Travel eSIM vs traditional roaming: Why the old model can no longer keep up with modern data-usage standards

A modern trip can no longer be broken down into separate online sessions. A smartphone is constantly connecting to maps, messaging, banking and transport apps, while the amount of data used can vary significantly from one day of a trip to the next.

Yet the outdated roaming model still tries to squeeze this fluctuating usage into identical daily packages with rigid data caps. A more flexible approach is offered by next-generation eSIM providers such as Yesim, a Swiss pioneer of the travel eSIM market.

Roaming from home mobile operators: why it no longer matches modern data-usage patterns

The first drawback of roaming is its high cost, as a week-long trip from Perth to Indonesia shows. Telstra’s International Roaming Day Pass in Zone 2 costs A$10 a day and includes 2 GB of data, so a week of use comes to A$70. Yesim’s unlimited plan for Indonesia for the same period costs US$29.40, or about A$41 at the current exchange rate.

The daily charging model creates another problem: it does not account well for uneven data use. With Telstra, any unused portion of the daily 2 GB does not carry over to the next day, and once the allowance is used up, another 2 GB is automatically added for A$10. This means that on a low-usage day, some of the data you have paid for goes unused, while on a high-usage day, you have to pay extra. A Yesim package is valid for the entire period selected, so there are no negative consequences if data use varies with the demands of the trip.

There is also a more fundamental difference: when the choice is made. With roaming, the way you connect is predetermined by your home mobile operator. A travel eSIM works the other way around: the itinerary becomes the starting point. Travellers choose the country, duration and required amount of data, pay for the plan and set it up through the app before leaving home.

If a trip covers several countries, you can choose a single regional or global package from the outset. For one destination, you can select the required number of days, unlimited data or a fixed data allowance. The total price is visible before payment, so connectivity costs can be included in the travel budget in advance, without worrying about an unexpected bill after returning home.

From eSIM technology to a complete travel service: how Yesim works

eSIM technology has become the foundation of an entire segment of the telecommunications industry that provides travellers with reliable connectivity around the world. One of the leading players in this industry, the Swiss company Yesim, has operated since 2019 and has helped shape the market. It provides connectivity to more than 4 million users across more than 200 destinations.

Yesim’s range of plans is built around real travel scenarios. The Global Package, covering more than 80 countries, and the Global Plus Package, covering more than 140, are designed for complex itineraries. The Pay & Fly plan works on a pay-as-you-go model, so users pay only for the data they actually use.

Switchless Network technology automatically connects Yesim customers to the network with the strongest signal among more than 800 partner operators. This is especially useful on remote beaches and in the mountains, where coverage can be unstable.

You can choose and set up a plan in the Yesim app, with no paperwork and no need to search for a SIM card at the airport. A trial package for less than A$1 lets you test connection quality in advance, while the promo code GETYESIM15 gives new users 15% off their first order.

Travelling in the smartphone era requires constant and flexible access to mobile data, while traditional roaming is still built around predefined daily periods and limits. That is why Australian travellers are choosing travel eSIMs, where plans can be selected to match a specific itinerary and actual data usage. Yesim develops this approach further by combining a flexible range of plans, global coverage and connection management through a single easy-to-use app.

Yesim is a travel eSIM provider that gives travellers flexible, app-based mobile data in 200+ destinations, so they can plan connectivity around their itinerary rather than a rigid daily roaming package. Visit the website for more information.
