eSIM with crypto payments150+ countries

How Aifory simplified its eSIM catalog for crypto payments

The service added automatic operator detection by phone number before payment through GiftAPI.

What did not work before GiftAPI

Customers selected their operator from a dropdown before payment. Number portability and similar operator names across countries often caused them to choose the wrong operator.

12% of orders went to the wrong operator

The payment was charged, but the subscriber received nothing because the wrong operator had been selected.

Support workload

Every disputed case required manual investigation and a refund.

Loss of customer trust

Failed top-ups reduced repeat purchases.

How GiftAPI solved these problems

GiftAPI added automatic operator detection by phone number before payment, so customers no longer need to select an operator manually from a list.

Endpoints used

POST

/telecom/lookup

Operator detection by phone number

GET

/telecom/products

Only products relevant to the operator

POST

/telecom/topup

Top-up with an idempotency key

How the integration went

Week 1

Added operator lookup before the selection form in the sandbox.

Week 2

A/B tested the new payment form on a portion of traffic.

Week 3

Fully switched payments to automatic operator detection.

What changed after the migration

Failed top-ups dropped to 0.3%

The operator is detected automatically, so customers can no longer select the wrong one.

Fewer support requests

Disputes caused by incorrect operator selection have almost disappeared.

More repeat purchases

Confidence in successful top-ups restored customer trust.

Aifory Head of Operations

“Incorrect top-ups dropped almost to zero in the very first month. A third of our support requests used to be about ‘the payment was charged, but the balance was not topped up’ — now that category has almost disappeared.”

— Head of Operations at Aifory
