Is it worth getting an eSIM for Cayman Islands?
For most tourists and business travellers, yes, if your phone supports eSIM. Cayman Islands plans start at $5.49 for 1 GB, and you install the eSIM before you fly, so you have data when you land, without queuing for a tourist SIM at the airport. If your home plan already covers Cayman Islands at no extra cost, you may not need one.

Cayman Islands eSIMs on MobiMatter run on 2 networks: Digicel and Flow. Each plan names its network, so you can pick the one with better coverage where you are going.
Which eSIM is best for Cayman Islands?
No plan covers Cayman Islands alone right now, so the choice is a multi-country plan. The top one is 5 GB for 30 days at $22.99 from NextLink, covering 37 countries. We rank plans on quality and value for money. If price per GB is all that matters, the lowest right now is $2.80 per GB, with 25 GB for 90 days.
How much data do I need for a week in Cayman Islands?
It depends on how you use your phone. Light use (maps, messaging, browsing) takes about 0.5–1 GB a day; scrolling a lot of social video can take 2–3 GB or more. Typical use per hour:
- Instagram Reels, TikTok: 0.3–1 GB
- YouTube, Netflix at standard quality: 0.5–1 GB
- Video calls (WhatsApp, FaceTime): 0.5–1 GB
- Voice calls (WhatsApp, FaceTime Audio): 50–70 MB
- Maps and navigation: 2–6 MB
- Messaging and browsing: 50–150 MB
The cheapest Cayman Islands plan with at least 5 GB for a week or longer is 5 GB for 30 days at $21.99.
Do Cayman Islands eSIMs support 5G and hotspot?
Cayman Islands plans currently run on 4G/LTE. Hotspot (tethering) works on every plan, so you can share your data with other devices.
Does a Cayman Islands eSIM come with a phone number?
Most travel eSIMs, including most Cayman Islands plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Cayman Islands eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except most models sold in mainland China and some sold in Hong Kong and Macao.
Can I keep my own SIM and WhatsApp while using a Cayman Islands eSIM?
Yes. Your eSIM and your main SIM can be active at the same time. Use the eSIM for mobile data with data roaming on for that line, and turn data roaming off on your home SIM to avoid charges. WhatsApp keeps working on your usual number.
