- Check phone compatibility: Ensure your phone supports eSIM technology. Confirm if your chosen provider works seamlessly with your device.
- Compare data plans: Estimate your data needs—unlimited plans are ideal for heavy users, while smaller packages suit light browsing.
- Evaluate price and features: Look for plans that fit your budget and check for extras like hotspot sharing or rollover data. Compare the validity periods to ensure the plan covers your entire trip.
- Consider ease of use: Choose providers with simple activation (e.g., QR codes) and good customer support. Trusted providers like Holafly offer reliable, user-friendly experiences.
Pro Tip: If you’re unsure, prioritize ease of activation and strong support over minor price differences—this can save you headaches during your travels.
