MobileSIM eSIM Data Plans for Tonga

MobileSIM does not provide a truly unlimited high‑speed data plan for Tonga. The plans listed as “Oceania Unlimited data” give a daily allowance of 3GB; after that amount the speed is reduced to 1000 kbps, so the data is not unlimited.

For travelers who need more data without the daily cap, MobileSIM offers fixed‑data options. A 20‑GB plan for 30 days is available for $49.00 USD, along with 10‑GB and 5‑GB plans for the same period. These give a higher data allowance per validity period and may be more cost‑effective for users with heavy data needs.

MobileSIM does not offer an eSIM plan for Tonga that includes a local phone number or the ability to send or receive SMS. All eSIMs available for Tonga from MobileSIM are data‑only, providing high‑speed internet access but no telephony services. Travelers who need voice or messaging can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which can provide calls and text without requiring a traditional phone number or SMS capability.

MobileSIM offers 22 multi‑country data plans for Tonga, with no single‑country plans available. The plans vary from $2.30 to $66.00 and include data caps ranging from 200 MB up to 20 GB. Within this selection there are 4 daily data‑cap plans that reset each day and 18 fixed data‑cap plans that provide a set amount of data for the full validity period. The validity of each plan ranges from 3 to 60 days, and some plans may include a reduced speed feature after the data limit is reached.
