What a Mawig eSIM costs
The cheapest published plan on the Marie-Galante travel eSIM is $4.50 for 1 GB valid 7 days. A 2 GB / 15 day plan is $7.65, a 3 GB / 30 day plan is $10.35, and a 5 GB / 30 day plan is $14.85. Larger buckets go up to 20 GB for 30 days at $37.40. Unlimited data is listed separately on the same product, from $17.10 for 3 days. Buy the size that matches the trip, not a larger plan “just in case”.
Network
The plan is sold under the operator name Mawig and the supported country is Marie-Galante. The product page publishes the speed as 4G. That is the figure to plan around. It is not a 5G product, and speed on the ground still depends on the mast, the handset, and the carrier Fair Usage Policy. Marie-Galante is covered as its own area on this plan, with the coverage code GP-MG, including Grand-Bourg, Capesterre, and Saint-Louis. The island is about 158 square kilometres, so one mast covers most of the ring road, though signal thins out on the quiet northern coast. Treat this as the island’s plan: it does not cover the rest of Guadeloupe, so Grande-Terre, Basse-Terre, and Les Saintes need their own plan, and it does not cover Dominica either.
How much data you actually need
Maps, chat, and ferry timetables sit inside 1 GB for a short stay. Photos and short video push a beach week toward 2 or 3 GB. A longer stay with guesthouse Wi-Fi plus mobile backup is the 5 GB or 10 GB / 30 day plan. Hotspot use burns the allowance faster than the phone alone.
Unlimited data
Unlimited plans are listed on the same product page, from $17.10 for 3 days, $22.95 for 5 days, $27.20 for 7 days, $29.75 for 10 days, $49.00 for 15 days and $84.15 for 30 days. Unlimited still sits under a Fair Usage Policy, so a hotspot left on all day can be slowed. Note that 20 GB for 30 days costs $37.40, which is less than the 15 day unlimited plan at $49.00, so a data bucket is usually the cheaper way to cover a longer stay on this island.
Dual SIM
Keep your home SIM for calls and bank texts. Turn on data roaming only for the Mawig line. iPhone: Settings, Mobile Data, pick the travel line. Android: Settings, Network, SIMs, set mobile data to the travel eSIM. Do this before you leave the Wi-Fi.
Arrival and transit
Marie-Galante has no international airport. Visitors arrive by ferry from Pointe-à-Pitre or Basse-Terre in Guadeloupe, landing at Grand-Bourg or Saint-Louis, and there is a small airfield at Grand-Bourg for light aircraft. Install the eSIM on hotel or home Wi-Fi before you travel, then switch the data line on when the ferry docks. You do not need a local shop or a passport photo for this plan.
Install
- Buy the plan and open the QR code in the order email while you still have Wi-Fi.
- On the phone, add an eSIM and scan that code. Label the line “Marie-Galante”.
- After arriving, set mobile data to that line and leave your home number on for texts.
Phone compatibility
The phone must be carrier-unlocked and eSIM-capable. iPhone XS and later, and recent Samsung Galaxy and Google Pixel models, qualify. A locked handset will not take the QR code. Check the lock status with your home carrier before you pay.
FAQ
Q1: How much is the cheapest Marie-Galante eSIM?
$4.50 for 1 GB, valid 7 days, on the Mawig plan.
Q2: Which operator is on the plan?
Mawig. The supported area is Marie-Galante.
Q3: Does it include calls and SMS?
No. It is a data plan. Keep your home SIM for calls and one-time passwords.
Q4: Is it 5G?
No. The product page lists the speed as 4G, not 5G. Real speed still depends on coverage and the Fair Usage Policy.
Q5: Can I install it after I arrive?
Yes, if you can reach Wi-Fi. Installing before you travel is simpler, because the QR download needs a connection.
Q6: Does it cover Guadeloupe?
No. This plan is for Marie-Galante, with the coverage code GP-MG. The rest of Guadeloupe and Les Saintes need their own plan, and so does Dominica.
Q7: Is there an unlimited option?
Yes. Unlimited plans are listed separately on the same product page, from $17.10 for 3 days.
Q8: Can I share it as a hotspot?
Yes, within the data allowance. Hotspot traffic counts against the same gigabytes, and heavy sharing can hit the Fair Usage Policy.
Q9: What if the QR code fails?
Use the manual activation code in the same email. The phone still has to be unlocked.
Q10: When were these prices checked?
October 2026, against the published variation prices on travelydata.com.
Bottom line
For a week on Marie-Galante, the $4.50 / 1 GB Mawig plan is the one to start with. Step up to 3 GB or 5 GB for a longer stay, or 20 GB for a month, which costs less than the 15 day unlimited plan at $49.00. The published speed is 4G.
