Disable HSDPA and revert to 3G?

Any way to disable (release) HSDPA/HSUPA like on Samsung ROMs via secret codes? Using 3G instead of HSDPA saves a hell of a lot of battery!
Even going down to 2G (GSM) suffices for exchange push sync or any mails for that matter.

Settings -> wireless and networks -> mobile networks -> network mode -> GSM only.
This way it will enable just 2g, as 4g is just a push up of 3g.
In short you can not just get 3g.
Either 2g or 4g.

What you get is
3G+HSDPA
OR
3G+(HSPA+)
The phone should automatically switch to 3G when idle to save power ... Mine does pretty quickly

mine doesnt switch automatically.. it does ONE TIME. but after reboot, it's just constant H. ( yes I do have separate H and 3g icons in my framework)

thanks all for replying!
i don't have the 4G model, the fastest network we have is 3G/HSDPA 21.6mbps
actually let me test how the phone battery holds up with "H" before i try switching to "2G"...
thanks again!

How to Fix AT&T Data Throttle Your 4G - Your Data Usage is Among The Top 5% Of Users
There is a nice little APN fix. Just change the APN to Phone and force your phone to use HSPA in your phone's settings. I have instructions with a screenshot...
http://www.traemcneely.com/2011/12/...rottle-4g-data-anti-throttling-trick-for-att/

How do you perform the first step on the skyrocket?
1. Go to Settings > Wireless and Network > Mobile Networks > Click Network Mode and force your phone to use GSM/HSPA (Auto mode).
I don't see "network mode".

Click Access Point Name..
I am now getting 512k vs 150k.

Found another trick.
I named the access point the same ATT pta, then I put Phone under the APN setting.
Put your phone into GSM/HSPA (auto mode) let it connect to the network,
then go back and put it as HSPA only.....I'm getting 1-2g+ bypassing the throttle using HSPA+ works like a charm.

Att Throttle Samsung Skyrocket
i did all when i click on Mobile networks i see access point names and network operators and use packet data. When i click on network operators is says Default setup doesnt allow me to do anything. Please help

Same here. Don't see 'network.mode' selection. Please help. Does it have to be rooted?

I am still not sure where/how to pick "GSM/HSPA (Auto mode)" on stock rom. Thats not an option.
What I have are:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this
(Cut n paste from another thread, dont know if these are applicable to Skyrocket/LTE)

Thanks for the pointer to the thread but my whole point is that I dont see those options and for some reason my network mode changes dont stick.
So if I disable packet network, switch the APN, change the network mode and then enable the network again, I see that it has gone back to GSM?WCDMA/LTE auto mode again.
So for some reason my network mode changes dont stick. Also, I am on stock rom, could that be the reason!

Custom ROMS give you the options you are looking for.

I am confused ! If the stock radio is *locked* to use LTE if available, why are some people reporting to lock onto HSPA+ network with stock ROM. Are they exploiting some bug?
I have tried various things but I cant switch my radio to anything except GSM/WCDMA/LTE auto mode. It seems to come back to that mode.
Do I need a reboot after changing the mode.
I am using *#*4636#*#* to switch the mode.

Switching APN 's worked like a charm ;o)

maybe in ur city/area 3g services are not available by ur network provider. try contacting customer care services of your network.

if u use wcdma setting ur device will search for available 3g network. u better call 121 and ask customer care executive about 3g services in ur town. if they confirm that 3g is available in ur area than complain about 3g not working ur device they will guide u for making correct settings.

Go to Settings -> Wireless & Mobile networks -> Touch on Mobile Networks.
Click on Access Point Names:
If you already have settings click on TATA DOCOMO INTERNET.
If not you can send SMS “INTERNET” to 52270 and save them default settings.
If you are not getting Settings for some reason.
Follow the steps:
in the Settings page click menu > NEW APN.
Enter the details as below:
Name : TATA DOCOMO INTERNET
APN: TATA.DOCOMO.INTERNET
Proxy:
Port:
User name:
Password:
Server:
MMSC:
MMS Proxy:
MMS Protocol: WAP 2.0
MCC: 405
MNC: 034
Authentication type:
Apn Type: default.
See if the above works

I had faced the same problem before! All networks work only on gsm mode by default! And 3g works fine on the same mode.. Its just that you need to get the right settings from your network provider and get 3g activated at your provider end!

just if u knew....
before some dayz back docomo gives us access to its 3g network without subscribing to its 3g plan,which is giving speed abot 15-20 kbps...
but frm past 10 to 15 dayz its not giving us its 3g network without recharging with its 3g plann....
do u recharged with its 3g plan??

I faced the same problem while I was using airtel. I sent them an SMS requesting for the 3g settings after which it was solved... you should probably send an SMS asking for the settings...

@vikas145, Is it that you bought your mobile just now and configuring the settings? If so, try to do a factory reset first and then reboot. 3G will work perfectly.

Try selecting manually

guys 3g is still not working on my SGR plz help out...... on selecting wcdma in network settings there's no network on my phone......so what to do with it

You have to activate 3g pack ,then only H or 3G symbol will appear.
Otherwise ,you will get edge network .
I am also using tata docomo and same thing had happened to me.
Tata docomo cancelled giving 3g network on 2g pack activation from january this year.
For testing you can activate Rs.9 (10MB) 3g pack.make sure that you are in 3g area.

If u activate 3g pack,then the network automatically switches to 3g or H network from edge(E).network selection should be auto mode(WCDMA/GSM).

hi guys i have huawei g630-u20 and i use it in iran.
my problem is switching between 2G or 3G network type.
my phone dont have network type option in settings and my phone dosen't support this code(*#*#4636#*#*) to accses phone managment.
i manually search network and select my 2G carrier network but my phone change it again to the 3G network, i think my phone is basically set on 3G/2G (prefrred WCDMA) network type.
what can i do to swith my network to set my network on only 2G network or 3G network?!

can anybody help me?!

Try to modify buil.prop with
ro.telephony.default_network=x
0 = WCDMA Perfered
1 = GSM Only
2 = WCDMA Only
3 = GSM/WCDMA (auto mode, according to PRL)
4 = CDMA / EVDO. Perfered

tnx buddy.
