Firmware/APP Version: PPR1.180610.009WW
Frequency of Occurrence: This is the second time it happens
For the past few weeks, my ASUS ZENFONE 5Z has been disconnecting from my mobile network and it is impossible for me to find it again. I have tried using other sim cards, restarting, checking the SIM CARD status, going on airplane mode and back and nothing has happened. On top of that, I am also unable to connect to my perfectly working wifi networks (I have tested them and my laptop connects to them just fine).
The first time it happened, signal came back a few hours later but it is now the second time I am faced with this issue and since I work from my phone it has become a very big hindrance and risk.
What can be done to solve this issue?
