Hello,
I'm having trouble using my phone in roaming. My home mobile provider is Vip net., in Croatia. I'm currently in England, and my phone is currently connected to Vodafone network, which a partner of Vip.
I'm unable to get mobile data connection unless I'm connected to Vodafone 4G network. When I do a manual scan of networks, I can see (most of the time) three instances of each network (4G/WCDMA/GSM). Whenever my phone decides to switch from 4G to WCDMA or GSM, I lose the mobile connection.
APN is of course set correctly since otherwise I wouldn't be able to connect to the network on 4G (I've even had my provider send me the APN configuration message to make sure that's correct - I also tried various modifications to settings of the same).
I've talked with my providers technical support and they haven't been able to provide me with a solution, so I'm wondering if anyone here might have a clue about what is happening?
I've tried doing some basic diagnostic with adb, but haven't been able to gather much from modem logs, which I've attached here, and I would be grateful if anyone would take a look.
Here is the log, please note that it starts with me turning on mobile data and ends with me turning it off:

The phone in question is LG G5, Android 7.0 Nougat, Stock rom. (I had the same issue on 6.0)
Thanks guys!

I have Samsung Galaxy S 4G with T-Mobile in San Francisco.
Whenever I go to an area without T-Mobile signal, the phone connects to AT&T. I called T-Mobile and they said that's because T-Mobile has roaming agreement with AT&T so my phone would connect.
The problem is, when my phone connects to AT&T, I can't make any calls. It says the phone's not registered. T-mobile says that's because I'm in an area that has T-Mobile coverage.
You'd think that the phone would be smart enough to figure out that only emergency calls can be made (which is what BlackBerry does and shows SOS sign). The real problem for me is that, I have WiFi calling enabled with cellular preference, and when I'm in the basement of my office building where there is no T-Mobile signal (but there is WiFi signal), my phone thinks it has cellular signal so it doesn't activate WiFi calling, yet no phone calls are coming in b/c it's not registered to AT&T's cellular network.
Is there a way for me to force my phone to only connect to T-Mobile? I know there isn't on the regular settings menu, but perhaps experts could tell me how to do so using those star-sharp keys listed here (http://forum.xda-developers.com/showthread.php?t=842134)?
Thank you!
Set wifi preferred instead of cellular.

Unfortunately, that doesn't work for me because I move around a lot, and Android WiFi calling feature doesn't have handover.
There's got to be a way to prevent this phone from connecting to AT&T at a low level somehow, no?
How do I do that? Have checked the manual but can't find location where explains how to select wi-fi preferred instead of cellular. Your kind advise will be appreciated
Open WiFi Calling and select settings. You'll see Preference. Select Cellular Preferred.
I think in setting then wireless and network, then mobile networks then network operators click the default settings.... select manual and wait for the carrier to pop up.
Will this solve your problem?

yep manual is exactly what OP should do.
if the settings for network operators are set to manual then u select the network u want and it sticks unless u manually select a different network provider. u are in select automatically mode so the phone can switch all on its own. this should solve your problem as other people have already mentioned
I have tried this many times and works as long you don't turn the phone off. After I forced the phone to manually select T-Mobile I checked many times the default setting and it remained in manual until the phone was turned off. When I switched it back on it was again in automatic mode and switching to ATT when signal is low.
Is there a way to prevent this? If not, well , first thing when phone is on in the morning is to check default setting.
5/24 I finally gave up and sold the phone. Samsung says they have not received any claims regarding this issue eventhough you see it frequently in the forums. I returned back to my HTC HD2 and will wait for the G2.
Hi everyone,
I bought a Samsung Galaxy S GT-I9000 (16gb) in Singapore and was using it fine on Singtel's network (signed a contract with them). Now I have moved back to Canada and brought my phone with me assuming that all would be ok to use it with the network here. However I'm having big problems with this one network I just signed up with (Virgin Mobile).
85% of the time I cannot connect to it: voice calls and SMSing won't work nor will the data work on it, the only thing it says is "Emergency calls only". Then at other times everything will seem to connect and work fine - I can make calls and use data.
Virgin Mobile will not support me much because they're thinking it's the phone's problem, if I use the phone they gave me (a lower-end model) it works fine.
Here are some details of my phone:
Firmware version
2 2
Baseband version
I9000DXJPA
Kernel version
2 6 32 9
root (at) SE-S604 #1
Build number
FROYO DXJPA
If I check out the status, it usually says this:
Network
Unknown (switches to VIRGIN when it does work)
Mobile network type
UMTS (switches between that and HSDPA and GPRS)
Service state
Out of service
Mobile network state
Disconnected (switches to connected when working, and even when it's not working sometimes)
I have Network mode set to auto mode (GSM/WCDMA). I've tried to switch it to GSM only but that didn't seem to change anything.
I'm wondering if there's some kind of configuration settings I still need to do with the phone? I'm also wondering if it is the network I'm with right now? Virgin Mobile isn't one of the bigger telcom companies here and I'm thinking that if I switch to one of the bigger telcoms, will it work better?
Something else to add - before I signed up with Virgin I was using my phone with a pre-paid service (called Chatr) for voice only and it was working fine.
I'm sure this phone can support the GSM frequencies here.. can't it?
I also still have the Singtel customizations on the phone. Will it help if I remove it?
Any help would be greatly appreciated!
Thanks a lot!

