Astaroam eSIM Data Plans for Tonga

Astaroam does not offer a truly unlimited data plan for Tonga. The plans that carry the “Unlimited” label give 3 GB per day for the specified validity period and then throttle the speed to 1 Mbps after that daily share is used. Travelers looking for a larger data allowance can choose a fixed data plan such as the 20 GB for 30 days or the 10 GB for 30 days packages, which provide a set amount of high‑speed data without a daily cap.

Astaroam does not provide eSIM plans for Tonga that include a phone number or SMS capability. Travelers will instead receive a data-only eSIM and can use VoIP applications such as WhatsApp, Telegram, or iMessage for voice and messaging. These services generally work over the data connection, but some destinations may block or restrict access to specific VoIP apps, so users should check that the services they need are available in Tonga before purchasing.

Astaroam offers a mix of single‑country and multi‑country eSIM plans that include coverage in Tonga. There are 6 single‑country plans and 10 multi‑country plans available. The plans range in price from about $2.96 to $29.64, and the data caps vary between 1 GB and 20 GB, with validity periods from 3 to 30 days. Some plans also provide tethering support and reduced speed options.
