My DNA just has the Voice service after connecting to WiFi over night. The first thing I need to do after leaving home is flight mode on and off to get the phone back on the carrier's network data. It is annoying, Am I the only one here?

I get the same problem. I have also experienced "preparing sim card" messaged several times. I hope the OTA update helps, I have not had the chance to install it as I am currently studying abroad.

Have you tried in gsm only mode? I have same problem and preparing SIM card issue doesn't come up in 2g mode. I was reading this kind of issue is produced most likely by a faulty 3g antenna.

I experience this problem frequently too. Not sure if there really is a fix for it. Toggling between airplane mode works for some people, reseating the SIM card, gently erasing the back of the sim card, applying 2 layers of tape to the sim card tray to keep the card seated appropriately, exchanging for a new SIM, putting phone into airplane phone and removing sim than replacing sim card, remove sim card than boot into recovery and clear cache and dalvik, etc.. yes I've tried most of these but to no avail. The OTA update may have helped a little I am not sure. Most believe it is a hardware issue that really can't be permanently fixed. If anything else is found let us know. Such an annoying problem that totally ruins this amazing phone.
There's different issues being discussed here. It sounds like you're having the issue where you need to toggle airplane or network sometimes when switching between networks or from WiFi to mobile data.
It's not device specific, there's some decent articles on it and in the early days we thought it was a Verizon issue. But it's actually a Sprint problem too I learned on accident when I was trolling their forums.
When the network is activated, on a device with a SIM card on Verizons network, the preparing SIM notification is actually describing a process very similar to *228 back in the olden days before LTE that was done when first activating a device on the CDMA network. The LTE network is different in that everytime it connects to the network is does that SIM activation process.
I know on my networks here, there's a changeover in one place it happens about 50 percent of the time.
If that's what is happening to you and toggling airplane fixes it, I think it's an LTE/network symptom and not due to a faulty device.
However I have a device I'm about to warranty with a hardware failure I'm thinking. It gets data great but absolutely no voice ever, never had an incoming call or anything. Or made an outgoing call in the month I've had it. It doesn't bother me I didn't buy this thing to talk on, but I'm donating the device so I'm going to have it fixed.
Anyway, from all the OP has posted so far, I'm not feeling like it's a hardware or device issue, however as more info develops that opinion may evolve.

U r the man Charlie. I am having an identical issue as op. And based on occurrences relevant to location it seems that this is only an issue when under 4g service-atleast for me-. Toggling airplane mode reactivates SIM as u said and restores full functionality. However, I have noticed the time needed to pass for said issue to reoccur is significantly shorter unless a full restart is preformed. If fastboot is enabled the issue persists. My question is this; if this is a network issue -which I'm sure it is at least in part- what software wise -if anything- could be going on a full restart fixes?

I'm a gsm user and I'm having the issue in a non 4g lte network. I have preparing SIM card every couple of minutes. If I toggle to gsm only mode everything is perfect, not even a single issue. Looking to the logcat, when the error comes up, it shows a message about ICCID number doesn't match stored one and then invalid radio technology. Is this software or hardware? I'm really confused. I've already tried everything from software side, kernels, radios, roms, RUU to stock.

