Yesterday i put my mobile in the airplane mode and slept. Today morning when i switched back to Normal mode, I got the message "No Network Coverage.". But when i switched to settings and selected the network operator manually, i get vodafone for few minutes and again it reverts back to "No Network Coverage." condition.

Hi
One week ago I moved my personal phone number to a roaming phone operator, called simyo (belongs to KPN). Several times per day when I try to access internet (I use push mail, always on gtalk, etc) cant do it. It seems is connected the internet. The coverage shows 3G and the uplink arrow shows activity. Of course I ve marked the options "Use on roaming network". I need to reset the device or turn on/off airplane mode. I had a similar problem with windows mobile time ago in other samsung device. Never had this problem with other phone operator or using the roaming operator (simyo) with other android device. Any idea?
ive been using the phone for a few weeks now and it was fine until today, i cant connect to the internet via edge . ive tweaked with all the settings but nothing seems to work. everything else is fine . ie i can make calls and send text's but i cant connect to the internet. i checked under the status and it shows the mobile network state is disconnected. i have no clue as to wat this is since im new to android.
pls help!
Have you turned MOBILE DATA off via the power on/off menu .
jje
ive checked that too.
Go to Settings- Wireless and Network- Mobile Networks- Access Point Names and see if the APN is ticked or not or the correct APN is ticked.
everything is back to normal again,it connected to the internet, by itself . must be a random bug in the os
problem solved. peace
I have experienced the same thing with my phone, except that it shows "activated". After a while it just started working again.
I've had the phone for a couple of months now and everything has worked fine till now, a little bugs here and there but no issues. A few weeks back (on android 2.3.3) I was unable to make or receive calls, but surprisingly was able to make text messages. I tried everything, turning flight mode on/off; the phone on/off; etc. I was on the verge of contacting Samsung but then suddenly the thing started working once I came back home from the office.
There has been no problems till then but today suddenly (now on android 2.3.6) the outgoing calls no longer work, same for outgoing text message; but I still get incoming calls and messages.
Just to be sure that this wasn't a SIM or service issue, I tried changing SIM's (different SIM did not work on the phone) and used my SIM on different phone (where it worked).
Also 3G doesn't work as well, but connection here is spotty so I wouldn't trust that. The only message I see different on the 'About Phone' tab is 'Mobile State-Disconnected'. I have full signal strength and all that.
My thoughts are that it was, or rather is a phone specific issue and would appreciate someone else's thoughts on the matter. As to my problem I assume it will sort itself out in a little while.
FYI: Samsung Galaxy S2; Android 2.3.6; NOT rooted; Indian version; On Airtel Mobile Network.
Mobile network state disconnected.
Hi guys, I have the same problem with my network connection also my 3g does not work anymore, I`m play with some secret codes like a ##72786# on my epic 4g touch sprint phone flashed to metro pcs and now I have no 3G service. In the setting menu under network status say Sprint. How can I get my 3g back?. The mobile net. 3G is on and the wifi is off. I need to change the network to metro pcs in the status setting and how can do that? Thanks for your help and sorry for my bad English.
i have installed MiniCM7-2.0.7 in my X-10 MINI about 1 month ago. Till last night it was working fine.
But last night i got a problem which still persists. I am not able to get the Network signal bars in my phone and due to which i am not able to connect the call or do the internet. But the phone is showing the carrier name in notification bar while pulling down it.
However, i Have tried installing the rom again before complete wipe-up but the problem persists.
please have a solution!
Try this way.. Go to settings->wireless settings->mobile network->network operator ..and then select the operator manually.. I guess it should work..!!
Gintonic.SE + zombie-pack kernel by slade ..
tried dial *#*#4636#*#*
select "phone information", you can view every information regarding your radio quality, the signal strength, network band, etc.
press menu button and "select radio band", test it one by one, if you unsure select "automatic"
if everything failed, the problem might be your simcard or your network operator setting, you should contact your network operator customer service.
(i doubt it's your phone hardware/software problem, unless you just force unlocked bootloader that your phone didn't meet the criteria to be unlock)
not solved the problem!
anyone..........
Standard htc one m9 with ATT. not rooted and up-to-date with android 5.1.
I went to domincan republic for 2 weeks and I purchased the att passport package. Once I was there, I searched for networks and used the Claro 4g network over there the whole time. Once I return to the US, the phone refuses to automatically connect to the ATT network and continues to search for the claro network.
What Ive done so far.
-muliple restarts
-remove sim
-When I go into network operators, both options "search networks" and "select automatically" are greyed out and I cant select them
-When the phone is restarted, the "network operators" screen pops up and lists ATT, sprint and verizon. But when I try select any of them, i get an error message saying "operation failed"
-ive reset the APN to default multiple times
Heres where it gets weird. I popped out the sim and put it into my htc one m7 and the phone works fine and connects to the att network. I can make calls and use the web. Once I place the sim back into the M9, it will connect to the att 4g network briefly. I can make a call to my voicemail very quickly once i gain service and it will work and I can browse the web during the call. Once the phone call hangs up, the connectivity bars slowly go down until i lose service and the a msg pops up saying "Claro Network unavailable". I can repeat this cycle over and over.
I tried placing the sim card back in and resetting the APN right away a bunch of times. This actually allowed me to stay connected to the ATT network for a few days. HOWEVER, I had to restart the phone and I was back to square one.
ATT was no help and they basically told me to hard reset the phone. WTF.
Any advice?
anyone?
Hi everyone, I recently bought an used S8+ (G955F). The seller didn't say it had any problems. I happily went home, inserted my sim card and turned on the phone. Entered the pin code. Then it all went downhill really fast. I will list my observations here (tried with multiple sim cards from different carriers, same stuff every time):
Signal - 1/4 bars when out of the city, 4/4 when in the city.
When sim is inserted and the phone is turned on pin code is required.
When trying to call anyone, Not registered on network error is shown.
When trying to send an sms to anyone, "Currently unable to send your message . It will be sent when the service becomes available" error is shown.
When pressing Select network operator automatically in network settings, "Unable to connect. Try later" error is shown.
When pressing Select manually, "Error while searching for networks" error is shown.
Internet not working as well.
At first I thought it was a demo phone, checked IMEI and baseband version - they were there, so I think it isn't a demo phone.
Could you guys help me out in troubleshooting this device? Could that be a software or hardware problem? Any help will be appreciated <3
Some things I forgot to mention
MM#6 error is present.
However, I checked imei.info and imei24, the phone is not blacklisted on both. Also it shows as unlocked. What is going on
