Apple Card MasterCard accounts, are obviously a MasterCard credit card account. They are accepted at merchants worldwide that accept MasterCard. Visa cards are a different payment network and worldwide Visa accounts and MasterCard accounts are different. It’s kinda like Ford vs Chevy.
Restrictions are an entirely different subject matter and you would have to explain what your question is. All credit cards have restrictions. That’s just the nature of the beast.
I hope this helps. I’m just not sure where you’re headed with your questions and comments. 😀😀
