How can I call Japan from the US?

Question

I am trying to call a friend's cell phone in Japan from the US. He gave me this number: 09030421XXX ( I substituted exes for the last three numbers). How do I call this number from the US. I tried 011-81 and then the number. That didn't work. Help! It is very important that I contact him.

Answer 1

♡Omit the first "0" from the telephone number.
011-81-9030421XXX
Try that, it should work.
Good luck and I hope this helps!
～☆By the way, that number is a cell phone number, so if you get a Japanese recorded message, the phone is either turned off, out of range or has the answering system on. Try calling again.♡
