It connects to FLOW’s 4G network in Saint Lucia.

How much data can I buy for Saint Lucia?

Available data allowances are 1GB, 3GB, 5GB, 10GB and 20GB.

Can I top up my Saint Lucia eSIM?

Yes, you can top up the eSIM if you need more data during your trip.

Saint Lucia: is an eSIM better than a local SIM?

For most travellers, yes. A local SIM in Saint Lucia 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.
