Grenada Roaming Price Audit: $12 a Day Against a $164.45 Plan
HelloRoam is the top pick for Grenada on this site's rubric, though its 7-day unlimited plan there costs $110.88, at full speed for the first 2 GB a day, above the $84 a week on AT&T's $12-a-day pass, so for one week the day pass costs less, and Holafly ranks second on this site's rubric. HelloRoam's support replies in your own language over live chat, WhatsApp and email. Airalo covers 200+ destinations to HelloRoam's 185. HelloRoam's price is from its catalogue of 29 Oct 2026, rivals' from the 30 Oct 2026 price check; AT&T's rate was checked June 2026.
Currency is the column nobody prices. HelloRoam settles a Grenada order in 31 currencies, and a dollar charge on a euro or sterling card picks up 2 to 4 percent at the bank.

Pay-per-use cost audit
AT&T pay-per-use costs in Grenada: a scenario breakdown
One day in Grenada without an international plan: typical phone use runs roughly 450 MB. At AT&T's $2.05/MB pay-per-use rate, that day costs $922. Breakdown: 1 hour of navigation ($102), 30 minutes of Zoom ($922), uploading 20 photos ($410), light social media. One day with a Grenada eSIM on a local network: roughly $1.57 when you spread the plan cost across your trip. AT&T's International Day Pass is $12/day and avoids pay-per-use entirely — but even that costs more than most eSIM plans cover for the same period. Source: AT&T rate card, June 2026.

Your Grenada saving against $12 a day
Adjust the trip length, the carrier and the daily data below and the calculator reprices both sides. The starting point is the 10-day average stay recorded for Grenada: $120 on an AT&T day pass at $12 a day, against $164.45 for a 20GB travel eSIM. Both prices buy access to the same local operators.
Network coverage
Grenada network performance: speeds and coverage
FLOW operates the sole mobile network in Grenada. US carriers pay FLOW for roaming access and pass that cost to you at $12/day. Travel eSIMs use the same FLOW agreement at $7.47/GB. Local operators own the towers. Both options rent access. The eSIM rents it cheaper. Grenada runs 4G LTE on a local network. That is enough for maps, streaming, and video calls. Carrier roaming and eSIMs deliver that same speed. AT&T charges $12/day for it. An eSIM charges $7.47/GB.
Network attachment record
The networks behind both prices in Grenada
HelloRoam publishes one local operator for Grenada: FLOW.
One operator means no fallback network.
Where FLOW has no signal, an eSIM has nowhere else to attach.
HelloRoam records no 5G operator for Grenada.
Carrier roaming meets the same ceiling, because roaming rents local networks.
Price is what separates the two options in Grenada. This page prices both.
5G and 4G here are capability labels. Neither one is a speed reading.
HelloRoam's operator record names FLOW for Grenada. The same file holds 185 destinations, 154 distinct operators and 98 destinations with at least one 5G entry. Nothing in it says which operator a handset picks, and neither does this page.

Pricing breakdown
Per-day data costs in Grenada: roaming and eSIM
Verizon TravelPass for Grenada: $12/day x 14 days = $168. AT&T International Day Pass: 10 daily fees × $12 (AT&T's cap per bill cycle) = $120. A 10GB eSIM on a local network covers the full 14 days for $74.70. That is $45.30 less than AT&T and $93.30 less than Verizon.
T-Mobile's International Pass in Grenada costs $10/day, the lowest daily rate of the three major US carriers. AT&T is $12/day. Verizon is $12/day. An eSIM on a local network averages $5.34/day when you buy the 10GB plan upfront.
Choosing the right eSIM tier for Grenada depends on trip length and daily habits. Available tiers: 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). A 1.5 GB/day user on a 14-day trip needs roughly 21GB. The unlimited daily option at $14.40/day works out to $201.60 total.
Grenada publishes five unlimited durations: 1 day at $18, 3 days at $51.30, 7 days at $110.88, 14 days at $201.60, 30 days at $367.20. Buying the 30-day block brings the daily price to $12.24. Unlimited here means 2GB a day at full speed before a fair-use policy applies. Catalogue prices read 29 Oct 2026.
Trip cost breakdown
Grenada trip cost breakdown: 3 days, 14 days, 30 days
AT&T bills $12/day for roaming in Grenada — that is $0.50/hour around the clock, whether your phone is in your pocket or active. A 2GB eSIM on a local network costs $26.10 for 3 days — $0.36/hour at continuous use. Difference for a 3-day trip: $9.90.
Over 14 days, AT&T's per-hour rate stays at $0.36. A 20GB eSIM on a local network for 15GB averages $0.49/hour over the same 14 days. AT&T total: $120. eSIM total: $164.45. Difference: $-44.45.
