Cheapest eSIM for Cayman Islands: the numbers
As of 31 August 2026, 15:21 GMT, the cheapest eSIM for Cayman Islands is GigSky with 100 GB for 180 Days at $179.99. That is $1.80 per GB, the best rate of the 101 plans we compare from 9 providers. 45 plans include 5G. 33 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which mobile networks does Cayman Islands have?
Flow advertises 100% 4G LTE coverage across the three islands, while Digicel claims 99% but with a more limited real world footprint on Cayman Brac and Little Cayman.
- Flow: Flow, run by Cable & Wireless under Liberty Latin America, is the incumbent with about half the market, advertises 100% 4G coverage, and launched the Caribbean's first 5G network in June 2024.
- Digicel: Digicel arrived in 2006 to break the old monopoly, holds roughly the other half of the market, claims 99% coverage though its map is thinner than Flow's, and generally prices lower.
There are no MVNOs, and many locals simply carry both a Flow and a Digicel SIM, which tells you the two networks each have gaps.
The eSIM plans we compare on this page connect to:
Is 5G available in Cayman Islands?
Flow switched on 5G in June 2024, making the Cayman Islands the first territory in the Caribbean with a live 5G network, and the rollout is continuing from Grand Cayman outward.
How much data do you need in Cayman Islands?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Cayman Islands right now:
Are unlimited eSIMs for Cayman Islands really unlimited?
Not always. 16 of the plans above are sold as unlimited. Most unlimited travel plans have a fair use rule. You get full speed for a daily amount, often 1 to 5 GB, then the speed drops to around 1 Mbps until the next day. That is fine for messages and maps but slow for video. If you know how much data you use, a fixed plan with a low price per GB is usually the better deal. That is why we rank by price per GB and not by labels.
eSIM or a local SIM at the airport in Cayman Islands?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Cayman Islands starts at $179.99 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Cayman Islands eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in Cayman Islands
There is no documented SIM counter at Owen Roberts International Airport, so plan on visiting a Flow or Digicel store in George Town or Camana Bay. A Flow prepaid SIM costs KY$8.99 including KY$5 of credit.
Prices are in Cayman dollars pegged at KY$1 to US$1.22, so data costs more than it first appears. Flow is the pick for coverage and 5G, Digicel for price, and unused Digicel data rolls over if you renew.
Cayman Islands Travel eSIM FAQ
Everything you need to know about using an eSIM in Cayman Islands
What is the cheapest eSIM for Cayman Islands?
Right now the cheapest option ranked by price per GB is GigSky with 100 GB for 180 Days at $179.99. That works out to $1.80 per GB. Prices change often, so the table above always shows the current order.
Which networks will my eSIM connect to in Cayman Islands?
The plans we compare connect to FLOW. The exact network depends on the plan you pick. Check the plan details before you buy if one network matters to you.
Do Cayman Islands eSIMs support 5G?
45 of the 101 plans we track for Cayman Islands include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I top up my Cayman Islands eSIM if I run out?
Yes. 33 of the 101 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
How many GB do I need for a week in Cayman Islands?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is GigSky at $24.99.
