eSIM plans · CaribbeanGrenada eSIM: How Much Data You Need (2026)
HelloRoam takes 31 currencies at checkout. Airalo, Holafly, Nomad and Saily take one. A 7-day Grenada trip at 1.5 GB a day needs 11 GB, and the 20 GB tier covers it for $164.45, on a published list naming FLOW. Airalo covers more, 200+ destinations to HelloRoam's 186.
A 7-day visit to Grenada means 11GB of mobile data for a moderate user, at 1.5GB a day for maps, messaging and social media. FLOW carries the 4G LTE label on HelloRoam's published list here. The 20GB plan at $164.45 covers that with 9GB to spare. For heavy users on the 3 GB band, HelloRoam sells unlimited data in Grenada at $18.00/day.
One operator carries Grenada on the published list, FLOW.
Data needs in Grenada split into three bands. Light travelers cover 4GB over 7 days on the 0.5 GB band, maps and email only. Moderate travelers (11GB total) add social media and ride-hailing at 1.5GB/day. Heavy travelers (21GB total) stream video and run hotspots at 3GB/day. 1 carrier and 6 4G LTE plans service all three segments.
Here is the plan match for each traveler type. At $40.80, the 5GB plan handles 7 days of basic navigation and email without overspending. Moderate users: the 5GB plan at $40.80 ($8.16/GB) hits the best price-to-data balance. $18.00/day buys unlimited data on the local network on the published list, which removes the 3 GB a day guesswork for heavy users.

Posting photos and browsing through a week in Grenada? Holafly wins this tier 96 to 86, with HelloRoam second. The cheapest gigabyte at this usage is also Holafly's, $1.99. The provider our rubric puts first scores 86 here, which is not enough. A 5 GB plan for Grenada runs $40.80.

Running a whole working day off mobile data in Grenada? The match score puts Holafly first here, 96 to HelloRoam's 66. The cheapest gigabyte at this usage is also Holafly's, $1.00. HelloRoam finishes on 66 and loses the tier. Saily and Nomad cap you at a fixed bundle, which for a heavy week means paying for the ceiling. A 10 GB plan for Grenada runs $74.66, and unlimited runs $18.00 a day.

Every figure in the rate column starts life as a published entry price, then gets expressed per gigabyte at the tier's daily usage. A per-day plan and a per-GB plan only meet on that one scale. Published entry rates: Airalo $4.50/GB, Saily $3.99/GB, Holafly $2.99/day, Nomad $3.00/GB, HelloRoam $3.50/GB. Those are catalogue floors, not prices for Grenada. Where a plan price for Grenada appears above, it is HelloRoam's. That is the one per-destination price feed we hold. The other four publish a floor and nothing destination-specific we can verify, so we quote no Grenada price for them at all.
How trip length changes your Grenada plan
Short trips and extended stays need different data strategies. Find your trip length below.
Short trip (1-3 days)
Short trips to Grenada use 5GB total. The 5GB at $40.80 fits 3 days of social media and navigation.
Standard trip (5-10 days)
Standard trips to Grenada total 11GB. The 20GB at $164.45 handles a full week of social media and maps.
Extended stay (14-30 days)
Trips longer than 2 weeks in Grenada need 32GB or more. Unlimited at $18.00/day saves money past day 10.

Who you're connecting to
In Grenada, the underlying carrier matters more than the brand on your plan.
Carrier routing determines the right plan for each traveler type in Grenada. FLOW is the 4G LTE network most visitors to Grenada spend the trip on, strongest in the metro areas. None of the five publishes which of those carriers it uses here, so pick on plan shape and cover instead. Since the underlying network is fixed, the useful comparison is plan shape and what happens when a plan does not fit. If you would rather not think about gigabytes in Grenada, Holafly sells only unlimited days, published from $2.99/day. Fair-use throttling kicks in past the daily threshold and tethering caps at 1GB. If you work from cafes in Grenada, Saily's VPN layer encrypts traffic without a second app. Plans start at $3.99/GB and Saily support runs in 1 language, by email only. Sticking to maps and messaging? Nomad publishes the cheapest gigabyte here at $3.00/GB. Nomad refunds inside 30 days and sells one plan shape, with no unlimited tier. HelloRoam publishes the widest support access of the five, 63 languages on chat, WhatsApp and email around the clock, plus 180 days to refund an unactivated eSIM. It does not win price at $3.50/GB. Since all 1 carrier in Grenada run 4G LTE, your usage tier drives the plan choice more than the network name.
HelloRoam publishes its local operator list for Grenada, and the next section prints that list in full. The other four providers publish no equivalent list, so the cards below carry published facts about each provider instead of a carrier we would be guessing at.

