The Edge symbol in my Galaxy S2 disappears when the signal is down.
It never reappear when the network signal get back. Even If i change all settings... tried disable/enable "Use packet Data" and other settings...
NO USE! It seemed to be serious and consistent bug.
Hi balavj, maybe a silly question, but are you sure that you are in an area well covered by edge gprs signal?

Signal drops inside a room... when i come out of a room... network signal regains... everything works... data connection symbol does not come back... this is the exact problem... only after reboot... it resolves
Ah I see... Never met these conditions with my phone here, so sorry I can't be of much help.

i am having a similar problem, seems to have happened quite recently for me as previously i had no real issues with it at all.
I keep having to reboot my phone to get a mobile network connection, otherwise the Mobile Network Status shows as connecting all the time...
Very strange
Try other modem, or shove the phone into airplane mode and back again should kick it back onto data.
I have the same problem here...
Tried KE4 (Original), KG7 and KH3 modems e nothing..
Tried many roms too, and nothing, the problem is on all of them...
Data on/off, Airplane mode on/off, nothing gets data working back, only reboot...
Ps.: ROMs tested: Lite'ning, Cognition, Exynos, KE4, KG7.
Kernels: Niphetamine, Jeffrey, Speedmod
SAme here
same here...
Is anyone still experiencing this?
I was having major issues with connectivity, data and calls. I got to the point where i could barely make or receive a call or connect to a mobile data network.
I tried numerous modems and firmware, including original O2 carrier branded firmware, generic firmware and custome ROMs. I found the problem replicating across them all.
I finally settled on Crsikelos ROM (V14) with KE7 modem, however i had previously done a full wipe install of my original O2 firmware (XWKDE i think) and tried a couple of different modems (KH3, KE2 and KE7).
I even tried removing my SD card as i am convinced my sd card is not compatible and is causing issues...
All of a sudden everything started to work again?? I put my SD card back in and left it in, no chance everything was still working. So then i flashed Criskelos Rom and made sure my modem was KE7, that was about a week ago and it's still all good.
TBH i think it may be something to do with O2's network being pants (rather than my SD card )....
Not sure this will help but i thought i'd post my experience for you...
Hope you get it fixed
i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.
Ok, first off I've searched many of the data connection issue threads out there but nothing seems to apply to my situation.
I'm having a problem where my data will disconnect whenever i receive/make a call and/or send/receive a text message. About 1-2min after the call has ended data will reconnect, if I toggle airplane mode data will reconnect a bit quicker.
I'm using a Bell Atrix, unlocked running Turl's CM9 from the below thread

I've had the phone for a year running the stock 2.2 then 2.3.4 then 2.3.6 and never had any problems until I unlocked the bootloader and installed CM9 a couple days ago.

You sure you're not in an EDGE/GPRS area? You can only have data during phone calls on 3G/HSPA+.
Edit: To verify this, go to Settings > About phone > Status and look at what it says for Mobile Network Type.

System settings/about phone/status/Mobile network type is :"HSPA:11"
I'm in a HSPA+ area, same location I've been using the phone since I bought it a year ago which is in the city core
ok, after a bit more trial and error I haven't been able to solve the problem but I have been able to narrow it down. As it turns out when GPS activates my connection will disconnect for the 1-2min as per above.
My workaround was just to disable GPS for the time being, but this isn't exactly a solution, if anyone has any advise it would be very much appreciated.

