AlpineSIM eSIM Data Plans for Sri Lanka

AlpineSIM does not provide a truly unlimited‑data eSIM for Sri Lanka. All plans titled “Unlimited” in the catalog have a fixed data allowance, such as 500 MB/day or 1 GB/day, and after that limit the speed is throttled. A fixed‑data plan may be more economical if you need a large amount of high‑speed data, and AlpineSIM offers some sizable options. For example, the 10 GB/day plan is available for one day, and there is a 50 GB plan that remains valid for 180 days, both of which give you a sizable, unthrottled data allowance for your stay in Sri Lanka.

AlpineSIM does not provide eSIM plans for Sri Lanka that include a phone number or SMS capability; the provider only offers data‑only eSIMs for this destination.

Travelers can use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection to make calls and send messages, eliminating the need for a local phone number or SMS support.

AlpineSIM provides 57 single‑country data plans and 104 multi‑country plans that include Sri Lanka. The plans vary from 100 MB to 50 GB of data, with prices between $0.46 and $333.66 and validity periods ranging from 1 to 365 days. Fixed‑data‑cap plans offer a set amount of data for the entire validity, while daily‑data‑cap plans give a daily allowance up to the plan’s total data cap. A number of these packages also allow tethering.
