That's exactly what we did at eSIMo! eSIMo is an eSIM provider focused on travelers. Before eSIMo, no other eSIM (electronic SIM card) provider had a user experience where users could access a rewards club with a level system where you earn points for purchases, inviting friends, and visiting new countries! Users are motivated to earn points and move to new levels to get higher cashback percentages or increase the reward for inviting friends. Users don't switch to another provider because they know they will be rewarded for every action they take in eSIMo, which increases sales and trust in the product!
