I had installed a new security patch of 1 April 2020. Immediately after my Idea Postpaid sim (now automatically migrated to vodafone because of idea vodafone collaboration) lost the network.
I have tried following things,
I tried resetting the factory settings - didn't worked.
Tried another idea (Prepaid) sim in my phone - Worked
Tried putting my postpaid sim in another (samsung) phone - worked
Tried changin sim to another slot - didn't worked,another sim (jio) is working perfectly in both the slots.
Tried setting idea sim as data sim with network type 4G
Tried to play with #*#4636#*# - didn't worked
please help me to solve this issue
