No sound both ways during calls

Hi, I recently broke my phone so I swapped back to my perfectly fine old phone, the Galaxy S4.


However I've noticed that the calling doesn't work. There is no sound both ways. I can't hear them, and they can't hear me. I know it's not the speaker and mic issue because I tested them using an app and I also tried calling with headsets on.


I tried calling through an calling app and others like Facebook messenger, Skype and etc. Those work but only SIM calls do not. I'm wondering if it's my phone rejecting the SIM calls or from Fido. My lte and texting works fine and this is a Fido phone.


Thank you for your help!

Hey @junewi!


We haven't heard back from you. 


Were you able to figure out what was going on? Did any of my suggestions help?


It'd help out the Community if you had any updates for us!

Hey junewi!


Welcome to the Community!


That's definitely a bizarre situation. 


Have you tried performing a factory reset of your Galaxy S4 to see if that changes anything?


Is the same thing happening when you move your SIM card to another phone?
