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

3G on and Off

So, i have bugged folks on this forum about getting 3G to work on other carriers, and it turns out - it does work! At first i found out my settings were set to GSM only, but now i also found this weird inconsistency possibly a bug.
If i have Data Off after using 3G or GPRS for some time, when i turn it back on, phone would not connect to data service. After enabling it will simply time out.
I found that if i switch from GSM to WCDMA, and than back, 3G network would connect and work.
I don't know if it's specifically my phone, or a bug, so i'm just throwing it out there.

What carrier are you getting 3G to work? I doubt its working if its anything that doesn't run on tmobiles bands..the icon will come up and stuff but your either getting edge speeds or not getting any connection. I've had this phone show me 3G with full bars and just time out.. I can eveven put in a sim with a sidekick plan or other data plan and it shows 3G but it does not work

Well, i'm overseas and i have used it on Russian carrier Beeline and carriers in two other countries. Now, i do set my connection to WCDMA only, which gives me 3G icon. When i set it to GSM only, i see GPRS icon show up.
So, it does work, i use fring, online radio, google maps. But as far as speed concerned, i have not tested it.
Just ran a speed test using Speedtest.net tool, I get 3951kbps download, and 655 upload
thats 3G

3G mode not working sometimes

Have had this phone a coupla months, happy with it except the stupid GPS problem and some other connection problem.
When using wifi connection at home, if i stop browsing and close the screen for a few minutes and go back to surf internet, the wifi will stop working, turning wifi off and on again will make it work. Not too difficult but sometimes this feels sucks.
second problem is, occationally i will lose the "3G" or "H" sign on the top and cannot connect to internet using 3G data connection. i have no idea why this is happening. sometimes when i am out on street, try to check some information online, 3g is my only option and it really bothers me when it stops working. i'm using orange. all setting are as original.
Anyone knows how to solve these 2 problems?

the phone either works on
850/1900/2100
or
900/1900/2100
so depending on the model that you purchased
and where you live
also the cell phone provider that you are using
you might not get the full band usage of your phone
for example using the above models on a phone service that only uses
1700/1900/2100
then you are cripled
some telcos only use 1 band or 2 bands at most
1700 or 2100 for example

3g nodes and 2g bts wont give you the same area coverage, yes you will lose the H and drop down to 3g if your -db rating (signal is low) is at the highest limit for the cell and it deems you either need handing off to another site or you were one of the last ones to be allocated a slot and get kicked.
its how the cookie crumbles, no where will give you 100% coverage and if u are close to a small site thats overloaded with traffic you will always get crappy uplink and downlink...

I dont know where you are or what provider you use, but I have the same problem with my I900M on bell. it is apparently a widely known issue with Bell, and they associated my phone with the ongoing ticket incase it gets resolved they'll contact me.
Also, when I lose the 3g, ts a good chance my phone is going to lock up and need a battery pull to boot back up.
So Basically if I leave the house or wifi spot, I try not to show people my internet on my phone so it doesnt look like I'm carrying a brick in my pocket everywhere.

so that's something to do with the carrier? Thanks for the explanation!

Only using data/internet with 'H' or 'H+', not 3G

Something strange I've noticed with my Galaxy S II is that data / internet will only work if the 'H' (for HSDPA) is in the status bar, but not with '3G' there...the green arrow will appear next to the 3G when I try to connect to something but it will just time out unless it happens to switch to 'H'.
Anyone know why this would be? Is only the HSDPA network working with my phone, but regular 3G won't?

It is possible that the 3G cells in your area are fully loaded with users.

i didn't read it well

Same problem here, on 3.
Wondered if it was the phone or the network! If it's a problem with the phone it'll be fixable/covered by warranty though, right?

Same here, it sits on 3g then i try to load a page etc and it goes to h like it carnt use 3g , im on t mobile and they have full coverage where i am

I found an older thread that says it's a feature, keeping the phone in 3G mode to save battery until you do something that requires data which switches it over to H. I've kept a closer eye on my phone and that does seem to be what it's doing, usually taking a second or two to switch over each time I use data.
However, there have still been some times where it stays on 3G and is unable to load data.

Yeah i think your right and also it does not change sometimes and kinda hangs, be nice for it to switch over to H abit faster without battery drain.

I have the same issue with my phone to on t-mobile, not working on 3g then working on H.
It is a right pain to be honest.
No way of stopping this battery save? I would rather use more battery.

It's the network. I have no explanation but only Edge and HSDPA work whether on Samsung or Nokia.

Just tested, this does not occur for me, at least right here, right now. Comfortably loading pages on Google with just 3G signal (T-Mobile UK).
It's faster when I stand on my bed upstairs for HSDPA but 3G does work. Stock firmware from T-Mob, no modifications.

