[Q]Mobile network problem during searching carrier.

Hello i didn't find anywhere similar problem. I have N5, rooted and with stock rom & kernel, i have a problem with mobile network. In my country there is a network "Play" and it is using own transmitters or from other networks and it is working as roaming network. When i want to find other compatible carriers from menu (manual mode) searching took so much time, more than few minutes. There is a sollution for this? Or fix?
Same situation when i switch from 2G to LTE mode - same results.
Best regards g1b50n

I don't think you can just switch carriers from the network menu. You need their sim card to use them. "Roaming" is usually just automatic, if you have it enabled in setting.
You don't click on different carriers to roam. At least I've never heard of that. To use a carrier, you need their sim and APN settings.
Call your carrier and ask about it. They should know exactly how it should work.

In my country carrier "Play" allow to use other networks. I mean a problem when i want to find other carriers

Then took so much time to find other networks.
I can connect with all of them (only orange not working cause was for testing)
Just want to know why looking for other networks take so much time.

Sorry, never heard of it....so can't guess why.
It probably falls under the" it is what it is" category.

No service - Emergency Calls only - Nexus 5 D821 in France

Hi,
Hi
A friend of mine have lost signal on his nexus 5 since Thursday 6 October 2016.
I have noticed the phone took a security update of the 05 October.
The sim is recognized. I tried with my own sim too.
The apn settings is good according to the provider website.
The imei is present.
When i search network operator, he take one minute at least and find my operator but afet that he i pick him i have the message "can't connect to this network riht now. Try again later"
I tried to flash a precedent stock version but no signal.
I tried to flash the modem too (downgrade) and no change
My last option is i have noticed that when i tap *#*#4636#*#* on the phone, i can select radio band and after that i see "usa band" but i'm in france.
In France we use GSM 900 and also LTE (4G)
I tried to flash the cyanogen last version and i see a change but still no service, no signal.
The change is i can see usa band + japan band now but no Europe band (if that exist).
It's look like those settings are decided by the rom or by the kernel (but not the modem firmware)
If someone in France or Europe can tell me if he has Europe band in select radio band, that would help me to understand better

Try this method:

If it fails, also try this one:

Thanks.
I just tried both method.
Though now i have access to euro band, the phone still stay in no service... very weird.
I suppose it's an hardware trouble finally.
Thanks anyway, i give up ^^

My D820 has never picked up anything above 2G

Hello everyone.
In november of 2016 my aunt bought this Nexus 5 (D820) from Amazon in USA and brought it here, it was brand new and factory unlocked. When I first got it I didn't flash anything on it for a few months, which means I used the factory 4.4 KitKat, and I noticed that it never picked up anything above 2G/EDGE (the small E icon). Right now I'm running Nougat and I've tested it with 3 different simcards throughout these two years and it simply never goes over 2G, I have never seen this phone with an H or H+ or LTE icon. It's either 2G or it simply drops signal.
Here's what I've tried so far:
Using the stock system
Flashing ALL the radios I found, through adb and through flashable zips
Tearing it apart to see the two antenna cables on both sides, they're there and well seated
Every single combination of Cellular Networks > 2g/3g/LTE, Roaming, no result.
I've tried different APNs, still no result
All 3 SIM cards worked with 3g right away on my previous phone, an S2
I honestly have no idea what to try next. Anybody could help?

Maybe, it's because your networks are using frequencies, which are not supported by the North America (D820) model.
See https://www.androidcentral.com/nexus-5-models-whats-different-between-two

D820 is for North America, D821 is for other countries.

The only thing that shouldn't work outside NA is 4G, my actual mobile carrier is Movistar, and it should work right away so..

LG V50 Verizon Model - Unable to Make Calls

Hello all,
I seem to have an issue with the phone whereas phone calls are not working on the phone (call \receive). I thought it was an issue with the phone not unlocked but it is. I confirmed by looking at the following:
- Phone says Tmobile at the bottom of the screen
- when searching for networks, mentions all - Tmobile, ATT, Verizon, MetroPCS
- manually selected Tmobile as well as Auto Select Network
- texts work on the Tmobile Sim
- Chrome browser loads pages (data not set to roaming)
- factory reset phone and the issue persists
- inserted known working Verizon Sim to test phone ability to make calls \ receive and works ( able to dial out and ring)
- browsed around the Phone app => turned off Assisted Dialing, Video calling
At the moment, I am trying to get the KDZ to possibly flash the firmware to see if the Radios flashover.
Any thoughts?

Nevermind.
I was able to confirm that it is unlocked and able to work with TMobile....sorta. Calls come in when the phone in certain areas where it can switch to a 2G network and switch back to LTE once done.
I also noticed that the 5G UWS icon appeared in some areas. Speed test doesn't show anything 5G like (20mb down, 17 up).
I would hope that cross flash comes out soon. Lol

Hey hi how you unlock your v50 from Verizon

Samsung Galaxy S10e SM-G970N LTE Lock

Hi, i 'm pretty new to android (just made the jump from an iphone)
I got a Samsung Galaxy S10e (korean KTC version), and i noticed that the signal is always on 3G even though my phone supports both lte bands that are used by my carrier (B3 1800 and B20 800)
Digging into setting there is no way to chose preferred network mode but i notice there is a setting called service provider that has an giga lte option but when go to enable it it just says that "giga lte cannot be used while a non-kt USIM is inserted, insert a kt USIM and try again"
So i though is it possible to unlock the lte functionnality by flashing a rom through odin for the korean vertion of the phone but with no carrier lock?
I found this stock korean S10e rom with no carrier lock (screenshot bellow)
Did anyone do it before ?
Does it work?
They have the same model number but not the same CSC file, would it be possible that this works ?

If the phone carrier locked then flashing a rom will not unlock it. You would need a Sim unlock code from the carrier to use a different Sim card. You may me able to carrier unlock it from various websites that an unlock code for purchase. Try a Google search for Sim unlock code. Good luck.
