What a Vaina Communications eSIM costs
The cheapest published plan on the Dominica travel eSIM is $8.00 for 1 GB valid 7 days. A 2 GB / 15 day plan is $13.00, a 3 GB / 30 day plan is $17.00, and a 5 GB / 30 day plan is $23.00. There is no unlimited plan on this product, and 5 GB is the largest bucket here. Buy the size that matches the trip, not a larger plan “just in case”.
Network
The plan is sold under the operator name Vaina Communications and the supported country is Dominica. 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. Dominica is covered as one country on this plan, including Roseau and the roads between Portsmouth and the airport. This is the island between Guadeloupe and Martinique, not the Dominican Republic. Signal thins out in the interior valleys around the Boiling Lake trail, so download offline maps before a hike. It does not cover Guadeloupe, Martinique, or Saint Lucia, so an island hop needs a plan per island.
How much data you actually need
Maps, chat, and boarding passes sit inside 1 GB for a short stay. Photos and short video push a week toward 2 or 3 GB. A longer stay with hotel Wi-Fi plus mobile backup is the 5 GB / 30 day plan, which is the largest bucket on this product. Hotspot use burns the allowance faster than the phone alone.
Unlimited data
This product does not list an unlimited plan. The largest published SKU is 5 GB for 30 days at $23.00. There is no 10 GB or 20 GB step either. If you need a daily cap removed, that is a different product, not this one.
Dual SIM
Keep your home SIM for calls and bank texts. Turn on data roaming only for the Vaina Communications 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 airport Wi-Fi.
Arrival and transit
Most visitors land at Douglas-Charles Airport (DOM) in Marigot, at the north-east end of the island, with a small strip at Canefield near Roseau. Install the eSIM on hotel or home Wi-Fi before the flight, then switch the data line on after you clear arrivals. 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 “Dominica”.
- After landing, 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 Dominica eSIM?
$8.00 for 1 GB, valid 7 days, on the Vaina Communications plan.
Q2: Which operator is on the plan?
Vaina Communications. The supported country is Dominica.
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 land?
Yes, if you can reach Wi-Fi. Installing before the flight is simpler, because the QR download needs a connection.
Q6: Is this the Dominican Republic?
No. This plan covers Dominica, the island between Guadeloupe and Martinique. The Dominican Republic is a separate country and a separate product.
Q7: Is there an unlimited option?
No. This product has no unlimited SKU. The largest plan is 5 GB for 30 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 in Dominica, the $8.00 / 1 GB Vaina Communications plan is the one to start with. Step up to 3 GB or 5 GB if you will be off hotel Wi-Fi most of the day. The published speed is 4G. There is no unlimited plan on this product.
