I am new to the forums, so please go easy on me.
A quick back story....where I live, I have to use a Verizon Network Extender to make and receive calls & texts from home. VZW's Extender only works with 3G. Since the upgrade to 4.1.1, the mobile network menu only has choices of Global, LTE/CDMA and GSM.
Until yesterday, I have been using an app called Phone Info to manually set my mobile network to CDMA Auto (PRL) when I got home and it worked perfectly. Since the update, the Phone Info app no longer works and I cannot find an app that will allow me the same access to set my mobile network. I receive just enough of a 4G signal where I live that my phone will not auto switch to 3G. So now I have an expensive paperweight at home.
Can anyone point me to an app or tweak that could help me with this problem?
Thanks in advance.
I really need help with my device, I searched all over XDA and no-one seems to have the same issue as me.
Here is some information:
1) Nexus 6P (H1511)
2) 6.0.1 Absolute stock, no rom, no root, no custom recovery. Build number MMB29P.
Recently got a new Nexus 6P and imported to Russia. All of the major bands here are supported. And the phone worked excellent for a few weeks, but then it lost all 3G or GSM connectivity. Just randomly,didn't do anything with it, the only thing I did is move to another city but than I got back, the issue didn't resolve. LTE works perfectly but can't call or receive calls, can receive sms though. Reseting network settings and factory reset changed nothing. Tried manualy set network to WCDMA or GSM with *#*#4636#*#* command, the moment I switch to anything besides LTE the connection is lost. Contacted the provider, no problem on their side, my SIM works good in other phones, my phone with other SIMs - no.
I don't think it is a hardware issue because a few times I managed to get everything working after an hour of switching networks and bands with no particular order in the *#*#4636#*#* testing mode.
After a while I figured that if I set phone to "GSM only" on USA bands in testing mode, but at the same time set it to "LTE prefered" in the normal network settings menu. I am able to set phone to Band mode 7 and set the network back to 2G in network settings keeping it on " GSM only" the whole time and only after this compicated algorithm and after a reboot 2G and 3G starts working. But any reboot after that revertes everything back to only LTE stage. Also if I get everything working but than reset network settings everything stops working again.
I have no idea what caused such an issue, I really hope someone can help.
Sorry couldn't post screenshots because of the "10 posts rule".
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!
About a month or so ago, I went on vacation to Asia with my S7. I had it on airplane mode pretty much the whole trip but turned wifi on when available.
Since coming back, my S7 stopped being able to get on to the LTE network. It stays at 4G, which is HSPA speeds on my network. There is discussion about 4G and LTE being the same, but I'm experiencing much slower speeds...5-6Mbps compared to 25-30 when my phone showed LTE.
It's definitely my phone as I put my SIM in another S7 of the same network, and that phone went to LTE. Their SIM in my phone stayed at 4G.
I've tried various APN settings, made sure GSM/HSPA/LTE was selected, reset the network settings, tried some apps that said it would force LTE...but nothing is working.
When the app does force LTE it says I am in Roaming mode. I checked the CSC and it does show my correct network carrier code.
What can I do here?
Have you manually selected and registered with your carrier's network from the network settings?
Settings > Connections > Mobile Networks > Network Operators > Search Networks
Cleared cache from recovery?
Called your carrier?
Factory reset the phone
Switched carriers from TMobile to Xfinity mobile and now I have no data. I get phone service but unable to acres internet. Is there a way to trouble shoot this?
Need to make sure the network mode is set correctly, that Mobile Data is enabled, and have the correct APN set up
