Hi guys,
I've been having this problem with my N5.
Its a d820 model, unlocked and rooted.
I have no signal, cant register to the network either.
I can use wifi with no problem too.
I changed the micro sim card with other carriers, same issue. I asked for a new micro sim to my carrier too (not cut), but still getting the same problem.
It's worth mentioning that the micro sim works flawlessly. Im using it everyday on an HTC One S and signal and data works perfectly.
When I first get the simcard on the N5, it asks for a reboot, after it comes back up, it shows strong signal, but I can't make any call or receive, no messages either.
After a few minutes, the signal goes down and it shows only emergency calls.
Going into mobile networks and searching for my carrier takes quite some time, but no matter how many times I try to select my carrier,it always comes back with not able to register in the network.
I did a factory reset, and went back to stock, and then performed the system updates to 4.4.4.
I flashed a couple of radios as well, but no luck.
The IMEI shows well, and its the same that shows on the box, so I guess no problems there with a corrupt IMEI.
Has anyone else had any problem like this? Any suggestions?
I've been reading some threads here, and I still have to try a different kernel/ROM, but if anyone else knows of a similar situation, I would appreciate any suggestions.
May be it has something to do wid preferred network...
If u use 3g go to dialpad
Type
*#*#4636#*#* phone info
Select modem as wcdma only...
If u use lte select lte only... See if this works
I think I already tried that, but cant remember for sure
Will give it a shot, thanks
Is the phone second hand?
Have you checked if the IMEI is blocked by the network?
sounds like you bought a used phone that has been blacklisted. if blacklisted, your phone wont work on any US carrier, and many Canadian carriers.
Yes its a second hand phone, and I don't know if it is blacklisted on USA, but Im in South America, so that shouldnt be a problem
And there are no carriers here working with N5 so they cant blacklist the IMEI either
(This doesnt mean that the phone doesnt work here, actually, my wife has another N5 that works like a charm here)

the carriers dont have to work with the n5 to blacklist it. in other words, they can blacklist any phone that connects to their network. as soon as you connect to the network, they know your imei and other info about your phone. anyways, they blacklist your imei, so when your phone tries to connect, it cant. the agreement that carriers have in the US and Canada, could possibly be for all of the americas, or, in south america, they could have their own blacklist.

googling, i found that carriers worldwide are sharing blacklists.
The GSMA, an international association of wireless carriers, also keeps a database that wireless carriers worldwide could check to prevent stolen phones from being reactivated on their networks.

I will check on that, I think I can just call my carrier and ask if that IMEI is blacklisted or not

yup, thats the best thing to do. the people that first answer the phone, customer service, probably wont be able to help, maybe someone in tech. or, use this website to check(there art other sites as well).. http://swappa.com/esn
Well I just checked. IMEI not blacklisted on my carrier, also checked with swappa, not blacklisted either.
I used the *#*#4636#*#* to select wcdma as well as other options there, but still no go.
Also, under Mobile network settings, changed the preferred network type to LTE, 3G and 2G, but no luck
Tried Choose automatically the network, but still getting the message that its unable to register to the network right now and that I should try again later
I guess Im left with flashing some other ROM/kernel to see if it helps, unless someone has any other suggestions

also, what kind of nexus 5 is it, a d820 or d821? it would make a difference signal-wise. ones for north america, ones for europe. honestly, i have no idea which you would need http://www.phonearena.com/news/Differences-between-the-two-Nexus-5-models-D820-and-D821_id48985
I don't know if the problem is with the carrier, since I'm using the very same simcard with another phone and I have data and network with no problem.
The phone is d820, but I know it works here (my wife has the same one), network 2g and 3g work well here, LTE is the only thing that won't work here with this phone but I don't care about that
I'll keep looking just in case, and I guess tomorrow I'll flash different ROM

If the problem is wid radio flashing a different rom won't matter ..
Have u tried flashing a factory image ?
I know flashing a new ROM wont help with radio, but I've seen that using *#*#4636#*#*, going into phone information and then Select Radio Band, gives me an error and force closes.
I've seen some threads about that, and someone saying that it was working on a CM ROM, so I was thinking of trying that in order to be able to select the radio band and see if that helps.
About the factory image, yes, I used the google images to go back to stock, and then performed the system updates.
Well I flashed Slim Rom, and was able to get into *#*#4636#*#* to change radio band. Tried them all, no change.
Played around with the preferred networks and no luck either.
I'm officially out of ideas, but I'll keep digging around to see what I can find.
Any suggestions welcome.
Also, I know that there is a known issue with the GPS signal on some Nexus 5, and there are a few videos on Youtube showing how to fix it (basically opening the back of the phone, and sticking a piece of paper under the connector).
Does anyone know if there is something similar happening with the radio? Does anyone have a photo of the phone showing which part would be the antenna?
One additional thing I noticed.
If I switch, or just take out and reinsert the micro sim, the phone asks for a reboot. After doing that, when the phone boots up, I see I have network (full bars), going into mobile operators, I can see my carrier, and I can register too. But I cant make or receive any calls or messages.
During this 10 minutes that I have this sort of fake signal, if I go into *#*#4636#*#* and phone info, I can see my carrier, but it doesn't show my phone number. Weird.
Lg nexus 5 network issue
i am facing the same issue with exus 5 .In my hometown in India,the phone simply shows "Emergency calls only" and shifts to normal working mode with full network coverage once i travel to other parts of my state (parts which probably has a better signal strength ,i dont know ).i have tried out changing the sim card and a factory data reset ..Both didnt help ..

