👍 What we like

✓203 countries with local plans, plus 13 regional and global bundles

✓Global+ plans include a phone number with voice calls and SMS — rare for a travel eSIM

✓Tethering and top-ups available on every plan in the catalogue

✓Plans from $1.99, and validity from 3 days up to a year

✓Prices published in 11 currencies

✓Unlimited plans slow down rather than cut off — around 1 Mbps after the daily cap

👎 Worth noting

–"Unlimited" means 3GB per day at full speed, then throttled to about 1 Mbps — not uncapped data

–Most plans are data-only; voice and SMS are limited to the Global+ line

–A smaller, newer brand than Airalo or Holafly, with less independent review coverage

–USD prices are shown excluding VAT, so EU buyers will see VAT added at checkout
