How to Start an eSIM Business
An eSIM business sells digital cellular data plans through a branded storefront. Customers buy a plan for the country they need, get an instant activation QR code, and connect to local carriers — no physical SIM card needed.
Step 1: Sign up with an eSIM wholesale provider
Choose a white-label eSIM provider with global carrier coverage. ResellPortal offers 200+ country coverage at $29/month.
Step 2: Pick a brand name
Travel-focused, business-focused, or general-purpose branding all work. Most successful eSIM brands have short, travel-evocative names.
Step 3: Build your branded storefront
Upload your logo, set colors, and configure the customer flow. Customers should be able to browse plans by country and check out in under 2 minutes.
Step 4: Set retail pricing on data plans
Wholesale rates vary by country. Common retail markups are 30% to 100% over wholesale. Bundle multi-country plans for higher margins.
Step 5: Integrate payment and instant delivery
Customers receive their activation QR code by email immediately after payment. Payment confirmation must trigger QR delivery within seconds.
Step 6: Target travelers and frequent flyers
Travel blogs, expat forums, and digital nomad communities are the fastest channels. Run search ads on "eSIM [country name]" keywords.
