Flying out of Perth airport on holiday, we rely on our smartphones for everything, from boarding passes to contactless payments. Almost every stage of a modern trip depends on staying connected, so reliable internet is a necessity, and knowing exactly what you’ll pay is the key to a comfortable journey.

That’s exactly what traditional international roaming fails to provide. Your home operator still dictates roaming zones, pricing, and billing rules. Modern travel eSIM providers, including Swiss company Yesim, offer a different approach.

Roaming and travel eSIM: four key differences

The difference becomes clear when you compare a week-long trip from Perth to Tokyo. Consider the terms offered by the Australian operator Telstra and the provider Yesim.

The Telstra International Roaming Day Pass for Zone 2 costs A$10 a day, or A$70 for a week. Yesim’s package for Japan for those same 7 days costs significantly less — A$41.66 ($29.40).

With Telstra, you get 2 GB a day, but any unused data is lost. Go over the limit, and an additional A$10 data pack is automatically activated. With Yesim, you get unlimited data for all 7 days of your holiday (for that same A$41.66).

Roaming terms are always determined by your home mobile plan. With a travel eSIM, you choose the plan that best suits your trip: the destination, the validity, and the data allowance.

Finally, your roaming bill isn’t settled until you return to Australia, and it may end up being considerably higher than expected. The price of a travel eSIM is fixed, known in advance, and paid for before the journey.

Yesim as a model of the new travel connectivity

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

The popularity of the travel eSIM from Yesim is driven by its flexibility and advanced features. The company offers both local plans (for Japan, for example) and regional or global plans — the Global Package (80+ countries) and the Global Plus Package (140+ countries). For those who don’t like fixed data limits, there’s the Pay & Fly plan on a pay-as-you-go model — you only pay for the data you use. Using SwitchLess Network technology, Yesim automatically connects your smartphone to the partner network offering the strongest available signal from a network of more than 800 operators.

You can get ready for your trip while still in Australia and activate the service once you’re in Japan. All you need to do is check that your smartphone supports eSIM, download the Yesim app, and choose a suitable plan.

Budget-conscious travellers can also test the service for just A$0.86 ($0.60) by buying a 500 MB trial plan. And the promo code GETYESIM15 gives new users a 15% discount on their first purchase.

Connectivity that puts travellers first

Ultimately, the choice comes down to what matters most to you: sticking with traditional roaming or sensible control over your spending. Roaming is convenient because it requires no setup, but you pay over the odds for that convenience.

Travel eSIM changes the rules of the game. You choose your plan, know the cost before you fly, and avoid unexpected roaming charges once you’re back home. That’s exactly what Yesim offers.
