Astaroam eSIM Data Plans for Switzerland

Astaroam does not provide a truly unlimited high‑speed data eSIM for Switzerland. Its plans that carry the label “Unlimited” actually deliver a fixed daily allowance of 3GB, and once this limit is reached the data speed is throttled to 1000kbps.

For travelers who need larger quantities of data, Astaroam offers several fixed‑data plans. For example, a 50GB plan that is valid for 30 days costs $21.96, while a 20GB plan for the same period is available for $11.30. There are also other fixed options such as a 10GB 30‑day plan priced at $6.73. Choosing a fixed‑data plan can be more economical unless a user requires constant, high‑speed connectivity without any data cap.

Astaroam does not offer any eSIM plan for Switzerland that includes a phone number or SMS capability. Travelers who need a local number or the ability to send text messages will find that only data‑only plans are available from this provider for Switzerland.

Those who rely on messaging or voice functions can generally use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but they should verify that these apps are accessible in Switzerland before purchasing, as some destinations have restrictions on specific services.

Astaroam offers 14 single‑country plans and 11 multi‑country plans for Switzerland. The catalog ranges from about $2.01 to $39.53 in price, with data caps between 1 GB and 50 GB over validity periods of 3 to 30 days. Some plans provide a fixed data allocation for the whole validity period, while others apply a daily data cap that resets each day.
