[Q] Cannot connect my 3g on HSDPA - AT&T Samsung Galaxy S II SGH-I777

Hi guys
Just got my S2 from USA and while using a 3g sim the data connection does not activate HSDPA (the H icon does not come out). On my Xperia Arc this comes with no problem.
Anything I am missing?
Am using my S2 outside USA.
Appreciate your help.

What does the phone display by the signal bar?
Alot may depend on the carrier you're using. Make sure the phone supports all the bands that the carrier uses.

Sounds like an APN issue. Copy the APN settings from your working device to your S2.
One of these links may be of help.

http://www.unlocked-dongle.co.uk/Se...-settings-for-mobile-broadband-operators.html

There is no icon on the bar. I have set up correctly the APN setting. Funny thing is that I can get connected on HSDPA on my other SE Xperia Arc and I get the H icon on this one.
The network option cannot be opened too.
I also tried the code *#301279# to change the HPA setting but to no avail.
Whats wrong?

Sound like you should talk to your carrier and see what they have to say.
In the meantime search online for known apn's for your carrier in your area.

Hi again.
As far as I understand my carrier does not deliver the band that my S2 requires to get connected on HSDPA mode.
Was wondering if rooting can be a solution? Am not really an expert but know the basics.
Any recpmendations/advise?
Thanks!

If it doesn't support the bands, it won't work.

Is there somewhere to see what the different signal icons look like? I used to get the little H on my Captivate (rooted and ROMd), but all I see on the S2 is the little green/red up/down arrows. I'm literally 100 feet from the cell tower and get blazing network speeds, but never see any H in the taskbar icon. Would be nice to see a reference of what the icons look like.

I think that if you decompile the framework-res.apk it contains the images, might be systemui, not completely sure

I was hoping for an easier way since "decompiling" is beyond my skill set.

You don't exactly have to "decompile," only extract using apk manager. Easy as pie instructions my signature (image replacement). Decompiling is for code editing. Extracting the apk gives you access to its images.

Hi Guys
Just to make it clear, my 3g does not connect data connection. Am still stuck with my S2 with no data connection while all other things work fine. What to do?
Need your HELP!
Thks

Did you check to make sure packet data is enabled in the Settings? I thought we already determined that your phone won't work on the bands available? Did you contact the network provider as you were told to do?

SOLVED!
Here is the case
My friend Sami just ticked the roaming case and voila the H+ icon poped up.
My understanding is that AT&T(with its factory OS) had blocked the network and by ticking roaming the s2 understand that by roaming you get the data connection. This might be another case.
Would be great if you guys can enlighten this situation.
Thks

[Q] counting mobile data doesnt work

hey folks,
I've been trying around to get a tool working which does count my internet stats.
I've already tried the following ones:
- netcounter
- 3g watchdog
- stats free
- traffic monitor
My device is a galaxy tab 10.1 p7500 (3G) latest stock firmware. rooted + cwm (no custom rom). Does someone else has a similar problem? It's counting Wifi data but not mobile ones. it's not displayed as zero but something like 68KB and I watched videos (connected to mobile data, yes! ) and run varios other applications with internet connection required such as mail, facebook, etc.
Thanks for your support
hey guys,
nobody else having this problem? It wouldn't matter that much at the moment but my internet flat is limited to 300MB HSDPA, afterwards GPRS/EDGE ... so I would like to have an overview about how much data I have used.
Would appreciate if anybody could help me out and let me know if I should test some stuff.
thx a lot
I have a unlimited plan, so i have not tried using counters, but i will try it for you.
EDIT: I tried 3G Watchdog and you are right, it doesn't work. So it seems that data counters are not compatible.
I have another problem, on my device it seems that the signal strength display in asu is stuck at 4. DBm seems to show the correct value but asu shows always 4. Can you please check what yours shows?
thanks for your reply.
same for me. dBm changes but asu shows always '4'.
on my DHD asu is changing nearly everytime. same for the galaxy tab 7" with android 2.3.3 of a colleague, asu is changing and also counters are working.
have you tried installing and using netcounter or something similar on your device?

Thanks for the info, i'm glad to hear that it's not a problem with my tab (or at least i'm not the only one with this problem). Hope it can be fixed with a future software update.
No i haven't tried any other data counter apps, but if 3g watchdog doesn't work, i'm sure none will work. This is either a problem with Honeycomb or Samsung modifications. I'm going to try and search and find out if any other people with other HC tablets have had such problems.
I have the verizon model and used 3g watchdog but now switched over to verizons app. Both worked for me and are pretty accurate when compared to my bill. Just sucks i dont have unlimited.
Tried 3gwatchdog and it was not counting... will email the dev.

that would be awesome to have a fix for that!
also found a german blog entry yesterday that it's a known problem but there is no fix yet
if someone can read german:
http://www.android-hilfe.de/1437639-post1.html
I searced a little, it seems these apps work on Xoom, so it can't be a Honeycomb problem. I found people are having problems only with European GT10.1 and GT10.1V, so it seems to be Samsung specific problem.
In 3G watchdog there is the option in settings to "Use pre-Froyo traffic counting interface"

already tried that, will not help!
would be really nice to have a fix for that because even there may be users which do not have a mobile data limit ... there may be some that have one
same here. cell data not counting. using traffic counter pro. maybe the incorrect interface have been selected. couldnt fi d the correct one yet.
Same here. Let me know if anyone has a option. It is not fun browsing in the dark (not knowing where my data plan is)
Will a custom ROM solve this maybe?

