RoameSIM eSIM Data Plans for Switzerland

RoameSIM does not provide a true unlimited high‑speed data eSIM for Switzerland. The plans marketed as “Unlimited” give a daily allowance of 3 GB; once that limit is reached the speed drops to 1 Mbps. Therefore, while the name suggests unlimited use, it is limited in data and speed after the daily cap.

RoameSIM offers fixed‑data alternatives that may be more suitable for heavy users. For example, a 20 GB plan valid 30 days costs $50.40 USD, a 50 GB plan for 30 days is $98.00 USD, and a 100 GB plan valid 180 days is $259.00 USD. These fixed plans allow unlimited high‑speed data up to the stated allowance and can be more cost‑effective for travelers who need a large data volume.

RoameSIM provides eSIM plans for Switzerland that include a phone number and SMS capability. The plans range in price from $21.00 USD for 1 GB of data with 7‑day validity to $124.60 USD for 20 GB with 365‑day validity. Each plan offers inbound and outbound voice and SMS, using a phone number with the dialing code +1. The number is not a local Swiss number, but it can be used while travelling in Switzerland. Travelers should confirm the exact features and any restrictions directly with RoameSIM before purchase.

RoameSIM offers 12 single‑country data plans and 35 multi‑country plans that include Switzerland. Plans are divided into two types: those with a fixed data cap, ranging from 200 MB to 100 GB, and those with a daily data cap that provide a set amount of data each day during the plan’s validity period. Prices across the available options span from about $2.40 up to $259.00, giving users a broad range of choices in both data quantity and cost.
