Okay, having issues with my dad's mobile service. My dad and I am on the same deal and bill. We have the same phone except his is a white iPhone 8plus and mine in a gold iPhone 8 plus and the only other difference in our telephone numbers and we live in the same house.
Now the problem is that when you call my dad you have to call him twice, the first time it goes directly to his voice mailbox, which then tell you that this number is not valid, you call again 5 sec later and it rings his phone and if he doesn't answer it goes to voice mailbox and still doesn't register his number but he can pick it up and speak to whomever has called him. I am not having any issues with my phone with people tring to call me.
We have called Telstra and they said they would look in on it but its not high on their priority list (I assume not a lot of people have this issue).
Has anyone had the same issue and if so have you fixed it and if so what did you do.
My dad has missed out on a few important call like a friend wife had passed away and my dad didn't know and missed the funeral and being there for his friends for support like he was their for my dad when my mum passed away.
Thanks
Does it happen with the same sim in another phone?
If not, Apple Store for repair?
