The amount of data needed in Jamaica depends more on video, uploads and tethering than on maps or messages. Trip length matters, but two travellers on the same itinerary can have very different usage.
Quick answer: Light users can often plan around 500 MB–1 GB per day, moderate users around 1–2 GB per day, and heavy video or hotspot users considerably more. Check actual phone usage before choosing a plan.

A traveller mainly using maps, text messages, email and occasional browsing may need roughly 500 MB to 1 GB per day. Downloading Jamaica map areas and hotel information on Wi-Fi reduces the requirement.
For seven days, 3–7 GB can be a practical starting range when video and cloud backup remain restricted.
Moderate use: social media and calls
Regular photo uploads, scrolling social feeds and internet voice calls can push use toward 1–2 GB per day. A one-week trip may therefore need approximately 7–15 GB, depending on Wi-Fi availability.
Video calls consume more than voice calls. Reduce video quality or use trusted accommodation Wi-Fi for longer sessions.
Heavy use: streaming and hotspot work
Video streaming, large uploads and laptop tethering can consume several gigabytes in a day. Check whether the selected plan supports hotspot use and whether an unlimited option reduces speed after a high-speed threshold.
Remote workers should measure laptop traffic separately from phone use. Cloud synchronisation and software updates can exceed ordinary travel activity.
Check your existing usage
Review the mobile-data statistics on the phone for a representative week, then subtract activity that will occur on Wi-Fi. Add a margin for delays and route changes rather than automatically choosing the largest allowance.
Pause automatic app updates, photo backup and media downloads before departure. The Jamaica unlimited-data guide explains fair-use and speed limits.

FAQ
Is 5 GB enough for a week in Jamaica?
It can be enough for maps, messaging and light browsing when video, updates and cloud backup are limited.
Is 10 GB enough for a Jamaica trip?
For many moderate users, 10 GB can cover a week of maps, messages, browsing and some social use. Video and hotspot work change the calculation.
Does Google Maps use much data?
Ordinary navigation is relatively light, especially when map areas are downloaded before travel.
Does hotspot use consume more data?
It often does because laptops and additional devices run backups, updates and richer websites in the background.
Final Recommendation
Start with actual recent usage, match it to the trip length and add a sensible margin. Control video, cloud backup and tethering rather than paying for a large allowance that the itinerary does not require.
