To avoid confusion, we highly recommend labeling your new eSIM plan. Go to Settings > Cellular > [Your Spark Roam eSIM] > Cellular Plan Label and rename it to "Spark Roam". This ensures you always know which line is providing your high-speed travel data.
We recommend installing your eSIM the day before you travel or while you have a stable Wi-Fi connection at the airport.

Yes, Spark Roam fully supports tethering/hotspots. You can share your high-speed connection with your laptop, tablet, or family members' devices without any additional fees or restrictions.
We offer refunds if there is a verified technical failure of the eSIM that our support team cannot resolve. Because eSIMs are digital products, plans that have been activated or partially used are non-refundable.
