Firsty eSIM Review (2026)
Free basic data, forever. Pay only for speed.
Summary
The free-data eSIM: watch an ad, get free slow data worldwide, upgrade only when you need speed. Free ad-supported basic data (6 hours per ad view), paid high-speed from about 1 EUR/day.
Sherpa Verdict
You want a free safety net. The ad-supported tier gives slow data worldwide at no cost, and you only pay (from about 1 EUR/day) when you need real speed.
Pros
- • Genuinely free basic data tier, no time limit
- • One eSIM works in 200 destinations
- • Cheap daily upgrades when you need speed
Cons
- • Free tier is slow, fine for maps and messages only
- • Ad-supported model requires periodic ad views
