[Q]Mobile network problem during searching carrier. - Nexus 5 Q&A, Help & Troubleshooting

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.

APNdroid has no function on rooted R2BA024

regardless of apndroid status, 3G traffic is transmitted.
does anybody has the same problem?
using rooted R2BA024 with apndroid 2.1.3
This is no firmware issue this is O2 Germany Issue
O2 Germany accepts faulty APN and let you go online anytime! So if you don't want internet traffic simply disable MMS&INTERNET or give o2 a call and let them disable it for you!
Regards
Bin4ry
but why did it worked before the update?
updated o2 anything, too?
SMODA Widget disables internet like the button in preferences. it also prevents mms beeing received.

I dont really think that it worked like it should. maybe it worked, but you was still connected to internet sometimes (we speak of 3G! on 2G it will work as i know, but not sure!)
I had a discussion with o2 some days ago because of internet costs about 90€ just for 7 hours my GF has forgotten to disable internetconnection in settings until flatrate was activated.
O2 says that they want to be userfriendly, so they enabled access for ALL APN-SETTINGS even if they are not right!
And now what? We have to pay 90€ and i immediatly quit the new contract again. Bad for o2
I just wanted to warn you to have an eye on that

SMODA Widget is not as goog as i thought. I reads one the page that this app is using undocumented internal functions... some other apps know these functions and are using them too, therefore, SMODA cannot lock internet traffic securely!

by using *#2263#
i found it dose not work on WCDM where i am
even if it was on auto
when change to GSM it worked.
any clue for this issue?>
What network are you trying to use?
Captivate has the following bands:
GSM/EDGE 850/900/1800/1900
UMTS/HSPA (WCDMA) 850/1900/2100
Note the absence of WCDMA 1700 for TMobile USA.
am on GSM 900/1800
WCDM 2100
when am on 2100. i can recive call
but canot make calls
any help?
why i can recive but canot make call on WCDM only
any one????????
Excessive bumping is highly unnecessary. If we knew and could substantiate an answer, we'd have told it to you already.
The only advice I can give is for you to force WCDMA2100 only via service mode through *#(*#)2263#(*#*). The additions to that code in parentheses is for CM7.
This is a total guess; I really don't know how to help you. Try different modems if this fails? Since it looks as if you have a Captivate ROM, make sure you only use an i897 modem, otherwise you'll break Bluetooth.
T-mobile and att network not compatable for 3g data. You can make calls but you will only get EDGE speed data.

Phone drops signal on wake up/unlock

Almost every time I wake up my phone it completely loses radio signal and I cant get or receive calls. Happens on 3 different roms and radios. It started after I changed my cellular carrier so it may be related. It may also happen why the phone sleep but doesn't seem to anymore since the last flash and modem: sky-ics 4.2F with uclf5 modem, also mohans kernel 1.5.
I did tons of searching at the closest thing I found is a nexus issue which is related to the kernel smart reflex function which with my limited knowledge couldn't find in our kernel files so I could use a script to turn it off.
And ideas?
Update: I tried using my brothers sim card in my phone(he has a different carrier) and mine and his phone, his phone is a dumb phone. On the skyrocket there were no signal loss during the few hours I tested it. On his phone I couldn't see signal loss as well tho its harder with no log.
I'm guessing the skyrocket and the carrier are conflicting in the software/maybe hardware level. I don't have enough knowledge to know how its possible tho.
It never happened on my old carrier, and I'll be happy if anyone got a clue how to help me find the issue.
Oh also for a while after I returned my sim to the skyrocket the issue was gone until I restarted it.
Here's a picture that will show the wake+screen on and signal loss correlation:

How to change band radio

Hi everyone,
my used xperia xz have signal/network issue: when 4G is on and i receive a call the signal is so low that i have to move around or turn off lte to have a better experience; data signal is so low and laggy, sometime havent signal indoor etc... I bought a used device, originally come with UK firmware and this specs:
Android 8.0
Phone Software Version: 1302-9157_41.3.A.2.171
Global-LTE3A
Generic-41.3.a.2.171
S1 Boot version: 1299-4832 S1_BOOT_MSM8996_LA2.0_O_204
BASEBAND: 8996-8996.gwn.prodQ-00070-40
Customization version: 1305-7307R8E
After a guide of Kuarinfou to flash a firmware i flashed an italian firmware (cause i live in italy and i thinked to could solve it flashing an italian fw) but the signal/network issues are still there. I checked the service menu and I notice that:
- in the network preference's list there isnt the option "LTE/UMTS/GSM" but only LTE/UMTS or LTE/CDMA or LTE only or CDMA only and others combinations
- in the "select band radio" (the first option after clicking the three dots at the top) there are only 3 option: Automatic - America - Japan. NOT Europe!!!!
So I suppose this could be the reason of the issue. I suppose there is a network "limitation" about frequencies.
My questions are:
1) Could be that the reason of the issue?
2) Is there a way to change the band radio?
3) Is there a way to set on europe band and disable US or other bands?
I have read the post about how to modify lte carrier aggregation, could be the solution?
I will attach a screenshot for more info.
Hope in your experience and kindness.
Anyway, thanks you for the attention

Question My Phone Had a Setting Then Dissapeared After I Tapped It.

Hey guys so I was going through my settings under more connections I saw a category with only one option called.
Samsung Network Connection then the setting was called "Network Unlock" I tapped it and nothing happened. Then I tapped it again and my phone refreshed real fast and the setting now is gone.
I went to Network operators to see if I could switch networks just wondering if that setting allowed me to or not only to find out no it didn't. So has anybody seen this before and maybe know what it does?
Network Unlock means your device can be used with any service.
if it disappeared then you have Network Unlocked your device.

your looking at Network Operators, that is just to select what mobile company tower your connected to, most of the time that is set to automatic.
Network unlocked means you can put any company SIM card in your phone and it will work on that company network, Only if you have service with that other company.
look at attached images, then let me know what your phone says
Yes that was the setting that was there I got up to 3 then when I tapped on it my phone screen refreshed and now that option is gone & I never got to see picture 4.
I attached a picture to show that setting is gone now.
Do you know if it's possible how to make that option reappear?