A 30-day stay at $0.17/hour on AT&T reaches $120. A 50GB eSIM on a local network covering 50GB for video calls and streaming costs $388.55 — $0.54/hour. Total difference over 30 days: $-268.55 (-224%). Rates checked June 2026.
Airport options
Getting connected at Grenada airports
Airport SIM counters in Grenada sell prepaid data cards to arriving travelers. The transaction requires your passport and takes 15-30 minutes including queue time. A travel eSIM on a local network costs $10.98 for 1GB and installs before departure. You land with data already active.
Data planning
Grenada data allowance guide: 7-day stays
Navigation apps use about 50 MB/hour while routing. Four hours of map use per day in Grenada burns 200 MB before you touch social media or email. Total daily data lands near 1.5 GB for most travelers. A 7-day trip needs 11GB.
The 20GB plan covers your 7-day trip for $164.45. AT&T's roaming cost for the same 7 days is $84. The difference is $-80.45, enough for two dinners in Grenada. For heavy data users, a 1-day unlimited plan costs $18, not under AT&T's $12/day pass.
Connectivity
Grenada internet access: WiFi coverage vs eSIM availability
Hotel and cafe WiFi reduces your cellular data needs in Grenada, but does not eliminate them. Navigation, real-time transit, and ride-hailing apps all need data outside WiFi zones. AT&T covers those moments at $12/day. An eSIM on a local network covers the same gaps at $7.47/GB — you pay for only what you use.
Plan your data
Grenada data consumption: what to expect
Even a 2-day layover in Grenada costs $24 in AT&T roaming at $12 a day if you leave the plan active. A short-trip eSIM on a local network covers 48 hours for a fraction of that. The cheapest eSIM plan starts at $10.98.
Grenada has one mobile operator: FLOW. US carriers pay FLOW for roaming access and pass that cost to you at $12/day. An eSIM connects to FLOW directly at $7.47/GB — no carrier markup.
Local prices in Grenada are in XCD (EC$), but eSIM plans are priced in USD, eliminating exchange rate uncertainty on your data costs.
Quick reference
Grenada Travel Essentials
911
911 reaches police, fire, and ambulance in Grenada. Save the number before you arrive — do not rely on memory in an emergency. 911 works from any phone, including a travel eSIM with no local number.
Type G
Grenada uses Type G outlets (UK-style three large rectangular prongs). US plugs do not fit — bring a Type G travel adapter. Most US phone and laptop chargers are dual-voltage (100-240V) and work fine with just the adapter.
AST (UTC-4)
XCD (EC$)
Cash in XCD is preferred across most of Grenada outside major hotels and tourist centers. Card terminals are not common in local markets or small restaurants. Withdraw enough cash at a reliable ATM before leaving the city — rural areas may not have ATM access.
Good to know
WiFi in Grenada is moderate. An eSIM ensures you stay connected between resorts and ferry terminals at $7.47/GB.
Good to know
One operator, FLOW, runs all mobile coverage in Grenada. Carrier roaming and eSIM plans use the same infrastructure — comparing costs is the only meaningful variable.
Step by step
How to switch from carrier roaming to an eSIM in Grenada
- Open Settings > Cellular on your iPhone (or Connections > SIM on Samsung) to confirm eSIM support — FLOW runs LTE across Grenada
- On iPhone or Pixel: open the HelloRoam app, search Grenada, and purchase the 1GB plan at $10.98 — your QR code appears in the app the moment payment clears. Compare all providers before deciding.
- On Samsung Galaxy: go to Settings > Connections > SIM manager > Add eSIM and scan the QR code before you leave home so it is ready to activate on arrival
- On Google Pixel: go to Settings > Network > SIMs, select your home carrier, and disable the Roaming toggle. See the complete data roaming guide for all device types.
- First landing in Grenada: if your eSIM does not connect on its own, toggle Airplane Mode on then off — this forces your phone to scan for FLOW's LTE signal
- Returning traveler: if you communicate via iMessage or WhatsApp, WiFi Calling is optional — those apps run over the HelloRoam eSIM data at no added cost and cover most communication needs in Grenada

Forgot your eSIM?
What to do if you arrive in Grenada without data
The fastest emergency option in Grenada: turn on AT&T cellular data long enough to download the Airalo app. The app download is approximately 5 MB. At AT&T's $2.05/MB pay-per-use rate, that download costs $10. Once the app is installed, turn carrier data back off. Connect to the nearest available WiFi, buy a Grenada eSIM plan, and scan the QR code. Your eSIM on a local network then handles all data at $10.98 for 1GB. The $10 carrier charge is a one-time cost, not a daily fee. AT&T's International Day Pass costs $12 for that same day and $12 again for every day after it.
