I have seen a few postings mention this.
Dial *#197328640#
This brings up the debug screen (service mode)
I unlocked my T-mobile Samsung Galaxy S4 and I am trying to use it on an AT&T mnvo but I do not get any data service. So I am wondering if the bands need to be changed in this menu or some other menu on the phone?
Does anyone now this information? I am trying to determine the cause of no data on my Red Pocket sim card. I have the APN Settings correct and registered on the Network but still no data connection.
Does anybody know service code to access service mode on Galaxy Note 8.0 LTE (GT-N5120)?
I am trying to find Network Mode on my Samsung Galaxy Note 2 to switch to 3G but I can't see the "Network Mode" option in there.
Is there any other way to switch to 3G from 2G on Note 2?
It's an unlocked ATT Note 2.
Thanks
HI ALL,
my lg g3 f400s have this problems in LTE network. before some weeks all going good but now
when i connect only GSM mode it works great, All signals good and connected to network.
When i connect to forcefully LTE Only mode or Auto mode, it shows Emergency mode only, where as i connected to band 3 (1800mhz) which my service provider band and also have in my lg g3 f400s band.
1. In LTE mode where phone shows emergency mode only, signals bar shows full signals.. setting>>about>> network shows signals strength in some values in dBM( it means it have signals LTE) .Service State shows ( Out of service).
2. when i enter in to Hidden menu LG g3 *#546368#*400# >> modem settings >> Engineering Mode Here LTE signals shows, Bandwidth also shows
but
EMM STATE : DEREG
SUB STATE : LIMITED_SERVICE & some time it shows ATTACH_NEEDED
RRC : IDLE
GUTI : FFXXXXXXXXX

Whats your Carrier?
Check your APN settings.
Sent from my LG-F460L using XDA-Developers mobile app
Its Warid Telecom, Apn settings as warid. And saved.
I think Its not apn issue. Due to only gsm worked, not convert in lte network.. Before some days its automtically convert into lte but not now..
long story short, my kid messed with the service mode *#2263#
band selection and now it doesn't work properly.
it there a way to reset the service mode to default settings or
does anyone know what should be selected ?
obviously it's a SM-N910A
selecting band in service mode note 4 at&t
type *#2263# in phone keyboard to enter in the service mode. then click on no 8 option Automatic you will see SET: Automatic. click on it. Thats all Your mobile will automatically set bands according to your carrier.
