Your carrier's roaming rate in Cayman Islands
| Carrier | Plan | Daily Rate | 7-Day Cost |
|---|---|---|---|
| AT&T | International Day Pass | $10/day | $70 |
| Verizon | TravelPass | $10/day | $70 |

AT&T International Day Pass
AT&T's day pass in Cayman Islands activates the moment your phone connects to FLOW's network abroad — including the two minutes of background data sync when you land. A full $10 charge runs whether you use 10MB or 10GB that day.
Verizon TravelPass
In Cayman Islands, Verizon connects to FLOW towers at $10/day. An eSIM reaches the same towers from $6.31/GB.
T-Mobile Magenta (high-speed add-on)
T-Mobile caps high-speed data at a daily threshold before throttling in Cayman Islands. Once throttled, the $15/day charge continues. An eSIM at $6.31/GB delivers full-speed data up to the plan's GB ceiling with no hidden throttle.
Xfinity Mobile International Pass
Xfinity Mobile charges $10 for each calendar day your phone uses data in Cayman Islands — not each 24-hour window. Arriving after midnight and leaving before midnight the next day costs two full day-pass charges on the same trip.

Frequently asked questions
- How much does AT&T roaming cost for 10 days in Cayman Islands?
- AT&T International Day Pass charges $10/day in Cayman Islands. A 10-day trip costs $100 in roaming charges. This activates automatically when your phone connects to a local network abroad.
- Is a travel eSIM cheaper than Verizon TravelPass in Cayman Islands?
- Verizon TravelPass charges $10/day in Cayman Islands. A 10-day trip costs $100. A 20GB eSIM covers the same trip for $126.21 on the same local network — saving you -26%.
- How much data do I need for a week in Cayman Islands?
- Most travelers use 1-2 GB per day for maps, messaging, social media, and light browsing. A 7-day trip needs 7-14 GB. Video calls and streaming push usage to 3+ GB per day. Choose a 10GB or 20GB plan for heavy use.
- Can a family share one eSIM in Cayman Islands?
- One eSIM stays in one phone, but most eSIM plans allow tethering (personal hotspot). A family of 4 can share a single 10-20GB eSIM through one phone's hotspot instead of paying $10/day per person for carrier roaming.
- Does T-Mobile free data work in Cayman Islands?
- T-Mobile Magenta includes free data in Cayman Islands, but speed is capped at 256 Kbps. That is too slow for Google Maps, video calls, or uploading photos. The high-speed add-on costs $15/day.
- How much does a 30-day eSIM cost for Cayman Islands?
- A 30-day eSIM for Cayman Islands depends on data volume. Metered plans (5-20GB) typically range from $8 to $35. Unlimited daily plans run $1-2/day. Both connect to the same local network as carrier roaming at a fraction of the cost.
- How much does carrier roaming cost in Cayman Islands?
- AT&T: $10/day ($70/week). Verizon: $10/day ($70/week). T-Mobile: free but throttled to 256 Kbps; high-speed add-on costs $15/day. Travel eSIM on FLOW: $10.18 for 1GB. All four options route through the same FLOW towers in Cayman Islands. The price gap between carrier roaming and eSIM is $70 versus the eSIM rate for a 7-day trip.
- Is T-Mobile's free international data fast enough in Cayman Islands?
- No. T-Mobile's free tier in Cayman Islands runs at 256 Kbps — too slow for GPS navigation, video calls, or any app that loads images. You can send basic text messages and that is about it. The high-speed upgrade costs $15/day, matching AT&T's roaming fee. A travel eSIM on FLOW provides full 5G speeds at $6.31/GB with no daily activation triggers.
- How is my roaming bill calculated in Cayman Islands?
- Relying on hotel WiFi does not prevent roaming charges in Cayman Islands. AT&T's per-day charge fires from any background cellular contact — your phone does not need an active app, just a brief tower handshake. Per-MB billing at $2.05/MB is even more dangerous with background syncs. T-Mobile's 256 Kbps free tier sidesteps per-day billing but is too slow for apps. A travel eSIM at 1GB for $10.18 gives you full 5G and locks the total cost before you board.
- Is an eSIM worth it for Cayman Islands?
- Yes, if you use more than a few megabytes per day. AT&T charges $10/day for roaming in Cayman Islands, which totals $70 for a week. A travel eSIM on FLOW starts at $6.31/GB for the same 5G speeds. The breakeven point is day one: even a single day of eSIM data costs less than one day of carrier roaming. The eSIM connects to the same local towers your carrier uses, so speed and coverage are identical.
- Do iPads and tablets support travel eSIM in Cayman Islands?
- Yes, on supported models. Apple iPad Pro (2018 and later), iPad Air (2019 and later), and iPad mini (2019 and later) all support eSIM. Samsung Galaxy Tab S9 supports eSIM. These devices connect to FLOW's 5G network in Cayman Islands at $6.31/GB. AT&T International Day Pass covers tablets on eligible lines at $10/day per device — a second device doubles the daily roaming cost. One eSIM per device is the direct approach; tethering from a phone eSIM is the lower-cost alternative for travelers who want data on a tablet without a second day rate. Rates checked June 2026.
