1. Tips to resolve call-dropping:
Disable All call forwarding by typing ##002# on your keypad,
then tapping the call button. On confirmation you will see Message 'MMI code started'.
Then , you will see another message- 'Call forwarding
All
Erasure was successful'
This should enable outgoing calls & stop call-dropping.
One main reason for Call-dropping is that someone has hacked into your phone & your outgoing calls are landing at hacker’s phone number/end. Hacker may've done it to get info on you.
Ensure also that your network is connected properly by using following steps:
Go to settings ->Connections -> Mobile networks -> enable 'VoLTE calls', tap on 'Network mode' & enable 'LTE/3G/2G (autoconn..)' & not the '3/2G (autoconn..) if your palmtop/handset has these network mode options as is the case with Samsung M30 which is a 4G palmtop/handset. Enable the correct option as per you SIM.
