Conecting to 3G

hello,
after searching on "3G" in the forum, i seems that the problems are just the opposite to my question, they all want 3G to be turned off.
Now I want to connect to 3G (with the "G" icon on the staus bar).
My problem is that it always connect on "edge", with the "E" icon in status bar and when I want to make a video call, it always says that there is no connection to 3G so I can't make videocall.
Anyone knwos how to activate 3G?
I looked into the connections, but I don't want to mess in it without knowing what I do.
BTW I'm in Europe (Belgium).
Thanks

You fell into the same trap I did when I first got a Windows Mobile phone.
G means GPRS and is the lowest, simplest connection speed.
G = GPRS. "Normal" internet speed (9.6-14.4kbps)
E - Edge. "Enhanced" internet speed (normally 48kbps, but can be higher)
3G = 3G internet speed (128-384kbps). Also allows video calls.
H = HSDPA. "Mobile broadband" speed. (1.8Mbps, 3.6Mbps or 7.2Mbps depending on operator).
You'll want to go to:
Start > Settings > Connections > Advanced Network
Make sure that HSDPA/HSUPA is enabled
From then on, it depends on the signal in your area. If you find that you're having a problem getting and maintaining a 3G or H signal, you might need to get an updated SIM from your operator. I got a new SIM from O2-UK and it solved my connection problems immediately.

I see that HSDPA/HSUPA is enabled.
Could it have something to do with the settings in connections (instead of advanced network settings)?
I will also check with my provider (sim card)
Thanks for the reply

i cannot connect to the internet not using wifi. i do however h an H symbol next to my signal. i dont get why i have the hsdpa but cannot connect. i've tried anything i can think of.
*i can't turn data connection on in my comm manager, it automatically disconnects and says wap.cingular not working or gprs not working somthing like that.
*in the connection settings i pick media net wich is automatically picks att but still won't
*in settings/personal/phone i left if auto defualts for bands
*settings/connections/advance network i even tried to put it to hsda ONLY won't work
the only new lead im getting is this Zenith post saying he got new sim card so now it's working. that's all im getting at now. but im even skeptical about that

If you are not getting the 3G or H icon then you either have no coverage or an incompatible SIM.
If you can't connect to the internet you either have incorrect settings on your phone, or your network aren't allowing you on their APN.
Suggest in all cases phoning your network to get clarification.

you wouldn't believe how i found out i had no internet. they say'd it was in the system but it was disabled in thier system. i put in my brothers sims and his work just fine. so i told them to look at whatever his plan is and they switch to what he had. anyways long story short i found out not my settings bc you just auto configure it connectin wizards, and wasn't sims card, it was stupid att. i was getting the H icon but not an H on my signal. anyways its all done now. thanks again guys

How to Disable 3G?

Does anyone know how to turn of 3G as its sucking my phone dry and it lasts for less than a day. i installed a cab file and now i no longer get the 3g connection in the manager. Is there another way to disable it as i can see it switching between the networks and 3g is on and off like crazy.

U should really considering searching before u ask something like that
going to phone>menu>options>band is the same as going to settings>phone>band.

i checked the options in connection manager and advanced but never saw anything which said 3G, is it a band setting i need to change instead, if so what is the band setting to not use 3G?

WCDMA = 3G. So just set network type to "GSM" instead of "Automatic".

[Q] Option to use only 3G NOT HSPDA

HI all!
Right now I am using [Build][10.12.2010][NexusHD2-FRG83D V1.8 PPP+RMNET][Kernel: hastarin r8.5.3_oldcam] and that is quite ok for me.
However I havent found anywhere on that build an option to disable HDSPA speed.
What I would like is accept 3G but disable HSPDA. Now I only have a change to disable 3G totally and only get 2G. Basicly area where I live is keeping me a situation that phone is very often trying to connect HSPDA but then changes is 3G speed. It causes me time&battery drain.
I have found a solution to force phone only use 3G but that is what I wanted. 2G and 3G are ok but I want to disable HSPDA.
Anybody could help me?

Up, Up... anybody have same kind of need?

i also need same help regarding this, reason is my data plan only use 3g (umts) and not 3.5g (hsdpa)... but my android always switch 3g to hsdpa back and forth and drain battery much faster
is there any tweak/program/widget/application that can enable 3g (umts) only?
windows doenst have this problem cause in winmo i can switch the option easily (enable/disable hspa)... but android dont have this kind of thing

I have the same problem. I don't even have HSPDA where I live, yet it tries to connect, fails, and then connects to 3G. It's a very time consuming processor to wait for the phone to do this when I am just trying to load a website.

Yes.. maybe it will not drain much memory but.. who wouldn't want a fast internet..

Afaik Hsdpa uses the same radio towers (or whatever the name is) as Umts... just different software. so there should be no battery drain caused by this.

