Cellesim is a travel eSIM service for people who want data the moment they land, without hunting for a shop or paying roaming rates.We cover more than 200 countries and regions, with local, regional and global plans. You buy online or in our app, receive the eSIM within a minute, and install it by scanning a QR code. Your physical SIM stays in the phone, so you keep your own number for calls and bank verification codes while your data runs on our line. Our plans are data only.Our iOS and Android apps let you buy, install, check how much data is left, and top up while you are abroad, without opening a browser. Running low on a trip is a two tap fix.We work in 31 languages, and support answers in the language you write in. Every destination page lists the local networks we connect to, so you can see the coverage before you buy, and our device checker tells you whether your phone supports eSIM at all.Returning customers earn loyalty credit, and referrals give both sides a discount. Selected plans include a free VPN.If something does not work, write to us. We would rather fix it or refund it than leave you offline.

All of my dealing with Cellesim have been very good when I was discussing my needs with the team. Installing my eSim was easy and no trouble.

I setup an e-sim with the instructions that Cellesim provided while we were on a trip to London. It was simple to do because the directions were very clear and easy to understand. We will use Cellesim during our next trip.
