How Much Can You Earn Reselling eSIMs? The Margin Math Explained

Quick answer

Your earnings from reselling eSIMs equal the number of eSIMs sold times your average margin, plus top-up revenue. For example, 300 eSIMs a month at a €6 average margin is about €1,800 a month before costs; higher wholesale tiers, bundles and top-ups increase that. The real drivers are your audience size, attach rate and pricing.

"Is eSIM reselling worth it?" is one of the most common questions we hear. The answer depends on a few numbers you can estimate today. This guide shows the formula and three worked examples.

The formula

Monthly profit = (eSIMs sold × average margin) + (top-ups × top-up margin) − your costs

Where:

  • eSIMs sold = travellers you reach × the share who buy (your attach rate)
  • Average margin = average retail price − average wholesale cost
  • Costs = payment fees, marketing, support time, tools

Example 1: A travel agency

  • 1,000 travellers a month
  • 25% attach rate when the eSIM is offered with the booking → 250 eSIMs
  • €6.00 average margin → €1,500
  • 10% of buyers top up once at a €3 margin → €75
  • ≈ €1,575 a month before costs

Example 2: A niche eSIM store

  • A travel community or content site sending 20,000 visitors a month to its store
  • 2% conversion → 400 eSIMs
  • €5.00 average margin → €2,000
  • Top-ups: 15% at €3 → €180
  • ≈ €2,180 a month before marketing costs

Example 3: An app with embedded eSIM

  • 50,000 monthly active travellers
  • 3% buy through the app → 1,500 eSIMs
  • €4.50 average margin (lower price, higher volume) → €6,750
  • Top-ups: 20% at €2.50 → €750
  • ≈ €7,500 a month — and likely a better wholesale tier, which raises the margin further

The five levers that increase profit

LeverWhat to doEffect
Attach rateOffer the eSIM at the moment of booking, not afterMore eSIMs per traveller
Average order valueLead with the mid-size plan; offer regional plansHigher margin per sale
Wholesale tierMove up a tier as volume growsLower cost on every plan
Top-upsRemind customers when data runs lowRepeat revenue, no acquisition cost
BundlesInclude the eSIM in premium packagesHigher perceived value

Why wholesale beats affiliate on earnings

An affiliate commission is a slice of someone else's retail price, usually on the first purchase only. A white-label reseller keeps the full margin and every top-up. Over a customer's lifetime the gap widens. See eSIM reseller vs affiliate.

Costs to remember

  • Payment processing on your checkout
  • Support time — usually small once you have good install instructions (playbook)
  • Marketing if you sell to new audiences (marketing guide)
  • Unused eSIMs — on Fully Signal, unused eSIMs can be refunded, so cancelled trips don't become dead stock

FAQ

Is reselling eSIMs profitable?

It can be, especially for businesses that already reach travellers. There's no stock or shipping, and the margin above wholesale plus top-ups adds up with volume.

What is a typical eSIM reseller margin?

It varies by destination and strategy. Many resellers price well below roaming while keeping a solid markup above wholesale. Test prices with your audience.

How do I earn more per eSIM?

Move up a wholesale tier, lead with mid-size and regional plans, and promote top-ups. Bundling the eSIM with a trip also raises perceived value.

How quickly can I start earning?
