Fully Signal vs Saily: Building Your Own eSIM Brand vs Using a Consumer App
Saily is a consumer travel eSIM app from the team behind NordVPN, aimed at travellers who buy plans in the app. Fully Signal is a white-label wholesale platform: businesses sell eSIM data in 210+ countries under their own brand, at wholesale prices, through a panel or a REST API. Pick Saily for a personal trip; pick Fully Signal to build an eSIM product.
In this article
Saily entered the travel eSIM market with strong brand recognition from its parent company, Nord Security. For a traveller, it's a familiar name with a polished app. For a business, the question is different: do you want to send your customers to someone else's app, or offer them your own?

What consumer apps do well
Consumer apps are optimised for one person buying one plan: a slick app, a well-known brand and in-app top-ups. If you're writing a "best eSIM apps" article, they're fair recommendations.
What a business needs instead
Businesses that serve travellers — agencies, hotels, airlines, tour operators, telecoms, fintech and travel apps — usually want:
- Their own brand in front of the customer
- Control of price and packaging (bundles, loyalty perks, corporate plans)
- Integration into their existing checkout or app
- Ownership of the customer relationship and data
- Margin on every sale and top-up
That's what white-label wholesale is for. Learn what white-label eSIM means.
Security-minded businesses
Saily's parent company is known for security products, and security matters when you sell connectivity. On Fully Signal, partners get scoped API keys, IP allowlists, two-step sign-in, team roles and automatic pausing of idle keys — built for businesses that handle money and customer data.
Which one should you pick?
- You're travelling → a consumer app such as Saily is a convenient choice.
- You run a business and want your own eSIM product → Fully Signal.
- You only want to recommend an app → an affiliate link may be enough; see reseller vs affiliate for what you leave on the table.