Ok u flashed a rom and have No SIM inserted or no service or that kind of error.I found this fix trying out things for myself.Take out your SIM card ,turn on airplane mode,reinsert it and turn off your phone(not reboot but power off).Wait for 1 minute and power it back on.Tada!Should be fixed!:fingers-crossed:
Thank you!
Thank you so much! I was worried I was going to have to try one of the more complicated fixes I've seen here. I was puzzled because after performing Joseph230's procedure to root and "convert" an S4 from AT&T to T-Mobile (http://forum.xda-developers.com/galaxy-s4-att/general/convert-i337-to-m919-wifi-caling-t2896719) everything seemed fine and I reinstalled all my apps. Then, I get the "No SIM inserted" error out of nowhere!
After much researching I was losing hope of finding a fix guaranteed to work. Then I found your post and it worked like a charm! :highfive:
robermaldo
Thank You
Im so glad that this worked because I was losing hope that my imei or something was broken and I git scared then I found this and it actually worked I thought it was because 5.1.1 or something anyways thanks for the help I actually loged in my XDA account just to post that cause I just always use the browser
A coworker brought me his G2 that I have taken apart to fix many times before because it was having problems charging and turning on (black screen; rhythmic buzz from the vibration motor). I worked around that to get it booted temporarily but then the SIM connection seemed to suddenly fail. I replaced the motherboard entirely because some charge/power issues persisted and everything works perfectly EXCEPT that the replacement also doesn't see the SIM. Both are running stock LG Verizon Lollipop (assumed installed by OTA). No one was playing around with alternate ROMs or anything. None of the fixes in this thread help. The SIM slot is on the board so I hesitate to assume that the charge, mic, headphone flex PCB has something to do with it, but it is the only major common component (even replaced the screen again along with the battery, speaker, etc while leaving out useless components). Any suggestions?
Long version:
After a previous screen replacement it would only buzz when attempting to turn on or buzz repeatedly when attempting to charge until I loosened the black screw near the battery connector. I definitely narrowed it down to that particular screw, though I still couldn't say why (the previous tech who replaced the screen may have shorted the battery terminal near there). When he brought it back to me it was doing the same thing again even with the screw completely removed. Within minutes I had it booting just by poking around. Not sure what I did but I had to take it apart and poke around again to get it to come on after making the mistake of turning it off (went right back to buzzing). I'm pretty sure that the SIM card worked because he received a couple text messages when I first got it turned on (phone hadn't been booted in a day). After getting it to turn on I had to leave it on while reassembling, so I put the SIM tray back in when I was done. The owner was watching and asked why the status bar showed an "X" on the signal strength, so I told him that it was because you had to reboot after reinserting a SIM on most Android devices (as opposed to dual-SIM and iPhone devices). Though I couldn't turn off without causing the power problem, I could safely restart. Unfortunately, restarting only gave me the "Insert SIM" message at boot and nothing I could do would get it to see the inserted SIM. I tried many SIM cards but none worked. I replaced the motherboard expecting it to be a solution to both problems but only the power problems went away. The SIM card issue remained even though the SIM slot is built into the part I replaced and the part I purchased is supposed to be guaranteed, tested, clean IMEI, etc. I'm at a loss. I've taken out every unrelated component and replaced the screen again and replaced the battery so about the only thing that is common is the flex PCB with the mic, headphone jack, display connectors, etc running through it. Not sure how that could be a factor, but I'm replacing it too. In the mean time, does anyone have any suggestions for what could be wrong?
Update: A new mic/USB/headphone flex PCB fixed it. I'm not sure how that can cause the SIM card to not be detected, but I conclusively tested and that was definitely the problematic component: No SIM card detected on either motherboard with the old flex PCB, SIM card detected fine on both motherboards with the replacement flex PCB.

Hello, is your LG G2 still working with the new PCB flex?
Thanks a lot, this solution worked for me ?
i've done flash rom on Mtv Slash 3G 512 RAM Tablet, but no sim detected ....& i've followed your suggestion but no solution made...!!!
I had spent more than one month using CM13 based ROM thinking its ROM based issue. but this resolved the issue.
But now no sim issue has been resolved yet no mobile signals are working...
I have a vs980 or the Verizon lg g2. It bought it unlocked and I use T-Mobile. The data worked when I was on the stock os. I then got cm13 and everything worked good accept it wouldnt see my sim card or it would say no signal. And it had no info on the sim card in the about phone settings. So I tried a few other nightlys and nothing worked. I went down to cm12 and still I got the same error. I tried what you said here multiple times and it doesn't seem to help. Any help would be greatly appreciated. Thanks

I found a fix! Go into settings and select Mobile networks. When your in there there should be a "preferred network type" change that to global and there you go. Now I couldn't get that to work on cm13 because the settings would crash when you try to go into mobile networks. But I got it to work on cm12 just fine
dear sir.