Hey mate,
I have the galaxy s i9000, with optus here in sydney. same problem, only switches to "H" when i make some sort of data request (load a page, open an app that uses internet), it takes a couple of seconds to switch from 3G to H. Sometimes, it keeps flicking back and forth between 3G and H like its having problems connecting to H
I complained to optus, they reckon i'm lying. Go figure.

Sorry.. just to add on, i've tried about 13 different modems on my i9000 and it happens with all of them.
The only fix I've come by? dial *#301279# and disable HSDPA altogether thats the only way my phone will actually load any data on 3G

I have the same thing, but as i understand H and H+ are the highest form of 3G, not a different thing. So I am wondering what mode we are in when 3G appears. UMTS?

Its all very annoying to be honest.
None of my other phones have this problem as they always stay on HSPDA

Same problem here to the extent that pages fail to load on 3g and come up with the error then when I refresh the page once its on H it loads straight away.

Actually this problem is making my phone more or less not usable.
I use the slingplayer alot, keeps skipping on the Galaxy S II as it seems to keep switching between H and 3G.
Put the sim card into my ZTE Blade (Orange San Francisco) and streams constantly with no problem with signal staying on H.

With all the threads relating to 3g and connectivity issues..we can deduce that SGS2's modem really sucks big time..and still no firmware update to correct this even though large number of people is facing some sort of problem with mobile internet which is a main function on todays smartphone.

Anyone know who to e-mail with examples at Samsung?
I guess they won't fix a problem if they don't realise there is one.
Some people will prefer longer battery when its on 3G then H, others will want the constant H.

I got mine a week after it released. The first two updates mine did the same thing, but instead of timing out, it would drop all signal and display the circle. After a reboot signal would come back. From KE7, it has not done it again.

same problem, mode switches around when using data, 3 australia

Fix/Workaround for mobile data connectivity problems (3G/H/H+ dropping connection)

I've been following the mobile data connectivity issue that some users are experiencing (where data connection drops randomly, apparently coinciding with a lot of switching between 3G/H/H+).
Initially, people suggested disabling 'fast dormancy' using *#*#9900#*#*, however, this did not work for many, including myself.
In this post http://forum.xda-developers.com/showpost.php?p=15250511&postcount=6, there appears to be a solution, albeit a workaround.
I have started this thread, as there are so many separate threads about this issue, and only the Telstra Australia thread had this answer (as far as I've read). I have copied the post (a repost from whirlpool) by dusty_nz below. Basically, the problem is serious, the guys from Samsung have insisted this will be fixed in KE9, but there is a workaround in the mean time (disabling H+ and H, or just disabling H+ using *#301279#). This may seem drastic to speed freaks, but 3G connection alone should still give you 1.5 Mb up/down if you can put up with that. This has worked for me, no more data stalling, no more server errors etc. etc. I hope H/H+ will be fixed in future firmware.
Here is the post:

****************** FIXED ******************
After contacting Samsung for an insane period of time (ended up on an international call to England i think... or now that i think about it could have just been some English guy in Aus lol) I have got an official explanation and confirmation that this issue is being looked into for KE8 (but it appears that KE8 has been launched in India already so it might be KE9).
*disclaimer*
I am no expert on mobile technology this in-depth however the (probably very) dumbed down version the Samsung guy told me was this;
*end disclaimer*
The problem stems from the fact that this phone has 3 forms of data connection, 3G, HSDPA, and HSPA+.
3G is what we have all had since 3/Telstra launch 10 years ago.
HSDPA is the 7.2mbps connections that we got after that.
HSPA+ is the full fledged 42mbps Next G stuff that only Telstra has.
The problem is, when you are just using the phone as "a phone" it idles on a 3G connection to save battery and when you initiate a data connection it flicks on to the higher connection protocols for better speed.
What is supposed to happen when you initiate the data connection is the phone checks for H+ connection, then for H and then finally 3G. For some reason if you arent with Telstra or are in an area without HSPA+ the phone gets hung up for too long attempting to initiate the H+ connection and refuses to drop back to H!
Also, even if it does give up on H+ it then has an issue with falling back to 3G. Resulting in the problem that if it cant get H+ or the tower is too flooded for a H connection you get absolutely nothing until you restart the data mode within the phone, renegotiates with the tower and BAM, you are back in business.
So... there are 5 fixes;
1. Wait for KE9 (or what ever firmware fixes the modem timings etc)
2. Get a Telstra sim and never leave an area that has H+
3. Turn off/on data mode whenever it happens
to which i told him they were stupid answers and completely unacceptable, but then he came out with this complete gem!
4. using service code *#301279# you can turn off HSPA+ completely forcing it to start the data connections on HSDPA
5. using *#301279# again you can just turn off HSPA+ and HSDPA meaning it instantly starts downloading the data on 3G without delay
Now yes, i thought... great... ive bought this $779 phone that has all the latest and greatest technology and I cant even use it! But, I did some testing!
First of all my normal sim is Vodafone so turning off HSPA+ is an obvious one for me, im never going to get it so why bother. So now that the phone only attempts to get a connection with HSDPA the need to turn off and on data connection was getting more and more rare but still having the problem (i have a feeling that is due to congestion?). So i bumped it down to 3G only and it works perfectly 100% of the time!
The point of these faster connection protocols is speed so i did testing.
Vodafone sim, 4 bars of signal in the middle of a shopping centre.
HPSA+ turned on = 4mbps down, 1mbps up
HSDPA turned on = 4mbps down, 1mbps up
3G only = 3.5mbps down, 1mbps up
did this over and over and over again and to be perfectly honest, im willing to lose 500kbps to make sure that data always works and if you are just doing general web browsing the time it takes to initiate the HSDPA connection wastes more time than the slightly slower speeds with 3G does.
Now obviously this only works fine in my situation, if you are with Telstra and going from HSPA+ down to 3G means going from 20mbps to 3... i would be pissed. But for the rest of the country you are talking about a loss of less than 1mbps so in real world situations with just small amounts of burst data its fine
TLDR; Try and go online and the 3G up arrow lights up but never actually downloads anything
Dial: *#301279# – Change HSPA revision – Release 5 HSPDA only
test, if still a problem
Dial: *#301279# – Change HSPA revision – Release R99 HSPA off
Your welcome, Peace out!

