How eSIM APIs work

Provisioning: API requests generate a unique eSIM profile (QR code or SM‑DP+ address).
Delivery: QR code or activation code sent to user via email/app; scan to install.
Management: Check usage, top‑up data, or suspend lines via API.
Network routing: The provider's carrier agreements ensure local connectivity.

Choosing the right provider

Coverage depth: not just countries, but carrier quality and regional plans.
Pricing & margins: wholesale rates, volume discounts, and hidden fees.
API reliability: uptime, documentation, and support responsiveness.
Compliance: data privacy, local regulations (KYC if required).
Flexibility: custom plans, auto‑recharge, and white‑label capabilities.
