eSIMCard’s plans for the British Virgin Islands that carry the word “Unlimited” are not truly unlimited. Each of those plans has a fixed high‑speed data allowance—1GB or 2GB per day—after which the speed falls to a reduced rate (500kbps for the 1GB plans and 2000kbps for the 2GB plans). The plans also include a validity of 1 to 15 days and may be used for tethering.
If a traveler needs more data without speed throttling, fixed data plans are available. For example, a 50GB plan is sold for 30 days at $194.37 USD, and a 100GB plan is offered for 180 days at $478.46 USD. These plans provide the stated high‑speed data without the reduced‑speed clause that applies to the “Unlimited”‑named plans.
