GeSIM — Privacy-First eSIM Connectivity
GeSIM is Charchitron Consultancy's flagship product: a privacy-focused eSIM connectivity platform built on the Solana blockchain. It provides users with mobile data connectivity while minimizing the personal information collected during signup and use, an approach that differs from the identity-heavy onboarding common among conventional mobile carriers and eSIM resellers.
Key characteristics of the GeSIM platform include:
- Privacy by design — connectivity plans that do not require the extensive personal data collection typical of traditional telecom sign-up flows.
- Blockchain-based infrastructure — built on Solana to support fast, low-cost transactions for plan purchases and account management.
- Global eSIM access — digital SIM profiles that can be provisioned directly to compatible devices without a physical SIM card.
GeSIM is developed, maintained, and operated by Charchitron Consultancy (OPC) Private Limited. To explore the product, view supported destinations, or get started, visit gesim.xyz.
