General :: Android 4.0.4 - GPRS Not Working On Any Network
Aug 16, 2013
I own an android dual sim phone running on Android 4.0.4
My GPRS was working fine but I dont use it alot since I have WiFi. Now after sometime I wish to use GPRS but its not working.
I have tried to reset the Access Point Settings and ensured that the settings are correct by matching them with a frd's phone. Everything looks fine but the GPRS is not working. What to do?
I have tested it on two different networks to see if the issue is at my network's end but the GPRS didn't work on both.

Just installed Galaxo 1.6.3.4, everything works great, except that gprs/edge capabilities seem to be switched off? They used to work before the root. I can use wifi, but cannot get any data traffic outside wifi areas.

Anyone else here using Docomo service in India? In the last week or so, my GPRS has been spotty. Actually, it's mostly not working at all, but will sometimes be up for an hour or so. In perhaps related news, I've also been receiving empty messages from 52236 via SMS.

I just got my Galaxy S4 today, and decided to turn off Wi-Fi so I can see if 3G works. I have a bunch of bars, but every time i try to use something that requires an internet connection, the phone says im not connected. I dont even see a menu to turn on 4g and 3g like my Evo 3D had.

I'm a SGS2 owner on T-Mobile and a university student. Yesterday morning my phone anomylously deregistered itself from my network, displaying the error message "Not registered on network" whenever I attmpted to make a call.
I phoned Samsung and T-Mobile and resolved the issue by a 'Network Refresh' and manually registering the phone to T-Mobile. I registered manually and had the phone working hours before I got the text from my NSP telling me that I had recieved a network refresh. About which time I noticed that my 3G was not connecting, and has yet to establish a connection today.

I am trying to do 2 things with monkey
1. Execute a script with a command like
adb shell monkey -p MY_PACKAGE --setup scriptfile -f /sdcard/ mon_script1.txt 1
where mon_script.txt contains a few touch commands. After I execute this, I see nothing happening on the screen. It even does not give me the "Number of events injected message". I have verified that my touch co-ordinates fall over actual UI elements.
This is the script file I am using
tap 79 29 tap 100 100 tap 200 200 tap 300 300 quit
2. Execute Monkey Network control to type commands individually. I start up monkey to listen to a port and use PuTTY to send commands. I get "OK" return messages, but nothing happens on the screen.
Whenever I use monkey in the random mode, I see interaction on the screen. But I need to get one of the above 2 methods to work. I have seen the sources of monkey and nothing seems to be wrong. Has anyone used monkey in the above described way? If so, please tell me what I am doing wrong.

I have observed that the Smartphones (particularly Android) do not perform as well as the computers when performance is compared on GPRS / EDGE.
I have tested streaming videos on while on GPRS / EDGE (not 3G or 4G) and observed that the smartphone gives up saying connection problem. When I stream the same videos with the same GPRS / EDGE connection through a USB Dongle on a computer(with same SIM Card inserted which was used for testing on Smartphone), the Computer performs better and is able to stream the Videos.
I request the experts to explain why this happens. The SIM and its location are the same and the speed received from it is also the same. Then why does the computer able to play it while the smartphone gives up saying connection problem.
I would like to clarify here that the GPRS / EDGE works alright on surfing websites etc. while the problem is only in streaming. I have tested this on various phones of Samsung / HTC / Motorola so the question of a particular phone having some problem does not arise.

I'm not familiar at all with the differences in the networks in terms of CDMA, GSM, etc. I just read a news brief about the DROID possibly going to ATT at some point and the person writing it said something to the effect of "for those not wanting to be tied to the verizon's CDMA network." I thought verizon had the best network. I realize that in the past Verizon has crippled phones, but not sure if that has anything to do with what he was referring to, doesn't sound like he was talking about that.

My Mobile Network isn't working. Period. No it's not location, I get 5 bars of 3g in my room all the time. I'm able to go on WiFi. My 3g just all of a sudden stopped connecting.It says: "Stand by for connecting to mobile network". Not to mention the incorrect grammar, but what the hell? This is the reason I bought a smart phone. It happened 10 hours after the update.In New York City, was working fine at work earlier. I can still get text's/calls.Anyone else have a similar problem?

