Ringo Light does not offer an unlimited data eSIM for the Caribbean.
The only Caribbean‑available plan listed is “Ringo Light Global, 10 GB a month, monthly”, which supplies 10 GB of data each 30 days for $49.99 USD. This is a fixed data plan: the data must be used within the 30‑day period, and the plan renews monthly unless cancelled. For users who require larger amounts of data, a higher‑capacity fixed plan would be more cost‑effective than attempting to purchase an unlimited option that the provider does not currently provide.
