White-Label vs API eSIM Platform: 7-Factor Decision Matrix
TL;DR
If you want to sell eSIMs, you have two paths: launch a branded storefront or integrate an API into your existing platform. Both work. The right choice depends on your budget, technical resources, and how fast you need to launch. This guide breaks down both models with a decision matrix so you can pick the right one in 5 minutes.
The two models
Every eSIM business starts with a choice: do you want a ready-made storefront, or do you want to build the experience yourself? Here is what each model actually looks like.
Whitelabel Storefront
You get a fully built, branded eSIM web store. Custom domain, payment gateway, CRM dashboard included. No coding required.
- Custom domain and branding
- Payment processing included
- QR code delivery automated
- Deploys in 48 hours
API Integration
You get API endpoints and build the customer-facing experience yourself. Full control over UI/UX. Self-service API keys.
- Complete UI/UX control
- Embed in existing platforms
- REST API with full documentation
- Live in 3-7 days
Both models give you access to the same underlying network: BICS wholesale connectivity across 200+ countries and 350+ operators. The difference is in how you package and deliver the experience to your customers.
Decision matrix
Here is a side-by-side comparison across the factors that matter most when choosing a platform model.
| Factor | Whitelabel | API |
|---|---|---|
| Budget | €500 setup + €500 deposit | Free (pay per activation) |
| Technical skills | None required | Developer needed |
| Time to market | 48 hours | 3–7 days |
| Branding control | Full (your domain, logo) | Full (you build the UI) |
| Margin control | 100% above wholesale | 100% above wholesale |
| Maintenance | We handle everything | You maintain your code |
| Scalability | Up to ~1,000/month comfortably | Unlimited - scales with your infrastructure |
| Best for | Travel agencies, tour operators, non-technical teams | Developers, existing platforms, custom UX needs |
When to choose whitelabel
The whitelabel storefront is the right choice if most of these apply to you:
- You don't have developers on your team
- You want to launch this week
- You want payment processing, CRM, and QR delivery included out of the box
- You're a travel agency, tour operator, or reseller
- You want someone else to handle hosting, updates, and infrastructure

When to choose API
The API model is the right choice if most of these apply to you:
- You have a dev team or technical co-founder
- You want eSIM purchasing embedded in your existing app or website
- You want complete control over the UI and customer experience
- You're building a custom travel platform, super-app, or neobank with travel features
- You want zero upfront cost and only pay when customers activate

What about Telkor?
Coming April 2026
Telkor is for a different category entirely. If you are an MVNO, MNO, or enterprise that needs per-MB billing, IMSI management, and carrier-grade SLAs, Telkor is the infrastructure layer.
It is not a storefront and not a simple API. It is full telco infrastructure - designed for operators who want to build and manage their own mobile connectivity products at scale.
What is per-MB billing?
Most eSIM platforms sell fixed data packages - 1GB, 3GB, 5GB. If a traveler buys 3GB but uses only 1.8GB, they waste 1.2GB. That unused data is called "data breakage." Industry data breakage averages 25–35%.
Per-megabyte (per-MB) billing charges customers only for data they actually consume. A traveler who uses 1.8GB pays for exactly 1.8GB - no rounding, no waste.
Why it matters for resellers
- Lower effective cost per consumed GB - more competitive retail pricing
- Better customer value - higher satisfaction, fewer support tickets
- Real-time usage tracking - accurate billing, no overage surprises
Which Omax products support per-MB?
| Product | Billing model |
|---|---|
| Bappy API | Package-based (fixed packages, not per-MB) |
| Telkor API (April 2026) | True per-MB billing from €0.0005/MB |
| Whitelabel Store | Package-based (same as Bappy) |
Per-MB is ideal for MVNO operators and high-volume resellers. For most travel businesses, package-based pricing (Bappy/Whitelabel) is simpler and sufficient.
Scalability: when to switch models
Your ideal platform model depends on where you are today - and where you are heading. Here is a volume-based guide.
| Volume | Recommended model | Why |
|---|---|---|
| 0–100/month | Whitelabel Store | No dev needed, live in 48h |
| 100–500/month | Whitelabel + consider API | Store handles UX, API for integrations |
| 500–1,000/month | Add Bappy API | Embed eSIM in your existing platform |
| 1,000+/month | Whitelabel + API + consider Telkor | Multi-channel, per-MB for cost optimization |
Migration path
Start with Whitelabel. Add API later.
Most partners follow this path. You don't have to choose one forever. The store and API share the same account, same wholesale rates, same customer data.
- 1 Month 1: Launch whitelabel store (48h, €500 setup)
- 2 Month 3–6: Integrate Bappy API into your existing app/website
- 3 Month 6+: Run both - storefront for direct traffic, API for embedded purchases
- 4 2026+: Evaluate Telkor for per-MB pricing at scale
Quick recommendation
Not sure where to start?
Start with Whitelabel. It is €500, live in 48 hours, and you can always add API access later. Most partners start with the storefront and add API integration as they scale.

Frequently asked questions
What is the difference between a whitelabel eSIM platform and an eSIM API?
A whitelabel platform gives you a fully built, branded storefront with payment processing, CRM, and QR code delivery included. No coding required. An API gives you endpoints to integrate eSIM provisioning into your own app or website - you build the customer-facing experience yourself. Both models offer 100% margin control above wholesale rates.
How much does it cost to start selling eSIMs with each model?
The whitelabel platform costs €500 setup + €500 deposit with zero monthly fees. The Bappy API has zero setup fees and zero monthly fees - you only pay per activation at wholesale rates. Both models give you 100% margin control above the wholesale cost.
Can I switch from whitelabel to API or use both?
Yes. Many partners start with the whitelabel storefront to launch quickly, then add API access as they scale or want to embed eSIM purchasing into their own platform. The two models are complementary, not mutually exclusive.
Pricing and timelines are based on OmaxTelecom's offering as of March 2026. Whitelabel setup fee is €500 + €500 refundable deposit. API access is free with pay-per-activation pricing. Coverage across 200+ countries and 350+ operators is provided via BICS wholesale connectivity. Telkor launch date is subject to change.
