• Flexibility – choose global, regional, or country-specific plans.

Factors to Consider Before Choosing an eSIM

Not all eSIMs are equal. Here’s what you should check before buying:

• Coverage – Does it work in the countries you’re visiting?

• Pricing per GB – Is it cheaper than a local SIM?

• Data type – Unlimited vs fixed plans.

• Speed & 5G – Some eSIMs are still 4G only.

• Hotspot/tethering – Can you share data with other devices?

• App experience – Is setup and top-up easy?

• Compatibility – Does it work with your phone? (Most iPhones, Google Pixel, and Samsung Galaxy support eSIM).
