I'll be spending three months in Europe and I want to message my friends back here in the US using WhatsApp. Is it better for me to activate WhatsApp while I'm here in the US before I head to Europe and connect it to my US number? Or should I wait til I get to Europe to activate and connect it with my European number? I heard you can only activate it once per phone so I want to make sure I do it right.
Thanks!
Thanks!