All I want to do is from time to time check my mails. For this, I want to activate the mobile network connection (3G) manually for a short period of time, and then de-activate it again.
The problem is that enabling the "mobile network" checkbox after my phone has been idle for some time, doesn't actually activate the 3G connection. (no "H" or "G" icon in the notification bar)
So when I open the mail app it complains with a "connection failed" message.
Even better would be if I could find a way to have my mails automatically checked whenever the connection is activated ...
Other than that I'm very happy with the phone.

I have been looking at the ConnectivityManager class documented at http://developer.android.com/reference/android/net/ConnectivityManage... .
I would like to know if an Android application can open a network connection (socket) on a specified network interface [on a device supporting multiple network interface types WiFi, Cellular, WiMax etc] ? I am looking for the capability for an application to open a socket on a given type of network for example over WiFi network or over 3G Cellular Data network.
If this is possible in Android, how would I code this requirement within the API Framework ? The ConnectivityManager enables an application to learn about available network connections and currently categorises them as either TYPE_WIFI or TYPE_MOBILE.
There is a member function in the ConnectivityManager class called requestRouteToHost(int,int) [url] which "Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful." Sounds like this would install an IP routing table entry to reach a given host via a specified network interface type (WiFi or Mobile). After calling this would it be sufficient for an application to open a socket and connect to the desired destination address ?
Or perhaps the application needs to bind() a socket to a local address of a network interface of the desired type (WiFi or Mobile) Or by setting a socket-level socket option of SO_DONTROUTE ?

I have recently upgraded to the HTC DESIRE on o2, So far all I have seen is the "G" = GPRS, so far I have not seen 3G, E, or the HDPSA or what ever it is :-). Does o2 support anything else but "G" on this handset etc etc, or is my phone faulty ? I live in the UK and so far today I cant even use my internet - O2 have said there are having issues with 3G but didnt say where in the UK or maybe this is Nation Wide ?

I'm a android application developer novice.
I'm try to get latitude and longitude value via android.Location class, but sometime my system can't to get The correct value is lat: 0.00 and lng: 0.00, Perhaps It's return incorrect value because Android detect by GPS only.
Now, I know that location value can detect by GPRS/WIFI, and how do I get It ?

I am currently in China and therefor run a VPN on my PC to connect to the outside world, I would also like to run the same VPN (PPTP) on my android. I can connect via VPN if I am using WiFi but when I try to connect over GPRS/Edge I can't get any connectivity. All web pages load with the standard "web page not available" and apps, eg. the market place, won't connect either. I would have thought that if it was a carrier issue (CMCC) I wouldn't be able to connect to the VPN in the first place. So is this a Android issue, a setup issue or a carrier issue? And can you actuality run a VPN over GPRS om Android?

Is there any app or some thing like that, that I could use it to turn on mobile Internet 2G (EDGE/GPRS) or 3G (UMTS/HSDPA). I now turn off/on mobile Internet with Toggle Data widget, that changes APN type to "-" so it can't work. I am asking this because i use GPS tracker app. And I can turn it on with sms with code: "gps_tracker_start But if i want to report my location I need to be connected to Internet. So I could see my android phone even if it is not connected to internee. So is there any option to turn on mobile Internet remotely?

I just got an x10(android 1.6) , it seems like d phone can automatically access network/gprs whenever it feels like, this may cause a huge bill on me n also drain all battery power within d day, unlike older phone(not that old), gprs will be in use when needed n shutdown when not needed.
The only way to stop all this auto 3G downloading/uploading is to manually disable all the mms feature in the mobile networks or kill all task(kill task appilcation). And if i wanted to use those gprs, again i have to manually turn on all these setting, whereby traditional handphone need not do all these , which i find it more convinient unless subscriber has all the free DATA given.
Hopefully the os/software can be upgraded better to understand a user needs whenever needed and not automatically downloaded data as if noone bizness.
