Hi..
Anybody knows how to switch manually to use 2G or 3G only?
Because sometimes when I am on the 3G coverage area, the phone still use the EDGE data connection rather than the 3G/HSDPA data connection. It really annoy me because the speed is slow if I use the EDGE connection.
In my old nokia, it allows me to use the 2G/3G connection only, so I wonder if desire can also do that.
Settings/wireless & networks/mobile networks/network mode. The auto is however set up quite well. The reason you keep finding edge, is that the edge signal might be stronger that the 3G. 3G will always be the preferred option for the phone, but keep in mind that a strong signal on edge will beat a poor signal on 3G where download speed is concerned. Therefor your phone tends to pick the fastest/strongest signal in your area.
Hello everyone at XDA
I have an Xperia Play r800a (Rogers Canada)
I was looking in the menus and I remember reading somewhere that if I change the Network prefrences I can get better battery life.
So I was wondering out of these options under Settings> Wireless & Networks> Mobile Networks> Network Prefrences
I have these 4 options
GSM/WCDMA (auto mode)
WCDMA only
GSM only
GSM/WCDMA (WCDMA preferred
What settings should I choose to increase battery life? Also I almost never use mobile data since I am always near wifi.
if you dont use data really just use the data toggle to turn it off till you need it(Way way more battery life)
or if your like me and always need a little data present for google voice and and 4g every once in a while when actually using net then Gsm(= 2g and increded battery life over but 4g connection by couple hours) but alot slower than 4g
then just 4g when you need it (3/4g=wcdma)
auto just choses strongest signal no preference
and Wcdma perfed is just that if both signal available it uses wcdma but if not then then gsm
so for you if no data ever hardly and no constant connection needed then
wcdma perfered and a data toggle by ether a theme with notification toggles or the data switch widget or widgetsoid
hope i helped
Do you know which one would have been the default?
So from what I understand GSM only and data off gets me the best battery life?
For my phone GSM/WCDMA (WCDMA preferred) is default option.
And yes, GSM only and data off gives you the best battery.
I recently switched from AT&T to T-Mobile, and like the rest of us was suffering without 3G due to our lack of compatibility with the 1700MHz WCDMA that T-Mobile uses. One of my friends (a T-Mobile employee), however, informed me that it is indeed possible to get 3G by using the 1900MHz band, which T-Mobile is currently re-farming to support WCDMA. This trick is simple and easy, and I've had success with it thus far, albeit only in one location as of yet. There is a downside, however... as long as the trick is in place (as long as your phone is set to "WCDMA only" below), you cannot connect to EDGE. In other words, in an area where there is no 1900MHz 3G coverage, this process must be reversed to fall back to EDGE. As such, you may lose connection randomly and be completely unaware of it for hours, and I will mock you openly for attempting to blame me if you lose your job because you missed a call from your boss, lose your girlfriend because you stopped texting her, or lose your bacon because your remote bacon-protection app couldn't connect.
Remember, this is in the testing phase. It WILL get better over time and hopefully one day we won't even have to consider whether a phone supports 1700MHz... for now, though, report your findings below, preferably with location, signal strength/type, and down/up speed.
==PROCEDURE==
Go to dialer and enter *#*#4636#*#*
In the menu that pops up, tap "Phone Information"
Scroll down to the menu labelled "Set preferred network type" (it should be the first one) - this will likely be set to WCDMA preferred
Change it to WCDMA only
Switch to your main Settings app, then navigate to "Mobile Networks" (under "More..." by your Wi-Fi and Bluetooth)
Tap "Network Operators" and wait for the search to complete
Tap T-Mobile if it appears in the list
Once the phone has acquired a signal, you can return the Network Mode setting to WCDMA Preferred. Your phone should now switch back and forth between EDGE and HSPA+ fairly reliably.
===My Results===
At my home (approx. Colfax and Yosemite in Aurora, CO) I get 0-2 bars, mostly 3G but some H+ if I'm holding my phone and moving around, and 2-3 bars H+ if I set my phone down. Speedtest results range between 4 and 10 Mbps, with around 90ms ping. I've been keeping my phone set down with wireless tethering enabled, and it's been 100% usable thus far.
--Update--
Having used it daily for a few weeks, I'm pleased to report that there is moderate to good connectivity to at least 3G in most places. I still find myself on EDGE regularly, but I usually can get a WCDMA connection. Now, however, I'm annoyed because I exceeded 5GB data usage and am being throttled to below-EDGE speeds, which defeats the purpose of having 3G. >_<
what about AWS band ????/ its work

Almost certainly not; see here.
If you have it working for some reason, go over there to tell everyone.
I'll test this later tonight. I'd be cool with 3G or H+ if it works. I have a T-Mob pay-by-the-day sim card that I'd like to use to tether my Nexus 7 to when I'm traveling (which is fairly rare).
I'm new to all this but how is this different from changing the APN settings?
Is this method better than changing APN settings?
This didn't work for me, Portsmouth, NH. It picked up the T-Mobile network in Network Operators but when I tried to select it it took forever and then said unable to connect, failed to register. Attempted a few times on a ucdlk3 stock based custom rom (Intergalactic II) and also on stock rooted.
Probably just not in a good location for this to work.

I live in a non LTE area (Rio Grande Valley) and was having slow data speeds. I would average from 1-2mb dowload and .4-.7mb upload. At times speeds would run super slow and .4mb download. after changing the network mode to WCDMA/GSM (auto connect) my speeds have increased significantly to 6-7mb download. tmobile keeps saying there working on upgrading to LTE but in the meantime its best for your s4 not to search for LTE if you don't have it in your area. I think it saves battery too!
* Network mode is located @ settings/More networks/Mobile networks/Network mode
*Hope this helps someone

To add; if you don't even have 3G, take it a step further and enable "GSM Only" for even better battery savings. AOSP has a toggle in the settings menu "Use only 2G networks" which does the same thing.
Being in a rural area, sometimes it is better to have full 4G data over one dwindling bar of LTE.
Under Settings > Mobile Data > Preferred Network > GSM/WCDMA/LTE, you may select "GSM/WCDMA auto" to keep the phone out of LTE, but it seems it for me that this kills data altogether- only voice connection remains.
Does anyone have a recommended way to achieve this properly?