sorry, wrong category..
Hello,
I have a Nexus 5 phone that came with Kitkat a few months back. The phone worked without issues until I decided to update to Lollipop 5.0 (OTA update) at the end of November. Initially the phone started to have troubles to detect the network at certain times - typically "playing" with the settings "Preferred network type" by changing from 4G to 2G, restarting, letting the phone detect the network on 2G mode and change back to 3G or 4G would fix the problem. The issue became more and more frequent until a point where i can not change the "Preferred network type" from 4G to any other type (as if it is "glued" on that setting). At this point my phone does not recognize at all the cellular network but It does seem to recognize the SIM card since i need to enter the 4 digit code to unlock SIM and it displays the network name, just no service.
I've researched the internet and I've tried several things but nothing seems to fix it such as restart mobile, change to airplane mode and back, take out and re-insert SIM card, request new SIM card from operator. The APN settings seem to be OK.
I've noticed that a new 5.1 version just came out and although I was not fully familiar with the process i decided to give it a try (after reading several instructions) and update manually (using factory images posted) and see if that would fix it. The phone is now with version 5.1 and still can't recognize the cellular network - no service. Everything else works fine, including Wi-Fi.
Has anyone experienced such issue after OTA update? The only odd thing I can think of is that I did the initial OTA update to 5.0 in US while i was on travel from Europe, but I can't say if this would in some way contribute to the issue. The mobile is D821 model.
Since I was stuck and mobile is within warranty period, I have sent it to service repair. I would be interested to know ideas of what could be the issue cause.
Sorry for long message, any help would be very much appreciated.

Hi, I recently bought a LG g3 smarthphone and I found out that it's an AT&T version phone, but thankfully it's unlocked. My problem is, that it doesn't get any mobile network. In the setting it says that the Mobile network type this device can use is HSPA, my local carriers can only provide LTE, GSM and WCDMA rat types, I don't know if it's the case. I've tried to solve this on my own, but without luck. The solutions with 3845#*850# or similar codes just woun't work, when I choose any RAT it says: "succsess", but it doesn't change a thing and when I choose "LTE only mode", the phone blocks my mobile connection and says: "Restricted access changed: Data service is blocked" .
I really need any help, because I cannot see myself using a mobile phone without mobile internet. I tried to use 2G, 3G and 4G networks, but none work, nothing appears. Also I tried to fix this problem by flashing a Cloudy ROM wich is lollipop 5.0 and it didn't solve my internet problem. BTW, my location is Estonia.
I really need your help guys, I'm desperate as hell, this is my last option, because I didn't find any other solutions on my own.
Counting on you :3

I think your a little confused about your network. HSPA IS WCDMA/GSM. You want to just slept gsm/WCDMA/LTE

Flashing a ROM is not the solution. AT&T version of the LG G3 covers a limited radio frequency spectrum. It could be that the phone does not cover the frequency of your carrier. Another issue may be with the carrier themselves blocking the IMEI (I know some carriers require registering the IMEI on their network). Of course you must also make sure the carrier has data services available to you.
I kinda have the same problem....
No service.
I've tried everything to no avail.
Help gor a fix.
no matter what ROM i use, no matter in what manner I flash said ROM, my XT1548 simply will NOT connect to mobile data . the problem seems to be that a cellular signal needs to be established in order to "activate" the SIM. (I guess this isnt a problem with contract phones). however, I cannot get a cellular signal at all. Ive tried airplane toggle, cellular toggle APN, you name it. I just want a working ROM that lets me use my US Cellular registration . I will post any logs or whatever I need to help. but can anyone help out here? it seems that with VIRGIN the problem was solved within CM13 (virgin "data anywhere" or whatever it was). but how can the US Cellular version be helped?
