Mobile Network State disconnected

[TonyG]

I can't seem to make or receive calls.  When I try to make a call, the phone indicates that it is dialling but there is no sound. I went into the Settings of my Samsung Note 4 and I found an entry on the Status page that says :

Mobile network state

Disconnected

Any ideas of how I can reconnect? My Optus app shows that my bills have been paid up to date.

I can still send and receive SMS though.

Have you tried removing the sim and giving it a quick wipe then installing it again? If that does nothing you can try resetting the network connections.

Edit: I assume you have restarted the phone.

Hi Yeldarb,

I had already rebooted the phone a couple of times and I had removed the battery and Sim card.  I didn't wipe it though.

Anyway, after I got your message, I changed the network to 3G/2G and the phone worked.  I then changed it back to 4G/3G/2G and it still works.  So thanks a lot for your help.

Glad you got it to work. Cheers
