Astaroam eSIM Data Plans for Switzerland

Astaroam does not provide a truly unlimited data eSIM for Switzerland. The plans titled “Unlimited” give 3 GB per day of high‑speed data; once that quota is reached the speed is reduced to 1000 kbps.

Travelers who need larger, predictable data allowances can choose Astaroam’s fixed plans that cover Switzerland for 30 days. Examples include a 50 GB plan, a 20 GB plan, and a 10 GB plan, all of which provide 5G connectivity and allow tethering. Selecting a fixed‑data plan may be more cost effective for users who consume large amounts 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 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.
