4S eSIM eSIM Data Plans for Oceania

4S eSIM does not offer a true unlimited data eSIM for Oceania. The Oceania plans in the catalog all provide a fixed data allowance; for example, the Oceania 20GB options give 20GB of high‑speed data for validity periods ranging from 5 days to 30 days, and there is no plan listed that provides unlimited high‑speed data for this region.

While 4S eSIM does have “Unlimited”‑named plans for Asia, these come with daily data caps and a reduced speed of 1000kbps once the cap is reached. For instance, the Asia+ Unlimited MAX – 5GB/day for 5 days costs $23.95 USD and throttles to 1000kbps after 5 GB. Travelers who need a very high daily data allowance may find these Asia+ Unlimited options useful, but for Oceania the most economical choice remains a fixed‑data plan such as the 20GB packages.

4S eSIM does not provide eSIM plans for Oceania that include a phone number or SMS capability. Only data‑only eSIM options are available from this provider for the region.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. These services offer voice and messaging functions without requiring a local phone number or SMS support.

Plans such as Oceania, Asia+, Asia‑20, Global and Global139 include coverage in the Oceania region, covering Australia and New Zealand, while the Global (120 + areas) plan expands that reach to include Guam in addition to Australia and New Zealand.
