iPhone 12 Pro Max cellular service dropping

I Have the same problem in the Netherlands. It happend more then 5 times today. When i call with some who has an iphone 12 too we must call eachother back a few times. Because i have a lot of business calls it is a real issue.

It doesn't seem to be a network problem. I am having the same problem outside of the US and using a different service provider. Its very annoying.

Ask yourself: Who sends the signal?
