travel. Many eSIM plans, including those offered by Commbitz, are data-only, raising the
question: how do you make phone calls? Here’s a step-by-step guide to making calls with a
data-only eSIM while exploring the best connectivity options like the Commbitz global SIM

    allow you to make calls using your eSIM’s data connection. Simply download one of these
    apps before your trip and use it to make calls anywhere in the world.
  3. Enable Wi-Fi Calling
