The assessment covered all five providers (HelloRoam, Airalo, Holafly, Saily, Nomad) on Swisscom's published 5G infrastructure. The market offers 7 distinct plans with per-GB rates from $1.60 to $2.84. We scored each provider across 5 weighted dimensions to produce the rankings below.

The pricing ladder spans from 1GB at $2.84 ($2.84/GB) to 20GB at $31.99 ($1.60/GB). Best per-GB value sits at 20GB for $31.99 ($1.60/GB), our recommended tier for most Switzerland travelers. Holafly adds an unlimited daily option from $2.99/day, which suits heavy data users on trips of 5+ days. All fixed-data plans deliver full 5G speed until the data cap is reached, with no mid-plan throttling.

Switzerland Network Landscape
Switzerland has 2 mobile networks: Sunrise (5G), Salt (5G). Swisscom delivers the strongest coverage combination. All 5 providers route through these carriers.
Carrier Partnerships
Switzerland operates 2 mobile networks: Sunrise (5G), Salt (5G). Swisscom serves as the primary routing partner for travel eSIMs in this market. All five ranked providers maintain routing agreements with Swisscom. Some providers additionally route through Salt as a fallback when Swisscom's signal weakens.
Swisscom publishes 5G across Switzerland, and every ranked provider attaches to it rather than to a network of its own. Two carriers give Switzerland travelers basic redundancy. Salt supplements Swisscom's coverage in areas where the primary signal is weak.
Swisscom's 5G network handles all travel eSIM traffic in Switzerland. Provider differentiation comes from plan pricing ($1.02/GB entry), app features, and support channels rather than carrier routing choices.