Who you connect to in Grenada
HelloRoam publishes one local operator for Grenada. That operator is FLOW. 117 of the 185 destinations HelloRoam publishes work this way.
One operator means no fallback. Where the FLOW signal drops, no second network takes over. Save offline maps for Grenada before you fly.
HelloRoam lists no 5G operator in Grenada, so expect 4G on the ground. Operator count does not change your plan size, so pick the tier by trip length.

What uses your data in Grenada
Activity-level data breakdown for a Grenada trip.
Streaming
Streaming moves a traveler into the heavy band, which the published benchmark puts at 3 GB a day. 7 days in Grenada at that rate comes to 21 GB, and the 20GB plan at $164.45 is the smallest Grenada tier that clears it. Downloading episodes over hotel WiFi keeps the day inside the 1.5 GB moderate band instead.
Navigation
Navigation alone keeps a Grenada trip on the 0.5 GB light band. That is 4 GB across 7 days, which the 5GB plan at $40.80 covers. Save the Grenada map region over WiFi before you fly and the same trip draws less.
Social media
The moderate benchmark is 1.5 GB a day, which is what social apps plus messaging draw. Across 7 days in Grenada that is 11 GB. The 20GB plan at $164.45 covers the trip.
Work tools
Video calls run at the heavy benchmark of 3 GB a day. A 7-day working trip to Grenada needs 21 GB, and the 20GB plan at $164.45 is the smallest tier that covers it. Audio-only calls drop the same day back toward the 0.5 GB light band.
Your Grenada pricing notes
If you compare per-GB rates across Grenada plans, bigger tiers win on unit cost: 1GB at $10.98 ($10.98/GB), 3GB at $26.10 ($8.70/GB), 5GB at $40.80 ($8.16/GB), 10GB at $74.66 ($7.47/GB), 20GB at $164.45 ($8.22/GB). The 5GB tier delivers the strongest moderate-user value: $40.80 total, $8.16/GB, covering 4 days of 1.5GB daily use. If you only need email and maps, 1GB at $10.98 keeps you connected without paying for data you will not use. Heavy users compare two paths: 20GB fixed at $164.45, or unlimited at $18.00/day. The crossover point is 9 days. A 30-day unlimited plan drops to $14.76/day (18% off). Streaming daily? Holafly's published $2.99/day unlimited is the shape that fits. Under a gigabyte a day, Nomad's $3.00/GB fixed rate wins the maths. Looking for the cheapest eSIM in Grenada? The lowest destination price we hold is 1GB at $10.98 from the catalogue. Nomad publishes the lowest fixed entry rate of the five at $3.00/GB, though not a Grenada figure we can stand behind.

