d820 is for the north american market, but it should still connect to phone calls, just not lte http://www.phonearena.com/news/Differences-between-the-two-Nexus-5-models-D820-and-D821_id48985

So sorry I meant D821

have you tried to use a different sim card? someone elses sim card..

My nexus Sim is Vodafone and I have a tablet that supports calling with Etisalate Sim, I switched the Sims and the Vodafone one works perfectly on the tablet but the Etisalate don't work on the mobile and when I returned them back the Vodafone don't work again and the Etisalate works again so the problem is with the phone

I tried re flashing Paranoid Android but the same problem

Try flashing stock. If it's the same, it's hardware. Sim card, device or something. Or its carrier related issue.

Sounds like the radio is set to LTE only mode.
Dial *#*#4636#*#* and check your network configuration

S6 Edge At&t unlocked No update and LTE signal

Sir I purchased a new unlocked S6 Edge ( 925A) at&t device from abroad to use in india.
The guy told it's fully unlocked and it support any sim card. Buy when I checked with Indian Sims I am getting only 2g signals .. I am not getting 3G and 4g signals..
When I checked for network selection mode settings it's missing in the settings.
No software OTA update is available. . I think it's also disabled.. when I checked the device status it is in "custom"..
So if I flash a stock ROM with Odin will it lock again ?
Do I need to unlock it again.. ??

First check the model from bootloader, if its actually a att variant then you can flash a stock rom too make it work as normal, but if its some other variant then get back to this thread again.

Its surely an at&t Variant of Samsung Galaxy S6 EDGE.. its model number is 925A.. which is only available for ATT..
Its baseband version is G925AUCU1AOCE
I purchased this phone as fully unlocked from UAE but in india when i start to use it i came to know that its not taking 3G and 4G signals .. but 2g Signal and Data services are working fine..
I got the phone in rooted condition without any Boot animation of At&t. Since its rooted i am not getting any official updates.
I am also facing many software bugs.. from different apps..
So really want to flash the phone with a new stock rom for using it..
I have some doubts about it please clear it..
1) if i flash it with an official att stock rom will it lock again for att network ?
2) can i remove the att boot animation after flashing with stock rom ?

Providers in India use bands 3, 40, and 41 for LTE. The AT&T S6 Edge is only compatible with band 3.
I doubt you'd be able to flash a different ROM, and even if you could, you still wouldn't have compatibility with bands 40 or 41.

Firstly Thanks for your reply.. i know that S6 Edge at&t only support Band 3 LTE cuz it's a FDD LTE supported device.. in my country here providers are using both TDD & FDD LTE bands for LTE..
In my region "Kerala" at presently all the providers are using Band 3 which is compatible will my phone. But i am not receiving any LTE and 3G signals..
My friends have different unlocked phones from T-Mobile they are not facing any problem..
I am still doubt the flashing ROM.. i am going to flash the stock rom for at&t.. it's the only official rom available for my device.

It could be an APN issue. Make sure the settings are the same as your friends are using. Beyond that, I have no idea.

Nothing Wrong with the APN.. cuz i am using 2G data without any problems.
We have same APN for all 2G ,3G & 4G..
I think its the problem with my software..
I can't switch between LTE/WCDMA/2G because that network mode selection option is disabled or not available..
I am compelled to flash a new Rom..
I don't have any other options.
I own a good phone but i can't use it . Really sad about it..

for sure people here can help you more on this

If your doing using lg flash tool or Referbish flash in LGUP and performed a factory rest from recovery and still have an issue it most definitely sounds like a hardware issue.
Have you tried connecting to a open wifi network or a different wifi network??

I tried 8 wifi network, everytime phone says wifi saved. If it is about hardware, how can i fix this? My phone doesnt have warranty. I buyed this phone in usa and i guess this phone doesnt have a repair service in turkey.
And my phone's imei number is clone, can problem be about this?

If it's hardware you can't unless you take it somewhere to be repaired. You cannot fix hardware without taking apart the device and or replacing a part. If your imei is not original that has nothing to do with WiFi only cellular.

It's a hardware problem. Only fix is usually a board replacement. It's a common problem

Its not a hardware problem because i am facing same problem but my hardware is correct and i started to face this problem after marshmallow update

Problem Solved
I have solved my problem.
This problem arrises due to installing custom rom and restoring qcn and it could not be solved by restoring back to stock etc.
Simple solution to that problem is
First you need to install any Marshmallow firmware custom rom fulmics etc.
Then go to hidden menu
1- on dial pad : *#546368#*850# (850 is for D850 and write for your model )
2- find and click SCV Menu it should be 3rd one
3-click on CRCWIZARD Test
4-click the tab Auto MID
5- uncheck IMEI in MID settings
6- click generate to generate your new MAC's
7- click MID write
8-Click Refresh to be sure that you changed MAC adress
9-Rebbot phone to take effect!
After reboot you will be able to connect any wifi without having wifi saved problem or connection failure

Known Issue with no service (signal)

Hi i have a nexus 5 (d 821) and i'm trying to get it work again. It has no signal with a valid sim card. i am in europe.
I tried cyanogenmod ( it shows usa, japan automatic ) but no signal.
i tried lineage the same thing.
I restore it in 6.0.1 google img ( it shows only usa band ) but no signal.
i restore in 4.4 ( it shows only usa band)but no signal.
Is this problem software or hardware?? is there any rom that can make my phone work again?
I searched through the forum and cannot find any clear solution for nexus 5
thank u

Was the phone ever dropped or dismantled and put back together?
It finds no networks at all?
Sim card works in another phone?
Tried other sim cards in the Nexus?

If this is a 2nd hand phone device and a problem with other sim cards too, I'd check if the IMEI has been blacklisted by a previous owner?

it has some falls , but i dont think this is the problem.
at *#4636 menu it shows only usa band (original nexus rom) and auto us japan band in lineage rom.
I think that the problem is in software with the radio img, or else with antenna or motherboad as hardware.
i need the opinion of an expert to deal the software part,
the sim cards works on other phones...
