Since 2019 · Singapore · ~200 countries
Most travellers. Unlimited-data plans by trip length, the widest country list, and the most polished app.
Good: Unlimited-data plans priced by number of days — no GB to track
Watch: Unlimited plans run at reduced speed after a fair-use threshold in some countries
Read the Airalo reviewSince 2018 · Spain · ~200 countries
Unlimited-data travellers who want a simple choice and don't mind paying a little more than Airalo.
Good: Genuinely unlimited data on every plan, priced purely by days
Watch: Usually the most expensive of the three on any given trip length
Read the Holafly reviewSince 2024 · UK (Nord Security) · ~200 countries
Light and budget users. Small capped-data plans from ~$3–4, far cheaper than any unlimited plan.
Good: By far the cheapest way to get online for a short or light trip
Watch: You have to estimate your data need — run out and you top up
