The add-on customers thank you for.

Travel data is the rare add-on that solves a real problem. It sells well, it earns well, and is one line on the page that customers don't resent.

The problem

Fees have hit their ceiling.

Ancillary fatigue is real 01

Pages of optional extras that feel like a money grab rather than added value.

Margins need new lines 02

Your core product is priced to the bone. Growth has to come from somewhere that doesn't erode something else.

Add-ons rarely earn loyalty 03

Most add-ons are tolerated. Almost none are remembered fondly.

What you launch

An add-on that adds up.

Solves a real problem

Roaming anxiety, deleted.

Travellers already plan to buy data somewhere. Sell it to them at a natural point in your journey.

No stock, no fulfilment

Nothing to warehouse.

Digital delivery, one-tap install, and your retail price on our wholesale rates across 190+ destinations.

A reason to return

Useful beats tolerated.

Data that just works abroad is the add-on customers mention in reviews, not refund requests.

FAQ

Before you ask.

What attach rates are realistic?

It varies by placement and audience; the drivers are timing (sell when the need is top of mind) and friction (one-tap install). The scoping call covers benchmarks for your funnel.

Where should it sit in the flow?

Confirmation and follow-up comms convert best: the need is fresh and obvious.

Can we bundle it into plans or tiers?

Yes: sell it, bundle it into premium plans, or gift it to loyalty tiers. Same platform, your packaging.
