I screwed up my phone. I'm on Consumer Cellular on their T-Mobile version. If I go to *#*#4636#*#*- I get to the phone info page. In the middle of that page I fat-fingered the dropdown for "Set Preferred Network Type:" and I don't know what it should be. If I put "LTE Only" I have data and no voice service.
I'm running Lineage 8.1 so in the settings for the phone I have lots of options under "Network & Internet", "Mobile Network", "Advanced", "preferred network type" and this has other options.
I've tried all kinds of combinations and I either have LTE and can't make or receive calls, or I change it to something different and can make and receive calls but no data. When I make a call and hang up I don't have data anymore. I'm not sure what combination I should be using so I have data and also get calls.
Anyone running Lineage 8.1 on T-mobile? If so, what settings work for you?
Thanks in advance,

I was messing around with the settings and I went into settings, wireless & network settings, mobile networks, network operators, and I registered with a network (Bell) and now I can't get any service. The "Use only 2G networks" checkbox is always checked and when I dial *#*#4636#*#*, it shows I'm using GSM preferred networking.
What can I do?
My carrier is Bell Canada btw.
Back in the testing app, change GSM Preferred to WCDMA Preferred or GSM Auto (PRL)
Tried that, it changes itself back and i still can't connect.
Should note that when I try to register on Bell, it just says "your sim card does not allow you to register on this network"
As you may or may not know, Bell does not have a 2G network. So if "Use only 2G networks" is checked, you wont get any service. Are you saying that you cannot uncheck this? I think it's usually best to let the phone select which network to use automatically instead of telling it to specifically use Bell.
If none of this is working, then it might just be an issue with Bells network that will resolve itself eventually.

Yeah, I'm aware Bell has no 2G network, but when I go to uncheck the box, it'll recheck itself in a few seconds.
Strange... all I can guess is that Bell is having network issues. If you can call them from a different phone they might be able to confirm that. You couldn't have broken your phone by playing around with those settings.

Yeah you were right, there was something wrong with bell's network. It's all good now.

This is really annoying me. Whenever the cell signal goes to nothing or has no connection to T-mobile (say when I walk into a dead zone), the phone goes BEEP BEEP, and the screen will have a red triangle with a + indicating "emergency calls only". I DON'T CARE!!! I just want this to stop, and I can't find the option anywhere.
i believe youll find your solution in settings > more > mobile network> roaming >roaming notification

When I go to Settings/More/Mobile network settings there is no Roaming option. I see Data Enabled, Data roaming, Access Point Names, Network Operators, Select Network. Nothing about notifications.
I have the Bell model, fwiw.
Now that you fine folks got s-off working on version 4.4.2 for the HTC One, I was able to put Cyanogenmod on it today. Things seem to work okay, except for the one glaring issue: I can't use the phone to make or get calls. If I look at Settings->About Phone->Status, I get this:
Network - Verizon Wireless
Mobile network type - LTE
Service state - Voiceut of Service / Data: In Service
Roaming - Not roaming
Mobile network state - Disconnected
I suspect that I might have the wrong "Mobile networks" settings in the Settings->Wireless & Networks->More section. For the Preferred network type, I selected "GSM/WCDMA/LTE", but I've tried a few others with no positive effects. For System Select, I'm set to Home Only. If I try to search for available networks, it returns an error and doesn't find any.
Any ideas? Thanks!
I was reading more into this, and people on Sprint found this issue when using Cyanogenmod last summer. I don't know if a solution was found, but the workaround was switching the network type to CDMA only, and then switching "back." The "back" is the key for me (I hope). What should it be set to? I don't remember what it was before I started messing around. It may have been global, but I tried that to no avail. Does anyone have a minute to pop into their settings and check? Thanks!
Hi all, the question i'm about to ask has been asked on the internet before but i couldnt find any satisfactory explanation for it. I wanted to change my Preferred Network Type from 3G to 2G as 3G reception is not available where i live , i read on some forums that using 2G only setting can prevent the phone from searching for 3G network intervally which may save some battery. Now, i'm confused about which mode to choose for 2G , i dialed *#*#4636#*#* and went to Phone Information, then clicked on "Preferred Network Type" which, by default, was on WCDMA Preferred, What option should i change it to? GSM Auto or GSM Only? my phone is an unlocked htc M7_U so i cant choose the GSM/WCDMA/LTE Option (it would hog even more battery i think) . Also , can changing this Preferred Network Type have any effect on anything else besides the 2G/3G Network options? i mean, is it safe as long as i change the Network type to the correct option? Any help will be much appreciated. Thanks.
I think gsm only mode.

should be fine setting to "GSM only", setting it to "LTE/4G only" could make problems, because most carriers don't support calls over LTE (mine would be an example: so if I set to LTE only, I can't make or receive calls, so when it's on auto, it automatically changes to 2G/3G during a call)
You can also just change the setting in:
Settings -> Mobile data -> Network mode -> GSM Only

Thanks, GSM Only it is then.
I've had this problem across multiple roms. My phone will only transfer data on LTE, when I am in an area that does not have LTE coverage, my phone does not automatically downstep to 3g. It just loses data, and shows an exclamation over the signal meter. HOWEVER, if I go into cellular settings, and manually set 3g CDMA it will connect to 3g. All speeds seem normal LTE 15-30mbps, 3g 1-3mbps. I have no idea why it doesnt downstep to 3g on it's own. It's like it's stuck on LTE only. Any idea how to rectify this?
I posted this in the forum for my ROM just to see if anyone knew anything. Someone suggested I try a ##72786# reset while on Sense, and if that fails, try ##786# reset. I've done both of those with no success.
I just tried wiping my device again and starting over doing the hands free activation. Still not working. Anyone seen this?
*#*#4636#*#* choose phone info , then scroll down you will see a drop down list which you can choose from. I think the option you should be choosing is "LTE, CDMA" or the "CDMA + LTE/EvDo auto" , you can play around with other options as it's safe and reversible (avoid WCDMA options they will drop signal).
Also if you are using stock rom try updating prl from Settings > System Updates.

Thank you! I wiped and reflashed everything with a sense based rom a couple days ago. I just verified this setting, and it is set to "CDMA+LET/EvDo Auto" I'm hoping that the issue is resolved. I wont know until i'm in an area where i lose LTE. Thanks for your help.