Just tried this and I got 1800kbps on 3g!!

Hmm, i played around with those codes. If i choose to drop H+ and H, stays on 3G, but speed is crappy for me. So i want to drop only H+, but when i do that phone stays only on 3G too, not attempting to connect to H. Am i doing something wrong ?

*#301279#
Option [1] Release R99(HSPA OFF) - This should turn H+ and H off
Option [2] Release 5(HSDPA ONLY) - This should turn just H+ off (what you want)
Option [3] Release 6(HSDPA/HSUPA) - This should turn H+ and H on
To test this, you might want to make sure you are in an area that can pick up 3G, H and H+.
One week on since I selected Option [1] and I have not had any data stalling issues, before I was having data dropping every few minutes whilst browsing.
I tried Option [2] and still had the stalling issue.
Good luck.

I hardly ever get H+, which is why i want to turn it off, thing is if i choose option 2, i only get 3G, while with option 3 i get 3G and H (probably H+ too if i were in the right place). Option 1 works fine, doesn't seem to stall, but 3G speed is crap in my network, that's why i wanted option 2.

Tried all three settings and I am getting about the same speeds with all three settings, 3600-4200 down and 1550-1620 up. So will try setting 1 to see if my connection carries on dropping out.
Thanks

Wat is the code for miui
Sent from my GT-I9100 using XDA Premium App

I actually tried this before on a few different radios and it didn't really work. The real problem I have is when I get in an elevator for a minute and get out shortly. It's not long enough in the elevator for the phone to say "No Signal" but it's still long enough for the data connection to hang and never bother hooking back up when I get off the elevator.
I'll try again though... will report back.

same here .... i tried the three options but problem persist

I have tried the codes above, including disabling dormancy but my internet still will not connect to the internet. Please help.

I'm with Optus (TPG) and I never really see H. It's either 3G, or H+.
I tried disabling H+ (option 2), and like the other guy now I only see 3G.
My Speedtest with only 3G was:
Down - 228.2kB/s
With H+ enabled (option 3), my Speedtest was:
Down - 482kB/s (but it's been as high as 1103.9kB/s in previous tests.
For now I'll just keep it as it is and put up with the occasional freezes. Hopefully it's fixed soon in a firmware release.

i cant seem to get the codes working.. after i dial *#301279# nothing happens, no menu nothing. tried on my wife's galaxy s 2 same thing.. is there an app to disable HSDPA?

\\Issue solved

Is this issue mainly due to the carrier?
I did not have this problem b4. Now I found that my phone might suffer from this.
Tried to disable the H+ or H & H+ at the same time, it seems the issue is still there.
I am on Vodafone Australia network. And I just raised this similar topic on Whirlpool, if you guys would like to discuss this network problem on an OZ forum, plz refer to the below

For me it's still the same, coming from KF2 to KG2. Will try KG3.

Any one with new modem firmware that 100% fixed the 3G drop/stuck connection(only see upload sign lit) bug? I am running KG1 modem(stock rom no root) and still experiencing this issue on ATT in Bloomington, Indiana USA.
I also realized S2 uses Infineon modem chip which is the same supplier for the iPhone3G that had the 3G slow down, drop call issue..
Could this issue be the chip at the end?? Why would Samsung taking forever to fix this critical flaw on I9100??

I'm on 3 UK. Had the cutout on KG1 and KG2. But it's definitely gone away in KG3.

I'm on Airtel India on KG3 and I still have the data stalling issue.
Seems to me like this issue surfaces more when I'm at home on wifi and then step out to data.
Trying out these service codes now to see if it helps to turn off high speed data.
It would make sense for Samsung to include these settings in the rom itself even for those without issues but want to save battery.
