Installed our eSIM even BEFORE our trip

July 17, 2025

Travelling from Canada we were able to install and activate the USA eSIM and get it working even before we left Canada! We were careful not to burn any data and when we landed in the USA the eSIM just worked. Cool!

Our eSIM Tips for first time users

Just get the data that you need. You can get another eSim if you run low 24 hours a day.
Purchase your eSim before you travel. Have your codes or QR code handy to activate just before you arrive. Don't worry your eSIM only starts on activation.
Turn on Low Data Mode for all your installed eSIM networks. Data savings can be as much as 80%.
At the end of the day, when you are returning to your accomodation, turn off your eSIM. Ensure that you are using the available wi-fi services. Be careful though as public wi-fi can have some risks.
To stay in contact with friends and family utilize apps like WhatsApp, Telegram and Signal.
Before you travel, download content for offline use. Netflix and Spotify allow you to do this.
Google Chrome has a data saver feature that can reduce data usage by up to 50%. Disable auto-play videos in Facebook, Instagram and other apps.
