Does the Montserrat eSIM include calls and texts?

No. It is a data-only eSIM, so calls and messages need to use internet-based apps.

What data options are available for Montserrat?

Plans include 1GB, 3GB, 5GB and 10GB, with validity periods of 7, 15 or 30 days.

Montserrat: is an eSIM better than a local SIM?

For most travellers, yes. A local SIM in Montserrat means finding a shop once you have landed, usually with ID in hand, and it leaves you on a single carrier. An eSimHero eSIM installs before you travel, works the moment you arrive, connects across the networks we carry there, and leaves your usual number active on the same phone.
