Any Way To Force Hsdpa Alone???

As the subject states, is there a way to force HSDPA alone on 3G enabled pocket pcs (using Polaris) without it going back to 3G.. a kind of way to keep data request on so that hspda wont go back to standby.
Thanks

I have same problem.
I live in HSPDA supported area, Kaiser gets full H bars etc, but my Kaiser keeps switching between GPRS, 3G and EDGE for some weird reason

Hi Guys,
You can't force your handset to only use HSDPA services. HSDPA will not be enabled until you start a large download or stream services that require higher bandwidth. The BTS (base station covering you) is informed by the controling switch when to give you an HSDPA bearer, this is triggered by your data throughput. If you are not downloading a large file etc then you will not be given an HSDPA channel. This decision is always taken by the RNC (controling switch) and cannot be forced
There are a few reasons why you might switch between 3G/HSDPA/EDGE etc. These are primarily based on RF conditions - if your received signal strength falls below a certain level (decided by the network planners) you will be forced to handover to 2G (generaly a stronger signal if you live on the edge of 3G coverage) Some networks also have load based handover enabled - therefore if you serving BTS is getting highly loaded it will then hand you over to 2G/EDGE and you cannot force this either. You can of cource force you phone to only lock onto the 3G network and ignore 2G, then you will always at least get a 3G bearer but this will not guarantee HSDPA service - this will only be given if you have good enough signal and if you are using enough throughput. Forcing to 3G will of course increase the amount of call drops you have as you will not be able to hop onto another carrier
Sorry guys!!

^^^That's funny, when I was in an HSPA zone with my Fuze the H stayed on all the time... For that reason, I think you must be incorrect. Sitting there doing nothing, transferring data, didn't matter, always showed H when it was available. This happened in Boston, Albany, and NYC... So it's surely not a fluke based on the area. My data usage at the end of the month wasn't ridiculous either, so it wasn't constantly sucking data for any reason.

bumps.. i would like help on this too coz i use my phone for tethering and it always lags coz when the connection stays idle it switches to 3G instead of remaining on HSPDA..

Im not sure if this wud do but u cud try .. open up dialer n dial *#*#4636*#*# -> Phone information scroll down and there's selection of network type .. try WCDMA only?

am i correct to say that based on your explanation, switching from 3G to HSDPA is cell station controlled and not controllable via our handphone?

How do I select UMTS/WCDMA mode only?

Well guys I am a newbie to the Android world!!
On my earlier Nokia I used to have three options for the Network Mode under the Phone Settings, viz. , Dual Mode, UMTS, GSM. Since in my area the 3G signal is a bit weak I used to select UMTS only, so that the phone doesn't switch over to 2G automatically.
However, in my android device (Samsung GT-I5503) the only option under the Mobile Networks which is anything similar to a Network Mode selection is the Use Only 2G networks checkbox. I believe it disables Dual Mode and allows GSM network only, in the Android device. So Android Gurus and Forum Moderators, do you guys know of any method or software which can select 3G network only!!
Please help me guys as the 3G reception in my network is a bit weak, Android doesn't switch over to 3G!!
Oh and BTW, I'm getting a really good 2G signal. The Signal Bar is 4/4 most of the time!!

@Mods: Could you please change the title of the thread to "How do I select UMTS/WCDMA only, on Samsung Galaxy 5 (GT-I5503)?"

[Q] Force 3G only in field test

Hi..i owned a Lumia, but a bit frustrated when network keep switching between 3G and 2G.
i just want to stay only in 3G network..
have anyone test the field test by dialling "##3282"?
in there we can change 3G only.
But i didnt know it worked or not..
so far it doesnt change to 2G..

I too used the same test by dialing ##3282. In addition you have to toggle the ENS to OFF position (don't reboot).
When you choose 3G only. It exactly what it means, 3G only, not 4G (LTE) and NOT 2G either. So it will only connect to 3G and hence you are not getting 2G signal.
I wish there was a speed limit setting so we could avoid LTE rather than pure 3G only. Or choose 3G+2G together.

[Guide] How to increase S4 GSM signal strengt

Many of you know that the sore point of this phone is the quality of signal reception. Informing about the mode of action of the baseband, and reading the feedback from users about their various tests, always read from their words unsatisfied a search of a radio version that could improve the reception of the terminal (and thus battery life).
Since I live in a poor signal area on the Vodafone network IT (and no LTE coverage), I thought that perhaps the solution could meet elsewhere. After PimpMyRom installation , under "Device Hidden Menu > Access Hidden Menu > Telephone informations" there is a menù was set to a profile "LTE / GSM auto (PRL)".
By clicking on the drop-down menu, I selected GSM Auto (PRL), then rebooted, and i have greatly improved connectivity to the network.
Below there is a legend about the most important items. Take the test and reported your opinions.
I recommend GSM Auto (PRL) for best battery consumption allowing the automatic signal 2G/3G, preferring to 2G when the 3G signal is weak.
- 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.

I use Wanam 2.0 for I9500

Hi, i`m on SlimRom 4.3 Beta 4
Everytime i try to change my Phone Profile to GSM Auto or something else in the List it crashes and says:
The Process: com.android.phone was quitted.
Any Suggestions what to do?
The LTE is draining my Battery like Hell!

It's strange because is a System related setting that can be changed without problems...maybe in your case this parameter is linked to something other. In my case all went ok only selecting other profile (i discovered that if you select "2G only" into telephone settings, this string change to GSM Only). So my suspicious is related to a linkage to some other driver that won't make you possible to change it.
We have to investigate. However my battery drain seems lowered combined with "Wifi tx power" + "iwconfig" file used for reduce Wifi signal power to 11dB. Other small things and Jelly pure ROM 4.3 will be perfect for daily drainage use

3G data disable while on roaming

Hello,
I know there is a thread for this in Galaxy Note section, but i feel i need to share this for OPO community.
I'm using OPO v33 rom. I live in Mumbai and have a 3G vodafone postpaid corporate connection.
Recently i have been to my native mysore on few occasions, and everytime i have seen the 3G data getting disabled even when the data connection settings are enable on roaming.
I never faced this issue on my nokia lumia 920 which perfectly latched onto roaming and 3G data was available.
On roaming, with OPO, the data gets disabled and i dont get a specific "E" or "H" sign with + noticafion.
I only have the signal bars with small R icon on top of the bar.
Please let me know if there is a workaround for this.
I have also seen this issue on v25 rom aswell.
Note: i have tried setting connectivity to automatic in mobile networks.. and also tried to select the specific Vodafone network. both didnt solve this issue.
Another interesting thing while on roaming: my nokia 920 recognised 2 networks for vodafone.. one with 2G, 3G and another with only 2G. and i could select the first one .. and 3G was getting enabled without any issues.

i think that E and H as well as H+ is only something you can geti n your own country. When roaming, it's always the default for that service prodiver in the country that you will get.
