Your existing SIM stays active, so calls, texts and verification codes still reach you.
Choose it yourself
Pick the data and the days to suit you — from 500MB a day up to unlimited plans.
Prices you can read
Clear prices, nothing hidden. Just pick the allowance that fits.
Stay online after your data runs out
Once the day's allowance is spent you keep browsing without limit at a reduced speed (384 kbit/s).
Simple to install
No extra app — install your eSIM in one tap from the website. If you get stuck, every step is on the installation page.
Share by hotspot
Share your data with family or friends. Handy when several devices need to be online at once.
