Astaroam eSIM Data Plans for Switzerland

Astaroam does not offer a truly unlimited high‑speed eSIM for Switzerland. The plans labelled “Unlimited” actually provide a daily data allocation of 3 GB (or 1 GB for the one‑day option) and after the allotted data is used the speed drops to 1000 kbps, so they are not unlimited in the sense of unlimited data volume.

Travelers who need large amounts of high‑speed data can choose one of Astaroam’s fixed data plans that offer a generous data allowance for a set period. For example, the Switzerland 50GB 30Days plan provides 50 GB of high‑speed data for 30 days, while the Switzerland 20GB 30Days plan offers 20 GB for the same duration. These packages may be more cost‑effective for users who consume a lot of data.

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 provides a total of 31 data plans that can be used in Switzerland. Among these, 14 are single‑country plans that cover only Switzerland, while 17 are multi‑country plans that include Switzerland as part of a larger coverage area. The plans vary from 1 GB to 50 GB of data, with prices ranging from about $0.69 up to $24.57, and validity periods from one day to 30 days. Fixed‑data plans and daily‑capped options are both available, allowing travelers to choose between a set amount of data for the whole period or a daily data limit that resets each day.
