Yesim Review: Flexible Travel Data and a Global Option

Yesim is a travel eSIM covering 150+ destinations, notable for flexible plan formats — per-country and regional data alongside pay-as-you-go and a global option. That flexibility makes it a genuine alternative to the bigger marketplaces, especially for travellers whose usage is hard to predict. This review looks at how it works and who it suits. For the full comparison, see the best travel eSIMs in 2026.

What you get

• Per-country and regional plans across 150+ destinations, plus pay-as-you-go and a global plan.
• A global option for frequent, multi-country travellers who want one plan to fall back on.
• A capable app with instant install — buy before you fly, switch on when you land.
• Your home number and messaging apps stay active alongside the data plan.

Who it suits

Yesim is worth a look if you value flexibility over the very broadest coverage. The pay-as-you-go and global formats suit travellers whose data needs vary trip to trip, or who visit several countries in quick succession and would rather not buy a new plan each time. For sheer country coverage, Airalo remains broader — so compare the exact plan you need for your destination in Airalo vs Yesim.

Setting it up

Setup follows the usual eSIM routine: buy your plan in the app, install the eSIM when prompted, and turn it on when you arrive. Install before you fly, while you still have your home connection. New to eSIMs? Our what-is-an-eSIM guide covers compatibility and installation step by step.