Savings math
How much you save in Grenada
Solo traveler
The $0 a solo traveler saves by choosing an eSIM over AT&T roaming in Grenada covers 0 restaurant meals, 0 museum tickets, or 0 taxi rides in most destinations. That money came from the same local network connection AT&T charges $120 for.
Family trip
Families with children face double roaming costs — two parents on full plans plus two kids whose phones sync games and app updates in the background. In Grenada, AT&T bills $12 a day for the first line and $6 for each extra line used the same day, at most 10 daily fees per line each bill cycle. Four lines for 10 days: $300. A single 20GB eSIM at $164.45 shared via hotspot covers all four devices. Total family cost drops from $300 to $164.45.
AT&T roaming rate analysis
AT&T International Day Pass does not add extra data for Grenada roaming. It uses your existing domestic plan data allowance. A customer with a 5 GB domestic plan who has used 3 GB at home has only 2 GB left for their Grenada trip. After 2 GB, AT&T throttles to slower speeds while the $12/day charge continues. A 20GB eSIM at $164.45 provides a separate data bucket that does not affect or draw from your home plan. This is the key structural advantage over Day Pass: independent data.
All-carrier summary
AT&T: AT&T International Day Pass costs -27% more than an eSIM for Grenada.
Verizon: Verizon TravelPass costs less than this eSIM plan for Grenada.
T-Mobile: T-Mobile's International Passes cost less than this eSIM plan for Grenada.
An eSIM saves money in Grenada for every trip longer than one day. The single exception: a same-day layover where you need your US number active for voice calls. AT&T's $12 for that one day may be worth the convenience. For any trip of 2+ days, the 20GB eSIM at $164.45 saves $0 over 10 days on a local 4G LTE network.

Essentials includes texting but no data. The 1 Day International Pass costs $10. A travel eSIM at $164.45 for 20GB provides full 4G LTE speed on the same local towers. Rates checked June 2026.
AT&T fine print for Grenada

iCloud Photos, email push, app updates all trigger the daily charge. A phone left in a bag with data roaming on starts a new $12 fee each time a sync lands after the last 24 hours ran out.
Grenada FAQ
Grenada eSIM & roaming questions
Grenada carrier roaming costs $12 a day on AT&T and on Verizon
Three US carriers cover Grenada: AT&T at $12/day, Verizon at $12/day, and T-Mobile at $10 for a 1 Day pass, with 5GB or 15GB of high-speed data included on its Experience plans. All three rent capacity from FLOW. So do the five travel eSIM providers priced here: HelloRoam, Holafly, Nomad, Airalo, and Saily, from $10.98 for 1GB. One thing the day pass does that a data-only eSIM does not: it keeps your own number live for calls and texts without WiFi. If you need that and use almost no data, $12/day is a fair trade. If you use data at all, it is not. Rates checked June 2026.
T-Mobile's included data in Grenada runs at high speed until the allowance ends
Not past the allowance. T-Mobile's Experience More plan includes 5GB of high-speed data abroad and Experience Beyond 15GB, then data runs at up to 256Kbps. Essentials includes texting but no data. A photo message runs 2 MB to 4 MB, about two minutes at 256Kbps, so it drags from Grenada. A travel eSIM delivers full 4G LTE on a local network from $7.47/GB, and HelloRoam at $2.01/GB holds the lowest median 5 GB rate in the market, Nomad next at $2.30. Carrier rates checked June 2026; eSIM prices from the 30 Oct 2026 price check.
Grenada roaming bills by the day, not by the gigabyte
AT&T's per-day fee in Grenada covers 24 hours from first use. A background email sync an hour after that window closes starts a second fee, so 25 hours on the network costs $24. AT&T stops at 10 fees per line each bill cycle. Verizon runs the same 24-hour sessions with no stated cap. A travel eSIM at 1GB for $10.98 uses data-volume billing — the cost increases only when you actually consume data.
An hour of streaming in Grenada uses more data than a day of maps
An hour of Netflix in HD uses about 3 GB by Netflix's own figures, so it costs about $22.41 at $7.47/GB on FLOW. Standard definition uses about 700 MB, or $5.23. YouTube at 720p uses about 900 MB an hour. Streaming is the one habit that breaks a fixed-data plan. HelloRoam's 7-day unlimited plan has the lowest median of the five at $21.50 across 35 countries, against $27.50 on Holafly, but HelloRoam's plan runs at full speed for 2 GB a day in 33 of those 35 countries, under one HD hour. Holafly states no daily cap, which is where it earns its price for a heavy streamer. AT&T covers streaming under the $12/day pass but charges it whether you watch or not. Download over hotel WiFi and the question disappears. Carrier rates checked June 2026; eSIM prices from the 30 Oct 2026 price check.
