Mobile Network State disconnected


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



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. Smiley Happy

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 Smiley Happy

Can be a problem of sim, try to remove it from the rub a little and put it back, if nothing, if you have the opportunity to test it in another mobile or go to the shop to test and eventually change it.

Seeing as this threads seems to get an oddly high number of views each month, I'm just going to include a couple of handy links:
