AlpineSIM eSIM Data Plans for Tonga

AlpineSIM does not provide a high‑speed data plan that is truly unlimited for travelers in Tonga.

All of its Tonga eSIM offerings have a fixed data allowance, ranging from 1GB up to 20GB in the most generous options, and each plan expires after a set number of days. For example, the 20GB 30‑day plan costs $56.95, while a 10GB 30‑day plan is $32.29. These fixed‑data plans may be more cost‑effective than a plan that offers a capped amount of data with throttled speeds after the limit, depending on a traveler’s usage.

AlpineSIM does not provide a Tonga eSIM that includes a phone number or SMS capability. The only plans offered for Tonga are data‑only eSIMs, which give you high‑speed internet access for a set validity period but no built‑in voice or text messaging service.

Travelers who need to stay in touch can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain apps, so it is advisable to confirm that the messaging services you rely on are accessible in Tonga before purchasing a plan.

AlpineSIM provides 46 single‑country data plans for Tonga; no multi‑country plans are available. The catalogue includes both daily data‑cap options—35 plans that allow a separate daily limit—and fixed data‑cap options—11 plans that offer a set amount of data for the entire validity period. Prices range from $3.99 to $607.11, with data capacities spanning 1 GB to 20 GB. Validity periods run between 1 and 30 days.
