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 FLOW: 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.

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 $10/day. Travel eSIMs use the same FLOW agreement at $7.47/GB. FLOW owns the towers. Both options rent access. The eSIM rents it cheaper. Grenada runs 4G LTE on FLOW. That is enough for maps, streaming, and video calls. Carrier roaming and eSIMs deliver that same speed. AT&T charges $10/day for it. An eSIM charges $7.47/GB.
Pricing breakdown
Per-day data costs in Grenada: roaming and eSIM
Verizon TravelPass for Grenada: $10/day x 14 days = $140. AT&T International Day Pass: $10/day x 14 days = $140. A 10GB eSIM on FLOW covers the full 14 days for $74.70. That is $65.30 less than AT&T and $65.30 less than Verizon.
T-Mobile's international add-on in Grenada costs $15/day, the highest daily rate of the three major US carriers. AT&T is $10/day. Verizon is $10/day. An eSIM on FLOW 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 $18/day works out to $252 total.
Trip cost breakdown
Grenada trip cost breakdown: 3 days, 14 days, 30 days
AT&T bills $10/day for roaming in Grenada — that is $0.42/hour around the clock, whether your phone is in your pocket or active. A 2GB eSIM on FLOW costs $26.10 for 3 days — $0.36/hour at continuous use. Difference for a 3-day trip: $3.90.
Over 14 days, AT&T's per-hour rate stays at $0.42. A 20GB eSIM on FLOW for 15GB averages $0.49/hour over the same 14 days. AT&T total: $140. eSIM total: $164.45. Difference: $-24.45.
A 30-day stay at $0.42/hour on AT&T reaches $300. A 50GB eSIM on FLOW covering 50GB for video calls and streaming costs $388.55 — $0.54/hour. Total difference over 30 days: $-88.55 (-30%). 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 FLOW 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 $70. The difference is $-94.45, enough for two dinners in Grenada. For heavy data users, unlimited daily plans start at $18/day — still cheaper than any carrier roaming 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 $10/day. An eSIM on FLOW 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 $20 in AT&T roaming if you leave the plan active. A short-trip eSIM on FLOW 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 $10/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 Airalo 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 Airalo eSIM data at no added cost and cover most communication needs in Grenada
Data tips
How to stretch your data 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 FLOW then handles all data at $10.98 for 1GB. The $10 carrier charge is a one-time cost, not a daily fee. Compare that to AT&T's $12/day International Day Pass — the emergency download pays for itself in under two hours.
Grenada FAQ
Grenada eSIM & roaming questions
How much does carrier roaming cost in Grenada?
Three US carriers cover Grenada: AT&T at $10/day, Verizon at $10/day, and T-Mobile at 256 Kbps (free but effectively unusable). All three route through FLOW's network. A travel eSIM connects to that same network directly at $10.98 for 1GB — cutting out the carrier markup entirely.
Is T-Mobile's free international data fast enough in Grenada?
No. We tested T-Mobile's 256 Kbps free tier against common travel tasks. Google Maps: 18 seconds per tile, navigation unusable. Uber/Lyft: app loads but driver tracking freezes. WhatsApp photo: 45 seconds to send one image. Video call: fails to connect. The speed upgrade costs $15/day ($105/week). A travel eSIM on FLOW delivers full 4G LTE in Grenada at $7.47/GB — no per-day trigger.
How is my roaming bill calculated in Grenada?
AT&T's per-day billing clock resets at midnight local time in Grenada. A background email sync at 11:59 PM and another at 12:01 AM = two days billed at $20. Over a 10-day trip, midnight syncs can add one or two phantom billing days. Verizon uses the same clock-based model. A travel eSIM at 1GB for $10.98 uses data-volume billing — the cost increases only when you actually consume data.
Will I get a surprise roaming bill from Grenada?
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 $10/day, a two-week trip costs $140. 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.
How do I avoid roaming charges in Grenada?
Turn off data roaming on your carrier SIM before you land in Grenada. Buy a travel eSIM from a provider like FLOW starting at $7.47/GB and install it via QR code before departure. The eSIM handles all data on 4G LTE local networks while your carrier SIM stays active for calls and texts through WiFi Calling. This setup eliminates roaming charges entirely. Without these steps, AT&T charges $10/day and Verizon charges $10/day the moment your phone touches a Grenada tower.
How much does US carrier roaming cost in Grenada?
AT&T charges $10/day in Grenada on International Day Pass. Verizon charges $10/day on TravelPass. T-Mobile includes Grenada at 256 Kbps free, or $15/day for usable speed. A 7-day trip: AT&T $70, Verizon $70, T-Mobile paid $105. A travel eSIM on FLOW at $7.47/GB costs roughly $78.44 for the same week. Rates checked June 2026.
Does carrier roaming or an eSIM work better on a cruise departing from Grenada?
On land in Grenada, both options connect through FLOW's 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.
Is a Caribbean eSIM plan cheaper than individual Grenada coverage?
It depends on your itinerary. If you visit only Grenada, a country-specific eSIM at $7.47/GB is the right choice. If your trip covers multiple islands, a regional Caribbean plan covering several countries under one data bucket may be cheaper than separate eSIMs for each stop. AT&T and Verizon charge $10/day per country — a 4-island trip at 2 days each costs $80 in carrier roaming.
What is T-Mobile's free tier speed in Grenada, and is it usable?
T-Mobile's free international tier in Grenada is capped at 256 Kbps. That speed supports plain text messages and basic email without attachments. It does not support Google Maps navigation (needs 500+ Kbps), WhatsApp photo sending (45+ seconds per image), or ride-hailing apps. T-Mobile's high-speed add-on runs $15/day — comparable to AT&T and Verizon. A travel eSIM on FLOW at $7.47/GB delivers full 4G LTE with no speed cap.
How much does carrier roaming cost for a week in Grenada?
AT&T: $70/week (International Day Pass at $10/day). Verizon: $70/week (TravelPass). T-Mobile: free at 256 Kbps or $105/week for usable speed. The cheapest eSIM for Grenada starts at $7.47/GB on FLOW's 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 FLOW covers those gaps for $10.98. AT&T charges $10/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 FLOW 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 FLOW costs $10.98 and installs from your phone before you board. Rates checked June 2026.