Regional bundle vs single-country plan
If your trip covers multiple countries in Caribbean, a regional eSIM bundle avoids buying separate plans for each stop. Single-country plans for Grenada start at $10.98 for 1GB. Compare the per-GB cost of a regional bundle against individual plans to find the cheaper path for 7+ days.
How to activate your Grenada eSIM
Pick the plan that matches your daily data target for Grenada. Scan the QR code under Settings > Cellular > Add eSIM while connected to WiFi at home.
If you want to receive calls on your home number while abroad, keep both lines active. Set the eSIM as "Travel Data" for internet and your home SIM for voice.
If your eSIM is pre-installed, FLOW connects the handset to 4G LTE in Grenada the moment your phone leaves airplane mode. Setup runs under 30 seconds.
Common Grenada eSIM questions
Direct answers grounded in real plan data and carrier coverage.
What plan do I need?
The eSIM plan you need for Grenada depends on how you use data. A light user (maps and messaging) needs about 1GB, covered by the 1GB plan at $10.98. A moderate user (social media and navigation) needs 3GB at $26.10. A heavy user (streaming and video calls) needs 25GB at $164.45. Those are catalogue prices for Grenada, and the plans run on the local network on the published list.
How much data do I need?
Data usage in Grenada breaks down by app. The published bands are 0.5 GB a day for light use, 1.5 GB for moderate and 3 GB for heavy. Maps and messaging sit on the light band. Streaming and video calls sit on the heavy one. For 7 days, most travelers need 3GB (0.4GB/day). WiFi in Grenada is available at hotels and some restaurants, offsetting about 10% of usage.
Which provider is cheapest?
Nomad publishes the lowest fixed eSIM rate of the 5 providers we score, at $3.00/GB. The cheapest Grenada plan in our price feed is 1GB at $10.98 on the local network on the published list, a catalogue price. Published entry rates: HelloRoam from $3.50/GB, Holafly from $2.99/day, Airalo from $4.50/GB, Nomad from $3.00/GB, Saily from $3.99/GB. Those are catalogue floors, not Grenada quotes. For a 7-day trip needing 11GB, compare the total cost, not the headline rate.
Is an eSIM worth it?
An eSIM is worth it for Grenada. WiFi in Grenada covers hotels and some public areas, but an eSIM keeps you connected everywhere. The 20GB plan at $164.45 gives you 11GB on the local network on the published list for 7 days. That is $-54.45 less than carrier roaming.
eSIM vs SIM card?
An eSIM is better than a physical SIM card for Grenada in most cases. eSIM plans start at $10.98 for 1GB and activate in under 5 minutes from your phone. Airport SIM cards cost $15-25 after a 15-30 minutes wait at the local network on the published list counters. The eSIM runs on the same the local network on the published list network.
How to set up?
Set up your Grenada eSIM before boarding. Buy and install the plan while on home WiFi. The eSIM activates on FLOW when your phone detects the local network. Grenada plans start at $10.98 for 1GB on the catalogue. Keep your home SIM active for calls and use the eSIM for data.
Plan match by traveler profile
Each profile maps to a specific plan size and provider for Grenada.
Backpacker
A backpacker heading to Grenada should budget 7 GB for maps and messaging across 14 days. That lands on the 10 GB plan, $74.66 on the local network on the published list. HelloRoam fits the shape of this trip, and publishes 63 support languages.
Backpackers staying 7 days in Grenada need 4GB for navigation and hostels. The 5GB plan at $40.80 matches.
Business traveler
A business traveler uses 15 GB across 5 days in Grenada on video calls and uploads. The 20 GB plan at $164.45 matches that on the local network on the published list, at $8.22 per GB. Of the five we score, HelloRoam publishes the plan shape that fits, at an entry rate of $3.50/GB.
Business travelers on video calls burn 21GB over 7 days. Unlimited data at $18.00/day on the local network on the published list removes the cap.
Family group
A family traveler uses 14 GB across 7 days in Grenada on social media and navigation. The 20 GB plan at $164.45 matches that on the local network on the published list, at $8.22 per GB. HelloRoam fits the shape and refunds an unactivated eSIM for 180 days.
Three travelers sharing Grenada data need 32GB for 7 days. Each grabs the 20GB at $164.45 on the local network on the published list.

