What is current period roaming
So I'm really worried that I am going to be charged extra For international roaming. My friend from Germany has been texting me using Imessage and he said it won't charge me as long as it stays iMessage, but I am just nervous. I am not using wifi for iMessage just my standard data is that going to make a difference? For my current period roaming it says 71 bytes and I'm not sure what that means? Can someone please help I really don't want to rack up a huge phone bill.