THANKS!!!
I've spent the last three weeks dealing with various radio bugs and issues, clearing preferences, wiping caches, factory resetting, and installing clean ROMs. All it took is to set the thing into airplane mode? You've got to be kidding me!

sim no detection on leeco le2
Your solution not working on my leeco le2 . please suggested me another solution.
Hi guys!
Hopefully someone here may be able to help.
Recently got a Honor 7 and has been working great, about two days ago I stopped being able to make calls and use data.
E.G. it recognises that I have an 02 sim, then switches to emergency calls only but wouldn't even let me call 999.
The 2G slot works absolutely fine. I cannot find anything on-line with regards to this issue (no fixes anyway).
Its not a major issue as I can at least still make calls and these days there is WiFi everywhere but wouldn't mind getting my 4G back or at least finding out what has caused this issue.
Would be so grateful if someone could point me in the right direction as I am completely stumped.
Tried a factory reset, no luck. Was thinking of completely re flashing the OS onto the phone and starting from scratch but not entirely sure if its worth it.
Thanks guys!

I would definitely be calling your service provider...sounds like tower issues or may even be a faulty or corrupted sim card.

No, unfortunately it is a device problem, Honor service answered me that it is an hardware problem, but I can wait for repair it, so I have got a new H7 Premium and the hold now is the new device of my wife, she doesn't need 4G, by the way if I choose 2/3/4 G the phone if is in 4G often don't have connection, so I put it only in 2/3 G and work fine...
So u got it repaired ?

Hello all,
I do have the following problem which is not new and mentioned in other threads but there is no solution and the threads are quiet old - so I hope it is OK to start a new one:
My LeMax2 is constantly dropping the network signal and the signal is in general very weak (I can only get calls outside, Internet is working irregular "sometimes", outside only. After arrival signal was fine. No difference. Flashed a couple of different custom roms, still fine. Ended up using SmallEUI. After a while (maybe two weeks) signal dropping began. What I tried so far:
- Flashed alternate modem file from SmallEUI, no difference.
- Switched rom back to india20s. Problem stayed the same. -
- Switched to LOS13 (which is still running).
- Entered *#*#4636#*#* switched and set GSM/UMTS band to automatic. Problem got worse.
- flashed various modem files, no difference
- renewed APN settings. No difference.
- Found about 4 threats regarding this problem, can not find a solution. This is exactly my problem: https://forum.xda-developers.com/le-max-2/help/mobile-network-problems-le-max-2-6gb-t3507500
Help? Please? What can I do now?

Have you looked into your carrier? Maybe it's not a device problem..... Try a signal app to see if your connecting to the right bands, getting a good enough signal ....
Have you tried a factory reset?
When I was with T-Mobile they cut service in my area without letting customers know, I ended up buying a signal amplifier for my house to finish out my contract.

Hey,
thank you for your reply. I put the SIM card into another phone and it worked like a charm. So I think it is not the carrier. Rechecked the APN settings also. Regarding the LTE band I am not sure. Most of the time I only get a H+ connection so no LTE band at all. Thing is: The connection was really good with this phone in the beginning.
Factory reset: Yes, and even more (flashed 6 different roms I think and various modems)
Best,
TOM
x829 no signal
i lived in ireland i have x829 from banggood i don't have networking signal strange when i when battery is 0% turn off phone after Charge the battery signal come back for few minutes after again disappear
I have the same problem. I am living in India, and the signal drop is very frequent.
Earlier i only used to get H+, but from few days i get the LTE band but the signal fluctuates almost every second and very unstable - especially the data. The whole mobile network keeps dropping also frequently. Been a pain in the but*
Using RR v5.8 official
This thing solved the LTE stability problem for me:
Type *#*#4636#*#* on the dialer
select phone info
Click the menu on top right on action bar
Select radio band and select band 43
I get decent speeds with some sudden boosts from time to time. PS I am using Airtel in India.
I have the same problem. I am living in sri lanka, and the signal drop is very frequency The whole mobile network keeps dropping also frequently. Been a pain in the but*
i wish to get updates on this problem, cause this is a pain. tried every method mentioned. tried different new roms (rr, LOS, Eui, stock 26s and 21s roms)
Maybe someone has solutions?

