Astaroam eSIM Data Plans for Switzerland

Astaroam does not provide a true unlimited data eSIM for Switzerland. The plans that contain “Unlimited” in their name actually have a hard data cap—1 GB for a 1‑day plan or 3 GB per day for the multi‑day options—and after the cap the speed is reduced to 1000 kbps. For travelers who need more data without a reduction, Astaroam offers fixed‑data plans such as the Switzerland 20 GB 30 days plan or the Switzerland 50 GB 30 days plan, which provide a large amount of high‑speed data for a set period and can be more cost‑effective than the “Unlimited” style 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 14 single‑country data plans and 19 multi‑country data plans for Switzerland. The plans range in price from about $0.93 to $24.01 and offer data caps between 1 GB and 50 GB. Some plans are fixed‑data, giving a set amount of data for the validity period, while others use a daily data cap that limits usage each day. Many of the plans also allow tethering and include a reduced speed option of 1000 kbps.
