Why EPICeSIM

We built EPICeSIM because we experienced the problem ourselves. Arriving in a new country only to face extortionate roaming charges, finding SIM kiosks closed, or downloading apps that barely work on spotty Wi-Fi. The existing options were not good enough.

Our approach is different:

No app required
Purchase, install, and manage your eSIM entirely through your browser and email.
Genuine tools
Our Balance Checker and Refresh eSIM tool let you monitor data and fix connectivity issues yourself.
Plans from $2.79
Affordable data in 195+ countries, with no hidden fees or overage charges.
Real support
24/7 WhatsApp support with human agents, not chatbots.

Our Technology

EPICeSIM is built on WordPress and WooCommerce, integrated with enterprise-grade eSIM provisioning via the eSIM Go platform. Our infrastructure runs on Rocket.net’s global edge network with Cloudflare CDN, delivering fast page loads and reliable checkout from anywhere in the world. Redis object caching ensures sub-second server response times, and our carrier partnerships span 400+ networks across all major continents.
