To meet this demand, both platforms integrated Gohub’s eSIM API, allowing users to purchase and activate eSIMs directly within the app—in just 5 minutes. With over 7,000 eSIM products covering 190+ countries, this seamless experience not only boosts customer satisfaction but also opens up new revenue streams for MoMo and ZaloPay.

What’s an eSIM?

An eSIM is a digital SIM that’s embedded directly into a device. Instead of using a physical SIM card, users simply scan a QR code (delivered via email) to activate their mobile plan.

Key Benefits

eSIMs aren’t just for travel apps — e-wallets, digital banks, and super apps can all integrate eSIMs to grow their ecosystems.
Instant connection and activation — Travelers expect fast, hassle-free mobile connectivity.
Revenue growth and user retention — With 32 million MoMo users and 14 million ZaloPay users, Gohub’s API expands both platforms’ services and ecosystems, increases user engagement, and generates new revenue streams—helping them solidify their positions as multi-service platforms.

1. The Challenge: Scaling Digital Services Seamlessly

Expanding a digital service ecosystem offers huge potential—but it’s not without challenges. MoMo and ZaloPay knew eSIMs could add serious value, but scaling the service required overcoming a few hurdles:

Fragmented Mobile Connectivity

Users needed instant mobile data, but the traditional eSIM purchase process was multi-step and relied on external platforms.

Inefficient Manual Processes

Purchasing eSIMs previously involved manual approval, email confirmations, and slow activations—disrupting the user experience and lowering conversion rates.

The Need for an Automated, Scalable Solution

Both platforms required an easy-to-integrate API that could handle real-time eSIM orders and automate the fulfillment process.

2. The Solution: Gohub’s eSIM API Integration

By integrating Gohub’s eSIM API, MoMo and ZaloPay transformed into travel connectivity hubs, offering eSIMs directly in their apps.

Why Did MoMo & ZaloPay Choose Gohub’s API?

Thanks to this integration, MoMo and ZaloPay are now more than just payment apps—they’re mobile connectivity gateways for travelers.

3. The Implementation Process

Phase 1: API Integration & Security Setup

MoMo and ZaloPay’s technical teams partnered with Gohub to integrate the real-time API. They secured the API with Partner ID, API key, and IP whitelisting.

Phase 2: Testing & UX Optimization

Comprehensive testing ensured smooth purchasing, activation, and real-time updates. The purchase flow was streamlined from 5 steps down to 2, improving user experience.

The service then rolled out platform-wide, with ongoing improvements based on user feedback.
