Hi Parul,
Could you please provide us log with ril debugger enabled? And capture the log by "adb logcat -b radio -b main -v time|  (time parameter is helpful for us, please don't forget it:p ). Thank you.

According to the line |04-07 18:34:32.500 I/Gecko   (  193): -*- DataConnectionHandler[0]: No network interface for default data.|  I reason that gecko hasn't received apn setting from gaia, but as I couldn't see any messages related to "apn",  more messages are needed to help.

Hi Parul,
Please help capture the log again. And please record log messages starting from booting, thank you.

Attached adb logcat with ril-related debug flags turned on. Repeated steps in Comment 4. Magic happened. Functionality now working as expected. Bug could not be reproduced.

== Steps to enable debug flags of ril, mms, network in runtime ==
Go to https://github.com/bevis-tseng/Debug_Tools and download script "enable_debug_flags.sh".
adb root
chmod +x enable_debug_flags.sh
./enable_debug_flags.sh
Wait for B2G restarting complete.

== Steps to capture the packets in the devices ==
Go to https://github.com/bevis-tseng/Debug_Tools and download binary "tcpdump".
Install attached tcpdump command into test device:
adb remount; adb push tcpdump system/bin/;adb shell chmod 777 /system/bin/tcpdump
Start capturing tcpdump:
adb shell tcpdump -i any -p -s 0 -w /data/capture.pcap

error: only position independent executables (PIE) are supported.

Q: What does the error "error: only position independent executables (PIE) are supported" mean?
A: Android 5.0 brought the requirement that only executables compiled with the -fPIE flag. These packages were compiled for Android 4.4 and earlier, so they won't work on 5.0.
