About

A wholesale platform for resellers,
not another consumer brand.

Zesimo is a wholesale eSIM platform for resellers, agencies, and operators who want to sell branded mobile data without negotiating supply contracts with telecoms. The platform aggregates multiple Tier-1 carriers under one API with wallet-based billing and zero monthly commitment.

What we do

Zesimo sits between upstream eSIM providers and the resellers who sell to end customers. We handle carrier integrations, provisioning, refunds, and webhook reliability so resellers can focus on distribution, branding, and customer support.

Why provider-neutral

Most resellers sourcing eSIMs end up tied to one upstream supplier. When that supplier has an outage in a country, sales stop. When that supplier raises wholesale prices, margins drop. When that supplier goes down for maintenance, customer support floods in.

Zesimo aggregates multiple Tier-1 carriers per country. The reseller signs one contract, integrates one API, and never sees the upstream supplier. If a carrier in a given country has an issue, traffic routes through the working alternative. Customers see the reseller's brand on the install page either way.

Who Zesimo is for

• Tour operators delivering data plans to group travellers
