Astaroam eSIM Data Plans for Switzerland

Astaroam does not provide a truly unlimited data eSIM for Switzerland. The plans that carry “Unlimited” in their name actually have a hard cap of 1 GB for a single day or 3 GB per day for up to 30 days, and once that amount is reached the speed is throttled to 1000 kbps.

Travelers who need more data can choose from Astaroam’s fixed data plans, such as the 50 GB 30 days or 20 GB 30 days options, which offer high‑speed data for the full validity period. These fixed plans are generally more cost‑effective unless a user expects to consume data well beyond the capped amounts of the “Unlimited” plans.

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.