Hey, did you have success in resolving the issue?
I had problems too with my le s3 x626, it didn't recognize the sim card anymore, froze, and had to force reboot. Luckily, it was a battery issue. For some reason when the phone goes under 10%, it does that. Easily solved upon charging (happened more than once).
Same issue in the philippines
Heyyo, I'd recommend looking into AEX as @shivatejapeddi recently made a bunch of changes for VoLTE and carrier settings that might help.
Otherwise? It could be your carrier might need further apn and carrier configuration changes in order to work at least on custom ROMs.
Another thing to try? Replacing your /system/etc/apns-conf.xml with this one from the Pixel 2 XL. Download it > reboot to TWRP > mount system > make a copy of that /system/etc/apns-conf.xml somewhere as a backup > replace the /system/etc/apns-conf.xml with the one downloaded > reboot to system > reset apn configuration to defaults to force ROM to reload apns-conf.xml

Solution: Disable "Dual 4G" option in the "SIM Cards & Mobile networks" settings
Hello, good day!
tl;dr: Phone stuck to no cellular signal, until I reboot, restart mobile radio power, or turning on airplane mode for a short while when turning off again.
---------------------------------------------------
I recently bought this phone as an upgrade to my old one. I transferred my sim, and all seems to be working pretty well. I lived in an area with very poor signal reception, so overnight, the phone doesn't have any signal reception other than WiFi.
The problem is that it remains that way (stuck on 'no signal') if it cannot get any signal for an extended period. The problem persists even if I went to an area with good cellular reception even in the city.
The problem seems to fix itself when I placed the phone either by activating airplane mode for a minute, turn off "mobile radio power" then back on again, or reboot my phone but it starts to get annoying over time.
I tried changing the preferred network type to the one my old phone used (LTE/CDMA auto (PRL)) to fix it, but no luck.
Does anyone know a permanent solution to this?

I tried the SIM Reset first and so far it is working perfectly but I need to monitor it first to check if the problem would persist in the long term.
Will update thread on the result.
================
Update: unfortunately, the SIM reset doesn't work. However, I tried swapping the SIM card to see if it makes any difference and surprisingly it did. I put in a SIM in slot 1 from a network with a good signal reception while my previous one on slot 2.
I would like to also note that the current SIM 1 has a successful Xiaomi activation & verified to use the chat features on the Messaging app while the old one does not.
All seems to work perfectly - but need further monitoring I can call it solved. Will update the thread on the result :good:
Update 2: The workaround above doesn't work. I sent to Xiaomi this issue.

My sim is in slot 1. still dropped calls. Seems like network disconnects and reconnects.
When call is dropped I immediately redial and sometimes no network.

Unfortunately, the workaround I posted doesn't seem to work also when my current SIM 1 can't pickup signal for at least 2-3 hours.
Yes I also experienced drop calls most notably when the signal drops below 0 bars (not no signal with an "X").
I can't find a good rationale a factory reset would solve the problem since nothing on my phone (modified settings, modded, or downloaded apps) that can affect the cellular network. So, I won't be taking that road for now.
I already sent feedback on Xiaomi and advice me to send the log files *fingers crossed*
Any updates..?
My father is experiencing similar experience with calls hang and even bad call quality, while pocophone f1 on the same network works flawlessly.
Data problem
I have a problem with my RedMi Note 9 Pro, when I make a call on 4G Airtel network(at least 4 bars) the data connection drops to an average g of 1.2kbps.
I have used the same Sim in the same area in my previous phone the Honor 9 Lite but it doesn't face any problem. Whenever I get a call on that phone the 4G data speed increases.
On the RedMi note 9 pro the data gets completely disconnected and even after I cut the call the data remains disconnected for 2 minutes or so. After that I resumes back. It even gets lesser speeds that my previous phone.
Sometimes the data drops without any reason. It stays disconnected for a minute or so and then tries to connect back. It has got horrible ping.
Anyone facing the same issues?
Having the same issue here. I modified phone settings several times and try with another apps but nothing working so far
I MAY HAVE FINALLY FIGURED OUT A POSSIBLE SOLUTION!
Disable "Dual 4G" option in the settings.
No issue so far for 3 days now
