    How to Use Your Phone Abroad Without Huge Bills

    Avoid surprise international roaming charges and stay connected when traveling outside the United States.

    In this guide (5 steps):

    1. 1.Check your carrier's international plan
    2. 2.Turn on WiFi Calling
    3. 3.Buy a local SIM card at your destination
    4. 4.Use an eSIM for a modern option
    5. 5.Connect to hotel and public WiFi for most tasks
    1

    Check your carrier's international plan

    ~17s
    Before traveling, call your carrier or check their app. T-Mobile and Google Fi include free international data in most countries. AT&T and Verizon offer day passes (around $10 per day) that include your existing plan abroad. Adding a plan for the duration of your trip is the simplest option.
    2

    Turn on WiFi Calling

    ~15s
    On iPhone, go to Settings, then Phone, then WiFi Calling and turn it on. On Android, go to Settings, then Connections, then WiFi Calling. When connected to WiFi, your calls and texts will use WiFi instead of the cellular network, avoiding roaming charges.
    3

    Buy a local SIM card at your destination

    ~17s
    For trips longer than a week, buying a prepaid SIM card from a local carrier at the airport or a convenience store in your destination country can be much cheaper. Look for prepaid data plans — they are widely available in Europe and most tourist destinations.
    4

    Use an eSIM for a modern option

    ~17s
    If your phone supports eSIM (most phones made after 2019 do), you can purchase and activate an international data plan before you leave home through apps like Airalo or Holafly. An eSIM is a digital SIM — no physical card needed. Rates start around $5 for 1 GB.
    5

    Connect to hotel and public WiFi for most tasks

    ~16s
    Use hotel WiFi for emails, maps, messaging apps, and video calls. Download Google Maps offline before you travel by searching your destination, tapping the offline maps icon, and downloading the area. This lets you navigate without using any data at all.
