Hi all, I'm a noob to this site and desperately need help.
I've just purchased a S4 I9505 second hand (IMEI checked and not blocked). I'm on the UK 3 network and after putting my sim card in I get signal and reception until the phone goes to sleep (times out) then when I wake it up my reception disappears, with no signal bars, no service and not registered (3) on network. The only way to get reception back is by:
Enabling flight mode then disabling flight mode
Re-enabling my network under "Mobile networks" ---------- > "Network operators"
Re-booting the device
I've already done a "hard" reset in recovery mode and verified the APN and that doesn't help. I've spoken to my network provider whom tell me its a common problem with the S4 which doesn't leave me with any help.
I desperately need your help people.

Hi experts,
Very frustrated with the SGS phone GT-I9000 I bought a week ago. I keep getting "Data network not available" while trying to make merely voice call (in area with poor signal).
However, I have no problem making call using old Nokia phone with the same SIM card.
The GT-I9000 was upgraded to Froyo 2.2 (DXJPE) lately.
Anyone encountered similar issues? What's wrong with this Android phone, modem issue?
Regards,
Void
That new i would return to seller and get them to check phone under warranty .
jje
i got the same problem after upgrading to froyo, im from Panama, but i flashed my device following some UK guide, so i flashed it with another CSC, so if you did so, we both lose our network settings, so you have to set up the APN manually.(thats what i read) but i did so and i still cant make calls nor receive 3G
It happens on EDGE. Make sure you've selected the network to operate in WCDMA only..
Switch the Wireless and network -> Mobile network settings -> Network mode to "GSM only" or "WCMDA only" but doesn't resolve the issue.
However, I notice when the problem occurred, the Setting->About phone -> Network showing "Unknown" but the Signal strength seem to be OK, fluctuating between -87 dBm 13 asu (with 4-bar) and -111 dBm 1 asu (2-bar )
Probably, SGS transceiver/modem is not as good as Nokia E71.
Anyway, I guess I can only use this "smart" phone in city area.
in my case the problem was the orange phone card. i have changed it.
Hello everyone!
I bought Atrix recently and since purchase it was with Android 2.3.4 and the only issue I had was two random reboots and few "network connections errors" messages and brief lost of my Data Connection over 3G network. But yesterday I had that same message and since then my 3G is gone... Nothing helped - reboot, deleting APS and restoring'em, pulling SIM...
When I go to Settings → About phone → Status, Moble network state is "Disconnected".
I don't wanna root my phone in order to reflash custom or stock rom.
Can someone give me an advice or share solution if he has experienced same issue.
Cheers and Thanks in advance!
O.K. I fixed it. just dialed *#*#4636#*#* to go check DNS but I noticed that "set preferred network type" was set to "Unknown" so I put it back to WCDMA only.
hello all
My phone will lose the network signal and respond to any attempt to make a call with 'No Network Available' trying serch network "Error Seach"..
I have found that turning on Aeroplane Mode, then turning this off again wakes the phone up and it finds my home network (Telcel/mexico) immediately or sometimes does not return need extract sim or reboot.
another problem is that when I make a call not heard anything
Problem software?
Is there a bug in the latest release that others have noticed, or is it the view of the experts here that the phone has a defect?
I´m trying chagen option dial pad *#*#4636#*#* an "phone information" find and change "preferred network type" to "LTE/GSM/CDMA auto (PRL)" and reboot phone after changes not save
Thanks,
Sorry google translade
Help!Help!Help!Help!
Just posting this in case somebody has some ideas. I've had a MetroPCS LG Leon LTE (MS345) for over a year without problems, but now it started losing its mobile connection sporadically, for a few minutes or a few hours, as if there was no SIM in the phone.
Symptoms:
The 4G indicator disappears from the notification bar (signal strength indicator shows good signal).
The lock screen says "Searchng..."
Calls fail with the "Emergency Calls Only" message
SMS won't send
I get a "Service Unavailable" error when I choose Settings/Call/Additional Settings
WiFi is unaffected (and WiFi calling seems to work, though it has always been hit or miss)
Things I've already tried:
Checked relevant settings, APNs, etc
Checked the contacts on the SIM socket, all looks good.
Reset Phone to factory defaults
Replaced SIM (MetroPCS did this for free)
New phones are relatively cheap, but I don't have a burning desire to upgrade, so I'm hoping for another option.
I'm having this same problem. I left for an area with no service and came back to an area with service to find that my phone will constantly state Emergency Calls Only and no service. Does anyone have any suggestions?
Hello
I have buy St i959 unlocked
I used it for month with 4.4.2
But when I updated it to lollipop 5.0.1
Signal (cdm)) stopped and back, menu button stop also
I tried to solve this.
The signal when I restart phone appears for 30 seconds
and a message comes saying (refreshing uim card data)
and signal then disappeared.
I tried to inter sim uim setting but I can't because the setting page can't be interred (it say no sim uim card)
What I can do
Restart phone and quickly go to sim setting and sllect network manually
Can't search cdma it automatically
But I sheached GSM in this slot (3 networks avillabe)
as always signal listed
But the page setting still and I choose this time searching cdma networks
In this point the signal comebacks
And I can dial send messages
..
What happens. I will wait days to see
But back, menu buttons don't work
UPDATE:
after restarting phone or use airplane mode
the network lost again
And i must repeat the search as explained above.
Oooooooooooopppp
