FAQs

What are the cost and convenience benefits of using an eSIM compared to a traditional SIM card when travelling?

eSIMs can save you money when travelling internationally, as they help cut down on roaming charges and allow you to add several data plans to one device. This often results in lower costs compared to using traditional SIM cards.

They’re also incredibly easy to use. eSIMs activate instantly, eliminating the need to fumble with physical SIM cards. This makes them a great option for travellers who want dependable connectivity without the risk of losing or damaging a physical SIM. In short, eSIMs provide a straightforward, flexible, and budget-conscious way to stay connected while abroad.

What should I consider when selecting an eSIM plan for an extended stay in countries like the United States or Australia?

When choosing an eSIM plan for an extended stay in places like the United States or Australia, there are a few key points to consider to ensure you get the best value and reliable service.

Start by checking the validity period of the plan. Longer durations often work out to be more economical, especially if you’re planning to stay for several months. Next, think about the data allowance – if you’re someone who streams videos, uses navigation apps frequently, or works remotely, you’ll need a plan that can handle heavier usage.

It’s also worth looking for plans that provide local rates or even unlimited data, as these can help you stay connected without worrying about extra charges. Finally, opt for eSIMs with a straightforward activation process, so you can get up and running without any delays or complications once you arrive. By considering these aspects, you can ensure smooth and uninterrupted connectivity during your trip.

How reliable is eSIM network coverage in rural or remote areas, especially in countries like Australia and Japan?

eSIM network coverage in rural or remote areas can differ greatly depending on the country and the provider you choose. In Japan, major players like SoftBank and NTT Docomo provide widespread coverage, even in less populated or rural regions. This ensures travellers venturing into smaller towns or countryside areas can stay connected without much hassle.

In Australia, the situation is a bit more varied. While some providers offer extensive rural coverage, truly remote areas, such as the outback, may still face connectivity challenges. To avoid surprises, it’s a smart move to check the coverage maps of specific providers before heading into these regions.

Both countries have made strides in improving eSIM infrastructure, but doing a bit of homework on network partnerships and local coverage can save you from unexpected connectivity issues when travelling to less urbanised areas.
