Receiving calls from the US when abroad




    I am traveling to Costa Rica in September. I might have to make and receive calls to and from work (all numbers from and in the US).


    The plan I have appears as "SC NA UTT+10 GB" on my bill.


    Will the person calling me know that I am abroad when they call me? Do they have to do anything different when calling? How much will it cost me if they call me?

    Thank you.
