No, Xfinity Mobile doesn’t automatically include international service. You need to pay extra to add international service to your plan. Prices also differ depending on the country for which you need international service. For example, you can pay a flat $10 rate for the Global Travel Pass for each day that you’re in Japan if you want unlimited texts, calls, and data. You can check the rates for the particular country using the global rates calculator on the Xfinity website.