A surprise Grenada roaming bill needs data roaming left switched on
Only if data roaming is still enabled when you land. AT&T pay-per-use rates hit $2.05/MB in Grenada — a background app sync can rack up charges before you open your phone. Even with a day pass at $12/day, a two-week trip costs $120. An eSIM at $7.47/GB eliminates bill shock — you pay a fixed amount upfront and cannot be charged more regardless of background data activity.
US carrier roaming in Grenada runs $10 to $12 a day
AT&T charges $12/day in Grenada on International Day Pass. Verizon charges $12/day on TravelPass. T-Mobile includes Grenada at a reduced speed, or $10/day on the International Pass. A 7-day trip: AT&T $84 at $12/day, Verizon $84, T-Mobile $50. A travel eSIM on FLOW at $7.47/GB costs roughly $78.44 for the same week. Rates checked June 2026.
A cruise leaving Grenada prices data differently from land travel
On land in Grenada, both options connect through local 4G LTE towers with no meaningful difference. On a cruise ship, neither carrier roaming nor a travel eSIM applies — ships use maritime satellite networks billed separately by the cruise line at $15-30/day. Buy the cruise WiFi package for onboard connectivity. Use the eSIM or carrier roaming only when the ship is docked and you are on shore.
A Caribbean regional plan against single-country Grenada coverage
Your itinerary settles it. For Grenada alone, a country-specific eSIM at $7.47/GB is the right buy. For several islands, a regional Caribbean plan holding all the stops in one data bucket usually costs less than separate eSIMs. Check the coverage list first, because the five providers draw the region differently: Airalo and Holafly each cover 200+ destinations to HelloRoam's 185, so HelloRoam, with the lowest median 5 GB rate at $2.01/GB, lists fewer destinations than those two. AT&T and Verizon charge $12/day per country, so four islands at two days each bills $96. Carrier rates checked June 2026; eSIM prices from the 30 Oct 2026 price check.
T-Mobile's free tier in Grenada sits below what maps and video need
T-Mobile's free international tier in Grenada is capped far below a usable speed. That speed supports plain text messages and basic email without attachments. It does not support Google Maps navigation, WhatsApp photo sending, or ride-hailing apps. T-Mobile's International Pass runs $10/day, under AT&T and Verizon at $12/day. A travel eSIM on FLOW at $7.47/GB delivers full 4G LTE with no speed cap.
A week of Grenada carrier roaming costs $84
AT&T: $84/week (International Day Pass at $12/day). Verizon: $84/week (TravelPass). T-Mobile: 5GB or 15GB of high-speed data included on its Experience plans, then up to 256Kbps, or $50 for a week of passes (10-day pass). The cheapest eSIM for Grenada starts at $7.47/GB on a local 4G LTE network — better per-GB value than all three carriers.
Fact check
What carriers say vs. what your bill shows in Grenada
WiFi is always available abroad, so you do not need a data plan
Hotel WiFi in Grenada covers your room. It does not cover the taxi line, the train platform, or the restaurant street. Navigation, ride-hailing, and payment QR codes all need a live cellular connection outside the hotel. A 1GB eSIM on a local network covers those gaps for $10.98. AT&T charges $12/day for the same access.
International calling cards cover data
Traditional international calling cards provide prepaid voice minutes for international calls — they do not include mobile data. Using a calling card in Grenada leaves you without data for maps, messaging apps, or anything internet-based. A 1GB eSIM on a local network at $10.98 provides data-only coverage. Pair it with a calling card if you also need voice minutes to landlines. Rates checked June 2026.
Airport SIMs are the cheapest option
Airport SIM counters in Grenada apply a tourist markup over in-city prepaid prices. Expect to queue 15–30 minutes and hand over your passport for registration. A 1GB eSIM on a local network costs $10.98 and installs from your phone before you board. Rates checked June 2026.
Our recommendation
Which eSIM to get for Grenada
HelloRoam for Grenada: HelloRoam covers Grenada on a local network and scores 9.9/10 on our rubric, the highest of the 5 providers we price. A 1GB plan costs $10.98. Unactivated plans are refundable for 180 days, and its support replies in your own language. One trade-off: Holafly is the alternative for heavy data users: it states no daily cap, at a 7-day unlimited median of $27.50 on 30 Oct 2026.
