eSIM wholesale & white-label reseller guides
Straight answers for anyone selling eSIM data under their own brand: how white-label eSIM works, wholesale pricing and margins, eSIM APIs, and how Fully Signal compares with the big eSIM brands.
What Is an eSIM and How Does It Work? (Explained for Businesses)
An eSIM is a SIM card built into a phone's hardware. Instead of inserting a plastic card, you download a mobile plan — an eSIM profile — by scanning a QR code or tapping an install link. Travellers use eSIMs to get local data abroad in minutes, and businesses resell them as an instant digital product.
Best eSIM API for Developers and Platforms in 2026
The best eSIM API gives you a live catalogue, one-call ordering that returns a ready-to-install eSIM, top-ups, usage and refunds, webhooks for status changes, a full sandbox and solid security such as scoped keys and IP allowlists. Fully Signal's REST API covers all of these and returns a white-label install page with every eSIM.
Fully Signal vs Holafly: Unlimited Retail eSIMs vs White-Label Wholesale
Holafly is a consumer travel eSIM brand best known for unlimited data plans sold directly to travellers. Fully Signal is a white-label wholesale platform that lets businesses sell eSIM data — fixed and unlimited — under their own brand at wholesale prices. Choose Holafly to buy one eSIM for a trip; choose Fully Signal to build your own eSIM product.
eSIM Wholesale Pricing Explained: Costs, Tiers and Margins
eSIM wholesale pricing is the cost a reseller pays per eSIM plan before adding its own margin. It depends on the destination, the data size, the validity and the network, and it usually drops as your volume grows through pricing tiers. Your profit is your retail price minus that wholesale cost.
Fully Signal vs Airalo: Which Is Better for eSIM Resellers?
Airalo is one of the best-known consumer eSIM stores and is a strong choice for an individual traveller. Fully Signal is a B2B white-label wholesale platform: businesses sell eSIM data under their own brand, set their own prices and keep the customer. If you want your own eSIM brand, Fully Signal is built for that; if you only want to refer travellers, an affiliate link is simpler.
How to Start an eSIM Reselling Business in 2026 (Step by Step)
To start an eSIM reselling business, pick a niche of travellers you can reach, open a white-label wholesale account, choose your top destinations, set retail prices above your wholesale cost, test the install flow, and launch through your website, app or booking channel. With Fully Signal you can do this with a free account and no minimum volume.
What Is a White-Label eSIM? The Complete Guide for Resellers
A white-label eSIM is a prepaid eSIM data plan that you sell under your own brand while a wholesale platform supplies the network access, provisioning and delivery behind the scenes. Your customer sees your name, logo and prices; the platform handles carriers, QR codes and activation.
Which Is the Best eSIM Reseller Platform in 2026? (And Why Fully Signal Leads)
The best eSIM reseller platform is the one that lets you sell under your own brand, at real wholesale prices, through both a panel and an API. Fully Signal does all three: white-label eSIM data in 210+ countries, tiered wholesale pricing, white-label install pages, a REST API with webhooks and a free sandbox — with no contract or minimum volume.
