I just opened Apple Card and my phone I am charging is 300$ more than limit. Can I pay 300 on my card so I can purchase

No, Goldman Sachs not permit overpayment. There are many accounts on social media about asking GS and them returning or refusing overpayment. If you want to ask, here’s their contact information.

I know I was once going on a trip with anticipated expenses more than my credit limit. I prepaid $1,000 into my account so I actually ended up having a $3,000 availability instead of just my $2,000 credit limit (this was 30 years ago).
