Cayman Islands eSIM FAQ
Yes. Cayman Islands plans connect to local mobile networks. Most iPhones since the XS and most recent Android phones have eSIM. Many models sold in mainland China, Hong Kong, Macao and Taiwan do not, and nor do some US carrier models. Dial *#06# and look for an EID, or check our compatible-phones guide.
For a 1-week trip with maps, messaging and social media: 3–5 GB. For 2+ weeks or heavy use (video calls, streaming): 10 GB+. Light users who mainly use WhatsApp and maps can get by with 1–2 GB per week.
From $11.30 for 1 GB and 7 days. Cayman Islands has 10 plans on e-sim.onl with different data amounts and validity periods. All prices are transparent with no hidden fees or activation charges.
Your QR code arrives by email right after purchase, typically within seconds. Install the eSIM before your trip; the plan starts when you first connect abroad. No physical SIM card or shipping required.
Yes. Most eSIM-compatible phones support dual SIM, so your physical SIM stays active for calls and texts while the e-sim.onl eSIM handles mobile data in Cayman Islands. You stay reachable on your home number.
If your eSIM supports top-ups, a Top up button appears in My eSIMs once the eSIM is in use. The extra data goes onto the same eSIM, usually within a few minutes. If it doesn't, buy a new plan; it arrives as a new eSIM.
All 10 Cayman Islands plans include 5G where the network and your phone support it.