This mite help you
1. Go to your dialer
2. Dial *#*#INFO#*#*
3. Click 'Phone information'
4. Scroll down to the first dropdown selection and set according to your preference below...
For simplicity, there are two main types of cell carriers, GSM and CDMA.
The following popular data communication technology is associated with each cell carrier type:
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Now that the general stuff is out of the way, here's my take on the Preferred Network types:
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

uhh... maybe you dont catch what us mean....
when umts change to hspda (icon change from 3g to H) then it use battery power.. in my case i use 3g (umts and not 3.5g or hspda )data plan only... but android keep searching hspda signal and THIS is when battery used the most (the process) and EVEN when my area have 3.5g covered but because i use 3g only data plan... then the back and forth process (3g<->H) will kep coming and rdrain my battery fast
so... we look for any kind of workaround so our android keep stay in 3g (umts) and not drain any unnecessary battery power searching for hspda
btw sorry for my english

i use this thing before and no luck
i use "wcdma only" as the option and android still process 3g and 3.5 back and forth, maybe android "thinks" 3g/umts and 3.5/hspda as the same?? android categorize umts and hspda as one big fat 3G network
i wonder why newer os like android doesnt have this kind of feature in winmo there is an option :
disable hspa = so hspda disabled.. AKA 2G or UMTS only
enable hspa = enabled hspda, hspa, hsupa etc.. AKA 2G, UMTS and HSPDA

try this settings
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.

isnt cdma auto (prl) used exclusively for cdma phones? (those phones with evdo and wimax thing) and not used for our hd2 (GSM)???

C'mon how this is impossible with newer phone software??
This feature has been in WinMo and Symbian in many years!!
It is really frustrating that almost every time my phone is trying to make HSPDA connect and then decide 3G is enough and possible. It causes some delay and sometimes also timed out errors.

agreed
my android keep going back and forth between umts 3G and hspda 3.5G like some clueless kid while 2 experienced guy (symbian & winmo) laugh at him

i know this is a old topic
i have still this issue
my phone is switching to hsdpa an back to 3g after a few seconds
when the phone is connected to my slow wifi connection everything works fine and i can use it for 3 day's
when it is connected to hsdpa my battery is empty after 15 hours and the voip connection is not working properly (i need to start a ping to some server first to keep the connection alive so i can call with voip)

I just came upon this thread, but I don't have this problem, so I can't really test it out this theory. But my thought was, what if you just went into the build.prop file and edited the ro.ril.hsxpa.category settting from ro.ril.hsxpa.category=2 to ro.ril.hsxpa.category=0. I just tested it out and it never jumped from 3g to H. My only concern is that you wouln't get the fastest speed you could be getting. Test it out and let me know though.

at this moment it is not posible to root my phone (SE Xperia pro with latest firmware)
so i am afraid we need to wait to test this
but thanks for the hint

[Q] No data connection when switching between gsm and wcdma

Hello!
I'm using Rafdroid HD von my HD2 now for 2 weeks and I'm verry happy with it, i just have one problem (dont know if it depends on de android build or on the hd2 or whatever...)
I'm using gsm all the time because it has less battery drain in stand by, but when i want to use data for surfing etc. i switch to wcdma. on my x8 wich i had before this was no problem, it switched within seconds between the networks. Also the HD2, BUT it doenst start a data connection. i just can talk but no data.
in "wireless and network" the option for wireless data is checked, but the whole option is not clickable and it says "starting" (dont know if it says starting, i use the german version, there it say "einschalten..."
when i restart the hd2 then the data connection is working. so all times when i want to switch the data connection i need to restart my hd2.
is there a way to solve this problem?
sorry, i've searched the forum, but i haven't found anything
thanks and best regards, chris

No one who knows something about this issue?

tried this yet??
enter: *#*#4636#*#* in your dialer
go to phone info
go all the way down
now you can manually switch between edge or 3G
(default should be WCDMA preferred)

Thank you, I've foudn this idea before but it doenst change anything.
I'm using the whole day only gsm/edge, but when i need more data (searching something on google etc.) i would like to switch to 3g. after this, back to wcdma. on my x8 this worked well, on the hd2 it looks like it cant start the data connection when switching between the two types of network...

Same here,
when running runnymede rom from dung my phone switches to WCDMA (in *#*#4636#*#*; because of this I have no data connection 3G or HSDPA. When switching back to GSM only data conncetion (3G or HSDPA) is working but after a while phone switches back to WCDMA preffered.. How to change this into GSM only as default???

switch between 2G and 3G

Hi I have a L720 and made him sprint sim unlock, I'm using it in Argentina with the "claro" position the company APN and it works, sign up both 2G and 3G and the mobile internet works fine. however my question is this, in the menu of this phone does not let me change mode, GSM / UMTS network can not choose one or the other, I can only make it automatic, it is not a stock ROM that lets me choose 2G or 3G. can this be changed? or stays like this forever? I need to use that in my area 2G 3G works very poorly and do not come calling me ..
from already thank you very much.
