How to enable Data Roaming
If you’re heading on an international adventure and you're using a travel eSIM, you'll want to let your travel eSIM 'roam.' This means allowing it to connect to new networks, so you always have the best connection in any location.
iPhone: Open Settings > Cellular > select your eSIM > Toggle on “Data Roaming.”
Google Pixel: Open Settings > Network & internet > SIMs > select your eSIM > Toggle on “Roaming.”
Samsung: Open Settings > Connections > Mobile networks > Toggle on “Data roaming.”
Toggling on 'roaming' is important for your eSIM to work properly, but you'll want to keep 'roaming' toggled off for your primary SIM, as you may incur substantial charges from your mobile carrier.