Has anyone been able to track down the issue and get it resolved? I'm facing the same situation, and almost taking it to an authorized LG support so that they can change the motherboard.
Hey guys.. I just got my Xperia Z3 D6603 in the mail today and I can't get simultaneous voice and data working at the same time. Here is a little back story.
I owned a AT&T Note 3 up until about a month ago when I got my OnePlus One. So I removed the Sim from my Note 3 and it worked find in my OnePlus One. Since the Z3 takes a nano sim, I cut my sim card with a sim cutter. I put it into my phone and it appears everything is working fine since the Z3 has the ability to download the APN settings. However when I make a call, the 4G symbol changes to H+ and I can't use data while on a call. Does anyone know how I can fix this? Can someone with a AT&T sim try this on your Z3?

Sorry but I have heard weird things before about cut Sim Cards and one of those things is exactly as you described. So, if everything else (meaning APN settings) are fine, then your best bet is to get a new Nano Sim from AT&T.

Yea that was my next course of action. I'll head up to AT&T today and get a new sim and see if that resolves the issue. I assume yours works just fine?

One more thing, I just saw this on other thread, so take it in consideration, just in case.
<<D6603 and D6633 will support AT&T LTE. Whatever you do, do not give AT&T your updated IMEI or their system will register it as "unknown" device and you will get 3G only.>>
Direct Link here.
Thanks guys. Headed to the ATT store now to get a new sim. I will make sure they dont get the IMEI of the Z3
Update...
Just got back from the AT&T store. I got a new nano sim card and we left the IMEI settings for the Note 3. I can now do simultaneous voice and data at the same time except I still I lose the 4G symbol and it goes to H+ like it did before. I did do a speed test and it is slower. I'm getting about 13mb down on 4G and about 6mb down on H+. So i think something is still not correct. We did check the APN settings and they look fine. Any other suggestions?
This may be normal. I guess my other phones never switched symbols but it was probably happening in the background
I have a d6603 as well using a nano sim from AT&T. I get data with voice but i only get H+ and not LTE speeds. Is anyone else seeing this or is it normal
wolf0491 said:
How often are you using data while in a phone call? Sorry I just don't understand while only having access to 6Mbps is really a problem. Still a pretty decent speed IMO.
I'm using a cut sim card in mine and it seems to be working fine.
I got 48Mbps download on LTE other day...

I am not complaining and i rarely use data while on call except if i am put on hold or something. Just wanted to see if anyone else has seen this and fixed it.
I'm not complaining either since data speeds seem fine. My initial issue was that I did not know if this was normal. My Oneplus and Note 3 do not change to H+ or anything but that could be that the software is not changing it but it is still only working as H+ while on a call. It wasn't something I'm used to and wasn't normal for me. Which is why I thought there might be a configuration issue somewhere

ATT does not support voice over LTE yet, which is why the data symbol changes.
Previous phones did not show this in order to make you believe you were still on LTE.

Your post is a little old...I just came across it. So you want your phone to do Voice over LTE(VoLTE)? If yes, I know the T-Mobile branded Z3 has that option in the call settings, but the unlocked D6603 doesn't seem to have it.
I am presently in Nigeria and I got a Verizon s3 through a phone dealer. its running on android 4.4.2 stock. Calls and Data works well with mtn Nigeria sim. But each time I tried to turn on HOTSPOT, it shows 'EITHER MDN OR ICCID IS NOT VALID' and it wont turn on. Now am confused, don't know what to do and I need hotspot seriously.....Can anyone help?
To add to that..i will like to say I have already rooted the phone with trowel...and I have been able to assess the hidden menu. But I don't know what next to do.....
Even have got foxfi paid version but all to no avail.
Sorry bro... how did you access the hidden menu?

I picked up an unlocked T-mobile G5 and I'm using it for AT&T... The rep at the store applied the APN setting for ATT but I noticed after I got a new SIM installed and went home the reception and data connection started dropping in and out.
Basically, when the phone is sleeping and then I wake it starts searching for network then gets reception then get a signal for a couple mins then drops again and searches. Since it's a T-Mobile phone on an ATT network is there certain settings that I need to turn off like VoIP, WIFI calling etc? Any ideas?
Wipe out all existing APNs and start from scratch? Use the NXTGENPHONE APN. I'm using an unlocked T-Mobile H830 LG G5 on AT&T and I have no problems. My sister's Nexus 6 uses the same APN no problems either.

So I followed your steps.. I wiped all existing APNs and entered the APN setting in the link you provided and used the NXTGENPHONE APN but I couldn't get data but just had reception to make calls. So I changed the name to AT&T and the APN name to phone and I get data and reception but it still drops in and out.
I went to ATT to see what they could suggest but the only thing they offered was maybe a faulty SIM card and switched it out but it's still doing the same thing... Has anyone experienced this? Should I do a factory reset maybe? If I do that, I won't lose SIM unlock right?

