The Challenge: Moving Beyond Physical Inventory

eSimSelect needed more than a storefront; they required a real-time bridge between Australian travelers and global telecom providers. The complexity lay in the logic of selection—managing multiple provider agreements where coverage and commission margins fluctuated based on destination.

The Custom Middleware Engine

Standard Shopify apps could not handle the "Check Availability & Provision" workflow. We built a custom application that orchestrates the following flow:

  • check_circle Pre-Order Validation: Real-time ICCID and country availability check via API before payment is accepted.
  • check_circle Automated Provisioning: Post-payment, the app communicates with the 1Global (Truphone) infrastructure to generate unique eSim profiles.
  • check_circle Dynamic Fulfillment: eSim data and auto-generated QR codes are injected directly into the Shopify Order Status page and automated emails.

User Experience & Self-Service

Because technical delays can occur in telecom networks, we engineered a polling system. If an eSim isn't ready instantly, the customer is notified and can return to their order page later, where the data appears automatically once the provisioning is confirmed. We also integrated advanced self-service features:

Reloading existing plans
Plan Details lookup
Instant Cancellation logic

Expertise in the eSim & Connectivity Space

Our custom integration architecture is compatible with all major eSim aggregators and connectivity providers, including:
