Frequently asked questions
How much does a day of mobile data cost in Saint Martin?
On plans with a fixed data allowance, £0.23 to £0.57 a day in Saint Martin: 3 GB for 30 days at £6.99 is the lowest daily price, 1 GB for 7 days the highest. The plan that costs least for the whole trip: for 7 days, 1 GB at £0.57 a day; for 15 days, 2 GB at £0.47 a day; for 30 days, 3 GB at £0.23 a day. Unused days are not refunded.
Which network does the eSIM use in Saint Martin?
Only Digicel (4G): it is the single partner network for Saint Martin in the catalogue. Where Digicel has no coverage, this eSIM has no signal either, so on a remote route check that Digicel covers it.
What if the eSIM doesn't work when you land in Saint Martin?
Check, in this order: data roaming is on for the eSIM line, the eSIM is chosen as the line for mobile data, and aeroplane mode is off. The APN sets itself on this plan, so leave it as it is. Give the phone a few minutes to register on Digicel; that first registration is what starts the plan’s days. Still no connection? See what to check when the eSIM has no signal abroad.
General questions have their own pages: how card payment works, refund policy, how to install an eSIM and help and FAQ.
Prices come from our partner operator’s catalogue and may change; the amount at the moment of payment applies. We are not a mobile operator: network access is provided by the partner operator, under the plan’s terms. See the terms and the refund policy.
