AeroSims eSIM Data Plans for Switzerland

AeroSims does not offer a truly unlimited data eSIM for Switzerland. The plans that carry the “Unlimited” name actually provide 5GB per day of high‑speed data; once the daily allocation is used, the speed drops to 512kbps. Travelers who need a large, uninterrupted data allowance can instead choose one of AeroSims’ fixed data plans, such as the Zurich 50 GB / 30 days plan or the Zurich 50 GB / 180 days plan, both of which give 50GB of full‑speed data for the specified validity period. These fixed plans can be more cost‑effective for most users unless they expect extremely heavy data usage.

AeroSims does not provide a Swiss eSIM that includes a local phone number or SMS functionality. All available plans from this provider for Switzerland are data‑only, without voice or text services.

Travelers who need to communicate on the go can use the data connection to run VoIP applications such as WhatsApp, Telegram or iMessage. While these services normally work through a data link, some destinations may block or limit access to particular apps, so it is wise to confirm that the services you rely on are available in Switzerland before purchasing an eSIM from AeroSims.

AeroSims provides 13 single‑country plans and 30 multi‑country plans that include coverage in Switzerland. The available plans span a price range of about $3.90 to $104, with data allowances between 3 GB and 50 GB and validity periods from 1 day up to 180 days. Some plans feature a fixed data cap, while others offer a daily data limit, giving travelers flexibility depending on how much data they expect to use each day.
