For most travelers, 5GB to 10GB is the ideal range for a 14-day trip.
Two weeks abroad is long enough that data planning matters. A plan that feels fine for 3 or 5 days may run out early if you travel for 14 days and use maps, ride apps, bookings, social media, and messaging every day.
The right amount depends on your travel style, not only the number of days.
This guide explains exactly how much data you need for 14 days of travel, who can use 3GB, who should buy 10GB, and how to avoid overpaying.
Quick answer: 3GB can work for light users, 5GB is a smart minimum for many travelers, and 10GB is ideal for comfort and moderate daily use over 14 days.

- 3GB: light travelers using Wi-Fi often
