The story

ByteSIM was founded in Hong Kong by Sunny Wong and Wilming Chou to provide instant 5G eSIM connectivity across 200+ countries for international travelers. As the company expanded into the US, Europe, and Asia, it outgrew its legacy local Hong Kong acquiring partner and migrated to Stripe for global payment processing, reducing its dispute rate to 0.02% and improving cross-border transaction success rates significantly.
