Why Choose a European eSIM Card for iPhone?

An eSIM is a digital SIM built into your iPhone, letting you activate a data plan without a physical card. For frequent flyers, eSIMs are a game-changer. They’re easy to set up, eco-friendly, and ideal for short trips or layovers. Here’s why they’re perfect for business travelers:

• Flexible Plans: Choose short-term plans (1–15 days) tailored to layovers or quick trips.
• Multi-Country Coverage: Many eSIMs work across 30+ European countries, so you stay connected as you travel.
• Cost Savings: Avoid expensive roaming charges from U.S. carriers like Verizon or AT&T, which can cost $10/day or more.

iPhones (XS and newer, including iPhone 14 and 15) support eSIMs, with some models storing up to eight eSIMs. This makes them ideal for travelers who need multiple plans for different destinations. Let’s dive into how to select the right eSIM for your European travels.
