What does an eSIM Reunion plan cost?
All the figures here come from Airalo, and only from Airalo. We have priced Airalo only for Reunion. We have not priced Saily, Holafly, Nomad, eSIMCard or eSIM Go here, so this is one seller's list, not a survey of the market and not a claim about the best eSIM across sellers. Seventeen Airalo plans, each read off airalo.com on 8 October 2026 and priced in US dollars, make up the eSIM Reunion list in our data. Airalo sells them under the name Reunion Mobile, its own retail label and not a mobile network.
The cheapest gigabyte is $1.65, from the 20 GB plan over 15 days at $33. The dearest is $4, from the 1 GB plan over 3 days. That is a 2.4-fold spread. Nothing capped goes above 20 GB.

Which size eSIM Reunion plan should I buy?
The rate drops steadily and then levels off. 3 GB runs $2.83 to $3 a gigabyte, 5 GB $2.50 to $2.70, 10 GB $2.15 to $2.25, and 20 GB $1.65 to $1.70. Going from 5 GB over 7 days ($12.50) to 10 GB over 7 days ($21.50) costs $9 for double the data. Moving up to 20 GB over 15 days ($33) adds ten gigabytes for $11 more than the 10 GB fortnight at $22.
Duration is nearly free to change. At 20 GB, 15 days is $33 and 30 days is $34. A month-long stay should buy the 30-day plan for $1 more.
The uncapped plans are costly against that. The 10-day uncapped plan is $35, $2 above the 20 GB fortnight, and the 30-day uncapped plan is $73.50, more than double the 20 GB month.
A weekend. 3 GB over 3 days at $8.50.
A week. 10 GB over 7 days at $21.50, or 5 GB at $12.50.
A fortnight or month. 20 GB over 15 days at $33, or over 30 days at $34.
What we do not know
Airalo publishes no host network in our data for Reunion: the network field is empty on every plan. We cannot name the carrier behind these plans and will not infer one from the product name. We have not found a public regulator or operator page we could read on Reunion SIMs, so this page says nothing about local networks, registration or prices. We also have no source on whether Reunion is covered by plans from elsewhere in France or by EU roaming, so we will not guess. An eSIM Reunion plan from Airalo is the only thing priced here; a Reunion travel SIM from a local shop is not. We have not tested these plans on a phone on the island.
For how this compares with other sellers and countries, see Airalo, the cheapest eSIM plans, the provider comparison, the Africa guide and how we test.
Common questions
What is the cheapest eSIM Reunion plan?
The 20 GB plan over 15 days at $33, which is $1.65 a gigabyte, the lowest rate among seventeen Airalo plans we verified on 8 October 2026. We have not priced any other seller for Reunion, so this is the floor of one list only.
How much is a Reunion data plan for a week?
Airalo's 10 GB plan over 7 days costs $21.50, or $2.15 a gigabyte, and its 5 GB week costs $12.50. The 3 GB week is $9. Prices were read on 8 October 2026 and can change, so check the checkout before you pay.
Does Airalo sell an unlimited eSIM for Reunion?
Yes, in six durations: $11.50 for 3 days, $20.50 for 5, $27.50 for 7, $35 for 10, $49 for 15 and $73.50 for 30. The 20 GB plans, at $33 and $34, are much cheaper unless you need uncapped data.
Is a 30-day Reunion eSIM much dearer than a 15-day one?
No. At 20 GB it is $34 against $33, and at 10 GB $22.50 against $22. In our 8 October 2026 data, a long stay barely costs more than a short one, so buy the window that covers your trip.
Which network does the Reunion eSIM use?
We do not know. Airalo's listing names the product Reunion Mobile and no host network. We have not found a public operator page we could read, so we will not name a carrier. Ask Airalo before relying on coverage outside towns.
