i have a T-Mobile iPhone 13 Pro Max which breaks every call I make every few minutes often requires that I try several times before I connect successfully or the caller calling me several time before a connection is successful.     Many call suddenly get gobble up in the middle of the call.    In other cases, when I call the other person does not hear me and I can’t hear her for up to  a minute.    

This problem has been going on for three months and now it is unbearable because it happens to every I make.    T-Mobile has not helped me because I got cut off while speaking to them after being in a queue for 10 minutes.   When I call again, i am made to wait for another ten minutes and wind up not getting any help,

is there someone out there who can help?
