Released typo-aware email suggestions in purchase history: When an entered email does not match any results (for example a typo like .co instead of .com), the dashboard now suggests the closest known email with the prompt: "Use example@domain.com instead".
Released eSIM purchase confirmation email customization: Partners can now customize eSIM purchase confirmation emails with a primary color, secondary color, and email language, in addition to the existing email brand (subject), for better brand alignment and engagement.

Released price list update (March 1): Added Benin as a new destination, removed Georgia from Region-2 and Euro-Med, and improved pricing for the Asia region and other destinations.
Released landing page translation updates: Translation improvements are now live on landing pages.
Released 50GB packages for most destinations: 50GB plans were rolled out across most supported destinations in March.
Added iOS and Android activation links in Purchase V2 response: Purchase V2 now returns direct activation links for iOS (iosActivationLink) and Android (androidActivationLink) in the profile response to improve end-user experience and simplify eSIM installation on devices.

Released advanced network brand support: Network brand values now support additional characters such as spaces, dots (.), and ampersands (&), which enable naming combinations that were not previously possible, for example Travel Max, A&B Mobile, or Connect.Co.

Released Zapier beta integration: CELITECH is now available as a beta integration on Zapier for workflow automation. See the Zapier integration guide.
Released MCP beta integration: CELITECH now offers a beta MCP integration for AI-agent workflows. See the MCP integration guide.

Added iFrame currency customization (query param): The iFrame now supports a currency query parameter to pre‑set the pricing currency (e.g. ?currency=USD). This is case sensitive and must match one of the supported 3‑letter codes: USD, EUR, AUD, CAD, NZD, GBP, ZAR. If omitted or invalid, the default remains USD.

Added ISO2 country code support: Added ISO2 (2‑letter) country codes across all endpoints alongside existing ISO3 support. This reduces mapping effort and remains fully backward compatible with ISO3.
Released Go and C# SDKs: Official Go and C# SDKs now available with built‑in OAuth2, request helpers, and code snippets. They provide a consistent, streamlined developer experience similar to our existing JS/TS, Python, PHP, and Java SDKs. See the SDKs overview.

This dynamic iFrame provides a complete frontend solution that can be seamlessly embedded into web and mobile applications. For detailed integration instructions, refer to our iFrame Integration Guide.

Improved the purchase source feature: The source feature in the GET /purchases endpoint now supports a new possible value "promo-page" on top of the existing "API", "dashboard", and "landing-page".

- The POST /purchases/topup endpoint now accepts a new referenceId param in the body.
