[Q] Preferred Phone Network Type

I just wanna know if this detail is right on my preferred network phone settings.I've got WCDMA (Preferred) selected,while other settings like GSM/CDMA etc were not ticked. Is that the right settings "WCDMA (Preferred)" for a mobile network in UK and on 3UK network?Thanks

WCDMA is also referred to as UMTS which is the technology behind 3G, so WCDMA (preferred) simply means that it will use 3G when it can.

oh,cheers for that.Now I get it

Sorry couldn't ask in CM7 development thread

Hey CM7 users, I've just flashed to CM7. Loving the effects and options. But out of all other useful options, I failed to locate the option to have a fixed 2G/3G connection. Yes, I have the option for fixed 2G connection but what about 3G?
Help needed thanks..

Put this into your keypad, *#*#4636#*#* (*#*#INFO#*#*) press Phone, scroll down and choose "WCDMA Only".

it is happened to users who using wcdma or other non-cdma users.
Go to Settings -> Network -> choose CDMA subscription -> check RUIM
then open dialer,type *#*#4636#*#*,phone information,choose Select prefered network type to WCDMA prefered, reboot
now you should get signal on your phone,if not,check if network type is LTE,then switch it to 3G or 2G,then it should have signal now.
press the thanks button if that helps you

Hi
It seems I got the issue resloved by running into another issue. First of all there is no such settings in my menu and second off all all the codes I try and when I press the last corrector the whole code disappears and nothing happens.Even *#06#
doesnot work
Also there seems to be a signal dropping issue. btw I am using F180L which is similar to E975
Also Thanx so much for trying

How to switch 3G Only

How I can switch my Fire Phone to 3G Only Band? Some App or somthing? Who help? :what:

Go to the dialer, enter *#*#4636#*#* and tap "Phone Information". On the next screen, you can select 'WCDMA preferred' from the drop-down menu. However, I'm not sure if the phone will automatically reset itself back after a restart or whatnot.

Yes. I discovery that. Its simple and easy. Now for me, a very good phone.

Is there anyway to turn off 3G ? for use 2G GSM only mode , I want to use EDGE option since my area has the weak 3G signal.

You follow the same steps I gave in my previous post. Instead of selecting WCDMA preferred, you select GSM only in the drop-down menu.

Thank you it works great without reset the phone.

And easier and lazier way is to install the app "Phone testing", it is the shortcut to the same menu. On Motorola phone the app is required because that dialer combination doesn't work.

LTE problem

I live in a place in Southampton in which my service provider works on gsm and lte only. My phone with v20a keeps changing my preferred network type from gsm/wcdma/lte auto to a default (I don't know where this is declared) gsm/wcdma preferred. Any piece of advice on how to change this?
Thank you in anticipation!

Try APM+ (Xposed addon)
It gives you the options to customise the power menu and one of them is a 2G/3G/4G switch

Well..
To be honest there is no point in having a toggle, i just want a solution so that my phone doesn't automatically change back to wcdma from lte after a while...i think its something in the settings