Your questions, answered
How many gigabytes per day should I budget in Grenada?
Budget 0.5 GB a day for maps and messaging, 1.5 GB a day for social media and browsing, and 3 GB a day if you stream. Over a 7-day Grenada trip those rates come to 4 GB, 11 GB and 21 GB. Most visitors land on the middle rate, so the 20 GB plan at $164.45 covers the moderate figure on the local network on the published list. Past 3 GB a day the fixed tiers run out here, and unlimited days at $18.00 take over. Pick the daily rate that matches your habits at home, because a trip rarely changes them.
Which plan shape fits my Grenada trip, fixed tiers or unlimited days?
If you stream video or run work calls most days in Grenada, take the unlimited shape at $18.00 a day. If you keep to maps, messaging and evening browsing, take a fixed tier: a 7-day trip at 1.5 GB a day needs 11 GB, which the 20 GB plan covers at $164.45. Shape availability is not the same everywhere. Only Holafly publishes an unlimited daily plan everywhere it sells. With HelloRoam and Airalo, unlimited depends on where you are going. Nomad and Saily sell fixed per-GB tiers and nothing else. Holafly publishes no gigabyte bundle, which is what you give up for uncapped days.
Which eSIM plan fits a light or heavy data user in Grenada?
Match your 7-day Grenada trip to a plan tier before you buy. A light data day of 0.5 GB across 7 days totals 4 GB. The 5 GB plan at $40.80 fits that profile. A moderate day of 1.5 GB across 7 days reaches 11 GB. The 20 GB plan at $164.45 covers it. Heavy users at 3 GB a day hit 21 GB, and the 20 GB plan at $164.45 ($8.22/GB) is the largest tier sold here, so a heavy pace needs a second purchase or an unlimited plan.
What should I check on my phone before I buy a Grenada plan?
Check three things: the model, the EID and the lock status. iPhone XS (2018) and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later all handle eSIM. Dial *#06# and look for an EID number below the IMEI, which is the line that confirms support. Your phone also has to be carrier-unlocked. Pass all three and Grenada's 4G LTE network connects on its own once the profile installs, with no SIM tray involved. The spelling varies from site to site, e-SIM and e SIM included. The technology does not.
What starts the clock on a Grenada plan, the purchase or the landing?
Landing starts the clock, so time the purchase to the flight. Buy 1 to 3 days before you fly and install the QR code over home WiFi, which does not trigger the countdown. The first network connection in Grenada does. The 1 GB plan at $10.98 suits a short stay. The 20 GB plan at $164.45 suits a longer one. Installing early is the part that matters: airport WiFi is the worst place to discover a QR code will not scan.
Is Grenada well-covered by travel eSIM networks in Caribbean?
For a Caribbean trip centred on Grenada, the picture is simple. 1 operator (FLOW) deliver 4G LTE service, and travel eSIMs ride the same infrastructure as local SIMs. Coverage is strongest in urban centres and transport hubs. The 5 GB plan at $40.80 ($8.16/GB) fits a standard Caribbean visit. If the trip grows another leg, check reach before loyalty. Each provider publishes its own destination count: Airalo, Nomad and Saily at 200, HelloRoam at 186 and Holafly at 160.
Which activities use the most mobile data in Grenada?
The photo sharer and the navigator both live inside the 1.5 GB moderate band in Grenada. The streamer and the remote worker both live on the 3 GB heavy band. That is the whole split, and it is the split the tier ladder is built around. The 5 GB plan at $40.80 covers a moderate traveller on the local network on the published list, at $8.16/GB.
How do I match a Grenada plan tier to the number of nights I am staying?
Count the nights, multiply by 1.5 GB, and buy the first tier above that number. For Grenada at a moderate pace that maps out as: 1 to 2 nights takes the 3 GB plan at $26.10 ($8.70/GB); 3 nights takes the 5 GB plan at $40.80 ($8.16/GB); 4 to 6 nights takes the 10 GB plan at $74.66 ($7.47/GB); 7 to 13 nights takes the 20 GB plan at $164.45 ($8.22/GB). The 10 GB plan holds the lowest per-GB rate here at $7.47/GB. Add 20% on top if you stream video or run navigation for whole days, because a tier that fits exactly leaves you rationing on the last morning.
How many days must I commit to for unlimited pricing in Grenada?
Three numbers decide it. The floor is 1 day at $17.28. The base rate is $18.00 a day. The longest block, at 30 days, cuts that to $14.76 a day, or 18% off. Full 4G LTE speed runs to 2GB a day before fair-use terms apply. Book the block that matches your nights in Grenada, since a shorter block topped up later costs the base rate again.
Which provider backs up a mis-sized Grenada plan?
Two things back up a wrong choice, and both are published. The first is the refund window on an unactivated eSIM: HelloRoam and Holafly publish 180 days, Nomad and Saily 30 days and Airalo 14 days. The second is who answers when something needs fixing: HelloRoam publishes support in 63 languages, Airalo 12, Holafly 10, Nomad 2 and Saily 1, and HelloRoam takes live chat, WhatsApp and email, around the clock. Neither helps once the plan is running in Grenada, so the useful move is to size correctly and buy close to departure. Sizing up first is still cheaper than any refund: the 10 GB plan holds the lowest rate here at $7.47/GB.
