed stock firmware....taking the sim card out while power is still on and inserting it again.....
So frustrating, thanks for any insight....:fingers-crossed:
It happened with me..
What I did is,
Switched off the phone
Removed SIM card
Restarted phone
Again switch it off
Inserted the SIM card
Restarted the phone..
It worked!

[Q] Stuck sometimes while unlocking sim, and strange "error" in status bar

Hello. Sometimes when I turn on the phone and unlock the SIM with my PIN, it just gets stuck in the unlocking SIM message. The phone gets signal, even internet access, and I get notifications, everything runs OK behind, but I can't use the phone because that message is there in the middle of the screen. Not even enabling airplane mode fixes it, I have to reboot. I haven't tried removing the SIM, though. I recently wiped everything > flashed a factory image > flashed cataclysm > flashed franco BUT it already happened before and keeps happening now.
Also, sometimes I see a strange error in the status bar (more often when the SIM problem occurs? dunno). In Spanish (the language the phone is set to) it says:
"El acceso restringido se ha modificado"
Which in English is, more or less:
"The restricted access has been modified"
When I pull down the notifications, it's already gone, and the phone keeps working perfectly
I can't RMA it (it's not officially sold in the canary islands, well, it is via amazon but when they announced that it was too late), so I hope it's a bug. Any ideas?
I think it would be useful to know that it's a real microsim (not a cut-down SIM), a movistar one, and I don't have any other microsims to test or other phones that use microsim. The phone is from the UK.

No service [SM-920I]

I can't get a signal on my phone. It keeps showing the "emergency calls only" message. When I try to call someone, it shows an error message: "network not registered".
Weird thing is, it was working flawlessly a few hours ago. I didn't mod it, nothing is different. I just charged it and rebooted.
I tried toggling airplane mode on/off, factory reseting, and it didn't fix my problem. My IMEI shows up correctly on settings, and the phone is being used in the same region I bought it.
OBS: If I put the sim card on another phone, it works. When i put it back on the s6, it keeps working until i reboot it, and after that it doesnt register on the carrier network anymore.
Anyone can help me with this?
No one?
I've exhausted all my known options! I can't keep a phone that can't even be turned off. If the phone freezes, that means I'll not have a signal until i can find another phone to put my sim on, and then back again on mine...
I'd really appreciate some help, since support where I live is crappy and chances are that i'll have to take the loss on the defective phone if I can't fix it.
Went to the carrier, tried other sims, even other carriers sims. Still nothing.
You can't get warranty from who you bought it from or else samsung? it sounds like a defect somewhere, if you are lucky it could just be the simcard tray but else it is something inside the phone

Nexus 5 SIM not recognised

People,
I hesitate to ask the question again, but I promise you that I've read everything on the subject that I can find (including many of the 171 pages of the "Nexus 5 Flashable Modems and EFS Backup" thread...) and also on a lot of other sites.
My son's N5 on 5.1.1 ran out of battery a month ago (it worked perfectly for the 15 months that I had used it) and when he recharged it he'd lost mobile data. He had the mobile service triangle in the notification bar, but empty. No service.
I have tried absolutely every suggestion that I've read. Airplane mode on/off. Flashed 3 older radios. Installed older Lollipop & Kitkat 4.4.4 from Google Nexus factory image site. Installed the latest nightly of Cyanogenmod. Installed MPZ79M. Rooted it. Nothing works.
I don't believe it's a hardware problem - when I remove and replace the SIM the notification goes from the square with a diagonal bar across it ("no SIM") to the empty triangle. But as soon as I reboot (not just screen off & waken, but full restart) the triangle is replaced with the "No SIM" square again. The same reaction happens on the initialisation after a factory reset - at the "Register SIM" screen it says "No SIM", but extracting and replacing the SIM starts the "Attempting to connect to service" sceen, though this just does nothing until my patience runs out and I skip it. The SIM itself has 3 scratches along it, so all in all I don't think it's a contact problem, but something in the software. The SIM works fine in the Nexus 4 that I've given him.
EFS - I don't know enough about it still, but the phone displays the correct IMEI, so I'm hoping that this means that the EFS is not corrupted?
I know that this is a well-known problem, but on the off-chance that somebody has read a solution that I haven't found...
Thanks for your patience and any help you can offer.
Oh well...
...I guess I have a £350 paperweight?
I suppose at least I can use it as an entertainment console, since wifi seems to be ok. But a terrible shame to waste such a beautiful device.
Maybe you already tried it... Just to be sure:
a) You have incorrect APN configuration, to solve this try resetting your APNs via Settings > Wireless & networks > More > Mobile networks > Access Point Names and then click in three dots above and select "Reset to default".
b) Your mobile phone antenna unit is not working properly, solving this is pretty easy, shutdown your phone, remove your phone's back panel very carefully (using a plastic material..i did it using guitar pick) and then you'll see two wires adjacent to edges of your phone, just remove and refix them gently and reboot your device.
c) Reboot in safe mode and try to play with the preferred network type.
d) I had this problem "No service and no signal network in nexus 5" after restarting phone.
I tried to restart phone few times again and reinsert sim card. No luck.
Then I took sim card out while phone was on ( I forgot to turn it off) and reinsert it and now it's working fine.
It must be a contact problem. Just not shure how long will it work.

Thanks, Primokorn, I'll give your suggestions a go - appreciate the ideas.
I have tried the APN settings, but since there's no SIM (huh!) it's greyed out, though it's temporarily updateable if I extract/replace the SIM while the phone's on - but it's grey again on the next reboot.

Primokorn,
No luck. I tried all of these with no result at all. It looks as if this is a very serious flaw in the Nexus 5 - I had my doubts, to be honest, when my son said it started after the phone ran out of battery, but I see exactly the same explanation from other people in the huge number of threads reporting this no-radio problem. How can Google issue such a good phone with such a lousy bug in it...? No point in even asking them (though I've seen at least one person who tried with an impressivly helpful response from the Google support person) since not only is the phone out of warranty but it has been rooted.
Oh well, I enjoyed it while I had it...
