Bought the wrong plan? An unused, never-activated eSIM can be refunded in full within 30 days of purchase. See our refund policy for the full terms.
Fixed data plans give you a set amount of data, for example 1 GB or 5 GB, to use at full speed for the whole plan period. When it runs out, you top up or buy again. Pick this if you know roughly how much you'll use.
Unlimited plans have no total data cap for the plan period, but each day includes a high-speed allowance. Once you use that day's allowance, you carry on at a reduced speed. Reduced-speed data has a daily limit too, and if you reach it, data pauses until the allowance resets 24 hours after you activate the eSIM. Pick this for heavier or less predictable use. A fair-use policy applies.
Pay As You Go is not a plan at all. You add credit once and it comes off by the megabyte at the local rate as you use it, so you never pay for data you do not finish. Credit never expires, data pauses when the balance hits zero, and the same eSIM keeps working across every country we cover. It costs more per gigabyte than a plan, so pick this for light or hard to predict use rather than heavy days.
Add your other stops and we check whether one regional eSIM costs less.
French law extends the end of roaming surcharges to French Guiana, so a mainland French plan works here much as it does at home, within any mobile data limit your operator sets, as Arcep explains. On a plan from another EU country, check how it treats French Guiana before you fly.
Signal fades fast once you leave the towns. Canada's travel advice says service is intermittent outside cities and absent in parts of the Amazon rainforest, and Arcep found weak mobile data even in river communes like Maripasoula and Grand-Santi.
Every arriving traveller aged one and over must show proof of yellow fever vaccination, the CDC notes, and Canada's advice says the same. Keep your vaccination certificate with your passport so it's ready when you land.
Canada also advises not relying on your phone in an emergency outside population centres. Source: Canada's travel advice.
