My question, is it possible to enforce my S2 to use only H+ at all times? 3G is not working in my city, and hate to wait the phone to change from 3G to H+. And when the phone is sleep I have no conection to internet, because it use H+ only when you unlocked it.
Life battery is no problem for me, nor the data bandwidth because I'm using a plan with no restrictions.
Any help would be much appreciated.

Hey, I have an USA T-Mobile Vibrant.
It is rooted and running the Vibrant edition of Darky's 9.3 Final ROM.
I am also using the latest overstock kernal and the honeycomb 2.0 theme from the I9000 forums.
Enough background info. This isn't really a problem as much as my curiosity.
My phone almost constantly is switching back and forth between 3G (UMTS) and H (HSDPA) on my data connection.
It doesn't seem to affect battery life or service too much (though H might be faster), so I'm not worried; but does anyone know what the deal is with this?
Thanks ahead of time!!!

Mine has been doing this lately as well. It's only been happening since I installed my current ROM (Trigger 2.7).
Noticed this just now as well...might have something to do with the mods to show H or 3G.
I wonder if it has anything to do with signal strength. I know that shouldn't make a difference but I can't think of any other reason.

I would agree, but I went to my settings/ phone info/ signal page and the reason it was changing was because it was physically switching between UMTS and HSDPA.
Why? I have no idea.
I do live in a T-Mobile 4G enabled area, though I am not on their so called "4G plan".
I did notice that it did not have this switching problem on Bionix Frost-u2.
So, if anyone has some insight, please help us all understand

I was just watching my signal strength change and it doesn't seemed tied to the change from 3G to H.
For example, it would be around 67dBm and be on UMTS. Raise to up to around 75dBm and be on UMTS. Then it would switch to HSDPA and still be at 75dBm or sometimes lower down to 69-72dBm and still be on HSDPA.
So with that type of cross-over stats, I would be skeptical of that solution.
HSDPA is a temporary data link. If it was on continously the phone would have very poor battery life.
When network server has a data packet for your phone it 'pages' up your HSDPA capability. Your phone can also request HSPA to initiate a data transmission.
The HSPA paging process is similar to receiving and initiating a voice call.
If no more packets have qued at their server or received from your phone after some period of time it will revert to normal 3G battery saver cycling. It has to be re-paged up to reinitiate HSPA data link. The wake up HSPA function does add some initial delay.
So is there a way to force it to stay on HSPA while tethered, for example? (Or always)
I have UK SGS II and I am on the bell netowrk in Canada and I am finding that the 3G/H+ signal randomly drops and I lose connection every now and then. I am always in aread with strong reception as well. Any possible solutions?
Thank you
anyone have any ideas
?
I have the same but it doesn't drop anything, in area's where there is H+ coverage it will show H+ otherwise it just shows 3G.
Maybe you want to enable 3G only on your device so it won't switch between all the time.

I have the same problem here in Argentina. It seems that one of our local operators does not support the 3G/HSDPA of this phone (maybe because it is from europe ? ). Did you try to use the browser and surf the internet? I doesn't work here. Strange, because for 3G we use the 850Mhz spectrum.
What I noticed is that the 3G/H icon at the top is constantly changing from 3G to H and viceversa, even if I stay in the same location...

Do you know how to set it in 3G only so that it won't switch to H+ ??
Thanks!

nevermind!!
this has been resolved. I had to manually change the APN settings.
thanks!
hi guys,
i have the nexus 4 and i have a big problem..
were i live the signal is not very strong so the phone continually switch betweeen 3g and hsdpa and the battery is very very high!
the signal switch 3g/hsdpa hsdpa/3g every 15 seconds.. u can immagine the battery life..
the question is..
can i disable only hsdpa and keep 3g?
if i put only 2g (avaiable in settings) i wouldn't be able to use internet..
I search it on the forum but i didn't found any answer
thanks
any one knows how can i disable 3.5G/3.7G/ HSDPA /HSUPA/ HSPA data connection , i want only Normal 3G data connectoin
because i already have poor internet connection due to network operator policie , and my subsecribed bandwidth , so my phone just, use HSPA but no speed is needed , so no battery drain is needed .
so i can save battery when i am surfing the internet

You won't save any battery by that.
And I seriously doubt you wish to use 3G only. 3G is very slow, compared to HSPA speeds. I do not think any of the operators actually limits the speed to 3G speed (384 Kbit/s, for comparison, HSDPA is 14 Mbit/s).
i know that

i know that ,but, my network operator already have very poor connection , no more than 512Kbit/s , i use it only for chat on mobile data ,

btw, i have a question...: does ''use only 2g networks'' saves some battery?? b'cuz i activate that if iam over my limt, bcuz my provider reduce my surfspeed to 64kbits/s and i thought, that didnt affect my surf speed and saves battery?? right or not?
thanks in advance
Using 2G does save battery in some cases. In city areas, it is not noticeable. From my own experience, I can say, that if I use 2G, the signal is strong all the time (operator's 2G antenna radius is larger than 3G), however with 3G, it goes up and down at my home. If signal is strong all the time, phone has to use less battery to keep connected. If signal is weak, phone needs to use more battery to keep the connection.
Long story short - Yes, it can save battery, however in city conditions, it is hard to notice.

yeah you are right.. 2G network consumes very less battery than 3G
Hi all!
Im using a moto E with Tata Docomo sim.
The problem is that when I change my network mode to WCDMA only, the phone shows only 3G and not H+. However, when I go out of my home, I get H+ with full signal.
I've talked to customer care and the issue is that another cell tower which doesnt support HSPA is stronger in my home so the phone connects to it and only shows 3G even when data transfer takes place. 3G is so much slower than HSPA/HSPAP.
Is there any way I can force my phone to connect to HSPA/HSDPA only?? I dont mind if the signal drops a little. Since it is possible to force the phone to using 3G only, I thought forcing to 3.5G could also be done
Also my phone is rooted so changing any system file is not a problem.
Please help..
Thank you.
