3G network

First, as you can assume, i have the HTC Hero...since i was not satisfied with the 1.5 version ( android ) i updated it to 2.1 ( Eclair version )..now the problem is that when i add the APN settings, it starts the 3G network and i don't have any option to "close" it...on the 1.5 version i had a the Wifi, Bluetooth and i think Data connection, but now only the Wifi, Bluetooth... so in a summary, i can open and close the wifi and bluetooth but i can't regulate the 3G network, when i set it, it starts and there is no way to turn it off...
So does anyone has an idea how to solve this?
Thanks in advance

How about when you hold the power button, do you get the "Mobile Network" option to select there?

No, just the silent option, airplane, reboot or turn off...
The irony is that when i turn Wifi on, the 3G also turns on...but when i close the wifi the 3G still works...

It seems i have the Nexus One software on my Hero, i received a mail from google, welcome to the world of Nexus one... OMG...

Maybe ask in that thread.
Or flash a diff ROM and see if you still have the same issue.

Im using MCR3.2. (Link in my signature). Fast and stable,... No issues whatsoever. But it is still only an Android 1.5 ROM. I'm planning on adding the 768mhz overclock kernal to it tonight, hopefully will fly like a Legend then.

Ooops,... Sorry

You not the only one with this puzzling problem wkulen! Same rom as you, and it seems I can't close 3g even with that APNdroid is set to be off! It looks like it still using data from 3g - hope not otherwise it could be a costly mistake!

i've got the opposite problem...
ROM: current official...
My 3g or data internet connection sometimes doesn't turn on when I switch off the wifi. But it happens most of the time, but not all the time. What I normally do everytime is to go to Settings/Wireless controls/Mobile network settings/Network operators - and I "select automatically". Then my network data kicks back in. It's a hassle but I don't know what else to do.

Help! My SGS2 is dropping calls

My phone is dropping every single call lasting more then 20 40 seconds. It suddenly turn off all receivers and the call of course ends at that point.
Is there any fix to this?

Try this modem, works for me, before i had problems with handovers from GSM - 3G

First try to set your wireless network to gsm only..try to make the same calls..if you have no more call drop issue...get your phone replaced.
I am one of the unlucky ones who are having serious issues when gsm/wcdma mode is selected.. basically when the signal strength changes and the phone is trying to lock to another cell..it simply disconnects and resets the radio..actually you can try running LogCat and see...just before your radio resets the is a process of usb host getting installed/disconnected and gets blacklisted..something like that.
If you are not having these symptoms than it is some other issue...try it out and see.

Normally cell phone providers have soft handoff where the signal strength decreases and the strength from other cell site increases and that site starts processing the call hard handoff happens between gsm and cdms probiders normally seen in roaming calls...by any chance are you in an area where reception is weak

Mine was dropping every call if it lasted long enough. Tried to flas with the newest ROM from Samfirmware, but no improvement. Tried to flas the modem in post #2. Hopefully this will help.
Seems to turn off all recievers both Wifi, 3g, cell. Showing only a " Ø "sign where reception is.

ICS issue with modem

Hello,
I installed Sam's ICS RC2 for SGS and it's amazing, however, wifi works but I can't connect to network, the phone fails to connect. I have tried flashing other modem (XXJVT i reckon) without any result.
Any ideas?
Thanks.

having same issue but with another build of ICS

I do not see how a new modem will affect WiFi. AFAIK, the wifi stuff is built into the kernel.
Does this happen for any wifi network? Have you tried connecting to some other network?
If nothing connects, you might be looking at a factory reset and data wipe

Data enabled setting is for data transfer over GPRS/EDGE/3G networks, not related to WiFi at all!

I agree. I may have misunderstood the question. The OP said that wifi works and he can't connect to network. I understood that to be the mobile network seeing that he is talking about modems.
Wifi has nothing to do with modems.

Aah! Now that I read it again... I think I understand what you understood. The OP is a bit ambiguous in that case

Perhaps it is an issue with the pin unlocking code. Can you put the sim in another phone, remove the SIM lock pin, then try it back in the Galaxy. It might narrow down the issue for the devs.

I have try ics on miui galnet! It uses JV5 as modem! My signal is the best! I have try more modem but with ics signal is very good! I do not test consume! If you want, you can install other modem! I suggest JPG modem! It works fine and less consume of battery!
My operator is H3g italy!
You can find you modem only trying it!
You measure performance signal (3g, 2g, wi-fi, gps) through apps market about signal and consume with time elapsed.

i'm using the zsjpg modem with ICS (for cyanogen kernels). very good modem.
edit: if the cwm installation doesn't work, try the updated version (like the new thunderbolt scripts).
edit2: it seems like the zip doesn't work anymore for new ICS builds :/

3G works like on-demand

Hi All,
I have been having problems with my S3 for some time now.
HSDPA. Sometimes it works and sometimes it does not. It works as if it was set up to work on demand.
Where could it be set up like that? I have checked every menu and cannot find anything.
Help much appreciated.

I don't understand, do you mean it keeps switching between 3g and H when you ate using it and not using it?

