I have an Iphone 12 Pro Max and everyday before 1100-1130 and often several times a day, I can't not make a phone call, all I get is "call failed". It locks up for all calls? Is this a software issue, hardware issue or some type of a setting that I can turn off? I've gone to the Verizon Store and all they can say is to replace the Sim card, which they did, but it didn't help. thank you
