Why travel eSIM has made traditional roaming obsolete (and what makes Yesim stand out among providers)

In 2026, almost every aspect of international travel depends on a smartphone. Boarding passes, banking apps, reservations, maps, and transport services are all stored on one device. Yet mobile connectivity abroad often still operates under the outdated rules of roaming, where the home carrier determines the coverage zones, daily charges, and usage limits in advance, leaving travellers to adapt. A more practical alternative is offered by modern travel eSIM providers such as Yesim, the innovative Swiss company who is one of the pioneers of the travel eSIM market.

Why roaming no longer meets the needs of Australian travellers

Roaming was developed at a time when mobile connectivity abroad was used mainly for occasional phone calls and text messages. Today, smartphones constantly exchange data by loading navigation routes, receiving banking notifications, updating digital tickets, and keeping travellers connected with family and friends. Despite this, roaming still divides internet access into short billing periods and requires users to monitor every megabyte they consume.

The difference between the outdated roaming model and the Travel eSIM approach is easy to see when comparing a one-week trip from Australia to Japan.

The choice. Roaming terms are predetermined by the home carrier and tied to the user’s domestic mobile plan. With Travel eSIM, travellers choose a package that matches their destination, trip duration, and other travel requirements.

Seven days of connectivity in Japan with the Telstra International Roaming Day Pass costs A$70, consisting of seven separate daily charges of A$10, each including 2 GB of data. By comparison, Yesim’s unlimited seven-day plan for Japan costs US$29.40, or approximately A$41.66 at the current exchange rate.

Cost control. With roaming, the final cost depends on the number of daily passes activated and any additional charges, meaning the total expense often becomes clear only after the trip has ended. Even minimal internet usage or a background app update can trigger the full daily charge. With Travel eSIM, the total price is known before purchase, and current data usage can be monitored conveniently through the app.

What makes Yesim stand out among travel eSIM providers

The Swiss company Yesim has been operating in the travel eSIM market since 2019. Founded by telecommunications experts, the company now serves more than 3.5 million users across over 200 destinations worldwide.

Yesim has earned its reputation through competitive pricing, flexible data plans, and innovative technology. For example, unlimited data from Holafly for a 10-day trip to Thailand costs approximately A$55–56, depending on the exchange rate, while a comparable unlimited plan from Yesim costs around A$43.99 at the current exchange rate.

For more complex itineraries, Yesim offers its Global Package with coverage in more than 80 countries and Global Plus Package covering over 140 countries. Its Pay & Fly plan is available in more than 170 countries and operates on a pay-as-you-go model, meaning travellers pay only for the data they use.

Another key advantage is Switchless Network technology. It automatically connects users to the strongest available network from a pool of more than 800 partner operators. As a result, travellers do not need to determine which local carrier provides the best coverage in a particular location.

Travellers can test the quality of the service for approximately A$0.86 with a trial package that includes 500 MB of data. New users can also receive a 15% discount on their first purchase by using the promo code GETYESIM15.

Connectivity designed for the way people travel today

Roaming continues to follow a traditional model in which the home carrier sets the rules, while costs accumulate throughout the journey and only become fully apparent after returning home. Travel eSIM gives control back to travellers, and Yesim strengthens this approach with flexible plans, automatic network selection, and complete connectivity management through a single app.
