Hi, i have changed setting of prefered bands with *#*#4636#*#* and everything worked fine.
But after a reboot, the data connection has gone and also APN settings menu.
as u can see on screenshot "Network Mode" and "Access point names" disappeared
Please help!
Why did you change the Band setting??
A simple factory data reset should resolve it
I would revert the settings back to how they were and see if that works
You may have set the phone to be incompatible with your sim/service providers network frequency

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 know the *#*#4636#*#* trick. So I selected 'Evdo Only' in 'Set preferred network type' menu from dialing *#*#4636#*#*. However, the change didn't stay after a reboot. The preferred network type went back to 'CDMA auto (PRL)' after rebooting. Is there a way for the phone to remember the change after reboot? Or I have to flash a customized PRL? Thanks
Hi OP3 Users,
I am unable to find a setting to change the Network Mode for sim 2 in the stock (non-rooted) 3.1.2 firmware. Is there any way to change that.
SIM 1 has that setting; namely "Preferred Network Type" (and has options "LTE Recommended / 3G / 2G")
Also, i tried using the *#*#4636#*#* code, but it shows nothing but "Testing" and has no options to choose in it.
Any ideas on how we can resolve this?
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,
Bearhawk
