Data by country / Jamaica
How much data do I need for 3 days in Jamaica?
A typical traveller uses about 480 MB to 2.5 GB over 3 days in Jamaica. Buy a plan of at least 3 GB, or an unlimited one, and more if you stream video or make video calls on mobile data.
Where the 3-day figure comes from
The typical profile assumes half an hour of navigation, an hour of social media and half an hour of browsing each day, plus 30 to 100 MB of messaging and background traffic. That is 160 MB to 835 MB a day, so 3 days comes to 480 MB at the low end and 2.5 GB at the high end. The spread is mostly social media: feeds without video use about 120 MB an hour in the carrier figure we use, while feeds full of short video reach 700 MB an hour.
| Activity (typical profile) | Per day | Over 3 days |
|---|---|---|
| Navigation | 3 MB–5 MB | 8 MB–15 MB |
| Social media | 120 MB–700 MB | 360 MB–2.1 GB |
| Browsing and email | 8 MB–30 MB | 23 MB–90 MB |
| Messaging, email and background apps | 30 MB–100 MB | 90 MB–300 MB |
| Total | 160 MB–835 MB | 480 MB–2.5 GB |
Rates: navigation and social media from Consumer Cellular; browsing and email from AT&T's data calculator; all checked 2026-10-19. Full list on the methodology page.
If you stream or call: the heavy profile
Add half an hour of video, a quarter hour of video calls and an hour of music a day on mobile data, with navigation and social media at the higher setting, and 3 days in Jamaica rises to 2 GB to 12 GB. Video streaming alone spans 375 MB to 3.8 GB over the trip, because the Netflix app's Automatic setting uses about 250 MB an hour while HD streaming uses about 2.5 GB. If that is you, plan for 13 GB or an unlimited plan.
Is Jamaica cheap or expensive for mobile data?
On the expensive side. Jamaica ranks 25 of 25 destinations here for price per gigabyte: the best fixed plan on file is $2.3 per GB against a median of $1.2. That makes the habit questions matter more than usual; cutting video to Wi-Fi only can halve what you pay. Unlimited plans start at $2.3 a day, rank 7 of 25; for a 3-day trip that is $6.8, which undercuts buying the heavy-use 13 GB at the fixed rate.
