iPhone 17 + eSIM: The Ultimate Travel eSIM Guide (2025)
If you’re searching for “iPhone eSIM,” “iPhone 17,” or “travel eSIM,” here’s the quick answer: modern iPhones—including the iPhone 17 lineup—make eSIM the easiest way to get fast, affordable data when you travel. With Figabytes eSIM, you can buy a plan, scan a QR code, and go online in minutes—no plastic SIM, no roaming shock.
What is an iPhone eSIM?
An eSIM is a digital SIM built into your iPhone. Instead of inserting a card, you download a mobile plan (a “profile”) to your device. You can store multiple plans, switch which line handles Mobile Data, and keep your personal number active while using a travel eSIM for data.
Why it matters on iPhone 17: Apple continues to lean into eSIM across newer models, making activation smoother and dual-line setups easier for travelers and remote workers.
Why a travel eSIM beats roaming
Set up in minutes: Buy a Figabytes plan before you fly or on arrival; install over Wi-Fi.
Real local pricing: Pay country/region rates, not daily roaming fees.
Dual-line freedom: Keep your home number for calls/OTPs; use Figabytes for data.
Plastic-free: No tiny cards, no shops, no tray tools.

Connect to Wi-Fi
