Your eSIMFlyer USA plan is specifically tailored for connectivity within the United States. If your North American itinerary includes venturing north to Canada (perhaps to see Niagara Falls from the other side) or south to Mexico (for a Cancun getaway), your USA eSIM will not provide service there. For frequent flyers with cross-border adventures, we recommend exploring our regional North America eSIMs or purchasing separate country-specific eSIMs to ensure you remain connected throughout your entire journey.
