[Q] 2 questions on 3G/H

hi!
i am using a tmous hd2 with the stock 2.13 rom and the recently released 2.15 radio. up till now i havent really bothered using packet data on my phone because i am a wifi guy... only recently did i start using packet data frequently...
i noticed two things out of place:
1) for some reason i have never seen hspa service on my phone. my operator runs a 3.6mbps dl 2mbps ul hspa services. whenever i switch to 3g and connect data, i always get a 3G written over the signal bars. and i have never seen speeds over 42kB/s (~384kbps) in several months of use. i have full signal strength in both 3g and 2g. if i am running 2g, then i get an E as expected over the signal bars. i have put in all the access point settings as defined by my operator (which are common for both 2g and 3g). i have enabled hsdpa/hsupa from winmo settings->connections->advanced n/w. is something amiss with the hspa settings on the phone? i really want to confirm that i have my phone set up right before i muster the courage to call up customer care.
(for someone from bombay, india, i am running mtnl 3g prepaid with following settings:- ap:gprsppsmum u:mtnl pass:mtnl123. this in itself is quite baffling because mtnl delhi has separate aps for 2g and 3g whereas the bombay network has the same ap for both. ap=access point)
2) i have never seen the H/3G/E/G icons on my taskbar. i mean the ones that are NEXT TO the signal strength icons. the space between the headset and the signal strength is always empty. isnt that particular icon supposed to show 'availibility' of the respective type of data connection? i read somewhere a long time ago that the icons are ROM dependent. but i am pretty sure i have seen snapshots of tmous phones with those icons...
i have been using bsnl cellone 3g since feb and i always got H in south india, even while roaming,...in few cities up north, like lucknow, i got only 3g icon displayed..i guess it should be H in mumbai..
from what you say, i think you have not enabled HSDPA/HSPA setting in the phone...do that..it is in settings/menu/all settings/connection manager or ?phone / advanced network ( i think...can't tell exactly where...iam presently on the android side...)

no, i have enabled hspa (both directions) from advanced network. i said that in my original post as well. what windows rom were you running? also did you just get H speeds or see the H icon as well?
both H icon and speeds on 1.48 wwe and 3.14 wwe roms
Hi I use an unlocked TMOUS HD2 here in Italy with the italian carrier PosteMobile and experience the same problem of silenced3 (almost the same as I still haven't tried a cellular data connection): My phone doesn't show the kind of cellular signal available, only when it data connection is activated it says what type of connection it's using. Anyone knows how to solve this?
Thank you for your help...

Can someone help me with O2UK 3G

I have had my phone for over a year now but 3G coverage is so bad , most of the time im on 2g (o2-uk) very rarely does it say 3g o2-uk. it takes ages to get a page due to the fact i keep getting page not found errors.
i rang o2 today and was told to hard reset phone , to update latests updates (both which have been done) and no difference.
i have a 3g sim.
it appears that when it switches to 3g it gets no signal altho i may be wrong
could anyone suggest any tips / tricks to make 3g mode work
Ok I had a similar issue with my O2 reception and the only way I found that helped was to disable HSDPA/HSUPA, I now mainly have a good 3G signal.

[Q] Help about using HSPA

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.

Redim 3 Pro 3Ram/32GB

I Have small problem from around 3 weeks my Redmi 3 Pro don't see any of 3G network if I'm login to network than only 2G or 4G.
Sound very bizarre a specially that most people have problems to set 4G on there phone.
when I try to search for network manually I can see all 4G and 2G only no 3G
I have not found any similar problem on any forum.
Any help / advice?
you are on wrong section sir, you should ask on Q/A section
answer : maybe its hardware related problem, try with other sim card or other provider that only have 3g connection on your area
It's not a bug I think, It rarely shows 3G to me either, only H/H+ which I think it's 3G or "3G+"
