If I add the international travel plan to my phone for a month long trip, I know people in the US can call us as a US number and we can call back to the US, too. However, can we call local numbers (to where we are traveling)? For example, if I am going to Japan and need to call a Japanese number, is that included in the international plan's 250 mins or will I be charged extra? Also, to call the Japanese number, do I have to call out like an international number? I've looked and looked, but can't find an easy answer anywhere. Thanks!