HSDPA works and in a few seconds stops. No data at all. Then HSDPA works again for a few seconds and so on. No pattern or anything. I tried to keep it running by keeping Skype work, but it would disconnect from data completely again. It is connected to HSDPA network and I can make calls over that, but no data.

Sounds like your being ping-pong'ed between antennas.
Usually flashing a eastern modem (I can recommend the ZN... ones) should fix it since they are optimized for large cities which have this issue.
Also, having a proxy server configured in the APN settings may cause this issue if it's overloaded and causes connection resets.
If you have one configured, write down the settings(in case you need it ) and try removing it.

Some good ideas.
Heading to the modem collection thread.
No proxy in APN.
An interesting thing is, that I went to another city a few hundred km away and everything was ok, so I thought it was the phone and it started working again. I am back in my area and it is happening again. The only thing is, no one else is having these porblems, even people using S3.
EDIT:Just fashed ZNLH3 using CWM and will start testing. Right after starting the phone, there is no data active.
EDIT2: I forgot to mention, that when I switch to GSM only mode, EDGE works just fin, no disconnects at all.

Try fast dormancy apps from play store and disable it.
The switching between hsdp and 3g is not a problem. It is a technology to preserve your data usage when you are not using.

There is no problem switching between 3g and H, there is a problem with switching between HSDPA and NOTHING.
ZN modems did not work.
Will try fast dormancy, the setting was not available in the ZN modem under *#9900#. Will try LH1 and Pay Store.
EDIT: FD switch installed and FD disabled. Will do some testing and report back. Working on LH1 modem now.
If you still have suggestions, they are more than welcome.

I am having exactly the same problem on 3UK... the data connection just stops working for no apparent reason

For another test, download a terminal emulator app from play store and then ping google.com or any other site in a loop ... See if you get breaks ...
Keep phone still ... Then try same with moving it around your house ...

Must be something with the phone, as I disabled FD and data connecition is gone again.

My problem is that my data does not work when on 3G but it works when on H+.

Position has not effect, it happens wherever I am.
I will try with ping and see.
EDIT: PIng seems to make the connection persist. Will keep it running and see.

Been running ping for over an hour now and no data cutoffs. Means there is something that keeps disconnecting me.
How do I find out what and fix that?
To answer my own question:
I instaled DLI1 last night and so far in almost an hour not a single data blackout!

I was wrong blackouts still happen
Using DLI1 and FD switch, it now works much better, but there are still blackouts.
I will look for the GSM Monitor software and see if that can help me identify the problem..

problem is your location ur phone is jumping between 2 bad signals/towers and one of those towers does not have 3g on it only 2g
I say this because I have same problem at home. certain areas of house amazing 3g reception others .ir does not work and ye so .ir flicks between them and I often eexperience "blackout" . .signal says on H but no data throughput.
try downloading gsm monitor from play store will show u how string signal is and which tower it .
hope this helps
really hope u find a fix ( I've just accepted it )

I'm pretty sure that disabling fast dormancy will fix this. I've seen people with that problem before and was fixed instantly. Search the forum for the fix. There is a file you download to insert that will fix it.

Did you try enabling wcdma only mode? Settings-more settings-mobile networks-network mode.
That might work by forcing it to stay on 3g/h+

Of course, I have had it set up like that since the beginning.
Remember that my problem is not with constant switching between HSDPA and EDGe, but with switching from HSDPA to nothing.

GT i9505 weird service problem

Ever since I got this phone i never once get any service i thought maybe the bored was done for but today I went into the town area and was surprised to see 3 to 4 signal bars on it i tried making a call and it worked, even sent an text message and it worked, funny thing now when I came back home I then again have no service bars whatsoever so I went back into town to see if I would get back signal again and i did..... Went back home for the second time and now no signal again, anyone know what might be the problem, I'm on slim rom 4.4.2 baseband XXUFNA5

Do you have a bad signal inside your home? Signal inside a house can never be guaranteed as there are many factors that affect signal strength - especially indoors.

I have an S3 and I get very good signal on that at home it's just something wrong with the S4 but i just don't know what... I get not one bar on it any else where, only when I go into town area

when you connect downtown, do you know what network you are (2G, 3G, LTE)?
It might be that near your home you only have (for example) 2G, but your phone is set to search for 3G only.

So I tried different modems and I flashed stock rom twice and still no luck, any other suggestions please

I take it u can't read or u don't have a very good sense of humor eh?

We might have a very similar issue, I also don't have a solution (yet).
My phone does not connect to 3G, only 2G and LTE.
To check if you are in the same situation:
*#2263#
then play a little with the settings there... (for example try 3G only).
see if you get any positive things out of this.
(as a note: in some of the options I can connect to 3G, BUT I cannot make or receive any calls - internet is working though). You can choose a single option only (try each 2G, 3G, LTE and see what happens). However, I strongly suggest to keep a combination of 2, see the note above).

Yes, its possible. Use Odin 3.0.7 or 3.0.9 and flash DBT (German) or BTU (UK) ROM. After flashing boot it up (but don't set up) and do hard reset either from Menu or use key combos.

The answer is in your picture of being in town. You are only connecting on EDGE. So my guess would be that you have bad coverage in that area, ie weak signal and no LTE.
Check your providers coverage map.
