Choosing the right data amount depends on your travel habits:

• 1–3GB (Light Use) — Maps, messaging apps (WhatsApp, iMessage), email, occasional social media. Suitable for short trips (1-3 days) with Wi-Fi available at hotel.
• 5–8GB (Moderate Use) — Maps, messaging, email, regular social media, some YouTube Shorts, Spotify. Good for 1-2 week trips without constant Wi-Fi.
• 10–15GB (Heavy Use) — Maps, messaging, social media, YouTube, Spotify, video calls, remote work. Suitable for 2-4 week trips or digital nomad travel.
• 20GB+ (Unlimited-ish) — Full streaming, video calls, cloud work, hotspot sharing. For long stays (1+ month), remote workers, or family sharing.

eSIM prices are relatively stable year-round, but there are some patterns to know. During major shopping events (Black Friday, Cyber Monday, Prime Day), you can often find discounts on annual or multi-month plans. Early booking doesn’t usually give discounts for short-term plans, but for long-term plans (90+ days), buying in advance can save 10-20%. The best strategy is to compare prices across providers for your specific destination and data needs before buying.

• Check destination coverage first — Not all plans cover all countries
• Match data to your real usage — Overbuying is wasteful, underbuying is inconvenient
• Look at network speed — 5G plans cost more but are faster where available
• Check plan validity — Some plans expire after 30 days, others are valid for the duration of your trip
• Read the fine print — Some plans throttle speed after a certain threshold
• Consider top-up options — Choose a provider that lets you add more data easily
