 Building eSIM In House vs Using a White Label Partner  
 Deciding to build eSIM in house vs white label depends on how much telecom work you want to own. Building means carrier agreements, eSIM profiles, provisioning and support in every market. A white label partner like ZIM provides all of it under your brand.

## What does building in house involve?

Negotiating with operators market by market, managing eSIM profiles and provisioning, and running network quality and support.

## What does a white label partner provide?

ZIM holds the carrier deals across 200+ destinations and 400+ networks, and runs provisioning and Level 2 support. You choose the API and MCP, a hosted web store or a branded app, and keep pricing and margins.
