For most travelers, 10GB to 20GB is the ideal range for a 30-day trip.
One month abroad is very different from a short vacation. Even moderate daily use of maps, ride apps, messaging, bookings, translation, browsing, and social media adds up over 30 days.
The right plan depends less on the destination and more on how connected you want to be every day.
This guide explains exactly how much data you need for 30 days of travel, who can use 10GB, who should choose 20GB, and when unlimited data makes sense.
Quick answer: 10GB can work for light users, 20GB is ideal for many travelers, and unlimited or larger plans are best for heavy users, hotspot use, or remote work.
Best data sizes for a 30-day trip
- 5GB: only very light users
- 10GB: practical budget option
- 20GB: best balance for most travelers