I was going to suggest a factory reset as a last resort. You won't lose the sim unlock; it's permanent unlock.
Troubleshooting is the name of the game and you'll have to keep having to try potential solutions until it's fixed.
Hopefully it's not a hardware issue with the radio or you'll have to swap it out and reunlock it all over again.
are you on 10A or 10D?
10D seems to improve the radio... but if you wan root/twrp make sure you do all that on 10A first before upgrading to 10D.
also, have you tested the phone in different areas? or just at your house and immediate area? perhaps it's just an issue in specific locations? what if you drive across town or something?

Performed a factory reset and issue is still there but slightly improved but I need to test it more... Basically, when I wake the phone it searches for network (not all the time but here and there) then locks a signal..

In on 10D.. Yeah I tried it in different areas and driving when I'm art a stoplight I can see it searching for network.. I switched the SIM card and did a factory reset any other suggestions?
Is your Network mode set to GSM/WCDMA/LTE auto? If it's not area specific it might be hardware related.
How did you get the 10D update on AT&T btw?

Last thing to try is Mobile networks>Network operators>Search networks. Maybe manually choosing one might help? Enable Data Roaming?
Could be a hardware issue if not software.

Yeah, I tried that too.. Got back from Tmobile and they said that another person experienced the same issue couple weeks ago and they said that some G5s that are unlocked and used on different networks are still trying to jumping back on the tmobiles phone network hence my phone searching signals off and on...
Just wanted to give another confirmation that the LG-H830 works perfectly on AT&T (H83010D [BL,modem,system], rooted, unlocked). I gave up on Verizon and my fiancé now uses it on AT&T. She loves it!
Geez.. I got scammed. The person looks like they file a insurance claim on the phone so my ESN is blacklisted! Great! Lesson learned the hard way. Any suggestions what I can do? I saw that people are buying bad ESN phone on ebay as long as I post that it's a bad ESN.
OP, I had the exact same problem on T-Mobile after doing a temporary unlock. I took it to a T-mobile store and they tried swapping the SIM but that didn't help so they did a warranty replacement. Two days later I had a new phone and everything works again. I didn't (and won't) try to SIM unlock it again.

I did some research online on blacklist repairs but do you or can anyone give me some recommendations on it? Sucks cause even if I get it repaired I wondering if I still will have issues with the reception..
Anyone tried this site? http://www.imeifix.com/
I just tried the sim unlock as well. I'm a tmobile customer so I really didn't have a reason to do it. Just wanted to see if it would unlock.
Well it said it could not be unlocked and I, out of dumb curiosity tried the temporary unlock. It worked and said it is unlocked until August. I think roughly 30 days after I did it.
Well, later that day or the next my phone started doing the same exact thing. Signal dropping and searching. Furthermore though, I woke up to a warm phone today. Same as it gets when doing lots of app updates. I unplugged it from the charger and watched the battery drop 4% in only 15 minutes of standby (screen off, not using the phone).
I just flashed it back to stock and relocked the boot loader and will see if it fixed it. Was running rooted 10d when this happened.
I'm starting to think that sim unlock app is evil or something. I haven't put my sim card back in as of yet but will update if it starts acting up when I do.
Possible explanation?:
I noticed a T-Mobile diagnostic app try to gain root access during the weirdness which I had never seen before. Maybe the sim unlock gains a sudo root to do the unlock but on a rooted phone with a non stock root manager causes the unlock app to endlessly loop trying to gain access and thus cause a warm phone and signal dropouts? Just a hunch but would be interested to see what others think.
*** Ok so quick update, I put my tmobile sim back in and the signal is dropping in and out again. The phone worked fine before I tried the unlock. This is so uncool.
Sent from my LG-H830 using XDA-Developers mobile app
I think I may have isolated the cause. I disabled the device unlock app in app settings and rebooted. Since then I haven't noticed the signal drop out.
EDIT: Yeah, that's a big nope. I'm still experiencing the problem after a total wipe and reflashing using LGUP refurbish mode. It's still dropping in and out, sometimes three times per minute. +1 to never use device unlock app.
I'm on stock unrooted 10d btw.
Oh, and the same SIM card works just fine in my older phones.

Most likely is the one everyone recieved 3BRJ5

3BRJ5 which is supposed to be a BYOD firmware, Meaning shut phone off and can put a tmobile or any carrier simcard in it and will work for that carrier if have active simcard. As i was told about this and some have tested this.
Not sure the changes.
But I also got and installed mine this morning.
I am on cricket this OTA just killed it for me. Killed Wifi Calling, VOLTE, Message Center Settings all got disabled. You should be Ok if you are on AT&T. I also tested it with a Sprint SIM card and after the restart the bootlogo even changed to Sprint, which I guess is good if you are switching carrier. But it sucks that AT&T can't get its stuff together and fix cricket, since the cricket sim cannot provision carried features!
