What a Magens Mobile eSIM costs
The cheapest published plan on the U.S. Virgin Islands travel eSIM is $4.50 for 1 GB valid 7 days. A 2 GB / 15 day plan is $7.20, a 3 GB / 30 day plan is $9.90, a 5 GB / 30 day plan is $14.40, 10 GB over 30 days is $22.10, and 20 GB over 30 days is $35.70. The 3 GB / 30 day plan is the value pick: a full month for $5.40 more than the 7 day plan and three times the data. Per gigabyte the curve improves to about $1.79 on the 20 GB bucket.
Network
The plan is sold under the operator name Magens Mobile and the supported country is the U.S. Virgin Islands. The product page publishes the speed as 5G, and real speed still depends on the mast, the handset, and the carrier Fair Usage Policy. The territory is three main islands: Saint Thomas, where Charlotte Amalie and the airport are, Saint Croix to the south, and Saint John, which is reached by ferry from Saint Thomas. Coverage follows the inhabited parts of those three, and the ferry crossings and the smaller cays sit outside the practical footprint. The distinction to get right is that the U.S. Virgin Islands and the British Virgin Islands are different countries with different plans: this one covers the U.S. islands only, so a day trip to Tortola, Virgin Gorda or Jost Van Dyke needs the British Virgin Islands plan. It also does not cover Puerto Rico or the U.S. mainland, even though all three are part of the United States.
How much data you actually need
Maps, chat, and ferry timetables sit inside 1 GB for a short stay. Beach days and boat trips are where the allowance goes, because you are often away from hotel Wi-Fi: a two-week trip across Saint Thomas, Saint John and Saint Croix with daily photo uploads is the 3 GB to 5 GB plan, and a longer stay or hotspotting is 10 GB. Download ferry schedules and offline maps before you leave Charlotte Amalie.
Unlimited data
Unlimited plans are listed on the same product page, from $17.43 for 3 days, $25.08 for 5 days, $31.03 for 7 days, $34.85 for 10 days, $50.15 for 15 days and $84.15 for 30 days. Compare them against the buckets before buying: 20 GB over 30 days costs $35.70, which is close to the 10 day unlimited plan at $34.85, and 10 GB over 30 days at $22.10 is cheaper than 5 days of unlimited. For anything longer than a short trip the buckets are the better buy. Unlimited still sits under a Fair Usage Policy, so a hotspot left running all day is exactly what gets slowed.
Dual SIM
Keep your home SIM for calls and bank texts. Turn on data roaming only for the Magens Mobile 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 Cyril E. King Airport (STT) on Saint Thomas, with Henry E. Rohlf (STX) serving Saint Croix, and ferries linking Saint Thomas to Saint John and to the British Virgin Islands. 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 “USVI”.
- 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 U.S. Virgin Islands eSIM?
$4.50 for 1 GB, valid 7 days, on the Magens Mobile plan.
Q2: Which operator is on the plan?
Magens Mobile. The supported country is the U.S. Virgin Islands.
Q3: Does it include calls and SMS?
No. It is a data plan, with voice calls only through apps such as WhatsApp or FaceTime. Keep your home SIM for calls and one-time passwords.
Q4: Is it 5G?
Yes. The product page lists the speed as 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: Will it work in the British Virgin Islands?
No. The BVI is a separate country with its own plan, so a day trip to Tortola or Jost Van Dyke needs that plan. Puerto Rico and the U.S. mainland are also outside this one.
Q7: Is there an unlimited option?
Yes. Unlimited plans are listed separately on the same product page, from $17.43 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 Saint Thomas, the $4.50 / 1 GB Magens Mobile plan is the entry point and the 3 GB / 30 day plan at $9.90 is the one most travellers should buy, especially if you are adding Saint John and Saint Croix. Take 5 GB at $14.40 for a longer stay with daily uploads, and remember that the British Virgin Islands need their own plan. The published speed is 5G and the buckets are the better value here.
