about reselling eSIMs.

Answers to the most common questions about the eSIM.tech reseller platform.

How do I become a travel eSIM reseller?
Contact us via the contact form with your use case and receive API credentials. Once approved, call our REST API to provision eSIMs in 190+ countries. The API returns a QR code and ICCID in ~120ms, which you deliver to your end customers under your own brand. No minimum orders, no contracts.
What is an eSIM reseller platform?
An eSIM reseller platform lets companies sell eSIMs to their customers without owning carrier infrastructure. eSIM.tech provides the API, network agreements, and provisioning backend. You handle the customer relationship and set your own pricing — the product appears under your brand.
Can I white-label eSIMs for my app?
Yes. Your end customers see your brand only. The QR code and eSIM profile are delivered through your platform. eSIM.tech operates as the invisible infrastructure layer behind your product.
What countries are supported?
Pay-as-you-go data eSIMs cover 190+ countries worldwide. Local eSIMs with real phone numbers are available in 25+ countries including Germany, Netherlands, UK, USA, Japan, South Korea, and Australia. EU Data SIMs work across all 27 EU member states.
Is there a minimum order?
No. There are no minimum orders and no contracts. You are billed only for what you provision, making it easy to start with a single customer and scale from there.
What is the difference between a local eSIM and a pay-as-you-go eSIM?
A local eSIM includes a real local phone number with voice, SMS, and data — it behaves exactly like a local SIM card. A pay-as-you-go eSIM is data-only, billed per MB, covering 190+ countries — best when you only need global data without a local number.
How fast is eSIM provisioning?
The average end-to-end provisioning latency is approximately 120ms. The API returns the QR code (base64 PNG) and ICCID in the same response, so your customers can install their eSIM immediately after purchase.
Who is eSIM.tech for?
eSIM.tech is built for travel app developers, telecom resellers, MVNOs, IoT and fleet companies, and businesses needing secure connectivity for employees abroad. If you need to provision eSIMs programmatically and resell them under your own brand, eSIM.tech is your infrastructure layer.
