Sony Xperia Z5 Compact E5823 Nougat 7.11
I used NetMonster from the Play Store (play.google.com/store/apps/details?id=cz.mroczis.netmonster) which caused my problem.
I used the option: Select radio band. I got the info: Setting the United States band mode successful OK.
Since there is no other choice and the settings have not returned, there was no GSM network service, the GSM icon is not active, when an attempt is made to make a voice connection, the icon appears with a white circle with a dash in the middle (entry prohibited).
The service mode is signaled by the radio and antenna being turned off.
The reset was, still not searching the network, neither auto nor manual.
Another SIM is also not working.
In safe (emergency) mode no.
How to bring it back?

Hi all,
Currently using Xperia Z2 with KitKat. My carrier is DST (Brunei). My carrier uses three separate operators - LTE DST, 3G DST, 2G DST, all viewable in the network operators search page.
Quite often my phone decides to drop down to 2G DST operator as the preferred, without desiring to change back up, even with switching on flight mode. If I manually search, I can see all 3 available, and if selecting either 3G or LTE, they operate smoothly for a while - 20mins or until I lock my screen.
I have noticed this with previous phones on this carrier too.
Is there anything that can be done to either lock out the 2G one, or make the phone understand that is only a last resort?
Thanks
By default the Network Mode is on LTE/WCDMA/GSM (Auto) mode but when I switch on mobile data, nothing shows up, no data connection. And sometimes even no voice service, it shows "emergency calls only".
But when I switch to GSM only mode, EDGE connection shows up (which is normal), Internet goes normal but very slow with EDGE connection (Sometime GPRS).
I tried to swap SIM with my friend, and their SIM works fine with my phone under LTE/WCDMA/GSM (Auto) mode and I do get HSPA and HSPA+ Signal. (Network provider setting changed to their network provider)
I contact my network provider and they said my SIM has no problem, they did insert my SIM into their device and found no problem with my SIM on their device, they get HSPA+ signal with my SIM. And they ask me to take my phone to check for hardware failure.
I checked the APNs and network provider setting, reset back to Stock ROM and clean install my ROM several times, still have no luck
My subscription do have HSPA connection and has been using it for months at the same location, but now it just stay at EDGE and GPRS only.
Is that really a hardware problem? Or could it be SIM problem?

I have exactly the same problem! Same ROM as well. Update to various CM13 releases, factory reset to stock kernel and rom but nothing helps.
Hi,
I bought this phone Lg G4 h810, it shows AT&T logo whenever i boot it and the problem is despite of network mode on lte/wcdma/gsm/auto it always runs on2G internet speed and shows E sign.
I am from india and many service providers are still not offering4G internet service. But this phone doesn't even runs on wcdma. My previous phone lenovo was nicely running on wcdma and always showed the sign H.
My cellular operator is idea cellular and i had a word with them, they sent me settings and all and help me input the settings manually too, but nothing worked.
I checked even the frequencies, idea cellular is offering UMTS B1(2100) and UMTS B8(900 gsm). I checked this on LG website and these bands are compatible with the phone i bought, but still i can't get anything more than2G. Why so?
Plus there is one more problem, when i switched it on for the first time it showed update available And when i tried to update, it showed error and now always there's an icon on top left corner of phone saying couldn't install system update. I tried restarting and updating the device many times, but it's still the same.
Any help is much appreciated.
Thanks in advance.
Have you put your Company APN?
Yes i did, the company executive even helped me to manually save the settings to run the internet in a 3G mode. But all efforts in vain.
Did you solve the issue?
Anything new? I have the same problem.
I have this problem too
Try hidden menu with *#546368#*810# and under Field Test menu / Modem settings if there is VoLTE on/off chose VoLTE and restart. I have done that and my phone starts working with 4G. Don't forget to set up good APN if it's not automatically set by network provider.

Hi
Under VoLTE there is another entry named "Session" and in there
RPR(on/off) switch
I enabled it and restarts but it is again on 2g
Anyone further on this issue??
I have this problem too
I was flash the stock firmware,custom firmware customizing the build.prop,changed the settings in the engineering menu *#546368#*810# disconnected volte,changed LTE bands forcibly. Nothing helps,dont work 3G LTE - 2G only(. I realized that I need to re-flash (change) the original QCN file for H810 and re-register IMEI , but I can not find QCN it freely available.
Hello there, i had the same issue. The fix that worked for me was searching for network manuallly and reconnecting again to my carriers LTE network. Worked as a charm. The issue maybe was a brutal handover as I had been travelli g from a city to another one 200 km away. So somehow I had been disconnected from the LTE network and left stranded in the 2g one. Try it it should work
Hey all, thanks in advance for any advice offered.
For some reason my Galaxy S8+ has a greyed out GSM signal bar with an 'x' next to it. As far as I remember the only thing I did was put it to charge overnight. I've tried removing the SIM, still grey, inserting another carrier's SIM (known to be working), still grey, my original SIM also works fine in another phone. Everything else not related to cell service works fine (wifi, bluetooth etc.). I can see the IMEI number in settings as usual.
I've tried resetting the network settings, factory resetting the phone, I've even reloaded the ROM via Odin. No joy.
The phone is pretty much stock, except for the fact that I changed the carrier software from AT&T to Verizon in order to use a particular LTE band. Since I did that, the phone worked fine for several months.
I've only noticed two things odd thus far. After reloading the ROM and downloading a few updates, a game (Empire) appeared from nowhere installed in my app drawer. Also, the Airplane mode icon in the notification shade is light blue, similar to when it's transitioning from off to on. Airplane mode seems to work though, because I can toggle it, and the wifi reacts as such.
I can't search network operators manually (says: Error while searching for networks), changing the network mode does nothing, and none of the secret dialing codes work either. They all say "Mobile network not available". With a SIM inserted, my SIM status menu says, Network: unknown, Signal strength: -113dBm 0 asu, Service state: Radio off.
Sorry if I'm long-winded, but I'd appreciate any assistance at all. Thanks again for taking the time to read.
I had the same issue and I replaced the daughterboard and antennas
I'm living in a border region where my phone frequently switches to the abroad network in cases where the signal of my domestic operator fades. So I manually select my domestic network in the settings. However, my manual selection doesn't stick and the OP7 returns to automatic network selection once it loses signal of my domestic operator. This results in frequent connections with the abroad network and excruciating costs.
Solutions I've tried:
- manual switching networks: as described above, manual network selection doesn't stick
- 3rd party apps: I found an app which warns me when I connect to an abroad network which isn't very helpful since by the time I get the warning, the connection has already been established and the costs have incurred
Does anyone have a similar problem and possibly a working solution?
turn off roaming?
I'm using an abroad (German) sim so turning off roaming is is not an option. Just wondering if it's a bug in oxygenos that my OP7 keeps ignoring my manual network settings, which would be a perfect solution if it just worked.
Same problem here OP7. Roaming in Poland atm and if set to automatic no data. If I select a provider manually, it works less than 4 minutes and then switches back and data goes away.
Same story on 8T, this is not acceptable at all!
I was so happy with this phone, but this will be my last OnePlus phone.
