Start with your days ashore and your normal habits
A resort holiday, an island-hopping trip and a cruise can have very different mobile-data patterns. Estimate maps, messages, tickets and browsing first, then add uploads, app calls and any hotspot use. Check your phone’s mobile-data history rather than combining Wi-Fi and mobile traffic into one number.
The following examples are illustrative calculations, not measured traveller averages or guaranteed requirements. Video settings, cloud backups, app updates and Wi-Fi availability can substantially change the result.
Three useful planning scenarios
Light assumption: 0.25GB/day plus 20% buffer. This gives 2.1GB for seven days, 4.2GB for fourteen days or 9GB for thirty days.
Higher assumption: 0.75GB/day plus 20% buffer. This gives 6.3GB for seven days, 12.6GB for fourteen days or 27GB for thirty days.
Heavy assumption: 2GB/day plus 20% buffer. This gives 16.8GB, 33.6GB or 72GB respectively. These are calculated quantities, not exact package sizes. Formula: daily use × trip days × 1.2. Choose an available allowance with suitable validity.
Seven days: make room for arrival and excursions
A fixed 1GB/7-day package is one gigabyte for the whole period, not one per day. It falls below the light illustrative 2.1GB budget above. A package’s validity matching the holiday does not mean the allowance necessarily matches your habits.
Download maps, transfer addresses and booking confirmations before departure. Keep backups and larger files on Wi-Fi where practical. A hotel stay with dependable Wi-Fi may leave mobile data mainly for outings, while frequent uploads away from the hotel need more room. Count arrival and departure days as well as hotel nights.
Fourteen days: a total pool or a daily allowance?
A fixed pool lets you use more on an excursion day and less on a quiet resort day. Daily high-speed limits apply separately by day; do not assume unused high-speed data rolls into tomorrow. Under the 0.75GB/day example, fourteen days needs 12.6GB including the illustrative buffer.
Daily Unlimited Lite provides 1GB/day high-speed, then up to 512 kbps. Essential provides 1GB/day high-speed, then up to 1.25 Mbps. Plus provides 2GB/day high-speed, then up to 2 Mbps. High-speed allowances refresh daily; unused daily high-speed data should not be assumed to roll over. Unlimited does not mean unrestricted full-speed data.
Choose by both high-speed amount and post-allowance speed. Local reception and congestion still affect performance, so the stated reduced speed is not a guarantee of actual throughput.
Thirty days: check the product’s duration limits
The Caribbean regional listing, Jamaica, Barbados and Saint Lucia offer fixed packages up to 50GB/30 days, but daily Unlimited only up to 15 days. A 15-day package does not last a month because its allowance seems generous.
The Dominican Republic country product has different choices: fixed data up to 100GB/30 days and daily Unlimited up to 30 days. That does not extend its country coverage to neighbouring islands. For a longer multi-island stay, compare current options rather than assuming automatic renewal, an identical top-up or a 30-day daily tier exists everywhere.
Cruise days and shared data change the calculation
For cruises, estimate land-network use separately from onboard Wi-Fi. The cruise connectivity guide explains why a travel eSIM does not supply maritime or satellite service. Sea days still count after the plan activates; they do not pause its expiry.
For hotspot, check exact-package permission and limits before buying. Shared traffic consumes the same allowance. Combined phone and laptop use can be much higher than messaging alone, especially with updates, photo sync and meetings. If others share your hotspot, budget for their traffic too.
Finish with coverage, device and number checks
Confirm every destination in the selected product’s list before choosing gigabytes. The regional label does not include every island; Cuba needs a separate comparison through the existing Cuba guide. Data-only products do not include a local number, ordinary calls or SMS.
Use an eSIM-compatible, carrier-unlocked device. Install over Wi-Fi, follow the purchased activation instructions and monitor use during the first few days. Border crossings do not refill fixed data or reset validity. Save essential travel information offline for remote outings and boat journeys.
