What You Need to Know before Going to Taiwan

Before you embark on your Taiwan adventure and pick a suitable plan (like a one month eSIM), it's helpful to understand your data needs and how eSIMs work to ensure a smooth and connected trip.

• eSIM Compatibility: Ensure your phone is unlocked and supports eSIM technology. Most modern smartphones, like iPhone XR/XS and newer or many recent Android models (e.g., Samsung Galaxy S20 and later, Google Pixel 4 and later), are eSIM-compatible.
• Data You Need: Estimating your data depends on your usage. Some providers, like MicroEsim, offer 30-day plans ranging from 3GB to 50GB, allowing you to choose a one-month plan that fits your habits.
  
  • For light use (maps, messaging, occasional browsing), 1-3GB might suffice for a week. 
    
  • For moderate use (more browsing, some social media, light video streaming), you might need 5-10GB. 
    
  • Heavy users (frequent streaming, video calls, large uploads) should consider larger data packages or unlimited plans. 
• Data-Only Plans: Most travel eSIMs are data-only and do not include a local phone number for traditional calls or SMS. You can use internet-based services like WhatsApp, Line, or FaceTime for communication.
• Activation Convenience: A key advantage of eSIMs is that you can purchase and install them online before you travel, often receiving the QR code via email immediately. Your data plan typically starts only when you arrive in Taiwan and connect to the local network, meaning you can set everything up in advance for instant connectivity upon landing.
• Cost-Effectiveness: Travel eSIMs are generally much more affordable than international roaming from your home carrier. For example, some local eSIM data plans can start as low as $3-4 for 1GB packages.

This provider is perfectly suited for digital nomads, remote workers, and heavy data users who engage in activities like frequent video streaming, large file uploads/downloads, or using data-intensive applications. But Holafly is generally priced higher than counterparts' data plans.