Remove multiple APNs. This happened with my old Desire Z. Whenever the GPS is on, data disconnects. Deleting unused APNs fixed this.
hmm, I've never deleted an APN before, if I do this will the network automatically reselect ones for me?
Don't delete everything, just delete what's not needed. The APN that's in use has a selected radiobutton at the right side. Leave that and the MMS one alone, delete the others.
I just deleted one of my two apns, then tested internet and a voice call which both still work, I turned GPS on and opened maps, I get the gps icon on the notification bar but it isn't blinking(also my network connection reset again), then I tried GPS test and again the gps icon at the top isn't blinking like it used to(it has the icon but it's hollow, i.e. no dot on the inside of it blinking) though my network connection didnt' reset this time at least.
I'm about ready to just chalk this up to CM9 on the Atrix just not working right because its unofficial and lacking proper drivers.
GPS icon in status bar does not blink when searching in ICS. You get a blank crosshair when it's searching for a signal, and a filled crosshair once it gets a lock.

ok so I tried turning gps on and running gps test, I let it go for 20min and it didn't pick up a single satellite(this is outside)
Try clearing agps data.

Thanks for the advise, I downloaded "GPS Status & Toolbox" from the market and used it to clear my A-GPS data, this seems to have solved the problem of my network disconnecting, however I'm still unable to get any satellites to show up in GPS test(yes GPS is turned on).
Any thoughts?
Hi,
I'm having problems with my XP
The problem is with the signal, in the status bar says 100% and it show the carrier name but I cant make a call or send SMS, I have to turn off the phone then turn on again to make it works
I have restored the phone two times without results, Android problem?? (I hope)
Is your sim working properly? Try it in another phone maybe? not a problem ive heard of before with this phone. This needs to be in the Q&A section btw
I take two screenshots with the signal state, the second screenshot was in the exact time when the signal drops
After like 30min, the signal is gone
Even the signal bar is empty
I will test the SIM in another phone
Do you have ICS and the latest firmware?
I have ICS 4.0.4
I will test the SIM in another phone
Here the OP resolved the issue replacing the SIM, I hope same for me
Hi all!
For about a week my International Samsung Galaxy S3 (i9300) have been experiencing network issues. At first I have full connection and after a while the network cuts off and my sim card disables (in the status bar the mobile data icon shows "no data sim") and then it switches back on and everything works.
This process happens constantly.
I have tried numerous solutions like flashing new ROM and trying to view logs.
It still shows the IMEI and I don't want to unnecessarily modify my EFS I've read that it can cause serious problems.
What is the problem and how can it be solved? Any help is most welcome and I will send logs and info if needed.
If the problem is already solved please show a link because I couldn't find anything that helps.
Thanks in advance!
I'm having a similar problem with my I9300 as well, the difference is that the network only gets cut off when I try to make a call, and then it comes back after a few seconds, and it doesn't show 'no data sim' it just stays with no connection (no bars). Messaging and 3G Data connection works fine.
I already tried to solve with several methods, the only one that I didn't try is to Odin flash back to stock, wich I don't really want to. I'm running cm-11-2016 at the moment.
Problem occurs with stock Rom. And I already tried CM11 and others ROMs.
When I turn on the phone, everything work great, both SIM registered, calls working, 3G connection. But after hours using (sometime 2 hours, sometime 6 hours aleatory) the signal indicator remain showing full signal, but is showed on "about" that network and phone number is unknown but still show type of signal (3G, Edge, UTMS). On both SIMs. Emergency calls only. Is like that could not read the SIMs card. And I can´t receive calls or make calls of connect on 3G. So, when I realize the problem I restart the phone and it come normal for hours. Airplane mode don´t fix, just restart.
I Already tried with stock BUBUANH1 (my phone is GT-i8552B) and BUBUANF1.
I believe that is a soft problem because my wife have same phone (both are after jul 14) and the problem occurs in both. I think very improbable to be hardware problem in two phones.
On my mind, this problem always occurred in the past, but I don´t had identified yet. The SIMs card were tested on gt6313 and worked well for 2 days.
I going crazy with this.
Could you tell what can fix it? i already searched for the modem.bin to this phone but cant find, anyway i think that if it was the problem it would never works.
First time when I used odin to flash, I chosed Phone instead PDA and flashed the stock tar file. The phone get a loop, but after I flashed using PDA the phone worked fine. Could this to be the cause? Could corrupted some thing?
