Your Cayman Islands eSIM in two questions
Which Cayman Islands eSIM plan do I need?
From George Town to Cayman Brac, your days and your phone habits pick the plan, so match them to one of these.
- A city break in George Town: For 3 days with light use, such as maps and messages, pick 1 GB for 7 days. For standard use with social media and music, pick 3 GB for 15 days.
- A fortnight touring the islands: For 14 days of standard use, visiting George Town, Cayman Brac and Little Cayman, pick 10 GB for 30 days.
- A month-long stay: For 30 days of standard use, pick 20 GB for 30 days. If you mostly use maps and messages, 10 GB for 30 days covers it.
- A trip that also takes in other Caribbean islands: The Caribbean eSIM bundle covers 25 countries, the Cayman Islands included, so one eSIM can cover your other stops.
Most plans can be topped up, and the longest plan lasts 30 days.

These eSIMs cover the Cayman Islands and more countries on one plan.
Will my eSIM have signal in the Cayman Islands?
Your eSIM joins FLOW, the Cayman Islands network, and runs on 4G rather than 5G. Your phone picks FLOW on its own, so there's no network to choose once you land. Use maps, WhatsApp and messages as you normally would, with mobile data switched on.
Daily plans slow to a fair-use speed once you've used up that day's allowance. Your data reaches the internet through Europe, which is a normal setup for travel eSIMs, and you can read more on how your IP address works abroad.
How much data do you need in the Cayman Islands?
Light: maps, messages, email (about 0.25 GB a day). Standard: plus social, music, some video (about 0.7 GB a day). Heavy: plus streaming, video calls, hotspot (about 1.8 GB a day).

Using your phone in the Cayman Islands: arrival and data tips
Landing at Owen Roberts: Install your eSIM at home on Wi-Fi, then switch it on as you touch down at Owen Roberts (GCM). Keep data roaming on for the eSIM line; the data roaming steps cover it.
Getting around: Your eSIM connects to the FLOW network on 4G, so there is no 5G to look for. Use it for maps from George Town to Seven Mile Beach, and on Cayman Brac and Little Cayman too.
Staying in touch: Message people on WhatsApp while your home number stays on for calls and texts. Here's how to keep WhatsApp and your home number working together.
Data for your trip: Light use, such as maps, messages and email, is about 0.25 GB a day. Standard use, adding social media, music and some video, is about 0.7 GB a day. On daily-allowance plans, speed drops to 512 Kbps once you pass your limit, and most plans can be topped up.
Cayman Islands eSIM questions
How much is an eSIM for the Cayman Islands?
Cayman Islands eSIMs start at £7.99 for 500 MB a day over 1 day. A 5 GB plan for 30 days costs £57.99. Prices include any taxes and show in pounds, euros or dollars.
Which networks does the Cayman Islands eSIM use?
Your eSIM connects to FLOW in the Cayman Islands. Your phone picks the strongest signal automatically.
When does my Cayman Islands eSIM start?
Most plans start the moment your eSIM first connects to a network in the Cayman Islands, so you can buy and install it at home before you fly. Install it within 180 days of buying.
Can I top up my Cayman Islands eSIM?
Yes. Most Cayman Islands plans can be topped up from your eSIM page in two taps, with no new QR code. The plan table on this page shows which ones.
Why does my IP address show another country?
Cayman Islands plans route your data through Europe, a normal setup for travel eSIMs. Websites and apps may show that country's content; your speed and coverage in the Cayman Islands are not affected.
Does it come with a phone number?
Every eSIMology plan is data only. Keep your own SIM switched on for calls and texts, and use WhatsApp, FaceTime or any calling app over your eSIM's data.
What if my plans change?
Cancel an eSIM you haven't installed within 30 days for a full refund to your card, in two taps from your eSIM page.
Is there 5G in the Cayman Islands?
No, there's no 5G in the Cayman Islands. FLOW runs a 4G network, so expect 4G, which is plenty for maps, messages and email.
Can I use WhatsApp in the Cayman Islands?
Yes. WhatsApp is the local messaging app in the Cayman Islands, and it runs over mobile data, so keep mobile data switched on to send and receive messages.
Does a Caribbean eSIM cover the Cayman Islands?
Yes. A Caribbean eSIM covers 25 countries, the Cayman Islands included. If you're island-hopping across the Caribbean, that's the one to look at.
How much data do maps and messages use on Grand Cayman?
Not much. Maps and messages are light use, so a day of directions around George Town or Seven Mile Beach won't use much of a plan.
Can I buy an eSIM for just one day in the Cayman Islands?
Yes, daily plans start at one day, so a short stop on Cayman Brac or Little Cayman doesn't need a full week of data. You pick a daily allowance that suits how much you'll use.
Can I share my phone's connection as a hotspot in the Cayman Islands?
You can share it, but hotspot use counts as heavy use in the Cayman Islands and needs far more data than maps and messages. If a laptop will rely on your phone, choose a bigger plan before you land.

Buy now, install today, and your plan waits until you land. Full refund if not installed.
