My SG2 is set up in network mode with GSM/WCDMA(Auto mode).
When I’m home the signal strenght, WCDMA, is -101 dBm 7asu and the voice quality is very bad, almost unusable.
When I manually switch to GSM the signal pops up to -73 and 15 asu and I can talk with a sound quality as it should be.
To me it seems that the phone doesn’t switch to GSM, or too late, when the WCDMA signal is bad.
I have tried quite a few different modems for the SG2 but I can’t see any difference between the versions. Maybe it’s the network provider that manage when to switch?
If would be great if someone could give me some info. on how the switching between WCDMA and GSM works, and the thresholds.
GSM auto (PRL) will favour GSM over 3G.
I am not sure if it will work with your network, but you can only try...........
There are a few apps around that will do it, or you can just use the following:
1. Phone dialer *#*#4636#*#*
2. Phone info
3. Set preferred network type to : GSM auto (PRL)
Edit: I am not sure if it will revert after a reboot.
This post was rather useful info, although different phone and network, principle is the same:

Hi there,
i have a question related to internet speed
In setting there is 3 options for choosing internet data
- 2G only
- 3G only
- automatic
in my countries 2G is horribly slow
When i access to internet i change to ''3G only'' but the signals i receive can be 3G or H, i only want ''H'' signal not 3G because 3G is still slow for normal surfing!!!
how can i change to ''H'' only?
I have been watching for my 3G/H icon in CM7 and it seems Atrix uses 3G only for standby (maybe 3G mode drains less energy), when data starts to transfer it automatically switches to HSDPA mode. So you don't need to change it to HSDPA manually

Your phone should jump to HSPA if it is available, or else it will use UTMS.
Flash the latest radio. After that I can switch networks as I want.
You can not just change to H. Speed depends of coverage in your area. Phone will use the best and fastest available speed/network. You can force 3G but then with just 2G coverage your phone will be off line.

That's right. I can use just edge and it works just fine. 3g is not the best in my area. You cannot force H. Correct.
Depending on your Rom, when it says 3g, it will be because you're not using data at the time. Then when you're using data it switches to H. I say depending on Rom because for example, I'm running Alien, and it says H all the time.

Was just curious about network settings. Under the hidden menu my prefered network is set to wcdma prefered. Is this the best setting to use? This will still allow lte network correct? Thats what mine is set to default and if I try to change it it goes back to wcdma automatically. If im thinking correctly wont this automatically pick the fastest network available to me? Including lte? I camebto this conclusion because I do get the 4g symbol when Im in the signal area for lte. Also what kind of speeds is everyone getting with LTE? THANKS for the help! Just want to check and make sure this setting isn't preventing me from getting lte speeds.
The menu setting that you see is to only use one of the the technology's and the bands those the technology's uses to connect to the network (e.g. gsm,wcdma)
BTW. None of the l9s have LTE the l9 2 might

Hi guys, just a quick question here. My LTE (4g) is hit and miss so I currently have it set to WCDMA preferred/GSM.
Is there such an option that can give me WCDMA preferred/LTE? (So that my phone can automatically switch to LTE in areas where's its stronger than WCDMA)
If I have it on default LTE preferred it will only switch to WCDMA when LTE is non existant which is useless. I just want it to switch to what ever has the highest signal.
Cheers ?
UPDATE: Use the app to select "LTE/CDMA/UMTS auto (PRL)" which starts as LTE but will switch to 3G to make voice calls. if you force LTE alone then voice calls won't work.
This is simple once you know how but otherwise most would probably assume a 3G only area or forget the device is actually 4G capable. So this another eccentricity of this model. I was told that I should definitely be getting 4G/LTE at my address when the phone would only connect to 3G. But various guides recommend changing "Network Mode" to force 4G. However this model does not have this setting. I had to install "4G LTE Switcher" and switch to "LTE/WCDMA" and now get 20.7 Mbps according to Google Speed Test, when on 3G I was at 11 Mbps.