Seo fixed it over in the Galaxy Tab 10.1 V section.

same problem here with 3g monitoring on my P7510

how do i stop my 9100 from connecting to 3g

phone setup:
i9100
android ver 4.0.3
baseband i9100mugld3
cf rooted
This may sound like a crazy question but there are 2 locations i'm at a lot that have 0 to 1 bars of 3g and an edge tower right on top of them. Anyway for some reason the phone almost always wants to grab onto the 3g and it is a horrible connection for both voice and data. I have wireless there so i really don't care about data but dropping calls sucks. Is there an app, solution, workaround to forcing the phone onto the cel tower i want to use instead of letting it decide to do the wrong thing?
thanks
Have you tried just turning off mobile data in settings?

Settings > Wireless & Network > More > Mobile Network > Network mode > select GSM only and it will only use the gprs connection. If you dont want to use the GPRS connection then uncheck the " Use Packet Data Option ".
I've actually tried that while it disables data it doesn't force a switch on the tower. I guess my title & original question isn't quite right.
so now i guess how do i force my phone onto a different tower so i can actually get good service when i need it.
I just use the switchpro widget, since then i can turn on and off a lot of stuff from my homescreen.

Under mobile network settings, change it from auto mode to gsm only. I guess this is what you are looking for

actually i was just about to post the gsm/wcdma/auto to get it to switch over. However it does not always work sadly. I remember on an old moto (forget model) that i could actually choose a network tower, man i wish i could do that now

It perfectly works for me. If i set gsm only, it stays on edge and if i set wcdma only, it stays on H+ for me.
sorry should have been more specific again. it will go to edge but will often decide to pick a tower far away instead of a close one

How to use 3G data connection same time wifi?

I have a technical question ... you can use the 3G network for surfing the Internet and at the same time the wifi network to move files only?
Simply put no. Phones are not made to use 2 different wireless signals at once.
Bat cave One
The only way to use both is setting a Wi-FI access point on your phone. Still, you can't do things you want to: PC connects to smartphone just to get internet data.
No there is no way around it.

Do you even understand what your asking? Voice and data are 2 very different things. Data and call signals are handled by different process. The antenna are set to do one voice and one data. Think about it. Even dual sim card devices can only use one at a time.
Bat cave One
Yes I understand ... so it is not technically possible to manage wifi and 3g antenna at the same time because data can only handle one job at a time? I thought the wifi module and the module 3g were managed separately...
This is an android software limitations?
When you use the wifi 3g module is put into the off state to save battery, works only the incall module. When you disable the wifi 3g module change the status to up. About your question no, it's impossible to use wifi and 3g at the same time to make 2 different operation

thanks for the reply. just in my office I have a wifi router with no internet connection, are connected with the phone to surf the intranet. so I would keep the connection 3g to receive notifications from whattsup or other ... every time without having to turn off and on the wifi. It does not seem like a stupid question.
This is not directly related to your problem but using wifi and mobile data at the same time seems to be possible: http://forum.xda-developers.com/showthread.php?t=1667025
Tank you, i see that... But you can only download a file....
I read of a change made to the file system / framework / services.jar
But i don't know if it work....

That's incorrect. Android phones can use multiple wireless signals at once (wifi, cell, mobile data, bluetooth, nfc). And they can have multiple network interfaces up at the same time just like any linux box can. It just happens that the network manager turns of mobile data when you turn on wifi, but that's on purpose (to save you battery/cost), and not because the phone isn't capable of it.
Not sure why you say with such authority there's no way around it. If you don't know the answer to something for sure, better don't give a wrong answer.
There's even an app on the play store that can loadbalance a download over wifi and mobile data at the same time:

I say this from past experience that the WiFi antenna could not get a signal at the same time as the data antenna.
Now while this may have changed. I will look into it myself before I pay much heed to it as anything more then smoke and mirrors.

[Q] 4g and wifi icon after 4.4

I now have a 4g and wifi icon present on the notification bar when connected to wifi, not just a wifi icon, any one else with this problem?
Not a "problem", just a change they made. Even with mobile data off you will still have the icon letting you know there is data coverage available. Don't know why they changed it, but thats what they do lol

Change, for the sake of change. I can almost hear the software engineers: "Well, there's really nothing wrong with this, but if we change it, people will think it's a "NEW AND IMPROVED" feature!
I have 2 S4. On one the 4g stays grayed when WiFi is running. My other S4 has the 4g on while WiFi is on. In each case, neither shows any 4g activity (arrows moving) with WiFi on. This is rather odd since both are setup the same with regards to WiFi and mobile data.
Update: by turning off Caller Name ID app, I have both of my S4 acting in the same way (4g consistently grayed out when WiFi on). Why the app affects the 4g icon is beyond me.

Mobile Data - No LTE on ROMs

Hi all,
Thanks for taking a moment to see if you can help me out! I haven't been on the forum in a long time as I haven't had my Android devices going, but I'm back! (Older, and I wish wiser!)
I am flashing a few different custom roms to my SPG771 (karin), but even though it's recognizing the SIM card, the network is appearing, and the APN details look correct, I don't get any mobile network data transfer when off WiFi, I can't even get it to show 4G/LTE in the top bar beside the data strength bar.
Anyone experiencing anything similar with regards to cellular data on custom roms?
Thanks in advance for your help!
I should note, the data is working perfectly fine on the stock images from Sony, either using the nordic general or the UK custom.
