A global eSIM and SIM storefront, live across multiple markets.

The situation

A telecoms operator needed a single storefront for SIM and eSIM: purchase, activation, top-up, and billing, sold across multiple markets with different currencies, taxes, and payment habits.

[PLACEHOLDER — what existed before this platform: previous stack or manual process, and what specifically made it untenable.]

[PLACEHOLDER — the hard constraint: what makes multi-market telecom commerce difficult in this specific case — provisioning, regulatory, billing edge cases. No market names or figures that fingerprint the operator.]

The approach

[PLACEHOLDER — architecture and key decisions: how the storefront, provisioning, and billing were structured, and why.]

[PLACEHOLDER — the engineering detail worth telling: eSIM provisioning flow, payment/tax handling per market, or the integration surface with the operator's core systems.]

[PLACEHOLDER — how correctness was proven: testing approach, rollout by market, or parallel-run strategy.]

The result

The storefront is live worldwide. Purchase, activation, top-up, and billing run through one platform.

[PLACEHOLDER — what the operator can do now that they couldn't before; ongoing maintenance relationship. Round any numbers broadly or omit — see README discretion rules.]
