I just realized my phone is no longer making or receiving calls. Calls to me go straight to VM. When I try to make calls, it just sits there and then changes to no service. I have been getting lots of no service in the top corner the last couple weeks. And I have not changed the area I normally am in and should be getting service. I have checked for updates, hard started my phone reset the network settings, taking my sim card out and reinserted it. I have no problem receiving texts and imessages nor using any apps or the internet. Just cant make or receive calls. I also noticed the little bubbles that usually turn black in the upper left corner when I have amazing service are always clear now. Never changing no matter where I am. Help!
