Coverage & networks
Caribbean has widespread 4G/LTE coverage, with 5G in major cities and growing elsewhere. Travel eSIMs connect automatically to the strongest available local network when you arrive, so there’s nothing to configure beyond switching the line on. Coverage is strongest in urban and tourist areas; expect it to thin out in remote and rural regions.
Entry & visa rules
Most Caribbean nations are visa-free for short tourist stays for major passports — confirm per island.

Connectivity tips for Caribbean
- Public Wi-Fi is common in hotels, cafés and airports in Caribbean, but it's often slow and unsecured — a data eSIM keeps you online securely on the move.
- Turn OFF data roaming on your primary line and turn it ON only for the eSIM line, so you're never billed by your home carrier.
- Download offline maps and your translation app before you go — then your eSIM data lasts longer.
- Keep the provider's app installed so you can top up data instantly if you run low during your trip.

When should I buy and install the eSIM?
Buy it a day or two before you fly and install it over Wi-Fi at home — you'll get a QR code to scan. It won't start using data until you switch it on, so it's safe to set up early. It then connects automatically when you land in Caribbean.

Most Caribbean nations are visa-free for short tourist stays for major passports — confirm per island.
